Establishment and Validation of a Nomogram for Identifying False Positives in Xpert MTB/RIF Rifampicin Resistance Test.

Purpose: This study aimed to establish and validate a diagnostic nomogram for identifying false positives in the Xpert MTB/RIF (Xpert) for detection of rifampicin resistance (RIF-R). Patients and Methods: In this retrospective study, we collected basic patient characteristics and various clinical information from the electronic medical record database. Patients were randomly divided into training and validation groups in a 7:3 ratio. LASSO regression was used to screen variables and construct a diagnostic nomogram. The ROC curve, calibration curve, and decision curve analysis (DCA) were used to evaluate the performance of the nomogram. Results: A total of 384 patients were included in the study, with 268 and 116 patients in the training and validation cohorts, respectively. Finally, probe mutations and probe delay were identified as the independent influencing factors. Using the mutation of probe E as a reference, probes A or C (OR = 51.07, P<0.001), probe D (OR = 7.48, P<0.001), and multiple probes (OR = 4.42, P=0.029) were identified as factors influencing false positives in Xpert for detection of RIF-R. Taking probe delay ΔCT <4 as a reference, ΔCT (4-5.9) (OR = 17.06, P=0.005) and ΔCT (6-7.9) (OR = 36.67, P<0.001) were noted to be the factors influencing false positives in Xpert for detection of RIF-R. Based on these two variables, we constructed a diagnostic nomogram. The area under the curve of the nomogram model was 0.847 and 0.850 for the training and validation groups, respectively. The calibration curves were consistent. The DCA revealed that the model achieved the greatest net benefit when the threshold probability was set between 6% and 71% in the training cohort and 6% and 70% in the validation cohort. Conclusion: The nomogram constructed can identify false positives in Xpert for detection of RIF-R and provides basis for clinicians to formulate diagnosis and treatment plans.

Is language impaired in Spanish-speaking children with autism spectrum disorder level 1?

The current diagnostic criteria for the autism spectrum disorder (ASD) include the possibility to specify concomitant language difficulties. Purpose: Our main aim was to explore whether children with ASD-Level 1 (ASD-L1) present difficulties in the acquisition of structural language, as little work has been done in this regard so far. As a secondary aim we evaluated the degree to which the potential language impairment in ASD is directly associated with their social communication deficits or it represents a distinct deficit. Methods: To further clarify the nature and characteristics of putative language difficulties in ASD-L1, we evaluated language skills in 89 children and preadolescents diagnosed with ASD-L1, and a group of typically developing participants (TD). All of them were between 8 and 13 years old and had similar socioeconomic backgrounds. Results: Children with ASD-L1 obtained lower scores than those in TD group in repeating sentences, in finding the semantic relationships between words, and in applying word structure rules (morphology). Congruently, the core language standard score was lower in the ASD-L1 group, and the proportion of language delay was significantly higher in the ASD-L1 group than in the control group. Conclusion: Language scores were associated with autistic traits; thus, language performance in ASD-L1 is closely related to autistic symptoms. These results are discussed according to the literature on linguistic deficits in ASD-L1 and their relations with phonological working memory.

Delay learning based on temporal coding in Spiking Neural Networks.

Spiking Neural Networks (SNNs) hold great potential for mimicking the brain's efficient processing of information. Although biological evidence suggests that precise spike timing is crucial for effective information encoding, contemporary SNN research mainly concentrates on adjusting connection weights. In this work, we introduce Delay Learning based on Temporal Coding (DLTC), an innovative approach that integrates delay learning with a temporal coding strategy to optimize spike timing in SNNs. DLTC utilizes a learnable delay shift, which assigns varying levels of importance to different informational elements. This is complemented by an adjustable threshold that regulates firing times, allowing for earlier or later neuron activation as needed. We have tested DLTC's effectiveness in various contexts, including vision and auditory classification tasks, where it consistently outperformed traditional weight-only SNNs. The results indicate that DLTC achieves remarkable improvements in accuracy and computational efficiency, marking a step forward in advancing SNNs towards real-world applications. Our codes are accessible at https://github.com/sunpengfei1122/DLTC.

