Abstract
AIM AND OBJECTIVE The study aimed to explore the correlation between dermatoglyphic patterns and quantitative palatal anatomic variables in individuals with different growth patterns. MATERIALS AND METHOD A cross-sectional study was conducted involving 126 healthy patients aged 17-25 years. Participants were divided into three groups based on growth patterns: average, vertical, and horizontal. Dermatoglyphic patterns were recorded using an optical fingerprint sensor, and palatal characteristics were measured using digital software. Palatal characteristics, including intercanine width, intermolar width, and palatal depth, were measured using digital software. The results were statistically analyzed. RESULTS Significant differences were observed in ridge counts among the three growth patterns. The average growth pattern showed lower ridge counts compared to the vertical and horizontal growth patterns. Dermatoglyphic patterns, such as double loops and tented arches, were significantly higher in the horizontal growth pattern. Weak correlations were found between certain dermatoglyphic patterns and palatal characteristics, with simple arch patterns showing a negative correlation with inter-canine width and symmetrical whorl patterns showing a positive correlation with palatal depth. Loop patterns, spiral patterns, double loop patterns, symmetrical whorl, and simple arch patterns were significant predictors of growth patterns. CONCLUSION This study revealed distinct dermatoglyphic patterns and ridge counts among individuals with different growth patterns. Weak correlations were observed between dermatoglyphic patterns and palatal characteristics. However, the predictive value of dermatoglyphics for skeletal malocclusion requires further investigation. Understanding the relationships between dermatoglyphic patterns and craniofacial growth can provide valuable insights into genetic and developmental factors affecting dental and orthodontic conditions.

Abstract
Aging-related abnormalities in gut microbiota are associated with cognitive decline, depression, and anxiety, but underlying mechanisms remain unstudied. Here, our study demonstrated that transplanting old gut microbiota to young mice induced inflammation in the gut and brain coupled with cognitive decline, depression, and anxiety. We observed diminished mucin formation and increased gut permeability ("leaky gut") with a reduction in beneficial metabolites like butyrate because of decline in butyrate-producing bacteria in the aged gut microbiota. This led to suppressed expression of butyrate receptors, free fatty acid receptors 2 and 3 (FFAR2/3). Administering butyrate alleviated inflammation, restored mucin expression and gut barriers, and corrected brain dysfunction. Furthermore, young mice with intestine-specific loss of FFAR2/3 exhibited gut and brain abnormalities akin to those in older mice. Our results demonstrate that reduced butyrate-producing bacteria in aged gut microbiota result in low butyrate levels and reduced FFAR2/3 signaling, leading to suppressed mucin formation that increases gut permeability, inflammation, and brain abnormalities. These findings underscore the significance of butyrate-FFAR2/3 agonism as a potential strategy to mitigate aged gut microbiota-induced detrimental effects on gut and brain health in older adults.

Abstract
AIMS Cardiac disease is a dose-limiting toxicity in non-small cell lung cancer radiotherapy. The dose to the heart base has been associated with poor survival in multiple institutional and clinical trial datasets using unsupervised, voxel-based analysis. Validation has not been undertaken in a cohort with individual patient delineations of the cardiac base or for the endpoint of cardiac events. The purpose of this study was to assess the association of heart base radiation dose with overall survival and the risk of cardiac events with individual heart base contours. MATERIALS AND METHODS Patients treated between 2015 and 2020 were reviewed for baseline patient, tumour and cardiac details and both cancer and cardiac outcomes as part of the NI-HEART study. Three cardiologists verified cardiac events including atrial fibrillation, heart failure and acute coronary syndrome. Cardiac substructure delineations were completed using a validated deep learning-based autosegmentation tool and a composite cardiac base structure was generated. Cox and Fine-Gray regressions were undertaken for the risk of death and cardiac events. RESULTS Of 478 eligible patients, most received 55 Gy/20 fractions (96%) without chemotherapy (58%), planned with intensity-modulated radiotherapy (71%). Pre-existing cardiovascular morbidity was common (78% two or more risk factors, 46% one or more established disease). The median follow-up was 21.1 months. Dichotomised at the median, a higher heart base Dmax was associated with poorer survival on Kaplan-Meier analysis (20.2 months versus 28.3 months; hazard ratio 1.40, 95% confidence interval 1.14-1.75, P = 0.0017) and statistical significance was retained in multivariate analyses. Furthermore, heart base Dmax was associated with pooled cardiac events in a multivariate analysis (hazard ratio 1.75, 95% confidence interval 1.03-2.97, P = 0.04). CONCLUSIONS Heart base Dmax was associated with the rate of death and cardiac events after adjusting for patient, tumour and cardiovascular factors in the NI-HEART study. This validates the findings from previous unsupervised analytical approaches. The heart base could be considered as a potential sub-organ at risk towards reducing radiation cardiotoxicity.

Abstract
PURPOSE The ADRRAD trial reported the safety and feasibility of the combination of external beam radiotherapy and radium-223 in the treatment of de novo bone metastatic prostate. This study aimed to determine if any biomarkers predictive of response to these treatments could be identified. EXPERIMENTAL DESIGN 30 patients with newly diagnosed bone metastatic hormone sensitive prostate cancer were recruited to the ADRRAD trial. Blood samples were taken pre-treatment, before cycles 2 to 6 of radium-223, and 8 weeks and 6 months after treatment. Mononuclear cells were isolated and DNA damage was assessed at all timepoints. RESULTS DNA damage was increased in all patients during treatment, with bigger increases in foci observed in patients who relapsed late compared to those who relapsed early. Increases in DNA damage during the radium-223 only cycles of treatment were specifically related to response in these patients. Analysis of hematology counts also showed bigger decreases in red blood cell and hemoglobin counts in patients who experienced later biochemical relapse. CONCLUSIONS While some patients responded to this combination treatment, others relapsed within one year of treatment initiation. This study identifies a biomarker based approach that may be useful in predicting which patients will respond to treatment, by monitoring both increases in DNA damage above baseline levels in circulating lymphocytes and decreases in red blood cell and hemoglobin counts during treatment.

Abstract
Aging is associated with cellular and physiological changes, which significantly reduce the quality of life and increase the risk for disease. Geroprotectors improve lifespan and slow the progression of detrimental aging-related changes such as immune system senescence, mitochondrial dysfunction, and dysregulated nutrient sensing and metabolism. Emerging evidence suggests that gut microbiota dysbiosis is a hallmark of aging-related diseases and microbiome modulators, such as probiotics (live bacteria) or postbiotics (non-viable bacteria/bacterial byproducts) may be promising geroprotectors. However, because they are strain-specific, the geroprotective effects of probiotics and postbiotics remain poorly understood and understudied. Drosophila melanogaster, Caenorhabditis elegans, and rodents are well-validated preclinical models for studying lifespan and the role of probiotics and/or postbiotics, but each have their limitations, including cost and their translation to human aging biology. C. elegans is an excellent model for large-scale screening to determine the geroprotective potential of drugs or probiotics/postbiotics due to its short lifecycle, easy maintenance, low cost, and homology to humans. The purpose of this article is to review the geroprotective effects of microbiome modulators and their future scope, using C. elegans as a model. The proposed geroprotective mechanisms of these probiotics and postbiotics include delaying immune system senescence, preventing or reducing mitochondrial dysfunction, and regulating food intake (dietary restriction) and metabolism. More studies are warranted to understand the geroprotective potential of probiotics and postbiotics, as well as other microbiome modulators, like prebiotics and fermented foods, and use them to develop effective therapeutics to extend lifespan and reduce the risk of debilitating aging-related diseases.

