Modification of physicochemical properties of chitosan to improve its pharmaceutical and agrochemical potential applications. Int J Biol Macromol 2024; 267:131404. [PMID: 38582466 DOI: 10.1016/j.ijbiomac.2024.131404] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 03/19/2024] [Accepted: 04/03/2024] [Indexed: 04/08/2024]
Abstract
Chitosan has received much more attention as a functional biopolymer with applications in pharmaceuticals, agricultural, drug delivery systems and cosmetics. The objectives of present investigation were to carry out modification of chitosan for enhancement of aqueous solubility, which will impart increased solubility and dissolution rate of poorly soluble drug itraconazole (ITZ) and also evaluate the modified chitosan for soyabean seed germination studies. The modification of chitosan was accomplished through the antisolvent precipitation method; employing five carboxylic acids. The resulting products were assessed for changes in molecular weight, degree of deacetylation, solubility and solid state characterization. Subsequently, the modified chitosan was complexed with itraconazole using the co-grinding technique. The prepared formulations were evaluated for solubility, FTIR (Fourier-transform infrared spectroscopy), PXRD (Powder X-ray diffraction), in-vitro dissolution studies. Furthermore the effect of modified chitosan has been evaluated on soybean seed germination. Results demonstrated that, modified chitosan improves self and solubility of itraconazole by six folds. As there was increased degree of deacetylation of chitosan leads to improvement in solubility. The results of FTIR showed the slight shifting of peaks in co-grind formulations of itraconazole. Formulations showed reduction in crystallinity of drug which leads to enhancement in dissolution rate as compared to pure itraconazole. Retention of property of seed germination was observed with modified chitosan at optimum concentration of 3 % w/v, with benefit of enhanced aqueous solubility of chitosan. This positive result paves the way for the advancement of pharmaceutical and agrochemical products employing derivatives of chitosan.

Abstract
BACKGROUND AND AIM Gram-negative bacteria (GNB) with potential multiple drug resistance (MDR) have emerged as a major group of organisms causing ventilator-associated pneumonia (VAP). Higher concentrations are deposited directly in the lungs when antibiotics are given via inhalation, minimizing systemic side effects. This study aims to compare the efficacy and safety of intravenous plus aerosolized colistin versus intravenous (IV) colistin alone in critically ill trauma patients who reported MDR-GNB infection on endotracheal aspirate culture. METHODS A hundred patients were recruited in the Intensive Care Unit, Trauma Centre, Institute of Medical Sciences, Banaras Hindu University, Varanasi, and randomly assigned to the control (n=50) group, which received IV colistin plus aerosolized colistin and the intervention group (n = 50), which received IV colistin alone. Changes in total leucocyte count (TLC), renal function test (RFT), endotracheal aspirate culture, 24-hour urine output, length of ICU stay, and 28-day ICU mortality were investigated. RESULTS Patients receiving intravenous plus nebulized colistin therapy had a better outcome compared to IV colistin alone in terms of faster eradication of MDR-GNB infection. A rise in serum urea and creatinine levels was seen in both groups, which were significantly higher, along with a decrease in urine output in the group receiving intravenous colistin alone. No significant difference was observed in serum sodium and potassium levels in the RFT protocol, length of ICU stay, or 28-day ICU mortality. CONCLUSION Intravenous nebulized colistin could be considered a better alternative therapy for VAP caused by multi-drug-resistant Gram-negative bacteria in the ICU in terms of faster microbiological cure and lesser nephrotoxicity.

Accuracy of Femoral Tunnel Placement between Anteromedial and Anterolateral Visualisation Portals in Anterior Cruciate Ligament Reconstruction - Outcomes of a CT based Cross-Sectional Study. Malays Orthop J 2023; 17:7-12. [PMID: 37583529 PMCID: PMC10424999 DOI: 10.5704/moj.2307.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 08/18/2022] [Indexed: 08/17/2023] Open
Abstract
Introduction Anatomical femoral tunnel placement is critical for anterior cruciate ligament reconstruction (ACLR). Tunnel placement may vary with different surgical techniques. The aim of this study was to compare the accuracy of femoral tunnel placement between the Anteromedial (AM) and Anterolateral (AL) visualisation portals on post-operative CT scans among a cohort of ACLR patients. Materials and methods This cross-sectional study was conducted from January 2018 to March 2020 after obtaining ethics clearance. Patients who went for arthroscopic ACLR in our institute were divided into an AM (group 1) and an AL (group 2) based on the visualisation portal for creating the femoral tunnel and a 3D CT scan was done. The femoral tunnel position was calculated in deep to shallow and high to low direction using the Bernard Hertel grid. Femoral tunnel angle was measured in the 2D coronal image. Statistical analysis was done with the data collected. Results Fifty patients with an average age of 26.36 (18-55) years ±7.216 SD were enrolled in the study. In this study, the AM technique was significantly more accurate (p<0.01) than the AL technique in terms of femoral tunnel angle. Furthermore, the deep to the shallow position was significantly (p= 0.018) closer to normative values, as determined by the chi-square test. The chances of error in tunnel angle in femoral condyle are 2.6 times greater in the AL technique (minimal clinical difference). Conclusion To conclude, in ACLR the anteromedial visualisation portal can facilitate accurate femoral tunnel placement compared to the anterolateral visualisation portal.

Susceptibility profile of bla OXA-23 and metallo-β-lactamases co-harbouring isolates of carbapenem resistant Acinetobacter baumannii (CRAB) against standard drugs and combinations. Front Cell Infect Microbiol 2023; 12:1068840. [PMID: 36683677 PMCID: PMC9853021 DOI: 10.3389/fcimb.2022.1068840] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 12/20/2022] [Indexed: 01/09/2023] Open
Abstract
Background The rapid emergence of carbapenem resistant Acinetobacter baumannii (CRAB) has resulted in an alarming situation worldwide. Realizing the dearth of literature on susceptibility of CRAB in genetic context in the developing region, this study was performed to determine the susceptibility profile against standard drugs/combinations and the association of in-vitro drug synergy with the prevalent molecular determinants. Methods and findings A total of 356 clinical isolates of A. baumannii were studied. Confirmation of the isolates was done by amplifying recA and ITS region genes. Susceptibility against standard drugs was tested by Kirby Bauer disc diffusion. Minimum inhibitory concentration (MIC), MIC50 and MIC90 values against imipenem, meropenem, doripenem, ampicillin/sulbactam, minocycline, amikacin, polymyxin B, colistin and tigecycline was tested as per guidelines. Genes encoding enzymes classes A (bla GES, bla IMI/NMC-A, bla SME, bla KPC), B (bla IMP, bla VIM, bla NDM) and D (bla OXA-51, bla OXA-23 and bla OXA-58) were detected by multiplex polymerase chain reaction. Synergy against meropenem-sulbactam and meropenem-colistin combinations was done by checkerboard MIC method. Correlation of drug synergy and carbapenemase encoding genes was statistically analyzed. Results Of the total, resistance above 90% was noted against gentamicin, ciprofloxacin, levofloxacin, ceftazidime, cefepime, ceftriaxone, cotrimoxazole and piperacillin/tazobactam. By MIC, resistance rates from highest to lowest was seen against imipenem 89.04% (n=317), amikacin 80.33% (n=286), meropenem 79.49% (n=283), doripenem 77.80% (n=277), ampicillin/sulbactam 71.62% (n=255), tigecycline 55.61% (n=198), minocycline 14.04% (n=50), polymyxin B 10.11% (n=36), and colistin 2.52% (n=9). CRAB was 317 (89.04%), 81.46% (n=290) were multidrug resistant and 13.48% (n=48) were extensively drug resistant. All the CRAB isolates harboured bla OXA-51 gene (100%) and 94% (n=298) bla OXA-23 gene. The bla IMP gene was most prevalent 70.03% (n=222) followed by bla NDM, 59.62% (n=189). Majority (87.69%, 278) were co-producers of classes D and B carbapenemases, bla OXA-23 with bla IMP and bla NDM being the commonest. Synergy with meropenem-sulbactam and meropenem-colistin was 47% and 57% respectively. Reduced synergy (p= <0.0001) was noted for those harbouring bla OXA-51+blaOXA-23with bla NDM gene alone or co-producers. Conclusion Presence of bla NDM gene was a significant cause of synergy loss in meropenem-sulbactam and meropenem-colistin. In bla NDM endemic regions, tigecycline, minocycline and polymyxins could be viable options against CRAB isolates with more than one carbapenemase encoding genes.

