Asthma control associated with anxiety and depression in asthmatic children following post-acute COVID-19.

BACKGROUND: Poor asthma control may adversely affect mental health. Our study investigates the correlation between inadequate asthma control, exhaled nitric oxide (FENO) levels, and anxiety and depression among pediatric asthma patients with COVID-19. METHODS: This prospective case-control study enrolled 520 asthmatic children (8-15 years), including 336 patients diagnosed with COVID-19 after rapid antigen testing at home and 184 age-matched asthmatic patients without COVID-19 infection. FENO and spirometry were performed 1 month after COVID-19 infection. Scores for Child Anxiety-Related Disorders (SCARED) and depression screen derived from Patient Health Questionnaire-9 (PHQ-9) to assess their mental health status. Childhood asthma control test (C-ACT), FENO levels, and spirometry were correlated with the SCARED and PHQ-9 questionnaires. RESULTS: SCARED subscales, including generalized anxiety disorder, social anxiety disorder, school avoidance, and depression scores from PHQ-9, exhibited a significant increase in asthmatic patients diagnosed with COVID-19 (p < .05). Among asthmatic children with SARS-CoV-2 infection, the poor asthma control group exhibited the highest SCARED and PHQ-9 measurements (p < .01). Multiple linear regression analysis indicated that reduced C-ACT scores and elevated FENO levels in asthmatic children with COVID-19 were significant risk factors for both anxiety and depression scores (p < .05). Lower C-ACT scales were associated with high scores of SCARED (r = -0.471) and PHQ-9 (r = -0.329) in asthmatic children (p < .001). CONCLUSIONS: The current study emphasizes the need for healthcare professionals to closely monitor asthma control in asthmatic children to prevent heightened risks of depression and anxiety during the ongoing COVID-19 pandemic.

Factors associated with immune responses to SARS-CoV-2 vaccination in individuals with autoimmune diseases.

Patients with autoimmune diseases are at higher risk for severe infection due to their underlying disease and immunosuppressive treatments. In this real-world observational study of 463 patients with autoimmune diseases, we examined risk factors for poor B and T cell responses to SARS-CoV-2 vaccination. We show a high frequency of inadequate anti-spike IgG responses to vaccination and boosting in the autoimmune population but minimal suppression of T cell responses. Low IgG responses in B cell-depleted patients with multiple sclerosis (MS) were associated with higher CD8 T cell responses. By contrast, patients taking mycophenolate mofetil (MMF) exhibited concordant suppression of B and T cell responses. Treatments with highest risk for low anti-spike IgG response included B cell depletion within the last year, fingolimod, and combination treatment with MMF and belimumab. Our data show that the mRNA-1273 (Moderna) vaccine is the most effective vaccine in the autoimmune population. There was minimal induction of either disease flares or autoantibodies by vaccination and no significant effect of preexisting anti-type I IFN antibodies on either vaccine response or breakthrough infections. The low frequency of breakthrough infections and lack of SARS-CoV-2-related deaths suggest that T cell immunity contributes to protection in autoimmune disease.

A simple and highly sensitive flexible sensor with extended-gate field-effect transistor for epinephrine detection utilizing InZnSnO sensing films.

This study introduces a straightforward method for depositing InZnSnO films onto flexible polyimide substrates at room temperature, enabling their application in electrochemical pH sensing and the detection of epinephrine. A comprehensive analysis of these sensing films, spanning structural, morphological, compositional, and profiling characteristics, was conducted using diverse techniques, including X-ray diffraction, atomic force microscopy, X-ray photoelectron spectroscopy, and secondary ion mass spectroscopy. The investigation into the influence of oxygen flow rates on the performance of InZnSnO sensitive films revealed a significant correlation between their structural properties and sensing capabilities. Notably, exposure to an oxygen flow rate of 30/2 (Ar/O2) the ratio of resulted in the InZnSnO sensitive film demonstrating outstanding pH sensitivity at 59.58 mV/pH within a broad pH range of 2-12, surpassing the performance observed with other oxygen flow rates. Moreover, under this specific condition, the film exhibited excellent stability, with a minimal drift rate of 0.14 mV/h at pH 7 and a low hysteresis voltage of 1.8 mV during a pH cycle of 7 â†’ 4→7 â†’ 10→7. Given the critical role of epinephrine in mammalian central nervous and hormone systems, monitoring its levels is essential for assessing human health. To facilitate the detection of epinephrine, we utilized the carboxyl group of 4-formylphenylboronic acid to enable a reaction with the amino group of the 3-aminopropyltriethoxysilane-coated InZnSnO film. Through optimization, the resulting InZnSnO-based flexible sensor displayed a broad and well-defined linear relationship within the concentration range of 10-7 to 0.1 µM. In practical applications, this sensor proved effective in analyzing epinephrine in human serum, showcasing notable selectivity, stability, and reproducibility. The promising outcomes of this study underscore the potential for future applications, leveraging the advantages of electrochemical sensors, including affordability, rapid response, and user-friendly operation.