Abstract
Short-chain fatty acids (SCFAs) are key nutrients that play a diverse set of roles in physiological function, including regulating metabolic homeostasis. Generated through the fermentation of dietary fibers in the distal colon by the gut microbiome, SCFAs and their effects are partially mediated by their cognate receptors, including free fatty acid receptor 2 (FFA2). FFA2 is highly expressed in the intestinal epithelial cells, where its putative functions are controversial, with numerous in vivo studies relying on global knockout mouse models to characterize intestine-specific roles of the receptor. Here, we used the Villin-Cre mouse line to generate a novel, intestine-specific knockout mouse model for FFA2 (Vil-FFA2) to investigate receptor function within the intestine. Because dietary changes are known to affect the composition of the gut microbiome, and can thereby alter SCFA production, we performed an obesogenic challenge on male Vil-FFA2 mice and their littermate controls (FFA2-floxed, FFA2fl/fl) to identify physiological changes on a high-fat, high-sugar 'Western diet' (WD) compared to a low-fat control diet (CD). We found that the WD-fed Vil-FFA2 mice were transiently protected from the obesogenic effects of the WD and had lower fat mass and improved glucose homeostasis compared to the WD-fed FFA2fl/fl control group during the first half of the study. Additionally, major differences in respiratory exchange ratio and energy expenditure were observed in the WD-fed Vil-FFA2 mice, and food intake was found to be significantly reduced at multiple points in the study. Taken together, this study uncovers a novel role of intestinal FFA2 in mediating the development of obesity.

Abstract
Alzheimer's disease (AD) is a progressive, age-related neurodegenerative disorder that affects a large proportion of the older population. It currently lacks effective treatments, placing a heavy burden on patients, families, health care systems, and society. This is mainly due to our limited comprehension of the pathophysiology of AD progression, as well as the lack of effective drug targets and intervention timing to address the underlying pathology. AD is a multifactorial condition, and emerging evidence suggests that abnormalities in the gut microbiota play a significant role as environmental and multifaceted contributors to AD, although the exact mechanisms are yet to be fully explored. Changes in the composition of microbiota influence host neuronal health through their metabolites. These metabolites regulate intestinal epithelia, blood-brain barrier permeability, and neuroinflammation by affecting mitochondrial function. The decline in the proportion of beneficial microbes and their essential metabolites during aging and AD is directly linked to poor mitochondrial function, although the specific mechanisms remain unclear. In this review, we discuss recent developments in understanding the impact of the microbiome and its metabolites on various cell types, their influence on the integrity of the gut and blood-brain barriers, systemic and brain inflammation, and cell-specific effects in AD pathology. This information is expected to pave the way for a new understanding of the interactions between microbiota and mitochondria in AD, providing a foundation for the development of novel treatments for AD.

Abstract
Alzheimer's disease (AD) is a multifactorial neurodegenerative disease characterized by cognitive and behavioral changes in older adults. Emerging evidence suggests poor oral health is associated with AD, but there is a lack of large-scale clinical studies demonstrating this link. Herein, we used the TriNetX database to generate clinical cohorts and assess the risk of AD and survival among >30 million de-identified subjects with normal oral health (n = 31,418,814) and poor oral health (n = 1,232,751). There was a greater than two-fold increase in AD risk in the poor oral health cohort compared to the normal oral health group (risk ratio (RR): 2.363, (95% confidence interval: 2.326, 2.401)). To reduce potential bias, we performed retrospective propensity score matching for age, gender, and multiple laboratory measures. After matching, the cohorts had no significant differences in survival probability. Furthermore, when comparing multiple oral conditions, diseases related to tooth loss were the most significant risk factor for AD (RR: 3.186, (95% CI: 3.007, 3.376)). Our results suggest that oral health may be important in AD risk, regardless of age, gender, or laboratory measures. However, more large-scale cohort studies are necessary to validate these findings and further evaluate links between oral health and AD.

Abstract
Informal discussion regarding surgical management plans between strabismus surgeons is common but this limits potentially valuable multi-disciplinary input and learning opportunities. We evaluate the effectiveness of virtual multidisciplinary meetings to provide a platform for discussion of pre-operative strabismus surgical cases.Weekly virtual MS Teams meetings are held on Monday mornings for one hour, attended by the three paediatric consultants, paediatric fellow, all trainees on the paediatric firm and orthoptists. The meetings are recorded and available for reference to the content and for those not present.Presentations for upcoming surgery cases are prepared and presented by the fellow, with discussion from participants regarding examination findings and surgical options. Cases are anonymised to allow multicentre collaboration. The agreed management plan is documented in the patient's medical notes, and outcomes of challenging cases are discussed.The management plan is formalised during the MDT. Where required, additional tests are arranged. There are opportunities for all participants to constructively challenge decisions. Trainees of all levels are actively engaged by presenting, listening to the rationale behind surgical plans, with the opportunity to ask and respond to questions.Patients are informed that their case has been presented in the MDT to obtain multiple opinions, which gives them additional confidence. Orthoptists can see the impact of the measurements they provide, and how differing tests can change management plans.This MDT has been a positive change to our surgical strabismus patient pathway. Knowledge and teamwork have been strengthened using this innovative virtual discussion method.

