RESUMEN
Hypoplastic asymmetry due to hemifacial microsomia (HFM) often represents the most difficult reconstruction in the craniomaxillofacial clinic. Although autogenous grafts are generally used for temporomandibular joint reconstruction (TMJR), the use of TMJR prostheses is not well established. The aim of this review was to identify, collect and analyse the use of extended TMJR (eTMJR) prostheses in patients with HFM, describing clinical features, surgical procedures and postoperative complications. Online searches of all major databases were performed according to PRISMA guidelines. All studies with HFM patients treated with the eTMJR prostheses were included. Descriptive statistics were used for data analysis. A total of 19 studies, including 08 case studies, 06 case series and 05 retrospective cohort studies, met the inclusion criteria, where a total of 42 HFM patients were reported from 18 countries, mostly from the United States (05; 26%). Fifteen of the 42 cases (~36%) were male. The mean ± SD (range) age of patients in all studies was 19.79 ± 5.81 (9-36) years. The mean ± SD (range) of patient follow-up was 41.30 ± 35.50 (6-136) months. A total of 5 (10.6%) patients were implanted with bilateral eTMJR prostheses. The Pruzansky classification was used in 18 (~89.5%) studies, OMENS classification in 01 (~5%) study, whereas no classification was reported in one study. Only 01 (7.1%) study had documented the eTMJR classification for the prosthesis used. In growing patients with or without a history of failed autogenous tissues, TMJR prostheses may provide a viable alternative. Randomized studies with large cohorts are warranted to validate these preliminary results.

BACKGROUND: Transfer of all severe TBI patients to a neurosurgical unit (NSU) has been advocated irrespective of levels of complexity and prognostic factors. Previous publications have suggested that only 50% of severe TBI patients in Ireland were managed in NSUs. AIMS: This study aims to audit severe TBI referrals to the National Neurosurgical Centre, to evaluate reasons for nonacceptance, assess for differences in the transferred and not transferred cohorts and to analyse observed and expected mortality rates. METHODS: Data on all patients with TBI referred in 2021 were prospectively collected using an electronic referral system. Patients with severe TBI (GCS ≤ 8 and AIS ≥ 3) were included and dichotomised into transferred and not transferred cohorts. RESULTS: Of 118 patients referred with severe TBI, 45 patients (38.1%) were transferred to the neurosurgical centre. Patients in the transferred cohort were significantly younger (p < 0.001), had a higher GCS score (p < 0.001) and a lower proportion of bilaterally unreactive pupils (p < 0.001) compared to the not transferred cohort. 93% (68/73) of those not transferred were either >65 years old, or had bilaterally unreactive pupils, or both. Based on the IMPACT model, the observed to expected mortality ratios in the transferred and not transferred cohorts were 0.65 (95% CI 0.25-1.05) and 0.88 (95% CI 0.65-1.11) respectively. CONCLUSION: The observed mortality rate for severe TBI in Ireland was similar to or better than expected mortality rates when adjusted for important prognostic factors. 93% of severe TBI patients not transferred to a neurosurgical centre were either elderly or had bilaterally unreactive pupils or both. These patients have an extremely poor prognosis and recommendation for transfer cannot be made based on current available evidence.

Panic attacks (PAs) are prevalent and highly comorbid with various physical and psychological disorders. Cognitive-behavioral therapy (CBT) is a well-established psychosocial intervention. Internet-delivered CBT (ICBT) presents a promising avenue to overcome barriers and provide evidence-based support to those in need. The current scoping review aimed to systematically map the existing literature and identify knowledge gaps regarding the impact of ICBT on outcome measures for individuals experiencing PAs. The PRISMA guidelines for scoping reviews were used. A total of 3,044 records were retrieved, and 18 studies from 2013 to 2023 were ultimately included in the analysis. ICBT demonstrated effectiveness as a psychosocial intervention for improving panic symptoms and anxiety in individuals with PAs. However, the impact of ICBT on quality of life (QOL) remains inconclusive. All studies included in this review focused on assessing the severity of panic symptoms, with limited emphasis on measuring QOL. This scoping review holds significant implications for research and practice. However, further addressing the research needs identified in this review will enhance our understanding and improve treatment outcomes for PAs.

