Abstract
OBJECTIVES To evaluate the risk of acquiring COVID-19 infection in patients who have undergone adeno-tonsillectomy (AT) as compared to their siblings. METHODS In this bidirectional cohort control study, 36 cohorts, younger than 18 y, who underwent AT, and 27 controls (siblings of the enrolled cohorts, younger than 18 y) were recruited. Incidence of COVID-19 was analyzed by symptoms suggestive of COVID-19 infection, COVID-19 testing, and SARS-CoV-2 specific antibody measurement. RESULTS In the cohort group, the overall COVID-19 positivity rate was 80.5% (n = 29/36) and symptomatic COVID-19 positivity rate was 68.9% (n = 20/29). Among the controls, the overall COVID-19 positivity rate was 44% (n = 12/27) and symptomatic COVID-19 positivity rate was 16% (n = 2/12). The cohorts had 1.8 times higher risk of contracting COVID-19 infection and the relative risk of symptomatic COVID-19 infections as compared to controls was 4.14. CONCLUSIONS This pilot study indicates that adeno-tonsillectomy poses children at a significantly higher risk of COVID-19 infections and likely other viral upper respiratory tract infections.

Abstract
BACKGROUND Delirium is a common complication in hospitalized older adults with multifactorial etiology and poor health outcomes. AIM To determine the frequency and predictors of delirium and its short-term and long-term outcomes in hospitalized older adults. METHODS A prospective observational study was performed in patients aged ≥60 years consecutively admitted to geriatric ward. Potential risk factors were assessed within 24 hours of hospital admission. Delirium screening was performed on admission and daily thereafter throughout the hospital stay using Confusion Assessment Method (CAM). Patients were followed up at 1-year post-discharge. RESULTS The study included 200 patients with mean age 73.1 ± 8.83 years. Incidence and prevalence rate of delirium were 5% and 20% respectively. Multivariable regression analysis revealed emergency admission (OR= 5.12 (1.94-13.57), p=0.001), functional dependency (Katz index of Independence in Activities of Daily Living (Katz-ADL) score <5) 2 weeks before admission (OR= 3.08 (1.30-7.33), p=0.011) and more psychopathological symptoms (higher Brief Psychiatric Rating Scale (BPRS) total score) (OR=1.12 (1.06-1.18), p=0.001) to be independently associated with delirium. Patients in delirium group had significantly high in-hospital mortality (OR= 5.02 (2.12-11.8), p=0.001) and post-discharge mortality (HR= 2.02 (1.13-3.61), p=0.017) and functional dependency (Katz-ADL score <5) (OR= 5.45 (1.49-19.31), p=0.01) at 1-year follow up. CONCLUSION Delirium is quite frequent in geriatric inpatients and is associated with high in-hospital and post-discharge mortality risk and long-term functional dependency. Emergency admission, pre-hospitalization functional dependency, and more general psychopathological symptoms are independently associated factors. Hence, earliest identification and treatment with early implementation of rehabilitation services is warranted.

Abstract
AIMS GDNF plays a crucial role in the stimulation of recovery, neuroplasticity and synaptic reorganization after spinal cord injury providing neuroprotection and neuroregeneration. Plasma GDNF levels are upregulated in cases of spina bifida owing to the intrauterine damage of the exposed spinal cord. Our aim was to compare the plasma GDNF levels in patients of spina bifida with non-spina bifida cases and assess the correlation with neurological impairment at one year of follow up. METHODS Single centre prospective analysis of cases of spina bifida from 2020 to 2022 at presentation and after one year of follow up post-surgery. Cases with hernia and hydrocele without any other disorders were recruited into the control group. Plasma GDNF levels were assessed with immunoassay kits and compared with neurological involvement. RESULTS 85 cases were included in the study. GDNF levels were elevated in cases compared to controls (mean 6.62 vs 1.76) with significant p value (<0.01). Same was observed for open and closed defects (mean 7.63 vs 4.86: p < 0.01). At follow up of 52 cases post-surgery cases with neurogenic bladder with abnormal urodynamic studies, sphincter involvement and motor impairment had significantly elevated baseline levels of GDNF compared with those who did not have this neurological impairment (p < 0.01). DISCUSSION The neurotrophic factor up-regulation can reflect an endogenous attempt at neuroprotection against the biochemical and molecular cascades triggered by the spinal cord damage. This upregulation can be represented as important biochemical markers of severe spinal cord damage and can be associated with severity of spine injury in MMC patients. Our results are in keeping with these findings, that, there were increased levels of plasma GDNF levels in cases of spinal dysraphism compared to control population. Also, the type of lesion reflecting the severity whether a closed or an open dysraphism, showed significant difference in levels between them suggesting, yet again, more damage in open defect as expected. The levels were higher with involvement of bladder, sphincter and lower limb power. CONCLUSION There is significant elevation of plasma GDNF levels in cases of spina bifida and this elevation is proportional to the degree of spinal damage and hence the neurological impairment. GDNF levels are a good predictor for assessing the severity of the lesion and thus the outcome in these cases. Additional prospective and long-term studies with a larger cohort are needed for a better understanding of neurotrophin pattern modulation in MMC.

Abstract
Introduction SuperAgers (SA) are older adults who exhibit cognitive capacities comparable to individuals who are three or more decades younger than them. The current study aimed to identify the characteristics of Indian SA by categorizing 55 older adults into SA and Typical Older Adults (TOA) and comparing their performance with a group of 50 younger participants (YP) (aged 25-50). Methods A total of 105 participants were recruited after obtaining informed written consent. The cognitive abilities of the participants were assessed using Wechsler Adult Intelligence Scale (WAIS)-IVINDIA, Color Trails Test, Boston Naming Test (BNT), and Rey Auditory Verbal Learning Test. Results SA outperformed TOA in all cognitive assessments (P < 0.001) and surpassed YP in BNT and WAIS-IV. SA's delayed recall scores were notably higher (12.29 ± 1.51) than TOA (6.32 ± 1.44). Conclusion SA excelled in all cognitive domains demonstrating resilience to age-related cognitive decline. This study highlights Indian SuperAgers' exceptional cognitive prowess.

