Abstract
Rapid urban population growth, the urbanization of poverty, and the proliferation of slums are being driven to a great extent by this dynamic form of globalization. Consequently, the multifaceted effects of globalization on the poor and low-income populations in the cities need to be better understood in this context, both at the individual level and within the community. Therefore, the present study was conducted to highlight the various determinants affecting the lives and enhancing the vulnerability of the dwellers of four slum settlements present in various areas of Jammu City, India. Emphasis was made to integrate biological, physical, social, and spatial facets of vulnerability to understand the complex dynamics of urban areas in developing countries. A descriptive survey design was used for questions concerning the social and environmental aspects. Social aspects including age, sex, education, religion, caste, profession, and family income that correspond to social stratification acted as baseline information, while both indoor and outdoor environments such as housing conditions, sanitation, personal habits, solid waste disposal, disaster proneness, and air and water pollution problems were taken into consideration to assess the environmental aspect. Results indicated that the slum settlement has a migratory population with permanent or temporary settlements. The status of education and skill level is poor which results in poor economic development and social well-being of the dwellers in slums. The study also identified vulnerability of the population on social and environmental front which could result into severe health issues. The study concluded and recommended policy planning specified for slums for uplifting such unprivileged populations.

Abstract
The study was focused on evaluating the short-term irrigation effect of three different types of distillery wastewater, i.e., untreated, primary treated, and secondary treated, on the germination, growth, photosynthetic pigments, and antioxidant enzymes of pea (Pisum sativum L. var. Rachna). The findings indicated that exposure to 50% secondary treated distillery wastewater (ST50) resulted in the maximum values for positive germination parameters of pea, including germination percentage, germination value, germination index, peak value, vigor index, speed of germination, and tolerance index. The minimum values were observed at 100% concentration of untreated wastewater (UT100). In contrast, the maximum values for various negative germination parameters, i.e., percent inhibition, seedling mortality, and germination period, were observed at UT100 and minimum at ST50. All the growth parameters studied, i.e., length of shoot, length of root and length of seedlings, fresh weight of shoot, fresh weight of root, dry weight of shoot, and dry weight of root, showed maximum values at ST50 and minimum at UT100. Photosynthetic pigment analysis also followed a similar trend. The antioxidative enzyme characterization of Pisum sativum L. var. Rachna revealed the minimum values of catalase, ascorbic peroxidase, glutathione reductase, and superoxide dismutase at ST25 (25% concentration of secondary treated distillery wastewater) and maximum values were observed at UT100.

Abstract
INTRODUCTION Type 2 diabetes mellitus (T2DM) mainly results from the inability of muscle, fat, and liver cells to uptake glucose due to insulin resistance or deficiency of insulin production by the pancreas. Predisposition to T2DM may be due to environmental, hereditary, or both factors. Although there are many genes involved in causing T2DM, transcription factor 7-like-2 gene (TCF7L2) rs7903146 (C/T) single nucleotide polymorphism (SNP) found in genome-wide association studies (GWAS) is susceptible to T2DM. TCF7L2 is involved in pancreatic beta cell proliferation and differentiation via the Wnt signaling mechanism. OBJECTIVES To find the genetic association of TCF7L2 rs7903146 (C/T) gene polymorphism in patients with T2DM. METHODS A case-control study was conducted on 194 T2DM patients recruited from the endocrinology department at Indira Gandhi Institute of Medical Sciences, Patna, and 180 non-diabetic healthy controls that were age and sex-matched with the patients. All clinical examination and biochemical investigations like glycosylated hemoglobin (HbA1c), total cholesterol, triglycerides, high-density lipoprotein-cholesterol, and low-density lipoprotein-cholesterol; and determination of TCF7L2 gene polymorphism by allele-specific polymerase chain reaction (AS-PCR) were carried out for each subject. RESULTS The T allele of the rs7903146 (C/T) SNP was associated with a two-fold higher risk of T2DM and the heterozygous genotype (CT) with a 1.96 times higher risk. CONCLUSION There is a high association of this SNP with the development of T2DM in the eastern Indian population. Serial monitoring of HbA1c should be done in an individual having this type of polymorphism for early detection of T2DM to prevent future complications.

Abstract
BACKGROUND Hypothyroidism, characterized by insufficient thyroid hormone production, affects a significant global population, particularly women and the elderly. Recent research has emphasized the interaction between hypothyroidism and the hypothalamic-pituitary-adrenal (HPA) axis, highlighting cortisol's crucial role in the disease's physiological manifestations. OBJECTIVE This study aims to evaluate serum cortisol levels in hypothyroid patients, examining the intricate relationship between these two endocrine systems. By exploring the potential impact of altered cortisol levels on hypothyroidism's clinical presentation and progression, the study seeks to contribute valuable insights to enhance diagnostic approaches and develop more effective treatment strategies. METHODS A cross-sectional observational study was conducted at the Indira Gandhi Institute of Medical Sciences, assessing 65 hypothyroid cases and 65 age-matched euthyroid controls. Demographic data, medical history, and blood samples were collected, and serum cortisol, thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4) levels were measured. The study adhered to ethical considerations and received institutional approval. RESULTS The study included 65 hypothyroid cases (56 females, 9 males) and 65 euthyroid controls. Serum cortisol showed a significant correlation with TSH and T4 levels. Linear regression revealed a negative correlation between serum T4 and T3 levels and serum cortisol in hypothyroidism. A positive correlation was observed between TSH and cortisol. These findings align with previous studies, suggesting potential regulatory mechanisms and compensatory responses in hypothyroid patients. DISCUSSION The study's results emphasize the complex interaction between cortisol and thyroid function, suggesting a direct relationship between serum cortisol and TSH levels in hypothyroidism. Patients with severe hypothyroidism exhibited elevated cortisol concentrations, indicating a potential compensatory mechanism initiated by the HPA axis. Integrating serum cortisol assessment with conventional thyroid function tests could offer comprehensive insights into hypothyroidism severity and progression, providing a more holistic approach to patient care. CONCLUSIONS This study contributes to understanding the complex relationship between serum cortisol levels and hypothyroidism, emphasizing the need for further research to uncover underlying mechanisms and therapeutic implications. A comprehensive understanding holds the potential for more tailored and effective treatment strategies for individuals with hypothyroidism.

