ABSTRACT

BACKGROUND: Electroencephalogram oscillations during general anesthesia may change as a function of cognitive and physical health. This study aimed to characterize associations between anesthesia-induced oscillations and postoperative outcomes in cardiac surgery patients over 60 years.

METHODS: This was a prespecified secondary data analysis from the Minimizing Intensive Care Unit Dysfunction with Dexmedetomidine-induced Sleep (MINDDS) study. Participants were admitted from home for elective cardiac surgery with cardiopulmonary bypass. The primary outcome was postoperative delirium obtained using the Confusion Assessment Method. Secondary outcomes were non-home discharge and 30-day readmission. The exposure of interest was alpha power measured during the maintenance phase of isoflurane-general anesthesia. Confounding cognitive and physical health variables were collected.

RESULTS: Of 394 participants in the MINDDS study, 302 had analyzable electroencephalograms. The incidence of postoperative delirium was 11.1 %. Odds of postoperative delirium decreased by 14 % for every decibel increase in alpha power (OR 0.86, 95 % CI: 0.78 to 0.95; P = 0.004). This finding was not significant in adjusted analysis (OR_adj 0.92, 95 % CI: 0.81 to 1.03; P = 0.154). Non-home discharge setting findings were not associated with alpha power. The odds of 30-day readmission decreased by 20 % for every decibel increase in alpha power (OR_adj 0.80, 95 % CI: 0.71 to 0.91; P < 0.001). Findings were conserved in exploratory and sensitivity analyses.

CONCLUSIONS: In this study anesthesia-induced oscillations were associated with postoperative outcomes; however, these were not independently associated with delirium or discharge disposition after considering preoperative cognitive and physical health. These oscillations were robustly associated with 30-day readmission however, which may help anesthesiologists identify high-risk patients, offering benefits beyond the operating room.

ABSTRACT

This study proposes a deep learning framework, DLPVI, which integrates projection, view-by-view backprojection (VVBP), and image domains to improve the quality of high-sparse-view and ultra-sparse-view cone-beam computed tomography (CBCT) images. The DLPVI comprises a projection domain sub-framework, a VVBP domain sub-framework, and a Transformer-based image domain model. First, full-view projections were restored from sparse-view projections via the projection domain sub-framework, then filtered and view-by-view backprojected to generate VVBP raw data. Next, the VVBP raw data was processed by the VVBP domain sub-framework to suppress residual noise and artifacts, and produce CBCT axial images. Finally, the axial images were further refined using the image domain model. The DLPVI was trained, validated, and tested on CBCT data from 163, 30, and 30 real patients respectively. Quantitative metrics including root-mean-square error (RMSE), peak signal-to-noise ratio (PSNR), structural similarity (SSIM), and feature similarity (FSIM) were calculated to evaluate the method performance. The DLPVI was compared with 15 state-of-the-art (SOTA) methods, including 2 projection domain models, 10 image domain models, and 3 projection-image dual-domain frameworks, on 1/8 high-sparse-view and 1/16 ultra-sparse-view reconstruction tasks. Statistical analysis was conducted using the Kruskal-Wallis test, followed by the post-hoc Dunn’s test. Experimental results demonstrated that the DLPVI outperformed all 15 SOTA methods for both tasks, with statistically significant improvements (p < 0.05 in Kruskal-Wallis test and p < 0.05/15 in Dunn’s test). The proposed DLPVI effectively improves the quality of high- and ultra-sparse-view CBCT images.

ABSTRACT

CMML is a heterogenous myelodysplastic/myeloproliferative neoplasm (MDS/MPN) sharing both diseases’ molecular and clinical phenotypes. Several models are used to risk-stratify patients diagnosed with CMML. Inflammation plays a pivotal role in developing the disease or its progression and has been linked to worse outcomes. Serum albumin (SA) is an inflammatory marker and/or surrogate for co-morbidities. While the role of SA has been investigated in myelodysplastic syndrome (MDS), acute myeloid leukemia (AML), multiple myeloma, and other cancers, its prognostic value in CMML remains unclear. We identified 919 patients diagnosed with CMML with known SA levels at the time of diagnosis or prior to any therapy. We divided patients into three groups based on SA levels: < 3.5 g/dL, 3.5-4.0 g/dL and > 4.0 g/dL. We then compared the baseline characteristics and outcomes of these three groups. Patients with SA < 3.5 g/dL had higher risk disease according to the CPSS-Molecular model, WHO 2022 classification, and FAB classification. Additionally, patients with SA < 3.5 g/dL had a higher median blast percentage, ferritin levels, WBC, and monocyte count (P < 0.001). These patients were also more likely to be cytopenic and RBC transfusion-dependent (RBC-TD) (P < 0.001). In multivariable Cox regression analysis, SA was independently significant for predicting overall survival (OS) after adjusting for CPSS-Molecular risk, WHO 2022 subtype, proliferative CMML (FAB classification), RBC-TD, and bi/pancytopenia. Therefore, SA is an independent prognostic factor for OS among patients with CMML. Low SA may reflect inflammatory disease status or a surrogate for co-morbidities. Risk stratification models should incorporate serum albumin levels to refine their prognostic value.

