Abstract Brain tumor glioblastoma is a disease that is caused for a child who has abnormal cells in the brain, which is found using MRI “Magnetic Resonance Imaging” brain image using a powerful magnetic field, radio waves, and a computer to produce detailed images of the body's internal structures it is a standard diagnostic tool for a wide range of medical conditions, from detecting brain and spinal cord injuries to identifying tumors and also in evaluating joint problems. This is treatable, and by enabling the factor for happening, the factor for dissolving the dead tissues. If the brain tumor glioblastoma is untreated, the child will go to death; to avoid this, the child has to treat the brain problem using the scan of MRI images. Using the neural network, brain-related difficulties have to be resolved. It is identified to make the diagnosis of glioblastoma. This research deals with the techniques of max rationalizing and min rationalizing images, and the method of boosted division time attribute extraction has been involved in diagnosing glioblastoma. The process of maximum and min rationalization is used to recognize the Brain tumor glioblastoma in the brain images for treatment efficiency. The image segment is created for image recognition. The method of boosted division time attribute extraction is used in image recognition with the help of MRI for image extraction. The proposed boosted division time attribute extraction method helps to recognize the fetal images and find Brain tumor glioblastoma with feasible accuracy using image rationalization against the brain tumor glioblastoma diagnosis. In addition, 45% of adults are affected by the tumor, 40% of children and 5% are in death situations. To reduce this ratio, in this study, the Brain tumor glioblastoma is identified and segmented to recognize the fetal images and find the Brain tumor glioblastoma diagnosis. Then the tumor grades were analyzed using the efficient method for the imaging MRI with the diagnosis result of partially high. The accuracy of the proposed TAE-PIS system is 98.12% which is higher when compared to other methods like Genetic algorithm, Convolution neural network, fuzzy-based minimum and maximum neural network and kernel-based support vector machine respectively. Experimental results show that the proposed method archives rate of 98.12% accuracy with low response time and compared with the Genetic algorithm (GA), Convolutional Neural Network (CNN), fuzzy-based minimum and maximum neural network (Fuzzy min–max NN), and kernel-based support vector machine. Specifically, the proposed method achieves a substantial improvement of 80.82%, 82.13%, 85.61%, and 87.03% compared to GA, CNN, Fuzzy min–max NN, and kernel-based support vector machine, respectively.

The organism is found to cause sepsis and is also reported to cause blood stream infections in malignancy. Here, we present a case series of five patients with sepsis in which an unsual violet pigment producing BCC was isolated. Keywords: Violet pigment, Burkholderia, Sepsis, Malignancy

Background: Subsequent to serosurveys 1 and 2 for COVID-19 carried out in three wards of Mumbai in July and August 2020, Municipal Corporation of Greater Mumbai conducted serosurvey 3 in March 2021. This was to identify the extent of exposure by testing specific IgG antibodies against COVID-19. Material and Methods: A cross-sectional study was conducted to find the prevalence of seropositivity in Mumbai, which included 10,197 samples belonging to patients visiting public dispensaries (slum population, 6006) and private (nonslum population, 4191) laboratories of Aapli Chikitsa network for blood investigations for non-COVID illnesses. The ward-wise number of unlinked anonymous samples from 24 wards was predecided by using probability proportionate sampling. The samples were collected using quota sampling technique as per predecided sample for each ward. These samples collected from nonimmunized individuals were tested for IgG antibodies at the Molecular Biology Laboratory of Kasturba Hospital for Infectious Diseases by chemiluminescence assay (CLIA) method. Results: The overall seropositivity was found to be 36.3% (41.6% in slum and 28.59% in nonslum population). It was more in city wards (38.28%) followed by western suburb (36.47%) and then eastern suburb wards (34.86%), matching with the proportion of cases in these wards during the study period. There was no significant difference in seropositivity among males and females and in different age groups. Conclusions: Seropositivity is higher in slum areas than nonslum areas. It has reduced in slum areas and increased in nonslum areas as compared to findings of serosurveys 1 and 2. This explains the detection of a greater number of cases from nonslum areas in the second wave. The average seropositivity of 36.3% justifies the necessity of immunization on a wider scale in the city. Periodic serosurveys are required at fixed intervals to monitor the trend of infection and level of herd immunity.