Abstract
INTRODUCTION The dysregulated host immune response in sepsis is orchestrated by peripheral blood leukocytes. This study explored the associations of the peripheral blood leukocyte subpopulations with early clinical deterioration and mortality in sepsis. METHODS We performed a prospective observational single-center study enrolling adult subjects with sepsis within 48 h of hospital admission. Peripheral blood flow cytometry was performed for the patients at enrolment and after 5 days. The primary outcome was to explore the association between various leukocyte subpopulations at enrolment and early clinical deterioration [defined as an increase in the sequential organ failure assessment (SOFA) score between enrolment and day 5, or death before day 5]. Other pre-specified outcomes explored associations of leukocyte subpopulations at enrolment and on day 5 with in-hospital mortality. RESULTS A total of 100 patients, including 47 with septic shock were enrolled. The mean (SD) age of the patients was 53.99 (14.93) years. Among them, 26 patients had early clinical deterioration, whereas 41 died during hospitalization. There was no significant association between the leukocyte subpopulations at enrolment and early clinical deterioration on day 5. On multivariate logistic regression, a reduced percentage of CD8 + CD25+ T-cells at enrolment was associated with in-hospital mortality [odds ratio (OR), 0.82 (0.70-0.97); p-value = 0.02]. A reduced lymphocyte percentage on day 5 was associated with in-hospital mortality [OR, 0.28 (0.11-0.69); p-value = 0.01]. In a post-hoc analysis, patients with "very early" deterioration within 48 h had an increased granulocyte CD64 median fluorescent intensity (MFI) [OR, 1.07 (1.01-1.14); p-value = 0.02] and a reduced granulocyte CD16 MFI [OR, 0.97 (0.95-1.00); p-value = 0.04] at enrolment. CONCLUSIONS None of the leukocyte subpopulations showed an association with early clinical deterioration at day 5. Impaired lymphocyte activation and lymphocytopenia indicative of adaptive immune dysfunction may be associated with in-hospital mortality.

Abstract
OBJECTIVE The aim of this study was to look for feasibility of non-contrast CT (NCCT) in detecting peripheral zone prostate cancer (PCa). METHODS A retrospective analysis included 50 biopsy-proven PCa patients between April 2019 and March 2022 who underwent staging whole body prostate-specific membrane antigen (PSMA)/CT prior to treatment. The control subjects were 50 randomly selected adult male patients who underwent PET/CT for non-prostate malignancy during the same time period. Two readers independently calculated the Hounsfield unit (HU) of normal peripheral zone, central zone, and corresponding PSMA avid focus in cases. RESULTS No significant difference was seen in the mean HU value of normal peripheral zone between cases and controls. Significant difference in the mean HU was seen between the PSMA avid focus in cases (40.1 ± 6.2) and normal peripheral zone of cases (28.2 ± 7.0) and controls (27.7 ± 5.8). No significant difference was found between the mean HU values of high-grade PCa and non-high-grade PCa. Receiver operating characteristic (ROC) curve analysis revealed a mean HU cut-off of ≥35 for detecting PCa with a sensitivity and specificity of 86% and 90%, respectively, between cases and controls (AUC 0.88). CONCLUSION Detection of clinically significant PCa is possible on routinely performed NCCT scans. Radiologists should routinely look for and convey these findings to facilitate further work-up and early detection of PCa. ADVANCES IN KNOWLEDGE Our study adds to the knowledge that NCCT scans performed for unrelated indications can serve as a screening tool for clinically significant PCa.

Abstract
OBJECTIVES Sympathetic crashing acute pulmonary edema (SCAPE) is a subset of heart failure with a dramatic presentation. The unique physiology of this condition requires a different management strategy from the conventional practice. The trial objective was to compare the efficacy of high-dose and low-dose GTN in patients with SCAPE. METHODS This was an open-label randomised control trial conducted in a tertiary care teaching hospital in India from 11 November 2021 to 30 November 2022. Consenting participants were randomised to high-dose GTN or conventional low-dose GTN. The primary outcome was symptom resolution at 6 hours and 12 hours. Secondary outcomes included intubation rates, admission rates, length of hospital stay, and any short-term adverse effects of GTN and major adverse cardiac events (MACE) at 30 days. RESULTS Fifty-four participants were included (26 high-dose GTN, 26 low-dose GTN). At 6 hours, symptom resolution was seen in 17 patients (65.4%) in the 'high-dose' group, compared with 3 (11.5%) in the 'low-dose' group (p<0.001). At 12 hours, 88.5% of patients had a clinical resolution in the 'high-dose' arm versus 19.5% in 'low-dose' arm . The low-dose group had longer median hospital stay (12 hours vs 72 hours), more frequent MACE (3.8% vs 26.9%, p=0.02) and a higher intubation rate (3.8% vs 19.2%, p=0.08). The only short-term adverse effect seen was a headache in both the groups. CONCLUSION In SCAPE, patients receiving high-dose GTN (>100 mcg/min) had earlier symptom resolution compared with the conventional 'low dose' GTN without any significant adverse effects. TRIAL REGISTRATION Clinical trial registry of India (CTRI/2021/11/037902).

Abstract
BACKGROUND "Depth of invasion" is an additional index incorporated in 8th AJCC staging system for oral cavity squamous cell carcinoma based on its prognostic significance. Pre-operative assessment by clinical palpation and imaging modalities has been used with limitations. The aim of the study is to compare different techniques including clinical palpation, ultrasound, and magnetic resonance imaging with histopathology for assessment of depth of tumor invasion. MATERIALS Fifty patients of carcinoma tongue (T1-T3) were enrolled. Clinical palpation, Ultrasound tongue, and Magnetic resonance imaging were used to assess depth of tumor invasion. Microscopic depth of invasion was considered as reference. Statistical analysis was done to assess the level of agreement, reliability, and internal consistency. ROC analysis was done to find the "Area Under Curve" for microscopic depth versus ultrasound, MRI, and gross histopathological "depth of invasion". RESULTS Ultrasound tongue showed highest "area under curve", Intra class correlation (ICC:0.786) with a good consistency (Cronbach's Alpha:0.880) with histological reference compared to MRI(ICC:0.689;CA:0.816). Clinical palpation showed weak agreement (Kappa:0.43) for assessing depth. To observe the concordance between ultrasound and microscopic depth, Lin's Concordance Correlation Coefficient (CCC = 0.782) was calculated with 95% limits of agreement. Lin's concordance correlation between ultrasound and microscopic depth showed a good agreement. CONCLUSIONS Ultrasound tongue is a reliable imaging modality for pre-operative T staging by assessing tumor "depth of invasion" in carcinoma tongue patients with good internal consistency as per 8th AJCC staging system.

Abstract
Ammonia gas contributes to a number of environmental and human health concerns. The use of chalk, a cheap alkalinity source may reduce costs for biological systems. This research studies a closed liquid flow reactor to treat ammonia gas using chalk as biomass media and alkalinity source with high value calcium nitrate fertilizer production. The proposed reactor showed complete ammonia gas removal at high rate (500 mg N/L/day) and with low cost; where chalk dissolution and ammonia gas absorption contributed to alkalinity in the water for nitrification. High calcium ion concentration (up to 10,000 mg Ca2+ as CaCO3/L) showed only minor effects on ammonia absorption and nitrification rate.