ABSTRACT

BACKGROUND: Hemoglobin, albumin, lymphocyte and platelet (HALP) score is derived from the counts of hemoglobin, albumin, lymphocytes, and platelets. It serves as a valuable tool for assessing both inflammation and nutritional status in critically ill patients. However, there hasn’t been a specific study exploring the role of the HALP score in critically ill patients. Additionally, whether the HALP score exhibits an incremental effect on the Sequential Organ Failure Assessment (SOFA) score remains unknown.

METHODS: In this study, we used the Medical Information Mart for Intensive Care (MIMIC-IV) version 2.2 database to evaluate the predictive value of HALP score for critically ill patients. The primary outcome investigated was intensive care unit (ICU) death, and the secondary outcomes included in-hospital mortality, ICU length of stay (LOS), hospital LOS, and 28-day mortality.

RESULTS: We analyzed 20,083 critically ill patients. In logistic regression, a low HALP score (HALP score < 3.56) showed higher risk of ICU death (adjusted odds ratio: 1.41, 95% confidence interval [CI]: 1.25 to 1.59). Additionally, the HALP score improved the predictive ability of the SOFA score (∆Area under curve: 0.009, p < 0.001). In Cox proportional hazards models, a low HALP score (HALP score < 3.2) was also associated with a higher risk of 28-day mortality (adjusted hazard ratio: 1.52, 95% CI: 1.33 to 1.74).

CONCLUSION: HALP score is associated with short-term mortality. Additionally, HALP score showed an incremental effect on SOFA score in predicting short-term mortality.

ABSTRACT

BACKGROUND: Gestational diabetes is one of the most prevalent diseases in pregnancy, with an incidence of 5 to 18% in Brazil, and is associated with high morbidity rates. The first-line treatment is insulin, although some recent studies have indicated that metformin might also be effective. Metformin is safe in pregnancy and appears to produce better results than insulin, including reduced gestational weight gain (GWG) and smaller gestational-age newborns. Few studies have been conducted on this topic in low- and middle-income countries.

METHODS: We designed an open randomized controlled trial comparing two treatments for pregnant women with type II diabetes mellitus (DM) and gestational diabetes (DMG): the metformin group (intervention) and the insulin group (as a routine service). The primary outcome is glycemic control. The secondary outcomes are GWG, the occurrence of hypertensive syndromes, macrosomia, and neonatal hypoglycemia. The sample will comprise 92 pregnant women, 46 per group. The inclusion criteria will be GDM or type II DM requiring medication for glycemic control, singleton pregnancy, and gestational age under 34 weeks. The exclusion criteria will be current treatment with any medication for glycemic control, type I DM, and intolerance to the study medications (metformin or insulin). Women will be routinely followed during antenatal care, childbirth, and the postpartum period. Statistical analyses will include the intention-to-treat approach and a comparison between the two groups.

DISCUSSION: Considering the Brazilian socioeconomic reality and the safety of metformin demonstrated in previous trials, we expect that the MevIP study will demonstrate that metformin is an adequate and appropriate medication for GDM treatment in the Brazilian population, representing an alternative to insulin for GDM.

TRIAL REGISTRATION: This protocol has been registered prospectively in ReBEC under the ID RBR-3j3cktx in August 11, 2023.

ABSTRACT

BACKGROUND: Our previous 2007 study reported a 19.4% rate of biphasic anaphylaxis in Kingston, Ontario. Since then, few updates have been published regarding the etiology and risk factors of biphasic anaphylaxis. This study aimed to describe the incidence of and predictors of biphasic anaphylaxis in a single centre through a retrospective evaluation of patients with diagnosed anaphylaxis.

