Enhanced levels of fractalkine and HSP60 in cerebrospinal fluid of sporadic amyotrophic lateral sclerosis patients

Amyotrophic Lateral Sclerosis (ALS) is a multifactorial neurodegenerative disorder with a significant contribution of non-cell autonomous mechanisms to motor neuronal degeneration. Amongst a plethora of molecules, fractalkine (C-X3-C motif chemokine ligand 1), and Heat Shock Protein 60 (HSP60), are key modulators of microglial activation. The contribution of these molecules in Sporadic ALS (SALS) remains unexplored. To investigate this, fractalkine levels were estimated in Cerebrospinal fluid (CSF) of SALS patients (ALS-CSF; n = 44) by Enzyme-linked Immunosorbent Assay (ELISA) and correlated with clinical parameters including disease severity and duration. CSF HSP60 levels were estimated by Western blotting (ALS-CSF; n = 19). Also, CSF levels of Chitotriosidase-1 (CHIT-1), a microglia-specific neuroinflammatory molecule, were measured and its association, if any, with fractalkine and HSP60 was investigated. Both fractalkine and HSP60 levels were significantly elevated in ALS-CSF. Similar to our earlier observation, CHIT-1 levels were also upregulated. Fractalkine showed a moderate negative correlation with the ALS-Functional Rating Scale (ALSFRS) score indicating its significant rise in mild cases which plateaued in cases with high disease severity. However, no obvious correlation was found between fractalkine, HSP60, and CHIT-1. Our study hints that high fractalkine levels in mild cases might be conferring neuroprotection by combating microglial activation and highlights its importance as a novel therapeutic target for SALS. On the other hand, significantly enhanced levels of HSP60, a pro-inflammatory molecule, hint towards its role in accentuating microgliosis, although, it doesn’t act synergistically with CHIT-1. Our study suggests that fractalkine and HSP60 act independently of CHIT-1 to suppress and accentuate neuroinflammation, respectively.

A Joy-Stick Assistant Three-Dimensional Modified Technique of Minimally Invasive Surgery for Mild or Moderate Hallux Valgus.

Minimally invasive surgery (MIS) such as minimally invasive chevron osteotomy and Akin osteotomy (MICA) has become popular in the treatment of hallux valgus. However, how to correct three-dimensional deformities in hallux valgus effectively and simply in MICA is still difficult. Special equipment is required in MICA as has been reported before. It is meaningful and necessary to reduce the reliance on special equipment in MICA. From January 2021 to July 2022, patients with mild or moderate hallux valgus were treated with a joy-stick assistant three-dimensional modified technique (Joy-stick 3D technique) of MIS. VAS, AOFAS Hallux MTP-IP scores, hallux valgus angle (HVA), intermetatarsal angle (IMA), and distal metatarsal articular angle (DMAA) were measured pre- and postoperatively at the last follow-up of at least 6 months. Scores and radiologic angles were compared using paired sample t-test. A total of 36 cases were included. HVA, IMA, and DMAA were (22.3 ± 6.1)°, (14.0 ± 3.2)°, and (8.9 ± 3.2)° preoperatively, and decreased to (7.0 ± 1.8)°, (3.7 ± 1.0)°, and (3.3 ± 1.1)° postoperatively. VAS decreased from 4.3 ± 1.7 to 0.7 ± 0.7. AOFAS Hallux MTP-IP scores improved from 68.6 ± 7.6 to 92.9 ± 6.1. Comparing mild and moderate cases, though HVA, IMA, and DMAA were significantly different preoperatively, the angles became statistically similar after surgery. A joy-stick assistant three-dimensional modified technique is proposed to control the three-dimensional position of the metatarsal head and to reduce dependence on special tools. Mild and moderate hallux valgus deformities are effectively corrected using Joy-stick 3D technique.

Mapping Neurophysiological Patterns in Carpal Tunnel Syndrome: Correlations With Tinel's and Phalen's Signs.