Abstract
OBJECTIVE The excessive desire to void with discomfort in the supra-pubic region, which is experienced postoperatively by patients who underwent urinary catheterization, is known as catheter-related bladder discomfort. In this study, we evaluated duloxetine, a selective serotonin and norepinephrine reuptake inhibitor, in preventing catheter-related bladder discomfort. MATERIAL AND METHODS Around 64 adults (18-60 years), of either sex, with American Society of American Society of Anesthesiologists (ASA) physical status I and II, scheduled to undergo elective gastrointestinal carcinoma surgeries under general anesthesia were analyzed in the final assessment of 2 comparative groups C and D of 32 patients each. Group D received 1 ranitidine tablet of 150 mg and 1 duloxetine tablet of 60 mg, while group C patients received 2 tablets of ranitidine of 75 mg 2 hours prior to induction. A 16 F Foley catheter was used to catheterize bladder intra-operatively, and 10 mL of distilled water was used to fill the balloon. At 0, 1, 2, and 6 hours, the catheter-related bladder discomfort was evaluated, and categorized into none, mild, moderate, and severe. The study drug's adverse effects, if any, were reported. RESULTS At all-time intervals, group D had lower incidence and severity of catheterrelated bladder discomfort than group C (P < .05). Compared to group C, patients in group D had a higher incidence of nausea, dizziness, and vomiting; nevertheless, the difference was statistically insignificant (P > .05). CONCLUSION Duloxetine of 60 mg given orally 2 hours before induction decreases the incidence and severity of catheter-related bladder discomfort.

Abstract
BACKGROUND India encountered two waves of COVID-19 pandemic with variability in its characteristics and severity. Concerns were raised over the safety of treatment, and higher morbidity was predicted for oncological surgery. The present study was conducted to evaluate and compare the rate of morbidity and mortality in patients undergoing curative surgery for cancer before and during the COVID-19 pandemic. METHOD The prospectively obtained clinical data of 1576 patients treated between April 2019 and May 2021 was reviewed; of these, 959 patients were operated before COVID-19 and 617 during the pandemic. The data on complications, deaths, confirmed or suspected COVID-19 cases, and COVID-19 infection among health workers (HCW) was extracted. RESULTS A 35% fall in number of surgeries was seen during the COVID period; significant fall was seen in genital and esophageal cancer. There was no difference in postoperative complication; however, the postoperative mortality was significantly higher. A total of 71 patients had COVID-19, of which 62 were preoperative and 9 postoperative, while 30/38 healthcare workers contracted COVID-19, of which 7 had the infection twice and 3 were infected after two doses of vaccination; there was no mortality in healthcare workers. CONCLUSION The present study demonstrates higher mortality rates after surgery in cancer patients, with no significant change in morbidity rates. A substantial proportion of HCWs were also infected though there was no mortality among this group. The results suggest higher mortality in cancer patients despite following the guidelines and protocols.

Abstract
Introduction Firesetting is a behavior, arson is a crime, and pyromania is a psychiatric diagnosis. Arson is a criminal act in which a person or group of persons willing fully and maliciously sets fire or aid in firesetting to cause harm to property, people, and infrastructure. The likelihood of an arson offender having schizophrenia is 20 times greater than that in the general population. Here, we describe the case of a male in his 50’s, a first-time arsonist, who suffered from schizophrenia since his late teens prior to the onset of random firesetting behavior. Objectives To understand the association between Arson and Schizophrenia. Methods A case report, as well as a review of the literature, was conducted. Results The patient is a male in his 50’s carrying a diagnosis of Schizophrenia with over 50 inpatient hospitalizations. He was observed standing on the threshold of a neighbor’s apartments where he allegedly set fire to a pile of clothing. These charges are based upon allegations that he attempted to set fire to a 14-storey apartment building. At the time of his assessment, he was floridly psychotic. He was found not fit to stand trial. He was restarted on Clozapine and Depakote which is the medication he had the most success with. Conclusions Literature shows that Arson and firesetting behaviors are quite commonly seen in patients with mental disorders. Arson often has sequelae that negatively impact the community. The strong correlation between firesetting behavior and mental disorders needs extensive, detailed collaboration between psychiatry, legal expertise, and fire services. Disclosure No significant relationships.

Abstract
Introduction: Venipuncture is often a painful procedure causing significant anxiety, distress, and psychological consequences. We evaluated the efficacy of estradiol cream and compared it with a eutectic mixture of local anesthetics (EMLA) cream for alleviation of venipuncture pain and to make cannulation easy in female obese patients. Materials and methods: The clearance from the Institutional Ethical Committee as well as prior written and informed consent were obtained from the participants. A total of 105 obese female adult patients aged between 25 and 64 years belonging to the American Society of Anesthesiologists (ASA) physical status I and II with body mass index (BMI) > 30 kg/m2 were included in our study. The study participants were randomly allocated into three groups: In group I, a placebo cream was applied; in group II, estradiol cream was applied, and in group III, EMLA cream was applied. Any abnormal sensation at the site of application of the cream was noted and followed up at 0, 2, and 6 hours for the same. The primary outcome was the measurement of the severity of the pain experienced during venipuncture using the visual analog scale (VAS). Ease of cannulation was our secondary outcome. VAS was compared with the Z test. Statistical Package for the Social Sciences (SPSS) v16.0 software (SPSS Inc., Chicago) was used for statistical analysis. A p-value of <0.05 was considered statistically significant. Result: The final analysis was carried out on 25 patients in group I, 27 patients in group II, and 33 patients in group III. There was no significant improvement in the ease of cannulation in group II when compared to group I. The mean VAS was similar in group I and group II, whereas it was significantly reduced in group III (p < 0.05). Conclusion: EMLA cream was found to significantly reduce the pain of venipuncture in comparison to placebo and estradiol cream. There is no beneficial effect of estradiol cream in reducing the pain from venipuncture or in ease of cannulation compared to placebo.