Abstract
Introduction: Identification of occult lymph node metastasis is challenging in early tongue cancers. We conducted a prospective study to determine the most characteristics ultrasonic feature suggestive of metastatic node. Material and Methods: A preliminary study based on feasibility was planned on twenty five patients with squamous cell carcinoma of tongue (T1,T2) and N0 neck underwent ultrasonography of neck. The results of each ultrasonic parameters (size, shape, echogenicity, margin and hilum) for suspicion were analysed. Pathologic evaluation of surgical resected neck specimen served as the reference standard. Results: USG yielded sensitivity and specificity by size, by morphology, either size or morphology are 50.0% and 87.5%, 75.0% and 87.5, 75.0 and 83.3% respectively. Morphology alone has highest negative predictive value (NPV:91.3%) with accuracy of 84.3%. Conclusion: Morphology of the lymph node had highest sensitivity and specificity with highest negative predictive value correlating with its metastatic nature.

Abstract
Lung cancer is one of the common cancers globally with high mortality and poor prognosis. Most cases of lung cancer are diagnosed at an advanced stage due to limited diagnostic resources. Screening modalities, such as sputum cytology and annual chest radiographs, have not proved sensitive enough to impact mortality. In recent years, annual low-dose computed tomography has emerged as a potential screening tool for early lung cancer detection, but it may not be a feasible option for developing countries. In this context, exhaled breath condensate (EBC) analysis has been evaluated recently as a noninvasive tool for lung cancer diagnosis. The breath biomarkers also have the advantage of differentiating various types and stages of lung cancer. Recent studies have focused more on microRNAs (miRNAs) as they play a key role in tumourigenesis by regulating the cell cycle, metastasis and angiogenesis. In this review, we have consolidated the current published literature suggesting the utility of miRNAs in EBC for the detection of lung cancer.

Abstract
OBJECTIVES To prospectively assess the performance of pediatric appendicitis score (PAS) in diagnosing acute appendicitis in the children with lower abdominal pain and correlated with ultrasound findings; and to assess the impact of the PAS on clinical outcome and its efficacy in differentiating between complicated and uncomplicated appendicitis. METHODS A prospective study was done which included cases of lower abdominal pain. Appendectomy was done for PAS ≥ 6, and diagnosis was confirmed on histopathology. A receiver operator characteristic (ROC) curve was created to assess the PAS performance. The sensitivity, specificity, and accuracy of ultrasonography in diagnosing appendicitis were assessed, and analysis of agreement between ultrasonography and PAS score was done by kappa statistics. RESULTS Of 260 cases with lower abdominal pain, 205 were suspected of having appendicitis. One hundred fifty-nine had PAS ≥ 6. There were 2/159 (1.26%) cases of negative appendectomies and 2/46 (4.34%) cases of missed appendicitis. The mean PAS was significantly higher in patients with appendicitis than in those without appendicitis. The area under the ROC curve was 0.9925. Sensitivity, specificity, and positive and negative predictive value of PAS were 98.74%, 95.65%, 95.7% and 95.65%, respectively. Complicated appendicitis had significantly more PAS, fever, and cough tenderness than uncomplicated appendicitis. The sensitivity and specificity of ultrasonography were 86.79% and 17.39%, respectively. Agreement between ultrasonography-proven appendicitis and PAS-dependent appendicitis was weak. CONCLUSION PAS has high efficacy in diagnosing acute appendicitis. Clinical outcome was more favorable with the use of PAS. Ultrasonography should be used judiciously and in combination with clinical judgment.

Abstract
INTRODUCTION Radioisotope and blue dye are standard agents for performing sentinel lymph node (SLN) biopsy in breast cancer. The paucity of nuclear medicine facility poses logistic challenge. This study evaluated performance of radioisotope & methylene blue (MB) with indocyanine green (ICG) and MB for SLNB. PATIENTS AND METHODS This randomized controlled trial was conducted from December 2019 to July 2022 comparing SLN identification proportions of radioisotope-blue dye [Group A] with dual dye (MB + ICG; Group B]. Secondary objective included time required and cost effectiveness of performing SLNB. Sample size of 70 (35 in each arm) was calculated. Upfront operable node negative early breast cancer was included in the study. Clinico-demographic data, number & type of SLN, time taken were noted. Cost analysis was done including the equipment, manpower & consumables. Chi-square/Fisher exact test was used to compare proportion between two groups. p value of less than 0.05 was considered to represent statistical significance. RESULTS Seventy patients randomized to either group were similar in clinico-demographic and tumor characteristics. SLN identification rate (IR) was 91.43% in group A and 100% in group B. Overall IR of MB, radioisotope and ICG were 91.43%, 91.43% and 100%, respectively. Mean number of SLNs identified were 3 in group A and 4 in group B. Median time required for SLNB was 12 min and 14 min in either group, respectively. Cost of performing SLNB was higher in Group B. CONCLUSION SLNB using dual dye is non-inferior to radioisotope-blue dye in upfront operable early breast cancer. Trial registration number Clinical Trial registry India CTRI/2020/02/023503.

Abstract
This study aimed to explore the potential of Host-Guest coupling with Nanocarrier graphyne (GPH) to enhance the bioavailability of the drug 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (LUM) for brain tumor therapy. The electronic, geometric, and excited-state properties of GPH, LUM, and the graphyne@1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea-complex (GPH@LUM-complex) were studied using DFT B3LYP/6-31G** level of theory. The results showed that the GPH@LUM-complex was stable with negative adsorption energy (-0.20 eV), and there was good interaction between GPH and LUM in the solvent phase. The weak interaction forces between the two indicated an easy release of the drug at the target site. The Frontier Molecular Orbitals (FMO), Charge Density Analysis (CDA), and Natural Bond Orbital (NBO) analysis supported LUM to GPH charge transfer during complex formation, and the Reduced Density Gradient (RDG) isosurfaces identified steric effects and non-bonded interactions. UV-visible examination showed the potential of the GPH@LUM-complex as a drug carrier with a blue shift of 23 nm wavelength in the electronic spectra. The PET process analysis revealed a fluorescence-quenching process, facilitating systematic drug delivery. The study concluded that GPH had potential as a carrier for delivering LUM, and different 2D nanomaterials could be explored for drug delivery applications. The theoretical study's findings may motivate researchers to investigate the practical applications of GPH@LUM-complex in oncology.