Pediatrician Knowledge of Early Intervention Process as Contributor to Disparities in Management of Development Delay.

INTRODUCTION: Lack of knowledge of Early Intervention (EI) is a barrier to developmental delay (DD) management. We aimed to examine the feasibility of measuring pediatricians' knowledge of EI, determine the distribution of EI knowledge, and determine factors associated with increased EI knowledge. METHODS: We conducted an exploratory cross-sectional study with a convenience sample from a local American Academy of Pediatrics chapter to administer a survey with 10 multiple-choice questions regarding the EI referral process, evaluation process, eligibility criteria and fee structure. Our outcome variable was a composite score of these 10 multiple-choice questions, Total Knowledge Score (TKS). Our predictor variables included physician characteristics (i.e., years of experience, percentage of patients seen with private insurance, receipt of EI training in the last 5 years) and practice characteristics (i.e., medical home status). RESULTS: Our sample consisted of a total of 194 pediatric residents/attendings. Multivariable regression demonstrated seeing ≥ 50% patients who were privately insured, increased experience, and receiving training in the last 5 years were associated with higher TKS. DISCUSSION: We were able to quantitatively evaluate physician's knowledge of EI and demonstrated that seeing a majority of privately insured patients, having more experience, and having received formal EI training in the last 5 years were associated with higher EI knowledge. This disproportionate distribution of EI knowledge has the potential to contribute to disparities in the management of DD. This may indicate that medical institutions, where physicians see a small percent of privately insured patients, need to hire more experienced physicians, and provide routine EI training.

Cerebral Small Vessel Disease is Associated with Prehospital Delay in Acute Ischemic Stroke.

AIM: To determine whether the severity of cerebral small vessel disease (SVD) is associated with prehospital delay in acute ischemic stroke. METHODS: Consecutive patients with ischemic stroke were included in this study. We evaluated the SVD burden using the total SVD score. Patients were divided into 2 groups: onset-to-door time within 4.5 hours (early arrival group) and onset-to-door time over 4.5 hours (delayed arrival group). First, we assessed whether the total SVD score was related to prehospital delay using a logistic regression analysis. Second, we assessed which item of the score was independently associated with delays. Finally, we determined whether the item had a linear association with the delay. RESULTS: Of the 2,112 screened patients, 1,754 were enrolled in the study (1,253 males [71%]; median age, 69 years). There were 1,105 patients (63%) in the delayed arrival group. The total SVD score was independently associated with delay (OR 1.11, 95% CI 1.01-1.21, p=0.025). Among the 4 items of the score, only enlarged perivascular spaces (EPVS) in the basal ganglia was independently associated with delay (OR 1.37, 95% CI 1.05-1.80, p=0.022). A linear trend was observed between EPVS grade and delay with reference to EPVS grade 0-1 (EPVS grade 2: OR 1.22, 95% CI 0.92-1.62, p=0.170, EPVS grade 3: OR 1.69, 95% CI 1.20-2.38, p=0.002, EPVS grade 4: OR 2.17, 95% CI 1.37-3.44, p=0.001). CONCLUSIONS: Prehospital delay in acute ischemic stroke could be associated with the severity of SVD, particularly EPVS in the basal ganglia.

Chinese-modified MIND Diet and subjective well­being in adults aged 60 years or older in China: a national community-based cohort study.