Abstract
In the wake of the COVID-19 pandemic, digital health tools have been deployed by governments around the world to advance clinical and population health objectives. Few interventions have been successful or have achieved sustainability or scale. In India, government agencies are proposing sweeping changes to India's digital health architecture. Underpinning these initiatives is the assumption that mobile health solutions will find near universal acceptance and uptake, though the observed reticence of clinicians to use electronic health records suggests otherwise. In this practice article, we describe our experience with implementing a digital surveillance tool at a large mass gathering, attended by nearly 30 million people. Deployed with limited resources and in a dynamic chaotic setting, the adherence to human-centered design principles resulted in near universal adoption and high end-user satisfaction. Through this use case, we share generalizable lessons in the importance of contextual relevance, stakeholder participation, customizability, and rapid iteration, while designing digital health tools for individuals or populations.

Abstract
BACKGROUND Extensive drug resistance in Klebsiella pneumoniae (K. pneumoniae) causing major outbreaks in large hospitals is an emerging challenge. We describe a near fatal outbreak of colistin resistant, carbapenem resistant K. pneumoniae (CRKp) producing metallo beta-lactamases (blaNDM) and blaOXA-48 in the neonatal intensive care unit (NICU) at the background of a larger outbreak involving multiple parts of the hospital and the challenges in its containment. METHODS Following identification of an outbreak due to colistin resistant CRKp between April to June 2017 in the NICU, a thorough surveillance of similar cases and the hospital environment was performed to trace the source. All the isolated K. pneumoniae were tested for susceptibility to standard antibiotics by disc diffusion and microbroth dilution methods. Molecular detection of extended spectrum beta lactamases (ESBLs) and carbapenemases (classes A, B, D) genes was done. Enterobacterial repetitive intergenic consensus (ERIC) PCR and multi-locus sequence typing (MLST) was done to determine the genetic relatedness of the isolates. Characteristics of different sequence types were statistically compared (Student's t-test). RESULTS A total of 45 K. pneumoniae isolates were studied from NICU (14 cases of neonatal sepsis), ICU (18 cases), other wards (7 cases) along with 6 isolates from hospital environment and human colonizers. The primary case was identified in the ICU. All the K. pneumoniae from NICU and 94.4% from the ICU were colistin resistant CRKp. Majority (59.37% and 56.25%) harbored blaSHV/blaCTXM and blaOXA-48 genes, respectively. Two distinct sequence types ST5235 and ST5313 were noted with colistin resistance, distribution within the NICU and mortality as significant attributes of ST5235 (p < 0.05). The outbreak was contained with strengthening of the infection control practices and unintended short duration closure of the hospital. CONCLUSION Large hospital outbreaks with considerable mortality can be caused by non-dominant clones of colistin resistant CRKp harboring blaOXA-48 and blaNDM carbapenemases in endemic regions. The exact global impact of these sequence types should be further studied to prevent future fatal outbreaks.

Abstract
Introduction: Chlorpromazine belongs to the category of typical antipsychotics or neuroleptics, also known as FirstGeneration Antipsychotics (FGAs). It is found to be effective in hiccup management by its action as dopamine antagonist in the hypothalamus. Olanzapine act as an antagonist at postsynaptic serotonergic receptors which augment phrenic motoneuronal activity and play a role in the generation of hiccups. Aim: To compare the effectiveness of combination therapy (Olanzapine plus Chlorpromazine) with monotherapy (Chlorpromazine) in Traumatic Brain Injury (TBI) patient admitted to trauma Intensive Care Unit (ICU). Material and Methods: The present study was a control trial which was conducted between November 2020 to October 2021 on patients aged 18-65 years diagnosed with intracranial injury due to trauma. A total of 100 patients (50 in each group) were randomised into Group 1 (patients receiving chlorpromazine 25 mg thrice daily for five days) and Group 2 (patients receiving chlorpromazine 25 mg thrice daily and olanzapine 5 mg once daily for five days). The primary outcome measure was to compare cessation or reduction in the frequency of hiccups. Various laboratory parameters were investigated and compared between both the groups on day zero and day five. The secondary outcome was side-effects of the drugs. Results: In the present study, the distributions of age and gender were similar in both groups with mean age of patients being 39.16±13.88 years and 43.30±12.51 years in group 1 and 2, respectively. Cessation of hiccups were found in 29 (58%) of the patients in group 2 as compared to 27 (54%) patients in group 1, which was not statistically significant. However, improvement in the status of patients was observed in 18 (36%) in group 2, as compared to 10 (20%) in group 1 (p<0.05). No serious adverse events were documented in either groups. Conclusion: A better outcome was observed with combination of chlorpromazine and olanzapine than chlorpromazine alone, in treating hiccups due to TBI. The present trial has established the role of drugs for managing hiccups caused after TBI.

Abstract
Background: Post traumatic seizures (PTS) are very common after traumatic brain injury and occur more common in severe form of injury. Prophylactic treatment with phenytoin has been found to be effective however till now no uniform internationally agreed guideline is available for the duration of anticonvulsant prophylaxis for traumatic brain injury patients. Methods: 100 patients of either sex between age group of 18–65 years who have suffered intracranial injury identified by CT scan, admitted in Trauma ICU were enrolled in this prospective randomized single blinded clinical study. Group 1 (n = 50) received 7 days prophylactic anticonvulsant therapy with phenytoin and Group 2 (n = 50) received for 21 days. The primary end point was the occurrence of seizures, which were classified as early (occurring from time of drug loading to day 7) or late (occurring on day 8 or later after loading of drug). Patients were also assessed for the possible adverse side effects of phenytoin. Result: Out of 100 patients, 90 completed the study successfully as 5 patients from each group expired during the duration of the study. On comparing the frequency of seizure from 1st to 7th day after loading dose of phenytoin between two groups, out of 45 patient, 2 (4.4%) developed seizure in group 1 and 3 (6.7%) developed seizure in group 2 and found to be statistically insignificant (P = 0.645). On comparing the frequency of seizure from 1st to 21st day after loading dose of phenytoin between two groups, out of 45 patient, 4 (8.9%) developed seizure in groups 1 and 3 (11.1%) developed seizure in group 2 and found to be statistically insignificant (P = 0.725). Conclusion: A 21-day prophylactic anticonvulsant therapy with phenytoin was not more effective than a 7-day prophylactic therapy with phenytoin to reduce the frequency of seizure in a TBI patient in trauma ICU and was also associated with more adverse side effects that were insignificant.

