Abstract
Tuberculosis (TB) is a chronic, life-threatening disease caused by unusual facultative intracellular bacteria, Mycobacterium tuberculosis. This bacterium has unique resistance to many antimicrobial agents and has become a major global health concern due to emerging multidrug-resistant strains. Additionally, it has developed multiple schemes to exploit host immune signaling and establish long-term survival within host tissues. Thus, understanding the pathways that govern the crosstalk between the bacterium and the immune system could provide a new avenue for therapeutic interventions. MicroRNAs (miRs) are short, noncoding, and regulator RNA molecules that control the expression of cellular genes by targeting their mRNAs post-transcriptionally. MiR-155 is one of the most crucial miR in shaping the host immune defenses against M. tuberculosis. MiR-155 is remarkably downregulated in patients with clear clinical TB symptoms in comparison with latently infected patients and/or healthy individuals, thereby implicating its role in controlling M. tuberculosis infection. However, functional probing of miR-155 suggests dual effects in regulating the host's innate defenses in response to mycobacterial infection. This review provides comprehensive knowledge and future perspectives regarding complex signaling pathways that mediated miR-155 expression during M. tuberculosis infections. Moreover, miR-155-targeting signaling orchestrates inflammatory mediators' production, apoptosis, and autophagy.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) is accountable for a plethora of infections, ranging from minor cutaneous manifestations to grave metastatic conditions. The dissemination of MRSA among cancer patients poses a substantial public health hazard on a global scale. This study explores the association between MRSA and bacteriophage-encoded immune evasion cluster (IEC) genes. This investigation employed a total of 168 pathogenic MRSA collected from 38 cancer and 130 non-cancer patients. A cefoxitin disc diffusion method followed by PCR analysis was used to identify the mecA gene. In this study, we employed singleplex and multiplexed PCR techniques to detect specific IEC genes. No association (p = 0.98) was observed between the sex and age of patients and MRSA isolates. However, MRSA isolates demonstrated a notable association (p = 0.01) with pus samples in non-cancer patients and skin swabs in cancer patients. The resistance profiles of MRSA strains from cancer and non-cancer patients did not show significant differences (p > 0.05). Notably, the sea gene was found to be more prevalent in MRSA isolates from cancer patients, displaying a significant association (p = 0.03). Additionally, this study identified two novel and distinct combinations of IEC types, namely V1 (sea, chp, scn) and V2 (sea, scn). Cancer patients had higher multidrug resistance and toxin gene abundance than non-cancer patients. The identification of two novel IEC patterns underscores the urgent need to control MRSA dissemination in hospitals and monitor emerging clones.

Abstract
Malaria caused by the Plasmodium falciparum strain is more severe because of this protozoan's ability to disrupt the physiology of host cells during the blood stages of development by initiating the production of the interleukin-10 (IL-10) family of cytokines. P. falciparum feeds on hemoglobin and causes host cells to adhere to the walls of blood vessels by remodeling their composition. IL-10 is produced by CD4+ T cells that inhibits antigen-presenting cells' activity to prevent inflammation. This cytokine and its family members are crucial in promoting malarial infection by inhibiting the host's protective immune response, thus initiating Plasmodium parasitemia. IL-10 is also responsible for preventing severe pathology during Plasmodium infection and initiates several signaling pathways to alter the physiology of host cells during malarial infection. This review summarizes the critical aspects of P. falciparum infection, including its role in signaling pathways for cytokine exudation, its effect on microRNA, the human immune response in malaria, and the role played by the liver hormone hepcidin. Moreover, future aspects of vaccine development and therapeutic strategies to combat P. falciparum infections are also discussed in detail.

Abstract
Applying a multistep approach, novel indolin-2-ones (IND) that possess an arylidene motif have been synthesized. Eight compounds were chosen for different biological tests (antimicrobial and cytotoxicity). IND containing 2-thienyl (4h) fragment have been found to exhibit good antimicrobial activity against B. cereus. Molecules that have 3-aminophenyl (4d) or 2-pyridyl (4g) groups have shown the best antifungal activities against all tested fungi. These compounds have also been noticed as promising pharmaceuticals against MCF-7 cancer cell lines. Experimental outcomes from the investigation of the interaction of 4d with DNA implied its moderate binding to DNA (KSV = 1.35 × 104 and 3.05 × 104 M-1 for EB and Hoechst binder, respectively). However, considerably stronger binding of 4d to BSA has been evidenced (Ka = 6.1 × 106 M-1). In summary, IND that contains m-aminobenzylidene fragment (4d) exhibits a good dual biological activity making it a promising candidate for further investigation in the drug discovery sector.

Abstract
Liver cirrhosis is a complication usually due to the consequence of persistent chronic liver disease. It is associated with different mechanisms, including hypoalbuminemia, impaired amino acid turnover, and micronutrient deficiencies. Consequently, cirrhotic patients can develop progressive complications like ascites, hepatic encephalopathy, and hepatocellular carcinoma. The liver is a vital organ that regulates the different metabolic pathways and transportation of trace elements. Zn is an indispensable micronutrient trace element involved in its crucial functions in cellular metabolic activity. Zn mediates its action by binding to a wide range of proteins; therefore, it imparts numerous biological effects, including cellular division, differentiation, and growth. It is also involved in critical processes for the biosynthesis of structural proteins and regulation of transcription factors and acts as a co-factor for the various enzymatic processes. As the liver is a significant regulator of Zn metabolism, its abnormalities lead to Zn deficiency, which has consequences on cellular, endocrine, immune, sensory, and skin dysfunctions. Conversely, Zn deficiency may modify the functions of hepatocytes and immune responses (acute phase protein production) in inflammatory liver diseases. This review has concisely stated the evolving indication of the critical role of Zn in biological processes and complications associated with liver cirrhosis pathogenesis due to Zn deficiency.

Abstract
The frequency of Staphylococcus aureus strains associated with oral cavity microbiota has prodigious consideration. Although S. aureus has been reflected as an ephemeral member of the human oral cavity microbiota, the isolation, identification, and characterization of S. aureus is important. The present study aimed to characterize S. aureus strains from the oral cavity microflora, isolation of S. aureus from the human oral cavity microbiota, and demographic information of the participants to evaluate exogenous factors associated with the presence of S. aureus and their genetic analysis linkage with different factors. The method used in this study is the isolation of oral cavity microbiomes using sheep blood agar and Mannitol salt agar. We performed antibiotic profiling with various antibiotics and genetic analysis utilizing gene-specific primers for specific genes, including nuc, mecA, pvl, agr, and coa. A significant number of S. aureus isolates were found in the oral cavity of humans 18/84 (21.42%), and all 18 strains tested positive for the confirmatory nuc gene. Antibiotic resistance-conferring gene mecA was positive in 10 (55.6%) isolates. It was found that the occurrence of pvl, agr, and coagulase (coa) genes was 9 (50%), 6 (33.33%), and 10 (55.6%), respectively. The genetic analysis reported that significant associations were present between male and mecA gene (P = 0.03) and coa (P = 0.03), smokers with the occurrence of mecA (P = 0.02), agr (P = 0.048) and coa (P = 0.02) genes. Likewise, the association of antibiotic usage was significantly found with mecA (P = 0.02), coa (P = 0.02); however, the individuals who have taken orthodontic treatment recently have a significant association with agr (P = 0.017). The use of mouth rinse was significantly associated with the prevalence of the pvl gene (P = 0.01), and tooth brushing frequency and inflammation of the buccal cavity were also statistically significant in relation to pvl gene prevalence (P = 0.02, 0.00, respectively). Moreover, calories and weight-controlled diet were significantly associated with mecA, agr, and highly significant with coa (P = 0.02, 0.048, 0.000), so all P < 0.05, and no significant association was found between the socioeconomic status of individuals with aforementioned analyzed genes.