Abstract
Impact of pharmaceutical wastewater collected from aeration tank on aquatic macrophyte Spirodela polyrhiza (L.) Schleiden was studied in the present study. Various plant parameters such as chlorophyll, protein, and proline content of wastewater-exposed plants were examined to determine the toxic impacts of pharmaceutical wastewater. In addition to these parameters, electrolyte leakage (EL) and catalase (CAT) activities in S. polyrhiza were assessed for each day of exposure to the wastewater. S. polyrhiza was exposed to four different wastewater concentrations (25%, 50%, 75%, and 100%) under laboratory conditions for 7 days. The plants experienced severe toxicity as revealed by the reduction in photosynthetic pigments, increase in electrolyte leakage, and enhancement of antioxidant enzyme (CAT) activity in S. polyrhiza with an increase in concentration and time of exposure to pharmaceutical effluent.

Abstract
BACKGROUND Proper fixation of an epidural catheter is necessary for desired drug effect and to prevent catheter displacement. Different techniques have been used for epidural catheter fixation. The aim of the study was to compare the relative efficacy of Micropore™ surgical dressing, Tegaderm™, and Lockit plus® in preventing lumbar epidural catheter migration in children. METHODS We studied 167 patients aged 5-16 years, for up to 48 h. After the elective abdominal or lower limb surgery. Patients were randomly assigned to one of three groups: (1) Micropore™ surgical dressing (group M), (2) Tegaderm™ (group T), or (3) Lockit plus® (group L). Incidence and extent of epidural catheter migration in centimetres (cm); was compared at 24 and 48 h post epidural fixation. Correlation between epidural catheter migration and patient characteristics, and relative incidence of complications in three groups was also analysed. RESULTS Incidence of catheter migration was 9.6% at 24 h (group M: 7.1%, group T: 21.1% and group L: 0%) and 45.5% at 48 h (group M: 66.1%, group T: 45.6% and group L: 24.1%). After 48 h, absolute migration (mean migration rounded off to the nearest 0.5 cm) was least in patients in group L: 0.34 cm (1.39) compared to group M 1.22 cm (SD: 1.85) group T: 0.94 cm (1.94) (p = <0.001). CONCLUSION Up to 48 h after surgery, the Lockit plus® device demonstrated the less epidural catheter migration when compared to micropore surgical dressing or tegaderm in children undergoing elective abdominal or lower limb surgery.

Abstract
Introduction Metabolic syndrome is a group of aberrant metabolic indicators including hypertension, dyslipidemia, impaired fasting blood glucose, and obesity. It has been reported that thyroid hormones have a strong influence on the cardiovascular system, and hypothyroidism has been linked to metabolic syndrome components. The objective of the study was to find out the association of thyroid function with lipid profile in patients with metabolic syndrome. Methods A prospective cross-sectional study was conducted in an apparently healthy adult population visiting the outpatient Department of Indira Gandhi Institute of Medical Sciences (IGIMS), Patna, Bihar, India. Metabolic syndrome was diagnosed according to the International Diabetes Federation (IDF) criteria. Fasting blood glucose, triglyceride, and HDL levels were tested using the enzymatic photometric method. Thyroid-stimulating hormone (TSH), free T4, free T3, and insulin assays were performed using chemiluminescence immunoassay (CLIA). Results Out of 197 subjects recruited, 86 (51 males and 35 females) were diagnosed with metabolic syndrome according to the IDF criteria, and the rest 111 without metabolic syndrome were considered to be the controls. The mean age of subjects with and without metabolic syndrome was 45.8±8.5 and 46.4±9.6 years, respectively. The prevalence of thyroid dysfunction in the present study was 22%. In subjects with metabolic syndrome, most of the clinical and hormonal parameters (waist circumference, waist-height ratio, fasting blood sugar, fasting insulin, triglycerides, T3, and TSH) were significantly higher (p<0.001) as compared to those without metabolic syndrome. In case of lipid profile, the triglycerides in those with metabolic syndrome (262.8±112.3 mg/dL) were significantly higher (p<0.001) than those without metabolic syndrome (137.9±19.01 mg/dL), while the serum levels of HDL were significantly higher (p<0.001) in group without metabolic syndrome (50.5±3.9 mg/dL) as compared to those with metabolic syndrome (43.4±5.2 mg/dL). Also, the TSH levels were significantly higher (p<0.001) in subjects with metabolic syndrome (5.3±3.4 μl/mL) as compared to those without metabolic syndrome (2.6±1.4 μl/mL). Among all the components of metabolic syndrome, waist circumference and HDL showed a significant strong positive correlation (r=0.51) with TSH, and systolic blood pressure (r=0.39), diastolic blood pressure (r=0.39), and fasting blood sugar levels (r=0.44) showed significantly moderate positive correlation with TSH levels. T4 (OR=8.82; 95% CI: 1.56-49.8) and TSH (OR=1.61; 95% CI: 1.19-2.18) levels were observed to have significantly higher odds as risk factors for metabolic syndrome. Conclusion There is a significant association of thyroid function with lipid profile in metabolic syndrome. It was observed that along with metabolic alterations, cardiovascular symptoms of hypothyroidism and subclinical hypothyroidism are possible. Therefore, while evaluating people with metabolic syndrome, it may be appropriate to look into how well their thyroid glands are functioning.

Abstract
INTRODUCTION Breast cancer (BC), a heterogeneous disease, is one of the leading causes of cancer-related deaths among women worldwide. Circulating cell-free DNA (cfDNA) levels have been persistently reported to be elevated in BC patients. In the current study, we evaluated the correlation between the cfDNA levels in patients with BC and its subtypes. METHODS We recruited newly diagnosed, histopathologically confirmed BC patients aged >18 years (N=39), who did not have any previous malignancy, from the Department of Surgical Oncology, Indira Gandhi Institute of Medical Sciences (IGIMS), Patna, Bihar, India. A total of 6 ml of venous blood was collected from each subject; of this, 1 ml was subjected to complete blood count (CBC), and 4 ml was transferred to a clot-activated collection vial for plasma separation and the cfDNA isolation thereof. In addition to the basic demographic history of each patient, the information on the cancer subtype was as also recorded from the medical records of each patient. All the data were analysed by GraphPad Prism Version 8 (Insightful Science, LLC, San Diego, California, United States). One-way ANOVA was used to test the difference between more than two groups. Pearson correlation was also estimated between cfDNA levels and various CBC indices. A two-tailed p-value<0.05 was considered statistically significant. RESULTS The mean age of included patients was 48.6±8.20 years. The mean levels of cfDNA were 2.81±2.39 ng/µL. The mean counts of various blood cell types and other indices of CBC were in the normal range. Compared to BC patients with estrogen receptors (ER+), the cfDNA levels were significantly higher in patients with human epidermal growth factor receptor 2 (HER2+) and triple-negative BC (TNBC) (p<0.05). Conclusion: The elevated levels of cfDNA in patients with BC can be a prognostic marker for the disease subtype. However, more replicative studies are warranted to substantiate our findings.