Quantitative correlation of colony forming units of Acinetobacter baumannii obtained from endotracheal tube aspirate culture with clinical pulmonary infection score. Indian J Anaesth 2021; 65:S163-S167. [PMID: 34908568 PMCID: PMC8613467 DOI: 10.4103/ija.ija_649_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 10/08/2021] [Accepted: 10/10/2021] [Indexed: 11/13/2022] Open
Abstract
Background and Aims: Ventilator-associated pneumonia (VAP) is the most common healthcare-associated infection in adult critical care units. The reason behind the different levels of severity and the outcome in different individuals is not established yet.Co-morbidities and age may be a valid reason.In an attempt to find out the reason behind the different levels of severity of VAP in different individuals, we conducted a studywith the primary objective being to assess the quantitative correlation between the colony forming units (CFU) of Acinetobacter baumannii in the endotracheal tube aspirate and the Clinical Pulmonary Infection Score (CPIS) in mechanically ventilated patients without co-morbidities. The secondary objective was to see whether the severity of VAP depends on the number of CFU(>105/ml). Methods: This observational study was conducted in a 27-bedded intensive care unit of a tertiary care hospital in northern India. Endotracheal tube aspirate was collected from patients with suspected VAP.A total of 81 patients without any prior co-morbidity and having Acinetobacter baumannii in their endotracheal tube aspirate were included in the study group. Quantification of Acinetobacter baumannii was done by counting CFU.The CPIS was calculated for all Acinetobacter baumannii positive patients. Correlation between CFU of Acinetobacter baumannii and CPIS was assessed using Spearman's Rho correlation coefficient. Results: Among 81 patients having Acinetobacter baumannii infection, only 61.9% had a CPIS >4. There was an insignificant correlation between the quantity of CFUs of Acinetobacter baumannii and CPIS (P value = 0.784). Conclusion: Number of CFU >105/ml in an endotracheal tube aspirate culture bears no relation to the severity of VAP as predicted by the CPIS.

Abstract
Abstract
Introduction
Cardiovascular disease (CVD) is the leading cause of mortality in people with type 2 diabetes (T2D). CAPTURE, a non-interventional, cross-sectional study conducted across 13 countries in 2019, collected demographic and clinical characteristics in almost 10,000 adults with T2D in primary or secondary care. Less than 25% of patients with established CVD treated with a glucose-lowering agent received an agent with demonstrated benefit in cardiovascular (CV) risk reduction, such as a glucagon-like peptide-1 receptor agonist (GLP-1 RA) or a sodium–glucose co-transporter-2 inhibitor (SGLT-2i).1 It is not known whether this is linked to estimated 10-year and lifetime CV risk.
Purpose
To estimate the CV risk distribution in the CAPTURE population using the Diabetes Lifetime-perspective prediction (DIAL) model, and to assess treatment patterns by CV risk.
Methods
The DIAL model is an externally validated competing risk adjusted model for predicting CV risk in patients with T2D, calculating absolute 10-year and lifetime risk of myocardial infarction, stroke or cardiovascular death, and life-expectancy free of a CVD event. Patient-level data from CAPTURE (age, sex, body mass index, smoking status, HbA1c, CVD history, T2D duration, clinical parameters and treatment history) were used in the DIAL model. Missing data were imputed by region using predicted mean matching. High risk was defined as 10-year risk >10%, and lifetime risk >50%.
Results
Data from 9457 patients with T2D aged 30–85 years were included in the analyses. There was a wide distribution of both 10-year and lifetime risk, with higher risk in patients with a history of CVD (n=2914) than in those without (n=6543). Among patients with a history of CVD, 96% had a 10-year risk of CVD >10% and 81% had a lifetime risk of CVD >50% (Figure). In patients with CVD and a high 10-year risk of recurrent CVD, 81% had a lifetime risk of recurrent CVD >50%. In patients without history of CVD, 14% had a 10-year risk >10% and only 1% had a lifetime risk >50% (Figure). Among patients without previous CVD but with a high 10-year risk of CVD, only 4% had a lifetime risk >50%. Of the patients with CVD, 10% received a GLP-1 RA and 18% received an SGLT-2i. Similarly, of patients with CVD and a high 10-year risk of recurrent CVD, 10% received a GLP-1 RA and 17% received an SGLT-2i. Among patients without CVD, 11% received a GLP-1 RA and 16% received an SGLT-2i, and among patients without current CVD but at a high 10-year risk of CVD, 12% received a GLP-1 RA and 16% received an SGLT-2i.
Conclusion
There is a wide distribution of CVD risk in the CAPTURE population, and only a minority of patients at high risk of CVD received a glucose-lowering agent with demonstrated benefit in CV risk reduction. Discussing with patients the 10-year and lifetime risks, and the CV benefit to be gained from interventions, can enhance shared decision making.

Role of early foldscopy (microscopy) of endotracheal tube aspirates in deciding restricted empirical therapy in ventilated patients. Indian J Med Microbiol 2021; 40:96-100. [PMID: 34481691 DOI: 10.1016/j.ijmmb.2021.08.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Revised: 08/07/2021] [Accepted: 08/13/2021] [Indexed: 12/01/2022]
Abstract
PURPOSE Prevention of healthcare-associated infections (HAI) like ventilator associated pneumonia (VAP) is particularly challenging especially in resource limited settings. Complex microbial interactions between patients and health care workers (HCWs) further complicate the situation, requiring a holistic approach for successful management. To bridge the gap between laboratory and intensive care unit (ICU) this study was conducted to find the role of hand-held microscope 'Foldscope' in restricting empirical therapy in intubated patients. METHODS A total of 75 endotracheal aspirates (ETA) were collected from intubated patients in the ICU with (group 1) and without (group 2) VAP. For group 2, those with less than 48 h ventilation and with endotracheal tube (ETT) in situ were considered. Presence of biomass was detected through foldscope and ETA samples were processed for quantitative gram staining (QGS), semi-quantitative and quantitative culture. Phenotypic and genotypic characterization of Acinetobacter baumannii, the commonest isolate, was done and findings were statistically analysed. RESULTS Biomass was present as seen through a foldscope in 45 cases (90%) in group 1 and 17 cases (68%) in group 2. In both the groups, A. baumannii was the most common isolate. Biomass production, significant QGS and culture was significantly more in group 1 (p < 0.05). However, carbapenem resistant A. baumannii (CRAB) was comparably present in both the groups thus showing limited role of empirical carbapenem therapy. CONCLUSIONS Early assessment of biomass in mechanically ventilated patients could provide guidance for empirical antibiotic therapy. Foldscope proved to be an excellent tool for restricting empirical therapy and driving antimicrobial stewardship in low resource settings.