Abstract
PURPOSE/OBJECTIVE(S) Radiation cardiotoxicity is a significant clinical dilemma in non-small cell lung cancer (NSCLC) radiation therapy (RT). Baseline cardiovascular (CV) status may influence the risk of cardiotoxicity, and may be ascertainable from the appearance of the heart on simulation computed tomography (CT). We examined the association of CT features with incidental heart dose and risk of cardiac events in NSCLC. MATERIALS/METHODS Patients treated with curative-intent RT between 2015 and 2020 at a regional center were identified. Clinical notes were interrogated for baseline patient and CV health details, and follow-up CV events. Cardiac events were verified by a cardiologist. A deep learning-based auto-segmentation tool was applied, allowing extraction of a pre-specified list of volume parameters in a programming environment. CAC was graded as none, mild, moderate and severe in patients with a non-contrast scan. The craniocaudal relationship of the PTV and heart (Feng atlas) were annotated. RESULTS A total of 478 patients were included, with a median age of 70 and Charlson Index of 5. The median mean heart dose was 6.3 Gy (IQR 2.7-11.4). The median lung V20 was 20.0% (IQR 14.8-27.1). Cardiovascular risk factors were common, with most patients having 2 (39%) or 3 (31%). A history of previous cardiac events was common, including myocardial infarction (14%), arrhythmia (11%) or heart failure (9%). A total of 6.9% and 7.1% patients developed a new atrial arrhythmia (AA) or heart failure (HF) after completing RT. The volume metrics with the highest AUC for AA and HF events were the left atrium (LA) (AUC 0.67, p = 0.0002) and left ventricle:right ventricle (LV:RV) ratio (AUC 0.66, p = 0.0021). Kaplan-Meier analysis for cardiac events dichotomizing at the optimal cut-point for maximum sensitivity and specificity demonstrated significantly different rates for both AA (LA 109cc, HR 3.35, 95% CI 1.64-6.83, p = 0.0009) and HF (LV:RV ratio 1.61, HR 2.37, 95% CI 1.19-4.74, p = 0.0143). Only 2 patients with non-contrast scans developed a myocardial infarction, both had mild CAC. The incidence of pooled cardiac events was not significantly different between patients with no (n = 2/21, 9.5%), mild (n = 10/38, 26.3%), moderate (n = 8/53, 15.1%) and severe (n = 7/24, 29.2%) CAC (p = 0.3916). Where the inferior border of the PTV was above the superior border of the heart, mean heart dose was significantly lower than compared with overlap of levels (1.9 Gy v 9.7 Gy, p<0.0001), and this was true for 3DCRT (n = 139, p<0.001), IMRT (n = 94, p<0.001) and VMAT (n = 145, p<0.001) patients. CONCLUSION LA volume and LV:RV volume ratio are predictive for the development of AA and HF respectively. CAC grade did not differentiate patients by risk of cardiac events. Where the craniocaudal level of the PTV doesn't overlap with the level of the heart, the cardiac dose is likely to be very low. Several simulation CT features are associated with cardiac events following treatment for NSCLC and prospective evidence of cardiac risk could enable medical optimization prior to RT.

Abstract
OBJECTIVE Ample evidence exists for the role of abnormal gut microbiota composition and increased gut permeability ('leaky gut') in chronic inflammation that commonly co-occurs in the gut in both obesity and diabetes, yet the detailed mechanisms involved in this process have remained elusive. DESIGN In this study, we substantiate the causal role of the gut microbiota by use of faecal conditioned media along with faecal microbiota transplantation. Using untargeted and comprehensive approaches, we discovered the mechanism by which the obese microbiota instigates gut permeability, inflammation and abnormalities in glucose metabolism. RESULTS We demonstrated that the reduced capacity of the microbiota from both obese mice and humans to metabolise ethanolamine results in ethanolamine accumulation in the gut, accounting for induction of intestinal permeability. Elevated ethanolamine increased the expression of microRNA-miR-101a-3p by enhancing ARID3a binding on the miR promoter. Increased miR-101a-3p decreased the stability of zona occludens-1 (Zo1) mRNA, which in turn, weakened intestinal barriers and induced gut permeability, inflammation and abnormalities in glucose metabolism. Importantly, restoring ethanolamine-metabolising activity in gut microbiota using a novel probiotic therapy reduced elevated gut permeability, inflammation and abnormalities in glucose metabolism by correcting the ARID3a/miR-101a/Zo1 axis. CONCLUSION Overall, we discovered that the reduced capacity of obese microbiota to metabolise ethanolamine instigates gut permeability, inflammation and glucose metabolic dysfunctions, and restoring ethanolamine-metabolising capacity by a novel probiotic therapy reverses these abnormalities.

Abstract
β-Thalassemia major is an inherited blood condition marked by a serious anemia and a lifetime need for blood transfusions. The effects of β-thalassemia major on endocrine health, notably the risk of diabetes, remain largely unstudied, despite the fact that its haematological components are established. The purpose of this systematic analysis was to examine the incidence of reduced metabolism of glucose in β--thalassemia major. The articles were under the inclusion requirements, after which the data was retrieved. The main outcome was determined to be every prevalence (P) of DM (diabetes mellitus) in β-thalassemia major. In order to examine the percentage of aberrant glucose metabolism (GM) with individuals among β-thalassemia major, the P with the 95% CI (Confidence Interval) was utilized. In this retrospective investigation, we looked at a cohort of people with β-thalassemia major diagnoses to determine the incidence and risk of hormonal diseases, particularly diabetes. A specialist thalassemia facility treated 315 individuals with β-thalassemia major, and their medical records were examined. Age, gender, age at which a main diagnosis of β-thalassemia was made, the length of transfusion treatment, and concomitant diseases were gathered as part of the demographic and clinical data. Our research, which included 17 studies and 1500 cases altogether, showed that with β -thalassemia major had a considerably greater frequency of diabetes than people in general. With a mean beginning age of 30 years, diabetes was identified in 28% of the research cohort's participants. The combined meta-analysis showed that each year had a rather stable level of DM P in β-thalassemia major. In people with major β-thalassemia, the P of impaired fasting glucose (IFG), DM, and impaired glucose tolerance (IGT) was 17.22% (95% CI: 8.44%-26.02%), (6.57 (95% CI: 5.31%- 7.79%) and 12.47 % (95% CI: 5.97%-18.95%), respectively. Our research suggests that people with β-thalassemia major have a high chance of acquiring diabetes, particularly if they get extended transfusion treatment. For prompt diagnosis and care, early detection of diabetes and other hormonal problems in this group is crucial. In β-thalassemia major, there is a high frequency of endocrine problems, including improper GM. To stop growth and endocrine issues, treatment and preventative measures can be required.

Abstract
Patients and their Families undergoing Strabismus Surgery. The aim of this study was to develop a questionnaire to identify perioperative fear and anxiety factors affecting pediatric strabismus surgery patients.First, we reviewed the literature to determine precipitants of fears and anxieties experienced by pediatric patients. Subsequently, we developed a questionnaire for pediatric patients undergoing strabismus surgery. This was a two part questionnaire, consisting of a 16-piece section for patients and a 22-piece section for parents. Finally, we piloted this questionnaire to validate its clinical use.Common anxiety factors for children include pain, minor clinical procedures requiring needles, separation from parents and engaging with medical professionals. We used this information to develop a two part questionnaire for patients and parents. The questionnaire elicited positive and negative aspects of the patient journey, corroborated fears reported in the literature, and identified anxiety inducing factors specific to strabismus patients.There is a lack of evidence regarding fear and anxiety specific to pediatric ophthalmology surgeries. Strabismus surgery carries unique fear inducing factors. Interventions which may alleviate the stress of pediatric surgery, therefore greatly benefit patient experience and surgical outcomes, and should be considered in the care of pediatric patients. Patient educational material is known to provide a sense of control to patients, helping to alleviate such fear.Evidenced by the literature and the pilot questionnaire, there still exists anxiety inducing factors in pediatric surgery. Investigation into patient fears regarding pediatric strabismus surgery is needed to better understand how clinical staff can support patients perioperatively.