OBJECTIVE: Observing the dietary principles of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet has exhibited an association with a diminished occurrence of diverse ailments, enhanced mental well-being, and extended longevity. Nevertheless, current literature is deficient in terms of investigating the link between the MIND diet and subjective well-being (SWB) specifically in older adults. Hence, this study endeavors to examine the correlation between adhering to a Chinese-modified Mediterranean-DASH Intervention for Neurodegenerative Delay (cMIND) diet and SWB in the older Chinese adults, taking into account the unique dietary attributes of the Chinese population. METHODS: Using data from the latest four waves of the Chinese Longitudinal Healthy Longevity Survey. Multiple linear regression and multinomial ordered logistic regression were employed to examine the relationship between the duration of adherence to cMIND diet and SWB in Chinese older adults. RESULTS: The results indicated a significant association between the duration of adherence to cMIND diet and SWB (1 ∼ 6 years: B = 0.907, 95%CI = 0.508 ∼ 1.307, P < 0.001; 7 ∼ 9 years: B = 1.286, 95%CI = 0.767 ∼ 1.805, P < 0.001; 10 years and above: B = 2.320, 95%CI = 1.677 ∼ 2.963, P < 0.001). The longer the duration of adherence to cMIND diet, the higher the scores for life satisfaction (B = 0.184, 95%CI = 0.110 ∼ 0.259; B = 0.312, 95%CI = 0.217 ∼ 0.407; B = 0.321, 95%CI = 0.193 ∼ 0.448), positive affect (B = 0.434, 95%CI = 0.209 ∼ 0.658; B = 0.701, 95%CI = 0.400 ∼ 1.003; B = 1.167, 95%CI = 0.775 ∼ 1.559), and negative affect (B = 0.289, 95%CI = 0.078 ∼ 0.500; B = 0.832, 95%CI = 0.479 ∼ 1.185), suggesting a higher SWB score. Sensitivity analysis further supports our findings. CONCLUSION: Considering the poor knowledge, attitudes, and behaviors related to diet among Chinese adults, especially older adults, it is imperative to implement dietary policies that promote SWB in older adults to enhance their happiness in later life.

2D spatiotemporal passive cavitation imaging and evaluation during ultrasound thrombolysis based on diagnostic ultrasound platform.

Acoustic cavitation plays a critical role in various biomedical applications. However, uncontrolled cavitation can lead to undesired damage to healthy tissues. Therefore, real-time monitoring and quantitative evaluation of cavitation dynamics is essential for understanding underlying mechanisms and optimizing ultrasound treatment efficiency and safety. The current research addressed the limitations of traditionally used cavitation detection methods by developing introduced an adaptive time-division multiplexing passive cavitation imaging (PCI) system integrated into a commercial diagnostic ultrasound platform. This new method combined real-time cavitation monitoring with B-mode imaging, allowing for simultaneous visualization of treatment progress and 2D quantitative evaluation of cavitation dosage within targeted area. An improved delay-and-sum (DAS) algorithm, optimized with a minimum variance (MV) beamformer, is utilized to minimize the side lobe effect and improve the axial resolution typically associated with PCI. In additional to visualize and quantitatively assess the cavitation activities generated under varied acoustic pressures and microbubble concentrations, this system was specifically applied to perform 2D cavitation evaluation for ultrasound thrombolysis mediated by different solutions, e.g., saline, nanodiamond (ND) and nitrogen-annealed nanodiamond (N-AND). This research aims to bridge the gap between laboratory-based research systems and real-time spatiotemporal cavitation evaluation demands in practical uses. Results indicate that this improved 2D cavitation monitoring and evaluation system could offer a useful tool for comprehensive evaluating cavitation-mediated effects (e.g., ultrasound thrombolysis), providing valuable insights into in-depth understanding of cavitation mechanisms and optimization of cavitation applications.

Automatic characterization of capillary flow profile of liquid samples on µTADs based on capacitance measurement.

Capillary flow profile of liquid samples in porous media is closely related to the important properties of liquid samples, including the viscosity and the surface energy. Therefore, capillary flow profile can be used as an index to differentiate liquid samples with different properties. Fast and automatic characterization of capillary flow profile of liquid samples is necessary. In this work, we develop a portable and economical capacitance acquisition system (CASY) to easily obtain the capillary flow profile of liquid samples on microfluidic thread-based analytical devices (µTADs) by measuring the capacitance during the capillary flow. At first, we validate the accuracy of this method by comparing with the traditional method by video analysis in obtaining the capillary flow profiles in µTADs of cotton threads or glass fiber threads. Then we use it to differentiate liquid samples with different viscosity (mixture of water and glycerol). In addition, capillary flow profile on µTADs with chemical valves (chitosan or sucrose) can also be obtained on this device. Lastly, we show the potential of this device in measurement of hematocrit (HCT) of whole blood samples. This device can be used to catalog liquid biological samples with different properties in point-of-care diagnostics in the near future.