Basidiobolus ranarum is an uncommon pathogen in ocular infections. It has been previously reported from subcutaneous and gastrointestinal infections. Here, we report a rare case of ocular infection caused by B. ranarum. A 21-year-old male patient presented with visual loss and pain in the right eye due to corneal abscess following an injury while welding. KOH mount performed was indicative of fungal hyphae. Fungal culture revealed growth of B. ranarum. Meanwhile, the patient was treated with antifungal (topical natamycin and oral ketoconazole) along with total corneal transplantation. B. ranarum is a fungus very uncommonly causing ocular pathogenesis. This results in diagnostic confusion leading to poor treatment outcomes. Hence, a mycology laboratory has to be aware about this fungus and need to consider it as a differential diagnosis in patients with infectious corneal abscess.

Chikungunya fever (CHIKF) is an arbovirus disease caused by chikungunya virus (CHIKV), an alphavirus of Togaviridae family. Transmission follows a human-mosquito-human cycle starting with a mosquito bite. Subsequently, symptoms develop after 2–6 days of incubation, including high fever and severe arthralgia. The disease is self-limiting and usually resolve within 2 weeks. However, chronic disease can last up to several years with persistent polyarthralgia. Overlapping symptoms and common vector with dengue and malaria present many challenges for diagnosis and treatment of this disease. CHIKF was reported in India in 1963 for the first time. After a period of quiescence lasting up to 32 years, CHIKV re-emerged in India in 2005. Currently, every part of the country has become endemic for the disease with outbreaks resulting in huge economic and productivity losses. Several mutations have been identified in circulating strains of the virus resulting in better adaptations or increased fitness in the vector(s), effective transmission, and disease severity. CHIKV evolution has been a significant driver of epidemics in India, hence, the need to focus on proper surveillance, and implementation of prevention and control measure in the country. Presently, there are no licensed vaccines or antivirals available; however, India has initiated several efforts in this direction including traditional medicines. In this review, we present the current status of CHIKF in India.

Introduction: Vulvovaginal Candidiasis (VVC) is one of the commonest vaginal infections caused by Candida spp. affecting women of reproductive age group. Though Candida spp. is of endogenous origin several host related and behavioural factors can contribute to the development of infection. Candida albicans is the commonest spp. responsible for infection. However, an increasing emergence of Non-albicans Candida (NAC) has led to the development of recurrent infections, treatment failure and complications. Aim: To characterise Candida spp. isolated from clinically suspected cases of VVC. Materials and Methods: It was an observational prospective study done during the period of May 2017 to Oct 2018. A total of 150 vaginal isolates from samples of vaginal discharge were included in the study. Candida spp identification was done by various methods like gram stain, germ tube test, culture on Sabouraud Dextrose Agar (SDA), Dalmau culture on corn meal agar, colour differentiation on CHROMagar (Chromogenic agar) and sugar assimilation tests. Statistical Package for Social Science (SPSS) was used for statistical analysis. Results: Women of age group 26-35 years were most commonly affected population. Candida albicans (49.3%) and NAC (50.7%) both were present in almost equal number. The commonest isolate found was Candida albicans (49.3%) followed by Candida glabrata (29.3%) and Candida tropicalis (21.4%). Conclusion: Highest infection rate (54%) was seen in the women of age group 26-35 years. Candida albicans being the commonest spp. As NAC are emerging rapidly, speciation will play a vital role in appropriate selection of antifungal agents for the treatment of fungal infections prior to the initiation of therapy.

