Predictors of Venous Thromboembolism in COVID-19 Patients: Results of the COVID-19 Brazilian Registry

Background Previous studies that assessed risk factors for venous thromboembolism (VTE) in COVID-19 patients have shown inconsistent results. Our aim was to investigate VTE predictors by both logistic regression (LR) and machine learning (ML) approaches, due to their potential complementarity. Methods This substudy of a large Brazilian COVID-19 Registry included COVID-19 adult patients from 16 hospitals. Symptomatic VTE was confirmed by objective imaging. LR analysis, tree-based boosting and bagging were used to investigate the association of variables upon hospital presentation with VTE. Results Among 4,120 patients (55·5% men, 39·3% critical patients), VTE was confirmed in 6·7%. In multivariate LR analysis, obesity (OR 1·50, 95%CI 1·11-2·02); being an ex-smoker (OR 1·44, 95%CI 1·03-2·01); surgery ≤ 90 days (OR 2·20, 95%CI 1·14-4·23); axillary temperature (OR 1·41, 95%CI 1·22-1·63); D-dimer ≥ 4 times above the upper limit of reference value (OR 2·16, 95%CI 1·26-3·67), lactate (OR 1·10, 95%CI 1·02-1·19), C-reactive protein levels (CRP, OR 1·09, 95% CI 1·01-1·18); and neutrophil count (OR 1·04, 95%CI 1·005-1·075) were independent predictors of VTE. Atrial fibrillation, peripheral oxygen saturation/inspired oxygen fraction (SF) ratio and prophylactic use of anticoagulants were protective. Temperature at admission, SF ratio, neutrophil count, D-dimer, CRP and lactate levels were also identified as predictors by ML methods. Conclusion By using ML and LR analyse, we showed that D-dimer, axillary temperature, neutrophil count, CRP and lactate levels are risk factors for VTE in COVID-19 patients.

Hypothermia and neonatal morbimortality in very low birth weight preterm infants

ABSTRACT Objective: To assess the prevalence of hypothermia in the delivery room, at admission, and 2 to 3 hours after admission in the neonatal intensive care unit (NICU), factors associated and possible relationship with morbidity and mortality in preterm infants with very low birth weight (VLBW). Methods: Cross-sectional study with data collection based on a retrospective review of medical records and including infants born in 2016 and 2017, with birth weights <1500g, and gestational ages <34 weeks. Data about VLBW preterm infants, maternal data and temperature in the delivery room were analyzed. Hypothermia was considered when axillary temperature <36°C. For statistical analysis, the chi-square test or G test, canonical and Spearman correlation, and logistic regression were used. Results: 149 newborns (NB) were included in the study. The prevalence of hypothermia in delivery room, at admission to the NICU and 2 to 3 hours after admission was 25.8%, 41.5% and 40.2%, respectively. The temperature of NBs was directly proportional to gestational age (p<0.010), birth weight (p<0.010), and Apgar score (p<0.050). There was an inverse association with hypothermia in the delivery room and cesarean delivery (OR 0.25; p=0.016). Conclusions: Hypothermia was a prevalent problem in the studied population. The neonatal temperature was directly proportional to gestational age, birth weight and Apgar score. Hypothermia was associated with maternal factors, such as cesarean delivery. It is necessary to implement and improve strategies for its prevention.

Validation of modified sick neonatal score, a simple clinical score for assessment of severity of illness and outcome in new-borns for resource poor settings

Background: India contributes to 25% of the neonatal deaths worldwide each year. Neonatal disease severity scoring systems are needed to make standardized comparison between performances of different units and also give prognostic information. Existing scoring systems are unsuitable for resource-limited settings which lack investigations like pH, pO2/FiO2 ratio and base excess. Modified sick neonatal score (MSNS) is based on eight routinely measured clinical variables in NICUs namely respiratory effort, heart rate, axillary temperature, capillary refill time, random blood sugar, pulse oximeter saturation, gestational age and birth weight found to be useful in resource poor settings. The aim of the study was to validate MSNS score for its clinical utility in predicting mortality.Methods: This was a cross sectional study done at NICU of Mamata Medical College Hospital. The parameters required for the score were recorded immediately at admission in NICU from 1 January 2020 to 1 January 2021 and scored using Modified sick neonatal score (MSNS). The total score was calculated and outcome was noted. The data collected were coded and analzed using SPSS Statistics for Windows, v21.0 Chi square test, Mann-Whitney U test and ROC analysis.Results: Total of 355 neonates got discharged, while 45 neonates expired. For a cutoff score of ≤10, sensitivity and specificity were 85.9% and 51.1%, respectively. Positive predictive value and negative predictive value were 93.3% and 31.5%, respectively. The Area under the curve (AUC) was 0.811 (95%CI: 0.788-0.835), which indicates the accuracy of 81.1%.Conclusions: MSNS is a better suited neonatal disease severity score for resource poor settings.