Association between patient and system delays and in-hospital mortality in primary PCI for STEMI: Findings from a large, nationwide inpatients sample.

PURPOSE: System delay is associated with mortality in patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI). However, the influence of patient delay has been relatively overlooked. We aimed to evaluate the influence of patient and system delays on STEMI patients undergoing primary PCI in China. METHODS: STEMI patients registered at the Nationwide Chinese Cardiovascular Association Database-Chest Pain Center from January 2017 to September 2021 were screened. The exposures were total ischemic time (TIT), system delay and patient delay. The primary outcome was in-hospital mortality. RESULTS: Among 458,260 patients from 2,529 centers, median TIT, system delay and patient delay were 4.1, 1.5 and 2.1 hours, respectively. The adjusted odds ratio of in-hospital mortality increased by 2.2% (odds ratio [OR], 1.022, 95% confidence interval [CI], 1.017-1.027), 2.3% (1.023, 1.006-1.040) and 2.2% (1.022, 1.017-1.027) for every one-hour increase in TIT, system delay and patient delay, respectively. CONCLUSIONS: Patient delay demonstrated a comparable impact to system delay on in-hospital mortality among STEMI patients undergoing primary PCI. Widespread primary PCI-capable center, improved awareness about myocardial infarction and regional transfer system are essential to shorten patient delay.

A novel STAG1 variant associated with congenital clubfoot and microphthalmia: A case report.

The cohesin protein complex plays a vital role in various cellular processes such as sister chromatid cohesion, chromosome condensation, DNA repair, and transcriptional regulation. It is constituted by SMC1, SMC3, RAD21, STAG1/STAG2 subunits, and several regulatory proteins. Pathogenic variants in these components cause cohesinopathies, with common clinical features including facial dysmorphism, delayed growth, developmental delay, and limb anomalies. Pathogenic variants in the STAG1 contribute to an emerging syndromic developmental disorder with only 21 reported cases in the literature. We describe a 3-year-old girl presenting with congenital bilateral clubfoot and unilateral microphthalmia-clinical manifestations not previously reported in the literature. Whole exome sequencing revealed a novel de novo nonsense variant (c.1183C>T, p.(Arg395*)) in the STAG1, expanding the clinical and molecular spectrum of STAG1-related cohesinopathy. This patient's unique phenotype highlights the clinical diversity within cohesinopathies, emphasizing their relevance in cases of developmental delay and dysmorphic features. Further studies, including genotype-phenotype correlation analyses and functional investigations, are essential for enhancing our understanding of STAG1-related cohesinopathy.

MASTering systemic mastocytosis: Lessons learned from a large patient cohort.

Background: Systemic mastocytosis (SM), a rare condition affecting about 32,000 individuals in the United States, is often misdiagnosed or underdiagnosed owing to its nonspecific symptoms and the need for invasive biopsies. Objective: Our aim was to identify, classify, and characterize the natural history of patients with SM. Methods: In a retrospective cohort study, administrative data from a large managed care organization was used to identify patients with confirmed SM, based on World Health Organization criteria. Demographic data, delay to diagnosis, disease progression, and health care resource utilization were examined. Results: Of 116 patients with confirmed SM, 77% had indolent SM, 2% had smoldering SM, 12% had SM with associated hematologic neoplasm, 9% had aggressive SM, and none had mast cell leukemia. In all, 5 patients were misclassified as having a less advanced SM subtype initially and 3 were completely undiagnosed (missed diagnosis). The average delay to diagnosis of SM was 58.3 plus or minus 73.1 months. In all, 18% of patients progressed from a nonadvanced form of SM (indolent or smoldering SM) to an advanced form of SM (aggressive SM, SM with associated hematologic neoplasm, or mast cell leukemia) over an average of 88.3 plus or minus 82.7 months. Patients with SM had increased health care utilization, including increases in their numbers of hospital admissions, emergency room visits, urgent care visits, and specialty provider visits, after diagnosis versus before. Conclusions: Rare diseases such as SM would benefit from increased understanding and awareness to improve diagnostic accuracy. Prospective studies are needed to better characterize this patient population and determine the type of follow-up needed to recognize advanced forms of SM so that appropriate treatment can be implemented.

