Opto-electronic and thermophysical characteristics of A2TlAgF6 (A = Rb, Cs) for green technology applications.

Lead-free double perovskites are unique materials for transport and optoelectronic applications that use clean resources to generate energy. Using first-principle computations, this study thoroughly investigates the structural, thermoelectric, and optical attributes of A2TlAgF6 (A = Rb, Cs). Tolerance factor and formation energy estimates are used to verify that these materials exist in the cubic phase. Elastic constants with high melting temperature values are ductile when evaluated for mechanical stability using the Born stability criterion. The optical absorption band is adjusted from 2 to 4 eV via band gaps of 1.88 and 1.99 eV, as indicated by band structures. Analysis of optical properties reveals perfect absorption in the visible spectrum, whole polarization, and low optical loss. Furthermore, thermoelectric properties are assessed at 300, 500, and 700 K in the range of -0.5 to 3 eV for chemical potential (µ). The materials exhibit significant improvements in the Figure of Merit scale due to their elevated electrical conductivity, Seebeck coefficient, and extremely low thermal conductivity values.

The metabolic fingerprint of chronic hepatitis C progression: Metabolome shifts and cutting-edge diagnostic options.

Hepatitis C virus infection causes chronic diseases such as cirrhosis and hepatocellular carcinoma. Metabolomics research has been shown to be linked to pathophysiologic pathways in liver illnesses. The aim of this study was to investigate the serum metabolic profile of patients with chronic hepatitis C (CHC) infection and to identify underlying mechanisms as well as potential biomarkers associated with the disease. Nuclear magnetic resonance (NMR) was used to evaluate the sera of 83 patients with CHC virus and 52 healthy control volunteers (NMR). Then, multivariate statistical analysis was used to find distinguishing metabolites between the two groups. Sixteen out of 40 metabolites including include 3-HB, betaine, carnitine, creatinine, fucose, glutamine, glycerol, isopropanol, lysine, mannose, methanol, methionine, ornithine, proline, serine, and valine-were shown to be significantly different between the CHC and normal control (NC) groups (variable importance in projection >1 and p < 0.05). All the metabolic perturbations in this disease are associated with pathways of Glycine, serine, and threonine metabolism, glycerolipid metabolism, arginine and proline metabolism, aminoacyl-tRNA biosynthesis, cysteine and methionine metabolism, alanine, aspartate, and glutamate metabolism. Multivariate statistical analysis constructed using these expressed metabolites showed CHC patients can be discriminated from NCs with high sensitivity (90%) and specificity (99%). The metabolomics approach may expand the diagnostic armamentarium for patients with CHC while contributing to a comprehensive understanding of disease mechanisms.

Differences in corneal nerve fiber density and fiber length in patients with painful chronic idiopathic axonal polyneuropathy and diabetic polyneuropathy.

INTRODUCTION/AIMS: Corneal confocal microscopy (CCM) detects small nerve fiber loss and correlates with skin biopsy findings in diabetic neuropathy. In chronic idiopathic axonal polyneuropathy (CIAP) this correlation is unknown. Therefore, we compared CCM and skin biopsy in patients with CIAP to healthy controls, patients with painful diabetic neuropathy (PDN) and diabetics without overt neuropathy (DM). METHODS: Participants with CIAP and suspected small fiber neuropathy (n = 15), PDN (n = 16), DM (n = 15), and healthy controls (n = 16) underwent skin biopsy and CCM testing. Inter-center intraclass correlation coefficients (ICC) were calculated for CCM parameters. RESULTS: Compared with healthy controls, patients with CIAP and PDN had significantly fewer nerve fibers in the skin (IENFD: 5.7 ± 2.3, 3.0 ± 1.8, 3.9 ± 1.5 fibers/mm, all p < .05). Corneal nerve parameters in CIAP (fiber density 23.8 ± 4.9 no./mm2, branch density 16.0 ± 8.8 no./mm2, fiber length 13.1 ± 2.6 mm/mm2) were not different from healthy controls (24.0 ± 6.8 no./mm2, 22.1 ± 9.7 no./mm2, 13.5 ± 3.5 mm/mm2, all p > .05). In patients with PDN, corneal nerve fiber density (17.8 ± 5.7 no./mm2) and fiber length (10.5 ± 2.7 mm/mm2) were reduced compared with healthy controls (p < .05). CCM results did not correlate with IENFD in CIAP patients. Inter-center ICC was 0.77 for fiber density and 0.87 for fiber length. DISCUSSION: In contrast to patients with PDN, corneal nerve parameters were not decreased in patients with CIAP and small nerve fiber damage. Therefore, CCM is not a good biomarker for small nerve fiber loss in CIAP patients.