Abstract
The computational simulations for electronic properties of cadmium (Cd) coordinated L-alanine NDI ligand (H2-l-ala NDI) based complex are the focus of this research. For the first time, the Cd-NDI complex (monomer) has been produced using water as the solvent; this is a new approach to synthesizing the Cd-NDI complex that has not been reported yet. Along with crystallography and Hirsch field analysis, CAM-B3LYP/LANL2DZ and B3LYP/LANL2MB basis sets were used, and in-depth characterisation of the Cd-NDI complex by following DFT and TD-DFT hypothetical simulations. Hyperpolarizabilities, frontier molecular orbitals (FMOs), the density of states (DOS), dipole moment (µ), electron density distribution map (EDDM), transition density matrix (TDM), molecular electrostatic potential (MEP), electron-hole analysis (EHA), and electrical conductivity (σ) have all been studied regarding the Cd-NDI complex. The vibrational frequencies and types of interaction are studied using infrared (IR) and non-covalent interaction (NCI) analysis with iso-surface. In comparison to the Cd-NDI complex with 2.61, 2.42 eV Eg (using CAM-B3LYP/LANL2DZ and B3LYP/LANL2MB basis sets, respectively) and 376 nm λmax, (in case of B3LYP/LANL2MB λmax is higher), H2-l-ala NDI have 3.387 eV Eg and 375 nm λmax, metal-ligand coordination in complex dramatically altered charge transfer properties, such as narrowing band gap (Eg). Based on the electronic properties analysis of Cd-NDI complex, it is predicted that the Cd-NDI complex will have a spectacular (nonlinear optical) NLO response. The Cd-NDI complex is discovered to be advantageous for the creation of future nanoscale devices due to the harmony between the Cd metal and H2-l-ala NDI, in addition to their influences on NLO characteristics.

Abstract
Lactococcus garvieae is a gram-positive cocci that has primarily been described as a pathogen in various fish species, but has increasingly been reported to cause endocarditis and other infections in humans [1]. Neonatal infection caused by Lactococcus garvieae has not been previously reported. Here we describe a premature neonate who developed a urinary tract infection with this organism and was successfully treated with vancomycin therapy.

Abstract
Around the globe, plastic has been entering the aquatic system and is ingested by organisms. Identification, optimal digestion method, and characterization of the polymers to trace sources are of growing importance. Hence, the present work investigated microplastics accumulation, digestion protocol efficiency, and characterization of polymers with FTIR analysis in the guts of five fishes (Lethrinus nebulosus, Rastrelliger kanagurta, Acanthopagrus arabicus, Otolithes ruber, and Euryglossa orientalis) from the Karachi coastal area, Arabian Sea. A total of 1154 microplastics (MPs) were ingested by 29 out of 33 fish species (87%). The highest average MP/fish was recorded in Otolithes ruber (54) and the lowest in Rastrelliger kanagurta (19.42). Microfibers were the most abundant shape with the highest numbers (35.52%) as compared to the rest of the MPs identified. Transparent microfibers were recorded as the highest in numbers followed by red, black, blue, and green. In this study, KOH with different concentrations and exposure times along with oxidizing agent hydrogen peroxide was tested (Protocols 3 and 4). Results showed these bases were highly efficient in obtaining optimal digestion of the samples. FTIR analysis confirmed that the majority of the polymers found in the fish guts were polyethylene and polypropylene. This study validated for the first time the presence of these polymers of plastic in marine fish from Pakistan.

Abstract
PURPOSE This phase II trial is designed to test whether the performance status (PS) of metastatic non-small cell lung cancer (mNSCLC) patients (pts) can improve with chemotherapy if their poor PS (Eastern Cooperative Oncology Group (ECOG) PS of ≥ 2) is due to disease burden rather than comorbidities. METHODS Age18-65 years, Charlson's comorbidity index < 9, serum albumin ≥ 3.5 g/dl, adequate bone marrow and organ function, & ECOG PS ≥ 2 as judged by the worst score of three independent physicians were administered 3 doses of weekly paclitaxel at 60 mg/m2/dose. The primary endpoint was an improvement in ECOG PS by 1 point at 4 weeks; others: toxicity (CTCAE v 5.0), quality of life (QoL) assessment at baseline and 4 weeks by EORTC QLQ-C30 and EORTC QLQ-LC13. Optimal Simon's 2-stage design was used. RESULTS Forty-six patients were included with a median age of 56 years (interquartile range, IQR 54-59), 12 (26%) had comorbid conditions, and 87% with ECOG PS 3/4. PS improved in 11 pts at 4 weeks and in 7 beyond this time point. Grade 3/4 toxicities are seen in 20% (most common: anemia and diarrhea). At a median follow-up of 4.8 m (95% CI 3.27-14.9), the median progression-free survival and overall survival were 3.3 months (95% CI 2.36-5.6) and 6.8 months (95% CI 2.47-8.8), respectively. QoL improved for global QoL, role functioning, pain, dyspnea, insomnia, pain in the chest, pain in other parts, and worsened for alopecia and sore mouth. CONCLUSIONS Abbreviated chemotherapy is a useful, well-tolerated strategy in carefully selected poor PS mNSCLC patients that can improve PS and QoL.

Abstract
Background Acute kidney injury (AKI) considerably increases the risk of short-term mortality in acute-on-chronic liver failure (ACLF) but predicting AKI is not possible with existing tools. Our study aimed at de novo discovery of AKI biomarkers in ACLF. Methods This observational study had two phases- (A) Discovery phase in which quantitative proteomics was carried-out with day-of-admission plasma from ACLF patients who initially had no-AKI but either progressed to AKI (n=10) or did not (n=9) within 7 days of admission and, (B) Validation phase in which selected biomarkers from the discovery phase were validated by ELISA in a larger set of ACLF plasma samples (n=93) followed by sub-group analyses. Results Plasma proteomics revealed 56 differentially expressed proteins in ACLF patients who progressed to AKI vs those who did not. The metallothionein protein-family was upregulated in patients who progressed to AKI and was validated by ELISA as significantly elevated in both- (i) ACLF-AKI vs no-AKI (p-value ≤ 0.0001) and (ii) progression to AKI vs no-progression to AKI (p-value ≤ 0.001). AUROC for AKI vs no-AKI was 0.786 (p-value ≤0.001) and for progression to AKI vs no-progression to AKI was 0.7888 (p-value ≤0.001). Kaplan-Meier analysis revealed that ACLF patients with plasma MT concentration >5.83 ng/mL had a high probability of developing AKI by day 7 (p-value ≤0.0001). High expression of metallothionein genes was found in post-mortem liver biopsies of ACLF patients. Conclusion Day-of-admission measurements of plasma metallothionein can act as predictive biomarkers of AKI in ACLF.