Abstract
In the presented study, eight novel Meldrum's acid derivatives containing various vanillic groups were synthesized. Vanillidene Meldrum's acid compounds were tested against different cancer cell lines and microbes. Out of nine, three showed very good biological activity against E. coli, and HeLa and A549 cell lines. It is shown that the O-alkyl substituted derivatives possessed better antimicrobial and anticancer activities in comparison with the O-acyl ones. The decyl substituted molecule (3i) has the highest activity against E. coli (MIC = 12.4 μM) and cancer cell lines (HeLa, A549, and LS174 = 15.7, 21.8, and 30.5 μM, respectively). The selectivity index of 3i is 4.8 (HeLa). The molecular docking study indicates that compound 3i showed good binding affinity to DNA, E. coli Gyrase B, and topoisomerase II beta. The covalent docking showed that 3i was a Michael acceptor for the nucleophiles Lys and Ser. The best Eb was noted for the topoisomerase II beta-LYS482-3i cluster.

Abstract
The present study was conducted in order to determine the frequency of pvl gene among the pathogenic and healthy population isolates of Methicillin Resistant Staphylococcus aureus (MRSA) and Methicillin Sensitive Staphylococcus aureus (MSSA). For this purpose, nasal swab samples were collected from the healthy individuals (to be used as controls, all the samples were collected irrespective of the sex and age factors), the pathogenic samples were collected from different patients suffering from skin &soft tissue infections caused by S. aureus (to be used as test samples).Both of these population samples were analyzed for the presence of pvl gene. S.aureus were identified through conventional microbiological identification procedures. In the case of normal samples, 70 nasal swabs were collected and only 33 (47%) proved to be S. aureus while 20 pathogenic samples were collected and all (100%) were cleared as S. aureus. For further distribution of samples into MRSA and MSSA, antibiotic susceptibility pattern was checked by using the standard protocols of Kirby-Bauer disc diffusion method. Two antibiotic discs Oxacillin (OX: 1ug) and cefoxitin (FOX: 30ug) were used. Among healthy population, MRSA was found to be 79% (n=26) and MSSA were present as 21% (n= 7). Among pathogenic strains 100% MRSA was detected where n= 20. Detection of pvl gene among the MRSA and MSSA isolates was done by using the uniplex PCR followed by gel electrophoresis. MRSA and MSSA of normal healthy population carried 49% and 7% pvl gene respectively. While, pathogenic MRSA samples carried 46% pvl gene among them. Potentially alarming percentage of pvl gene is present among the normal healthy individuals which indicates a future threat and a major health concern.

BACKGROUND Extensively drug-resistant (XDR) Salmonella enterica serovar Typhi (S. Typhi) poses a grave threat to public health due to increased mortality and morbidity caused by typhoid fever. Honey is a promising antibacterial agent, and we aimed to determine the antibacterial activity of honey against XDR S. Typhi. METHODS We isolated 20 clinical isolates of XDR S. Typhi from pediatric septicemic patients and determined the minimum inhibitory concentrations (MICs) of different antibiotics against the pathogens using the VITEK 2 Compact system. Antimicrobial-resistant genes carried by the isolates were identified using PCR. The antibacterial efficacy of five Pakistani honeys was examined using agar well diffusion assay, and their MICs and minimum bactericidal concentrations (MBCs) were determined with the broth microdilution method. RESULTS All 20 isolates were confirmed as S. Typhi. The antibiogram phenotype was confirmed as XDR S. Typhi with resistance to ampicillin (≥ 32 µg/mL), ciprofloxacin (≥ 4 µg/mL), and ceftriaxone (≥ 4 µg/mL) and sensitivity to azithromycin (≤ 16 µg/mL) and carbapenems (≤ 1 µg/mL). Molecular conformation revealed the presence of blaTM-1, Sul1, qnrS, gyrA, gyrB, and blaCTX-M-15 genes in all isolates. Among the five honeys, beri honey had the highest zone of inhibition of 7-15 mm and neem honey had a zone of inhibition of 7-12 mm. The MIC and MBC of beri honey against 3/20 (15%) XDR S. Typhi isolates were 3.125 and 6.25%, respectively, while the MIC and MBC of neem were 3.125 and 6.25%, respectively, against 3/20 (15%) isolates and 6.25 and 12.5%, respectively, against 7/20 (35%) isolates. CONCLUSION Indigenous honeys have an effective role in combating XDR S. Typhi. They are potential candidates for clinical trials as alternative therapeutic options against XDR S. Typhi isolates.

Abstract
Covalent organic frameworks (COFs), synthesized from organic monomers, are porous crystalline polymers. Monomers get attached through strong covalent bonds to form 2D and 3D structures. The adjustable pore size, high stability (chemical and thermal), and metal-free nature of COFs make their applications wider. This review article briefly elaborates the synthesis, types, and applications (catalysis, environmental Remediation, sensors) of COFs. Furthermore, the applications of COFs as biomaterials are comprehensively discussed. There are several reported COFs having good results in anti-cancer and anti-bacterial treatments. At the end, some newly reported COFs having anti-viral and wound healing properties are also discussed.

Abstract
Rubella virus (RuV) generally causes a mild infection, but it can sometimes lead to systemic abnormalities. This study aimed to conduct a bibliometric analysis of over two decades of RuV research. Medical studies published from 2000 to 2021 were analyzed to gain insights into and identify research trends and outputs in RuV. R and VOSviewer were used to conduct a bibliometric investigation to determine the globally indexed RuV research output. The Dimensions database was searched with RuV selected as the subject, and 2500 published documents from the preceding two decades were reviewed. The number of publications on RuV has increased since 2003, reaching its peak in 2020. There were 12,072 authors and 16,769 author appearances; 88 publications were single-authored and 11,984 were multi-authored. The United States was the most influential contributor to RuV research, in terms of publications and author numbers. The number of RuV-related articles has continued to increase over the past few years due to the significant rubella burden in low-income nations. This study will aid in formulating plans and policies to control and prevent RuV infections.

Abstract
The monkeypox virus (MPXV) is the cause of a zoonotic infection similar to smallpox. Although it is endemic to Africa, it has recently begun to circulate in other parts of the world. In July 2022, the World Health Organization declared monkeypox an international public health emergency. This review aims to provide an overview of this neglected zoonotic pathogen. MPXV circulates as two distinct clades, the Central African and West African, with case fatality rates of 10.6% and 3.6%, respectively. The risk of infection is greater for those who work with animals or infected individuals. The virus' entry into the human body provokes both natural and acquired immunity. Although natural killer cells, CD4 + T cells, and CD8 + T cells play an essential role in eradicating MPXV, there is still a gap in the understanding of the host immune response to the virus. Currently, there are no specific therapeutic guidelines for treating monkeypox; however, some antiviral drugs such as tecovirimat and cidofovir may help to abate the severity of the disease. The use of nonpharmaceutical interventions and immunization can reduce the risk of infection. Increased surveillance and identification of monkeypox cases are crucial to understand the constantly shifting epidemiology of this resurging and intimidating disease. The present review provides a detailed perspective on the emergence and circulation of MPXV in human populations, infection risks, human immune response, disease diagnosis and prevention strategies, and future implications, and highlights the importance of the research community engaging more with this disease for an effective global response.

Abstract
Human respiratory infections caused by coronaviruses can range from mild to deadly. Although there are numerous studies on coronavirus disease 2019 (COVID-19), few have been published on its Omicron variant. In order to remedy this deficiency, this study undertook a bibliometric analysis of the publishing patterns of studies on the Omicron variant and identified hotspots. Automated transportation, environmental protection, improved healthcare, innovation in banking, and smart homes are just a few areas where machine learning has found use in tackling complicated problems. The sophisticated Scopus database was queried for papers with the term "Omicron" in the title published between January 2020 and June 2022. Microsoft Excel 365, VOSviewer, Bibliometrix, and Biblioshiny from R were used for a statistical analysis of the publications. Over the study period, 1917 relevant publications were found in the Scopus database. Viruses was the most popular in publications for Omicron variant research, with 150 papers published, while Cell was the most cited source. The bibliometric analysis determined the most productive nations, with USA leading the list with the highest number of publications (344) and the highest level of international collaboration on the Omicron variant. This study highlights scientific advances and scholarly collaboration trends and serves as a model for demonstrating global trends in Omicron variant research. It can aid policymakers and medical researchers to fully grasp the current status of research on the Omicron variant. It also provides normative data on the Omicron variant for visualization, study, and application.