Abstract
In the recent past, wastewater treatment processes performed a pivotal role in accordance with maintaining the sustainable environment and health of mankind at a proper hygiene level. It has been proved indispensable by government regulations throughout the world on account of the importance of preserving freshwater bodies. Human activities, predominantly from industrial sectors, generate an immeasurable amount of industrial wastewater loaded with toxic chemicals, which not only cause dreadful environmental problems, but also leave harmful impacts on public health. Hence, industrial wastewater effluent must be treated before being released into the environment to restrain the problems related to industrial wastewater discharged to the environment. Nowadays, biological wastewater treatment methods have been considered an excellent approach for industrial wastewater treatment process because of their cost-effectiveness in the treatment, high efficiency and their potential to counteract the drawbacks of conventional wastewater treatment methods. Recently, the treatment of industrial effluent through bioreactor has been proved as one of the best methods from the presently available methods. Reactors are the principal part of any biotechnology-based method for microbial or enzymatic biodegradation, biotransformation and bioremediation. This review aims to explore and compile the assessment of the most appropriate reactors such as packed bed reactor, membrane bioreactor, rotating biological contactor, up-flow anaerobic sludge blanket reactor, photobioreactor, biological fluidized bed reactor and continuous stirred tank bioreactor that are extensively used for distinct industrial wastewater treatment.

Abstract
Introduction: Breast cancer is a leading cause of death among women globally. Better outcomes for patients can be ensured by early detection and treatment. Early detection requires a high degree of awareness about the various aspects of cancer including etiology, risk factors, signs and symptoms, and breast self-examination (BSE) practices. The purpose of this study was to assess the knowledge and awareness related to breast cancer along with willingness for treatment, among women in an urban setup in Western India. Materials and Methods: We conducted a cross-sectional study with 500 women belonging to the age group of 18–70 years residing in an urban area of Mumbai. Data were obtained through the use of a structured questionnaire over a period of 6 months (April–September 2016). Results: Over half of the respondents (71.42%) knew the symptoms of breast cancer. Awareness regarding the risk factors was varied. Although most (85.71%) of the respondents knew about BSE, contrastingly very few (38.09%) actually performed it. Awareness regarding diagnostic tests was limited to mammography and biopsy, but 90.47% of the women were willing to undergo these tests. 66.67% of women reported that the best treatment for breast cancer was surgery. Conclusion: Awareness of the different presentations of breast cancers (other than lump) is limited and so is the knowledge pertaining to risk factors. A lower level of education is most likely responsible for the low level of awareness and this is the main obstacle for undergoing regular cancer screening and early detection. There is a need of developing an effective health education programs to educate women about breast cancer, propagate valid information via the media, and promote early detection of breast cancer to ensure better outcomes.

Abstract
Introduction. Carbapenem resistance in Acinetobacter baumannii (A. baumannii) is an emerging global threat.Gap statement. The adaptation strategies of A. baumannii for this emergence as a nosocomial pathogen has been less studied.Aim. This prospective study analysed a sustained outbreak of carbapenem resistant Acinetobacter baumannii (CRAB) in the intensive care unit (ICU) with reference to antimicrobial resistance and virulence in the colonizing and pathogenic isolates under carbapenem stress.Results. The CRAB isolates from initial and sustained outbreak were found harbouring multiple carbapenemase genes. These genes included bla OXA-23 ,bla IMP, bla VIM and bla NDM. From NICU environment three phenotypically carbapenem susceptible isolates were found carrying bla OXA-23, bla IMP, bla VIM genes. Prior imipenem therapy was one of the risk factors (P=0.0016). The outbreak was polyclonal. Under imipenem stress, outbreak isolates showed no loss of carbapenemase genes against stress free conditions (23.7±1.33 days). Biofilm formation increased with imipenem concentration, with outbreak isolates producing highest biomass. While the pathogens showed a slow growth rate on imipenem exposure, the colonisers grew rapidly (P <0.0001).Methods. Sustained outbreak of CRAB was identified in the ICU (July 2015 to December 2017). Risk factors for acquisition of CRAB was studied. A. baumannii isolates were also collected from the environments of ICU and neonatal ICU (NICU) and blood cultures of septic neonates. Isolates were characterized based on antimicrobial susceptibility, genetic profile, integrons carriage and clonality. Biofilm formation and growth kinetics were studied under varying carbapenem stress.Conclusion. Intense carbapenem exposure in the ICU facilitates persistence of CRAB by several adaptations causing sustained outbreaks.

Abstract
Background and Aims: Various biomarkers are used for predicting outcome from sepsis and septic shock but single value doesn't give clear-cut picture. Changing trends of serum lactate and red cell distribution width (RDW) gives more accurate information of patient outcome. So, aim of this prospective observational study was to identify the correlation, for initial and changing trend of blood lactate level and RDW, with 28-day mortality in sepsis and septic shock. Material and Methods: Patient who fulfills the criteria of sepsis and septic shock, according to the consensus conference published in 2016, were included in this study. All patients were resuscitated and managed according to institutional protocol for sepsis and septic shock. Serum lactate and RDW was obtained from arterial blood gas and complete blood count, respectively. Serum lactate and RDW were recorded at 0 h, 6 h, 24 h, day 2, day 3, day 7, week 2, and week 3. Mean between two groups were compared with student t-test. Pearson and Spearman correlation coefficient was used for establishing correlation between two continuous data. P value < 0.05 indicates significant difference between two groups. Results: There is positive correlation between serum lactate and RDW at all-time point in non-survival group while negative correlation was found in survival group except on day1 and 2. Conclusion: Changing trends of serum lactate and RDW can be used as a prognostic marker in patient of sepsis and septic shock.

Abstract
Surgical practice during the coronavirus disease 2019 (COVID-19) pandemic has changed significantly, without supporting data. With increasing experience, a dichotomy of practice is emerging, challenging existing consensus guidelines. One such practice is elective tracheostomy. Here, we share our initial experience of head and neck cancer surgery in a COVID-19 tertiary care centre, emphasizing the evolved protocol of perioperative care when compared to pre-COVID-19 times. This was a prospective study of 21 patients with head and neck cancers undergoing surgery during the COVID-19 pandemic, compared to 193 historical controls. Changes in anaesthesia, surgery, and operating room practices were evaluated. A strict protocol was followed. One patient tested positive for COVID-19 preoperatively. There was a significant increase in pre-induction tracheostomies (28.6% vs 6.7%, P = 0.005), median hospital stay (10 vs 7 days, P = 0.001), and postponements of surgery (57.1% vs 27.5%, P = 0.01), along with a significant decrease in flap reconstructions (33.3% vs 59.6%, P = 0.03). There was no mortality and no difference in postoperative morbidity. No healthcare personnel became symptomatic for COVID-19 during this period. Tracheostomy is safe during the COVID-19 pandemic and rates have increased. Despite increased rescheduling of surgeries and longer hospital stays, definitive cancer care surgery has not been deferred and maximum patient and healthcare worker safety has been ensured.

