COVID-19 outbreaks surveillance through text mining applied to electronic health records.

BACKGROUND: The COVID-19 pandemic has caused significant disruptions to everyday life and has had social, political, and financial consequences that will persist for years. Several initiatives with intensive use of technology were quickly developed in this scenario. However, technologies that enhance epidemiological surveillance in contexts with low testing capacity and healthcare resources are scarce. Therefore, this study aims to address this gap by developing a data science model that uses routinely generated healthcare encounter records to detect possible new outbreaks early in real-time. METHODS: We defined an epidemiological indicator that is a proxy for suspected cases of COVID-19 using the health records of Emergency Care Unit (ECU) patients and text mining techniques. The open-field dataset comprises 2,760,862 medical records from nine ECUs, where each record has information about the patient's age, reported symptoms, and the time and date of admission. We also used a dataset where 1,026,804 cases of COVID-19 were officially confirmed. The records range from January 2020 to May 2022. Sample cross-correlation between two finite stochastic time series was used to evaluate the models. RESULTS: For patients with age 18 years, we find time-lag () = 72 days and cross-correlation () ~ 0.82, = 25 days and ~ 0.93, and = 17 days and ~ 0.88 for the first, second, and third waves, respectively. CONCLUSIONS: In conclusion, the developed model can aid in the early detection of signs of possible new COVID-19 outbreaks, weeks before traditional surveillance systems, thereby anticipating in initiating preventive and control actions in public health with a higher likelihood of success.

Self-efficacy of medical students in a hybrid curriculum course (traditional and problem-based learning) and associated factors.

Self-efficacy consists of the judgment of one's abilities to perform actions required to achieve a given performance, which has been considered predictive of performance. In academics, it means personal convictions in accomplishing a task to a defined degree of quality. Numerous studies have investigated medical students' self-efficacy in traditional and PBL curricula. However, few studies have addressed the hybrid PBL scenario (Hpbl) that simultaneously contemplates PBL, traditional teaching, and practical activities. An even smaller number have evaluated the factors associated with this entity. With these considerations, we aimed to investigate the self-efficacy belief in the hPBL curriculum and the factors associated with this entity. This quantitative observational cross-sectional study was held between August 2022 and November 2022 in Fortaleza, a city in Northeast Brazil with almost 3 million inhabitants. The medical course has 12 semesters. The first two semesters use traditional teaching and cover the basic cycle, followed by the third to eighth semesters which correspond to the pre-clinical and clinical cycle. From the third semester onwards, traditional teaching and PBL are used simultaneously, which we call a hybrid model of PBL. The scale "Scale of Self-efficacy in Higher Education" was applied, a questionnaire validated for the Portuguese language consisting of 34 questions, with answers on a Likert-type scale with ten points, divided into five dimensions. To verify the association between sociodemographic factors and self-efficacy, simple and multiple linear models with robust errors were used. In total, 412 students participated in this study, most of them women (70.1%). The average age of students was 22.9 years. All domains had medians greater than 8, which means strong self-efficacy. The following factors were associated with higher self-efficacy scores in general after the multivariate analysis: female gender (8.6 vs. 8.3, p-value = 0.014), working (8.8 vs. 8.5, p-value = 0.019) and participating in extracurricular activities (8.7 vs. 8.1, p-value = 0.019). We conclude that medical students studying in hybrid learning models showed strong levels of self-efficacy. In addition, participating in extracurricular activities was associated with higher self-efficacy scores and males presented lower levels of self-efficacy.

Having chronic back pain did not impact COVID-19 outcome in a low-income population - a retrospective observational study.

INTRODUCTION: Chronic back pain (CBP) is a major cause of years lived with disability. Social inequalities increase the prevalence and burden of CBP. Management of CBP was affected by restricted access to non-pharmacological treatments and outdoor activities during COVID-19 pandemic. OBJECTIVE: To determine the prevalence of CBP among patients with COVID-19 as well as the impact of having CBP in COVID-19 outcome in our low-income population. METHODS: Retrospective cohort of individuals with confirmed COVID diagnosis from May 2020 - March 2021, at Hospital Regional UNIMED (HRU) in Fortaleza, Ceará, Brazil. Data included comorbidities and household income. RESULTS: Among 1,487 patients, 600 (40.3%) were classified as having CBP. Mean age as well as income were similar in CBP and non-CBP groups, with more women in the CBP group. Hypertension and asthma, but not diabetes, were more prevalent in those with CBP. Need for emergency care, hospitalization, and admission to intensive care unit were similar regardless of having CBP. Dyspnea was more common in CBP vs. non-CBP groups, with 48.8% vs. 39.4% percentages, respectively (p = 0.0004). CONCLUSION: Having CBP prior to COVID did not impact the acute clinical outcome of COVID individuals of a low-income population.