Comparison between umbilical and right upper transverse abdominal incisions for pyloromyotomy: a systematic review and meta-analysis.

The aim of this study was to compare the operative parameters and complication rates between the umbilical (UMB) and right upper quadrant (RUQ) skin incisions for Ramstedt's pyloromyotomy for the treatment of infantile hypertrophic pyloric stenosis (IHPS). PubMed, EMBASE, Web of Science and Scopus databases were systematically searched. The studies where any one of the main outcomes of interest, i.e., operative time, wound infection rate, mucosal perforation rate were reported were eligible for inclusion. The statistical analysis was performed using a random-effects model. The methodological quality of the studies was assessed utilizing the Newcastle-Ottawa Scale. Fifteen studies comprising 2964 infants were included. As compared to the UMB group, the RUQ group showed a significantly lower mean operative time (p = 0.0004), wound infection rate (p < 0.0001) and mucosal perforation rate (p = 0.02). Although UMB incision produces an almost undetectable scar, this approach results in significantly more complications. Therefore, the risks and benefits must be weighed and discussed with the caregivers in deciding the surgical approach in patients with IHPS. However, due to a poor methodological quality of nine out of fifteen studies, further studies need to be conducted for an optimal comparison between the two groups.

Utility of thiol/disulphide homeostasis as a biomarker for acute appendicitis: a systematic review and meta-analysis.

The aim of this study was to analyze the role of thiol/disulfide homeostasis (TDH) parameters as an indicator of oxidative stress in acute appendicitis (AA). PubMed, EMBASE, Web of Science, and Scopus databases were systematically searched. Studies reporting on TDH in AA (both complicated and uncomplicated cases) were included. The comparator group were healthy controls. The TDH domain was compared between the groups using anti-oxidant parameters, namely native thiol and total thiol levels, and native thiol/total thiol ratio; and oxidant parameters, namely disulfide level, disulfide/native thiol ratio, and disulfide/total thiol ratio. The statistical analysis was performed using a random-effects model. The methodological quality of the studies was assessed utilizing the Newcastle-Ottawa scale. Eleven studies with a total of 926 subjects, comprising 457 patients with uncomplicated appendicitis, 147 with complicated appendicitis, and 322 healthy controls were included. Our study demonstrated significantly increased oxidative stress in AA as compared to healthy controls in all TDH parameters and significantly lower total thiol levels in complicated AA as compared to uncomplicated AA. Due to a poor methodological quality in five out of eleven studies, future prospective studies with adequate power are essential to validate these observations and refine the diagnostic approaches to AA.

Clearance of interstitial fluid (ISF) and CSF (CLIC) group-part of Vascular Professional Interest Area (PIA), updates in 2022-2023. Cerebrovascular disease and the failure of elimination of Amyloid-ß from the brain and retina with age and Alzheimer's disease: Opportunities for therapy.

This editorial summarizes advances from the Clearance of Interstitial Fluid and Cerebrospinal Fluid (CLIC) group, within the Vascular Professional Interest Area (PIA) of the Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment (ISTAART). The overarching objectives of the CLIC group are to: (1) understand the age-related physiology changes that underlie impaired clearance of interstitial fluid (ISF) and cerebrospinal fluid (CSF) (CLIC); (2) understand the cellular and molecular mechanisms underlying intramural periarterial drainage (IPAD) in the brain; (3) establish novel diagnostic tests for Alzheimer's disease (AD), cerebral amyloid angiopathy (CAA), retinal amyloid vasculopathy, amyloid-related imaging abnormalities (ARIA) of spontaneous and iatrogenic CAA-related inflammation (CAA-ri), and vasomotion; and (4) establish novel therapies that facilitate IPAD to eliminate amyloid ß (Aß) from the aging brain and retina, to prevent or reduce AD and CAA pathology and ARIA side events associated with AD immunotherapy.