Background This study aimed to observe the neurophysiological severity grading of carpel tunnel syndrome (CTS) using nerve conduction studies (NCSs) and the correlation between Tinel's and Phalen's signs. Methodology In this cross-sectional study, 240 patients of CTS were enrolled. NCSs were conducted in 480 hands. Various variables such as distal latency, amplitude, and nerve conduction velocity in both sensory and motor median nerves were recorded. The provocative tests capable of reproducing patients' symptoms such as Phalen's test and Tinel's test were performed on all 480 hands studied. Results Neurophysiological variables were affected in 449 out of 480 hands. Tinel's sign was observed in 59% of cases (265 hands) while Phalen's sign was positive in 37.2% (167 hands) of cases. Severity grading of CTS based on neurophysiological variables resulted in Grade I (mild) in 202 hands, Grade II (mild to moderate) in 56 hands, Grade III (moderate) in 39 hands, and Grade IV (severe) in 152 hands. Provocative tests (Tinel's and Phalen's) used for the diagnosis of CTS were positive in 68 hands (36.66%) and 26 hands (12.8%), respectively, in mild Grade I. However, as the CTS severity grade increased, the provocative test success rate also increased simultaneously. In severe Grade IVCTS, Tinel's and Phalen's tests were positive in 134 (88.1%)hands and 94 (61.8%) hands, respectively. Conclusions This study underscores the unreliability of Tinel's and Phalen's signs as screening methods for CTS severity. With moderate sensitivity and specificity, NCSs are deemed essential for confirming CTS diagnosis and assessing severity, especially in mild cases that might be mistakenly perceived as normal hands by consultants.

Case Series of Endoscopic Papillary Balloon Dilation for Children with Common Bile Duct Stones and a Review of the Literature.

Background: Endoscopic sphincterotomy (EST) has been employed for the endoscopic treatment of common bile duct stones (CBDSs) and has been reported to have a high success rate for stone removal. However, EST is associated with a risk of bleeding, perforation, and sphincter of Oddi function disruption. To avoid these risks, endoscopic papillary balloon dilation (EPBD) is an option for CBDS. Sphincter of Oddi function preservation decreases long-term biliary infection and gallstone recurrence. EPBD may have advantages in children who require a long follow up. However, there have been few reports on pediatric cases, particularly in infants. Methods: From September 2017 to December 2023, we performed EPBD for four pediatric CBDSs. The patients were aged from 5 months to 8 years, including two infants aged 5 and 6 months. Furthermore, we reviewed the stone removal rate and complications of 545 ESTs performed at high-volume centers and 13 EPBD-reported cases in children with CBDSs. Results: CBDSs of all patients who underwent EPBD in our institution were successfully removed. No bleeding or perforation was noted; pancreatitis was observed in three patients. In an analysis of 545 ESTs in children, the stone removal rate was high, ranging from 83% to 100% (mean 96%). The incidence of pancreatitis was 0-9.6% (mean 4.4%), and the grade of pancreatitis was almost mild. The bleeding frequency was 1.3-5.4% (mean 2.7%). With regards to the grade of bleeding, seven cases were mild (64%) and four were moderate (36%). Compared with adults who underwent EST, the frequencies of pancreatitis and bleeding were almost equal in children; however, in children, once bleeding occurs, it has a higher risk of leading to blood transfusion. Stone removal via EPBD in children has a 100% success rate. Pancreatitis was responsible for all complications were related; its frequency was 46% (6/13 patients, including five mild cases and one moderate case), which is higher than that of EST and adult cases who underwent EPBD. In most children with pancreatitis, pancreatic enzyme levels returned to normal within 2-3 days following EPBD, and no severe cases caused by EPBD were reported. Conclusions: CBDS removal via EPBD in children has a high success rate with very low risk of bleeding and perforation. Although pancreatitis frequently occurs, most cases are mild. Sphincter of Oddi function preservation via EPBD is expected to prevent long-term stone recurrence and biliary tract infection, and EPBD is considered to be an effective method for CBDS removal in children.

Analysis of mild and severe neonatal enterovirus infections in a Chinese neonatal tertiary center: a retrospective case-control study.

To compare the clinical characteristics, virus serotype, and outcome in cases of mild and severe enteroviral infection at a tertiary neonatal intensive care unit in China. A retrospective analysis of cases hospitalized between June and August 2019. Samples (stool or throat swabs) were examined using reverse transcription polymerase chain reaction. Positive cases were divided into two groups: mild infection and severe infection. A total of 149 cases were assigned to one of two groups: mild infection (n = 104) and severe infection (n = 45). There were no significant differences between the groups in terms of sex, gestational age, birth weight, mode of delivery, and onset within 7 days. Clinical symptoms in both groups mostly resembled sepsis (fever, rash, poor feeding, and lethargy); however, there were significant variations in concomitant symptoms such as hepatitis, thrombocytopenia, encephalitis, coagulopathy, and myocarditis. Severe cases were more likely to have abnormal complete blood counts, biochemical parameters, and cerebrospinal fluid markers. The predominant serotypes implicated in neonatal enterovirus infections were echoviruses and Coxsackievirus B. Invasive ventilation, intravenous immunoglobulin, vasoactive medications, and blood product transfusions were often required, with high mortality rates among severe cases. We found significant differences between mild and severe cases of neonatal enterovirus infection with respect to complications, laboratory findings, and enterovirus serotypes. It is crucial to exercise caution when newborns exhibit symptoms of sepsis, during an enterovirus outbreak. Anemia, thrombocytopenia, abnormal liver function, and coagulation dysfunction should be monitored closely as they could indicate the presence of a severe enteroviral infection.