METHODS: From November 2015 to August 2017, all patients who presented to the emergency department at two hospital sites in Kingston given a diagnosis of “allergic reaction,” “anaphylaxis,” “drug allergy,” or “insect sting allergy,” were evaluated. Patients were contacted sometime after ED discharge to obtain consent and confirm symptoms and timing of the reaction. A trained allergist determined if criteria for anaphylaxis were met and categorized the reactions as being uniphasic, biphasic, or non-anaphylactic biphasic. A full medical review of the event ensued, and each type of anaphylactic event was statistically compared.

RESULTS: Of 138 anaphylactic events identified, 15.94% were biphasic reactions, 79.0% were uniphasic, and 5.07% were classified alternatively as a non-anaphylactic biphasic reaction. The average time of a second reaction was 19.0 h in patients experiencing biphasic reactivity. For biphasic anaphylaxis, the symptom profiles of second reactions were significantly less severe (p = 0.0002) compared with the initial reaction but significantly more severe than non-anaphylactic biphasic events (p < 0.0001).No differences of management were identified between events.

CONCLUSION: The incidence of biphasic reactions in this cohort was 15.94% and the average second-phase onset was 19.0 h. In biphasic reactivity, it appears that the symptom profile second reaction is less severe compared to the first reaction.

ABSTRACT

BACKGROUND: Conventional method of using carbide burs for caries removal has long been shown to be quite successful. Nevertheless, it has some disadvantages, including excessive dentin removal, and patient discomfort.

OBJECTIVE: The aim of this study was to compare and assess time consumption and the caries removal effectiveness of Smart prep bur II and Brix 3000 in addition to carbide bur (as a control group).

MATERIALS AND METHODOLOGY: 60 newly extracted carious human permanent premolars were collected from patients between 14 and 24 years old. Teeth were extracted for orthodontic reasons. Caries should be deep but without pulp involvement and all teeth have only one surface caries (mesial or distal class II carious lesions). Samples have been collected, cleaned and stored in distilled water until starting the experiment. Teeth were divided into two groups in addition to third group that represent a control group (n = 20). Infected carious dentin for each group was removed using Smart prep bur II (polymer bur) or Brix 3000 (caries dissolving enzymes). Conventional carbide bur was used to remove carious dentin in the control group. Two parameters were assessed: time consumption and caries removal efficacy. Cavities were inspected by stereomicroscopy and caries removal was categorized after application of caries detector dye.

RESULTS: Regarding the amount of time needed for soft caries removal and the efficacy of total amount removed of infected dentine, there was no statistically significant difference (P ˂ 0.001) found between the two minimally invasive groups. While for carbide bur group, recorded values were considered statistically significant (P > 0.001) when compared to the two minimally invasive groups.

CONCLUSION: within the limitation of this in-vitro study, both Smart Prep bur II and BRIX 3000 are efficient methods for caries removal by minimally invasive approach. However, both are less effective and time-consuming methods when compared to conventional carbide bur.

ABSTRACT

BACKGROUND: Data suggest excess mortality is associated with loiasis, which is endemic to Central Africa, although the underlying mechanisms remain unknown. We hypothesized that there could be an association between Loa loa microfilarial densities (MFD) and lower spleen volume (SV) due to micro-obstruction linked to circulating microfilariae (mf). This could result in functional hyposplenia and a higher burden of infections. Our objective was to investigate the impact of L. loa MFD and malaria on spleen’s bi-dimensional dimensions, volume, and parenchymal lesions.

METHODS: We included 981 participants aged 18-88 years in a cross-sectional study conducted in May-June 2022 in the Republic of the Congo. Centralized ultrasonographic examination was performed. The primary outcomes included SV, splenomegaly (cranio-caudal-distance ≥ 13 cm), and anatomical hyposplenia (AH) (SV ≤ 80, ≤ 110 or ≤ 150 cm³). Blood samples were analyzed for L. loa MFD, Plasmodium-PCR, Anti-Plasmodium falciparum-IgG, total IgM, sickle-cell disease status, and hematological abnormalities. Linear and logistic regressions were used to assess these associations.