Clostridioides difficile infection (CDI) is a life-threatening disease caused by the Gram-positive, opportunistic intestinal pathogen C. difficile. Despite the availability of antimicrobial drugs to treat CDI, such as vancomycin, metronidazole, and fidaxomicin, recurrence of infection remains a significant clinical challenge. The use of live commensal microorganisms, or probiotics, is one of the most investigated non-antibiotic therapeutic options to balance gastrointestinal (GI) microbiota and subsequently tackle dysbiosis. In this review, we will discuss major commensal probiotic strains that have the potential to prevent and/or treat CDI and its recurrence, reassess the efficacy of probiotics supplementation as a CDI intervention, delve into lessons learned from probiotic modulation of the immune system, explore avenues like genome-scale metabolic network reconstructions, genome sequencing, and multi-omics to identify novel strains and understand their functionality, and discuss the current regulatory framework, challenges, and future directions.

The perceived risk of transmission of aerosolised viral particles from patients to airway practitioners during the COVID-19 pandemic led to the widespread use of aerosol precautions, including personal protective equipment and modifications to anaesthetic technique. The risk of these aerosol precautions on peri-operative airway complications has not been assessed outside of simulation studies. This prospective, national, multicentre cohort study aimed to quantify this risk. Adult patients undergoing general anaesthesia for elective or emergency procedures over a 96-hour period were included. Data collected included use of aerosol precautions by the airway practitioner, airway complications and potential confounding variables. Mixed-effects logistic regression was used to assess the risk of individual aerosol precautions on overall and specific airway complications. Data from 5905 patients from 70 hospital sites were included. The rate of airway complications was 10.0% (95%CI 9.2-10.8%). Use of filtering facepiece class 2 or class 3 respirators was associated with an increased risk of airway complications (odds ratio 1.38, 95%CI 1.04-1.83), predominantly due to an association with difficult facemask ventilation (odds ratio 1.68, 95%CI 1.09-2.61) and desaturation on pulse oximetry (odds ratio 2.39, 95%CI 1.26-4.54). Use of goggles, powered air-purifying respirators, long-sleeved gowns, double gloves and videolaryngoscopy were not associated with any alteration in the risk of airway complications. Overall, the use of filtering facepiece class 2 or class 3 respirators was associated with an increased risk of airway complications, but most aerosol precautions used during the COVID-19 pandemic were not.

BACKGROUND AND OBJECTIVES: Missed opportunity (MO) for IPTp SP remains high in Nigeria even among pregnant women with four or more ANC visits. We assessed the current MO rate and its predictors, using data from the 2021 MIS. METHODS: We carried out a secondary analysis of data of women who had at least one live birth and at least 4 ANC visits. Bivariate analyses assessed the relationship between socio-demographic characteristics, type of ANC facility, type of ANC provider, knowledge of malaria prevention, awareness about IPT, and missed opportunity using the Chi-square test. Multivariate analyses were presented as odd ratios at 95% CI, (P value <0.05). RESULTS: Nearly half (47%) had only primary education or none at all. About 30% were poor. Most had their 1st visit ANC in the 2nd trimester (58%). The missed opportunity rate was 55%. Predictors included age 20 to 34 years [aOR 1.3(1.1-1.67)], being very poor [aOR 1.6(1.1-2.4)], late ANC (in 2nd or 3rd trimester) [aOR 0.57(0.4-0.89)], ignorance about malaria prevention [aOR 1.8(1.4-2.4)], ignorance about IPT [aOR 1.3(1.3-2.5)] and residence in the South South and North East [aOR 0.46(0.31-0.68)] regions. CONCLUSIONS: The missed opportunity was high. Place of residence, poor knowledge of malaria prevention and IPT use, late commencement of ANC, poverty, and young age (20 to 34 years) contributed to the burden. Recommendations include stressing the importance of IPT during health talks. Provision of cups and drinking water for the IPT DOT policy by the Government and partners. There is a need for further research to unravel the reasons for the higher MO rates in some regions.
CONTEXTE: Les opportunités manquées (OM) pour le TPIp SP restent élevées au Nigéria, même parmi les femmes enceintes ayant effectué quatre visites ou plus aux soins prénatals. Nous avons évalué le taux actuel d'OM et ses prédicteurs en utilisant les données de l'Enquête sur les Indicateurs du Paludisme de 2021. MÉTHODE: Nous avons réalisé une analyse secondaire des données des femmes ayant eu au moins une naissance en vie et au moins quatre visites de soins prénatals. Les analyses bivariées ont évalué la relation entre les caractéristiques sociodémographiques, le type d'installation de soins prénatals, le type de prestataire de soins prénatals, la connaissance de la prévention du paludisme, la sensibilisation à propos du TPIp, et les opportunités manquées en utilisant le test du chi-carré. Les analyses multivariées ont été présentées sous forme de cotes ajustées avec un intervalle de confiance de 95 % (valeur de p<0,05). RÉSULTATS: Près de la moitié (47 %) avaient seulement une éducation primaire ou n'en avaient pas du tout. Environ 30 % étaient pauvres. La plupart ont effectué leur 1ère visite prénatale au cours du 2ème trimestre (58 %). Le taux d'opportunités manquées était de 55 %. Les prédicteurs comprenaient l'âge de 20 à 34 ans [aOR 1,3 (1,1-1,67)], être très pauvre [aOR 1,6 (1,1-2,4)], début tardif des soins prénatals (au 2ème ou 3ème trimestre) [aOR 0,57 (0,4-0,89)], ignorance de la prévention du paludisme [aOR 1,8 (1,4-2,4)], ignorance du TPIp [aOR 1,3 (1,3-2,5)] et résider dans les régions du Sud-Sud et du Nord-Est [aOR 0,46 (0,31-0,68)]. CONCLUSION: Les opportunités manquées étaient élevées. Le lieu de résidence, la méconnaissance de la prévention du paludisme et de l'utilisation du TPIp, le début tardif des soins prénatals, la pauvreté et l'âge jeune (20 à 34 ans) ont contribué à cette charge. Les recommandations incluent de souligner l'importance du TPIp lors des entretiens de santé. La fourniture de gobelets et d'eau potable pour la politique de l'administration directe du TPI par le gouvernement et les partenaires. Il est nécessaire de poursuivre la recherche pour découvrir les raisons des taux plus élevés d'OM dans certaines régions.

