OBJECTIVES
Acute pancreatitis(AP) is a common digestive tract disease, often accompanied by severe metabolic disorders, but there are no specific markers and treatment methods, and the potential metabolic pathways behind it remain to be explored.
METHODS
Establish mild acute pancreatitis and severe acute pancreatitis models in rats and intervene with antioxidant NAC. Analyze serum oxidative stress indicators and pathological changes in pancreatic tissue. In addition, non-targeted metabolomics analysis of serum differential metabolites between groups was conducted based on the LC/MS system.
RESULTS
The pathological score of the model group rats increased, and the levels of oxidative stress factors ROS and MDA significantly increased, while the activity of the antioxidant enzyme SOD decreased. After NAC intervention, oxidative stress damage in rats was alleviated. Non-targeted metabolomics experiments suggest significant differences in serum metabolic profiles among different groups of rats.
CONCLUSION
Metabolomics results show that the obtained differential metabolites are expected to become serum biomarkers for AP.

INTRODUCTION
Sensorineural hearing loss (SNHL) can arise from a diverse range of congenital and acquired factors. Detecting it early is pivotal for nurturing speech, language, and cognitive development in children with SNHL. In our study, we utilized synthetic magnetic resonance imaging (SyMRI) to assess alterations in both gray and white matter within the brains of children affected by SNHL.
METHODS
The study encompassed both children diagnosed with SNHL and a control group of children with normal hearing {1.5-month-olds ( = 52) and 3-month-olds ( = 78)}. Participants were categorized based on their auditory brainstem response (ABR) threshold, delineated into normal, mild, moderate, and severe subgroups.Clinical parameters were included and assessed the correlation with SNHL. Quantitative analysis of brain morphology was conducted using SyMRI scans, yielding data on brain segmentation and relaxation time.Through both univariate and multivariate analyses, independent factors predictive of SNHL were identified. The efficacy of the prediction model was evaluated using receiver operating characteristic (ROC) curves, with visualization facilitated through the utilization of a nomogram. It's important to note that due to the constraints of our research, we worked with a relatively small sample size.
RESULTS
Neonatal hyperbilirubinemia (NH) and children with inner ear malformation (IEM) were associated with the onset of SNHL both at 1.5 and 3-month groups. At 3-month group, the moderate and severe subgroups exhibited elevated quantitative T1 values in the inferior colliculus (IC), lateral lemniscus (LL), and middle cerebellar peduncle (MCP) compared to the normal group. Additionally, WMV, WMF, MYF, and MYV were significantly reduced relative to the normal group. Additionally, SNHL-children with IEM had high T1 values in IC, and LL and reduced WMV, WMF, MYV and MYF values as compared with SNHL-children without IEM at 3-month group. LL-T1 and WMF were independent risk factors associated with SNHL. Consequently, a prediction model was devised based on LL-T1 and WMF. ROC for training set, validation set and external set were 0.865, 0.806, and 0.736, respectively.
CONCLUSION
The integration of T1 quantitative values and brain volume segmentation offers a valuable tool for tracking brain development in children affected by SNHL and assessing the progression of the condition's severity.

Meta-Analysis Review
BACKGROUND
Inhaled corticosteroid (ICS) therapy has been demonstrated to reduce the risk of COPD exacerbations. It should only be prescribed to COPD patients who are not adequately controlled by dual long-acting bronchodilator therapy and who have ≥2 exacerbations per year and a blood eosinophil count ≥300cells/µL. ICS therapy is widely prescribed outside guidelines to COPD patients, making ICS withdrawal an important consideration. This systematic review aims to provide an up-to-date analysis of the effect of ICS withdrawal on exacerbation frequency, change in lung function (FEV) and to determine the proportion of COPD patients who resume ICS therapy following withdrawal.
METHODS
Randomised controlled trials (RCTs) and observational studies which compared ICS withdrawal with ICS continuation treatment were included. Cochrane Central, Web of Science, CINHAL, Embase and OVID Medline were searched. Risk of bias was assessed using the Cochrane RoB2 tool and the Newcastle-Ottawa Scale. Quality assessment of RCTs was conducted using GRADE. Meta-analysis of post-hoc analyses of RCTs of ICS withdrawal, stratified by blood eosinophil count (BEC), was undertaken.
RESULTS
Ten RCTs (6642 patients randomised) and 6 observational studies (160,029 patients) were included in the results. When ICS was withdrawn and long-acting bronchodilator therapy was maintained, there was no consistent difference in exacerbation frequency or lung function change between the ICS withdrawal and continuation trial arms. The evidence for these effects was of moderate quality. There was insufficient evidence to draw a firm conclusion on the proportion of patients who resumed ICS therapy following withdrawal (estimated range 12-93% of the participants).
DISCUSSION
Withdrawal of ICS therapy from patients with COPD is safe and feasible but should be accompanied by maintenance of bronchodilation therapy for optimal outcomes.