Abstract
BACKGROUND Carbapenemase-producing Pseudomonas aeruginosa (CPPA) is a substantial clinical concern because it jeopardizes therapeutic choices. This study characterizes the gene variants of CPPA and report its antibiogram. METHODS CPPA was isolated prospectively from diverse clinical sources in a tertiary care setting using a routine microbiological approach. Carbapenem-resistant P. aeruginosa strains were phenotypically identified using the modified carbapenem inactivation (mCIM) method. Minimum inhibitory concentration (MIC) breakpoints of several antibacterial drug groups were determined using broth microdilution methods and the MicroScan WalkAway plus system. Carbapenemase gene variants blaNDM, blaVIM, blaOXA,blaGES, and blaIMP were amplified using polymerase chain reaction (PCR), and the purified gene products were sequenced. RESULTS Seventy-one P. aeruginosa-infected cases were found, with 47 (66.2%) carrying CPPA; 46.8% of the latter were significantly associated with intensive care units (p = 0.03). CPPA was frequently detected in wound swabs (13; 27.7%), sputum (11; 23.4%), and blood (9; 19.1%). All strains were multidrug-resistant (MDR), and several were extensively drug-resistant. MIC50 and MIC90 breakpoints of all antibiotics, except colistin, were within the resistance range. MIC90 breakpoints of aztreonam, amikacin, cefepime, and piperacillin-tazobactam were > 512 µg/mL. The multiple antibiotic resistance index (MARI) was remarkably high, with a range of 0.38-0.92. The most commonly detected carbapenemase genes were blaVIM (74%), blaNDM-1 (19%), blaOXA-23 (14.9%), and blaGES (10.6%), while 12 of 47 strains co-harbored different combinations of carbapenemase gene variants. CONCLUSION A large proportion of CPPA strains carried the blaVIM gene variant, indicating intimidating health problems and emphasizing the need for extensive surveillance and antibiotic stewardship.

Abstract
Objectives: To evaluate the serum biochemical levels in celiac disease (CD) patients.
Methods: It was a cross-sectional study carried out on 70 subjects, including 40 patients with CD and 30 healthy controls. This study was conducted at Jouf University from November, 2020 to October, 2021. The collected blood specimens were used to perform serum iron, serum lipids, liver enzymes, and human tissue transglutaminase IgA antibodies (anti-HTTG). The hematological parameters including hematocrit and MCV were determined to establish the diagnosis of iron deficiency.
Results: Serum iron was significantly lower in patients as compared to the controls. Serum iron, serum HDL, blood hematocrit and MCV were significantly lower in patients than in controls (p = 0.000). Serum levels of liver enzymes (ALT and AST) and serum human tissue transglutaminase antibodies (anti-HTTG) were significantly higher in patients than in controls (p = 0.000). The correlation studies established the negative correlation of anti-HTTG IgA with serum iron (r = -0.991, p = 0.000), hematocrit (r = -0.967, p = 0.000) and MCV (r = -0.946, p = 0.000) in patients.
Conclusion: The serum iron was remarkably reduced in CD patients. A negative correlation was found between anti-HTTG IgA and serum iron, while a positive serum iron was correlated with hematocrit and MCV in CD patients.

Abstract
Foodborne pathogens have acquired the ability to produce biofilms to survive in hostile environments. This study evaluated biofilm formation, antimicrobial resistance (AMR), and heavy metal tolerance of bacteria isolated from dairy and non-dairy food products. We aseptically collected and processed 200 dairy and non-dairy food specimens in peptone broth, incubated them overnight at 37 °C, and sub-cultured them on various culture media. Bacterial growth was identified with biochemical tests and API 20E and 20NE strips. The AMR of the isolates was observed against different antibacterial drug classes. Biofilm formation was detected with the crystal violet tube method. Heavy metal salts were used at concentrations of 250−1500 µg/100 mL to observe heavy metal tolerance. We isolated 180 (50.4%) bacteria from dairy and 177 (49.6%) from non-dairy food samples. The average colony-forming unit (CFU) count for dairy and non-dairy samples was 2.9 ± 0.9 log CFU/mL and 5.1 ± 0.3 log CFU/mL, respectively. Corynebacterium kutscheri (n = 74), lactobacilli (n = 73), and Staphylococcus aureus (n = 56) were the predominant Gram-positive and Shigella (n = 10) the predominant Gram-negative bacteria isolated. The correlation between biofilm formation and AMR was significant (p < 0.05) for most cephalosporins, aminoglycosides, and fluoroquinolones. Heavy metal tolerance tended to be higher in biofilm producers at different metal concentrations. The pathogens isolated from dairy and non-dairy food showed a high burden of AMR, high propensity for biofilm formation, and heavy metal tolerance, and pose an imminent threat to public health.

Abstract
The emergence of carbapenem-resistant Acinetobacter calcoaceticus-baumannii complex (CRACB) in clinical environments is a significant global concern. These critical pathogens have shown resistance to a broad spectrum of antibacterial drugs, including carbapenems, mostly due to the acquisition of various β-lactamase genes. Clinical samples (n = 1985) were collected aseptically from multiple sources and grown on blood and MacConkey agar. Isolates and antimicrobial susceptibility were confirmed with the VITEK-2 system. The modified Hodge test confirmed the CRACB phenotype, and specific PCR primers were used for the molecular identification of blaOXA and blaNDM genes. Of the 1985 samples, 1250 (62.9%) were culture-positive and 200 (43.9%) were CRACB isolates. Of these isolates, 35.4% were recovered from pus samples and 23.5% from tracheal secretions obtained from patients in intensive care units (49.3%) and medical wards (20.2%). An antibiogram indicated that 100% of the CRACB isolates were resistant to β-lactam antibiotics and β-lactam inhibitors, 86.5% to ciprofloxacin, and 83.5% to amikacin, while the most effective antibiotics were tigecycline and colistin. The CRACB isolates displayed resistance to eight different AWaRe classes of antibiotics. All isolates exhibited the blaOXA-51 gene, while blaOXA-23 was present in 94.5%, blaVIM in 37%, and blaNDM in 14% of the isolates. The blaOXA-51, blaOXA-23, and blaOXA-24 genes co-existed in 13 (6.5%) isolates. CRACB isolates with co-existing blaOXA-23, blaOXA-24, blaNDM, blaOXA-51 and blaVIM genes were highly prevalent in clinical samples from Pakistan. CRACB strains were highly critical pathogens and presented resistance to virtually all antibacterial drugs, except tigecycline and colistin.

Abstract
The 5-hydroxytryptamine receptor 6 (5-HT6) has gained attention as a target for developing therapeutics for Alzheimer’s disease, schizophrenia, cognitive dysfunctions, anxiety, and depression, to list a few. In the present analysis, a larger and diverse dataset of 1278 molecules covering a broad chemical and activity space was used to identify visual and concealed structural features associated with binding affinity for 5-HT6. For this, quantitative structure–activity relationships (QSAR) and molecular docking analyses were executed. This led to the development of a statistically robust QSAR model with a balance of excellent predictivity (R2tr = 0.78, R2ex = 0.77), the identification of unreported aspects of known features, and also novel mechanistic interpretations. Molecular docking and QSAR provided similar as well as complementary results. The present analysis indicates that the partial charges on ring carbons present within four bonds from a sulfur atom, the occurrence of sp3-hybridized carbon atoms bonded with donor atoms, and a conditional occurrence of lipophilic atoms/groups from nitrogen atoms, which are prominent but unreported pharmacophores that should be considered while optimizing a molecule for 5-HT6. Thus, the present analysis led to identification of some novel unreported structural features that govern the binding affinity of a molecule. The results could be beneficial in optimizing the molecules for 5-HT6.