Effectiveness of Combined Strategies for the Prevention of Hypothermia Measured by Noninvasive Zero-Heat Flux Thermometer During Cesarean Section

Background: Perioperative hypothermia (body temperature &lt;36°C) is a common complication of anesthesia increasing the risk for maternal cardiovascular events and coagulative disorders, and can also influence neonatal health. The aim of our work was to evaluate the impact of combined warming strategies on maternal core temperature, measured with the SpotOn. We hypothesized that combined modalities of active warming prevent hypothermia in pregnant women undergoing cesarean delivery with spinal anesthesia.Methods: Seventy-eight pregnant women were randomly allocated into three study groups receiving warmed IV fluids and forced-air warming (AW), warmed IV fluids (WF), or no warming (NW). Noninvasive core temperature device (SpotOn) measured maternal core temperature intraoperatively and for 30 min after surgery. Maternal mean arterial pressure, incidence of shivering, thermal comfort and newborn's APGAR, axillary temperature, weight, and blood gas analysis were also recorded.Results: Incidence of hypothermia was of 0% in AW, 4% in WF, and 47% in NW. Core temperature in AW was constantly higher than WF and NW groups. Incidence of shivering in perioperative time was significantly lower in AW and WF groups compared with the NW group (p &lt; 0.04). Thermal comfort was higher in both AW and WF groups compared with NW group (p = 0.02 and p = 0.008, respectively). There were no significant differences among groups for the other evaluated parameters.Conclusion: Combined modalities of active warming are effective in preventing perioperative hypothermia. The routine uses of combined AW are suggested in the setting of cesarean delivery.

A Survey of Physicians’ Opinion and Treatment Preferences Regarding Febrile Seizures in Children

Background: Fever of either low or high-grade is a big concern when present in the pediatric age group; it is much more worrisome if children are younger than 5 years of age. Fever can subside on its own or with the help of simple remedies and or medications. However, some children will develop seizures when they have a fever. Febrile seizures are one of the most common presenting complaints seen in pediatric patients in emergency room visits and physician consult. Two different types of seizures are seen in children, simple and complex seizures. Simple febrile seizures are non harming and self-limiting, while, complex seizures are prone to have long-term side effects on children. Febrile seizures can occur with or without a source of an underlying cause. In this study, we aimed to identify physicians’ opinions, knowledge, and suggestions to improve guidelines on current treatment trends for fever and fever’s association with febrile seizures in children less than 5 years of age. Objectives: To determine physicians’ opinion knowledge, and suggestions to improve guidelines on current treatment trends for fever and fever’s association with febrile seizures in children less than 5 years of age. Methods: A cross-sectional study plan was designed and conducted in June - July 2021 involving general physicians and pediatricians (n = 600). The questionnaire form including 15 closed-end questions was distributed to physicians. Descriptive statistics were used to analyse the data. Results: 100% of physicians prescribed antipyretics to control fever and or to prevent complications, especially febrile seizures. All participants were aware that axillary temperature of > 37.2 ° C is defined as fever. All most all, general physicians and most pediatricians used antipyretics to treat other associated symptoms and signs, even when the fever was absent. 76.3% believed that high fever might be an indicator of underlying serious occult bacterial infection. Almost all physicians (91.3%) advised parents to switch to the use of alternate medication when the fevers did not subside after initial treatment with paracetamol; everyone recommended that non-medical supportive treatments like tepid sponging along with antipyretics and ibuprofen to reduce the fever soonest possible. 68% of pediatricians and 90% of general practitioners believe that febrile seizures will cause brain damage. 74% of general practitioners preferred to refer children immediately to specialty centers, for further management of seizures. However, Pediatricians at tertiary care centers, as well as those in private practice used diazepam or lorazepam. Conclusion: Differences are negligible between general physicians and pediatricians while managing fever and fever complications including febrile seizures. Irrespective of the knowledge, awareness and the availability of fever guidelines by many national and international organizations, physicians are leaning towards child and parents comfort in treatment fever. The gap is wider in general physicians’ preparedness than pediatricians. A considerable gap exists to improve physicians' approach, diagnosis, and management of fever in the pediatric population.