As the number of pacemaker insertions increases to manage numerous cardiac arrhythmias, the number of complications is also increasing as a result. More common complications such as infection and lead displacement are routinely discussed with patients before they undergo the procedure. However rare complications such as superior vena cava syndrome are not discussed during the consenting period. But they do occur, as seen in this case of a 69-year-old male. This fit and active man had a right-sided dual-chamber pacemaker inserted due to sinus node disease and presented 5 years later with symptoms suggestive of superior vena cava obstruction (SVCO). Despite anticoagulation and before surgical intervention could be performed, the patient developed a right-sided chylothorax which was drained. An autologous pericardial patch repair of the SVC and a thrombectomy of SVC clots was subsequently performed. This was only partially successful and the SVCO recurred. A low fatty chain diet was initiated to manage the chylothorax, which remains stable. This rare complication has left the patient with a small pleural effusion and chronic pleural thickening. They can still exercise with mild breathlessness. The management of such a complication, which requires the input of many specialists, is challenging and often does not completely resolve all symptoms. For this reason, superior vena cava obstruction should be considered as a risk during the consenting procedure for a pacemaker insertion.

Bardet-Biedl syndrome (BBS) is a rare genetic disorder characterized by retinitis pigmentosa, polydactyly, type 2 diabetes mellitus, and obesity. This case report presents a 19-year-old male from Palestine with BBS, exhibiting delayed diagnosis and variable phenotypic expression. The patient had familial BBS history and presented with obesity, type 2 diabetes mellitus, retinitis pigmentosa, and cryptorchidism. Genetic analysis identified heterozygous missense variants in the gene, yet additional genetic factors may contribute to the phenotype. Renal abnormalities included kidney shrinkage and mild hydronephrosis. Management of this patient involves a multidisciplinary approach with lifestyle modifications, surgical interventions, and supportive care. Early diagnosis, genetic counseling, and regular follow-up are crucial for improving outcomes in BBS. This report highlights diagnostic and therapeutic challenges and underscores the need for further research on this complex disorder.

Alzheimer's disease (AD) and AD-related dementias (AD/ADRD) are a group of progressive neurodegenerative diseases. The progression of AD can be conceptualized as a continuum in which patients progress from normal cognition to preclinical AD (i.e., no symptoms but biological changes in the brain) to mild cognitive impairment (MCI) due to AD (i.e., mild symptoms but not interfere with daily activities), followed by increasing severity of dementia due to AD. Early detection and prediction models for the transition of MCI to AD/ADRD are needed, and efforts have been made to build predictions of MCI conversion to AD/ADRD. However, most existing studies developing such prediction models did not consider the competing risks of death, which may result in biased risk estimates. In this study, we aim to develop a prediction model for AD/ADRD among patients with MCI considering the competing risks of death using a semi-competing risk approach.

Reductions in default mode (DMN) connectivity strength have been reported in posttraumatic stress disorder (PTSD). However, the specificity of DMN connectivity deficits in PTSD compared to major depressive disorder (MDD), and the sensitivity of these alterations to acute stressors are not yet known. 52 participants with a primary diagnosis of PTSD ( = 28) or MDD ( = 24) completed resting-state functional magnetic resonance imaging immediately before and after a mild affective stressor. A 2 × 2 design was conducted to determine the effects of group, stress, and group*stress on DMN connectivity strength. Exploratory analyses were completed to identify the brain region(s) underlying the DMN alterations. There was significant group*stress interaction ( = 0.03), reflecting stress-induced reduction in DMN strength in PTSD ( = 0.02), but not MDD ( = 0.50). Nodal exploration of connectivity strength in the DMN identified regions of the ventromedial prefrontal cortex and the precuneus potentially contributing to DMN connectivity deficits. The findings indicate the possibility of distinct, disease-specific, patterns of connectivity strength reduction in the DMN in PTSD, especially following an experimental stressor. The identified dynamic shift in functional connectivity, which was perhaps induced by the stressor task, underscores the potential utility of the DMN connectivity and raises the question whether these disruptions may be inversely affected by antidepressants known to treat both MDD and PTSD psychopathology.