Classification of bruxism based on time-frequency and nonlinear features of single channel EEG.

BACKGROUND: In the classification of bruxism patients based on electroencephalogram (EEG), feature extraction is essential. The method of using multi-channel EEG fusing electrocardiogram (ECG) and Electromyography (EMG) signal features has been proved to have good performance in bruxism classification, but the classification performance based on single channel EEG signal is still understudied. We investigate the efficacy of single EEG channel in bruxism classification. METHODS: We have extracted time-domain, frequency-domain, and nonlinear features from single EEG channel to classify bruxism. Five common bipolar EEG recordings from 2 bruxism patients and 4 healthy controls during REM sleep were analyzed. The time domain (mean, standard deviation, root mean squared value), frequency domain (absolute, relative and ratios power spectral density (PSD)), and non-linear features (sample entropy) of different EEG frequency bands were analyzed from five EEG channels of each participant. Fine tree algorithm was trained and tested for classifying sleep bruxism with healthy controls using five-fold cross-validation. RESULTS: Our results demonstrate that the C4P4 EEG channel was most effective for classification of sleep bruxism that yielded 95.59% sensitivity, 98.44% specificity, 97.84% accuracy, and 94.20% positive predictive value (PPV). CONCLUSIONS: Our results illustrate the feasibility of sleep bruxism classification using single EEG channel and provides an experimental foundation for the development of a future portable automatic sleep bruxism detection system.

Study of Intrahepatic Biliary Architecture in Patients Operated for Extrahepatic Biliary Atresia using Magnetic Resonance Cholangiopancreatography.

Aim: The aim is to study intrahepatic biliary architecture in patients following Kasai's portoenterostomy for extrahepatic biliary atresia using magnetic resonance cholangiopancreatography (MRCP). Materials and Methods: It is a prospective observational study in a cohort of patients who have survived with a complete jaundice-free period for at least 1 year. MRCP was done to look for various intrahepatic architectural changes during their last visit. Findings were correlated with liver functions and growth and development. Results: Twenty-one patients were included in the study. The male-to-female sex ratio was 1.6:1, the median age at surgery was 75 days (18-140 days), and the median age at magnetic resonance imaging (MRI) was 4 years (18 months-18 years). More than 2 years of follow-up was in seven patients. Left lobe hypertrophy was observed in six patients, right lobe hypertrophy was in three patients, intrahepatic biliary tract dilatation was in five patients, and altered signal intensity between intrahepatic ducts was seen in five patients. In addition, hypointense foci in the spleen were seen in one patient. Twelve children had normal weight for their age, ten children had the normal height for their age, and gamma-glutamyl transferase was elevated in all children. Only four children had a history of fever and jaundice. Conclusions: The patients who survive after successful surgical intervention have near-normal liver gross architecture as on MRI/MRCP. Occasional findings of dilatation and lobar atrophy/hypertrophy are possible, especially in those with a history of cholangitis. The survivors also have acceptable growth parameters and normal liver functions.

Recognition and order of multiple sidechains by metal-organic framework enhances the separation of hexane isomers.

Porous materials perform molecular sorting, separation and transformation by interaction between their framework structures and the substrates. Proteins also interact with molecules to effect chemical transformations, but rely on the precise sequence of the amino acid building units along a common polypeptide backbone to maximise their performance. Design strategies that positionally order sidechains over a defined porous framework to diversify the internal surface chemistry would enhance control of substrate processing. Here we show that different sidechains can be ordered over a metal-organic framework through recognition of their distinct chemistries during synthesis. The sidechains are recognised because each one forces the common building unit that defines the backbone of the framework into a different conformation in order to form the extended structure. The resulting sidechain ordering affords hexane isomer separation performance superior to that of the same framework decorated only with sidechains of a single kind. The separated molecules adopt distinct arrangements within the resulting modified pore geometry, reflecting their strongly differentiated environments precisely created by the ordered sidechains. The development of frameworks that recognize and order multiple sidechain functionality by conformational control offers tailoring of the internal surfaces within families of porous materials to direct interactions at the molecular level.

Parkinsonian daytime sleep-wake classification using deep brain stimulation lead recordings.