Unique clinical and electrophysiological features in the peripheral nerve system in patients with sialidosis - a case series study.

BACKGROUND: To investigate the peripheral nervous system involvement in S sialidosis with typical features of myoclonus, seizure, and giant waves in somatosensory evoked potentials suggesting hyperexcitability in the central nervous system. METHODS: The clinical presentation of patients with genetically confirmed sialidosis was recorded. Neurophysiological studies, including nerve conduction studies (NCSs), F-wave studies, and needle electromyography (EMG), were performed on these patients. RESULTS: Six patients (M/F: 2:4) were recruited. In addition to the classical presentation, intermittent painful paresthesia was noted in four patients, and three of whom reported it as the earliest symptom. In the NCSs, one patient had reduced compound muscle action potential amplitudes in the right ulnar nerve, while another patient had prolonged distal motor latency in the bilateral tibial and peroneal nerves. Prolonged F-wave latency (83.3%), repeater F-waves (50%), and neurogenic polyphasic waves in EMG (in 2 out of 3 examined patients) were also noted. Interestingly, a very late response was noted in the F-wave study of all patients, probably indicating lesions involving the proximal peripheral nerve or spinal cord. CONCLUSION: In addition to the central nervous system, the peripheral nervous system is also involved in sialidosis, with corresponding clinical symptoms. Further study on these phenomena is indicated.

Implication of acute tubular injury in minimal change nephrotic syndrome.

While acute tubular injury (ATI) is known to occur in a significant number of minimal change disease (MCD) nephrotic syndrome cases with acute kidney injury (AKI), the clinical significance is not certain, and AKI may also occur without ATI. This study aimed to evaluate whether the severity of AKI defined by Kidney Disease Improving Global Outcomes (KDIGO) criteria correlated with the presence or severity of ATI in a series of adult patients with MCD. We also looked at whether time to remission of nephrotic syndrome (NS) with treatment correlated with the presence of ATI in those with and without AKI. We excluded patients with secondary MCD. Of 61 patients, 20 had AKI (33%). ATI was significantly more likely to occur in those with AKI than in those without AKI (60 vs. 24%). Overall, the severity of AKI did not clearly correspond with the severity of ATI. Remission rates at 4 weeks were lowest (25%) in those with both AKI and ATI, while they were highest (100%) in those with neither AKI nor ATI. Patients with AKI but no ATI and those with no AKI but having ATI were intermediate in remission rates and similar to each other (60 and 62%, respectively). The time to remission in the group of those without AKI was significantly longer in those with ATI than in those without (p = 0.0027), but the numerical difference in remission did not reach statistical significance in the smaller group of AKI patients. Patients with ATI were older and more often male than those without ATI. It appears that having ATI may predict a slower remission rate in MCD though the reason for this is unclear. The different demographics of those with ATI may also play a role.

Enantioselective control in chiral crystallization of ethylenediamine sulfate using optical trapping with circularly polarized laser beams.

In this study, we conducted successful experiments on ethylenediamine sulfate (EDS), an organic compound, to investigate its enantioselectivity in chiral crystallization. We employed optical trapping with circularly polarized laser beams, using a continuous wave laser at 1064 nm. By focusing the laser at the air-solution interface of a heavy water-saturated EDS solution, the formation of sub-micrometer-sized chiral EDS crystals was verified. Two generated enantiomorphs (d-crystal and l-crystal) were identified by the rotating analyzer method. The enantioselectivity in the chiral crystallization of EDS was assessed through 30 to 60 times experiments conducted under various conditions of laser powers and polarization modes, utilizing the count of generated crystals for each enantiomorph in the evaluation. Circularly polarized lasers at a specific power created an imbalance in the generation probability of the enantiomorphs, resulting in crystal enantiomeric excess values of 23% and -30%. The enantioselectivity mechanism was explored from two perspectives: refractive index differences of two enantiomorphs and 3D helical optical forces. Study of the thermodynamic mechanism was insufficient to explain the outcomes. Conversely, the 3D helical optical force mechanism revealed that the forces acting on EDS clusters in solution induced helical fluid motion, driving EDS nucleation, with the helicity of fluid motion determining the crystal's chirality. This approach will present new insights into chirality in industrial and research fields, with potential applications in regard to improving optical resolution and addressing the origin of homochirality.