Abstract
Background and aims A descriptive analysis of patients who underwent surgical debridement for coronavirus disease 2019 (COVID-19) related mucormycosis was described, which aimed at the evaluation of perioperative clinical characteristics, perioperative complications, and outcomes. Methods We conducted a retrospective study on patients who underwent surgical intervention for mucormycosis during the COVID-19 pandemic at a tertiary care institute in India from March 1, 2021, to June 30, 2021. The medical records of 92 patients were reviewed and analyzed. Results There was a male predominance with a mean age of 50.86 years. The most common comorbidity was diabetes mellitus (DM) (98.9%). Intra-operative complications included hypotension, hyperglycemia, and hypokalemia. Most of the patients (88%) were extubated inside the operation theater, and 48% of patients had mortality. Serum ferritin levels, computed tomography severity score (CTSS), and D-dimers were significantly high in the patient who had mortality. Conclusion The perioperative mortality in patients with COVID-19 associated mucormycosis was very high. DM was the most common comorbidity followed by hypertension. Pre-operative elevated serum ferritin, D-dimer, and high CTSS were associated with higher mortality; hypokalemia, followed by hypocalcemia, was the most common perioperative and post-operative electrolyte imbalance. Thorough pre-operative optimization, multidisciplinary involvement, and perioperative care are of the utmost importance to decrease mortality and improve outcomes.

Abstract
The present study was designed to test the hypothesis that poultry manure and biochar-amended soil alter the antioxidant enzyme activity of T. aestivum L. HD-2967. For this, a box experiment was conducted using poultry-amended soil (5 g and 10 g) irrigated with greywater (50% and 100%) which was analysed on 7 and 14 days of seed sowing. Antioxidant enzyme activity (catalase, ascorbate peroxidase, and guaiacol peroxidase ) was elucidated to be varied in response to soil biochar and manure amendments both for shoots and roots so as to counteract the reactive oxygen species generated by plants under stress. Also, it was observed to be decreased on a temporal basis. Moreover, soil-biochar amendments efficiently defend the irrigation stress, increase soil nutrition, and reduce waste quantity through sustainable reuse.

Abstract
Purpose The objective of the study was to compare the efficacy and safety of two concentration of autologous serum (AS) 20% vs 50% in recalcitrant moderate-to-severe dry eye patients. Methods A double-blind prospective, interventional, and randomized study was done on 44 patients (80 eyes) clinically diagnosed with moderate-to-severe dry eye disease (DED) that was refractory to conventional treatment, and all patients were treated with AS20% or AS50% for 12 weeks. We documented Ocular Surface Disease Index (OSDI), tear film breakup time (TBUT), OXFORD corneal staining score (OSS), and Schirmer test (ST) at baseline, 2,4,8, and 12 weeks. These parameters were compared in both groups and between the groups by using Student's t-test. The study included 11 males and 33 females. Results Out of 80 eyes, 33 eyes had moderate and 47 had severe DED. The age of patients in AS20% was 44.73 ± 14.37 years, and in AS50% was 46.41 ± 14.47 years. The most common etiology associated with DED was secondary Sjogren syndrome. In moderate DED, both the groups showed significant improvement in both subjective and objective parameters. But in severe DED, the AS20% group failed to show any significant improvement objectively, though subjective improvement was present. Conclusion In refractory severe DED patients, AS50% is better option for treatment and in moderate DED both concentrations of autologous serum are effective.

Abstract
ABSTRACTChemical fertilizers boost crop production; however, their continued use decreases soil fertility in the long run. Nutrient recycling by the beneficiation of poultry manure into biochar and application as a soil amendment is a long-term solution for plant nutrition. The effect of poultry manure, poultry biochar and crop irrigation with 50% and 100% greywater (GW) was assessed on soil properties and growth of wheat (Triticum aestivum L. HD-2967) on the 7th and 14th day of sowing. This resulted in greater nutrients (OC, OM, C:N have values of 3.51%, 6.58%, and 16.52, respectively) in soil on the 14th day after sowing irrigated with 100% GW for soil and 10 g biochar amendments than manure. The germination and growth were boosted to 100% on day 6 after seed sowing soil and 5 g biochar. The maximum number of leaflets (4), rootlets (7) and shoot length (26.58 cm) was obtained for soil and 10 g biochar amendments with 100% GW on the 14th day of sowing. The significance of the work is that greywater and poultry biochar has been used for the irrigation of wheat as a step towards the management of both solid and liquid waste. Biochar being a potential adsorbent reduces the pollutant load of greywater while increasing the nutritive value of soil substratum and influencing plant growth. The findings could offer crucial knowledge for creating agronomic procedures to repurpose the nutrients in poultry manure and biochar to grow crops by adding value to waste and meeting the goal of bioeconomic sustainability.

Abstract
The gut bacterial strains and their metabolites have been shown to play a significant role in obesity, but the molecular mechanisms underlying this association are largely unresolved. Obesity is a multifactorial problem and is controlled by various mechanisms and pathways to produce and store fat cells. Bacteriocins are secondary metabolites produced by gut bacteria to defend themselves against their competitors. Recently, they have gained great attention due to their role in metabolic disorders, including obesity. Stearoyl-CoA desaturase 1 (SCD1) is a key enzyme involved in the differentiation of adipocytes. The aim of this study is to show the regulation of SCD1 by bacteriocins and thus their importance in obesity control. We screened the human gut bacteriome for the presence of bacteriocins, predicted their structures, and showed their inhibitory role by molecular docking with SCD1. Further, to confirm the docking results, MDS of six top scoring SCD1-bacteriocin complexes were carried out for 100 ns. These six bacteriocins namely, Plantaricin S-beta, Carnolysin, Lactococcin B, Bacteriocin Iic, Plantaricin N, and Thermophilin A, with strong binding affinities, are primarily produced by bacterial strains from the Lactobacillaeacea family. These findings can be the basis of further experiments for enhanced understanding of the underlying mechanisms for obesity control, specifically bacteriocins driven regulation of the SCD1 enzyme. In addition, a consortium of bacterial strains producing these bacteriocins can be developed and used as probiotics for the amelioration of obesity and other metabolic complications.Communicated by Ramaswamy H.