A deep learning model based glaucoma detection using retinal images

The retinal illness that causes vision loss frequently on the globe is glaucoma. Hence, the earlier detection of Glaucoma is important. In this article, modified AlexNet deep leaning model is proposed to category the source retinal images into either healthy or Glaucoma through the detection and segmentations of optic disc (OD) and optic cup (OC) regions in retinal pictures. The retinal images are preprocessed and OD region is detected and segmented using circulatory filter. Further, OC regions are detected and segmented using K-means classification algorithm. Then, the segmented OD and OC region are classified and trained by the suggested AlexNet deep leaning model. This model classifies the source retinal image into either healthy or Glaucoma. Finally, performance measures have been estimated in relation to ground truth pictures in regards to accuracy, specificity and sensitivity. These performance measures are contrasted with the other previous Glaucoma detection techniques on publicly accessible retinal image datasets HRF and RIGA. The suggested technique as described in this work achieves 91.6% GDR for mild case and also achieves 100% GDR for severe case on HRF dataset. The suggested method as described in this work achieves 97.7% GDR for mild case and also achieves 100% GDR for severe case on RIGA dataset. AIM: Segmenting the OD and OC areas and classifying the source retinal picture as either healthy or glaucoma-affected. METHODS: The retinal images are preprocessed and OD region is detected and segmented using circulatory filter. Further, OC region is detected and segmented using K-means classification algorithm. Then, the segmented OD and OC region classified are and trained by the suggested AlexNet deep leaning model. RESULTS: The suggested method as described in this work achieves 91.6% GDR for mild case and also achieves 100% GDR for severe case on HRF dataset. The suggested method as described in this work achieves 97.7% GDR for mild case and also achieves 100% GDR for severe case on RIGA dataset. CONCLUSION: This article proposes the modified AlexNet deep learning models for the detections of Glaucoma utilizing retinal images. The OD region is detected using circulatory filter and OC region is detected using k-means classification algorithm. The detected OD and OC regions are utilized to classify the retinal images into either healthy or Glaucoma using the suggested AlexNet model. The proposed method obtains 100% Sey, 93.7% Spy and 96.6% CA on HRF dataset retinal images. The proposed AlexNet method obtains 97.7% Sey, 98% Spy and 97.8% CA on RIGA dataset retinal images. The proposed method stated in this article achieves 91.6% GDR for mild case and also achieves 100% GDR for severe case on HRF dataset. The suggested method as described in this work achieves 97.7% GDR for mild case and also achieves 100% GDR for severe case on RIGA dataset.

Assessing antiviral treatment efficacy and risk factors for severe COVID-19 in kidney transplant recipients during the Omicron subvariant-dominant period: a retrospective study

BackgroundKidney transplant recipients (KTRs) are at risk of severe coronavirus disease 2019 (COVID-19), and even now that Omicron subvariants have become dominant, cases of severe disease are certain to occur. The aims of this retrospective study were to evaluate the efficacy of antiviral treatment for COVID-19 and to identify risk factors for severe disease in KTRs during Omicron subvariant-dominant periods.MethodsA total of 65 KTRs diagnosed with COVID-19 who received antiviral treatment between July 2022 and September 2023 were analyzed. Mild cases received oral molnupiravir (MP) as outpatient therapy, while moderate or worse cases received intravenous remdesivir (RDV) as inpatient therapy. In principle, mycophenolate mofetil was withdrawn and switched to everolimus. We investigated the efficacy of antiviral treatment and compared the clinical parameters of mild/moderate and severe/critical cases to identify risk factors for severe COVID-19.ResultsAmong 65 cases, 49 were mild, 6 were moderate, 9 were severe, and 1 was of critical severity. MP was administered to 57 cases; 49 (86%) improved and 8 (14%) progressed. RDV was administered to 16 cases; 14 (87%) improved and 2 (13%) progressed. Seventeen (26%) cases required hospitalization, and none died. Comparisons of the severe/critical group (n = 10) with the mild/moderate group (n = 55) demonstrated that the severe/critical group had a significantly higher median age (64 vs. 53 years, respectively; p = 0.0252), prevalence of diabetes (70% vs. 22%, respectively; p = 0.0047) and overweight/obesity (40% vs. 11%, respectively; p = 0.0393), as well as a significantly longer median time from symptom onset to initial antiviral therapy (3 days vs. 1 day, respectively; p = 0.0026). Multivariate analysis showed that a longer time from symptom onset to initial antiviral treatment was an independent risk factor for severe COVID-19 (p = 0.0196, odds ratio 1.625, 95% confidence interval 1.081–2.441).ConclusionThese findings suggest that a longer time from symptom onset to initial antiviral treatment is associated with a higher risk of severe COVID-19 in KTRs. Initiating antiviral treatment as early as possible is crucial for preventing severe outcomes; this represents a valuable insight into COVID-19 management in KTRs.