Predicting the therapeutic response to valproic acid in childhood absence epilepsy through electroencephalogram analysis using machine learning.

Childhood absence epilepsy (CAE) is a common type of idiopathic generalized epilepsy, manifesting as daily multiple absence seizures. Although seizures in most patients can be adequately controlled with first-line antiseizure medication (ASM), approximately 25 % of patients respond poorly to first-line ASM. In addition, an accurate method for predicting first-line medication responsiveness is lacking. We used the quantitative electroencephalogram (QEEG) features of patients with CAE along with machine learning to predict the therapeutic effects of valproic acid in this population. We enrolled 25 patients with CAE from multiple medical centers. Twelve patients who required additional medication for seizure control or who were shifted to another ASM and 13 patients who achieved seizure freedom with valproic acid within 6 months served as the nonresponder and responder groups. Using machine learning, we analyzed the interictal background EEG data without epileptiform discharge before ASM. The following features were analyzed: EEG frequency bands, Hjorth parameters, detrended fluctuation analysis, Higuchi fractal dimension, Lempel-Ziv complexity (LZC), Petrosian fractal dimension, and sample entropy (SE). We applied leave-one-out cross-validation with support vector machine, K-nearest neighbor (KNN), random forest, decision tree, Ada boost, and extreme gradient boosting, and we tested the performance of these models. The responders had significantly higher alpha band power and lower delta band power than the nonresponders. The Hjorth mobility, LZC, and SE values in the temporal, parietal, and occipital lobes were higher in the responders than in the nonresponders. Hjorth complexity was higher in the nonresponders than in the responders in almost all the brain regions, except for the leads FP1 and FP2. Using KNN classification with theta band power in the temporal lobe yielded optimal performance, with sensitivity of 92.31 %, specificity of 76.92 %, accuracy of 84.62 %, and area under the curve of 88.46 %.We used various EEG features along with machine learning to accurately predict whether patients with CAE would respond to valproic acid. Our method could provide valuable assistance for pediatric neurologists in selecting suitable ASM.

Proliferation and Differentiation Potential of Bone Marrow-Derived Mesenchymal Stem Cells From Children With Polydactyly and Adults With Basal Joint Arthritis.

This study compared the proliferation and differentiation potential of bone marrow-derived mesenchymal stem cells (BMSCs) derived from infants with polydactyly and adults with basal joint arthritis. The proliferation rate of adult and infant BMSCs was determined by the cell number changes and doubling times. The γH2AX immunofluorescence staining, age-related gene expression, senescence-associated ß-galactosidase (SA-ß-gal) staining were analyzed to determine the senescence state of adult and infant BMSCs. The expression levels of superoxide dismutases (SODs) and genes associated with various types of differentiation were measured using Real-Time Quantitative Polymerase Chain Reaction (RT-qPCR). Differentiation levels were evaluated through histochemical and immunohistochemical staining. The results showed that infant BMSCs had a significantly higher increase in cell numbers and faster doubling times compared with adult BMSCs. Infant BMSCs at late stages exhibited reduced γH2AX expression and SA-ß-gal staining, indicating lower levels of senescence. The expression levels of senescence-related genes (p16, p21, and p53) in infant BMSCs were also lower than in adult BMSCs. In addition, infant BMSCs demonstrated higher antioxidative ability with elevated expression of SOD1, SOD2, and SOD3 compared with adult BMSCs. In terms of differentiation potential, infant BMSCs outperformed adult BMSCs in chondrogenesis, as indicated by higher expression levels of chondrogenic genes (SOX9, COL2, and COL10) and positive immunohistochemical staining. Moreover, differentiated cells derived from infant BMSCs exhibited significantly higher expression levels of osteogenic, tenogenic, hepatogenic, and neurogenic genes compared with those derived from adult BMSCs. Histochemical and immunofluorescence staining confirmed these findings. However, adult BMSCs showed lower adipogenic differentiation potential compared with infant BMSCs. Overall, infant BMSCs demonstrated superior characteristics, including higher proliferation rates, enhanced antioxidative activity, and greater differentiation potential into various lineages. They also exhibited reduced cellular senescence. These findings, within the context of cellular differentiation, suggest potential implications for the use of allogeneic BMSC transplantation, emphasizing the need for further in vivo investigation.

Unraveling the Role of miR-200b-3p in Attention-Deficit/Hyperactivity Disorder (ADHD) and Its Therapeutic Potential in Spontaneously Hypertensive Rats (SHR).