BACKGROUND: Tracheostomy can be performed as an open surgical procedure, percutaneous, or hybrid and forms an important step in the management of patients infected with coronavirus disease 2019 (COVID-19) requiring weaning from mechanical ventilation. The purpose of this article is to share our experience to performing bedside surgical tracheostomy in COVID-19 patients in a safe and effective manner, whilst minimising the risk of viral transmission, to optimise patient outcomes and reduce risk to healthcare professionals. MATERIAL AND METHODS: As recommended by ENT UK, we prospectively established a COVID Airway Team within the ENT department at Birmingham Heartlands Hospital, consisting of four head and neck consultant surgeons to perform either open-bedside, open-theatre or percutaneous tracheostomy in COVID-19 patients. A specific stepwise method for bedside open surgical tracheostomy was based on ENT UK and British Laryngological Society recommendations. RESULTS: Thirty patients underwent tracheostomy during the study period (14 bedside-open, 5 open-theatre, 11 percutaneous). Mean duration of mechanical intubation prior to bedside-open tracheostomy was 14.5 days. The average time for open-bedside tracheostomy was 9 minutes compared to 31 minutes for open-theatre. There were no significant tracheostomy related complications with bedside-open tracheostomy. No healthcare professional involved reported acute COVID-19 infection. CONCLUSIONS: We describe our effective, safe and swift approach to bedside open tracheostomy during the COVID-19 pandemic. Our experience demonstrated a short mean procedural time, with no tracheostomy-related complications and no reported viral transmission amongst the healthcare members involved.
RESUMEN
INTRODUCTION: Repeat abdominal surgery in the bariatric surgery patient population may be challenging for non-bariatric-accredited institutions. The impact of regionalized bariatric care on clinical outcomes for bariatric surgery patients requiring repeat abdominal surgery is currently unknown. This study aims to investigate the association between bariatric center designation and clinical outcomes following hepatobiliary, hernia, and upper and lower gastrointestinal operations among patients with prior bariatric surgery. METHODS: This is a cohort study of a large sample of Ontario residents who underwent primary bariatric surgery between 2010 and 2017. A comprehensive list of eligible abdominal operations was captured using administrative data. The primary outcome was 30-d complications. Secondary outcomes included 30-d mortality, readmission, and length of stay. RESULTS: Among the 3301 study patients, 1305 (40%) received their first abdominal reoperation following bariatric surgery at a designated bariatric center. Nonbariatric center designation was not associated with significantly higher rates of 30-d complications (5.73% versus 5.72%), mortality (0.80% versus 0.77%), readmissions (1.11% versus 1.85%), or median postoperative length of stay (4 versus 4 d). After grouping the category of reoperations, upper gastrointestinal (odds ratio [OR] 0.66, confidence interval [CI] 0.39-1.11) and abdominal wall hernia surgery (OR 0.52, CI 0.27-0.99) showed a lower adjusted OR for complications among bariatric centers. CONCLUSIONS: Our study demonstrates that after adjustment for case-mix and patient characteristics, bariatric surgery patients undergoing repeat abdominal surgery at nonbariatric centers is not associated with higher proportion of complications or mortality. Complex hernia surgery may be considered the most appropriate for referral.