Trends and predictive factors for treatment failure following artemisinin-based combination therapy among children with uncomplicated malaria in Ghana: 2005–2018

Background Since the introduction of artemisinin-based combination therapy (ACT) in Ghana in 2005 there has been a surveillance system by the National Malaria Control Programme (NMCP) and the University of Ghana Noguchi Memorial Institute for Medical Research (UG-NMIMR) to monitor the therapeutic efficacy of ACTs for the treatment of uncomplicated malaria in the country. We report trends and determinants of failure following treatment of Ghanaian children with artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) combinations. Methods Per protocol analyses as well as cumulative incidence of day 28 treatment failure from Kaplan Meier survival analyses were used to describe trends of failure over the surveillance period of 2005–2018. Univariable and multivariable cox regression analyses were used to assess the determinants of treatment failure over the period. Results Day 28 PCR-corrected failure, following treatment with ASAQ, significantly increased from 0.0% in 2005 to 2.0% (95% CI: 1.1–3.6) in 2015 (p = 0.013) but significantly decreased to 0.4% (95% CI: 0.1–1.6) in 2018 (p = 0.039). Failure, following treatment with AL, decreased from 4.5% (95% CI: 2.0–9.4) in 2010 to 2.7% (95% CI: 1.4–5.1) in 2018, though not statistically significant (p = 0.426). Risk of treatment failure, from multivariable cox regression analyses, was significantly lower among children receiving ASAQ compared with those receiving AL (HR = 0.24; 95% CI: 0.11–0.53; p < 0.001); lower among children with no parasitaemia on day 3 compared with those with parasitaemia on day 3 (HR = 0.02; 95% CI: 0.01–0.13; p < 0.001); and higher among children who received ASAQ and had axillary temperature ≥ 37.5 °C on day 1 compared with those with axillary temperature < 37.5 °C (HR = 3.96; 95% CI: 1.61–9.75; p = 0.003). Conclusions Treatment failures for both ASAQ and AL have remained less than 5% (below WHO’s threshold of 10%) in Ghana since 2005. Predictors of treatment failure that need to be considered in the management of uncomplicated malaria in the country should include type of ACT, day 3 parasitaemia, and day 1 axillary temperature of patients being treated.

Effect of a Low-Dose/High-Frequency Training in Introducing a Nurse-Led Neonatal Advanced Life Support Service in a Referral Hospital in Ethiopia

Background and Objective: In Ethiopia, birth asphyxia causes ~30% of all neonatal deaths and 11–31% of deaths among neonates delivered in healthcare facilities that have breathing difficulty at birth. This study aimed to examine the impact of low-dose, high-frequency (LDHF) training for introducing a nurse-led neonatal advanced life support (NALS) service in a tertiary care hospital in Ethiopia.Methods: Through a retrospective cohort study, a total of 12,001 neonates born post-implementation of the NALS service (between June 2017 and March 2019) were compared to 2,066 neonates born before its implementation (between June 2016 and September 2016). Based on when the neonates were born, they were divided into six groups (groups A to F). All deliveries occurred in the inpatient Labor and Delivery Unit (LDU) at St. Paul's Hospital Millennium Medical College. The number of neonatal deaths in the LDU, neonatal intensive care unit (NICU) admission rate, and proportion of neonates with normal axillary temperature (36.5–37.5°C) within the first hour of life were evaluated. Data were analyzed using the χ2 test, and p-values &lt; 0.05 were considered statistically significant. Following the implementation of the NALS service, semi-structured interviews with key stakeholders were conducted to evaluate their perception of the service; the interviews were recorded, transcribed, and coded for thematic analysis.Results: There was a decrease in the proportion of neonates who died in the LDU (from 3.5 to 1%) during the immediate post-implementation period, followed by a sustained decrease over the study period (p &lt; 0.001). The change in the NICU admission rate (from 22.8 to 21.2%) was insignificant (p = 0.6) during this initial period. However, this was followed by a significant sustained decrease (7.8% in group E and 9.8% in group F, p &lt; 0.001). The proportion of newborns with normal axillary temperature improved from 46.2% during the initial post-implementation period to 87.8% (p &lt; 0.01); this proportion further increased to 99.8%. The program was perceived positively by NALS team members, NICU care providers, and hospital administrators.Conclusion: In resource-limited settings, LDHF training for neonatal resuscitation improves the neonatal resuscitation skills and management of delivery room attendants.