PARP-7 (TiPARP) is a mono(ADP-ribosyl) transferase whose protein substrates and biological activities are poorly understood. We observed that PARP7 mRNA levels are lower in ovarian cancer patient samples compared to non-cancerous tissue, but PARP-7 protein nonetheless contributes to several cancer-related biological endpoints in ovarian cancer cells (e.g. growth, migration). Global gene expression analyses in ovarian cancer cells subjected to PARP-7 depletion indicate biological roles for PARP-7 in cell-cell adhesion and gene regulation. To identify the MARylated substrates of PARP-7 in ovarian cancer cells, we developed an NAD+ analog-sensitive approach, which we coupled with mass spectrometry to identify the PARP-7 ADP-ribosylated proteome in ovarian cancer cells, including cell-cell adhesion and cytoskeletal proteins. Specifically, we found that PARP-7 MARylates α-tubulin to promote microtubule instability, which may regulate ovarian cancer cell growth and motility. In sum, we identified an extensive PARP-7 ADP-ribosylated proteome with important roles in cancer-related cellular phenotypes.

The use of sentinel lymph node (SLN) mapping over full lymphadenectomy for endometrioid endometrial cancer (EC) has had varying uptake. Adjuvant therapy for advanced stage EC is also a debated topic globally. Two recent randomized controlled trials have attempted to clarify which treatment approach should be recommended. Our aims were to identify common practice patterns in the intraoperative lymph node evaluation as well as the practice patterns in the treatment of advanced stage (stage III-IV) endometrioid EC among gynecologic oncologists.A 16-question survey was distributed via email to all Society of Gynecologic Oncology members. Study data were collected anonymously and managed using REDCap electronic data tools. Respondents were asked questions regarding demographics, assessing nodal status, and choice of adjuvant treatment for each stage. Descriptive statistics, student’s t-tests, and chi-squared analyses were performed.A total of 1531 surveys were distributed and 187 (12%) members responded. The majority (70%) of respondents identified nodal metastases by performing SLN mapping prior to nodal evaluation in grade 1–2 disease, however only half perform SLN mapping in grade 3 EC. Adjuvant chemotherapy was recommended by 90% of practitioners for advanced EC. However, external beam radiation or brachytherapy was combined with chemotherapy in 74% of stage III EC and 35% of stage IV EC.While 90% of practitioners recommend chemotherapy-based adjuvant treatment for women with stage IIIA–IVA endometrioid EC, decreasing local recurrence appears to be a factor in treatment planning as radiation combined with chemotherapy is used in 63% of cases.

Retrospective studies suggest that minimally-invasive surgery may be safe and effective for the treatment of early-stage ovarian cancer as well as interval cytoreduction after neoadjuvant chemotherapy. Adoption rates and attitudes towards its use remain largely unknown. We aimed to determine the current use of minimally-invasive surgery for the treatment of ovarian cancer and identify perceived barriers towards further adoption of this method. Electronic survey was administered to physician members of the Society of Gynecologic Oncology. Chi-square analysis was used to determine if any correlation existed between variables and the current use of minimally invasive surgery in general practice and, specifically, for the treatment of ovarian cancer. There was a survey response rate of 15.1%. Sixty-five percent of respondents practiced in an academic setting, and 32.1% of respondents had completed fellowship training within the past 5 years. Ninety percent of respondents were performing >50% of their current procedures using minimally invasive surgery. Over seventy percent of respondents said that they performed minimally invasive surgery for primary staging and interval cytoreductive surgery for the treatment of ovarian cancer. Concern for residual disease and lack of scientific validation were the most frequently cited barriers to the implementation of minimally invasive surgery for the treatment of ovarian cancer. A majority of respondents have adopted the use of MIS for the management of early stage ovarian cancer. Advances in imaging to detect occult tumor deposits and a randomized trial to study and promote the use of minimally invasive surgery in ovarian cancer is warranted.