Excessive daytime sleepiness is a recognized non-motor symptom that adversely impacts the quality of life of people with Parkinson's disease (PD), yet effective treatment options remain limited. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an effective treatment for PD motor signs. Reliable daytime sleep-wake classification using local field potentials (LFPs) recorded from DBS leads implanted in STN can inform the development of closed-loop DBS approaches for prompt detection and disruption of sleep-related neural oscillations. We performed STN DBS lead recordings in three nonhuman primates rendered parkinsonian by administrating neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Reference sleep-wake states were determined on a second-by-second basis by video monitoring of eyes (eyes-open, wake and eyes-closed, sleep). The spectral power in delta (1-4 Hz), theta (4-8 Hz), low-beta (8-20 Hz), high-beta (20-35 Hz), gamma (35-90 Hz), and high-frequency (200-400 Hz) bands were extracted from each wake and sleep epochs for training (70% data) and testing (30% data) a support vector machines classifier for each subject independently. The spectral features yielded reasonable daytime sleep-wake classification (sensitivity: 90.68 ± 1.28; specificity: 88.16 ± 1.08; accuracy: 89.42 ± 0.68; positive predictive value; 88.70 ± 0.89, n = 3). Our findings support the plausibility of monitoring daytime sleep-wake states using DBS lead recordings. These results could have future clinical implications in informing the development of closed-loop DBS approaches for automatic detection and disruption of sleep-related neural oscillations in people with PD to promote wakefulness.

Study of mechanical, optical, and thermoelectric characteristics of Ba2 XMoO6 (X = Zn, Cd) double perovskite for energy harvesting.

The double perovskites are become the emerging aspirant to fulfill the demand of energy. Therefore, the optoelectronic, elastic and transport characteristics of Ba2 XMoO6 (X = Zn, Cd) are addressed systemically. The elastic constants show the mechanical stability. The nature of Ba2 ZnMoO6 is brittle and Ba2 CdMoO6 is ductile with large values of Debye temperature covalent bonding. The electronic band structures exhibit band gaps of 2.81 and 2.98 eV, which increase their importance for optoelectronic applications. The absorption of light energy, optical loss, refractive index, polarization of light energy are addressed in the energy range zero to 14 eV. Furthermore, thermoelectric characteristics are computed against chemical potentials at 300, 600, and 900 K. The chemical potential decides the p-type nature, with holes as majority carriers. The increasing temperature increases the power factor and figure of merit. Therefore, the optoelectronic and thermoelectric characteristics reveals the importance of studied DPs for energy applications.

Molecular Docking Studies of Phyllanthus niruri Root Phytoconstituents for Antibreast Cancer Activity Using Multiple Proteins.

The systematic exploitation of the structural variety of natural products is made possible by docking studies, which have been shown to be a crucial technique. The objective of the current work was to use molecular docking studies with different proteins to identify acceptable and efficient compounds from root phytoconstituents of Phyllanthus niruri plant. Numerous human disorders have been treated using Phyllanthus niruri. Antioxidant, antibacterial, antifungal, anti-inflammatory, antipyretic, antimalarial, antiviral, immunomodulatory, antidepressant, anticonvulsant, antinociceptive, anti-ulcer, anti-arthritic, anticancer, hyperlipidemia, and antifertility were only a few of its many pharmacological effects. One of the most prevalent malignancies in women worldwide, breast cancer is one of the leading causes of mortality worldwide. The most successful breast cancer treatments now on the market have negative side effects and are useless in people. In order to develop drugs, molecules with such a framework have been utilized as the lead. Schrodinger Maestro (v13.0) software was used to conduct a molecular docking analysis of root components with certain proteins linked to the illnesses. In comparison to commercially available conventional medications, molecular docking data also demonstrated greater scores. Dacarbazine's ability to treat cancer was utilized as benchmark to assess the in silico outcomes and grading of virtual screening or molecular docking.

A Historical Perspective on Chronic Obstructive Pulmonary Disease: From Past to Present.