Proximal 4p Deletion Syndrome in an Infant With Multiple Systemic Anomalies.

BACKGROUND: Contiguous gene deletion in the short arm of chromosome 4 is linked to various neurodevelopmental disorders. METHODS: In this study, we conducted peripheral blood chromosome G-banding karyotyping and whole-exome sequencing (WES) on a proband presenting with anal atresia, global developmental delay, lymphocytosis, and other multisystem anomalies. Additionally, chromosome G-banding karyotyping was also carried out on the proband's parents and brother. RESULTS: The 7-month-old proband was found to have a 26.738 Mb 4p15.33-p14 deletion as identified by chromosome G-banding karyotyping and WES. CONCLUSION: We identified a patient with proximal 4p deletion syndrome by karyotype and WES analysis, which might explain some of his phenotypes. Our research enhances clinicians' knowledge of this rare condition, and offers valuable genetic counseling to the affected family. Further research is necessary to identify the causative gene or critical region associated with proximal 4p deletion syndrome.

Exploring influential factors in childhood vaccine delays in Riyadh, Saudi Arabia.

Introduction: Infectious diseases present a substantial worldwide health challenge, yet vaccines have played a crucial role in significantly decreasing illness rates. Despite their effectiveness, global vaccination coverage stands at 85%, leaving a considerable number of infants without routine immunization. Our study seeks to examine the occurrence of delayed primary vaccination and the factors influencing it in Riyadh, Saudi Arabia addressing a critical void in current research. Methodology: A cross-sectional investigation was carried out in the primary care facilities of the first health cluster in Riyadh, Saudi Arabia. Information was gathered utilizing a well-structured questionnaire, modified from a prior study. The study encompassed children aged two years and younger, accompanied by their parents who brought their vaccination cards for the visit. Non-probability convenience sampling was employed for data collection. Subsequently, the data underwent thorough cleaning in Excel (Microsoft Excel) and was subjected to analysis using IBM SPSS 29 (IBM SPSS Statistics 29). Results: The study involved 402 participants, primarily over 12 months old, with a balanced gender distribution. Noteworthy findings indicate a 20.9% prevalence of childhood vaccine delays, with reasons such as high-grade fever (33.3%) and travel (26.2%). Significant associations were found in children aged 6-12 months (25.8%, P = 0.039), families with over four children (31%, P = 0.010), perceptions of vaccine harm (50.0%, P = 0.013), and acknowledgment of neglect (96.4%, P = 0.001). Conclusion: The research illuminates the complex factors influencing childhood vaccine delays in Saudi Arabia. Stressing the significance of personalized interventions, it underscores the necessity to tackle challenges specific to age, parental perspectives, and access issues for improved vaccination outcomes.

Effectiveness of training on primary care nurses' knowledge and screening practice in identification of children at risk for developmental delay: An Indian perspective.

Background: In India, overall, 1.5-19.8% of the children were found to be developmentally delayed. The evaluation of development in young children and health professionals' early referrals for diagnostic assessment will accelerate appropriate early intervention as early as possible. Nurses can screen the children and help the parents by providing the necessary information and support. Aim: To train the primary care nurses on developmental screening and early identification of developmental delay (DD) in children and find the effectiveness of the same. Objectives of the study: To evaluate the effectiveness of the training program on the knowledge and screening practice of the nurses towards the identification of children at risk for DD and to find out the relationship between nurses' knowledge and screening practice. Methods and Materials: A quasi-experimental, one-group pretest, post-test design was adopted among 69 nurses, who were providing child care services and working in the selected government hospitals in Bengaluru, South India. Nurses' knowledge and screening practice in identifying children at risk for DD were assessed before and after the training. SPSS package 21.00 version was used to analyse the descriptive and inferential statistics. Results: The training program was effective in the enhancement of primary care nurses' knowledge and screening practice in the identification of DDs in under-five children. Conclusion: The findings of this study concluded that developmental screening can be performed by nurses with suitable training programs. The training program played a significant role in the enhancement of nurses' knowledge and screening practice in the identification of DDs in under-five children.

Simultaneous closure of a perilymphatic fistula and placement of cochlear implant in a case of complex inner ear malformation.