Adaptive feature selection for active trachoma image classification

Trachoma is a neglected tropical eye disease caused by ocular strains of Chlamydia trachomatis, which affects millions of people worldwide. To examine the eye for signs of active trachoma, healthcare providers typically look for clusters of five or more follicles on the conjunctiva of the upper eyelid for the follicular inflammatory trachoma stage. However, it is also possible to find individual follicles scattered throughout the conjunctiva, particularly in mild or early-stage trachoma cases. Additionally, the datasets are photographic images collected in the field that can be high-dimensional and may contain large amounts of redundant information. We propose integrating novel attention-based feature extraction and feature selection techniques to address these challenges. First, we present the Lambda layer within the Convolutional Block Attention Module (L-CBAM) to normalize attention weights and improve the feature extraction process. Second, we introduce an adaptive mechanism, Adaptive Beta Hill Climbing (AβHC) with Social Ski-Driver (SSD), which adjusts the exploration-exploitation trade-off during the search process, allowing for better exploration of the search space and more efficient convergence toward an optimal feature subset. We then use the multilayer perceptron (MLP) classifier to produce final classification results using selected subsets. We evaluated the proposed approach on active trachoma inverted eyelid images and obtained accuracy scores of 93.3% with only 19.7% of the selected features, surpassing many of the algorithms used for comparison. Our proposed method has demonstrated excellent performance compared to recent works utilizing the same datasets.

DYNAMICS OF VASCULAR ENDOTHELIAL GROWTH FACTOR IN HEMORRHAGIC STROKE DEPENDING ON THE DISEASE SEVERITY

Introduction. The results of experimental studies indicate the growth factors, in particular the vascular endothelial growth factor, around the hematoma already at the beginning of hemorrhagic stroke.
 The aim of the study: to find out the features of vascular endothelial growth factor expression in patients with hemorrhagic stroke depending on the disease severity.
 Research metods. 53 patients with hemorrhagic stroke were examined. The control group - 25 people with hypertension without dyscirculatory disorders of cerebral circulation.
 The level of neurological deficit was assessed using the National Institute of Health Stroke Scale (NIHSS).
 Vascular endothelial growth factor (VEGF) in the blood was determined on the 1st, 5th and 21st days of the acute stroke period by enzyme-linked immunosorbent assay (ELISA) (test kits of the company "Biosourse" (USA)). The research results were analyzed by the method of variational statistics using the program "STATISTICA 6.0" (StatSoft, USA).
 Results and discussion. With a mild degree of severity, the content of VEGF in the blood is significantly lower on the 1st and 5th days of the acute period compared to the control group. This may be one of the factors contributing to the development of a hemorrhagic stroke. An increase in VEGF in the first days of the disease can be a marker of the serious condition of patients with hemorrhagic stroke. VEGF levels on the 5th and 21st days are highest in mild cases, and lowest in severe cases. The increased synthesis of VEGF in case of a mild stroke indicates a more adequate response of the endothelium to damage.
 Conclusions. A marker of a mild hemorrhagic stroke can be low VEGF levels in the first days of the disease and their significant increase at the end of the previous period. High VEGF in the blood at the beginning of the disease, and relatively lower indicators (compared to a mild course) at the end of the previous period are associated with the severe condition of patients with hemorrhagic stroke.

Aesthetic and Functional Outcomes of Upper Blepharoplasty Combined with Dacryoadenopexy in Lacrimal Gland Prolapse.