Abstract
The prevalence of age-related cognitive disorders/dementia is increasing, and effective prevention and treatment interventions are lacking due to an incomplete understanding of aging neuropathophysiology. Emerging evidence suggests that abnormalities in gut microbiome are linked with age-related cognitive decline and getting acceptance as one of the pillars of the Geroscience hypothesis. However, the potential clinical importance of gut microbiome abnormalities in predicting the risk of cognitive decline in older adults is unclear. Till now the majority of clinical studies were done using 16S rRNA sequencing which only accounts for analyzing bacterial abundance, while lacking an understanding of other crucial microbial kingdoms, such as viruses, fungi, archaea, and the functional profiling of the microbiome community. Utilizing data and samples of older adults with mild cognitive impairment (MCI; n = 23) and cognitively healthy controls (n = 25). Our whole-genome metagenomic sequencing revealed that the gut of older adults with MCI harbors a less diverse microbiome with a specific increase in total viruses and a decrease in bacterial abundance compared with controls. The virome, bacteriome, and microbial metabolic signatures were significantly distinct in subjects with MCI versus controls. Selected bacteriome signatures show high predictive potential of cognitive dysfunction than virome signatures while combining virome and metabolic signatures with bacteriome boosts the prediction power. Altogether, the results from our pilot study indicate that trans-kingdom microbiome signatures are significantly distinct in MCI gut compared with controls and may have utility for predicting the risk of developing cognitive decline and dementia- debilitating public health problems in older adults.

Abstract
PURPOSE/OBJECTIVE(S) Cardiac disease is a dose-limiting toxicity in non-small cell lung cancer (NSCLC) radiation therapy. Radiation dose to the cardiac base is associated with poor overall survival in several clinical studies, but has not been validated in a non-dose escalated cohort, or with individual patient delineations. In this study we examined the impact of cardiac base dose on overall survival (OS) and cardiac events (CEs), and interrogated the relationships of the substructures comprising the heart base with OS and CEs. MATERIALS/METHODS Patients with stage I-III NSCLC treated with curative-intent radiation therapy between 2015 and 2020 at a regional cancer center were identified. Clinical notes were examined for baseline patient, tumor and cardiac details, and both cancer and cardiac outcomes. Three cardiologists verified CEs. Cardiac delineations were completed using a validated deep learning-based autosegmentation tool. Cox and Fine and Gray regressions were undertaken for the risk of death and CEs respectively, accounting for pre-specified evidence-based dose metrics and clinically relevant cardiac covariates. RESULTS Most patients received 55 Gy/20# (n = 461/478, 96%) without chemotherapy (58%), planned with VMAT (51%) or IMRT (20%). Pre-existing cardiovascular morbidity was common, with 78% having ≥2 risk factors, and 46% having >1 established cardiac disease. The median follow-up was 21.1 months. Dichotomized at the median, higher heart base Dmax was associated with poorer survival on Kaplan-Meier analysis (21.6 months (95% CI 19.3-24.9) versus 29.4 months (95% CI 21.6-36.6), p = 0.021), and remained significant when statistically compared in published multivariate models. In a multivariate analysis for pooled acute CEs, heart base Dmax was associated with CEs (HR 1.75, 95% CI 1.01-1.06, p = 0.04), but this was not the case for individual CEs. Using Fine and Gray models to account for the competing risk of death, left main coronary maximum dose was associated with atrial fibrillation (p = 0.024), proximal right coronary artery V15 (p = 0.023) and mean dose (p = 0.032), and the right atrium mean dose (p = 0.029) were associated with heart failure. No dose-volume metrics were significantly associated with acute coronary syndrome. None of the constituent base substructures dose were significantly associated with death. CONCLUSION Dose to the heart base was associated with increased mortality and an increased pooled cardiac event rate. Accounting for endpoint-specific clinical covariates, only select constituent substructures of the heart base were associated with CEs and no substructures were independently associated with survival. Together, these findings are suggestive of possible interplay between the constituent base substructures in their mediation of radiation cardiotoxicity.

Abstract
Context The COVID-19 pandemic and subsequent lockdowns adversely affected global healthcare services to varying extents. To accommodate its added burden, emergency services were affected along-with elective surgeries. Aims To quantify and analyze the trends of essential surgeries and bellwether procedures during the waxing and waning of the pandemic, across various hospitals in India. Settings and Design Multi-centric retrospective study. Methods and Material A research consortium led by World Health Organization (WHO) Collaboration Center (WHOCC) for Research in Surgical Care Delivery in Low-and Middle-Income countries, India, conducted this study with 5 centers. All surgeries performed during April 2020 (Wave I), November 2020 (Recovery I), and April 2021 (Wave II) were compared with those performed in April 2019 (pre-pandemic period). Statistical Analysis Used Microsoft Excel 2019 and SPSS Version 20. Results The total number of surgeries reduced by 77% during Wave I, which improved to a 52% reduction in Recovery I compared to the pre-pandemic period. However, surgeries were reduced again during Wave II to 68%, but the reduction was less compared to Wave I. Emergency and essential surgeries were affected along with the elective ones but to a lesser extent. Conclusions The present study has quantified the effects of the pandemic on surgical-care delivery across a timeline and documented a reduction in overall surgical volumes during the peaks of the pandemic (Wave I and II) with minimal improvement as the surge of COVID-19 cases declined (Recovery II). The surgical volumes improved during the second wave compared to the first one which may be attributable to better preparedness. Cesarean sections were affected the least.

Abstract
Purpose. Commercial electron FLASH platforms deliver ultra-high dose rate doses at discrete combinations of pulse parameters including pulse width (PW), pulse repetition frequency (PRF) and number of pulses (N), which dictate unique combinations of dose and dose rates. Additionally, collimation, source to surface distance, and airgaps also vary the dose per pulse (DPP). Currently, obtaining pulse parameters for the desired dose and dose rate is a cumbersome manual process involving creating, updating, and looking up values in large spreadsheets for every treatment configuration. This work presents a pulse parameter optimizer application to match intended dose and dose rate precisely and efficiently.Methods. Dose and dose rate calculation methods have been described for a commercial electron FLASH platform. A constrained optimization for the dose and dose rate cost function was modelled as a mixed integer problem in MATLAB (The MathWorks Inc., Version9.13.0 R2022b, Natick, Massachusetts). The beam and machine data required for the application were acquired using GafChromic film and alternating current current transformers (ACCTs). Variables for optimization included DPP for every collimator, PW and PRF measured using ACCT and airgap factors.Results. Using PW, PRF,Nand airgap factors as parameters, a software was created to optimize dose and dose rate, reaching the closest match if exact dose and dose rates are not achievable. Optimization took 20 s or less to converge to results. This software was validated for accuracy of dose calculation and precision in matching prescribed dose and dose rate.Conclusion. A pulse parameter optimization application was built for a commercial electron FLASH platform to increase efficiency in dose, dose rate, and pulse parameter prescription process. Automating this process reduces safety concerns associated with manual look up and calculation of these parameters, especially when many subjects at different doses and dose rates are to be safely managed.