Abstract
The adenosine nucleoside performs a wide range of actions on various human tissues by activating four cell surface receptors. Adenosine A2A receptors (A2ARs) are widely expressed in the striatum, olfactory bulb, platelets, leukocytes, spleen, and thymus. They promote vasodilatation, platelet antiaggregatory effect, protection from ischemic damage, and regulation of sensorimotor neurons in basal ganglia. Adenosine signaling plays a vital part in modulating in vivo pathophysiological responses. A2ARs are potent negative regulators of the antitumor and proinflammatory actions of activated T cells. This axis offers several therapeutic targets, the most important of which are A2ARs, HIF-1α, and CD39/CD73. Downregulation of this axis increases the effectiveness of modern immunotherapeutic approaches against cancer, such as αCTLA-4/αPD-1. These discoveries have led to a promising novel role of antagonists of A2AR in blocking angiogenesis in immunotherapy of cancer. A small molecule, AZD4635, strongly inhibits A2AR, lowering cancer volume and increasing anticancer immunity. Deletion of A2AR with CRISPR/Cas9 in both human and murine CAR T cells produces a substantial increase in the efficiency of these cells. This review asserts that inhibition of the adenosinergic pathway can boost antitumor immunity, and this axis should be a target for future immunotherapeutic strategies.

Abstract
Background Citrus aurantifolia Linn. fruit, a natural dietary item, has long been used traditionally to treat hypertension in Pakistan. The current research work aims to explore the effect on blood pressure and its mechanisms. Methods The aqueous methanol extract of plant fruit was used to evaluate hypotensive/antihypertensive, vasorelaxation, and safety profiles. Moreover, the in vitro inhibitory effect of AMECA on phosphodiesterase was also evaluated. Results In hypotensive studies, extracts of Citrus aurantifolia fruit exhibited a concentration-dependent reduction in SBP, DBP, MAP, and heart rate. A similar effect has been observed on anesthetized rats, but the effects exerted by the extract were not altered significantly in the presence of L-NAME, atropine, captopril, and propranolol. Moreover, in coronary arteries, the extract significantly potentiated relaxations induced by cGMP- and cAMP-dependent relaxing agonists. When exposed to PDEs, the extract concentration dependently subdued cGMP-hydrolyzing activity of different PDEs with IC50 values of 40-130 μg/mL. Conclusion It is conceivable that extracts obtained from Citrus aurantifolia fruit produced hypotensive and antihypertensive effects in rats. The extract elicited endothelium-independent vasorelaxation, possibly by acting directly on smooth muscles of the coronary artery and by increasing cGMP and cAMP via nonselective inhibition of vascular PDEs.

Abstract
Mimosa pudica seed mucilage (MPM) is composed of glucuronoxylan, which is a swellable, pH-responsive and non-toxic biomaterial. Herein, we aimed to extract MPM from M. pudica seeds (MP seeds) to ascertain optimization of extraction conditions to get highest yield by response surface methodology, via Box-Behnken design (RSM-BBD). MPM was extracted from MP seeds by a hot water extraction method. The effects of four different parameters on the extraction yield of MPM were evaluated: pH of the extraction medium (1–10), seed/water contact time (1–12 h), the temperature of extraction medium (30–90 °C), and seed/water ratio (1:5–1:35 w/v). The maximum yield of MPM obtained by Design-Expert software was 10.66% (10.66 g/100 g) at pH 7, seed/water contact time of 6 h, extraction temperature of 50 °C, and seed/water ratio of 1:20 w/v. The p values of ANOVA were found to be less than 0.0001, which indicated that the extraction yield of MPM was significantly affected by all the study parameters. The results revealed that pH and extraction temperature were the most significant factors affecting the yield of MPM. MPM in compressed tablet form showed pH-responsive on–off switching behavior at pH 7.4 and 1.2 in a reversible manner. MPM in compressed tablet form sustained the release of itopride for 16 h following a super case-II transport mechanism and zero-order release kinetics.

Abstract
New furan-based derivatives have been, designed, synthesized, and evaluated for their cytotoxic and tubulin polymerization inhibitory activities. DNA flow cytometric study of pyridine carbohydrazide 4 and N-phenyl triazinone 7 demonstrated G2/M phase cell cycle disruptions. Accumulation of cells in the pre-G1 phase and positive annexin V/PI staining, which may be caused by degeneration or fragmentation of the genetic components, suggested that cell death occurs via an apoptotic cascade. Furthermore, compounds 4 and 7 had a strong pro-apoptotic impact through inducing the intrinsic mitochondrial mechanism of apoptosis. This mechanistic route was verified by an ELISA experiment that indicated a considerable rise in the levels of p53 and Bax and a drop in the level of Bcl-2 when compared with the control.

Abstract
The rapid progression in biomaterial nanotechnology apprehends the potential of non-toxic and potent polysaccharide delivery modules to overcome oral chemotherapeutic challenges. The present study is aimed to design, fabricate and characterize polysaccharide nanoparticles for methotrexate (MTX) delivery. The nanoparticles (NPs) were prepared by Abelmoschus esculentus mucilage (AEM) and chitosan (CS) by the modified coacervation method, followed by ultra-sonification. The NPs showed much better pharmaceutical properties with a spherical shape and smooth surface of 213.4–254.2 nm with PDI ranging between 0.279–0.485 size with entrapment efficiency varying from 42.08 ± 1.2 to 72.23 ± 2.0. The results revealed NPs to possess positive zeta potential and a low polydispersity index (PDI). The in-vitro drug release showed a sustained release of the drug up to 32 h with pH-dependence. Blank AEM -CS NPs showed no in-vivo toxicity for a time duration of 14 days, accompanied by high cytotoxic effects of optimized MTX loaded NPs against MCF-7 and MD-MBA231 cells by MTT assay. In conclusion, the findings advocated the therapeutic potential of AEM/CS NPs as an efficacious tool, offering a new perspective for pH-responsive routing of anticancer drugs with tumor cells as a target.

Abstract
Emerging extensively drug-resistant (XDR) Klebsiella pneumoniae due to the production of β-lactamases and porin loss is a substantial worldwide concern. This study aimed to elucidate the role of outer membrane porin (OMP) loss, AmpC, and carbapenemases among extended-spectrum β-lactamase (ESBL)-producing K. pneumoniae strains with XDR phenotype. This study analyzed 79 K. pneumoniae from several clinical sources and detected ESBLs in 29 strains co-harbored with other β-lactamases using standard microbiological practices and phenotypic procedures. Minimum inhibitory concentrations (MICs) were determined against several antibiotics using Microscan WalkAway plus. OMP analysis was carried out using sodium dodecyl sulfate–polyacrylamide gel electrophoresis. ESBL, AmpC, and carbapenemase genes were detected using molecular methods. The microbiological analysis discovered 29 (36.7%) ESBL strains of K. pneumoniae, which showed the co-existence of 7 (24.1%) AmpC β-lactamases and 22 (75.9%) carbapenemases. Porin loss of OmpK35 was observed in 13 (44.8%) and OmpK36 in 8 (27.5%) K. pneumoniae strains. The strains were significantly associated with the intensive care unit (ICU) (p = 0.006) and urinary sources (p = 0.004). The most commonly detected gene variants in each β-lactamase class included 16 (55.2%) blaCTX-M−1, 7 (100%) blaCYM-2, 11 (50%) blaNDM-1, and integron-1 was detected in 21/29 (72.4%) strains. MICs of cephalosporin, fluoroquinolone, carbapenem, aminoglycoside, and β-lactam combinations demonstrated a high number of XDR strains. Tigecycline (2 µg/mL MIC50 and >32 µg/mL MIC90) and colistin (1 µg/mL MIC50 and 8 µg/mL MIC90) presented lower resistance. ESBL K. pneumoniae strains with OmpK35 and OmpK36 porin loss demonstrate conglomerate resistance mechanisms with AmpC and carbapenemases, leading to emerging XDR and pan drug resistance.