Lacrimal gland prolapse (LGP) is a term used to describe a benign, anterior displacement of the lacrimal gland. If this condition is not properly addressed during upper blepharoplasty, the aesthetic and functional results are less than optimal. This study aimed to report the surgical outcomes of upper blepharoplasty combined with dacryoadenopexy in patients with LGP. We reported an unusual case of severe LGP in a young patient. In addition, we performed a systematic review of the English literature on surgical cases of LGP published between 1973 and 2023. Eligible articles were analyzed for individual patient data (IPD) and aggregate patient data (APD). The primary predictor variable was the surgical technique used for lacrimal gland repositioning/suspension. The primary outcome variable was relapse rate. The bibliographic search retrieved 488 surgical cases of LGP: 12 in IPD, and 476 in APD datasets. The relapse rates in the IPD and APD cohorts were 8.3% (1/12) and 1.2% (6/476), respectively. Within the APD dataset, no significant difference in the relapse rates between dacryoadenopexy via suture suspension and Whitnall's ligament suspension (5/409 and 1/20, respectively; P > 0.05) was observed. Light cauterization of the lacrimal gland capsule and surrounding soft tissues was performed in mild LGP cases (< 4mm prolapse), with a relapse rate of 0% (0/47). Upper blepharoplasty combined with dacryoadenopexy proved to be a safe surgical procedure with very satisfactory aesthetic outcome and minimal relapse rate.

Evaluation of pulmonary imaging data by radiography in children with bronchopulmonary dysplasia

Introduction. According to specialized literature, X-rays are also used in the diagnosis and suspicion of chronic bronchopulmonary disease (bronchopulmonary dysplasia (BPD), in premature children. Material and methods. The study included 105 premature babies who were divided into the study group – premature babies with bronchopulmonary dysplasia (BPD) and the control group – premature babies without BPD. Data were statistically analyzed using Microsoft Excel, MedCalc, SPSS and Contingency Table Analysis as a method of evaluating the performance of a diagnostic test. Results. Radiological changes of discoidal atelectasis type in subjects with BPD were detected in 49.1% in the basic group versus 13.5% in the control group (χ2 = 15.431; p &lt; 0.0001), subsegmental ones 47.2% vs 25.0% (χ2 = 5.586; p = 0.018); pulmonary emphysema areas 62.3% vs 5.8% (χ2 = 37.182; p &lt; 0.0001), opaque fibrosis sectors 50.9% vs 11.5% (χ2 = 18.911; p &lt; 0.0001); signs of pulmonary hypertransparency 47.2% vs 1.9% (χ2 = 28.843; p &lt; 0.0001); microcystic formations 41.5% vs 5.8% (χ2 = 18.482; p &lt; 0.0001). Depending on the severity degrees of BPD, changes such as discoidal atelectasis were noted, in those with mild grade – 50% medium grade – 38.5%, severe grade – 56.3% (χ2 = 16.502; p &lt; 0.001), subsegmental atelectasis 41.7%, vs 38.5% (χ2 = 7.956; p = 0.047), pulmonary emphysema areas 58.3%, vs 38.5%, vs 87.5% (χ2 = 45.138; p &lt; 0.0001); microcystic formations, 33.3%, vs 53.8%, vs 43.8% (χ2 = 20.502; p &lt; 0.0001). Conclusions. The changes recorded on radiological examination in mild, moderate, and severe cases of BPD in premature babies are of the type discoidal atelectasis, areas of emphysema, opaque sectors of fibrosis, pulmonary hypertransparency, microcystic formations.

Measuring disease burden of dominant variants of COVID-19 in Taiwan

ObjectivesThe disability-adjusted life years (DALYs) of COVID-19 have been applied as a time-based measurement to estimate years of life lost due to premature mortality or healthy life lost in different countries. Limited information was found for DALYs among different variants of concern (VOC). MethodsDisease severities based on categories of asymptomatic, mild, moderate, severe, and critical cases were explored among different VOC by analyzing the proportions in confirmed cases. DALY or years of healthy life lost due to disability (YLD)-based annual burdens of COVID-19 on different ages, genders as well as trend analysis were also evaluated for VOC in Taiwan. ResultsDifferent trends were observed in years of life lost due to premature mortality (YLLs) or YLD for various age or gender categories. Disease severity at critical stage had the highest percentage for overall YLDs encompassed from 2020 to 2022. Also, critical-grade cases were found to be predominantly caused by Wild-type, Alpha, and Omicron variants in 2020, 2021, and 2022, respectively. ConclusionPrecautionary measures are also suggested for policy makers to take in specific seasons, age or gender groups based on YLL and YLD analyses.

Association between ambient temperature and genitourinary emergency ambulance dispatches in Japan: A nationwide case-crossover study.