Depression among Brazilian medical students exposed to remote learning and the role of scopophobia.

Medical education was greatly affected by the COVID-19 pandemic, and remote teaching through lectures and classes through videoconferencing was heavily used. However, the need to use cameras led to scopophobia, which is the fear of being watched, which can lead to psychological symptoms. Despite the relevance and prevalence of depression and the increase in the use of cameras for learning, research evaluating the impact of scopophobia on students' mental health is surprisingly scarce. Hence, to fill up this gap, a cross-sectional study was carried out in medical schools in Brazil. To assess the presence of depressed mood, the Patient Health Questionnaire-9 (PHQ-9) was applied. We used logistic regression models to verify the associations. The overall prevalence of positive PHQ9 found in our study was 62%. By studying the factors associated with a high risk of scopophobia, we could identify that the PHQ was statistically associated with scopophobia (odds ratio 2.43 (confidence interval 1.11-5.26), adjusted p value = .0269). Also, a lower family income, a higher number of household inhabitants, and female gender were associated. These results suggest that scopophobia is associated with depression, leading us to believe that interventions to mitigate this risk in students are opportune, especially if targeted at lower-income students.

Relationships Between Mental Health, Negative Feelings of COVID-19, and Parenting Among Pregnant Women in Fortaleza, Brazil.

INTRODUCTION: During the COVID-19 pandemic, the literature highlighted an increased risk of child abuse and the use of negative parenting practices. Furthermore, pregnancy during this time may have been challenging and generated different feelings regarding the pandemic and motherhood. Many pregnant women had other young children, underscoring the need to understand this scenario better. Therefore, the present study examined the predictive effect of indicators of mental health disorders, emotional discomfort with motherhood, and negative perceptions of COVID-19 on negative parenting practices. METHODS: The study used a cross-sectional design. Pregnant women (n = 303) who had other children younger than six years answered an online questionnaire during the physical distancing period due to COVID-19 in Fortaleza. A partially latent structural equation model (SEM) was used to test direct and indirect relations between the variables. RESULTS: The results revealed a direct positive relation between maternal mental health and the variables COVID-19 feelings, emotional discomfort with motherhood, and negative parenting practices. The stronger relationship was between maternal mental health and emotional discomfort with motherhood. The COVID-19 negative feelings also showed a direct positive relation to emotional discomfort with motherhood. Additionally, older mothers and those with fewer children tended to have less mental health disorders. Furthermore, being in a later trimester of pregnancy was linked to more negative feelings about motherhood. DISCUSSION: The study suggests that mothers experiencing mental health challenges are more likely to feel discomfort with motherhood and use negative parenting practices, highlighting a need for intervention.

Adult Congenital Heart Disease: Report from a Public Reference Hospital in Northeastern Brazil.

INTRODUCTION: The increasing worldwide number of adults with congenital heart disease (CHD) demands greater attention from health professionals. The purpose of this report is to describe the clinical demographic profile, frequency, and invasive treatment status of adults with CHD in a public reference hospital in northeastern Brazil. METHODS: This is a retrospective cross-sectional study including 704 patients attended between August 2016 and August 2020. Data were collected from virtual database. RESULTS: Patients' age varied from 17 to 81 years (mean 32±14; median 27 years); 294 (41.8%) patients were male, and 410 (58,2%) were female; 230 (32,7%) had diagnosis from age 18 and up. Cardiac complexity categories were "simple defects" (134 [19%] patients), "moderate complexity" (503 [71.5%]), and "great complexity" (67 [9.5%]). Atrial septal defect (ASD) was diagnosed in 216 (30.7%) patients, ventricular septal defect (VSD) in 101 (14.3%), tetralogy of Fallot in 93 (13.2%), and other CHD in 294 (41.8%). New York Heart Association (NYHA) functional classes were I (401 [57%]), II (203 [28.8%]), III (76 [10.8%]), and IV (24 [3.4%]). Complications were arrhythmias (173 [24%]) and severe pulmonary hypertension (69 [9.8%]). Invasive treatments were corrective surgery (364 (51.6%]), reoperation (28 [4.0%]), palliation (11 [1.6%]), interventional catheterization (12 [1.7%]), surgery plus interventional catheterization (5 [0.7%]), and preoperation (91 [12.9%]). Treatment was not required in 102 (14,5%) patients, and 91 (12.9%) were inoperable. CONCLUSION: The leading diagnosis was ASD. Frequency of unrepaired patients was high, mainly ASD, due to late diagnosis, which favored complications and denotes a matter of great concern.