Abstract
Chronic inflammation in the gallbladder leading to persistent epithelium damage promotes invasive cancer. The study aimed to assess the prognostic value of PDL1 and CA19-9 markers in cancer/inflammatory lesions of the gallbladder. A total of 29 cases (19 cancer and 10 inflammatory) were included. The PDL1 protein concentration level and mRNA expression were assessed in the tissues' lysates by ELISA and real-time PCR, respectively. PDL1 and CA19-9 concentration levels were compared and statistically related with clinico-pathological variables. The PDL1 protein level and its relative mRNA expression were correlated. Kaplan-Meir survival and Cox regression analyses were conducted for predicting prognosis. This study investigated the PDL1 and CA19-9 marker expression in both cancer and inflammatory cases of the gallbladder (p = 0.48 and p = 0.17 respectively). PDL1 protein expression was significantly associated with the hormonal profile of the cases (p = 0.04) at an optimum cut-off value of 13 pg/mL, while the CA19-9 marker expression was correlated with the status of liver metastasis (p = 0.0043) and size of the tumor (p = 0.004). A low PDL1 concentration was found when compared to the CA19-9 level among cancer cases (p = 0.12) and proportional in the inflammatory lesions (p = 0.63). A significant positive correlation was found between the PDL1 protein and its relative mRNA expressions in the inflammatory lesions (p = 0.029) when compared to cancer cases (p = 0.069). Our results showed that a protein-based assay for PDL1 expression would be more sensitive compared to RNA based assays for GBC risk stratifications. Overall survival was predicted with CA19-9 and PDL1 levels (p = 0.0074, p = 0.23, respectively). PDL1 and CA19-9 may act as a probable predictor of a poor prognosis in gallbladder cancer (GBC) cases.

Abstract
Thirty puppies were randomly divided in to 3 groups for comparative evaluation of two commercial CPV vaccines. Each group was further subdivided in to < 6 months and < 3 months -old puppies and either vaccinated with a monovalent vaccine: Primodog, a combination vaccine: Duramune or maintained as a non-vaccinated control. Humoral immune response was determined by Hemagglutination Inhibition (HAI) on 21 and 35 -days after vaccination. The geometric mean titer (GMT) induced by Duramune, 21 and 35 -days post-vaccination was GMT 73.3 and 137.2, respectively. Comparatively, Primodog demonstrated higher GMT on 21 and 35 -days after vaccination: 97.0 and 168.9, respectively. The older puppies (< 6 months old) demonstrated higher seroconversion to both vaccines.

Abstract
Introduction Parkinson's disease (PD) is a neurological condition that impacts the physical and psychological functioning of the patients. The physical and cognitive changes come with social stigma and threats to roles previously associated with their identities. Objectives The current paper attempts to study the influence of the disease on the personal identity of the patients. Methods A systematic review was done on PD and personal identity following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. The Consolidated Criteria for Reporting Qualitative Research checklist was used to assess the quality of the papers. The selected papers were synthesized to understand the relationship between PD and personal identity. Results The emerging themes were: (1) dissociation of old personal identity: (1.1) Influence of physical symptoms, (1.2) influence of society and stigma, and (1.3) threats to roles associated with identity and (2) changing family dynamics. A Model of Personal, Family, and Disease Dynamics was also developed based on clinical first-hand experience with the patients and the review. Conclusion The personal identity of the PD patients shifts drastically as a result of their physical and psychosocial experiences. This also results in changed family dynamics, with the patient feeling sidelined due to loss of control and responsibilities in the family.

Abstract
Twenty-eight HLA alleles of the A and B loci were determined in 23 American Blacks and 50 Caucasians with primary ankylosing spondylitis (AS). The prevalence of HLA B27 was significantly increased in American Black patients (48 per cent) vs Black controls (two per cent), but was much less than the 94 per cent found in Caucasian patients (controls eight per cent). The lower prevalence of B27 in American Black patients vs Caucasian patients was significant (p < 0.001), and indicated that susceptibility to AS is not as closely associated with B27 in Blacks as in Caucasians. No other HLA antigen was significantly associated with AS in either racial group. Among B27 positive individuals, the relative risk of developing AS was significantly lower in American Blacks than in Caucasians. These data indicate that for diagnostic purposes, the absence of B27 is less important in ruling out AS in Blacks than in Caucasians.

Abstract
Obstructive uropathy in children is predominantly urinary system malformation and one of the leading causes of chronic renal failure. Antenatal ultrasound can detect obstructive uropathy in infants. It is important to conduct diagnostics not only to identify the obstruction level in urinary system, but to assess renal function, renal blood flow and urination. Children are given conservative and surgical treatment methods to restore urodynamics, prevent infectious complications, improve renal blood flow. Currently, there are no principles, approaches and technologies for medical rehabilitation of patients with obstructive uropathy, therefore, the use of selective chromotherapy, which has an activating effect on regional circulation, and sound stimulation improving muscles tone of pelvis and ureters, is pathogenetically reasonable and promising. OBJECTIVE To develop technologies of physiotherapy application (sound stimulation, selective chromotherapy) for inclusion in comprehensive medical rehabilitation of children with megaloureter. MATERIAL AND METHODS Clinical observations and special examinations have been performed in 90 children with megaloureter aged from 1 to 10 years. The patients were divided into 2 groups: 30 children (study group) received sound stimulation combined with selective chromotherapy; 30 children (the 1st comparison group) - sound stimulation; 30 children (the 2nd comparison group) - selective chromotherapy (blue spectrum). General clinical methods, ultrasound of kidneys and bladder with Doppler monitoring of intrarenal blood flow, functional methods of bladder examination were used. RESULTS The positive effects of separate and combined application of sound stimulation and selective chromotherapy on clinical and laboratory indicators, urodynamics of urinary tract and renal blood flow in children with megaloureter after surgery have been revealed. The efficacy of selective chromotherapy use in children with megaloureter and comorbid neurologic bladder dysfunction has been proven. CONCLUSION Modern technologies for the application of physiotherapy, namely selective chromotherapy and sound stimulation, to include them in the comprehensive medical rehabilitation of children with megaloureter, have been developed for the first time and their high efficacy has been proven.

Abstract
Pregnancy in women with systemic lupus erythematosus (SLE) is associated with an increased risk of adverse maternal and fetal outcomes. Risk is significantly increased when SLE pregnancy is complicated by anti-phospholipid syndrome (APS). Here, we present a case of a 21 year-old multi-gravid lady with SLE- associated APS who was diagnosed as such when she presented with multisystem flare at her 16 weeks of gestation. At presentation she had fever, multiple joint pain in both upper and lower limbs, loss of hair, history of recurrent oral ulcer, skin rash over hand and feet. Physical examination and laboratory evaluation were consistent with an active SLE flare. A diagnosis of antiphospholipid syndrome (APS) was made based on her clinical presentation and laboratory findings. The reported patient had APS secondary to SLE. She had all the risk factors that would confer a remarkably high risk of pregnancy morbidity: positive anti-SSA(RO) antibody and lupus anticoagulant, history of one neonatal death due to congenital heart block and two consecutive first trimester pregnancy loss. Multidisciplinary management approach with appropriate intervention and close monitoring can bring a successful outcome.