Abstract
Background Lipase and amylase are the most frequently used biomarker for the diagnosis of pancreatic diseases, especially acute pancreatitis. Lipase has better diagnostic accuracy in comparison to amylase for the analysis of acute pancreatitis. However, lipase assay in random access analyzer is sometimes difficult to perform as it is exposed to different types of samples or reagents which may act as interference. Materials and Methods In our laboratory, we found the raised values (>500 IU/L) of lipase with normal amylase in some samples. However, the immediate rerun of these samples for lipase only showed normal (<80 IU/L) lipase level. To root out this fallacy, we performed reagent and sample carryover studies. Results The cause of the falsely raised value of lipase was revealed by reagent carryover studies. All samples which assayed triglyceride (TGL) followed by lipase immediately after it showed elevated (>500 IU/L) lipase value. This is due to the interference of microbial lipase used in TGL reagents. This was corrected by separating the analysis of lipase and TGL into two different instruments. Conclusion If interference testing is not done, the laboratories are prone to have an analytical error in reporting and hence lead to diagnostic error. Hence, after analyzer installation, interference testing should be included in the validation protocol.

Abstract
Introduction Single-nucleotide polymorphism (SNP) is a single-nucleotide change in a deoxyribose nucleic acid (DNA) sequence that occurs in >1% of population. Methylene tetra hydro folate reductase (MTHFR) C677T (rs1801133) and methionine synthase enzyme (MTR) A2756G (rs1805087) are two such SNPs occurring in coding sequence of the respective genes, which are frequently seen with neural tube defects (NTDs). MTHFR and MTR genes are involved in folate metabolism. The folate level in the course of pregnancy is treated as vital in the etiopathogenesis of NTDs. This study aims to explore the association of SNPs of both genes and red blood cell (RBC) folate levels in the predisposition to NTDs. Aims and Objective The purpose of this investigation was to determine the relationship of NTDs with polymorphisms in MTHFR and MTR genotype and to estimate and compare the RBC folate levels in NTD patients and controls. Materials and Methods A total of 397 individuals were enrolled (163 patients and 234 controls) for this observational study. Genotyping to find out MTHFR C677T and MTR A2756G was performed by polymerase chain reaction-restriction fragment length polymorphism technique from DNA extracted from the subject's blood. RBC folate level was estimated by chemiluminescence immunoassay method with the same blood sample. Results The total RBC folate levels were significantly less among cases compared to controls (P = 0.020). A significant difference for RBC folate was observed between case and control groups of various genotypes of MTHFR C677T, except heterozygote CT (P = 0.459). Among MTR A2756G, genotypes with only homozygous AA have significant difference (P = 0.003) for RBC folate levels. Among different types of NTDs, there were no significant differences for RBC folate levels. Among MTHFR C677T, T allele possessed 1.9 times risk compared to C allele for the occurrence of NTDs. In MTR A2756G polymorphism, the odds of developing NTDs were 1.6 times in heterozygous AG compared to homozygous AA. Similarly, the risk for NTDs was three times higher in subjects with both heterozygous AG and CT genotypes compared to wild-type homozygous AA and CC genotypes. Conclusion The total RBC folate levels were significantly less among cases compared to controls, and the genotypes had no such effect in decrease in RBC folate levels. The presence of mutant allele in homozygous or heterozygous condition for both SNPs had increased risk associated with NTDs.

Abstract
Titanium dioxide nanoparticles (TiO2NPs) usage is increasing in everyday consumer products, hence, assessing their toxic impacts on living organisms and environment is essential. Various studies have revealed the significant role of TiO2NPs physicochemical properties on their toxicity. However, TiO2NPs are still poorly characterized with respect to their physicochemical properties, and environmental factors influencing their toxicity are either ignored or are too complex to be assessed under laboratory conditions. The outcomes of these studies are diverse and inconsistent due to lack of standard protocols. TiO2NPs toxicity also differs for in vivo and in vitro systems, which must also be considered during standardization of protocols to maintain uniformity and reproducibility of results. This review critically evaluates impact of different physicochemical parameters of TiO2NPs and other experimental conditions, employed in different laboratories in determining their toxicity towards bacteria. These important observations may be helpful in evaluation of environmental risks posed by these nanoparticles and this can further assist regulatory bodies in policymaking.

Abstract
Antibiotics, the primary drugs used to cure bacterial diseases, are increasingly becoming ineffective due to the emergence of multiple drug resistance (MDR) leading to recurrence of previously sensitive pathogens. Human gut microbiome (GM), known to play an important role in various physiological processes, consists of pool of diverse microbes. Indiscriminate use of antibiotics during the life span of an individual may lead to development of resistant microbes e.g. Vibrio, Acinetobacter, Escherichia, Klebsiella, Clostridia, etc. in the human GM. Transmission of antibiotic resistant genes (ARGs) between pathogenic and commensal bacteria occurs more frequently in microbiome communities wherein bacteria communicate and exchange cellular constituents both among themselves and with the host. Additionally, co-factors like 'early vs. late' exposure, type of antibiotics and duration of treatment modulate the adverse effects of antibiotics on GM maturation. Furthermore, factors like mode of birth, ethnicity, malnutrition, demography, diet, lifestyle, etc., which influence GM composition, can also indirectly alter the host response to antibiotics. Currently, advanced 'omics' and culturomics approaches are revealing novel avenues to study the interplay between antibiotics and the microbiome and to identify resistant genes in these bacterial communities. Here, we discuss the recent developments that have given insights into the effects of antibiotics on the homeostatic balance of the gut microbiome and thus on human health.

Abstract
Objective The monocyte–macrophage system is central to the host’s innate immune defense and in resolving injury. It is reported to be dysfunctional in acute-on-chronic liver failure (ACLF). The disease-associated alterations in ACLF monocytes are not fully understood. We investigated the mechanism of monocytes’ functional exhaustion and the role of umbilical cord mesenchymal stem cells (ucMSCs) in re-energizing monocytes in ACLF. Design Monocytes were isolated from the peripheral blood of ACLF patients (n = 34) and matched healthy controls (n = 7) and patients with compensated cirrhosis (n = 7); phagocytic function, oxidative burst, and bioenergetics were analyzed. In the ACLF mouse model, ucMSCs were infused intravenously, and animals were sacrificed at 24 h and day 11 to assess changes in monocyte function, liver injury, and regeneration. Results Patients with ACLF (alcohol 64%) compared with healthy controls and those with compensated cirrhosis had an increased number of peripheral blood monocytes (p < 0.0001) which displayed significant defects in phagocytic (p < 0.0001) and oxidative burst capacity (p < 0.0001). ACLF patients also showed a significant increase in the number of liver macrophages as compared with healthy controls (p < 0.001). Bioenergetic analysis showed markedly reduced oxidative phosphorylation (p < 0.0001) and glycolysis (p < 0.001) in ACLF monocytes. Patients with monocytes having maximum mitochondrial respiration of <37.9 pmol/min [AUC = 0.822, hazard ratio (HR) = 4.5] and baseline glycolysis of ≤42.7 mpH/min (AUC = 0.901, HR = 9.1) showed increased 28-day mortality (p < 0.001). Co-culturing ACLF monocytes with ucMSC showed improved mitochondrial respiration (p < 0.01) and phagocytosis (p < 0.0001). Furthermore, ucMSC therapy increased monocyte energy (p < 0.01) and phagocytosis (p < 0.001), reduced hepatic injury, and enhanced hepatocyte regeneration in ACLF animals. Conclusion Bioenergetic failure drives the functional exhaustion of monocytes in ACLF. ucMSCs resuscitate monocyte energy and prevent its exhaustion. Restoring monocyte function can ameliorate hepatic injury and promote liver regeneration in the animal model of ACLF.

