    Background: Pseudomonas aeruginosa is one of the most frequent opportunistic microorganisms causing infections in cancer patients. The aim of the study was to determine the antibiotic susceptibility of Pseudomonas aeruginosa and multidrug-resistant (MDR) isolates in cancer patients. Methods: A retrospective study was conducted from January 2022 to December 2022 at Government Cancer Hospital, Aurangabad. A total of 143 pus samples were collected from both IPD and OPD patients. Pus samples were collected as per standard procedure and were inoculated on blood and MacConkey agar. The isolates were identified by standard protocols using biochemical tests. The antibiotic susceptibility pattern of each isolate was checked as per Clinical and Laboratory Standards Institute (CLSI) guidelines 2022 using Kirby-Bauer's disc diffusion method and VITEK 2 Automation. Data analysis was done by statical method with statistical software SPSS version 22. Results: Out of 143 clinical samples 33 samples (23%) were positive for Pseudomonas aeruginosa growth. mean age of patients was 50 years old out of 33 isolates 12 (36%) isolates were multidrug-resistant, 11 (33%) isolates were extensively drug-resistant and 1 (3%) were pan-drug-resistant. The majority of isolates were responsive to polymyxin B 32 (96%) and colistin 32 (96%); However, the resistance to gentamycin, ceftazidime, and amikacin was higher, at 66%, 60%, and 57%, respectively.   Conclusions: This hospital-based retrospective study will help to implement better infection control strategies and improve the knowledge of antibiotic resistance patterns among clinicians. Thus, there is a need for an antibiotic stewardship program to monitor the resistant pattern in a tertiary care   cancer hospital

    Introduction. The awareness level among diabetic patients varies across patient population based on many factors such as differences in the literacy of the study population, socioeconomic status, availability of diabetes education. Hence, it is important to study the same in our set-up to plan appropriate preven- tive strategies. The present research work attempted to assess the awareness level about diabetes and its complications among diabetic patients attending a tertiary care teaching hospital.  Materials and methods. This is a hospital based, cross- sectional study, done in diabetic patients attending a tertiary care teaching hospital in South India. The awareness level of the patient was assessed using a pretested questionnaire. The questionnaire had 25 questions (knowledge — 18, attitude — 4 and prac- tice — 3) and each correct answer was given a score of ‘one’ and each wrong answer was given a score of ‘zero’. Patients were assessed clinically for the presence of micro and macrovascular complications and basic investigations were carried out. Metabolic control is assessed by HbA1c level.  Results. A total of 150 patients were included in the study. Approx. 52.6% of patients scored between 14 and 18 (sufficient awareness), 6.6% of patients had satisfactory awareness (KAP score 19–20) and 4% of patients had highly satisfactory awareness (KAP score > 20). Only eight patients had a score less than 10 (highly insufficient awareness) and 31.3% had insufficient awareness (KAP score 10–13). A positive correlation between educational qualification and awareness level was observed (r = 0.495, p < 0.001). Mean awareness score of patients who received diabetes education from physician and dietitian was significantly high when compared to other sources of patient education. Mean awareness scores were lower for those with various diabetic complications. There is a statistically signifi- cant negative correlation observed between awareness and HbA1c values (r = 0.527, p < 0.001).  Conclusion. Majority of the patients had sufficient awareness about the disease and about one-third of the patients had insufficient awareness about diabetes. The awareness level of the patients about the disease had a strong influence on the metabolic control, diabetic complications and also correlated with their educational status.

    Abstract: The idea is to develop a table-inbuilt console based interactive system for manual ordering system. This interactive system can be used in coffee shops, clubs, public restaurants or bars. The aim is to provide every table with a touch screen based console that can be used by customers as an interactive interface between the customers as well as restaurant manager or administrator. Our system will allow the user to view menu items and order them accordingly. The consoles shall be centrally connected to a central server where actual centralized order processing of all clients can be done. A single administrator can view / monitor all the orders from this centralized server. The system also saves time for both customers as well as hotel owner for order placement

    Sociobiological Control of Plasmid copy number

    Get PDF
    Background:
All known mechanisms and genes responsible for the regulation of plasmid replication lie with the plasmid rather than the chromosome. It is possible therefore that there can be copy-up mutants. Copy-up mutants will have within host selective advantage. This would eventually result into instability of bacteria-plasmid association. In spite of this possibility low copy number plasmids appear to exist stably in host populations. We examined this paradox using a computer simulation model.