Abstract
INTRODUCTION Uterine cervical cancer (UCC) is the fourth most common health problem worldwide among women. Currently available biomarkers CA125, CA199, and CEA for diagnosis or prognostic evaluation of UCC have not got widespread acceptance. METHOD Whole blood samples of 64 patients with UCC were collected along with 63 healthy females and tested for serum levels of HE4 (sHE4). A cut-off value for positive result 64.0 pmol/L was set. Statistical analysis of different clinical variables was done. RESULT Serum level of HE4 has a significant role in the diagnosis of uterine cervical cancer. Its level increases with age, higher parity (P < 0.05), stage (P < 0.16), tumor size, and parametrial invasion. Negative result was seen with vaginal invasion, lymph node involvement & cases which had recurrence. Various histological types showed variable results. So the serum level of HE4 (sHE) level may play a role in the diagnosis & therapeutic monitoring of UCC. But the prognostic evaluation needs further studies. CONCLUSION sHE4 is useful in the diagnosis of cervical cancer, but its prognostic significance is under the question marks. It may be associated with higher values in higher stages. Higher parity of the patient is associated with higher level of HE4 in UCC.

OBJECTIVE Several interfascial interfacial plane blocks have been described in patients undergoing modified radical mastectomy. We conducted this study to evaluate the analgesic efficacy of ultrasound-guided serratus anterior plane block and erector spinae plane block in patients undergoing modified radical mastectomy. METHODS Totally, 80 female patients (18-70 years) undergoing modified radical mastectomy were randomised into 2 groups of 40 each and were given ultrasound-guided serratus anterior plane block or erector spinae plane block with 0.4 mL kg-1 of 0.375% ropivacaine in this prospective double-blind control trial. The groups were compared for the time to request of first dose of rescue analgesic, requirement of rescue analgesics, and patient satisfaction score. RESULTS The time to request of the first rescue analgesia was comparable in both groups (P =.056). Postoperative pain scores at rest at 0 minute were significantly lower in serratus anterior plane group as compared to erector spinae plane group (P =.03). The intraoperative fentanyl requirement and postoperative diclofenac and tramadol requirements were comparable between the 2 groups. The number of patients requiring rescue doses of fentanyl intraoperatively and rescue analgesics postoperatively was similar in both groups. The mean patient satisfaction score was also comparable in both groups. CONCLUSION Ultrasound-guided serratus anterior plane block and erector spinae plane block have comparable postoperative analgesic efficacy after modified radical mastectomy.

Abstract
Theileriosis is a hemoparasitic disease that affects a wide range of different animal species and is caused by various species of Theileria. This study aimed to determine the molecular epidemiology of Theileria annulata through microscopy and PCR, in crossbred cattle in some districts of Khyber Pakhtunkhwa, Pakistan. For this study, a total of 384 blood samples were collected from cattle in the Peshawar (n=120), Charsadda (n=94), Nowshera (n=84), and Swabi (n=86) districts. Microscopy and PCR were used to determine the overall prevalence of theileriosis, which was found to be 15.8 and 22.6%, respectively. Theileria annulata was detected in blood samples through PCR in the study area, and the target gene i.e., Tams 1, of positive samples was sequenced. The sequences in the current study revealed high sequence homology (ranging from 96 to 100%) with Tams 1 sequences of neighboring countries present in the NCBI database. Season, breed, age, and sex were found to be important risk factors among the several risk factors examined, whereas, among different clinical manifestations, lymphadenopathy showed a strong association with theileriosis. According to Cohen's kappa and ROC analysis, microscopy was proven to be a fair diagnostic test for detecting theileriosis in cattle, and may be used in combination with molecular techniques for screening a large number of animals.

Abstract
In recent years, the global Internet of Medical Things (IoMT) industry has evolved at a tremendous speed. Security and privacy are key concerns on the IoMT, owing to the huge scale and deployment of IoMT networks. Machine learning (ML) and blockchain (BC) technologies have significantly enhanced the capabilities and facilities of healthcare 5.0, spawning a new area known as "Smart Healthcare." By identifying concerns early, a smart healthcare system can help avoid long-term damage. This will enhance the quality of life for patients while reducing their stress and healthcare costs. The IoMT enables a range of functionalities in the field of information technology, one of which is smart and interactive health care. However, combining medical data into a single storage location to train a powerful machine learning model raises concerns about privacy, ownership, and compliance with greater concentration. Federated learning (FL) overcomes the preceding difficulties by utilizing a centralized aggregate server to disseminate a global learning model. Simultaneously, the local participant keeps control of patient information, assuring data confidentiality and security. This article conducts a comprehensive analysis of the findings on blockchain technology entangled with federated learning in healthcare. 5.0. The purpose of this study is to construct a secure health monitoring system in healthcare 5.0 by utilizing a blockchain technology and Intrusion Detection System (IDS) to detect any malicious activity in a healthcare network and enables physicians to monitor patients through medical sensors and take necessary measures periodically by predicting diseases. The proposed system demonstrates that the approach is optimized effectively for healthcare monitoring. In contrast, the proposed healthcare 5.0 system entangled with FL Approach achieves 93.22% accuracy for disease prediction, and the proposed RTS-DELM-based secure healthcare 5.0 system achieves 96.18% accuracy for the estimation of intrusion detection.

Abstract
T1 and T2 mapping techniques on cardiovascular magnetic resonance (CMR) provide insights into the myocardial tissue characterisation. We sought to establish the normal reference values of native T1 and T2 mapping in Indian population which can be used subsequently in clinical practice for addressing various cardiac pathologies. This prospective study included consecutive healthy volunteers (18-60 years) who underwent CMR on a 1.5 Tesla scanner using standard protocol. T1 mapping sequence was performed using MOLLI sequence with two different flip angles (FA) (35° and 50°). T2 mapping was performed using a hybrid gradient and spin-echo sequence sequence with two different FA (70° and 12°). Images were analysed with ROIs drawn in all the 16 AHA myocardial segments. 50 volunteers (average age-34 years, males-72%) were included. All the scans were normal. The mean T1 value at 35-degree FA was 946.86 + 14.16 ms and at 50-degree FA was 941.60 + 11.89 ms. The mean T2 mapping value at 70-degree FA was 45.67 + 1.39 ms and at 12-degree FA was 45.61 + 1.47 ms. The mapping values were not statistically different between males and females (all p > 0.2). The T1 and T2 mapping values did not show any significant correlation with LVEF, age, BMI or heart rate (all r < 0.33). The T1 mapping values significantly differ at 35- and 50-degree FAs (p = 0.002). The results establish the normal reference T1 and T2 mapping value for Indian population in institutes using the same protocol and parameters at 1.5 Tesla and may guide future research.