RESULTS: Among 981 participants, 139 (14.1%) had splenomegaly, and 26 (2.7%) and 175 (17.8%) had SV ≤ 80 and ≤ 150 cm³, respectively. L. loa microfilariae were detected in 353 (35.6%) participants. A gradient effect was observed in each model, with the highest MFD (> 30,000 mf/ml) having the highest adjusted odds ratio of 17.94 (95% CI: 2.91-110.76, P = 0.002), 5.94 (95% CI: 1.40-25.17, P = 0.016), and 5.77 (95% CI: 1.95-17.12, P = 0.002) for SV ≤ 80, 110, and 150 cm³, respectively. Anti-P. falciparum-IgG levels were gradually associated with splenomegaly. Fourteen participants met the criterion for hyper-reactive malarial splenomegaly (HMS). Conversely, higher L. loa MFD was correlated with AH, with an attributable fraction of 25%, and the presence of splenic parenchymal lesions.

CONCLUSIONS: This study provides a detailed description of spleen morphology and the factors influencing its size in a rural central African population. It demonstrates a strong association between L. loa MFD and reduced SV, suggesting that loiasis may lead to AH, and potentially to functional hyposplenia, with consequences such as increased susceptibility to bacterial infections. Malaria was associated with splenomegaly, with a figure of HMS consistent with estimates from other African countries.

ABSTRACT

BACKGROUND: Parental school involvement is critical for students’ academic and educational success. This study addresses a research gap by conducting latent class and correspondence analyses to uncover and visually depict the intricate relationships between parental school involvement and its barriers.

METHODS: Data were obtained from 1,307 parents of students in grades 4 to 9 in China. Students in grades 4 to 9 experience preadolescence (grades 4 to 6) and early adolescence (grades 7 to 9), which are critical periods of transition in individual development. The latent class analysis revealed sub-populations of parental school involvement and its barriers. The correspondence analysis demonstrated the relationship between the groups of both parental school involvement and its barriers.

RESULTS: The results showed: (1) six distinct groups of parental school involvement, namely the High Involvement in Child’s Things, All High Involvement, High Initiative Involvement, High Passive Involvement, Medium Involvement, and Low Involvement groups; (2) five groups of barriers to parental school involvement, namely the High Work-Transportation, High Work, Medium Personal, High Transportation, and None Barriers groups; (3) a visual pattern of the relationship between six groups of parental school involvement and five groups of barriers to parental school involvement. Specifically, the All High Involvement and High Initiative Involvement groups were closer to the None Barriers class; Medium Involvement was related to High Work Barriers; Low Involvement to Medium Personal Barriers; and High Passive Involvement to High Transportation Barriers.

CONCLUSIONS: This study clarifies relationships between the latent groups of parental involvement in school and the latent groups of barriers to involvement, which support the reformulated explanatory model of barriers to parental involvement in education.

ABSTRACT

BACKGROUND AND OBJECTIVES: Chronic kidney disease (CKD) is a progressive illness linked to higher rates of morbidity and death. One of the main causes of CKD is diabetes mellitus (DM), and oxidative stress is essential to the disease’s development. It has been demonstrated that the natural antioxidant melatonin reduces inflammation and oxidative damage in renal tissues. Given the lack of robust evidence, this double-blind clinical trial sought to investigate the effects of melatonin supplementation on oxidative stress and inflammatory markers in diabetic CKD patients.

MATERIALS AND METHODS: This trial included 41 diabetic patients with CKD (stages 3-4) from Shariati Hospital, Tehran, Iran. For ten weeks, participants were randomized to receive either a placebo or 5 mg of melatonin twice a day. Baseline characteristics, dietary intake, physical activity, and anthropometric measurements were recorded. Oxidative stress (TAC, TOS, MDA) and inflammatory markers (IL-6, hs-CRP) were measured before and after the intervention. Statistical analysis was performed using SPSS, with significance set at p < 0.05.

RESULTS: The 10-week trial was completed by 41 participants in total, and no adverse effects were noted. Dietary intake, physical activity, and anthropometric parameters did not significantly differ between the melatonin and control groups in baseline characteristics. Melatonin supplementation decreased oxidative stress and inflammatory biomarkers, including hs-CRP, MDA, TOS, and IL-6. However, these changes were not statistically significant.

CONCLUSION: Our study showed that melatonin supplementation did not significantly affect oxidative stress or inflammatory markers, including TAC, TOS, MDA, IL-6, and hs-CRP, in diabetic patients with CKD. Despite a decrement in TOS, MDA, IL-6, and hs-CRP levels after 10 weeks, this was not statistically significant. Further studies with larger sample sizes, greater dosages, and longer follow-up periods are recommended.