Abstract
This study aimed to find out the prevalence and antimicrobial resistance profile of Klebsiella pneumoniae in raw food items. A total of 261 raw food items, including vegetables, fruits, meat, and milk samples, were collected and processed for isolation of K. pneumoniae. Further antimicrobial susceptibility testing and molecular analysis was done to analyze the drug resistance encoding genes. The prevalence rate of K. pneumoniae was found to be high (38%), and the raw milk samples were predominantly contaminated (19/51), followed by fruits (12/51), meat (11/51), and vegetables (9/51). However, no significant association was observed for the isolation of K. pneumoniae and any particular specimen. Among the isolates, 43% were extended-spectrum β-lactamase producers, 24% were AmpC, and 20% were carbapenemase producers. The highest rates of ESBLs and AmpC were observed in vegetables (cabbage, bell pepper, and spinach) and carbapenemases in raw chicken, fish, and raw meat samples. Notably, blaCTX-M was the most prevalent, followed by blaSHV and blaTEM. Six K. pneumoniae possessed blaMOX, and five possessed blaFOX genes. Numerous carbapenemases were identified with a higher proportion of blaNDM. This study indicates that raw vegetables, fruits, meat, and milk are exposed to contaminants. These findings imply a potential threat that drug-resistant K. pneumoniae pathogens could transmit to humans through raw vegetables, fruits, and meat.

Abstract
Aims: We aimed to investigate the occurrence of the rubella virus among pregnant women, including those who had a history of abortions in the Red Sea region of Sudan.
Study design: Cross-sectional study.
Place and Duration of Study: The study was conducted at the Port Sudan referral tertiary hospital.
Methodology: Blood samples were collected at random from 100 participants who were pregnant or had a history of abortion and who were referred to the hospital. Side flow chromatography immunoassay was used for detection, and the Elisa technique was used for confirmation.
Results: From a total of 100 participants, rubella virus Immunoglobulin G (IgG) was detected in 20 (20%), and 80 were seronegative (80%). The seronegative Immunoglobulin M (IgM) was 0 (00.0%), with no participant had a recent infection. The prevalence of 11 rubella virus IgG was significantly high (P = .003) among the females who had abortions 61 (61%). However, no statistically significant relationship was found with the frequency of IgG of rubella virus and age, gestational age, level of education, or occupation.
Conclusion: The study concluded that the prevalence of rubella infections was higher among pregnant females and who had a history of abortions in the Red Sea region. The detection of human rubella virus IgG previous infection was higher than IgG recent infection.

Abstract
INTRODUCTION The conventional interferon therapy of hepatitis C virus has been substituted substantially with sofosbuvir and daclatasvir due to constraints in efficacy and tolerability. This study aimed diagnostically to monitor the effectiveness and side effects of direct-acting antivirals in the management of HCV infections. METHODOLOGY This prospective study was conducted on HCV-infected patients treated with sofosbuvir and daclatasvir. Different serological, biochemical, hematological, and molecular techniques were used for the assessment of patients. Only treatment-naive patients aged ≥ 18 to 75 years received 12 weeks of treatment. The primary endpoint was a sustained virologic response with undetectable HCV RNA in the patients' serum at the end of the treatment. RESULTS We identified 229 cases of confirmed HCV infections by PCR, 94.3% of which had genotype 3. The study population comprised 66% females and 34% males with a median age of 42.2 ± 10.6 SD. Ninety-three percent of the patients accomplished SVR at week 12. The combined therapy of SOF/DAC achieved the highest efficacy rate (92.6%) among the different HCV genotype 3 patients. A statistically significant relationship was observed between low baseline viral load (p < 0.001; 95% CI = 1.2-3.1) and HCV genotype 3 with minor side effects, including lethargy, headache, nausea, insomnia, diarrhea, and fever. CONCLUSIONS HCV-infected patients can be treated well with an interferon-free SOF/DAC regimen, tolerated with generally mild adverse effects with a higher SVR.

Abstract
Coronavirus disease-19 (COVID-19) is an extremely infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has become a major global health concern. The induction of a coordinated immune response is crucial to the elimination of any pathogenic infection. However, SARS-CoV-2 can modulate the host immune system to favor viral adaptation and persistence within the host. The virus can counteract type I interferon (IFN-I) production, attenuating IFN-I signaling pathway activation and disrupting antigen presentation. Simultaneously, SARS-CoV-2 infection can enhance apoptosis and the production of inflammatory mediators, which ultimately results in increased disease severity. SARS-CoV-2 produces an array of effector molecules, including nonstructural proteins (NSPs) and open-reading frames (ORFs) accessory proteins. We describe the complex molecular interplay of SARS-CoV-2 NSPs and accessory proteins with the host's signaling mediating immune evasion in the current review. In addition, the crucial role played by immunomodulation therapy to address immune evasion is discussed. Thus, the current review can provide new directions for the development of vaccines and specific therapies.

Abstract
OBJECTIVE Single nucleotide polymorphisms (SNPs) in IL28B and IL10 regions are important in predicting the antiviral response in hepatitis C virus (HCV) patients. In this study, the association of IL28B and IL10 genetic polymorphisms and other clinical factors was assessed as a predictive marker for the sustained virological response (SVR) of HCV patients taking direct-acting antivirals (DAAs). METHODS We processed 384 serum specimens of HCV serology positive cases for qualitative and quantitative polymerase chain reaction (PCR). Patients were followed up for 12 weeks after the start of antiviral therapy, and the viral load was monitored at each time point. IL28B and IL10 polymorphisms (rs8103142 and rs12980275, rs1800872 and rs3021094, respectively) were detected by real-time PCR, followed by melt curve analysis for genotyping. RESULTS This study's findings indicate an independent association of SVR with high basal viral load (P=0.005) and an HCV genotype other than 3 (P=0.001). Patients with viral load log10 >6.5 IU/mL required more days to reach an undetectable viral RNA load. The results of the genetic analysis showed a significant association of rs8103142 genotype CC (P<0.01) and rs12980275 genotype AA (P=0.01) with non-SVR. Both SNPs showed an independent association in the multivariate analysis. CONCLUSION High basal viral load, HCV genotype, and host polymorphisms of rs8103142 and rs12980275 have an independent association in predicting the therapeutic response of HCV patients. The preliminary identification of polymorphisms prior to treatment will help in predicting the outcome of therapy.

Abstract
Background The therapeutic management of carbapenem-resistant Acinetobacter baumannii (CR-AB) represents a serious challenge to the public health sector because these pathogens are resistant to a wide range of antibiotics, resulting in limited treatment options. The present study was planned to investigate the clonal spread of CR-AB in a clinical setting. Methodology A total of 174 A. baumannii clinical isolates were collected from a tertiary care hospitals in Lahore, Pakistan. The isolates were confirmed by VITEK 2 compact system and molecular identification of recA and blaOXA-51. Antimicrobial profile and the screening of carbapenem-resistant genes were carried out using VITEK 2 system and PCR, respectively. The molecular typing of the isolates was performed according to the Pasteur scheme. Results Of the 174 A. baumannii isolates collected, the majority were isolated from sputum samples (46.5%) and in the intensive care unit (ICU, 75%). Among these, 113/174 (64.9%) were identified as CR-AB, and 49.5% and 24.7% harbored blaOXA-23 and blaNDM-1, respectively. A total of 11 (9.7%) isolates co-harbored blaOXA-51, blaNDM-1, and blaOXA-23. Interestingly, 46.9% of the CR-AB belonged to sequence type 2 (ST2; CC1), whereas 15.9% belonged to ST1 (CC1). All of the CR-AB isolates showed extensive resistance to clinically relevant antibiotics, except colistin. Conclusion The study concluded CR-AB ST2 clone harboring blaOXA-23 and blaNDM-1 are widely distributed in Pakistan’s clinical settings, which could result in increased mortality. Strict compliance with the National Action Plan on Antimicrobial Resistance is necessary to reduce the impacts of these strains.