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder in children with unknown etiology. Impaired learning ability was commonly reported in ADHD patients and has been associated with dopamine uptake in the striatum of an animal model. Another evidence also indicated that micro-RNA (miR)-200b-3p is associated with learning ability in various animal models. However, the association between miR-200b-3p and ADHD-related symptoms remains unclear. Therefore, the current study investigated the role of miR-200b-3p in ADHD-related symptoms such as inattention and striatal inflammatory cytokines. To verify the influence of miR-200b-3p in ADHD-related symptoms, striatal stereotaxic injection of miR-200b-3p antagomir (AT) was performed on spontaneously hypertensive rats (SHR). The antioxidant activity and expressions of miR-200b-3p, slit guidance ligand 2 (Slit2), and inflammatory cytokines in the striatum of SHR were measured using quantitative real-time polymerase chain reaction (RT-qPCR), immunohistochemistry (IHC), immunoblotting, and enzyme-linked immunosorbent assay (ELISA). The spontaneous alternation of SHR was tested using a three-arm Y-shaped maze. The administration of miR-200b-3p AT or taurine significantly decreased striatal tumor necrosis factor (TNF)-α, interleukin (IL)-1ß, and IL-6 in SHR, along with increased super-oxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and significantly higher spontaneous alternation. In this paper, we show that miR-200b-3p AT and taurine alleviates ADHD-related symptoms in SHR. These findings provide insights into ADHD's molecular basis and suggest miR-200b-3p as a potential therapeutic target. Concurrently, this study also suggests broad implications for treating neurodevelopmental disorders affecting learning activity such as ADHD.

Depression and anxiety among patients treated for bladder cancer: examining clinical, demographic, and psychosocial predictors.

INTRODUCTION AND OBJECTIVE: The significant impact of bladder cancer and treatment on patient health related quality of life (HRQoL) and emotional wellbeing has been documented. Increasing evidence from cancer research emphasizes the importance of examining patients supportive care needs and received social support as factors that could influence their emotional adjustment. The purpose of the study was to assess the demographic and clinical predictors of depression and anxiety among bladder cancer patients and its associations with patient reported supportive care needs and perceived availability of social support. METHODS: A cross-sectional design was used to investigate the study questions. Bladder cancer patients were recruited from the Bladder Cancer Advocacy Network (BCAN) to complete a questionnaire that included the Hospital Anxiety and Depression Scale (HADS), bladder cancer patient need survey (BCNAS-32), and the social provisions scale (SPS). The inclusion criteria restricted our sample to include bladder cancer patients who were English speakers, aged 18-85 years, and were able and willing to provide informed consent. Patients who had metastatic disease, cancer recurrence, or other primary cancers at the time of assessment were excluded from the study. RESULTS: Participants included 159 bladder cancer patients. The mean age was 62±9.4 years and 51% were male. Almost two-thirds (62%) of patients reported a diagnosis of muscle invasive bladder cancer (MIBC), 25% patient reported clinically significant levels of anxiety, 17% reported clinically significant levels of depression, and 13% and 17% reported abnormal borderline abnormal levels for anxiety and depression, respectively. Univariate regression analyses revealed significant associations between HADS total score, HADS depression and anxiety subscales, patient age, physical functioning/daily living needs, sexuality needs, and perceived social support with higher total scores, anxiety, and depression scores associated with younger age, higher unmet needs, and lower levels of social support. Multivariate regression analyses, showed similar findings confirming the associations depicted by the univariate regression analyses. CONCLUSIONS: Bladder cancer patients experience significant levels of depression and anxiety and these levels are associated with patient age, supportive care unmet needs and lack of social support. Patient focused interventions could be tailored to address these issues with the goal to improve patient HRQoL and emotional adjustment.

Late-onset symptomatic hyperprolactinemia in 6-pyruvoyl-tetrahydropterin synthase deficiency.

BACKGROUND: Tetrahydrobiopterin (BH4) deficiency caused by 6-pyruvoyl-tetrahydropterin synthase (PTPS) deficiency is a rare disorder that is one of the major causes of hyperphenylalaninemia in Taiwan. METHODS: In this study, we reviewed the clinical courses of 12 adolescent and adult patients (7 females and 5 males) with PTPS deficiency. RESULTS: The patients were treated shortly after diagnosis through newborn screening with a combination of BH4, levodopa/carbidopa, and 5-OH-tryptophan. Their plasma phenylalanine and tyrosine levels were well controlled, and their prolactin levels were also decreased after treatment. However, their prolactin levels gradually rose as they grew into puberty, and at a current age of 27.5 [interquartile range (IQR 7.9)] years, five of the 12 patients had either highly elevated prolactin levels (> 100 ng/mL in one male patient, normal reference values, male < 11 ng/mL, female < 17 ng/mL) or symptoms, including irregular menstruation, amenorrhea, and breast swelling (in four female patients). The dosage of levodopa in these five patients (14.3 (IQR 3.0) mg/kg/day) was slightly higher than that in the other patients (p = 0.05). Magnetic resonance imaging studies did not reveal an increase in the size of the anterior pituitary gland, although a Rathke cleft cyst was found in one patient. Two patients received cabergoline treatment, which promptly lowered prolactin levels and relieved symptoms. CONCLUSIONS: Hyperprolactinemia is common in female patients with PTPS deficiency, especially after puberty. A long-acting dopamine agonist, such as cabergoline, may be a necessary adjunctive treatment for most patients with BH4 deficiency.