Although the effects of temperature on genitourinary morbidity and mortality have been investigated in several countries, it remains largely unexplored in Japan. We investigated the association between ambient temperature and genitourinary emergency ambulance dispatches (EADs) in Japan and the modifying roles of sex, age, and illness severity. We conducted a time-stratified case-crossover study with conditional quasi-Poisson regression to estimate the association between mean temperature and genitourinary EADs in all prefectures of Japan between 2015 and 2019. A mixed-effects meta-analysis was used to pool the association at the country level. Subgroup analyses were performed to explore differences in associations stratified by sex, age, and illness severity. We found an increased risk of genitourinary EAD associated with higher temperatures. The cumulative relative risk (RR) at the 99th temperature percentile compared with that at the 1st percentile was 1.74 (95% confidence interval (CI) = [1.60, 1.89]). We observed higher heat-related RRs in males (RR = 1.89; 95% CI = [1.73, 2.07]) than females (RR = 1.56; 95% CI = [1.37, 1.76]), and in the younger (RR = 2.13; 95% CI = [1.86, 2.45]) than elderly (RR = 1.39; 95% CI = [1.22, 1.58]). We found a significant association for those with mild or moderate cases (RR = 1.77; 95% CI = [1.62, 1.93]), but not for severe or life-threatening cases (RR = 1.20; 95% CI = [0.80, 1.82]). Our study revealed heat effects on genitourinary EADs in Japan. Men, youth, and mild-moderate illnesses were particularly vulnerable subgroups. These findings underscore the need for preventative measures aimed at mitigating the impact of temperature on genitourinary emergencies.

Perinatal and neurodevelopmental outcomes of fetal isolated ventriculomegaly: a systematic review and meta-analysis.

Isolated fetal ventriculomegaly can have a range of consequences, ranging from mild neurodevelopmental delay to perinatal death; the extent of these consequences often depend on the severity of ventriculomegaly. This systematic review and meta-analysis aims to investigate the impact of the degree of ventricular dilatation on the risk of neurodevelopmental delay and adverse perinatal outcomes in fetuses diagnosed with isolated fetal ventriculomegaly from gestational week 15 onwards. PubMed, Embase, Scopus and the Cochrane Library were searched electronically to identify studies investigating the prognosis of mild and/or severe isolated fetal ventriculomegaly. Articles were included if they reported neurodevelopmental or perinatal outcomes in fetuses prenatally diagnosed with isolated fetal ventriculomegaly from week 15 of gestation and onwards. Studies were excluded if they reported on non-isolated ventriculomegaly (IVM), failed to specify the degree of ventriculomegaly, were non-English papers, animal studies or published outside of the 21-year period of interest. Study quality was assessed by two independent reviewers using a modified version of the Newcastle-Ottawa Quality Assessment Scale. Ventriculomegaly was defined as either mild or severe when ventricular diameter measured as 10-15 or >15 mm, respectively. Meta-analyses were conducted for adverse neurodevelopmental outcome, intrauterine fetal demise and infant mortality. Following the removal of duplicates, the search yielded 2,452 citations, of which 23 studies were included and 8 were eligible for meta-analysis. There were 767 and 347 cases of mild and severe isolated fetal ventriculomegaly, respectively. Adverse outcomes were consistently reported at a higher rate in severe cases than mild. The relative risks of adverse neurodevelopmental outcome, intrauterine fetal demise and infant mortality were 4.24 [95% confidence interval (CI): 2.46-7.30], 4.46 (95% CI: 1.64-12.11) and 6.02 (95% CI: 1.73-21.00), respectively, upon comparison of mild versus severe cases of isolated fetal ventriculomegaly. The likelihood of adverse neurodevelopmental and perinatal outcomes, including intrauterine and infant mortality, is increased in severe isolated fetal ventriculomegaly compared to mild isolated fetal ventriculomegaly.

Assessment of Macular Thickness in Different Grades of Myopia: An Optical Coherence Tomography Study in a Rural Tertiary Care Hospital

Abstract Background: Myopia is a condition related to the refractive error that causes visual disability. Due to its high prevalence, it can contribute to complicated cataracts and related conditions such as primary open-angle glaucoma. The risks of retinal detachment, chorioretinal atrophy, pigmentary degeneration, vitreous degeneration and retinal breaks may increase with an increase in axial length and severity of myopia, among other long-term effects of high myopia. The aim of this study was to assess the role of macular thickness and myopia in non-invasive optical coherence tomography (OCT). Materials and Methods: This was a prospective, hospital-based observational study conducted for 18 months in a tertiary care centre in Karnataka. A total of 155 consecutive myopia patients aged ≥10 years attending the outpatient Department of Ophthalmology were included in the study. The data were analysed using the Statistical Package for Social Sciences (SPSS) for Windows, version 22.0 (SPSS Inc., Chicago). Result: The participants aged from 10 to 75 years with a female preponderance of 60%. The mean age of participants is 31.95 yrs. The majority of the patients had mild myopia (91.6%), compared with moderate (5.8%) and high (2.6%) myopia. The mean value of best-corrected visual acuity improved from 0.67 to 0.08 in high, 0.94 to 0.22 in mild and 0.71 to 0.26 in moderate myopia patients. The mean maximum retinal thickness was 472 micrometres, and the mean minimum retinal thickness was 178 micrometres. Conclusion: There is a high prevalence of mild myopia cases, especially at extremes of age. Myopia was more common among females. There was a significant difference among different classes of myopia with respect to uncorrected and best-corrected visual acuity. The parafovea was thinner and the fovea thicker among myopia.