Abstract
This study evaluates bacteriological profiles in ready-to-eat (RTE) foods and assesses antibiotic resistance, extended-spectrum β-lactamase (ESBL) production by gram-negative bacteria, and heavy metal tolerance. In total, 436 retail food samples were collected and cultured. The isolates were screened for ESBL production and molecular detection of ESBL-encoding genes. Furthermore, all isolates were evaluated for heavy metal tolerance. From 352 culture-positive samples, 406 g-negative bacteria were identified. Raw food samples were more often contaminated than refined food (84.71% vs. 76.32%). The predominant isolates were Klebsiella pneumoniae (n = 76), Enterobacter cloacae (n = 58), and Escherichia coli (n = 56). Overall, the percentage of ESBL producers was higher in raw food samples, although higher occurrences of ESBL-producing E. coli (p = 0.01) and Pseudomonas aeruginosa (p = 0.02) were observed in processed food samples. However, the prevalence of ESBL-producing Citrobacter freundii in raw food samples was high (p = 0.03). Among the isolates, 55% were blaCTX-M, 26% were blaSHV, and 19% were blaTEM. Notably, heavy metal resistance was highly prevalent in ESBL producers. These findings demonstrate that retail food samples are exposed to contaminants including antibiotics and heavy metals, endangering consumers.

Abstract
Plasmid-mediated colistin resistance (Col-R) conferred by mcr genes endangers the last therapeutic option for multifarious β-lactamase-producing bacteria. The current study aimed to explore the mcr gene molecular epidemiology in extensively drug-resistant (XDR) bacteria. Col-R gram-negative bacterial strains were screened using a minimum inhibitory concentration (MIC) breakpoint ≥4 µg/mL. Resistant isolates were examined for mcr variants, extended-spectrum β-lactamase, AmpC, and carbapenemase genes using polymerase chain reaction (PCR). The MIC breakpoints for mcr-positive strains were determined using broth microdilution and E-test strips. Overall, 19/718 (2.6%) gram-negative rods (GNRs) harboring mcr were identified, particularly in pus (p = 0.01) and tracheal secretions (p = 0.03). Molecular epidemiology data confirmed 18/19 (95%) mcr-1 and 1/19 (5%) mcr-2 genes. Integron detection revealed 15/17 (88%) Int-1 and 2/17 (12%) Int-2. Common co-expressing drug-resistant β-lactamase genes included 8/16 (50%) blaCTM-1, 3/16 (19%) blaCTM-15, 3/3 (100%) blaCMY-2, 2/8 (25%) blaNDM-1, and 2/8 (25%) blaNDM-5. The MIC50 and MIC90 values (µg/mL) were as follows: Escherichia coli, 12 and 24; Klebsiella pneumoniae, 12 and 32; Acinetobacter baumannii, 8 and 12; and Pseudomonas aeruginosa, 32 and 64, respectively. Treatment of XDR strains has become challenging owing to the co-expression of mcr-1, mcr-2, multifarious β-lactamase genes, and integrons.

Abstract
Background Type 2 diabetes mellitus (T2DM) is the most prevalent component of metabolic syndrome. Environmental factors and various complex genes like transcription factor 7-like 2 (TCF7L2) gene have involved in the disease development. Objective To determine TCF7L2 genetic association (rs7903146C/T and rs12255372G/T) in T2DM patients of Khyber Pakhtunkhwa population of Pakistan. Subjects and methods This study comprised of 176 subjects including 118 T2DM patients and 58 healthy controls. Genomic DNA was extracted and genotype of common variants (rs7903146 C/T and rs12255372 G/T) was carried out by amplification-refractory mutation system (ARMS)-PCR of sequence specific oligonucleotides. Results The distribution of genotype of TCF7L2 SNPs (rs7903146 C/T and rs12255372 G/T) was significantly associated with T2DM as compared to the controls (p <0.0001). The genetic models of the rs7903146 (C/T) and rs12255372 (G/T) SNPs were significantly associated between cases and controls (p <0.0001). On the other hand, the significant association was observed between the two SNPs and different biochemical parameters like serum fasting glucose, lipid profile, creatinine and blood HbA1c levels (p <0.05). Conclusion It is concluded that the SNPs of the TCF7L2 gene are significantly associated with T2DM disease susceptibility in the population of Khyber Pakhtunkhwa of Pakistan.

Abstract
Objectives: To detect the relationship between serum tumor necrosis factor-alpha (TNF-α) and metabolic syndrome (MetS) components in patients of the Saudi population. Methods: This cross-sectional study was carried out at Jouf University Saudi Arabia from September 2019 to August 2020 and comprised of 183 individuals (91 cases and 92 controls). The blood samples were drawn from the patients visiting two tertiary care settings of Al Jouf province. Biochemical analysis was conducted on various instruments, and serum TNF-α was measured by the ELISA method. Results: The levels of serum glucose fasting, lipid profile, HbA1c and body mass index (BMI) were raised significantly in cases of MetS than controls (p = 0.001). Serum TNF-α was significantly higher in patients (58.04 ± 15.44) than controls (48.81 ± 10.30). It was correlated with the BMI, blood HbA1c, serum fasting glucose (SFG) and serum high density lipoprotein (HDL). The weak positive correlation was found with BMI (r = 0.18; p = 0.01), serum glucose (r = 0.21; p = 0.007) and HbA1c (r = 0.14; p = 0.04), but found negative association with serum HDL (r = -0.18; p = 0.01). Conclusion: The serum TNF-α was raised in metabolic syndrome patients than the healthy controls. It was positively associated with high BMI, serum fasting glucose, and HbA1c and found linked and negatively linked to low HDL levels in MetS patients in the Saudi population.

Abstract
Colonization of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae as animal gut microbiota is a substantial global threat. This study aimed to determine the molecular characterization of blaSHV, blaTEM, and blaCTX-M variants in animals, as well as to evaluate the antimicrobial resistance conferred by these genes. We prospectively analyzed 1273 fecal specimens of farm and domestic animals for the isolation of enterobacteria that had the ESBL phenotype by using biochemical methods. The extracted genes were amplified by polymerase chain reaction and sequenced for the characterization of blaSHV, blaTEM, and blaCTX-M variants. The drug-resistance spectrum and hierarchical clusters were analyzed against 19 antibacterial agents. Out of 245 (19.2%) ESBL enterobacteria, 180 (75.5%) Escherichia coli and 34 (13.9%) Klebsiella pneumoniae were prevalent species. A total of 73.9% blaCTX-M, 26.1% blaTEM, and 14.2% blaSHV were found among the enterobacteria; however, their association with farm or domestic animals was not statistically significant. The distribution of bla gene variants showed the highest number of blaCTX-M-1 (133; 54.3%), followed by blaCTX-M-15 (28; 11.4%), blaTEM-52 (40; 16.3%), and blaSHV-12 (22; 9%). In addition, 84.5% of the enterobacteria had the integrons intI1. We observed ±100% enterobacteria resistant to cephalosporin, 7 (2.9%) to colistin (minimum inhibitory concentration breakpoint ≥4 μg/mL), 9 (3.7%) to piperacillin-tazobactam, 11 (4.5%) to imipenem, 14 (5.7%) to meropenem, and 18 (7.3%) to cefoperazone-sulbactam, without statistically significant association. Animal gut microbiota contain a considerable number of blaCTX-M, blaTEM, blaSHV, and integrons, which are a potential source of acquired extensive drug resistance in human strains and leaves fewer therapeutic substitutes.