Abstract
Urine is a 'valuable waste' that can be exploited to generate bioelectricity and recover key nutrients for producing NPK-rich biofertilizers. In recent times, improved and innovative waste management technologies have emerged to manage the rapidly increasing environmental pollution and to accomplish the goal of sustainable development. Microbial fuel cells (MFCs) have attracted the attention of environmentalists worldwide to treat human urine and produce power through bioelectrochemical reactions in presence of electroactive bacteria growing on the anode. The bacteria break down the complex organic matter present in urine into simpler compounds and release the electrons which flow through an external circuit generating current at the cathode. Many other useful products are harvested at the end of the process. So, in this review, an attempt has been made to synthesize the information on MFCs fuelled with urine to generate bioelectricity and recover value-added resources (nutrients), and their modifications to enhance productivity. Moreover, configuration and mode of system operation, and factors enhancing the performance of MFCs have been also presented.

Abstract
OBJECTIVES Cellular and functional exhaustion of bone marrow mesenchymal stem cells (BM-MSC) is significantly associated with the loss of HSCs and hepatic osteodystrophy in cirrhosis. The molecular mechanisms underlying the dysfunction of BM-MSCs are not well understood. We investigated the underlying mechanisms of cellular and functional exhaustion of BM-MSCs in cirrhosis. METHODS The MSCs were isolated retrospectively from bone marrow of decompensated alcoholic cirrhosis patients {(Trial registration: ClinicalTrials.gov NCT01902511) (n=10; MELD=16.2±2.3; CTP=8.7±2.3)} and age and gender-matched healthy controls (n=8). Global gene expression profile of healthy bone marrow MSCs (hBM-MSCs) and cirrhosis patients BM-MSCs (cBM-MSCs) were done by mRNA sequencing. XFe24-bioanalyzer analyzed the bioenergetic potential of cells. Level of different cytokines and growth factors in BM-plasma and MSCs secretome were analyzed by Luminex-based bead array. RESULTS Analysis of differentially expressed genes showed significant (P<0.01) up-regulation of genes associated with ubiquitination and catabolism of proteins; TNF signaling, insulin resistance, and down-regulation of genes associated with DNA repair, protein processing, cell cycle, and mitochondrial respiration in cBM-MSCs in comparison to hBM-MSCs. Compared to hBM-MSCs, cBM-MSCs showed a significant defect in glycolysis due to insulin resistance and poor glucose uptake (P=0.002). This led to compromised self-renewal capacity and cellular loss of MSCs in cirrhosis. cBM-MSCs also showed a significant impairment in Oxidative phosphorylation (OXPHOS) due to mitochondrial dysfunction leading to defects in the osteogenic differentiation with early aging and senescence. CONCLUSION Compromised energy metabolism due to inflammatory and metabolic stress-induced insulin resistance underlies the cellular and functional exhaustion of BM-MSCs in cirrhosis.

Abstract
Objectives For Southern Asian countries like Pakistan, there is inadequate evidence of risk factors associated with mortality in patients suffering from acute coronary syndrome (ACS), especially non-ST elevation ACS (NSTE-ACS) cases. Therefore, aim of this study was to evaluate predictors of 6-months mortality of patients presenting with NSTE-ACS. Methods For this prospective observational study we recruited adult patients diagnosed with NSTE-ACS at a tertiary cardiac center. All he patients were followed-up after six months and survival status was recorded. Logistic regression analysis was performed for six-month mortality and odds ratio (OR) and 95% confidence interval (CI) were reported. Results Six-month follow-up was successful for 280 patients. On univariate analysis age >65 years, increased heart rate, cardiac arrest at presentation, Killip class II–IV at presentation, and diabetes were found to be associated with increased risk of 6-months mortality with OR [95% CI] of 4.27 [1.9–9.58], 1.25 [1.1–1.41], 139.44 [16.9–1150.78], 68.45 [7.88–594.41], and 2.35 [1.06–5.22] respectively. On multivariable analysis Killip class II–IV at presentation, thrombolysis in myocardial infarction (TIMI) score of >4, and global registry of acute coronary events (GRACE) score ≥150 were found to be independent predictors of mortality after six months of NSTE-ACS with adjusted OR of 32.93 [2.65–408.8], 3.42 [1.35–8.66], and 8.43 [3.33–21.38] respectively. Conclusions For patients with NSTE-ACS, our study showed seven clinical parameters to be associated with an increased risk of 6-month mortality. These included increasing age, increased heart rate, cardiac arrest at presentation, Killip class II–IV, diabetes, TIMI score of >4 and GRACE score of >150. Thereby aiding clinicians to apply strategic and precise interventions in monitoring these patients accordingly.

Abstract
Aflatoxin B1 (AFB1) is a most potent carcinogenic secondary metabolite produced by Aspergillus flavus. As a food safety concern, development of a rapid, cost effective, sensitive and easy to use method for the detection of aflatoxin is of prime requirement. In this study, AFB1 was conjugated with bovine serum albumin (BSA), and AFB1-BSA conjugate was purified by HPLC. Purification was confirmed by UV-Vis spectroscopy, FTIR and MALDI-TOF mass spectrometry. The polyclonal antibody was raised against AFB1-BSA conjugate in rabbit and purified by protein A sepharose and BSA sepharose affinity columns. Iron oxide nanoparticles (MNPs) were synthesised by co-precipitation method and their surface was functionalised with (3-aminopropyl) triethoxysilane (APTES). Size of APTES conjugated MNPs was determined by electron microscopy, and characterised by several biophysical techniques. The purified anti-AFB1 antibody was conjugated with surface functionalised MNPs and the conjugation was confirmed by determining the sizes of free and antibody conjugated MNPs by field emission scanning electron microscope where increase of particle sizes from 10-20 to 40-50 nm was observed due to antibody conjugation. Anti-AFB1 antibody conjugated MNPs were used for capturing AFB1 from the aflatoxin spiked wheat grains with a recovery percentage of more than 80% and used effectively five times. The captured AFB1 was then quantified by a sensitive colorimetric assay where colourless AFB1 was first converted into coumaric acid by NaOH. Subsequently, coumaric acid reacted with 2,6-dibromoquinone-4-chloroimide (DBQC) to a green-coloured indophenol product which was quantified spectrophotometrically. AFB1 contamination as low as 2 μg/kg in wheat grains was detected by the developed technique suggesting its potential application for both qualitative and quantitative analysis of aflatoxins present in feed and food materials.