INTRODUCTION
Mild cognitive impairment (MCI) is a stage between health and dementia, with various symptoms including memory, language, and visuospatial impairment. Chiropractic, a manual therapy that seeks to improve the function of the body and spine, has been shown to affect sensorimotor processing, multimodal sensory processing, and mental processing tasks.
METHODS
In this paper, the effect of chiropractic intervention on Electroencephalogram (EEG) signals in patients with mild cognitive impairment was investigated. EEG signals from two groups of patients with mild cognitive impairment ( = 13 people in each group) were recorded pre- and post-control and chiropractic intervention. A comparison of relative power was done with the support vector machine (SVM) method and non-parametric cluster-based permutation test showing the two groups could be separately identified with high accuracy.
RESULTS
The highest accuracy was obtained in beta2 (25-35 Hz) and theta (4-8 Hz) bands. A comparison of different brain areas with the SVM method showed that the intervention had a greater effect on frontal areas. Also, interhemispheric coherence in all regions increased significantly after the intervention. The results of the Wilcoxon test showed that intrahemispheric coherence changes in frontal-occipital, frontal-temporal and right temporal-occipital regions were significantly different in two groups.
DISCUSSION
Comparison of the results obtained from chiropractic intervention and previous studies shows that chiropractic intervention can have a positive effect on MCI disease and using this method may slow down the progression of mild cognitive impairment to Alzheimer's disease.

The vascular endothelial growth factor (VEGF) polymorphism is associated with preeclampsia since its abnormal expression plays an important role in vasculogenesis in placenta formation. Thus, this study is aimed at analyzing the association between VEGF +936C/T polymorphism and the risk of preeclampsia. To assess the causal relationship, a hospital-based cross-sectional analytical study was carried out among 204 Myanmar pregnant women during the period of January 2018-September 2020. For data collection, a pretested, structured questionnaire was used. Blood samples were collected after obtaining consent, and then we studied the extracted gene by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The Statistical Package for Social Sciences version 18.0 was used for data management and analysis. The genotype CT variant among preeclamptic women was more than that of non-preeclamptic women (26.5% vs. 18.6%), but not significant ( = 0.180). The risk of preeclampsia among women with CT genotypes was 1.57 times higher than that of women with CC genotypes (OR (95%CI) = 1.57 (0.81, 3.06), = 0.180). The minor allele frequency of the T allele was 15.2% in preeclamptic women and 9.3% in normal pregnant women. The risk of preeclampsia among T allele carriers is 1.49 times (95%CI = 0.80, 2.77) more than that of C allele carriers ( = 0.211). Among the preeclamptic pregnant women, the frequency of the CT genotype was 26.3% in the severe preeclamptic group and 26.9% in the mild preeclamptic group, while the frequency of the T allele was 13.2% and 13.5%, respectively. The frequency of either CT genotype or T allele was more or less the same in both groups, and there was no association between VEGF C/T polymorphism and the severity of preeclampsia. After logistic regression analysis on VEGF genotype and clinical parameters such as age, maternal body mass index (BMI), and neonatal birth weight, the risk of preeclampsia was 2.1 times higher in pregnant women with CT genotype compared to CC genotype (adjusted OR, 2.1; 95% CI, 0.9-4.5, value -0.057). There was no significant association between VEGF +936C/T polymorphism (rs3025039) and preeclampsia among Myanmar pregnant women. However, the findings of this study highlighted that individuals carrying either the CT genotype or the T allele are at a heightened risk of developing preeclampsia. Furthermore, it suggests a potential impact of the gene on the occurrence of preeclampsia, yet the data lacks sufficient evidence to establish statistical significance.

BACKGROUND
The coronavirus disease 2019 (COVID-19) pandemic outbreak created a challenge to manage the health, especially the mental health of various care providers involved in treating the patients infected with the virus. Previously published literature has shown a significant effect of the pandemic on the psychological health of healthcare workers (HCWs) globally; so, this study aimed to describe the psychological health outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among Indian HCWs.
METHODS
An extensive literature search was conducted in databases including PubMed and Google Scholar. The search was restricted from the COVID-19 outbreak until June 2022. Cross-sectional studies and other studies (telephonic interviews and survey-based studies) reported the prevalence of anxiety and depression among frontline HCWs since the onset of the COVID-19 pandemic. All the studies were critically evaluated by two individual authors in terms of screening and methodological quality evaluation. A total of 16 studies were included in the final meta-analysis.
RESULTS
The prevalence of depression among n = 12231 participants of 14 studies was 0.37 CI 95% [0.28-0.48]; the prevalence of anxiety among n = 9467 participants of 12 studies was 0.39 CI 95% [0.29-0.49]. The results of the overall meta-analysis indicate that 37% and 39% of HCWs in this study experienced mild-to-severe depression and anxiety, respectively. During the COVID-19 pandemic, a significant number of HCWs developed mental health issues, with a reported prevalence of depression (37%) and anxiety (39%).
CONCLUSION
Frontline HCWs' mental health should get full consideration during public health emergencies, screening should be actively conducted, and specific steps should be taken to lower the fear associated with the risk of infections.