Key Clinical Message: In young infants, under the age of one-year, cochlear malformation with profound hearing loss complicated by a perilymphatic fistula (PLF), presents a serious clinical challenge, warranting immediate audiological and surgical intervention. Timely PLF detection and closure, along with an early CI can significantly improve the prognosis of such patients and helps them in achieving their maximum hearing and developmental potential, in the long term. Abstract: Inner ear malformation (IEM) with incomplete partition and cystic cochlea is mostly accompanied by profound hearing loss. It gets further complicated with other malformations such as a perilymphatic fistula (PLF). This case concerns an 8-month-old child cochlear malformation and profound hearing loss. Surgical intervention identified a PLF at the stapedial footplate, which was successfully closed. The surgery also included the placement of a cochlear implant (CI) in the right ear, via the round window. The left ear was equipped with hearing aids, with persistent hearing thresholds at 70-80 db. At the age of 6 years, the child showed a good hearing outcome with the CI, with only moderate speech delay. Cochlear malformation accompanied by a perilymphatic leakage warrants immediate surgical closure of the PLF, to minimize the risk of bacterial meningitis. Wherever possible, the feasibility of a CI should be explored in such cases and a CI should be placed for treatment of hearing loss. Audiological and speech outcomes may vary with the use of the CI, especially in cases of IEM. However, an early CI coupled with timely PLF detection and closure can help children with profound hearing loss, in achieving their maximum hearing and developmental potential, in the long run.

Delay Discounting and BMI in Hypertensives: Serial Mediations of Self-Efficacy, Physical Activity and Sedentary Behavior.

Objective: Our study aimed to examine the association between delay discounting (DD) and body mass index (BMI) in individuals with hypertension. Additionally, we sought to explore and compare the potential mediating effects of self-efficacy, physical activity and sedentary behavior in this association. Methods: A cross-sectional survey was conducted in two cities in the Jiangsu province of China, specifically Nanjing and Yangzhou, from March to June 2023. A total of 972 hypertensive patients completed the questionnaire (M age = 64.7 years, SD age = 8.2 years, 54.2% female). Participants engaged in a money choice experiment on computers, provided their height and weight, and completed the International Physical Activity Questionnaire-Short Form (IPAQ-SF) and General Self-Efficacy Scale (GSES). The experimental program was generated using the programming software E-Prime version 2.0. Multiple hierarchical regression analysis was conducted to identify potential covariates. Two serial mediation models were conducted using PROCESS macro 4.1 in SPSS 27.0. Physical activity and sedentary behavior were designated as M2 to investigate and contrast their respective mediating effects in the association between delay discounting and body mass index. Results: Self-efficacy, physical activity, and sedentary behavior served as mediators in the relationship between delay discounting and BMI. Self-efficacy accounted for 14.9% and 14.3% of the total effect in Models 1 and 2, respectively, while physical activity and sedentary behavior each accounted for 14.9% and 9.5% of the total effect, respectively. The serial mediation effects of self-efficacy and physical activity, as well as self-efficacy and sedentary behavior, were significant (B = 0.01, 95% CI [0.01, 0.02]; B = 0.01, 95% CI [0.002, 0.01]), collectively contributing 2.1% and 2.4% of the total effect. Sedentary behavior played a smaller mediating role compared to physical activity in this association. Conclusion: The results indicated that self-efficacy, physical activity and sedentary behavior could act as mediators in the association between delay discounting and BMI, thus potentially mitigating the risk of obesity in hypertensive individuals.

Perceived Social Support and Health-Related Quality of Life Among Hypertensive Patients: A Latent Profile Analysis and the Role of Delay Discounting and Living Alone.