Abstract
Background: Colistin resistance in Acinetobacter baumannii, the last resort drug for serious infections, is emerging worldwide. There has been paucity of data on this aspect from India, which is one of the largest producers of colistin. We studied colistin resistance in A. baumannii and characterized the isolates with respect to resistance mechanisms and virulence. Methods: A total of 365 A. baumannii isolates were studied. Antimicrobial susceptibility testing was performed as per standards. Colistin resistance mechanisms were studied by mutation detection in pmrA/B and lpxA/C/D genes, phenotypic loss of lipopolysaccharide, presence of mcr1-5 genes, and carbonyl cyanide 3-chlorophenylhydrazone (CCCP) effects. Biofilm formation, desiccation survival, and growth kinetics were studied and statistically analyzed for colistin-resistant and colistin-susceptible isolates. Results: All the colistin-resistant isolates (9, 2.5%) showed multiple mutations at novel sites in pmrA/B and/or lpxA/D genes with reversion of resistance with CCCP. Majority of these isolates (6, 66.6%) were from patients without prior colistin therapy. All received prior carbapenems. The resistant isolates demonstrated no significant difference in biofilm formation and desiccation survival but were slow growers. Conclusion: Mutations in pmrA/B and/or lpxA/D genes were the main resistance mechanism in these colistin-resistant isolates that showed no reduction in fitness.

Abstract
Background and Objectives In this case series, we propose a novel approach to combined vaginal and laparoscopic surgery in which a posterior colpotomy and 2 5-mm abdominal incisions are used to perform benign gynecological procedures. We seek to assess the safety and feasibility of this technique in difficult surgical candidates such as those with obesity or prior laparotomies, as well as to detail intra- and postoperative complications associated with the procedure. Methods We collected demographic, clinical, intra-operative, and postoperative data on 45 women who underwent a combined vaginal and laparoscopic gynecological surgery for benign indications by a single surgeon between February 2013 and August 2017. Results From February 2013 through August 2017, 45 women underwent a combined vaginal and laparoscopic surgery at 2 institutions. Procedures included adnexal surgery (n = 32, 71%), and total hysterectomy (n = 13, 29%). Of patients who underwent adnexal surgery, two had minor postoperative complications. No patients had major complications. In addition, no patients had postoperative vaginal infections or pelvic abscesses, and there were no readmissions within 30 days after the procedures. Conclusion Our proposed combined vaginal and laparoscopic approach to benign gynecological surgery can be utilized in difficult surgical candidates including those with obesity, nulliparous patients, and those with prior abdominal surgery. Our data has shown that this approach is safe and effective.

Abstract
We evaluated the efficacy of topical Myolaxin (capsaican ointment, Geno, Mumbai) ointment over EMLA (eutectic mixture of lignocaine, prilocaine; Neon, Goa) cream for attenuating venous cannulation pain in this prospective, randomised, double blind study. Sixty adult patients undergoing elective laparoscopic cholecystectomy were randomly assigned into two equal groups. Group I (EMLA) received EMLA cream, whereas Group II (Myolaxin) received Myolaxin ointment. For both groups the cream was applied at the venous cannulation site (dorsum of the non-dominant hand) one hour prior to venous cannulation and was covered with an occlusive dressing. Following venous cannulation patients were asked if they felt pain during venous cannulation. If the answer was yes, they were asked to rate the severity of venous cannulation pain using a Visual Analogue Scale (VAS) of O-10. The incidence of venous cannulation pain was similar between groups: in the EMLA group 65% (18/28) compared to 67% (20/30) in the Myolaxin group (P=0.19). The severity of pain (median VAS with inter quartile range) was also similar between the groups: in the EMLA group 1.5 (3) compared to 1.5 (2) in the Myolaxin group (P=0.46). As the topical application of Myolaxin ointment is cheaper than EMLA and has similar efficacy, it may be a suitable alternative for reducing the incidence and severity of venous cannulation pain.

Abstract
OBJECTIVE Aberrant expression of HER2/neu and PIK3CA gene products secondary to amplification/mutations are common in high-grade-serous-endometrial (USC) and ovarian-cancers (HGSOC). Because scant information is currently available in the literature on the potential negative effect of PIK3CA mutations on the activity of afatinib, in this study we evaluate for the first time the role of oncogenic PIK3CA mutations as a potential mechanism of resistance to afatinib in HGSOC and USC overexpressing HER2/neu. METHODS We used six whole-exome-sequenced primary HGSOC/USC cell-lines and three xenografts overexpressing HER2/neu and harboring mutated or wild-type PIK3CA/PIK3R1 genes to evaluate the role of PI3K-mutations as potential mechanism of resistance to afatinib, an FDA-approved pan-c-erb-inhibitor in clinical trials in USC. Primary-USC harboring wild-type-PIK3CA gene was transfected with plasmids encoding oncogenic PIK3CA-mutations (H1047R/E545K). The effect of afatinib on HER2/PI3K/AKT/mTOR pathway was evaluated by immunoblotting. RESULTS We found PI3K wild-type cell-lines to be significantly more sensitive (lower IC50) than PI3K-mutated cell-lines p = 0.004). In vivo, xenografts of primary cell-line USC-ARK2, transfected with the PIK3CA-H1047R or E545K hotspot-mutations, exhibited significantly more rapid tumor growth when treated with afatinib, compared to mice harboring ARK2-tumors transfected with wild-type-PIK3CA (p = 0.041 and 0.001, respectively). By western-blot, afatinib effectively reduced total and phospho-HER2 proteins in all cell-lines. However, H1047R/E545K-PIK3CA-transfected-ARK2-cells demonstrated a greater compensatory increase in phosphorylated-AKT proteins after afatinib exposure when compared to controls ARK2. CONCLUSIONS Oncogenic PI3K mutations may represent a major mechanism of resistance to afatinib. Combinations of c-erb with PIK3CA, AKT or mTOR inhibitors may be necessary to more efficiently block the PIK3CA/AKT/mTOR pathway.

Inhibition of BET Bromodomain Proteins with GS-5829 and GS-626510 in Uterine Serous Carcinoma, a Biologically Aggressive Variant of Endometrial Cancer. Clin Cancer Res 2018; 24:4845-4853. [PMID: 29941483 DOI: 10.1158/1078-0432.ccr-18-0864] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2018] [Revised: 05/18/2018] [Accepted: 06/19/2018] [Indexed: 11/16/2022]
Abstract
Purpose: Uterine serous carcinoma (USC) is a rare and aggressive variant of endometrial cancer. Whole-exome sequencing (WES) studies have recently reported c-Myc gene amplification in a large number of USCs, suggesting c-Myc as a potential therapeutic target. We investigated the activity of novel BET bromodomain inhibitors (GS-5829 and GS-626510, Gilead Sciences Inc.) and JQ1 against primary USC cultures and USC xenografts.Experimental Design: We evaluated c-Myc expression by qRT-PCR in a total of 45 USCs including fresh-frozen tumor tissues and primary USC cell lines. We also performed IHC and Western blot experiments in 8 USC tumors. USC cultures were evaluated for sensitivity to GS-5829, GS-626510, and JQ1 in vitro using proliferation, viability, and apoptosis assays. Finally, the in vivo activity of GS-5829, GS-626510, and JQ1 was studied in USC-ARK1 and USC-ARK2 mouse xenografts.Results: Fresh-frozen USC and primary USC cell lines overexpressed c-Myc when compared with normal tissues (P = 0.0009 and 0.0083, respectively). High c-Myc expression was found in 7 of 8 of primary USC cell lines tested by qRT-PCR and 5 of 8 tested by IHC. In vitro experiments demonstrated high sensitivity of USC cell lines to the exposure to GS-5829, GS-626510, and JQ1 with BET inhibitors causing a dose-dependent decrease in the phosphorylated levels of c-Myc and a dose-dependent increase in caspase activation (apoptosis). In comparative in vivo experiments, GS-5829 and/or GS-626510 were found more effective than JQ1 at the concentrations/doses used in decreasing tumor growth in both USC-ARK1 and USC-ARK2 mouse xenograft models.Conclusions: GS-5829 and GS-626510 may represent novel, highly effective therapeutics agents against recurrent/chemotherapy-resistant USC-overexpressing c-Myc. Clinical studies with GS-5829 in patients with USC harboring chemotherapy-resistant disease are warranted. Clin Cancer Res; 24(19); 4845-53. ©2018 AACR.