Abstract
BACKGROUND AND AIMS Acute-on-chronic liver failure (ACLF) is a distinct clinical entity with high probability of organ failure and mortality. Since patients generally present late, experimental models are needed to understand the pathophysiology and natural course of the disease. METHODOLOGY To reproduce the syndrome of ACLF, chronic liver disease was induced in C57BL6 mice (6-8 weeks; approximately 20-24 g weight) by intraperitoneal administration of carbon tetrachloride (CCl4) for 10 weeks followed by an acute injury with acetaminophen (APAP) and lipopolysaccharide (LPS). Blood, ascitic fluid, and organs were collected to study cell death, regeneration, and fibrosis. RESULTS At 24 h post-APAP/LPS infusion, the liver tissue showed increased hepatocyte ballooning and endothelial cell TUNEL positivity. This was followed by progressive hepatocyte necrosis from perivascular region at day 7 to lobular region by day 11. ACLF (day 7 and day 11) animals showed increase in bilirubin (p < 0.05), prothrombin time (p < 0.0001), blood ammonia (p < 0.001), and portal pressure post-acute hepatocellular injury similar to human ACLF. Ascites was noticed by day 11 with median serum-ascites albumin gradient of 1.2 (1.1-1.3) g/dL. In comparison to cirrhosis, ACLF group (day 7 and day 11) showed significant decrease in Sirius red (p ≤ 0.0001), collagen1 (p < 0.0001), and a-SMA proportionate area (p < 0.0001) with loss of hepatocytes regeneration (p < 0.005). At day 11, ACLF animals also showed significant increase in serum creatinine (p < 0.05) and acute tubular necrosis suggestive of organ failure, compared to cirrhotic animals. CONCLUSION The CCL4/APAP/LPS (CALPS) model of ACLF mimics the clinical, biochemical, and histological features of ACLF with demonstrable progressive hepatocellular necrosis, liver failure, impaired regeneration, development of portal hypertension, and organ dysfunction in an animal with chronic liver disease.

Abstract
Anosmia with or without dysgeusia is frequently associated with Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) SARS-CoV-2 infection. SARS-CoV-2 virus affects the olfactory system and thus represents neurotropic and neuro-invasive nature of the virus. We found that tocilizumab’s role in reducing mortality in severe covid-19 infection is still questionable and aim of our study was correlation of anosmia and severity of covid-19 infection and requirement of tocilizumab in anosmia patients. To establish relationship between anosmia and severity of COVID-19 infection along with requirement of tocilizumab. This was a retrospective cum prospective cross sectional study done on COVID-19 patients who were admitted in normal COVID-19 ward and intensive care unit of Employee’s State Insurance Corporation Hospital, Udaipur and Maharaja Bhupal Hospital of Ravindra Nath Medical College between September 2020 and 15 January 2021 age group of 18 to 92 years, both sexes. We had asked about anosmia in all COVID-19 positive patients and followed all patients in perspective of severity of disease and tocilizumab. p value < 0.001 of prevalence of anosmia in COVID -19 patients who were isolated at home, admitted in ward and intensive care unit showed that anosmia is inversely related to severity of disease. Tocilizumab has no significant role in decreasing mortality in severe form of disease. Our study indicates that anosmia is related to the mildness of disease and there is no role of tocilizumab in decreasing the mortality in severe form of disease.

Abstract
Background The aim of this study was to determine the predictive value of the Global Registry of Acute Coronary Events (GRACE) score for predicting in-hospital and 6 months mortality after non-ST elevation acute coronary syndrome (NSTE-ACS). Results In this observational study, 300 patients with NSTE-ACS of age more than 30 years were included; 16 patients died during the hospital stay (5.3%). Of 284 patients at 6 months assessment, 10 patients died (3.5%), 240 survived (84.5%), and 34 were lost to follow-up (12%) respectively. In high risk category, 10.5% of the patients died within hospital stay and 11.8% died within 6 months (p = 0.001 and p = 0.013). In univariate analysis, gender, diabetes mellitus, family history, smoking, and GRACE score were significantly associated with in-hospital mortality whereas age, obesity, dyslipidemia, and GRACE were significantly associated with 6 months mortality. After adjustment, diabetes mellitus, family history, and GRACE score remained significantly associated with in-hospital mortality (p ≤ 0.05) and age remained significantly associated with 6 months mortality. Conclusion GRACE risk score has good predictive value for the prediction of in-hospital mortality and 6 months mortality among patients with NSTE-ACS.

Abstract
Introduction: Iron is an important factor in neural development. Iron Deficiency (ID) and Iron Deficiency Anaemia (IDA) anaemia is highly prevalent in patients of autism. There are a very small number of studies to show association between iron profile and autism. Aim: To investigate factors affecting iron status such as hemoglobin (%), serum iron, ferritin, and Total Iron Binding Capacity (TIBC) level in children with Autism Spectral Disorder (ASD) and healthy control. Materials and Methods: It was a case-control study done from April 2018 to April 2019. Total 100 participants were recruited of which 50 autistic patients were taken as cases, and 50 healthy subjects were taken as control. Childhood Autism Rating Scale (CARS) was used to evaluate the severity of autistic symptoms. Cut-off value of serum ferritin was <10 ng/mL for preschoolers (<6 years) and <12 ng/mL for school-aged (>6 years) children to evaluate ID. Anaemia was defined as haemoglobin <11.0 g/dL for preschoolers and <12.0 g/dL for school-aged categorical variables and were compared by using chi-square test. Normally distributed parametric variables were compared between groups by using independent samples t-test. Serum ferritin, iron, TIBC values were compared between severe, mild-moderate and control groups with ANOVA. The p-value <0.05 was accepted to be statistically significant. Results: Mean serum levels of ferritin iron TIBC were significantly reduced in ASD patients (p<0.001). The level of haemoglobin was also lower in ASD patients but it was not significant. Risk of ID and IDA was higher than normal subjects (RR for ID 1.74). Level of serum ferritin, iron and TIBC was lowest in severe autism as compared to mild-moderate autism and control groups. Conclusion: These findings suggest iron and ferritin levels should be measured in autistic patients as a baseline investigation and it may be used as a screening test for ASD.