René-Théophile-Hyacinthe Laennec in his book "Treatise of the Diseases of the Chest" discussed the emphysema in 1821. Chronic obstructive pulmonary disease (COPD) has been around for at least 202 years, from 1821 to 2023 (but the disease itself is much older than that). It is believed that William Briscoe first used the term COPD in June 1965, at the 9th Aspen Emphysema Conference. COPD was first defined by the CIBA guest symposium in 1959 and the American Thoracic Society Committee on Diagnostic Standards in 1962; recent definition of COPD was released by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) report 2023. In 1990, it was sixth leading cause of death and in 2020 COPD becomes third leading cause of death. GOLD update 2023 also proposed taxonomy (etiotypes), classification of COPD based on risk factors, and ABE assessment tool for COPD. Now concept of early-COPD, pre-COPD, and, mild-COPD are also emerging, which are helpful in better understanding of COPD. Here, we have discussed historical landmarks, definition, burden, taxonomy, classification, different concept of disease, ABE assessment tool, personalized medicine, and brief description of GOLD and World COPD Day from past to present.

Nanoencapsulation of Docetaxel Induces Concurrent Apoptosis and Necroptosis in Human Oral Cancer Cells (SCC-9) via TNF-α/RIP1/RIP3 Pathway.

Human oral squamous cell carcinoma is the sixth most frequent malignant cancer, with an unacceptably high death rate that affects people's health. Albeit, there are several clinical approaches for diagnosing and treating oral cancer they are still far from ideal. We previously synthesised and characterised the docetaxel nanoformulation (PLGA-Dtx) and discovered that docetaxel nanoencapsulation may suppress oral cancer cells. The goal of this study was to figure out the mechanism involved in the suppression of oral cancer cell proliferation. We discovered that PLGA-Dtx inhibited SCC-9 cell growth considerably as compared to free docetaxel (Dtx), and that the viability of SCC-9 cells treated with PLGA-Dtx was decreased dose-dependently. MTT assay showed that PLGA-Dtx selectively inhibited the growth of PBMCs from oral cancer patients while sparing PBMCs from normal healthy controls. Further, flow cytometry analysis showed that PLGA-Dtx induced apoptosis and necroptosis in SCC-9 cells. G2/M cell cycle arrest has been confirmed on exposure of PLGA-Dtx for 24 h in SCC-9 cells. Interestingly, western blot investigation found that PLGA-Dtx increased the amounts of necroptic proteins and apoptosis-related proteins more efficiently than Dtx. Furthermore, PLGA-Dtx was more effective in terms of ROS generation, and mitochondrial membrane potential depletion. Pretreatment with necroptosis inhibitor Nec-1 efficiently reversed the ROS production and further recover MMP caused by PLGA-Dtx. Overall, this study revealed a mechanistic model of therapeutic response for PLGA-Dtx in SCC-9 cells and proposed its potency by inducing cell death via activation of concurrent apoptosis and necroptosis in SCC-9 cells via TNF-α/RIP1/RIP3 and caspase-dependent pathway.

Bibliometric Analysis and Visualization of the Extrahepatic Portal Venous Obstruction Publication Landscape.

Introduction: A scientometric analysis was conducted to characterize the global research publications in extrahepatic portal venous obstruction (EHPVO), and state-of-the-art visualization graphics were generated to provide insight into specific bibliometric variables. Materials and Methods: The Web of Science database was accessed for research productivity and bibliometric variables of countries, institutions, authors, journals, and content analysis of top-20 cited documents were performed. Collaborative networks and co-occurrence of keywords map were generated using VOSviewer software. Results: Two hundred and sixteen records were retrieved with an annual growth rate of 2.53%. India is the leading country in productivity (n = 4339), followed by the USA and China. Post Graduate Institute of Medical Education and Research, Chandigarh, was the top productive institute. Sarin SK was the most prolific author, having the highest citations received and h-index. The hotspot topics were "portal hypertension," "cirrhosis," "children," "biliopathy/cholangiopathy," "liver fibrosis," and "liver transplantation" as per keyword co-occurrence networking. J Gastroenterol Hepatol had the most publications of EHPVO research as well the h-index. Regarding collaborative network mapping, the USA and Primignani M were the significant nodes among country and author, respectively. Conclusion: EHPVO research publication volume is low but is gradually progressing with dominant contributions from Indian institutes and authors. Most highly cited articles are of low level of evidence, and multi-institutional collaborative research can be the way forward.