Abstract
Abstract
Background
Hip fracture is a common manifestation of osteoporosis. All patients who sustain a hip fracture should receive a specialist bone health assessment, including Serum Protein Electrophoresis (SPEP) because plasma cell disorders such as multiple myeloma are an important differential diagnosis. SPEP results can be challenging to interpret without training and expertise. We aimed to review the proportion of abnormal SPEP results in hip fracture patients and used a newly developed algorithm to assess urgency of referral to haematology.
Methods
The Orthogeriatrics and Haematology teams collaborated to develop an algorithm to help facilitate decision making in hip fracture patients with abnormal SPEP results. A retrospective study was then conducted using data from the local Hip Fracture Database from Quarters 1 and 3 in 2020, and the hospital electronic laboratory system. The algorithm was used to retrospectively determine which patients warranted haematology review. The electronic appointment system was then accessed to review whether those who warranted haematology referral had appointments on the system.
Results
Of 270 hip fracture presentations, 19 duplicate records were excluded. Five patients had no data and three patients had passed away. Of the remaining 243 patients, 193 (79.42%) had SPEP’s sent. Abnormalities were detected in 116 patients (47.74%). According to the SPEP referral pathway, two patients warranted routine referral and one patient required an urgent referral, none of whom appeared to have been referred to haematology. Two patients who did not warrant haematology referral were already under haematology for different conditions.
Conclusion
Not all patients who sustain acute osteoporotic fractures with an abnormal SPEP result require haematology referral. The need for an urgent or routine haematology can be guided by the SPEP result along with other clinical features. With the introduction of this pathway, it is proposed that all hip fracture patients will be triaged in a timely, appropriate, and consistent manner.

Abstract
BACKGROUND Multidrug-resistant TB (MDR-TB) treatment takes 18-24 months and is complex, costly and isolating. We provide trial evidence on the WHO Pakistan recommendation for community-based care rather than hospital-based care.METHODS Two-arm, parallel-group, superiority trial was conducted in three programmatic management of drug-resistant TB hospitals in Punjab and Sindh Provinces, Pakistan. We enrolled 425 patients with MDR-TB aged >15 years through block randomisation in community-based care (1-week hospitalisation) or hospital-based care (2 months hospitalisation). Primary outcome was treatment success.RESULTS Among 425 patients with MDR-TB, 217 were allocated to community-based care and 208 to hospital-based care. Baseline characteristics were similar between the community and hospitalised arms, as well as in selected sites. Treatment success was 74.2% (161/217) under community-based care and 67.8% (141/208) under hospital-based care, giving a covariate-adjusted risk difference (community vs. hospital model) of 0.06 (95% CI -0.02 to 0.15; P = 0.144).CONCLUSIONS We found no clear evidence that community-based care was more or less effective than hospital-based care model. Given the other substantial advantages of community-based care over hospital based (e.g., more patient-friendly and accessible, with lower treatment costs), this supports the adoption of the community-based care model, as recommended by the WHO.

Abstract
<b><i>Background:</i></b> Endobronchial administration of voriconazole is a potential therapeutic option for inoperable aspergilloma. <b><i>Objective:</i></b> This study aimed to assess the efficacy of endobronchial instillation of voriconazole for inoperable pulmonary aspergilloma. <b><i>Method:</i></b> Patients with mild to moderate hemoptysis, due to inoperable aspergilloma, were randomized to receive either medical therapy (MT) alone or bronchoscopic instillation of voriconazole with MT and followed up till 3 months. The primary objective of this study was to compare the percentage of patients achieving reduction in the severity of hemoptysis assessed on visual analogue scale (VAS) in intervention and control arm at 3 months. <b><i>Results:</i></b> This study included 60 patients (female = 47) with mean (SD) age of 40.6 (13.2) years who were randomized to receive either bronchoscopic instillation of voriconazole (<i>n</i> = 30) or MT alone (<i>n</i> = 30). At 3-month follow-up, the primary objective was achieved in 26/30 (86.7%) patients in intervention group as compared to 11/30 (36.7%) in the control group (<i>p</i> value <0.0001). The VAS score at 3 months was significantly lower in voriconazole group 13.9 (9.3) mm as compared to MT alone group 22.3 (11.5) mm, <i>p</i> value of 0.003. Bronchoscopic instillation of voriconazole was also associated with reduction in cough severity and size of the aspergilloma; however, there was no benefit of this therapy in terms of requirement of hospitalization and BAE. <b><i>Conclusions:</i></b> Our study shows that for nonoperable aspergilloma, bronchoscopic instillation of voriconazole is associated with reduction in the severity of hemoptysis. This therapy should be evaluated in large multi-center trials.

Abstract
Background: Cancellation of any scheduled surgery is a significant drain on health resources and potentially stressful for patients. It is frequent in menstruating women who are scheduled to undergo open heart surgery (OHS), based on the widespread belief that it increases surgical and menstrual blood loss. Aims: The aim of this study was to evaluate blood loss in women undergoing OHS during menstruation. Settings and Design: A prospective, matched case-control study which included sixty women of reproductive age group undergoing OHS. Patients and Methods: The surgical blood loss was compared between women who were menstruating (group-M; n = 25) and their matched controls, i.e., women who were not menstruating (group-NM; n = 25) at the time of OHS. Of the women in group M, the menstrual blood loss during preoperative (subgroup-P) and perioperative period (subgroup-PO) was compared to determine the effect of OHS on menstrual blood loss. Results: The surgical blood loss was comparable among women in both groups irrespective of ongoing menstruation (gr-M = 245.6 ± 120.1 ml vs gr-NM = 243.6 ± 129.9 ml, P value = 0.83). The menstrual blood loss was comparable between preoperative and perioperative period in terms of total menstrual blood loss (gr-P = 36.8 ± 4.8 ml vs gr-PO = 37.7 ± 5.0 ml, P value = 0.08) and duration of menstruation (gr-P = 4.2 ± 0.6 days vs gr-PO = 4.4 ± 0.6 days, P value = 0.10). Conclusion: Neither the surgical blood loss nor the menstrual blood loss is increased in women undergoing OHS during menstruation.

Abstract
Mass testing for COVID-19 infection is one of the core measures in tackling the global spread of the disease. Testing is vital to diagnose and estimate cases, attack rates and case fatality rates- critical data for policy-making. As COVID-19 continues to spread globally, the demand for more extensive laboratory testing and innovative technology increases. However, countries around the world have been struggling to keep up pace with the worldwide demand to expand testing strategy. The pandemic evolves, so does our knowledge and understanding of diagnostic tests of COVID-19. Here we aim to review major challenges related to COVID-19 diagnostic tests and future development. So, the ongoing urgency and demand for tests would certainly steer the rapid uptake of novel techniques, which in turn would boost our understanding of diagnostic tests for COVID-19.