PURPOSE: To assess the safety and efficacy of the posthemostasis use of an inflatable adhesive external compression device (SafeGuard) following angiography in children performed under general anesthesia. MATERIALS AND METHODS: Medical records of 74 children (43 females) with a mean age of 8.9 years (range, 0.4-18.0 years) and mean weight of 44.0 kg (range, 7.3-115.7 kg) in whom an inflatable adhesive external compression device was used for maintaining hemostasis following angiography under general anesthesia were retrospectively reviewed. After establishing hemostasis with manual compression, the device was applied and inflated over the arteriotomy. The patients were assessed for access-related adverse events in the recovery unit and during postprocedural follow-up. RESULTS: The inflatable adhesive external compression device was utilized to maintain hemostasis following 181 angiography procedures. The mean length of the procedure was 396 minutes. The common femoral artery (n = 170, 93.9%) was the most common access, using 4-5-F vascular sheath (n = 118, 65.2%) or 3-5-F sheathless (n = 8, 12.7%) catheters. The mean time to deflation was 93 minutes. There were no adverse events other than minor bleeding from the arteriotomy after deflation (n = 2, 1.1%) and early deflation of the device because of pain (n = 1, <1%). Follow-up ultrasonography (n = 109 procedures, 60.2% at a mean follow-up of 2.2 years) demonstrated patency of the access artery. CONCLUSIONS: The use of an inflatable adhesive external compression device following angiography in children to maintain hemostasis during the emergence phase of anesthesia and recovery period is safe and effective. The use of this simple device may reduce the need for postprocedural sedation and facilitate early discharge.

BACKGROUND: Colonoscopy is a technically challenging procedure. The colonoscope is prone to forming loops in the colon, which can lead patient discomfort and even perforation. We hypothesized that expert endoscopists use techniques to avoid loop formation, identify and straighten loops earlier, and thus exert less force. METHODS: Using a commercially available physical colon simulator model (Kyoto Kagaku), electromagnetic tracking markers (NDI Medical) were placed along the mobile segments of the colon (sigmoid, transverse) to measure the degree of displacement of the colon as the scope was advanced to the cecum. The colon model was set for each participant to simulate a redundant alpha loop in the sigmoid colon. Gastroenterology and surgical trainees and attendings were assessed. Demographic data were collected for each participant. RESULTS: Seventy-five participants were enrolled in the study. There were 17 (22.7%) attending physicians, and 58 (77.3%) trainees. Attending physicians advanced the scope to the cecum faster. The mean time required for procedure completion was 360.5 s compared to 178.4 s for the trainee and attending groups respectively (mean difference: 182.1 s, 95% CI: 93.0, 269.7; p = 0.0002). Attending physicians exerted significantly lower mean colonic displacement than trainees. The mean colonic displacement was 79.8 mm for the trainee group and 57.9 mm for the attending group (mean difference: 21.9 mm, 95% CI: 2.6, 41.2; p = 0.04). Those who used torque steering caused lower maximum colonic displacement than those who used knob steering. CONCLUSION: Attending physicians advance the scope during colonoscopy in a manner that results in significantly less colonic displacement than resident trainees. Although prior studies have shown a difference in force application between endoscopists and inexperienced students, ours is the first to differentiate across varying degrees of endoscopic skill. Future studies will define metrics for incorporation into endoscopic training curricula, focusing on techniques that encourage safety and comfort for patients.