Defining the Indications of PATIO Technique for Urethrocutaneous Fistula Repair.

Introduction: Despite the advancements in technique and technology, urethrocutaneous fistula (UCF) formation continues to be the most common complication after hypospadias repair. Objective: The objective of the current synthesis is to define the indications of PATIO technique for UCF repair. Materials and Methods: The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Scopus, Ovid, Embase, Web of Science, and Google Scholar were interrogated for studies presenting primary data upon UCF repair by the PATIO technique. Data analysis was performed on MedCalc and R software. Results: Eighteen studies were identified relevant to the current context: inversion of UCF tract has been described in 13 and ligation in 5. There were 2 duplications (abstract and manuscript). The overall success for PATIO is 88.2% (314/356). The success rate was variable between classic PATIO (inversion at 87.2%), ligation-inversion at 86.9%, and ligation alone at 88.9%. The success rate was not improvised upon by supplementing inversion of UCF tract with ligation (p = 0.957) or addition of a waterproofing layer (p = 0.622). PATIO has been used for single or multiple UCFs post hypospadias repair, genital piercing, and genitoplasty in cis- or transgender population for UCF up to 5 mm in size. The success rates were best for UCF <2 mm and worst for those approaching 5 mm. The results were, however, unaffected by the location of UCF along the penile shaft. Besides, the use of urethral catheter is optional and may be eliminated with shorter hospitalization. Conclusions: PATIO repair may be considered for repair of UCFs (a) with diverse etiologies, (b) located anywhere along the penile shaft included coronal UCF, (c) preferably <4 mm in size, (d) single or multiple in number; multiple PATIOs may be done in the same setting, (e) in patients unwilling for prolonged hospitalization, (f) in patients unwilling for a urethral catheter, and (g) in hypospadias cripples wherein mobilization of distant tissues such as tunica vaginalis flap or a buccal mucosal graft may be required for supplementing the UCF repair.

Role of Procalcitonin as a Biomarker in Early Identification of Adverse Events Following Esophageal Atresia Surgery.

Introduction: Surgical complication following esophageal atresia repair is one of the several factors known to influence the final outcomes. Early identification of such complications may help in timely institution of therapeutic measures and translate into improved prognosis. Objective: The objective of this study was to evaluate the role of procalcitonin in early prediction of the adverse events after surgery in patients of esophageal atresia and the temporal relationship with clinical manifestations and other inflammatory biomarkers such as C-reactive protein (CRP). Materials and Methods: This was a prospective study on consecutive patients of esophageal atresia (n = 23). Serum procalcitonin and CRP levels were assessed at baseline (prior to surgery) and on postoperative days (POD) 1, 3, 5, 7, and 14. The trends in the biomarker values and temporal relationships of deviation in trend with the clinical and conventional laboratory parameters and patient outcomes were analyzed. Results: Baseline serum procalcitonin was elevated (n = 23; 1.7 ng/ml: min: 0.07 ng/ml-max: 24.36 ng/ml) in 18/23 (78.3%) patients. Procalcitonin nearly doubled on POD-1 (n = 22; 3.28 ng/ml: min: 0.64 ng/ml-max: 16.51 ng/ml) followed by a gradual decline. CRP was also elevated on POD-1 (three times the baseline) and depicted a delayed peak at POD-3. POD-1 procalcitonin and CRP levels correlated with survival. POD-1 procalcitonin cutoff at 3.28 ng/ml predicted mortality with a sensitivity and specificity of 100% and 57.9% (P = 0.05). Serum procalcitonin and CRP were higher for patients who sustained complications, so was the time required for hemodynamic stabilization. Procalcitonin (baseline and POD-5) and CRP (POD-3 and POD-5) values correlated with the clinical course after surgery. Baseline procalcitonin cutoff at 2.91 ng/ml predicted the possibility of a major complication with a sensitivity of 71.4% and a specificity of 93.3%. POD-5 procalcitonin cutoff at 1.38 ng/ml predicted the possibility of a major complication with a sensitivity of 83.3% and a specificity of 93.3%. Patients who sustained major complications depicted a change in serum procalcitonin trend 24-48 h ahead of clinical manifestation of an adverse event. Conclusions: Procalcitonin is a good indicator to identify the adverse events in neonates after surgery for esophageal atresia. The procalcitonin levels in patients who sustained a major complication depicted a reversal in trend 24-48 h of clinical manifestation. POD-1 procalcitonin correlated with survival while the baseline and POD-5 serum procalcitonin predicted the clinical course.