Model:
Our multilevel selection model assumes a wild type with tightly regulated replication to ensure low copy number. A mutant with slightly relaxed replication regulation can act as a “cheater” or “selfish” plasmid and can enjoy a greater within-host-fitness. However the host of a cheater plasmid has to pay a greater cost. As a result, in host level competition, host cell with low copy number plasmid has a greater fitness. Furthermore, another mutant that has lost the genes required for conjugation was introduced in the model. The non-conjugal mutant was assumed to undergo conjugal transfer in the presence of another conjugal plasmid in the host cell.

Results:
The simulatons showed that if the cost of carrying a plasmid was low, the copy-up mutant could drive the wild type to extinction or very low frequencies. Consequently, another mutant with a higher copy number could invade the first invader. This process could result into an increasing copy number. However above a certain copy number within-host selection was overcompensated by host level selection leading to a rock-paper-scissor (RPS) like situation. The RPS situation allowed the coexistence of high and low copy number plasmids. The non-conjugal “hypercheaters” could further arrest the copy numbers to a substantially lower level.

Conclusions:
These sociobiological interactions might explain the stability of copy numbers better than molecular mechanisms of replication regulation alone

    We report graft-versus-host disease (GVHD)-free relapse-free survival (GRFS) (a composite end point of survival without grade III-IV acute GVHD [aGVHD], systemic therapy-requiring chronic GVHD [cGVHD], or relapse) and cGVHD-free relapse-free survival (CRFS) among pediatric patients with acute leukemia (n = 1613) who underwent transplantation with 1 antigen-mismatched (7/8) bone marrow (BM; n = 172) or umbilical cord blood (UCB; n = 1441). Multivariate analysis was performed using Cox proportional hazards models. To account for multiple testing, P \u3c .01 for the donor/graft variable was considered statistically significant. Clinical characteristics were similar between UCB and 7/8 BM recipients, because most had acute lymphoblastic leukemia (62%), 64% received total body irradiation-based conditioning, and 60% received anti-thymocyte globulin or alemtuzumab. Methotrexate-based GVHD prophylaxis was more common with 7/8 BM (79%) than with UCB (15%), in which mycophenolate mofetil was commonly used. The univariate estimates of GRFS and CRFS were 22% (95% confidence interval [CI], 16-29) and 27% (95% CI, 20-34), respectively, with 7/8 BM and 33% (95% CI, 31-36) and 38% (95% CI, 35-40), respectively, with UCB (P \u3c .001). In multivariate analysis, 7/8 BM vs UCB had similar GRFS (hazard ratio [HR], 1.12; 95% CI, 0.87-1.45; P = .39), CRFS (HR, 1.06; 95% CI, 0.82-1.38; P = .66), overall survival (HR, 1.07; 95% CI, 0.80-1.44; P = .66), and relapse (HR, 1.44; 95% CI, 1.03-2.02; P = .03). However, the 7/8 BM group had a significantly higher risk for grade III-IV aGVHD (HR, 1.70; 95% CI, 1.16-2.48; P = .006) compared with the UCB group. UCB and 7/8 BM groups had similar outcomes, as measured by GRFS and CRFS. However, given the higher risk for grade III-IV aGVHD, UCB might be preferred for patients lacking matched donors. © 2019 American Society of Hematology. All rights reserved

    Evaluation of chemiluminescence, toluidine blue and histopathology for detection of high risk oral precancerous lesions: A cross-sectional study

    <p>Abstract</p> <p>Background</p> <p>Early detection holds the key to an effective control of cancers in general and of oral cancers in particular. However, screening procedures for oral cancer are not straightforward due to procedural requirements as well as feasibility issues, especially in resource-limited countries.</p> <p>Methods</p> <p>We conducted a cross-sectional study to compare the performance of chemiluminescence, toluidine blue and histopathology for detection of high-risk precancerous oral lesions. We evaluated 99 lesions from 55 patients who underwent chemiluminescence and toluidine blue tests along with biopsy and histopathological examination. We studied inter-as well as intra-rater agreement in the histopathological evaluation and then using latent class modeling, we estimated the operating characteristics of these tests in the absence of a reference standard test.</p> <p>Results</p> <p>There was a weak inter-rater agreement (kappa < 0.15) as well as a weak intra-rater reproducibility (Pearson's r = 0.28, intra-class correlation rho = 0.03) in the histopathological evaluation of potentially high-risk precancerous lesions. When compared to histopathology, chemiluminescence and toluidine blue retention had a sensitivity of 1.00 and 0.59, respectively and a specificity of 0.01 and 0.79, respectively. However, latent class analysis indicated a low sensitivity (0.37) and high specificity (0.90) of histopathological evaluation. Toluidine blue had a near perfect high sensitivity and specificity for detection of high-risk lesions.</p> <p>Conclusion</p> <p>In our study, there was variability in the histopathological evaluation of oral precancerous lesions. Our results indicate that toluidine blue retention test may be better suited than chemiluminescence to detect high-risk oral precancerous lesions in a high-prevalence and low-resource setting like India.</p