Abstract
Intramedullary Titanium elastic nailing (TENS) is successfully used for irreducible and displaced forearm bone fractures in children. The purpose of this study was to report the potential complications and functional outcomes associated with paediatric forearm fractures treated with TENS nails. We retrospectively reviewed 65 children with displaced forearm bone fractures treated by TENS nailing with a mean follow-up of 5.84 months (4-12). Data detailing patient demographics, fracture characteristics, associated fractures, injury surgery interval, grade of the operating surgeon, methods of fixation, time to union, the timing of removal of the nail, and complications were collected and analysed. The mean age in our study was 9.13 years. 92% had fractures of both radius and ulna, 83.3% had fixation of both bones, and 16.7% had single bone fixation only. Open reduction was required in 38.5% of cases. The average time to fracture union was 10.34 weeks (6-20). The average time of implant removal was 20.12 weeks (9-32). We observed an overall complication rate of 41.5%. We noted a higher (56% vs 32.5%, p=0.059) complication rate in open reduction cases. According to the Price criteria, we had excellent to good results in over 98% of patients despite a slightly higher complication rate. Titanium elastic nailing is a safe, reliable method of internal fixation for irreducible or unstable fractures of both bones of the forearm in children. Open reduction of fracture was associated with higher complications. Despite higher overall complications, we noted excellent functional results in most cases.

Abstract
As we age, our organ functions gradually decline. Circulating factors in the blood and the integrity of organ barriers can become dysfunctional, resulting in a condition known as leaky syndrome. This condition involves the unregulated exchange or leakage of components between organs. However, the triggers of leaky syndrome, as well as its role in aging-related disorders and illnesses, remain largely unknown. In this editorial, we discuss potential mechanisms that originate from the gut and resident microbes (microbiome) to contribute in leaky syndrome. Furthermore, we explore how the food we consume can impact the development of leaky syndrome, potentially influencing the biology of aging and challenges to diagnose the leaky gut condition accurately and clinically.

Abstract
Splenic cysts are rare; their absence of an epithelial wall determines whether they're real cysts or pseudocysts. Spontaneous nonparasitic actual tumors are those that develop early in life at the anterior pole of the splenic and are typically epidermoid, dermoid, or endodermal. Surgical therapy is suggested for symptomatic, large (more than 5 cm) cysts or complicated. Inhaling splenic excision is a substitute for surgery, depending on the quantity, location, connection to the hilus, and dimension of the tumors. With an emphasis on less invasive treatments that preserve the spleen, laparoscopic methods have already established themselves as the accepted method for treating numerous disorders, including splenic cysts. They describe the effective decapsulation of a massive epidermoid spleen tumor under a prolonged, partially endoscopic technique. Laparoscopy, an operation commonly referred to as surgery with minimally invasive or keyhole surgery, is a technique that makes many tiny incisions in the belly to carry out different surgical procedures.

Abstract
The field of Global Mental Health (GMH) aims to address the global burden of mental illness by focusing on closing the "treatment gap" faced by many low- and middle-income countries (LMICs). To increase access to services, GMH prioritizes "scaling up" mental health services, primarily advocating for the export of Western centred and developed biomedical and psychosocial "evidence-based" approaches to the Global South. While this emphasis on scalability has resulted in the increased availability of mental health services in some LMICs, there have been few critical discussions of this strategy. This commentary critically appraises the scalability of GMH by questioning the validity and sustainability of its approach. We argue that the current approach emphasizes the development of mental health services and interventions in "silos," focusing on the treatment of mental illnesses at the exclusion of a holistic and contextualized approach to people's needs. We also question the opportunities that the current approach to GMH offers for the growth of mental health programmes of local NGOs and investigate the potential pitfalls that scalability may have on NGOs' impact and ability to innovate. This commentary argues that any "scaling up" of mental health services must place sustainability at the core of its mission by favouring the growth and development of local solutions and wider forms of support that prioritize social inclusion and long-lasting mental health recovery.

Abstract
Sleep is a fundamental medicine for cardiac homeostasis, and sleep-deprived individuals are prone to higher incidences of heart attack. The lipid-dense diet (obesogenic diet-OBD) is a cumulative risk factor for chronic inflammation in cardiovascular disease; thus, understanding how sleep fragmentation (SF) in an obesity setting impacts immune and cardiac health is an unmet medical need. We hypothesized whether the co-existence of SF with OBD dysregulates gut homeostasis and leukocyte-derived reparative/resolution mediators, thereby impairing cardiac repair. Two-month-old male C57BL/6J mice were randomized first into two groups, then four groups; Control, control + SF, OBD, and OBD + SF mice subjected to myocardial infarction (MI). OBD mice had higher levels of plasma linolenic acid with a decrease in eicosapentaenoic and docosahexaenoic acid. The OBD mice had lower Lactobacillus johnsonii indicating a loss of probiotic microbiota. SF in OBD mice increased Firmicutes/Bacteroidetes ratio indicative of a detrimental change in SF-directed microbiome. OBD + SF group increased in the neutrophil: lymphocyte ratio suggestive of suboptimal inflammation. As a result of SF, resolution mediators (RvD2, RvD3, RvD5, LXA4 , PD1, and MaR1) decreased and inflammatory mediators (PGD2 , PGE2 , PGF2a , 6k-PGF1a ) were increased in OBD mice post-MI. At the site of infarction, the proinflammatory cytokines Ccl2, IL1β, and IL-6 were amplified in OBD + SF indicating a robust proinflammatory milieu post-MI. Also, brain circadian genes (Bmal1, Clock) were downregulated in SF-subjected control mice, but remained elevated in OBD mice post-MI. SF superimposed on obesity dysregulated physiological inflammation and disrupted resolving response thereby impaired cardiac repair and signs of pathological inflammation.

Abstract
BACKGROUND Preterm birth or low birth weight is the single largest cause of death in newborns, however this mortality can be reduced through newborn care interventions, including Kangaroo Mother Care (KMC). Previously, a multi-country randomized controlled trial, coordinated by the World Health Organization (WHO), reported a significant survival advantage with initiation of continuous KMC immediately after birth compared with initiation of continuous KMC a few days after birth when the baby is considered clinically stable. Whether the survival advantage would lead to higher rates of neurodevelopmental morbidities, or the immediate KMC will also have a beneficial effect on cognitive development also, has not been investigated. We therefore propose to test the hypothesis that low-birth-weight infants exposed to immediate KMC will have lower rates of neurodevelopmental impairment in comparison to traditional KMC-treated infants, by prospectively following up infants already enrolled in the immediate KMC trial for the first 2 years of life, and assessing their growth and neurodevelopment. METHODS This prospective cohort study will enroll surviving neonates from the main WHO immediate KMC trial. The main trial as well as this follow-up study are being conducted in five low- and middle-income countries in South Asia and sub-Saharan Africa. The estimated sample size for comparison of the risk of neurodevelopmental impairment is a total of 2200 children. The primary outcome will include rates of cerebral palsy, hearing impairment, vision impairment, mental and motor development, and epilepsy and will be assessed by the age of 3 years. The analysis will be by intention to treat. DISCUSSION Immediate KMC can potentially reduce low-birth-weight-associated complications such as respiratory disease, hypothermia, hypoglycemia, and infection that can result in impaired neurocognitive development. Neuroprotection may also be mediated by improved physiological stabilization that may lead to better maturation of neural pathways, reduced risk of hypoxia, positive parental impact, improved sleep cycles, and improved stress responses. The present study will help in evaluating the overall impact of KMC by investigating the long-term effect on neurodevelopmental impairment in the survivors.