Acupuncture Reduces Severity of Hot Flashes in Breast Cancer: A Randomized Single-Blind Trial.

This study evaluated the effectiveness of traditional Chinese medicine-based therapeutic acupuncture (TA) in reducing the severity of hot flashes (HFs) in breast cancer patients and compared the effectiveness of TA to "sham" placebo acupuncture (SA). Subjects experiencing more than 10 episodes of HF/week were randomly assigned to TA or SA. The response was assessed by the Menopause-specific Quality of Life (MenQoL) scale, scoring the subject's perception of the severity of HFs. HFs were scored at baseline, after treatment, and 1-month follow-up. A total of 54 subjects enrolled (28 TA and 26 SA). Seven women withdrew from the study. A hot flash diary documented the number of HFs a subject experienced. Analysis included 47 subjects (27 TA and 20 SA). A statistically significant response in HF scores was noted in the TA group compared with the SA group (P = .0064.) On average HF scores dropped by 1.89 with TA, and only 0.16 with SA. At follow-up, TA subjects had a sustained response. TA is effective in reducing the intensity and severity of HF. With SA, no relative response/change in HF scores was noted. Larger studies and longer follow-up to assess durability of response to TA are needed.

Adherence to risk-reducing salpingo-oophorectomy guidelines among gynecologic oncologists compared to general gynecologists.

BACKGROUND: Risk-reducing bilateral salpingo-oophorectomy reduces mortality from high-grade serous carcinoma in patients with hereditary breast and ovarian cancer associated gene mutations. Ideal surgical management includes 5 steps outlined in 2005 by the Society of Gynecologic Oncology and the American College of Obstetricians and Gynecologists. In addition, it is recommended that pathologic examination include serial sectioning of specimens. In practice, risk-reducing salpingo-oophorectomy is performed by both gynecologic oncologists and general gynecologists. To ensure optimal detection of occult malignancy, standardized adherence to outlined guidelines is necessary. OBJECTIVE: This study aimed to evaluate the adherence to optimal surgical and pathologic examination guidelines and to compare the rate of occult malignancy at the time of surgery between 2 provider types. STUDY DESIGN: Institutional review board exemption was obtained. A retrospective review of patients undergoing risk-reducing bilateral salpingo-oophorectomy without hysterectomy from October 1, 2015, to December 31, 2020, at 3 sites within a healthcare system was conducted. The inclusion criteria included age ≥18 years and a documented indication for surgery being a mutation in BRCA1 or BRCA2 or a strong family history of breast and/or ovarian cancer. Compliance with 5 surgical steps and pathologic specimen preparation was based on medical record documentation. Multivariable logistic regression was used to determine differences in adherence between provider groups and surgical and pathologic examination guidelines. A P value of <.025 was considered statistically significant for the 2 primary outcomes after Bonferroni correction was applied to adjust for multiple comparisons. RESULTS: A total of 185 patients were included. Among the 96 cases performed by gynecologic oncologists, 69 (72%) performed all 5 steps of surgery, 22 (23%) performed 4 steps, 5 (5%) performed 3 steps, and none performed 1 or 2 steps. Among the 89 cases performed by general gynecologists, 4 (5%) performed all 5 steps, 33 (37%) performed 4 steps, 38 (43%) performed 3 steps, 13 (15%) performed 2 steps, and 1 (1%) performed 1 step. Gynecologic oncologists were more likely to document adherence to all 5 recommended surgical steps in their surgical dictation (odds ratio, 54.3; 95% confidence interval, 18.1-162.7; P<.0001). Among the 96 cases documented by gynecologic oncologists, 41 (43%) had serial sectioning of all specimens performed, compared with 23 of 89 cases (26%) performed by general gynecologists. No difference in adherence to pathologic guidelines was identified between the 2 provider groups (P=.0489; note: P value of >.025). Overall, 5 patients (2.70%) had occult malignancy diagnosed at the time of risk-reducing surgery, with all surgeries performed by general gynecologists. CONCLUSION: Our results demonstrated greater compliance with surgical guidelines for risk-reducing bilateral salpingo-oophorectomy in gynecologic oncologists than in general gynecologists. No considerable difference was determined between the 2 provider types in adherence to pathologic guidelines. Our findings demonstrated a need for institution-wide protocol education and implementation of standardized nomenclature to ensure provider adherence to evidence-based guidelines.