    Comparative analysis of calcineurin-inhibitor-based methotrexate and mycophenolate mofetil-containing regimens for prevention of Graft-versus-Host Disease after reduced intensity conditioning allogeneic transplantation

    The combination of a calcineurin inhibitor (CNI) such as tacrolimus (TAC) or cyclosporine (CYSP) with methotrexate (MTX) or with mycophenolate mofetil (MMF) has been commonly used for graft-versus-host disease (GVHD) prophylaxis after reduced-intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (alloHCT), but there are limited data comparing efficacy of the 2 regimens. We evaluated 1564 adult patients who underwent RIC alloHCT for acute myelogenous leukemia (AML) and acute lymphoblastic leukemia (ALL), chronic myelogenous leukemia (CML), and myelodysplastic syndrome (MDS) from 2000 to 2013 using HLA-identical sibling (matched related donor [MRD]) or unrelated donor (URD) peripheral blood graft and received CYSP or TAC with MTX or MMF for GVHD prophylaxis. Primary outcomes of the study were acute and chronic GVHD and overall survival (OS). The study divided the patient population into 4 cohorts based on regimen: MMF-TAC, MMF-CYSP, MTX-TAC, and MTX-CYSP. In the URD group, MMF-CYSP was associated with increased risk of grade II to IV acute GVHD (relative risk [RR], 1.78; P < .001) and grade III to IV acute GVHD (RR, 1.93; P = .006) compared with MTX-TAC. In the URD group, use of MMF-TAC (versus MTX-TAC) lead to higher nonrelapse mortality. (hazard ratio, 1.48; P = .008). In either group, no there was no difference in chronic GVHD, disease-free survival, and OS among the GVHD prophylaxis regimens. For RIC alloHCT using MRD, there are no differences in outcomes based on GVHD prophylaxis. However, with URD RIC alloHCT, MMF-CYSP was inferior to MTX-based regimens for acute GVHD prevention, but all the regimens were equivalent in terms of chronic GVHD and OS. Prospective studies, targeting URD recipients are needed to confirm these results

    <p>Abstract</p> <p>Background</p> <p>A large proportion of the 2.5 million new adult HIV infections that occurred worldwide in 2007 were in stable couples. Feasible and acceptable strategies to improve HIV prevention in a conjugal context are scarce. In the preparatory phase of the ANRS 12127 Prenahtest multi-site HIV prevention trial, we assessed the acceptability of couple-oriented post-test HIV counseling (COC) and men's involvement within prenatal care services, among pregnant women, male partners and health care workers in Cameroon, Dominican Republic, Georgia and India.</p> <p>Methods</p> <p>Quantitative and qualitative research methods were used: direct observations of health services; in-depth interviews with women, men and health care workers; monitoring of the COC intervention and exit interviews with COC participants.</p> <p>Results</p> <p>In-depth interviews conducted with 92 key informants across the four sites indicated that men rarely participated in antenatal care (ANC) services, mainly because these are traditionally and programmatically a woman's domain. However men's involvement was reported to be acceptable and needed in order to improve ANC and HIV prevention services. COC was considered by the respondents to be a feasible and acceptable strategy to actively encourage men to participate in prenatal HIV counseling and testing and overall in reproductive health services.</p> <p>Conclusions</p> <p>One of the keys to men's involvement within prenatal HIV counseling and testing is the better understanding of couple relationships, attitudes and communication patterns between men and women, in terms of HIV and sexual and reproductive health; this conjugal context should be taken into account in the provision of quality prenatal HIV counseling, which aims at integrated PMTCT and primary prevention of HIV.</p