A novel multiple biomarker panel for the early detection of high-grade serous ovarian carcinoma. Gynecol Oncol 2018; 149:585-591. [PMID: 29572027 DOI: 10.1016/j.ygyno.2018.03.050] [Citation(s) in RCA: 44] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2018] [Revised: 03/13/2018] [Accepted: 03/15/2018] [Indexed: 12/18/2022]
Abstract
INTRODUCTION Since the majority of patients are diagnosed at an advanced stage, ovarian cancer remains the most lethal gynecologic malignancy. There is no single biomarker with the sensitivity and specificity required for effective cancer screening; therefore, we investigated a panel of novel biomarkers for the early detection of high-grade serous ovarian carcinoma. METHODS Twelve serum biomarkers with high differential gene expression and validated antibodies were selected: IL-1Ra, IL-6, Dkk-1, uPA, E-CAD, ErbB2, SLPI, HE4, CA125, LCN2, MSLN, and OPN. They were tested using Simple Plex™, a multi-analyte immunoassay platform, in samples collected from 172 patients who were either healthy, had benign gynecologic pathologies, or had high-grade serous ovarian adenocarcinomas. The receiver operating characteristic (ROC) curve, ROC area under the curve (AUC), and standard error (SE) of the AUC were obtained. Univariate ROC analyses and multivariate ROC analyses with the combination of multiple biomarkers were performed. RESULTS The 4-marker panel consisting of CA125, HE4, E-CAD, and IL-6 had the highest ROC AUC. When evaluated for the ability to distinguish early stage ovarian cancer from a non-cancer control, not only did this 4-marker panel (AUC=0.961) performed better than CA 125 alone (AUC=0.851; P=0.0150) and HE4 alone (AUC=0.870; P=0.0220), but also performed significantly better than the 2- marker combination of CA125+HE4 (AUC=0.922; P=0.0278). The 4-marker panel had the highest average sensitivity under the region of its ROC curve corresponding to specificity ranging from 100% down to ~95%. CONCLUSION The four-marker panel, CA125, HE4, E-CAD, and IL-6, shows potential in detecting serous ovarian cancer at earlier stages. Additional validation studies using the biomarker combination in ovarian cancer patients are warranted.

Abstract
Grade 3 endometrioid and uterine serous carcinomas (USC) account for the vast majority of endometrial cancer deaths. The purpose of this study was to determine folic acid receptor alpha (FRα) expression in these biologically aggressive (type II) endometrial cancers and evaluate FRα as a targetable receptor for IMGN853 (mirvetuximab soravtansine). The expression of FRα was evaluated by immunohistochemistry (IHC) and flow cytometry in 90 endometrioid and USC samples. The in vitro cytotoxic activity and bystander effect were studied in primary uterine cancer cell lines expressing differential levels of FRα. In vivo antitumor efficacy of IMGN853 was evaluated in xenograft/patient-derived xenograft (PDX) models. Semiquantitative IHC analysis indicated that 41% of the USC patients overexpress FRα. Further, overexpression of FRα (i.e., 2+) was detected via flow cytometry in 22% (2/9) of primary endometrioid and in 27% (3/11) of primary USC cell lines. Increased cytotoxicity was seen with IMGN853 treatment compared with control in 2+ expressing uterine tumor cell lines. In contrast, tumor cell lines with low FRα showed no difference when exposed to IMGN853 versus control. IMGN853 induced bystander killing of FRα = 0 tumor cells. In an endometrioid xenograft model (END(K)265), harboring 2+ FRα, IMGN853 treatment showed complete resolution of tumors (P < 0.001). Treatment with IMGN853 in the USC PDX model (BIO(K)1), expressing 2+ FRα, induced twofold increase in median survival (P < 0.001). IMGN853 shows impressive antitumor activity in biologically aggressive FRα 2+ uterine cancers. These preclinical data suggest that patients with chemotherapy resistant/recurrent endometrial cancer overexpressing FRα may benefit from this treatment. Mol Cancer Ther; 17(5); 1003-11. ©2018 AACR.

Abstract
Background: Diagnosis of myelodysplastic syndromes (MDS) is challenging in the presence of morphological mimickers. Flow cytometric immunophenotyping (FCI) has been added to the diagnostic armamentarium, but its use in clinical practice is variable. Materials and Methods: Bone marrow aspirate samples from 54 patients with a clinical and/or morphological suspicion of MDS were subjected to FCI using a single-tube, 6-colour panel comprising of monoclonal antibodies against CD13, CD11b, CD16, CD34, CD45 and CD56. Analysis was centered on the abnormal maturation pattern of granulocytes, blast percentage (≥3%) and ratio of side scatter peak channel value (SSC-PCV) of granulocytes and lymphocytes. Each of these parameters was assigned a score of 1. Overall sensitivity and specificity of this panel was ascertained to differentiate cytopenia/s of MDS from non-MDS cases. Results: Forty MDS and 14 non-MDS cases were diagnosed based on morphology and cytogenetic results. Twenty control samples were also processed simultaneously for FCI to assign the cutoff for various flow cytometric parameters. A score ≥2 was defined as positive for MDS. Hypogranularity was present in 62.5% cases of MDS. The median SSC-PCV of granulocytes and lymphocytes was 6.16 in the MDS group, 7.9 in the non-MDS group and 8.90 in the control group (p <0.05). This cut-off value of 6.16 had a specificity of 92.5% based on the ROC curve analysis. Abnormal granulocyte maturation patterns for CD13/16, CD13/11b and CD11b/16 dot plots were observed in 95.3, 69.8 and 74.4% cases, respectively. The overall sensitivity and specificity of the panel was found to be 87.5% and 64.2%, respectively. Conclusion: FCI is now an important tool for diagnostic workup in patients presenting with persistent cytopenia with or without morphological evidence of dyspoiesis. Inclusion of objective parameters like SSC-PCV would also reduce inter-lab variability in MDS diagnosis.