Abstract
To explore the diagnostic value, pre-operative serum thymidine kinase 1(TK1), CEA, CA 19-9 and CA 72-4 levels were measured in 106 patients with colorectal carcinoma (53 colon and 53 rectal carcinoma patients) and 53 healthy controls. Sandwich Elisa, biotin-labeled antibody kit was used for TK1, and other tumor markers were measured using electro-chemiluminescence. Serum TK1 levels were significantly higher in CRC than in healthy controls (p<0.05) and showed significant associations with tumor stage, histopathological grade, lymph node status and metastasis (p<0.01). TK1 showed the highest (0.824-0.862) area under receiver operating characteristics curve (AUC) in comparison to other markers, and the AUC of the panel of combination tests performed even better (0.935-0.952). Significant variation was observed between the single biomarker test and their combination (Z test, p<0.01) and the Hosmer-Lemeshow test showed an adequate model of calibration. The algorithm based on combination of TK1, CEA, CA19-9 and CA72-4 can improve the diagnostic efficiency in CRC patients.

Abstract
Background Contrast-induced nephropathy (CIN) after primary percutaneous coronary intervention (PCI) is associated with increased mortality and morbidity. The aim of this study is to determine the frequency of CIN after primary PCI and its association with risk factors in patients with ST-segment elevation myocardial infarction (STEMI) at a tertiary care cardiac center in Pakistan. Methodology In this observational study, we included 282 patients who presented with STEMI and underwent primary PCI at the National Institute of Cardiovascular Disease, Karachi, Pakistan, from October 2017 to April 2018. The serum creatinine (mg/dL) levels were obtained at baseline and 48 to 72 hours after the primary PCI procedure, and patients with a 25% increase or ≥ 0.5 mg/dL rise in post-procedure creatinine level (after 48 to 72 hour) were categorized for CIN. Results Out of a total sample of 282 patients, 68.4% (193) were males, and the mean age was 56.4 ± 9.1 years. A majority of the patients, 78.7% (222), were hypertensive and 34% (96) were diabetic. The CIN was observed in 13.1% (37) of the patients, and increased risk of CIN was found to be associated with the presence of diabetes mellitus and increased (>200 mL) use of contrast during the procedure, with odds ratios of 2.3 (1.14-4.63) and 3.12 (1.36-7.17), respectively. Conclusions The CIN after PCI is a common complication associated with the presence of diabetes mellitus and the use of an increased amount of contrast during the procedure.

Abstract
OBJECTIVES Hyperglycemia is common in acute ischemic stroke patients and is associated with poor clinical outcome. However, aggressive reduction of post-stroke hyperglycemia did not improve clinical outcome, suggesting that other mechanisms are playing a detrimental role in hyperglycemic stroke. We hypothesize that the acute post-stroke immune response is altered in the hyperglycemic state leading to higher mortality and morbidity. The objective of this study was to characterize temporal changes in circulating immune cells after stroke and their association with clinical outcomes in hyperglycemic compared to euglycemic patients. PATIENTS AND METHODS This retrospective study included 97 (58 % euglycemic, 42 % hyperglycemic) patients presenting within 12 h of symptom onset of stroke. Blood neutrophil, monocyte and lymphocyte concentrations were measured sequentially for 96 h post stroke. Primary clinical outcome was the difference in the NIH stroke scale at admission compared to discharge. Secondary outcome measures included discharge disposition and the modified Rankin Scale (mRS) at 90 days. RESULTS Circulating neutrophils were significantly higher in hyperglycemic than in euglycemic patients within the first 48 h post stroke, while lymphocyte counts trended to be lower. Hyperglycemic patients had higher mortality rates, less favorable discharge disposition and worse neurological function at 90 days. In both groups, the neutrophil to lymphocytes ratio ((NLR) remained strongly associated with neurological function at discharge within the first 24 h (p < 0.001), and remained significant in hyperglycemic patients up to 48 h (p < 0.001). Multivariate regression analysis showed no confounding by other factors and a significant correlation with differences in NIHSS score (CI; - 9.287 to -1.46, p = 0.0077**) and NLR (CL; 0.6058-6.901, p = 0.0203*) in hyperglycemic patients. CONCLUSIONS Our data suggests that circulating immune cells play an important role in mediating poor clinical outcome in hyperglycemic patients following stroke. The NLR is a strong predictor of neurological outcomes in hyperglycemic patients. Thus, the modulation of immune cells may be a viable therapeutic approach to improve outcomes for this high risk group.

Abstract
Introduction: It was observed that approximately 10% of children with Nephrotic Syndrome (NS) are found as Steroid Resistant NS (SRNS). The data on the prevalence of non-autoimmune hypothyroidism among the SRNS in India is limited. Aim: To assess the prevalence of non-autoimmune hypothyroidism in the case of SRNS. Materials and Methods: A case control cross-sectional study was conducted in which 52 cases of SRNS and 52 healthy controls were enrolled. Thyroid profile like serum Thyroid Stimulating Hormone (TSH), Free Triiodothyronine (T3), Free Thyroxine (T4) done in the all cases and controls but anti-Thyroid Peroxidase (TPO), and anti-thyroglobulin antibody test was done in the case and control group with deranged thyroid function test. Low Free T4 (normal: 0.7-2 ng/mL) and elevated serum TSH above the upper limit of the reference range (>4.5 mIU/L) was defined as overt hypothyroidism, whereas elevation in serum TSH with a normal serum FT4 concentration was defined as sub clinical hypothyroidism. MedCalc statistical software Version 19.2.6 was used to do statistical analysis. Results: Prevalence of Non-autoimmune hypothyroidism was 38.46% (20 out of 52), 16 (30.76%) had subclinical and 4 (7.69%) had overt hypothyroidism in case of SRNS in comparison to 1.96% (1 out of 52) in control group. Out of 16 subclinical hypothyroid patients, two cases with grade 1, 12 cases with grade 2, and two cases with grade 3 found. Patients with SRNS had a mean (SD) TSH value of 4.5±4.7 mlU/L which was significantly higher than control (1.8±1.1 mlU/L). Serum levels of FT4 were within normal range. Anti-TPO and anti-thyroglobulin titre were in normal range in children with hypothyroidism. Conclusion: The prevalence of non-autoimmune hypothyroidism was high in cases of idiopathic SRNS. So, on the basis of this study estimation of thyroid profile in children with SRNS seems to be the rational approach which will lead to early diagnosis and timely management of hypothyroidism in SRNS.