Abstract
Dendrobium nobile Lindl. is an orcid plant with important medicinal values. This is a colourful houseplant, and also a popular herb in traditional Chinese medicine (TCM). The variants of this plant from different geographic regions might be high, and in this study, we aimed to develop specific sequence characterized amplified region (SCAR) markers for the identification of specific variant of this plant. Different cultivars of D. nobile were collected from nine different places of China, and one cultivar from Myanmar. DNA materials were extracted from the plant samples, random amplified polymorphic DNA (RAPD) were developed, cloned and sequenced for the development of SCAR markers. We have developed four SCAR markers, which are specific to the cultivar from Luzhou China, and clearly distinguishable (genetically) from other cultivars. These SCAR markers are deposited in GenBank (accession number MZ417502, MZ484089, MZ417504 and MZ417505). Four SCAR markers for D. nobile are effective molecular technique to genetically identify the different cultivars or species, and this method is applicable for genetic characterization and identification of other plant species too.

Abstract
OBJECTIVE Our aim was to assess sexual activity, partner relationships among males who had been infected with COVID-19, to study the impact of COVID-19 infection on partner relationship and to find out the association between partner and sexual relationship during lockdown. MATERIALS AND METHODS A cross sectional study was conducted in Saudi Arabia through social media platforms via online questionnaire between December 1, 2020 and January 31, 2021 among 871 participants after a pilot study among 20 participants of which 497 were included in the study. Statistical analysis was conducted using SPSS version 20.0 (IBM Inc., Armonk, NY, USA). Responses were presented as frequencies and percentages and the association was studied using Chi squared test/Fisher's exact test. The value of p ≤ .05 was considered significant. RESULTS Out of the total study participants, nearly 85% of them belonged to the age range of 18 to 39 years, more than half of the participants were married. In the six months prior to the study being conducted, 268 respondents (53.9%) did not have sexual relationships. Respondents with positive COVID-19 infection reported that their partner lived with them in the same house during home isolation and was also found to be significantly associated with having intact sexual relationships in the last six months of the lockdown period (p-value < .001). Moreover, respondents who reported having good relationships with their partners during the pandemic were found to be significantly associated with having intact sexual relationships during the pandemic lockdown (p-value < .001). CONCLUSIONS Among the COVID-19-positive respondents, sexual activity and partner relationships were largely found to be intact during the pandemic lockdown period.

Abstract
Background:
Urinary tract infections (UTIs) are the most frequent bacterial infections, commonly seen in females. High degree of antimicrobial resistance in uropathogens has challenged the use of therapeutic agents. Fosfomycin which is an old antibiotic with distinctive characteristics, seems to be a promising novel therapeutic agent with a good bactericidal activity towards multi-drug resistant (MDR) uropathogens.
Objective:
The main objective of the study is to evaluate the antibacterial activity of fosfomycin among uropathogens causing cystitis.
Methods:
The study was carried out between 2017-2018. A total of 2060 UTI suspects from outpatient department (OPDs) and inpatient department (IPDs) were screened. Out of 2060 screened patients 1658 were IPD patients and 402 were OPD patients. Patient’s midstream urine samples were collected aseptically and processed according to standard protocols. The frequency of extended-spectrum-beta lactamases (ESBLs) producer and carbapenem resistance were estimated respectively. Cultures with significant growth of uropathogens were identified and minimum inhibitory concentration (MIC) to fosfomycin was determined by agar dilution (AD) and by E-test methods.
Results:
184 out of 2060 (8.9%) urine samples showed significant growth of uropathogens. Uropathogenic Escherichia coli (UPEC) (64%,118/184) was found to be the mostly isolated uropathogen. Among these Gram-negative uropathogens, 80% were ESBLs producers, 43.2% were carbapenem-resistant and 78% isolates were found to be MDR. The fosfomycin susceptibility for UPEC was 95% by AD method.
Conclusions:
This study suggests that Fosfomycin is reasonably effective and can be used in the treatment of MDR uropathogens along with uncomplicated UTIs.

Abstract
In the current study, the drug carrier efficiency of graphyne (GRP) for the transfer of the hesperetin (HPT) drug is evaluated for the first time. The GRP efficacy as a carrier is investigated using the density functional theory (DFT) technique to calculate various physiochemical characteristics such as dipole moment, bandgap, and chemical reactivity-descriptors for HPT, GRP and HPT@GRP complex. The non-covalent-interaction (NCI) plot indicated that GRP and HPT have weak interaction force, which is fundamental for the drug's noticeable offloading from the GRP carrier at its target location. According to frontier molecular orbital analysis, the highest occupied molecular orbital (HOMO) of HPT distributes the charge to the GRP, the lowest unoccupied molecular orbital (LUMO) during excitation. Charge transfer is further supported by charge-decomposition-analysis, which interprets the extensive overlap between HPT and GRP orbitals. In the case of the gas phase, the λmax of the HPT@GRP-complex is redshifted by 9 nm from GRP. In the solvent phase, the λmax value is also redshifted. These theoretically calculated spectra also match experimentally observed spectra rather well. The PET (photoinduced electron-transfer) method and electron–hole theory were used for the graphical explication of distinct excited states. The photoinduced electron transfer (PET) mechanism interprets fluorescence dimming because of interaction. Furthermore, GRP with cationic (+1) and anionic (−1) charge states (GRP+1/−1) showed minor structural disfigurement and formed stable HPT complexes. In the current study, HRP is loading and unloading on GRP very effectively, that can potentially be used in the oncology field. Due to this theoretical study, researchers will be interested in looking at other 2D nanomaterials for drug delivery applications. In the current study, the drug carrier efficiency of graphyne (GRP) for the transfer of the hesperetin (HPT) drug is evaluated for the first time.![]()

Abstract
OBJECTIVE To assess the role of shear wave elastography (SWE) in characterizing different endometrial and subendometrial pathologies. METHODS Seventy-three women with pathologically proven endometrial and subendometrial pathologies were enrolled in this prospective study and assessed with transvaginal SWE. The elasticity values (in kiloPascals), and the ratio of mean elasticity of the endometrial lesion to myometrial elasticity (E/M ratio) were compared in different pathologies. RESULTS There was a statistically significant difference (P <.001) in the mean, minimum, and maximum elasticity of the pathologies as well as the E/M ratio (P <.00001). In the analysis of the subgroups, the mean elasticity of endometrial polyp was statistically significantly lower than other subgroups (P <.01), while submucosal leiomyoma and focal adenomyoma had significantly higher values than other subgroups (P <.01). No statistically significant difference was noted in the mean elasticity of carcinoma and hyperplasia (P-.19). CONCLUSION SWE is a potential adjunct to ultrasound that provides an additional paradigm to characterize endometrial and subendometrial masses.