Introduction to the Special Issue on Improving Early Childhood Nurturing Care to Support Childhood Development and Adult Health.

Background: Child development is an ongoing process that occurs from birth to adolescence and is shaped by various factors, such as genetics, the environment, and experiences [...].

Development and validation of a video-assisted liver biopsy technique using a minimally-invasive device.

BACKGROUND: Percutaneous liver biopsy is the gold standard technique for establishing the cause of cirrhosis and liver disease activity assessment. However, some cases of steatohepatitis or other chronic liver diseases show a high number of false negative results in samples obtained via the percutaneous route. This fact justifies performing a liver biopsy via the laparoscopic route. However, this is an expensive technique, with morbidities associated with pneumoperitoneum and anesthetic complications. The main objective of this study is to develop a video-assisted technique that uses only a minimally-invasive device for the liver biopsy and the optical trocar. Without additional trocars, this technique constitutes a less invasive procedure than the existing techniques in clinical practice. METHODS: This is a device development and validation study and patients submitted to abdominal laparoscopic surgery and required liver biopsy for moderate to severe steatosis were recruited. The patients were randomized into two groups: laparoscopic liver biopsy technique (n = 10, control group) and mini-laparoscopic liver biopsy technique (n = 8, experimental group). The times associated with procedure performance in both groups were evaluated using the Mann-Whitney or Kruskal-Wallis tests according to data distribution. RESULTS: At baseline, there was no statistical difference regarding gender and type of surgery. The experimental group had a significantly shorter time compared with the group that underwent the traditional procedure in mean procedure time (p = 0.003), biopsy time (p = 0.002) and hemostasis time (p = 0.003). CONCLUSIONS: The mini-laparoscopic biopsy device and technique showed to be capable of safely obtaining sufficient tissue samples, which was minimally invasive and in a shorter time than the classic technique.

Association of scopophobia with online learning fatigue among medical students in Brazil.

BACKGROUND: Scopophobia can be described in the medical field as the fear of being watched or stared at. Despite the relevance of scopophobia in remote learning scenarios, which have always existed and have been largely expanded during the pandemic in medical education, studies on this topic are exceedingly rare worldwide. Hence, to fill up this gap, a cross-sectional study of medical students was developed to assess the association of scopophobia with the prevalence of online learning fatigue. METHODS: A cross-sectional, quantitative, analytical study was carried out in Medical Schools of Brazil. To assess the risk of scopophobia, questions were developed, based on the literature on the topic. The Zoom Exhaustion & Fatigue Scale (ZEF) was used, and the questions have currently been validated for Brazilian Portuguese. Logistic regression models were also used to assess the relationship of scopophobia risk and ZEF scores. RESULTS: A total of 283 students from Brazil participated in the study. The median age was 23 years, and 64% of the participants were female. In total, 14.5% were considered to be at high risk for scopophobia. It was found that after adjusting for sex, income and number of residents in the household, scopophobia and the total zoom fatigue score remained associated. For the total score, each additional point on the scale increased the chance of scopophobia by 3%, and for the overall domain, 19% (p-values < 0.05). CONCLUSIONS: In conclusion, this study shows a relevant prevalence of students with scopophobia, which requires a differentiated approach on the part of teachers. The causes of scopophobia are often specific and have a psychological origin that goes beyond the usual pedagogical management. Therefore, motivation strategies are necessary in a general, as well as an individualized manner, aiming to favor the improvement of the online teaching and learning process.

Food insecurity among families with infants born during the COVID-19 pandemic in Fortaleza, Northeast Brazil.

PURPOSE: To assess the prevalence of food insecurity (FI) among families with infants born during the COVID-19 pandemic and its associated factors in Fortaleza, the fifth largest city in Brazil. METHODS: Data from two survey rounds of the Iracema-COVID cohort study collected at 12 (n = 325) and 18 months (n = 331) after birth. FI was measured using the Brazilian Household Food Insecurity Scale. FI levels were described according to potential predictors. Crude and adjusted logistic regressions with robust variance were used to assess factors associated with FI. RESULTS: In the 12- and 18-month follow-ups interviews, there was a 66.5% and 57.1% prevalence of FI, respectively. Over the study period, 3.5% of the families persisted in severe FI and 27.4% in mild/moderate FI. Households headed by mothers, with more children, low education and income, sustained maternal common mental disorders, and that were beneficiaries of cash transfer programs were the most affected by persistent FI. CONCLUSIONS: Although the prevalence of FI decreased in our sample, almost 60% of families in Fortaleza still have no regular access to enough and/or nutritionally appropriate food. We have identified the groups at higher FI risk, which can guide governmental policies.