Uniportal versus multiportal nonintubated thoracoscopic anatomical resection for lung cancer: A propensity-matched analysis.

BACKGROUND/PURPOSE: No studies have compared between uniportal and multiportal nonintubated thoracoscopic anatomical resection for non-small cell lung cancer (NSCLC). We aimed to compare short- and long-term postoperative outcomes concerning these two methods. METHODS: Our retrospective dataset comprised patients with NSCLC who underwent uniportal or multiportal nonintubated thoracoscopic anatomical resection between January 2011 and December 2019. The primary outcome was recurrence-free survival. Propensity scores were matched according to age, sex, body mass index, pulmonary function, tumor size, cancer stage, and surgical method. RESULTS: In total, 1130 such patients underwent nonintubated video-assisted thoracoscopic surgery (VATS), and 490 consecutive patients with stage I-III NSCLC underwent nonintubated anatomical resection, including lobectomy and segmentectomy (uniportal, n = 158 [32.3%]; multiportal, n = 331 [67.7%]). The uniportal group had fewer dissected lymph nodes and lymph node stations. In paired group analysis, the uniportal group had shorter operation durations (99.8 vs. 138.2 min; P < 0.001), lower intensive care unit (ICU) admission rates and ICU admission intervals (7.0% vs. 27.8%; P < 0.001), and shorter postoperative hospital stays (4.1 days vs. 5.2 days; P < 0.001). The most common postoperative complication was prolonged air leaks. No surgical mortality was observed. The multiportal group had higher complication rates for grades ≥ II NSCLC; however, this difference was not significant (4.4% vs. 1.3%, respectively; P = 0.09). CONCLUSION: Nonintubated uniportal VATS for anatomical resection had better results for some perioperative outcomes than multiportal VATS. Oncological outcomes such as recurrence-free and overall survival remained uncompromised, despite fewer dissected lymph nodes.

Objective diagnosis of ADHD through movement analysis by using a smart chair with piezoelectric material.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is the most common neuropsychiatric disorder in schoolchildren. ADHD diagnoses are generally made based on criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. The diagnosis is made clinically based on observation and information provided by parents and teachers, which is highly subjective and can lead to disparate results. Considering that hyperactivity is one of the main symptoms of ADHD, the inaccuracy of ADHD diagnosis based on subjective criteria necessitates the identification of a method to objectively diagnose ADHD. METHODS: In this study, a medical chair containing a piezoelectric material was applied to objectively analyze movements of patients with ADHD, which were compared with those of patients without ADHD. This study enrolled 62 patients-31 patients with ADHD and 31 patients without ADHD. During the clinical evaluation, participants' movements were recorded by the piezoelectric material for analysis. The variance, zero-crossing rate, and high energy rate of movements were subsequently analyzed. RESULTS: The results revealed that the variance, zero-crossing rate, and high energy rate were significantly higher in patients with ADHD than in those without ADHD. Classification performance was excellent in both groups, with the area under the curve as high as 98.00%. CONCLUSION: Our findings suggest that the use of a smart chair equipped with piezoelectric material is an objective and potentially useful method for supporting the diagnosis of ADHD.

Effect of access site choice on inferior vena cava filter angulation and outcomes.

BACKGROUND: In the present study, we compared the outcomes of inferior vena cava (IVC) filter placement between the femoral vein (FV) and internal jugular (IJ) vein access sites. METHODS: We performed a retrospective study using the Vascular Quality Initiative database to assess patients who had undergone IVC filter placement from 2013 to 2019. The patients were placed into two groups according to the access site location: FV and IJ vein. The FV group included patients with access via the right and left FVs and other leg veins, and the IJ group included patients with access via the right or left IJ vein. The primary outcome was the rate of filter angulation. The secondary outcomes included access site complications such as deep vein thrombosis, hematoma, and bleeding requiring transfusion. RESULTS: Of 13,221 patients, 8214 (63%) had undergone IVC filter placement via FV access and 4789 (37%) via IJ access. The remaining 218 patients had had an unknown access site or were excluded. Within the IJ group, 4696 (98.0%) had undergone access via the right IJ and 93 (2%) via the left IJ. Within the FV (common femoral, femoral, or other infrainguinal veins) group, 7007 (85.3%) had undergone access via the right FV and 1207 (14.6%) via the left FV. The mean patient age was 63 ± 15.9 years, the mean body mass index was 30.9 ± 9.60 kg/m2, and 6788 of the patients were men (52.0%). The most common indication for filter placement was a contraindication to anticoagulation because of a recent or active bleeding episode (30%), followed by planned surgery (22%), new deep vein thrombosis/pulmonary embolism (7%), fall risk (5%), and trauma (4%). Infrarenal filters had been placed in 97.9% of the patients. Univariate analysis identified body mass index and suprarenal placement as independent risk factors for angulation. The final multivariate analysis showed a significant increase in angulation (0.9% vs 0.34%; odds ratio, 1.46; 95% confidence interval, 1.02-2.11; P = .04) and increased access site complications (0.25% vs 0.07%; odds ratio, 2.068; 95% confidence interval, 1.01-4.23; P = .048) in the FV access group. No significant correlation between the access site and retrieval rate was found (P = .9270). CONCLUSIONS: Placement of IVC filters via IJ access showed a lower rate of filter angulation in the IVC and fewer access site complications compared with FV access.