Abstract
Background Preoperative anxiety is an important, yet often unattended problem in children. Minimizing anxiety and distress at the time of anesthetic induction may reduce adverse psychological and physiological outcomes. Sedative premedication and parental presence during anesthesia induction are among the most commonly employed strategies for reducing child anxiety. Aims and Objective The study aimed to compare the effectiveness of a pharmacological intervention (premedication with midazolam) versus behavioral intervention (parental presence) in reducing preoperative anxiety in children undergoing general anesthesia. Methodology Sixty patients of age group of 4-12 years, of ASA Grade 1 and 2 and either sex posted for elective surgery under general anesthesia were divided into two groups of 30 each Group M (midazolam group) and Group P (parental presence). Group M received intravenous midazolam 0.03-0.05 mg/kg preoperatively and anxiety was measured in preoperative room, during separation from parents and during introduction of anesthesia mask, whereas in Group P, parents accompanied the child inside the operation theater and anxiety was measured at preoperative room and during introduction of mask. Parental anxiety was measured in both groups at preoperative room and waiting room. Modified Yale Preoperative Anxiety Scale (mYPAS) and State Trait Anxiety Inventory (STAI) tool was used to measure anxiety in children and parents, respectively. Results The mean mYPAS score while the introduction of anesthesia mask in Group M was 31.30 ± 12.04 and in Group P was 63.19 ± 25.31, and the difference was found to be statistically significant (P = 0.001). In preoperative room, there was no significant difference in anxiety in the two study groups. The mean STAI score in Group P was 45.63 ± 1.45 and in Group M was 41.10 ± 1.69, and the difference was found to be statistically significant (P = 0.001). In preoperative room, parental anxiety was found to be comparable among the two groups. The mean duration of induction of anesthesia in Group M was 5.53 ± 1.01 min, and in Group P, it was 8.77 ± 2.03 min. The difference was found to be statistically significant (P = 0.001). Conclusion Both interventions were effective in reducing anxiety in children, but midazolam was more effective compared to parental presence. Parents in Group M were less anxious in the waiting room than Group P. Children in Group M were more compliant during the induction of anesthesia, hence a lesser duration of induction than Group P.

Abstract
Intermittent Fasting (IF) is the consumption of food and drinks within a defined time, while the ketogenic diet (KD) switches the metabolism from glucose to fats. Continuation of intermittent fasting leads to the generation of ketones, the exact mechanism for a ketogenic diet. This article discusses the types of IF and KD, the monitoring required, and the mechanisms underlying IF and KD, followed by disorders in which the combination strategy could be applied. The strategies for successfully applying combination therapy are included, along with recommendations for the primary care physicians (PCP) which could serve as a handy guide for patient management. This opinion article could serve as the baseline for future clinical studies since there is an utmost need for developing new wholesome strategies for managing chronic disorders.

Abstract
Disclosure summary Dr. Yadav is Chief Scientific Officer and Co-Founder of Postbiotics Inc and has no conflict of interest with this work. All other authors have no conflicts of interest to disclose. Background Metformin is the only approved first-line oral glucose lowering agent for youth with type 2 diabetes mellitus (Y-T2DM) but often causes gastrointestinal (GI) side effects, which may contribute to reduced treatment adherence and efficacy. Prebiotic intake may reduce metformin's side effects by shifting microbiota composition and activity. Objective The aims of this study were to determine the feasibility and tolerability of a prebiotic supplement to improve metformin-induced GI symptoms and explore the changes in glycemia and shifts in the microbiota diversity. Methods In a two-phase pilot clinical trial, we compared, stool frequency and stool form every 1-2 days, and composite lower GI symptoms (weekly) at initiation of daily metformin combined with either a daily prebiotic or a placebo shake in a 1-week randomized double-blind crossover design (Phase 1), followed by a 1-month open-labeled extension (Phase 2). Plasma glycemic markers and stool samples were collected before and after each phase. Results Six Y-T2DM (17.2 ± 1.7y (mean ± SD), 67% male, BMI (42 ± 9 kg/m2), HbA1c (6.4 ± 0.6%)) completed the intervention. Stool frequency, stool composition, and GI symptom scores did not differ by group or study phase. There were no serious or severe adverse events reported, and no differences in metabolic or glycemic markers. After one week Phase 1metformin/placebo Proteobacteria, Enterobacteriaceae, and Enterobacteriales were identified as candidate biomarkers of metformin effects. Principle coordinate analyses of beta diversity suggested that the metformin/prebiotic intervention was associated with distinct shifts in the microbiome signatures at one week and one month. Conclusion Administration of a prebiotic fiber supplement during short-term metformin therapy was well tolerated in Y-T2DM and associated with modest shifts in microbial composition. This study provides a proof-of-concept for feasibility exploring prebiotic-metformin-microbiome interactions as a basis for adjunctive metformin therapy.

Abstract
AIM This study aims to evaluate costs associated with periprosthetic femoral fracture (PFF) treatment at a UK tertiary referral centre. METHODS This study included 128 consecutive PFFs admitted from 02/04/2014-19/05/2020. Financial data were provided by Patient Level Information and Costing Systems. Primary outcomes were median cost and margin. Secondary outcomes were length of stay, blood transfusion, critical care, 30-day readmission, 2-year local complication, 2-year systemic complication, 2-year reoperation and 30-day mortality rates. Statistical comparisons were made between treatment type. Statistical significance was set at p<0.05. RESULTS Across the cohort, median cost was £15,644.00 (IQR £11,031.00-£22,255.00) and median loss was £3757.50 (£599.20-£8296.20). The highest costs were ward stay (£3994.00, IQR £1,765.00-£7,013.00), theatre utilisation (£2962.00, IQR £0.00-£4,286.00) and overheads (£1705.10, IQR £896.70-£2432.20). Cost (£17,455.00 [IQR, £13,194.00-£23,308.00] versus £7697.00 [IQR £3871.00-£10,847.00], p<0.001) and loss (£4890.00 [IQR £1308.00-£10,009.00] versus £1882.00 [IQR £313.00-£3851.00], p = 0.02) were greater in the operative versus the nonoperative group. There was no difference in cost (£17,634.00 [IQR £12,965.00-£22,958.00] versus £17,399.00 [IQR £13,394.00-£23,404.00], p = 0.98) or loss (£5374.00 [IQR £1950.00-£10,143.00] versus £3860.00 [IQR -£95.50-£7601.00], p = 0.21) between the open reduction and internal fixation (ORIF) and revision groups. More patients required blood transfusion in the operative versus the nonoperative group (17 [17.9%] versus 0 [0.0%], p = 0.009). There was no difference in any clinical outcome between the ORIF and revision groups (p>0.05). CONCLUSION PFF treatment costs are high with inadequate reimbursement from NHS tariff. Work is needed to address this disparity and reduce hospital costs. Cost should not be used to decide between ORIF and revision surgery.