BACKGROUND: Routine computed tomography (CT) scans are thought to have poor performance for detection of gastrointestinal (GI) neuroendocrine neoplasms (NENs), which leads to delayed workup. Detection of even 1 bowel tumor can guide diagnostic workup and management. The purposes of this study were to assess the accuracy of multidetector computed tomography (MDCT) and to compare negative versus positive enteric contrast in detecting at least 1 GI tumor per patient with suspected or confirmed diagnosis of a NEN. METHODS: This retrospective study included 107 patients with intravenous and oral contrast (65 positive, 40 negative, and 2 no oral contrast) abdominopelvic MDCT. Two abdominal radiologists independently analyzed the CTs for detection and localization of bowel NENs. Surgical pathology was considered the reference standard. Analyses included κ and summary statistics, McNemar test, Pearson χ2 test, and Fisher exact test. RESULTS: Among the 107 CT scans, there were 30 pathology negative studies and 77 studies with positive pathology for GI NEN. Interreader agreement for CT evaluation was substantial (κ = 0.61). At least 1 GI NEN per patient was detected with 51% to 53% sensitivity, 87% to 93% specificity, 91% to 95% positive predictive value (PPV), 42% negative predictive value, and 63% accuracy for each reader, and 57% accuracy when only the concordant (ie, matching) results of the 2 readers were considered. Computed tomography scans with negative enteric contrast had significantly higher sensitivity for concordant results than CTs with positive enteric contrast (58% vs 30%, P = 0.01). Specificity (100% vs 95%, P = 0.5), PPV (100% vs 93%, P = 0.49), negative predictive value (39% vs 39%, P = 0.99), and accuracy (67% vs 51%, P = 0.10) were not significantly different for negative versus positive enteric contrast for the concordant results. There was no significant difference in GI NEN localization between the readers. CONCLUSIONS: Routine MDCT with either positive or negative enteric contrast can detect at least 1 GI tumor per patient with more than 90% PPV and more than 50% accuracy in patients suspected of GI NEN. Using negative enteric contrast improves sensitivity for GI NEN versus positive enteric contrast. In addition, there is high accuracy in localizing the bowel tumor with positive or negative enteric contrast, which may guide surgery. Radiologists should have heightened awareness that evaluating such scans closely may lead to detection of primary bowel NENs at a higher rate than previously reported.

Difficult airway management continues to adversely affect patient care and clinical outcomes and is poorly predicted. Previous difficult airway management is the most accurate predictor of future difficulty. The Difficult Airway Society initiated a national airway database to allow clinicians to access details of previous difficult airway episodes in patients issued with a difficult airway alert card. We aimed to analyse this database, reporting patient characteristics, airway management and patient outcomes. We included all living adult patients reported in the first 5 years of the database (n = 675). Clinical airway assessment was reported in 634 (94%) patients, with three or more parameters assessed in 488 (72%). A history of difficult airway was known in 136 (20%) patients and difficult airway management was anticipated in 391 (58%). In all, 75 (11%) patients had an airway-related critical incident, with 1 in 29 being awoken from anaesthesia, 1 in 34 requiring unplanned or prolonged stay in the intensive care unit and 1 in 225 needing an emergency front-of-neck airway or had a cardiac arrest/peri-arrest episode. Airway-related critical incidents were associated with out-of-hours airway management, but no other associations were apparent. Our data report the first analysis of a national difficult airway database, finding that unanticipated difficult airway management continues to occur despite airway assessment, and the rate of critical incidents in this cohort of patients is high. This database has the potential to improve airway management for patients in the future.

Haematoma after thyroid surgery can lead to airway obstruction and death. We therefore developed guidelines to improve the safety of peri-operative care of patients undergoing thyroid surgery. We conducted a systematic review to inform recommendations, with expert consensus used in the absence of high-quality evidence, and a Delphi study was used to ratify recommendations. We highlight the importance of multidisciplinary team management and make recommendations in key areas including: monitoring; recognition; post-thyroid surgery emergency box; management of suspected haematoma following thyroid surgery; cognitive aids; post-haematoma evacuation care; day-case thyroid surgery; training; consent and pre-operative communication; postoperative communication; and institutional policies. The guidelines support a multidisciplinary approach to the management of suspected haematoma following thyroid surgery through oxygenation and evaluation; haematoma evacuation; and tracheal intubation. They have been produced with materials to support implementation. While these guidelines are specific to thyroid surgery, the principles may apply to other forms of neck surgery. These guidelines and recommendations provided are the first in this area and it is hoped they will support multidisciplinary team working, improving care and outcomes for patients having thyroid surgery.