EEG Abnormalities and Their Radiographic Correlates in a COVID-19 Inpatient Cohort.

Background and Objectives: To identify the prevalence of EEG abnormalities in patients with coronavirus disease 2019 (COVID-19) with neurologic changes, their associated neuroimaging abnormalities, and rates of mortality. Methods: A retrospective case series of 192 adult COVID-19-positive inpatients with EEG performed between March and June 2020 at 4 hospitals: 161 undergoing continuous, 24 routine, and 7 reduced montage EEG. Study indication, epilepsy history, intubation status, administration of sedatives or antiseizure medications (ASMs), metabolic abnormalities, neuroimaging pathology associated with epileptiform abnormalities, and in-hospital mortality were analyzed. Results: EEG indications included encephalopathy (54.7%), seizure (18.2%), coma (17.2%), focal deficit (5.2%), and abnormal movements (4.6%). Epileptiform abnormalities occurred in 39.6% of patients: focal intermittent epileptiform discharges in 25.0%, lateralized periodic discharges in 6.3%, and generalized periodic discharges in 19.3%. Seizures were recorded in 8 patients, 3 with status epilepticus. ASM administration, epilepsy history, and older age were associated with epileptiform abnormalities. Only 26.3% of patients presented with any epileptiform abnormality, 37.5% with electrographic seizures, and 25.7% patients with clinical seizures had known epilepsy. Background findings included generalized slowing (88.5%), focal slowing (15.6%), burst suppression (3.6%), attenuation (3.1%), and normal EEG (3.1%). Neuroimaging pathology was identified in 67.1% of patients with epileptiform abnormalities, over two-thirds acute. In-hospital mortality was 39.5% for patients with epileptiform abnormalities and 36.2% for those without. Risk factors for mortality were coma and ventilator support at time of EEG. Discussion: This article highlights the range of EEG abnormalities frequently associated with acute neuroimaging abnormalities in COVID-19. Mortality rates were high, particularly for patients in coma requiring mechanical ventilation. These findings may guide the prognosis and management of patients with COVID-19 and neurologic changes.

Prognostic factors for functional recovery in children with moderate to severe acute disseminated encephalomyelitis.

BACKGROUND: Acute disseminated encephalomyelitis (ADEM) is an immune-mediated encephalopathy with heterogeneous disease courses. However, clinical characteristics for a prognostication of functional recovery from acute episodes of ADEM remain limited. The study aims to characterize the clinical presentations and neuroimaging findings of children with poor functional recoveries from acute episodes of moderate to severe ADEM. METHODS: The multicenter retrospective cohort study included children under 18 years of age who presented with moderate to severe ADEM (modified Rankin Scale [mRS] ≥ 3 at nadir) from 2002 to 2019. Children were assigned to a good recovery group (mRS ≤ 2) and a poor recovery group (mRS ≥ 3) after mean 4.3 months of follow-up. The clinical presentations and the distribution of brain lesions on magnetic resonance imaging were compared between the two groups by the t-test for numerical variables and Fisher's exact test for categorical variables. Analyses of logistic regression were conducted and significant variables in the multivariate model were examined by the receiver operating characteristic curve for the prediction of functional recovery. RESULTS: Among the 73 children with moderate to severe ADEM, 56 (77%) had good functional recoveries and 17 (23%) showed poor functional recoveries. Children with poor recoveries had a lower rate of prodromal headache (12% vs. 39%, p = 0.04), and presented with higher proportions of dystonia (29% vs. 9%, p = 0.046), myoclonus (24% vs. 2%, p = 0.009), and cerebellar lesions on neuroimages (59% vs. 23%, p = 0.01). The multivariate analyses identified that a lack of prodromal headache (OR 0.1, 95% CI 0.005 - 0.7, p = 0.06) and the presentations of myoclonus (OR 21.6, 95% CI 1.7 - 874, p = 0.04) and cerebellar lesions (OR 4.8, 95% CI 1.3 - 19.9, p = 0.02) were associated with poor functional recoveries. These three factors could prognosticate poor outcomes in children with moderate to severe ADEM (area under the receiver operating characteristic curve 0.80, 95% CI 0.68 - 0.93, p = 0.0002). CONCLUSION: Nearly one-fourth of children with moderate to severe ADEM had a poor functional recovery from acute episodes, who were characterized by a lack of prodromal headache, the presentation of myoclonus, and the neuroimaging finding of cerebellar lesions. The clinical variables associated with poor functional recoveries could assist in the planning of immunotherapies during hospitalization for a better outcome in moderate to severe ADEM.