Abstract
Abstract
Background
Intracerebroventricular streptozotocin (ICV-STZ) injection is among the best animal models to simulate sporadic Alzheimer’s disease (sAD). Abnormality in brain insulin signalling, neurodegeneration, neuroinflammation, cholinergic damage, mitochondrial dysfunction, genetic abnormality, respiratory problem, oxidative stress, gliosis, sleep disturbances are associated with cognitive abnormalities seen in ICV-STZ injected rats. Available experimental evidence has used varying doses of STZ (<1 to 3mg/kg) and studied its effect for different study durations, ranging from 14-21 (short), 30-42 (mild), 90-105 (moderate) and 250-270 (long) days. These studies indicated that 3mg/kg of body-weight is the optimum dose for inducing sAD in the rodents. However, studies on the pathological process with related the morphological and functional abnormalities reported were illusive.
Objective/Method
Hence in the present study, we have investigated the morpho-functional changes after 3mg/kg ICV-STZ treatment with a follow-up of two months in 54 male Wistar rats (ethical no. 937/IAEC/PhD-2016).
Results
Exhibited a spatial, episodic and avoidance memory decline and increase in anxiety (p<0.05) in ICV-STZ group progressively with time from 15th day to 60th day post-injection. Morphometry showed hippocampal atrophy with CA1, CA3 layer thinning (p ≤0.01) and loss of neurons (p<0.0001) associated with third ventricular enlargement (p= 0.007) in ICV-STZ rats versus sham, along-with extracellular amyloid plaque in AD rats with Congored staining. In addition, spine morphometry with Golgi-Cox impregnation of mossy fibre showed a reduction of spine density in AD group versus control and sham group (p<0.0001). Finally, immunohistochemistry of GSK3ß, PI3K and mtCOX-1 antigen in coronal sections revealed an increase in mean intensity of GSK3ß and decrease in PI3K and mtCox-1 in brain areas associated with limbic system in ICV-STZ group on 60th day.
Conclusion
These findings suggest progressive dementia and anxiety in 3mg/kg STZ treated rats, which may be due to hippocampal atrophy, amyloidopathy, ventricular enlargement, synaptic dysfunction and deficits in energy homeostasis of brain.

Abstract
Background
Intracerebroventricular streptozotocin injection at 3mg/kg of b/w causes phenotypes similar to that of sporadic Alzheimer’s disease (sAD) from 14th day post-injection. On the other hand, the body of evidence indicated that impairment in the sAD is the major contributor for cognitive decline. Taken together, we tested the adult neurogenesis hypothesis in streptozotocin model of sAD in female Wistar rats after extremely low magnetic stimulation (MF: 17.96, 50Hz, 2hr/day, 21days).
Method
33 rats were randomly divided into three groups viz. Sham+MF, AD and AD+MF. Consequently, animals were first induced AD with stereotaxic manipulation and then they were exposed to low frequency magnetic field stimulation, followed by terminal cognitive behavioural tasks brain tissue being isolated for both biochemical and subcellular expression experiments (ethical no. 12/IAEC-1/2017).
Results
Showed reduction in latency to the goal quadrant (p= 0.002) and transfer latency (p= 0.045) in AD+MF group versus AD. Even, Dirichlet distribution of time spent in 4 quadrants indicated un-uniform in all the groups except AD group (p= 0.067, LRS= 7.35). Further, cell count in CA3 and DG exhibited increase in cell density in AD+MF group (p<0.05). However, we found significant reduction in SOD1 activity after MF treatment (p= 0.035) but no change in GSH level in hippocampus and frontal cortex. Interestingly, these changes in AD+MF animals are associated with increase in density of BrdU+/Nestin+ cells in granular layer (p= 0.002) and hilus region (p= 0.0005) of DG along with increase in expression of L-type Ca2+ channels as compared to AD group.
Conclusion
This experimental evidence suggests that non-invasive brain stimulation can promote adult neurogenesis by activating L-type ca2+ channels in the hilus, which intern helps in retention of long-term memory even after sAD.

Abstract
The prevalence of cognitive decline and dementia is increasing in older adults, their prognosis is poor. Multiple emerging evidence shows that early intervention can delay and /or prevent their progression, however, early-detection markers are invasive, expensive, and not easy to routinely measure. Saliva can be an attractive source of early cognitive decline markers because oral health is linked with cognitive function and oral fluids are connected with brain fluids, and abnormal brain protein markers can leak out to saliva and vice-versa. Using global unbiased LC-MS/MS-based proteomics of 22 saliva samples of cognitively impaired and 39 cognitively healthy older adults (>60 years old) from large, multi-site study called Microbiome in aging Gut and Brain (MiaGB) consortium, revealed that 22 proteins were uniquely for cognitively impaired group while 44 were unique for cognitively healthy controls. In addition, among 78 differentially abundant proteins between cognitively impaired and control groups, half (39) were upregulated, and half (39) were downregulated. Notably, unique proteins in saliva of participants with cognitive impairment were from neurological pathways like NGF signaling, mTOR signaling and LPS-stimulated MAPK signaling. In addition, differentially abundant proteins in participants with cognitive impairment enriched with glucocorticoid receptor signaling, LXR/RXR activation, and L-DOPA degradation-pathways, while they were deficient of pathways like complement C3 and lysozyme pathways. We discovered that the novel saliva proteins and their pathways could blindly differentiate cognitive impaired from healthy older adults. These data suggest that we discovered novel saliva-based proteins that can be used as biomarker to predict/diagnose cognitive-impairment in older adults.

Abstract
The prevalence of age-related cognitive disorders is increasing. Effective prevention and treatment interventions are unavailable due to a poor understanding of aging biology. Multiple emerging evidence indicates that the gut microbiome is linked with age-related disorders; however, their clinical importance in differentiating and predicting the risk of cognitive decline or dementia is largely elusive. Utilizing samples and data of a large, multi-site clinical study across the state of Florida called Microbiome in aging Gut and Brain (MiaGB) Consortium, our whole genome microbiome sequencing revealed that the viral and archaeal population was significantly reduced in the gut of older adults with dementia (n=8) compared to those with mild cognitive impairment (MCI) (n=25) and normal cognition (n=59). Whereas the fungi were exclusively detected in the controls only. Alpha diversity of the participants with MCI and dementia was lower than the cognitively healthy controls. The abundance of Actinobacteria and Verrucomicrobia phyla was higher, and Firmicutes phylum was lower in the participants with dementia. Bacteriophages Lactobacillus prophage Lj771 and Microbacterium phage Min1 were exclusively detected in the gut of the participants with dementia. The study also identifies key metabolic pathways altered in the controls versus the cognitive impairment state. Our biomarker discovery analyses also revealed that these unique microbiome signatures and pathways might have predictive power for cognitive decline and dementia risk and offer new targets for future therapeutic interventions.