Baseline malaria prevalence at the targeted pre-elimination districts in Ethiopia

Background Encouraged by the previous success in malaria control and prevention strategies, the Ethiopian ministry of health launched malaria elimination with a stepwise approach by primarily targeting the low-transmission Districts and their adjacent areas/zones in order to shrink the country’s malaria map progressively. Hence, this community survey was conducted to establish baseline malaria information at the preliminary phase of elimination at targeted settings. Methods A community-based cross-sectional survey was conducted at 20 malaria-elimination targeted Districts selected from five Regional states and one city administration in Ethiopia. The GPS-enabled smartphones programmed with Open Data Kit were used to enumerate 9326 study households and collect data from 29,993 residents. CareStart™ Malaria PAN (pLDH) Rapid Diagnostic Tests (RDTs) were used for blood testing at the field level. Armpit digital thermometers were used to measure axillary temperature. Result Overall malaria prevalence by RDTs was 1.17% (339/28973). The prevalence at District levels ranged from 0.0 to 4.7%. The proportion of symptomatic cases (axillary temperature > 37.5oc) in the survey was 9.2% (2760/29993). Among the 2510 symptomatic individuals tested with RDTs, only 3.35% (84/2510) were malaria positive. The 75.2% (255/339) of all malaria positives were asymptomatic. Of the total asymptomatic malaria cases, 10.2% (26/255) were under-five children and 89.8% (229/255) were above 5 years of age. Conclusion The study shows a decrease in malaria prevalence compared to the reports of previous malaria indicator surveys in the country. The finding can be used as a baseline for measuring the achievement of ongoing malaria elimination efforts. Particularly, the high prevalence of asymptomatic individuals (0.88%) in these transmission settings indicates there may be sustaining hidden transmission. Therefore, active case detection with more sensitive diagnostic techniques is suggested to know more real magnitude of residual malaria in the elimination-targeted areas.

A semi-randomized study determining the psychological and physical effects of three types of eye masks on adult women

Background: Warm compresses are one of the nursing techniques clinically used to improve patients’ comfort and promote the treatment efficacy. Here the effects of eye masks (EM), heated eye masks (HEM), and aroma-scented heated eye masks (AHEM) and their potential as a nursing technique to provide comfort were studied.Methods: Participants in this study were 42 healthcare professionals (female, 20–60 years of age), who voluntarily consented to participate. They participated in all three interventions with EM, HEM, and AHEM at an interval of at least 1 week between interventions. Indicators used were low frequency to high frequency ratio (LF/HF), blood flow, axillary temperature, pulse rate, blood pressure, the salivary α-amylase activity (SAA), and the Profile of Mood States Second Edition (POMS).Results: Of 42 participants in total, 32 were included in the analysis. Their mean age was 46.8 years. The blood flow and axillary temperature values significantly increased and the LF/HF values and the pulse rates significantly decreased after the use of EM, HEM, or AHEM. The POMS Total Mood Disturbance (TMD) score and scores for six POMS subscales significantly decreased after the use of EM, HEM, or AHEM.Comparisons among the three groups showed differences in LF/HF. Scores for subscales of POMS also differed among the three groups.Conclusions: These results suggest that the use of EM, HEM, or AHEM intervention is safe with no major body burden. Parasympathetic nerves may be dominant after the EM, HEM, or AHEM interventions The TMD score improved after the EM, HEM, or AHEM intervention. The data suggest that the AHEM use is particularly effective in alleviating depression, dejection, and confusion after the intervention. These findings indicates that the EM, HEM, or AHEM use holds potential as a nursing technique to provide comfort.Trial registration: UMIN Clinical Trials Registry (UMIN000018409Trial registration number: UMIN-CTR R000021207Date of registration: 07/24/2015