Development and perceived usability evaluation of an interactive smartphone application for the teaching of hemodynamics and evaluation of arterial pulse pressure variation.

BACKGROUND: The use of fluids is the most frequently used therapy for circulatory shock. Its inadequate use has adverse effects, requiring hemodynamic goals, highlighting the use of pulse pressure variation due to its high accuracy. One of the problems related to this method is the difficulties in measuring the pulse pressure variation (PPV) in most monitors for clinical use. We assessed the qualitative aspects of perceived usability of a smartphone application (app), which, based on a photograph of the patient's arterial pulse wave, can help measure PPV and help in the diagnosis and management of shock cases. METHODS: To assess the software perceived usability, we used the System Usability Scale (SUS) applied to 30 physicians in 2 tertiary hospitals in Brazil. The software accuracy was measured using a sequence of 3 images with different values ​​of pulse pressure variation, comparing the obtained values ​​ with the gold standard. The educational interface of the app was evaluated qualitativelyfrom the spontaneous testimonies of the selected test participants.The project was approved by the Research Ethics Committee of Centro Universitário Christus. RESULTS: The analysis showed an average SUS of 86.3 points on a scale of 1-100 (above 80.3 is considered the best in terms of interface). The assessment of the application's accuracy when evaluating pulse pressure variation showed that the average variation of the measurements taken by the participants was small, with a good measure of repeatability and reproducibility. The app's educational interface was qualitatively evaluated, being praised by the users. CONCLUSIONS: It can be concluded that the developed mobile application showed excellent qualitative aspects of perceived usability results. More studies with this app will be required to evaluate the potential to help professionals with hemodynamic evaluation in emergency and intensive care settings.

Epidemiology of immune thrombocytopenia: study of adult patients at a referral hematology service in Northeastern Brazil.

Immune thrombocytopenia (ITP) is an acquired bleeding disorder observed in the clinical practice. Little is known about its epidemiology in Brazil. The present study was conducted at a hematology referral center which covers a population of over 8 million in 184 municipalities in the state of Ceará. The purpose of this study was to draw a demographic profile of adult ITP patients with regard to sex, age, geographical origin and distribution across the state, and the proportion of secondary ITP. Following ethics committee approval, information was collected with an ad hoc instrument. The sample consisted of 187 adult ITP patients attending the Walter Cantídio University Hospital in 2015. The median follow-up time was 67 months (range: 1 month to 29 years). Female sex (n = 154; 82.35 %) was strongly prevalent in all age brackets, with an overall female/male ratio of 4.7:1. The median age was 41 ± 16.1 with an interquartile range of 29-55.5 years; there was no difference between the genders. Secondary ITP (18/187; 9.6 %) displayed a bimodal distribution and a linear increase between 38 and >68 years of age. The results of this survey on the epidemiology of ITP in Brazil suggest that ethnic and geographical factors may have a great impact on age and sex distribution and on the distribution of secondary ITP.

Treatment was not required in 102 (14,5%) patients, and 91 (12.9%) were inoperable. Conclusion: The leading diagnosis was ASD. Frequency of unrepaired patients was high, mainly ASD, due to late diagnosis, which favored complications and denotes a matter of great concern.

Clinical outcome and prognosis of patients with acute myeloid leukemia submitted to chemotherapy with 5 years of follow-up.

OBJECTIVE: The purpose of this study was to evaluate the clinical-epidemiological profile, associated risk factors and clinical outcomes of patients with acute myeloid leukemia (AML), identifying the main causes of morbidity and mortality and overall survival rate of patients at five years of follow-up. METHOD: This was a retrospective cohort study evaluating the prognosis and clinical outcomes of 222 patients diagnosed with AML at three large hematology centers in Ceará (northeastern Brazil) over a period of five years. RESULTS: The mean age at diagnosis was 44.1 ± 16 years, with a female prevalence of 1.3:1. No additional relevant risk factors associated with the development of AML were found, except for the well-established cytogenetic assessment. The overall 5-year survival rate was 39.4% (95%CI: 35.47 - 42.17). The main causes of death were disease progression (37.72%; n = 84) and sepsis (31.58%; n = 70). CONCLUSION: The clinical outcomes in our sample of AML patients were similar to those of other reported groups. Disease progression and infection were the main causes of death. Access to diagnostic flow cytometry and karyotyping was greater in our sample than in the national average. As expected, overall survival differed significantly according to the risk, as determined by cytogenetic testing.