Abstract
BACKGROUND AND AIM Acute hepatic insult triggers regeneration. If acute-on-chronic liver failure (ACLF) patients have a poorer regenerative response than acute liver failure (ALF) patients, and if so, the mechanisms underlying this, are not well understood. METHODS We investigated the status of hepatocyte proliferation, hepatic progenitor cell (HPC) mediated regeneration, non-parenchymal cells (through immunohistochemistery), cytokines and growth factors (cytokine bead array) in liver and peripheral blood of ACLF (n = 29) and ALF (n = 17) patients. Liver endothelial cells, mesenchymal cells and Kupffer cells were isolated from explant livers and analysis of regenerative factors was done by qRT-PCR. RESULTS Unlike ALF, the ACLF livers showed decreased hepatocyte proliferation (p < 0.001) and profound ductular-reaction with increased CK19 + hepatocytes (p < 0.0001). However, only decrease in Ki67+ hepatocytes was associated with 28 day mortality in ACLF (p < 0.001; HR = 0.78; 95% CI 0.69-0.88). In both groups, increase in plasma hepatocyte growth factor (HGF) (OR = 21.87 p = 0.002;), macrophage colony stimulating factor (MCSF) (OR = 21.73; p = 0.002) and stromal derived factor (SDF1)(OR = 10.2; p = 0.001) were associated with hepatocyte proliferation and decreased (> fivefolds) levels were associated with poor hepatocyte regeneration in ACLF patients. ACLF livers showed decrease in endothelial cells (p < 0.01) and expression of regenerative angiocrine factors C-X-C chemokine receptor type 7 (CXCR7), Inhibitor of DNA Binding 1(IDI) and HGF compared to ALF. In co-culture, while ALF liver mesenchymal stromal cells (LMSCs) induced the expression of CXCR7, IDI and HGF in human umbilical cord endothelial cells (HUVECs), the ACLF LMSCs were defective and showed decreased production of SDF-1, HGF and MCSF compared to ALF. CONCLUSIONS Decrease in hepatic endothelial cells and their regenerative angiocrine functions indicated by defective CXCR7-ID1 dependent HGF expression underlie the poor hepatocyte proliferation in ACLF compared to ALF patients. A robust hepatocyte self-replication is lacking in the livers of ACLF patients and is associated with poor survival.

Abstract
Several susceptibility genes have been associated with systemic lupus erythematosus (SLE) across different populations worldwide. However, data on association between genetic polymorphisms and SLE from Indian population is scarce. We aimed to replicate the association of single nucleotide polymorphisms (SNPs) in ITGAM, TNFSF4, TNFAIP3 and STAT4 genes with susceptibility to SLE in a North Indian population. Three hundred and ninety-four SLE patients and 583 unrelated healthy controls of the same ethnic background were enrolled. All samples were genotyped for SNPs in ITGAM (rs1143679), TNFSF4 (rs2205960), TNFAIP3 (rs5029939) and STAT4 (rs7574865) using TaqMan genotyping assay. At allele level, significant association with susceptibility to SLE was detected with polymorphisms in ITGAM (A vs. G, odds ratio (OR) = 1.73, 95% confidence interval (CI) = 1.30–2.30, p < 0.001), TNFSF4 (T vs. G, OR = 1.33, 95% CI = 1.08–1.64, p < 0.01), TNFAIP3 (G vs. C, OR = 1.91, 95% CI = 1.27–2.85, p < 0.01) and STAT4 (T vs. G, OR = 1.38, 95% CI = 1.13–1.69, p < 0.01). All four SNPs were associated with SLE under a dominant model with an OR of 1.47 (95% CI = 1.07–2.04, p < 0.05) for ITGAM, 1.30 (95% CI = 1.01–1.69, p < 0.05) for TNFSF4, 1.90 (95% CI = 1.25–2.90, p < 0.01) for TNFAIP3 and 1.38 (95% CI = 1.06–1.78, p < 0.05) for STAT4. Under a recessive model, significant association was found with ITGAM (OR = 4.87, 95% CI = 2.17–10.91, p < 0.001), TNFSF4 (OR = 1.84, 95% CI = 1.13–3.00, p < 0.05) and STAT4 (OR = 1.82, 95% CI = 1.19–2.77, p < 0.01). In conclusion, single nucleotide polymorphisms in ITGAM, TNFSF4, TNFAIP3 and STAT4 genes are associated with susceptibility to SLE in a North Indian population.

Abstract
INTRODUCTION Gossypiboma is a retained surgical sponge inside our body after surgical intervention. It is most commonly found in abdominal cavity. Its occurrence in thoracic cavity as intrapericardial gossypiboma is extremely rare. PRESENTATION OF CASE We present a 25 year old male with complaint of chest pain for 1 year. He had a history of total correction of Tetralogy of fallot 14 years back, at another hospital. On clinical examination and investigations including contrast enhanced computed tomography (CECT) of thorax; diagnosis of right anterior mediastinal mass of germ cell tumor was made and planned for thoracotomy. On exploration, the gauze piece of 31 cm was removed from the pericardial mass and a final diagnosis of gossypiboma was made. DISCUSSION Although gossypibomas are commonly reported in abdominal and pelvic surgery but a prolonged operative time, untrained staff, poor communication in sponge count may favour the occurrence in thoracic cavity. A patient with intrathoracic gossypiboma usually presents with chest pain, dyspnoea, thoracic mass or fever. CECT and Magnetic resonance Imaging (MRI) are useful imaging modality in such cases. Surgical exploration with histopathological examination confirms the diagnosis of gossypiboma. CONCLUSION In a postoperative patient who presents with chest pain and intrathoracic mass, gossypiboma should be a differential diagnosis even it is rare to occur in thorax.

Abstract
An interparietal inguinal hernia with undescended testis & obstructed external ring is a rare presentation. In Interperital hernia, the sac passes between the layers of the abdominal wall. Pre-operative diagnosis even with the help of USG & CT is really a challenging issue. Treatment is surgical exploration which also confirms the final diagnosis.
Introduction An interparietal inguinal hernia is a rare form of hernia. In this type of hernia, the sac passes between the layers of the abdominal wall of the inguinal canal area. Although its treatment is very simple but pre-operative diagnosis is really a challenging issue. Presentation of case A 62 years old male patient presented with complaint of a large swelling over right lower abdomen with absence of right testes since birth. The lump was measured 26 × 22 cm in size. Ultrasonography (USG) and Contrast enhanced computed Tomography (CECT) failed to diagnose as interparietal inguinal hernia which was proved intra-operatively. Few cases have been reported in the medical literature like this. Discussion Exploration revealed the large abdominal lump presenting as an interparietal inguinal hernia. Hernia sac was lying in between external & internal oblique muscles. The right testis was intraabdominal & atrophied. The external inguinal ring was almost completely obstructed. Conclusion An interparietal hernia with undescended testis is a very rare presentation. Even with USG & CT scan diagnosis is very challenging and final diagnosis can be made only intraoperatively.