BACKGROUND: In the light of recent years, an increase in the number of life-threatening infections due to various fungi has been observed, especially in tertiary care centres. With Amphotericin B labelled as the first choice in treating these infections, one of its common side effects, nephrotoxicity, along with hypokalemia, were studied to determine the epidemiology, risk factors, and protective measures. METHODOLOGY: The study was a retrospective observational chart review study in which patients were receiving conventional Amphotericin B in two tertiary hospitals in Palestine from January 2018 to December 2020 were evaluated for the development of hypokalemia and nephrotoxicity; according to the KDIGO criteria. A total of 117 patients were included in the study. Patients who have received the drug intermittently, in fewer than two doses, through non-IV routes and patients under the age of 12 were excluded. The data collected included, but were not limited to, age, gender, comorbidities, Amphotericin B treatment details, medications, COVID-19 status, risk factors, and hypothesized protective measures. RESULTS: The incidence of conventional Amphotericin B nephrotoxicity and hypokalemia was 46% and 33%, respectively. With a roughly equal representation of both genders and a median age of 52 years in a range of 13-89. No association between the variables and the development of nephrotoxicity was found. However, a 3.4 increased risk (p-value = 0.01) of developing hypokalemia in females compared to males was observed. CONCLUSION: Our research has shown a relatively lower yet consistent, incidence of conventional amphotericin B nephrotoxicity and hypokalemia compared to literature with gender being a risk factor for developing hypokalemia.

Water scarcity is not a novel issue. It has already affected almost every continent in this blue planet. It is driven by two primary sources: increasing demand for fresh water due to the increase in population and overexhaustion of the available freshwater resources. During the past decade, stress has been given to extract fresh, clean and safe potable elixir of life from the bountiful stores of sea water by exploiting various technologies. As nanomaterials are providing promising solutions to almost all our problems, they are again being accessed in order to combat the problem of global freshwater scarcity. Desalination methods have marvellously improved under the impact of nanomaterials. Different metallic nanomaterials are being used to serve this purpose; for example, silver, iron, zinc, titanium dioxide in addition to natural and synthetically derived polymeric bionanomaterials. In the present paper, a brief account of all the metallic nanomaterials which are being used for treatment of water has been provided by thorough investigation on the research done till now. It strives to throw light on various materials and methods which are based on the exploitation of nanotechnology for the treatment of water.

BACKGROUND: Same-day surgery is an increasingly utilized and cost-effective strategy to manage common surgical conditions. However, many institutions limit ambulatory surgical services to only healthy individuals. There is also a paucity of data on the safety of same-day discharge among high-risk patients. This study aims to determine whether same-day discharge is associated with higher major morbidity and readmission rates compared with overnight stay in high-risk general surgery patients. METHODS: This is a retrospective cohort using the data from the National Surgical Quality Improvement Program from 2005 to 2017. Patients with an American Society of Anesthesiologists class ≥3 undergoing general surgical procedures amenable to same-day discharge were identified. Primary and secondary outcomes were major morbidity and readmission at 30 d. A multivariable logistic regression model using mixed effects was used to adjust for the effect of same-day discharge. RESULTS: Of 191,050 cases, 137,175 patients (72%) were discharged on the same day. At 30 d, major morbidity was 1.0%, readmission 2.2%, and mortality <0.1%. Adjusted odds ratio of same-day discharge was 0.59 (95% confidence interval 0.54-0.64; P < 0.001) for major morbidity and 0.75 (95% confidence interval 0.71-0.80; P < 0.001) for readmission. Significant risk factors for morbidity and readmission included nonindependent functional status, ascites, renal failure, and disseminated cancer. CONCLUSIONS: Major morbidity and readmission rates are low among this large sample of high-risk general surgery patients undergoing common ambulatory procedures. Same-day discharge was not associated with increased adverse events and could be considered in most high-risk patients after uncomplicated surgery.