Non-Intubated Versus Intubated Video-Assisted Thoracic Surgery in Patients Aged 75 Years and Older: A Propensity Matching Study.

Introduction: In most developed countries, lung cancer is associated with the highest mortality rate among all cancers. The number of elderly patients with lung cancer is increasing, reflecting the global increase in aging population. Patients with impaired lung or cardiac function are at a high risk during intubated general anesthesia, which may preclude them from surgical lung cancer treatment. We evaluated the safety and survival of non-intubated video-assisted thoracoscopic surgery (VATS) versus those of intubated thoracoscopic surgery for surgical resection for lung cancer in older patients. Methods: Patients aged ≥75 years who underwent non-intubated and intubated VATS resection with pathologically confirmed non-small cell lung cancer, using a combination of thoracic epidural anesthesia or intercostal nerve block and intra-thoracic vagal block with target-controlled sedation, from January 2011 to December 2019 were included. Ultimately, 79 non-intubated patients were matched to 158 patients based on age, sex, body mass index, family history, comorbidity index, pulmonary function (forced expiratory volume in one second/ forced vital capacity [%]), and disease stage. The endpoints were overall survival and recurrence progression survival. Results: All patients had malignant lung lesions. Data regarding conversion data and the postoperative result were collected. Both groups had comparable preoperative demographic and cancer staging profiles. The anesthetic duration in the non-intubated group was shorter than that in the intubated group, which showed a significantly higher mean number of lymph nodes harvested (intubated vs non-intubated, 8.3 vs. 6.4) and lymph stations dissected (3.0 vs. 2.6). Intensive care unit (ICU) admission rate and postoperative ICU stay were significantly longer in the intubated group. The complication rate was higher and hospital stay were longer in the intubated group, but these differences were not significant (12% vs. 7.6%; p = .07, respectively). Conclusions: In the elderly, non-intubated thoracoscopic surgery provides similar survival results as the intubated approach, although fewer lymph nodes are harvested. Non-intubated surgery may serve as an alternative to intubated general anesthesia in managing lung cancer in carefully selected elderly patients with a high risk of impaired pulmonary and cardiac function.

Treatment Effectiveness and Tolerability of Long-term Adjuvant First- and Second-Generation Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor at Different Doses in Patients With Stage IIA-IIIB Epidermal Growth Factor Receptor-Mutated Lung Adenocarcinoma: A Retrospective Study.

Introduction: For patients with epidermal growth factor receptor (EGFR)-mutated lung cancer who undergo surgery, adjuvant tyrosine kinase inhibitor (TKI) therapy other than osimertinib is an alternative option. We aimed to discuss the long-term safety and efficacy of TKI treatment in real-world data. Methods: From January 2011 to May 2020, patients with stage II-III EGFR-mutated adenocarcinoma who underwent cancer resection surgery at a single center were enrolled. The primary endpoint was disease relapse, and the secondary endpoint was overall survival. In total, 30 patients were included in the study. In our study, all patients underwent complete resection using video-assisted thoracoscopic surgery. The patients were divided into a dose interruption (prolonged interval use) group and non-dose adjustment group. Results: The patients' pathological stages were II-III. The initial EGFR TKIs were mostly gefitinib (n = 25, 83%), and others were erlotinib (n = 3, 10%) and afatinib (n = 2, 6%). The mean disease-free survival (DFS) was 53.3 months. The 2- and 5-year DFS rate was 90.0 and 73.3%, respectively. The median TKI treatment duration in this study was 44.5 months (range, 6-133 months), which was the longest in the literature review. Of these patients, nine had dose interruption. We compared the two groups and found no treatment differences between them. There were no significant side effect potentials between both groups. Conclusion: To our knowledge, this study provides the longest experience of TKI in patients with resected EGFR mutations and also provided a dose reduction strategy (prolonged medication interval) for patients who had intolerable side effects.