Immunisation with UB-312 in the Thy1SNCA mouse prevents motor performance deficits and oligomeric α-synuclein accumulation in the brain and gut.

Alpha synuclein has a key role in the pathogenesis of Parkinson's disease (PD), Dementia with Lewy Bodies (LBD) and Multiple System Atrophy (MSA). Immunotherapies aiming at neutralising toxic αSyn species are being investigated in the clinic as potential disease modifying therapies for PD and other synucleinopathies. In this study, the effects of active immunisation against αSyn with the UB-312 vaccine were investigated in the Thy1SNCA/15 mouse model of PD. Young transgenic and wild-type mice received an immunisation regimen over a period of 6 weeks, then observed for an additional 9 weeks. Behavioural assessment was conducted before immunisation and at 15 weeks after the first dose. UB-312 immunisation prevented the development of motor impairment in the wire test and challenging beam test, which was associated with reduced levels of αSyn oligomers in the cerebral cortex, hippocampus and striatum of Thy1SNCA/15 mice. UB-312 immunotherapy resulted in a significant reduction of theαSyn load in the colon, accompanied by a reduction in enteric glial cell reactivity in the colonic ganglia. Our results demonstrate that immunisation with UB-312 prevents functional deficits and both central and peripheral pathology in Thy1SNCA/15 mice.

Association of basic vaccination with cognitive and learning ability among children: insights from the India Human Development Survey, 2004-05 and 2011-12.

Basic vaccination is important to protect children from infectious diseases and illnesses. Adequate levels of vaccination coverage reduce the morbidity and mortality burden among children and promote their physical and mental development. This study aimed to assess the association between basic childhood vaccination and the cognitive and learning ability of school children in India. Nationally representative follow-up data on 6183 children from the Indian Human Development Surveys conducted in 2004-05 and 2011-12 (IHDS I & II) were analysed. Children aged 8-10 years who had received all basic vaccines by the age 12 months performed better in a maths test than partially vaccinated or unvaccinated children (OR: 1.87, 95% CI: 1.48, 2.35). Similarly, fully vaccinated children performed better in writing tasks than partially vaccinated or unvaccinated children (OR: 1.77, 95% CI: 1.44, 2.18). Likewise, fully vaccinated children had better reading skills than fully unvaccinated children (OR: 1.60, 95% CI: 1.23, 2.09). The results suggest that enhancing child vaccination coverage can have significant benefits beyond health and can potentially improve the long-term educational outcomes of children.

A cross-sectional study to determine the psychological distress among pulmonary tuberculosis patients during COVID-19 pandemic.

COVID-19 pandemic had adversely affected the services of the National Tuberculosis (TB) Elimination Programme, resulting in psychological distress among pulmonary tuberculosis patients (PTB). This cross-sectional, hospital-based study included 361 PTB patients. Three pre-defined questionnaires were used for the analysis, a questionnaire to evaluate anxiety related to COVID-19, a patient health questionnaire (PHQ-9) for depression, and a fear of COVID-19 scale (FCV-19S) questionnaire. Among 361 PTB patients, 13% (n=47) had COVID-19 infection. Out of the total patients, 69% (n=250) were DR-TB (drug resistance-tuberculosis) cases. Proportion of anxiety, fear and depression due to COVID-19 was found in 49% (n=177), 23% (n=83), 67% (n=247) respectively. Delay in the initiation of anti-tubercular treatment was found in 58% (n=210) of the cases, among which the majority, i.e., 69% (n=172, p=0.011), were DR-TB. This pandemic has led to a sudden step-down of PTB. Trend analysis of the psychological distress showed a peak following the COVID-19 pandemic. Most DR-TB patients had delayed initiation of the anti-tubercular treatment during the pandemic. The preponderance of the younger age group was seen in the pulmonary tuberculosis patients, and a majority of them had DR-TB. Depression was the predominant psychological distress among the study subjects during the pandemic.