Prevalence and factors associated with adverse early childhood experiences: a population-based study in Ceará, Brazil.

OBJECTIVE: To estimate the prevalence of adverse childhood experiences and identify associated factors. METHODS: A population-based cross-sectional study comprised data from a sample of 3,200 households with 3,566 children under 6 years of age, representative of the state of Ceará, Brazil. A multistage sampling approach was used, with stratification among the state capital, Fortaleza, and the 28 countryside municipalities, in which 160 census tracts were randomly selected, each one with a cluster of 20 households. The outcome variable was structured based on adverse childhood experiences as suggested by the Center for Disease Control and Prevention, according to the number of situations to which the child was exposed: 0-2, 3-5, and 6-9. Ordinal logistic regression multivariate model was applied to assess associations. RESULTS: Among the 3,566 children studied, 89.7% (95%CI 88.7-90.7) were exposed to at least one adverse experience, of which the most prevalent were neglect, and emotional/physical abuse. The main factors associated were maternal advanced age and smoking, paternal absence, low education level of the head of the family, food insecurity and lack of a social support network. CONCLUSION: The study found a high occurrence of adverse early childhood experiences, particularly among preschool children born to mothers of older age, solo, who smoke and in a situation of social and economic vulnerability, including food insecurity, who should be target of control and prevention measures.

Primary Health Care during the COVID-19 pandemic in Fortaleza, Brazil: associated factors and pattern of use by mothers and children up to 18 months of age.

OBJECTIVE: To analyze the delay or failure to seek primary health care by the mother-child dyads during the COVID-19 pandemic, a practice that has a high potential to increase maternal and child morbidity and mortality. METHODS: Data from three survey rounds of the Iracema-COVID cohort study, collected 6, 12, and 18 months after birth, showed the patterns of postpartum attendance to primary health care consultation of the mother-child dyad. Crude and adjusted multinomial logistic regressions with robust variance were used to assess factors associated with nonattendance. RESULTS: Among the 314 cohort mothers, 25% did not attend any primary health care consultation during the 18-months postpartum, while 30% of the mothers did all three. Regarding the child, 75% had regular primary health care consultations in all three survey rounds, while 4% did not attend any in their first 18 months of life. By the end of the first COVID-19 wave, the proportion of mother and child who attended the consultations had fallen by 23 and 18%, respectively. The main factors associated with nonattendance were mothers aged below 25 years, and mothers with more than one child. CONCLUSION: An important delay or nonattendance to primary health care consultation by the mother-child dyad was observed during the COVID-19 pandemic. Such practice, with a high potential to increase maternal and child morbidity and mortality, was particularly frequent among younger mothers and those with more than one child.

Osteopenia of prematurity and associated nutritional factors: case-control study.

BACKGROUND: Preterm newborn nutrition affects postnatal skeletal growth and bone mineralization, but studies have not yet fully concluded the relationship between nutrition and osteopenia. This study was intended to investigate the impact of nutritional factors on osteopenia in preterm newborns. METHODS: This is a case-control study with babies born with gestational age ≤ 32 weeks in a high-risk maternity hospital, between 2018 and 2019. The population consisted of 115 newborns, being 46 cases (40%) and 69 controls (60%). Disease outcome was based on serum alkaline phosphatase levels > 900UL/l and hypophosphatemia < 4 mg/dl. Gestational data at birth and clinical and nutritional follow-up data during 8 weeks postnatally were assessed. Variables were assessed using regressive logistic models. FINDINGS: Preterm infants who were fed pasteurized fresh human milk with acidity ≥ 4 ºDornic are 5.36 times more likely to develop osteopenia (p = 0.035). Higher calcium intake, compared to controls, also increased the probability of disease occurrence [OR 1.05 (CI 1.006-1.1); p = 0.025], while the presence of a partner [OR 0.10 (CI 0.02-0.59); p = 0.038] and the shortest time using sedatives [OR 0.89 (CI 0.83-0.98); p = 0.010] were protective factors associated with osteopenia. Extremely low birth weight [OR 5.49 (CI 1.20-25.1); p = 0.028], sepsis [OR 5.71 (CI 1.35-24.2); p = 0.018] and invasive ventilatory support [OR 1.09 (CI 1.03-1.18); p = 0.007] were risk factors. CONCLUSIONS: Acidity and high calcium intake are the main nutritional factors associated with osteopenia of prematurity. Further studies on the use of human milk with lower acidity, recommendation and nutritional supplementation of calcium should be accomplished to guide prevention strategies in newborns at risk for osteopenia during hospital stay.