Relapse Correction with Removable Orthodontic

Relapse is when the teeth return to the position before orthodontic treatment. The small gaps between teeth often occur due to relapse conditions. A removable appliance is an orthodontic appliance that the patient can remove and insert themselves. This aims to report a relapse case treated using removable orthodontics. The case, A 26-year-old female patient complained of upper front teeth being gapped and lower front teeth being crowded. Previous dental history showed that the teeth had been treated with a fixed orthodontic appliance one year ago with premolar extraction. The patient did not use a retainer. The removable orthodontic appliance used was an active plate that retracted the maxillary anterior teeth using a labial bow. Orthodontic relapse can occur due to incomplete remodelling. Retraction using a labial bow can close the anterior teeth palatally. Active plates can be used as an alternative treatment in mild cases of relapse after fixed orthodontic treatment

The Importance of Evaluating Sudomotor Function in the Diagnosis of Cardiac Autonomic Neuropathy.

Cardiac autonomic neuropathy (CAN) is a disorder affecting the autonomic nerves that regulate the cardiovascular system, leading to irregular heart rate and blood pressure control. It is commonly associated with diabetes mellitus but can also result from other conditions such as autoimmune disorders, chronic kidney disease, alcohol abuse, and certain medications. Screening for CAN is essential, particularly in individuals with poor glycemic control, cardiovascular risk factors, or complications. Early identification of CAN is vital for timely intervention to prevent or manage cardiovascular complications effectively. Regular screening helps detect CAN before symptoms emerge, enabling early intervention to slow or halt its progression. This study examined the relationship between sudomotor function and cardiovascular reflex tests. This was a cross-sectional study conducted between June 2019 and June 2020. The study included 271 subjects aged 18 years and above who provided informed consent, were diagnosed with type 2 diabetes mellitus (T2DM), and were overweight or obese. Exclusion criteria encompassed patients with other types of diabetes, pregnant women, those with recent neoplasm diagnoses, stroke sequelae, history of myocardial infarction, or pelvic limb amputations. The assessment of cardiac autonomic neuropathy involved conducting an electrocardiogram and evaluating the QTc interval in the morning before taking medication. Additionally, cardiovascular reflex tests (CART) were conducted, including assessments of heart rate variability during deep breathing, the Valsalva maneuver, and changes in orthostatic position. Simultaneously, the diagnosis of CAN was assessed by performing a sweat test using a Sudoscan assessment (Impeto Medical, Moulineaux, France). Results: More than half of the participants (52%, n=143) were female. Significant differences in statistical measures were noted between females and males regarding age, systolic blood pressure, fasting blood glucose, A1c level, total cholesterol, triglycerides, gamma-glutamyl transferase, and bilirubin levels. Within the CAN-diagnosed group (CAN+), 40.92% were classified as mild cases (n=90), 47.27% as moderate cases (n=104), and 11.81% as severe cases (n=26). Among the CAN+ group, 54% (n=119) were women. Electrochemical skin conductance was lower in the CAN+ group than the CAN- group in hands (67.34±15.51 μS versus 72.38±12.12 μS, p=0.008) and feet (73.37±13.38 μS versus 82.84 ±10.29 μS, p<0.001). The Sudoscan-CAN score significantly correlated with Ewing scores (r= 0.522, p<0.001). In multiple linear regression analysis, the Sudoscan-CAN score remained significantly associated with age, high BMI, long-standing diabetes, and Ewing score. Sudoscan demonstrates potential in identifying patients with an increased risk of CAN. Its integration into clinical practice can improve patient outcomes through early detection, risk stratification, and personalized treatment approaches. Its non-invasive, portable, and user-friendly features render it suitable for utilization in outreach programs or resource-constrained settings as part of screening efforts designed to pinpoint high-risk individuals for additional assessment.