Abstract
Carbapenem resistance in Pseudomonas aeruginosa is a major concern in the public health sector, primarily in developing countries such as Pakistan. Therefore, novel approaches such as Silver nanoparticles (AgNPs) can be used to address emerging concerns. Clinical isolates (n=200) were reconfirmed using selective media and API 20NE kit. The antibiogram was determined according to the CLSI 2016 guidelines. Molecular detection was carried out by PCR. Antibacterial activity in AgNPs was achieved by dilution method. Of 200 P. aeruginosa, mostly (n=82; 41%) were isolated from pus samples. Of 110 MDR P. aeruginosa, 70 (63%) were carbapenemase and 58 (52%) were MBL producers. Antimicrobial profile of MBL producing P. aeruginosa reported that all isolates were resistant to β-lactams, and 89% to levofloxacin and ciprofloxacin except colistin. Of 25 (35.7%) blaNDM producing P. aeruginosa, 12 isolates (48%) had MIC 16μg/mL to imipenem. Of 23 (32%) blaVIM producing P. aeruginosa, 12 (52%) contained MIC 16μg/mL to imipenem. However, 12 (17.1%) blaOXA-48 producing P. aeruginosa, 4 (33%) contained MIC 16μg/mL to imipenem. In vitro AgNPs activity inhibited and killed MBL producing isolates at 1 mg/mL and 2 mg/mL, respectively. AgNPs may be used as an alternative therapy followed by multiple clinical trials.

Abstract
BACKGROUND The emergence of the New Dehli metallo-beta-lactamase (NDM) gene in Enterobacteriaceae is responsible for multidrug resistance responsible for severe infections and serious morbidity in patients. Our study aimed to define the molecular characteristics and antibiogram of the NDM-1 producing Enterobacteriaceae. METHODS We isolated 370 individual enterobacteria from the clinical specimens collected from the two tertiary hospitals in Sakaka, Saudi Arabia. Bacterial isolation was performed using standard microbiological techniques and the Phoenix and Microscan WalkAway Plus automated analyzers. Bacterial strains were characterized by phenotypic methods and PCR, and DNA sequencing was used for the molecular characterization of NDM genes. RESULTS The blaNDM gene was detected among the 68 members of the Enterobacteriaceae including a single case of rarely reported Cedecea lapagei. Of these 68, 43 isolates (63.2%) were blaNDM-1 and 25 (36.8%) were blaNDM variants. A statistically significant relationship between the NDM-1 and Klebsiella pneumoniae (p = 0.004) was seen, and the relationship between the NDM variants was significantly associated with Citrobacter freundii (p = 0.02) and Escherichia coli (p = 0.03). The in vitro minimum inhibitory concentrations (MICs) of NDM-producing Enterobacteriaceae revealed a very high rate of antibiotic resistance against several groups of antibiotics. These bacterial strains were less resistant to two aminoglycosides, gentamicin (39; 57.3%) and amikacin (27; 39.7%), and showed minimum resistance to tigecycline (25; 36.8%). CONCLUSIONS The emergence of a large number of NDM-1 enterobacteria in our study identifies a substantial public concern, both within hospitals and the wider community, and leaves us a narrow choice of therapeutic options: the aminoglycosides, co-trimoxazole, and tigecycline.

Abstract
The evolution of antimicrobial-resistant Gram-negative pathogens is a substantial menace to public health sectors, notably in developing countries because of the scarcity of healthcare facilities. New Delhi metallo-β-lactamase (NDM) is a potent β-lactam enzyme able to hydrolyze several available antibiotics. NDM was identified from the clinical isolates of Klebsiella pneumoniae and Escherichia coli from a Swedish patient in New Delhi, India. This enzyme horizontally passed on to various Gram-negative bacteria developing resistance against a variety of antibiotics which cause treatment crucial. These bacteria increase fatality rates and play an integral role in the economic burden. The efficient management of NDM-producing isolates requires the coordination between each healthcare setting in a region. In this review, we present the prevalence of NDM in children, fatality and the economic burden of resistant bacteria, the clonal spread of NDM harboring bacteria and modern techniques for the detection of NDM producing pathogens.

Abstract
OBJECTIVE Dissemination of extended-spectrum beta-lactamase (ESBL) genotypes in Pseudomonas aeruginosa gained attention as superbugs, which are extremely difficult to treat with conventional antibiotics. The study aimed to delineate the empirical therapy and the occurrence of SHV, TEM, and CTX-M encoding P. aeruginosa among pediatric patients. METHODS A total number of 33,400 continuous and non-repetitive clinical specimens collected from the debilitated pediatric patients processed for the isolation of P. aeruginosa. The characterization of the isolated strains performed using phenotypic and molecular methods. The spectrum of antibacterial resistance observed against all the isolated strains of P. aeruginosa. RESULTS: A total of 74 (18.8%) ESBL producers isolated, out of which 58 (78.4%) were bla CTX-M, 53 (71.6%) bla SHV, and 38 (51.4%) were bla TEM genes. The mortality was significantly associated (p<0.001) in patients infected with ESBL producing P. aeruginosa and neonatal age group. The mean length of stay for the patients infected with ESBL and non-ESBL producing P. aeruginosa was 7.93±7.26 and 8.26±5.40, respectively. Antibiogram showed high resistance of spectrum with cephalosporins while resistance against cefoperazone-sulbactam (32; 43.2%), carbapenems (23; 31.1%), and piperacillin-tazobactam (14; 18.9%) was comparatively low. CONCLUSION The dissemination and co-existence of bla CTX-M, bla SHV, and bla TEM genes in P. aeruginosa clones make it difficult to treat the infected pediatric patients without the new synergistic combinational regimens.

Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) has imperiled human lives and global infrastructure since the emergence of SARS-CoV-2 in China. The current review meticulously summarizes the COVID-19 pandemic situation through the lens of science from the inception of the outbreak to the current progression, which is valuable to mitigate the current pandemic situation. METHODS We reviewed all the relevant literature available on PubMed, Web of Sciences, Google Scholar, and World Health Organization (WHO) website related to COVID-19 from the inception of the outbreak to 18 June 2020. We selected ninety different scientific studies and reports to compile the current review. RESULTS Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a betacoronavirus with four major structural proteins encoded by S, M, E, and N genes and distinct in morphology. The potential provenance of SARS-Cov-2 is zoonotic, and it binds to the host cell receptors by spike protein. The SARS-CoV-2 infectious cycle carries on through direct contact, air, inanimate objects, and contaminated surfaces. The reproductive number (R0) of SARS-CoV-2 is 2 to 3.5, representing that one infected patient can spread this virus to two to three people. An expeditious laboratory diagnosis has a pivotal role in patient management and prevention. Due to the lack of definitive treatment, symptomatic medication regimen and supportive organ therapies are adapted for debilitated patients. CONCLUSIONS Nucleoside analogs and protease-inhibitors have approved to attenuate the viral infection until the discovery of a specific drug. The other treatment strategies comprise antimalarial drugs, monoclonal antibodies, and glucocorticoids. The use of alcoholic scrubs, sodium hypochlorite, masks, social distancing, and quarantine the affected individual is inevitable to eradicate the infection vector and to break the transmission path.

Abstract
The third coronavirus outbreak in the last two decades has caused significant damage to the world's economy and community health. The highly contagious COVID-19 infection has affected millions of people to date and has led to hundreds of thousands of deaths worldwide. Aside from the highly infectious nature of SARS-CoV-2, the lack of a treatment or vaccine has been the main reason for its spread. Thus, it has become necessary to find alternative methods for controlling SARS-CoV-2. For the present review, we conducted an online search for different available nutrition-based therapies for previously known coronavirus infections and RNA-based virus infections as well as general antiviral therapies. These treatments have promise for combating COVID-19, as various nutrients and minerals play direct and indirect roles in the control and prevention of this newly emerged viral infection. The patients' nutritional status with COVID-19 must be analyzed before administering any treatment, and nutritional supplements should be given to the affected individuals along with routine treatment. We suggest a potential interventional role of nutrients to strengthen the immune system against the emerging infection caused by COVID-19.