Background: Improving health-related quality of life (HRQoL) among hypertensive individuals has emerged as a significant public health issue. However, current research has ignored the individual heterogeneity of perceived social support (PSS) among hypertensive patients. The potential mechanism of delay discounting (DD), living alone, and PSS on HRQoL remains unclear, and further exploration is required. Aim: This study aimed to ascertain PSS profiles among hypertensive patients and examine the hypotheses that DD mediates the relationship between PSS and HRQoL and that this mediating process is moderated by living alone in hypertensive patients. Methods: A cross-sectional study was carried out in Jiangsu, China. In total, 1815 hypertensive patients completed socio-demographic and HRQoL questionnaires, a PSS scale, and a DD task. Data analyses included a latent profile analysis, χ2-test, Spearman correlation analysis, and PROCESS macro for regression analysis. Results: Four potential PSS profiles were identified: lowest (3.2%), moderate-low (26.6%), moderate-high (42.4%), and highest (27.8%). DD mediated the association between PSS and HRQoL. The first half of this mediating process was moderated by living alone. Conclusion: Our findings indicated that PSS, DD, and living alone significantly influence the HRQoL of individuals with hypertension. Healthcare professionals should consider variations in PSS among hypertensive patients and implement interventions to reduce DD by enhancing PSS, in order to improve the HRQoL of this population.

Presumed Perinatal Ischemic Left Middle Cerebral Artery Stroke With Cerebral Palsy, Developmental Delay, and Epilepsy: A Case Report.

The perinatal period is a high risk for ischemic events to occur leading to lifelong morbidity. Various patterns of ischemic injury to the fetal and neonatal brain have been studied depending on gestational age as well as the degree of hypoxia/ischemia. We present a case of presumed perinatal ischemic left middle cerebral artery stroke diagnosed by magnetic resonance imaging (MRI) in a child with global developmental delay, cerebral palsy, and epilepsy. Interestingly, the typical features of middle cerebral artery stroke are often not present in perinatal strokes, and hence these are not imaged perinatally. Since studies and research into neuroplasticity and neuromodulation are current topics of interest and several research studies are being conducted, we wish to add this case to the available scientific literature.

A Scoping Review of Intervention Implementation for Self-Care Skills among Children with Developmental Delay.

Difficulties with self-care skills are frequently observed in children with developmental delays. Given the scarcity of robust evidence backing self-care interventions for this group, this scoping review is designed to aggregate existing literature on the implementation of such interventions. Therefore, this scoping review aims to collate literature on the nature of self-care intervention implementation to increase understanding of the current practice and inform future research directions. This scoping review endeavoured to explore the body of literature concerning the existence of self-care interventions and their implementation strategies in children who have developmental delays. Relevant studies were identified by searching through the following databases: Web of Science (W0S), Scopus, ASEAN Citation Index (ACI), CINAHL EBSCO and PubMed. Six types of interventions using various approaches were identified. Occupational therapists mainly manage intervention providers with multidisciplinary co-facilitator and parents' involvement. Whilst session information varied, some evidence suggests that at least 30 min per session, minimum once per week up to twice per week, ranging from 10 to 23 sessions, may be sufficient. Intervention plans should be tailored to each child's unique needs, taking into account the variety of available interventions. Collaboration among occupational therapists, parents, educators and health professionals in home programmes enhances self-care intervention outcomes. These results are set to inform future research and practice, paving the way for enhanced support and improved outcomes for children with developmental delays.

Willingness to wait outperforms delay discounting in predicting drinking severity.

Alcohol misuse ranks among the leading causes of preventable death worldwide. Therefore, discovering measures that can predict hazardous drinking is critical. The delay discounting paradigm-which assesses relative preference for immediate rewards over larger, later rewards-has frequently been used as a proxy for impulsive choice, but it does not capture how long someone is willing to wait for delayed rewards when the arrival time is uncertain. In contrast, a newer willingness-to-wait task measures how long someone is willing to wait for a delayed reward of uncertain timing before giving up. We hypothesized that performance in this willingness-to-wait task would be associated with drinking severity and that this task may even outperform delay discounting as a predictor of drinking severity. We pooled data from multiple studies of mostly college-aged adult participants. Drinking severity was assessed with the Alcohol Use Disorders Identification Test. Willingness to wait under temporal uncertainty, but not delay discounting, was associated with severity of alcohol problems among participants who drank (n = 212). Individuals engaging in hazardous drinking were less willing to wait for rewards when delays were unknown than were individuals with low-risk drinking habits. Thus, willingness to wait under temporal uncertainty may be an important predictor of problematic drinking.