Serum VEGF-A levels on admission in COVID-19 patients correlate with SP-D and neutrophils, reflecting disease severity: A prospective study

Background and objectiveThe coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in significant global morbidity and mortality. This study aimed to investigate the clinical significance of serum vascular endothelial growth factor A (VEGF-A) in COVID-19 patients and its association with disease severity and pulmonary injury. MethodsWe prospectively collected data from 71 hospitalized COVID-19 patients between June 2020 and January 2021. Patients were classified as either mild or severe based on their oxygen requirements during hospitalization. Serum VEGF-A levels were measured using an ELISA kit. ResultsIn comparison to mild cases, significantly elevated serum VEGF-A levels were observed in severe COVID-19 patients. Furthermore, VEGF-A levels exhibited a positive correlation with white blood cell count, neutrophil count, and lymphocyte count. Notably, serum surfactant protein-D (SP-D), an indicator of alveolar epithelial cell damage, was significantly higher in patients with elevated VEGF-A levels. ConclusionThese results suggest that elevated serum VEGF-A levels could serve as a prognostic biomarker for COVID-19 as it is indicative of alveolar epithelial cell injury caused by SARS-CoV-2 infection. Additionally, we observed a correlation between VEGF-A and neutrophil activation, which plays a role in the immune response during endothelial cell injury, indicating a potential involvement of angiogenesis in disease progression. Further research is needed to elucidate the underlying mechanisms of VEGF-A elevation in COVID-19.

Impact of FilmArray respiratory panel test for hospitalized pediatric respiratory tract infection in Taiwan: A 3-year single-center cohort study.

Respiratory tract infections are prevalent and clinically significant in pediatric populations globally. However, pathogen testing often involves time-consuming processes, resulting in delays in diagnosis. To date, commercial testing machines, such as the FilmArray respiratory panel, have been proposed for hospitals. Therefore, this study aimed to investigate the impact of the FilmArray respiratory panel at a single center. This study utilized the medical records of our hospital to select pediatric inpatients with respiratory tract infections who underwent the FilmArray respiratory panel between September 2020 and April 2021 and those who did not undergo nucleic acid detection (a rapid test group) between September 2019 and April 2020. FilmArray is a polymerase chain reaction-based diagnostic tool. The FilmArray respiratory panel group was scheduled to recruit 150 patients (final 137 patients), whereas the rapid test group was scheduled to recruit 300 patients (final 267 patients). Differences in continuous variables between the 2 groups were analyzed using independent Student t tests. The FilmArray respiratory panel group had a longer length of inpatient days, longer duration of antibiotic use, and higher proportion of pathogens that tested positive, with significant differences than those in the rapid test group. Fever duration showed no significant difference between the 2 groups. For the polymerase chain reaction method, respiratory syncytial virus was the most commonly detected pathogen causing pneumonia, followed by human rhinovirus/enterovirus and parainfluenza virus. Mycoplasma was detected using the rapid test but not with the FilmArray respiratory panel. The FilmArray respiratory panel provides clinicians with a rapid and useful diagnostic tool. The effect was quite good for virus detection, but not for bacteria. Given its limited adoption, the tool may not aid clinicians in the diagnosis of mild cases.

Long term follow-up of axial length and orbital dimensions in congenital microphthalmia and anophthalmia.

To evaluate axial length (AL), orbital width (OW) and height (OH) development in congenital microphthalmia and anophthalmia (MICA) using serial ultrasonography measurements. A longitudinal prospective cohort (n = 74) of unilaterally and bilaterally affected MICA patients was followed from 2013 to 2022 at the university hospital in Amsterdam, the Netherlands. Clinical entity, age, severity category based on axial length, conformer treatment and intra-orbital cysts were registered. The main outcome measures were the absolute and relative growth of AL, OW and OH. Surgical and intra-orbital cyst cases were described separately. Absolute microphthalmic eye size increased in 27/49 (55%) unilateral MICA eyes, but growth arrest/decrease in the remaining could shift the case to a more severe category over time. A final affected/unaffected orbital symmetry ≥80% was seen in the large majority of unilateral cases (45/46 for OW, 43/46 for OH). Cases with AL < 10.5 mm had orbital symmetry <80% more often. Most orbital symmetry changes were seen in moderate and severe unilateral cases treated with 3D-printed conformer therapy starting at age <1 year, with 6/10 (60%) symmetry increase, 30% unchanged symmetry and 10% symmetry decrease. All cases older than 6.5 years (n = 6) did not show any change anymore, regardless of treatment. For bilateral and unilateral mild cases, orbital dimensions kept the same proportions during follow-up, with or without conformer treatment. Using severity categories in MICA based on relative AL may aid the decision to start conformer treatment, as most orbital symmetry changes were seen in moderate and severe unilateral cases receiving 3D-printed conformer therapy that started under age 1.