Abstract
To evaluate and compare pre and post treatment results using the following parameters by (a) Dual probe pH monitoring. (b) Laryngeal mucosal changes as assessed by direct video laryngoscopy/stroboscopy using Belafsky scores. (c) Voice changes by using GRBAS and Dr Speech software for speech analysis. In our study we have evaluated and compared voice and laryngeal changes in patients with dysphonia and RSI > 10 (which is suggestive of LPR) before treatment and after 6 months of treatment with Tab. Pantoprazole and Tab. Mosapride. This prospective study was carried out on 50 patients attending the ENT OPD of a tertiary care referral centre over a period of 18 months i.e. from Nov 2008 to Apr 2010. The study showed that prolonged therapy (> 6 months) is required to treat LPR effectively and 24 h ambulatory dual probe pH metry and videolaryngoscopy to assess RFS are the most preferred diagnostic tools in LPR. Dr Speech software for voice analysis can give an objective assessment of voice changes in LPR before and after treatment. The treatment consisting of PPI and prokinetic drugs proved to be effective in laryngopharyngeal reflux disease as improvement was seen in all the parameters including reflux findings score, subjective and objective voice assessment. According to results of our study, 24 h ambulatory dual probe pH metry, Reflux Finding Score (RFS), subjective and objective acoustic parameters can be used as indicators of efficacy of treatment.

Abstract
Dog bites injuries are a significant cause of morbidity and mortality. Conventionally, it was suggested to leave the wounds open due to probable increased risk of infections and occurrence of rabies with suturing.Recent publications indicate that primary closure does not necessarily affect the chances of infection but definitely helps in improving the quality of scar. We are presenting our experience and protocol for primary closure of all dog bite wounds. From March 2020 to February 2021, 10 consecutive patients of all ages coming to the emergency of our hospital with category 3 dog bite that penetrated the epidermis and dermis and presenting within 48 hours of injury were included. Every patient was administered first dose of anti rabies vaccine (ARV) (zero dose) for active immunisation and was also given injection tetanus intramuscularly. Mean age of patients in our study was 20.9 with range from 2 years to 90 years. Only 2/10 patients developed infections which were managed conservatively with drainage of abscess and antibiotics. Rest all patients recovered without complications. Primary closure of dog bite wounds when associated with debridement, sufficient irrigation, povidine iodine cleansing and antibiotic administration resulted in improved cosmetic appearance without increase in the rate of infection.

Abstract
Background and Aims The reliability of end tidal carbon dioxide (ETCO2) as a measure of arterial carbon dioxide (PaCO2) in pediatric laparoscopy is unclear. We evaluated the correlation of arterial to end tidal P(a-ET) CO2 during pediatric laparoscopy at two hours of pneumoperitoneum as the primary objective. We also compared P(a-ET) CO2 and alveolar to arterial oxygen gradient P(A-a) O2 and haemodynamics at fixed time points during surgery. Material and Methods A cross-sectional study was conducted in 25 children undergoing laparoscopic abdominal surgery. Arterial blood gases were drawn at T0, baseline, T10: ten minutes, T1h: 1 hour, T2h: 2 hours of pnuemoperitoneum and T 10d: 10 mins after deflation. The P(a-ET) CO2, P(A-a) O2, were measured from the blood gas and ETCO2 and FiO2 values on the monitor. The Pearson's correlation coefficient, the Wilcoxon rank test and Chi square test were used for statistical analysis. Results At T2h moderate correlation of P(a-ET) CO2 (r = 0.605, P = 0.001) with 40% children documenting accurate P(a-ET) CO2, -1 to +1 mm Hg was seen. Moderate correlation was also seen at T0, T10, T 10d but poor correlation at T 1h. The P(A-a) O2 increased progressively with surgery and did not correlate with P(a-ET) CO2. Heart rate was stable, but systolic blood pressures at T 10 and diastolic at T10, T 1h, T 2h were higher than baseline. Conclusion Moderate correlation was seen between PaCO2 and ETCO2 at 2 h of pnuemoperitoneum and at T0, T 10, and T 10d. P(A-a) O2 increased with surgery but did not correlate with P(a-ET) CO2.

Abstract
Deep neck space infection (DNI), is defined as infections in the deep fascia enclosing potential spaces of the neck. In the past the diagnosis and treatment of DNI have challenged. The health care personnel at all levels. The complex anatomy and the deep location of this region remains a big problem with significant risks of morbidity and mortality. The aim of this study is to analyse the difference in clinical presentation and microbiology of DNI in different age groups. Eighty two patients with DNI which were managed at the Department of Otorhinolaryngology, ABVIMS and Dr. Ram Manohar Lohia Hospital New Delhi, between November 2017 and March 2019 formed the basis of our prospective cross sectional observational study. We observed that DNI is a frequent and potentially life threatening condition in children and adults despite the use of antibiotics. For appropriate surgical management knowledge of complex spaces of the neck and their communication with the other spaces is necessary.

Abstract
Background and Aims There is interdependence between the upper and lower airway has led to the concept of a unified airway. Here we aim to study the impact of functional endoscopic sinus surgery (FESS) on the pulmonary function (PFT) of patients with chronic rhinosinusitis (CRS). Methods The proposed study is undertaken in the department of ENT, PGIMER & Dr. RML Hospital, New Delhi. It is a prospective study of 34 patients fulfilling the clinical criteria for (CRS) from the study period of Oct 2015 to Dec 2017 not responding to medical management and taken up for fess and follow up done with (PFT). Results The maximum incidence of cases was seen in the age group > 40 years. Chronic rhinosinusitis predominantly affected the male population. Nasal discharge was the commonest presenting complaint. A marked reduction is seen in the frequency of symptoms post-surgery. Conclusion CRS affected persons of adult age with maximum number in the age group of > 40 years, with a male:female ratio of approximately 2:1. Percentage improvement in FEV1 and FVC is more in age group > 40 years while percentage improvement in FEV1/FVC ratio is more in age group 31-40 years. Percentage increase in FEV1 and FVC is more in males while percentage increase in FEV1/FVC is more in females. Percentage increase in FEV1 and FVC is more in males and FEV1/FVC is more in females. Percentage increase in FEV1, FVC and FEV1/FVC ratio is more in cases of bilateral diseases then those with unilateral disease.

Abstract
To evaluate and compare expression of VEGF in patients of premalignant lesions and squamous cell carcinoma of oral cavity. The cross sectional observational study is undertaken at the department of otorhionolaryngology and pathology, PGIMER and Dr RML Hospital, New Delhi,from 1st Nov 2017 to 31st March 2019,with a sample size of 30 cases each of premalignant lesions and oral squamous cell carcinoma immunohistochemistry by polymer method. In the participants with oral SCC, VEGF expression of Score 1 was observed in verrucous and well differentiated tumor, Score 2 in moderately differentiated SCC & Score 3 in poorly differentiated SCC with a p value of 0.0001. The observed difference and value of proportion p, is statically significant. In this study we concluded that VEGF expression increases as the lesion progresses from premalignant lesions to oral squamous cell carcinoma and is strongly associated with lymph node status (N-staging). Thus, VEGF can be a target in chemotherapy and its therapeutic implications in the HNSCC needs further research. Levels of Evidence 1A: Systematic review of randomized control trials.