In this work, synthesis of graphene oxide (GO) and reduced graphene oxide (rGO) was realized through a modified Hummers route. Different concentrations (5 and 10 wt%) of Ag were doped in MoS2and rGO using a hydrothermal technique. Synthesized Ag-MoS2and Ag-rGO were evaluated through XRD that confirmed the hexagonal structure of MoS2along with the transformation of GO to Ag-rGO as indicated by a shift in XRD peaks while Mo-O bonding and S=O functional groups were confirmed with FTIR. Morphological information of GO and formation of MoS2nanopetals as well as interlayer spacing were verified through FESEM and HRTEM respectively. Raman analysis was employed to probe any evidence regarding defect densities of GO. Optical properties of GO, MoS2, Ag-rGO, and Ag-MoS2were visualized through UV-vis and PL spectroscopy. Prepared products were employed as nanocatalysts to purify industrial wastewater. Experimental results revealed that Ag-rGO and Ag-MoS2showed 99% and 80% response in photocatalytic activity. Besides, the nanocatalyst (Ag-MoS2and Ag-rGO) exhibited 6.05 mm inhibition zones againstS. aureusgram positive (G+) and 3.05 mm forE. coligram negative (G-) in antibacterial activity. To rationalize biocidal mechanism of Ag-doped MoS2NPs and Ag-rGO,in silicomolecular docking study was employed for two enzymes i.e.ß-lactamase and D-alanine-D-alanine ligase B (ddlB) from cell wall biosynthetic pathway and enoyl-[acylcarrier-protein] reductase (FabI) from fatty acid biosynthetic pathway belonging toS. aureus. The present study provides evidence for the development of cost-effective, environment friendly and viable candidate for photocatalytic and antimicrobial applications.

AIMS: This study was designed to analyse the prevalence of class 1 and class 2 integron integrase genes among antibiotic-resistant coliform bacteria isolated from paper currency circulating in Pakistan. METHODS AND RESULTS: A total of 500 individual currency notes were collected from different food vending sites at Lahore, Pakistan. Bacterial population were identified by biochemical and PCR techniques. Antimicrobial susceptibility testing was performed by disc diffusion assay. The highest bacterial population on currency was found from street vendors and butcher shops. Escherichia coli was found to be the most prevalent coliform bacteria followed by Klebsiella sp. and Enterobacter sp. PCR amplification of antimicrobial resistance gene showed the presence of ampC, blaTEM , blaNDM-1 , qnrA, tet(A) and tet(B) genes among coliform isolates. A total of 47 integron integrase bearing strains of coliform bacteria were analysed. Sequence analysis showed the presence of dfrA1-aadA1, dfrA1, dfrA5, dfrA7, aadA1, aadA4 cassette arrays in class 1 integron and dfrA1-sat2-aadA1 in class 2 integrase genes. CONCLUSION: Circulating currency was heavily contaminated with antimicrobial-resistant coliform bacteria bearing class 1 and class 2 integron integrase genes. SIGNIFICANCE AND IMPACT OF THE STUDY: This study describes a potential threat of severe bacterial infections due to improper hand hygiene and community sanitation when dealing with the currency notes.

AIMS: The present research aimed to examine the use of magnetite nanoparticles (MNPs) in combination with phyto-beneficial rhizobacterium (PhBR) for improvement of applied N recovery (ANR) from urea fertilizer in rice grown under deficient and optimum watering conditions. METHODS AND RESULTS: The Bacillus sp. MR-1/2 was positive for acetylene reduction, phosphate solubilization and ACC deaminase activity at temperature ranges 35-45°C. In a pot experiment, urea, MNPs and Bacillus sp. MR-1/2 were applied either alone or in combination to rice plants grown in pots under water deficit and optimal watering conditions. Combined application of urea, MNPs and Bacillus sp. MR-1/2 increased the plant N content and ANR by 27 and 65%, respectively, over their respective control values in rice grown under optimum watering conditions, whereas these increases were 27 and 41%, respectively, in rice grown under water deficit conditions. This treatment also increased the kernel weight and plant dry matter by 36 and 60%, respectively, over control (urea alone) values in rice grown under water deficit conditions, whereas these increases were 31 and 21·8%, respectively, in rice grown under optimum watering conditions. Values of malondialdehyde (MDA) contents, ascorbate peroxidase (APX), catalase and ethylene concentration were higher in control treatment under both the watering regimes. The application of Bacillus sp. MR-1/2 either alone or in combination with MNPs and urea reduced MDA contents, APX, catalase and ethylene production in the rice plants. CONCLUSION: The combined application of MNPs+Bacillus sp. MR-1/2 reduced the N losses from applied urea, increased N uptake and ANR in rice, decreased MDA contents, APX and catalase activity and ethylene level in rice grown under deficit and optimum water conditions. SIGNIFICANCE AND IMPACT OF THE STUDY: The application of MNPs together with Bacillus sp. MR-1/2 may help to increase ANR and rice productivity under water deficit conditions with low cost of production.