Abstract
BACKGROUND Catheter - associated urinary tract infection (CAUTI) remains a critical threat for patients in intensive care unit especially in traumatic brain injury patients with low Glasgow coma score (GCS). Almost all patients in ICU receive antibiotic either prophylactic or therapeutic based on local antibiogram of particular ICU or hospital. For prophylaxis, systemic antibiotics are used. It will be helpful to avoid systemic side effects by introducing antibiotics locally through bladder irrigation. The indwelling urinary catheter is an essential part of modern medical care. AIMS AND OBJECTIVES The primary objective was to study the effect of Neomycin and Polymyxin sulphate solution for bladder wash on CAUTI in traumatic brain injury patients. The secondary objectives was to study the various organisms causing CAUTI and their antibiotic sensitivity and resistance pattern. MATERIALS AND METHODS This was a prospective randomized controlled study performed on 100 patients who met the inclusion criteria at the trauma intensive care unit of Banaras Hindu University between September and February 2016. The patients were randomized into two groups - one was the study group which received Neomycin and Polymyxin Sulphate solution bladder wash, while the other was the control group that received Normal saline bladder wash. Urine samples were collected at certain days and sent for culture and sensitivity. RESULTS There was significant reduction in the incidence of CAUTI in neomycin/polymyxin test group in comparison to normal saline irrigated control group. Out of 50 patients in test group 8 patients and in control group 26 patients was identified as CAUTI positive and they were statistically significant. In our study pseudomonas aeruginosa (51%) was the commonest isolated pathogen. CONCLUSIONS Neomycin and Polymyxin Sulphate bladder wash was effective in preventing CAUTI. It can thus decrease the antibiotic usage thereby preventing the emergence of antibiotic resistance.

Abstract
We present a case of a 42-year-old woman with a pregnancy resulting from in vitro fertilisation and a medical history including two spontaneous abortions, hypercoagulable state and other comorbidities. At 13 4/7 weeks' gestation, during research ultrasonography, the patient was noted to have an anterior succenturiate placental lobe. Following an episode of vaginal bleeding at 21 6/7 weeks, she was diagnosed with a low-lying posterior placental lobe. Velamentous cord insertion, placenta previa and vasa previa were excluded at that time. After elective induction for advanced maternal age at 39 0/7 weeks, arrest of labour and chorioamnionitis resulted in a primary low transverse caesarean section and delivery of a healthy girl at 39 3/7 weeks. Gross examination of the placenta showed an irregular, singleton placenta with an attached succenturiate lobe and a marginally inserting umbilical cord. Both lobes were connected by two vessels.

Abstract
Background: Kv7 neuronal channels are recognized as a potential drug target for anxiolytic effects. We hypothesize that flupirtine as a potassium channel opener would effectively reduce the preoperative anxiety of patients undergoing craniotomy procedure. Methods: In prospective-double-blinded fashion, 124 counseled patients were randomized to receive 5 sequential doses of capsule flupirtine 100 mg (F Group) or physically similar starch capsules (C Group), at 12 h intervals during preoperative hospitalization. Primary outcome included various aspects of patient anxiety measured by visual analog scale (VAS) just before preoperative counseling and 2 h after the completion of drug regimen under trial. Statistical tool included Mann–Whitney U-test and Wilcoxon signed rank test. Results: Baseline VAS scores were higher for fear of surgical harm, being at the mercy of medical staff, and not awakening after surgery. A significant decline in VAS scores was observed after the completion of drug regime, but to a higher extent in flupirtine-treated patients; it achieved statistical significance in comparison to Group C. No side effects were observed in any patient. Conclusion: Flupirtine is a useful premedication in conjunction with behavioral therapy to alleviate patient anxiety during the preoperative period.

Abstract
Background: Mandibular nerve block reverses the trismus caused by pain and muscle spasm, thereby allowing for selection of a safer intubation technique. Aims: As ultrasonographic imaging has added newer dimensions to clinical anesthesia practice, we utilized this tool in performing mandibular nerve block and evaluated its efficacy in segregating trismus patients on etiological basis, to predict safer anesthetic induction. Settings and Design: Prospective, randomized controlled, outcome assessor blinded trial. Materials and Methods: Sixty-eight patients with unilateral mandibular fracture, acute pain, and trismus were randomized to receive mandibular nerve block by Vazirani-Akinosi approach (Group V) or the ultrasound-guided (USG) technique (Group U) before the general anesthetic induction for corrective surgery. Visual Analog Scale (VAS) score and inter-incisor distance was measured at intervals. Primary outcome measure was blocked failure (continued pain [VAS > 30] after the block procedure). Statistical Analysis Used: Mann–Whitney U-test and Wilcoxon signed rank test. Results: There was a significant decrease in pain score following the block procedure, except for six patients (block failure) in Group V. Inter-incisor distance increased to near-maximal levels after the nerve blockade, except for nine patients in Group V (including all block failures) and four in Group U having continued limited mouth opening. General anesthetic induction increased the inter-incisor gap in block failures (Group V) only. Conclusion: USG mandibular block appears to relieve reversible trismus more reliably, thereby allowing for a precise decision on a safer intubation technique.

Abstract
BACKGROUND AND AIMS Poorly managed acute postoperative pain may result in prolonged morbidity. Various pharmacotherapies have targeted this, but research on an ideal preemptive analgesic continues, taking into account drug-related side effects. Considering the better tolerability profile of tapentadol, we assessed its role as a preemptive analgesic in the reduction of postoperative analgesic requirements, after laparoscopic cholecystectomy. MATERIAL AND METHODS In a prospective-double-blinded fashion, sixty patients posted for above surgery, were randomized to receive tablet tapentadol 75 mg (Group A) or starch tablets (Group B) orally, an hour before induction of general anesthesia. Perioperative analgesic requirement, time to first analgesia, pain, and sedation score were compared for first 24 h during the postoperative period and analyzed by one-way analysis of variance test. A P < 0.05 was considered significant. RESULTS Sixty patients were analyzed. The perioperative analgesic requirement was significantly lower in Group A. Verbal numerical score was significantly lower in Group A at the time point, immediately after shifting the patient to the postanesthesia care unit. Ramsay sedation scores were similar between the groups. No major side effects were observed except for nausea and vomiting in 26 cases (10 in Group A, 16 in Group B). CONCLUSION Single preemptive oral dose of tapentadol (75 mg) is effective in reducing perioperative analgesic requirements and acute postoperative pain, without added side effects. It could be an appropriate preemptive analgesic, subjected to future trials concentrating upon its dose-response effects.

Abstract
Interscalene block is a commonly done regional anesthesiatechnique for shoulder and upper arm surgery. It has been used regularly as it is simple and achieves good and satisfactory block, but still it is not completely devoid of complications. In our case we have given interscalene block to a 45 year old male patient of ASA grade-I. Immediately after injecting the local anesthetic drug the patient became unconscious and unresponsive due to total spinal blockade. The patient was resuscitated and shifted to ICU where the he regained his consciousness after few hours and shifted to the ward without any neurological deficit.