Abstract
Background: The emergence of AmpC beta-lactamase producing Enterobacter cloacae becomes a serious nosocomial menace due to wider resistance. The study aimed to know the existence of these superbugs in the hospital settings and to report the current trends in their antibiotic resistance.
Methods: We chose a tertiary care pediatric hospital for this cross-sectional study and processed 27,000 clinical specimens for the isolation of E. cloacae using routine microbiological procedures. A total number of 96 E. cloacae isolates from various sources were screened for AmpC production with cefoxitin (30 μg) and confirmed by inhibitor based technique. The antibacterial drug resistance studied against various groups of antibiotics in vitro.
Results : Boronic acid inhibitor based method revealed 63 (65.6%) pathogens as AmpC beta-lactamase producing E. cloacae. Most of the infected patients with AmpC producing E. cloacae were neonates (34; 54.0%) and infants (11; 17.5%). The primary source of AmpC producing E. cloacae was blood (43; 68.3%), and they were frequently distributed in the neonatal nursery unit (33; 52.4%) and medical ward (13; 20.6%). All of these bugs showed a high level of resistance (100%) against the co-amoxiclav and cephalosporin group.The organisms exhibited less resistance to levofloxacin, imipenem and colistin sulphate as 23 (36.5%), 20 (31.7%) and 17 (27.0%), respectively.
Conclusion: The consistent emerging threat of Amp C harbouring E. cloacae could disseminate AmpC genes in other genera of the bacteria which lead to the therapeutic failure and leave the doctors with limited treatment options of levofloxacin, imipenem and colistin sulphate.

Abstract
Objective: To gauge the recent breadth of MDR E. coli along with antibiogram of carbapenemase producing (CP) E. coli among children from an institute which receives patients from all over Punjab. Methods: The bacterial strains of E. coli isolated from various specimens of patients were collected from April 2017 to August 2018 and processed using standard biochemical tests and API 20E system (bioMerieux). Phenotypic screening for CP E. coli was done by the modified Hodge test, whereas antibiotic susceptibility testing was done with Kirby-Bauer disc diffusion technique. Results: Total of 6,468 bacterial strains were isolated, out of which 1,552 (24%) were E. coli. Carbapenem resistance was observed in 245 (16%) strains, amongst which 113 (46%) were confirmed to be CP. E. coli isolated from males were higher as compared to females (p<0.05). Majority of the organisms were isolated from blood (37.2%) samples. The hospital discharged about 65% of patients, while 23% left against medical advice. Overall MDR amongst E. coli was 93.26%. Colistin sulphate (15.9%) and nitrofurantoin (16.8%) showed the most efficacy followed by amikacin (15%) and fosfomycin (10.6%). Conclusion: The isolation of high number of MDR E. coli amongst the paediatric patients is worrisome, which could serve as a potential source of horizontal genes transfer to other genera.

Abstract
Objectives: Emerging cases of vancomycin-resistant enterococci (VRE) are detrimental for the patients. The current study aimed to ascertain the occurrence of VRE, their antibiogram and the van genotype responsible for vancomycin resistance. Methods: A total number of 2,958 clinical specimens were processed at Microbiology Department of the Alrazi Health Care, Lahore during the one year (2016-2017) using microbiological culture media, biochemical and serology. Antibiogram of enterococcal strains was performed using disc diffusion and E-test. ATCC Enterococcus faecalis 29212 was used as a quality control strain. The detection of van genotypes was accomplished by multiplex PCR assay. Results: Out of the 147 enterococci, 139 (94.6%) were E. faecalis, and 8 (5.4%) were E. faecium. Statistically significant associations of urine (p < 0.001), pus (p < 0.001) and wound swabs (p = 0.001) were observed with E. faecalis. A significant correlation of enterococcal infections (p = 0.05) was seen with female patients. Four (2.9%) strains of E. faecalis found to be VRE with vanB (75%) and vanA (25%) genotypes. Conclusion: The emerging strains of VRE (vanB and vanA genotype) in the current study are a potential menace for therapeutic failure, which left the physicians with only linezolid as a therapeutic option.

Abstract
BACKGROUND The use of carbapenem antibiotics in the treatment of serious Gram-negative bacterial infections is under threat due to the emergence of the blaIMP gene amongst the bacterial pathogens. METHODS The present descriptive cross-sectional study aimed to determine the occurrence of the blaIMP gene and minimum inhibitory concentrations (MICs) of the bacterial pathogens. The carbapenem-resistant isolates were screened out for the detection of MBLs by using the modified Hodge test and disk potentiation method. MBL producing strains were tested for the presence of the blaIMP gene by using PCR technique. The MICs of the blaIMP gene positive bacterial isolates were detected on the Vitek 2 system (bioMerieux). RESULTS The primary source of MBLs and blaIPM gene carrying bacterial pathogens was blood (38.5%). We isolated 104 bacterial isolates in the initial screening of carbapenem resistance. Metallo-beta-lactamases (MBLs) were detected in 76 (73%) of the isolates which predominantly included 27 (26%) Klebsiella pneumoniae, 20 (19.2%) Acinetobacter baumannii, 16 (15.4%) Pseudomonas aeruginosa, and 11 (10.6%) E. coli while the other Gram-nega-tive MBL producing bacteria were few in number. The blaIPM gene was detected in 1 (1.3%) case of Acinetobacter baumannii and 1 (1.3%) case of Stenotrophomonas maltophilia. These strains were found to be multi-drug resistant with high MICs (≥ 8 to ≥ 256 µg/mL) against the majority of the drugs. CONCLUSIONS The emergence of the blaIPM gene is a matter of serious concern as it left us with limited treatment options of minocycline, tigecycline, and levofloxacin. The horizontal transfer of blaIPM gene in other Gram-negative isolates can lead the epidemics of multidrug resistance.

Abstract
OBJECTIVE To evaluate the occurrence and in vitro minimum inhibitory concentrations of different Candida species against nine antifungal agents in blood and urine. METHODS The prospective descriptive study was conducted at The Children's Hospital, Lahore, Pakistan, from June 2015 to May 2016. Identification of the Candid aspecies was done by API (Analytical Profile Index) Candida (bioMerieux) and in vitro minimum inhibitory concentration break points were reported by using Sensititre Yeast One. Data was analysed using SPSS 20. RESULTS Of the 87 samples, 68(78.2%) were isolated from blood and 19(21.8%) from urine specimens. Also, 66 (75.9%) samples were non-albicans Candida, 31(35.6%) Candida parapsilosis and 21(24.1%) were Candida albicans. Besides, 83(95.4%) strains exhibited excellent susceptibility pattern with the three echinocandins at minimum inhibitory concentration endpoint of ≤2μg/ml and all (100%) the strains inhibited by ≤1μg/ml of voriconazole. None (0%) of the C. albicans isolates was resistant to an antifungal agent. CONCLUSIONS Excellent susceptibility pattern against antifungal agents was found with an increasing resistance trend towards non-albicans Candida species.

Abstract
Klebsiella pneumoniae is a major threat to public health with the emergence of isolates resistant to most, if not all, useful antibiotics. We present an in-depth analysis of 178 extended-spectrum beta-lactamase (ESBL)-producing K. pneumoniae collected from patients resident in a region of Pakistan, during the period 2010–2012, when the now globally-distributed carbapenemase bla-NDM-1 was being acquired by Klebsiella. We observed two dominant lineages, but neither the overall resistance profile nor virulence-associated factors, explain their evolutionary success. Phenotypic analysis of resistance shows few differences between the acquisition of resistance genes and the phenotypic resistance profile, including beta-lactam antibiotics that were used to treat ESBL-positive strains. Resistance against these drugs could be explained by inhibitor-resistant beta-lactamase enzymes, carbapenemases or ampC type beta-lactamases, at least one of which was detected in most, but not all relevant strains analysed. Complete genomes for six selected strains are reported, these provide detailed insights into the mobile elements present in these isolates during the initial spread of NDM-1. The unexplained success of some lineages within this pool of highly resistant strains, and the discontinuity between phenotypic resistance and genotype at the macro level, indicate that intrinsic mechanisms contribute to competitive advantage and/or resistance.