INTRODUCTION: Early diagnosis of dengue is important for appropriate clinical management and vector control. Different serological tests based on the principle of immunochromatography and enzyme-linked immunosorbent assay (ELISA) are commonly used for detection of antigen and antibodies of dengue virus. The performance of these tests depends on the sensitivity and specificity. Hence, the study was undertaken to compare nonstructural protein-1 (NS1) antigen detection by rapid and ELISA with real-time polymerase chain reaction (RT-PCR) for diagnosis of dengue. MATERIALS AND METHODS: Prospective laboratory study was carried out on sera samples (n = 200) from clinically suspected cases of dengue. The sera samples were subjected for NS1 antigen detection test by rapid test, NS1 ELISA, and RT-PCR. The results of rapid and ELISA tests were compared with real Time PCR. RESULTS: The sensitivity, specificity, positive, and negative predictive value of rapid dengue NS1 antigen test were 81.5%, 66.7%, 78.2%, and 71.1%, respectively whereas that of NS1 ELISA were 89.9%, 100%, 100%, and 94%, respectively. Concordance of Rapid NS1 and NS1 ELISA with PCR was 75.5% and 94%. DISCUSSION AND CONCLUSION: NS1 antigen ELISA can be implemented in diagnostic laboratories for diagnosis of dengue in the acute phase of illness. The test also has great potential value for use in epidemic situations, as it could facilitate the early screening of patients and limit disease expansion.

Abstract Background Metastasis via pelvic and/or para-aortic lymph nodes is a major risk factor for endometrial cancer. Lymph-node resection ameliorates risk but is associated with significant co-morbidities. Incidence in patients with stage I disease is 4–22% but no mechanism exists to accurately predict it. Therefore, national guidelines for primary staging surgery include pelvic and para-aortic lymph node dissection for all patients whose tumor exceeds 2cm in diameter. We sought to identify a robust molecular signature that can accurately classify risk of lymph node metastasis in endometrial cancer patients. 86 tumors matched for age and race, and evenly distributed between lymph node-positive and lymph node-negative cases, were selected as a training cohort. Genomic micro-RNA expression was profiled for each sample to serve as the predictive feature matrix. An independent set of 28 tumor samples was collected and similarly characterized to serve as a test cohort. Results A feature selection algorithm was designed for applications where the number of samples is far smaller than the number of measured features per sample. A predictive miRNA expression signature was developed using this algorithm, which was then used to predict the metastatic status of the independent test cohort. A weighted classifier, using 18 micro-RNAs, achieved 100% accuracy on the training cohort. When applied to the testing cohort, the classifier correctly predicted 90% of node-positive cases, and 80% of node-negative cases (FDR = 6.25%). Conclusion Results indicate that the evaluation of the quantitative sparse-feature classifier proposed here in clinical trials may lead to significant improvement in the prediction of lymphatic metastases in endometrial cancer patients.

Background: Chikungunya fever (CHIK) is an arboviral disease. Dengue fever (DENG) and CHIK are indistinguishable clinically and need to be differentiated by laboratory investigations. Purpose: This study aimed at estimating the seroprevalence of CHIK mono-infection and CHIK and DENG dual infection in suspected patients. We also analyzed the age, sex distribution, joint involvement, and relation of joint movement restriction with visual analog scale (VAS). Materials and Methods: Two hundred patients clinically suspected with DENG and CHIK were enrolled from a Tertiary Care Hospital in Mumbai from April 2012 to October 2013. The detailed history and examination findings were recorded. Serum samples were subjected to DENG and CHIK immunoglobulin G (IgM) enzyme-linked immunosorbent assay (ELISA). Results: The seroprevalence of CHIK was 12.5%. Mono-infection of CHIK was 3%, and CHIK and DENG dual infection was 9.5%. Most affected age group in CHIK cases was 46–60 years wherein female preponderance was seen. All 6 patients with CHIK mono-infection had fever and joint involvement; knee and elbow were the most commonly affected joints. All CHIK patients had VAS score of 6–10 with restricted joint movement. Of the patients with dual infection, the majorities were from 31 to 45 years with male preponderance; all had fever and joint pain mainly affecting knee and elbow. Of patients who had VAS score 6–10 in patients with dual infection, only 5.26% had restricted joint movement. Conclusion: IgM ELISA for Chikungunya infection should be included in the routine laboratory tests for acute febrile illness.

Background: Human Immunodeficiency Virus (HIV) is the most powerful risk factor for the progression of Mycobacterium tuberculosis infection to Tuberculosis (TB) disease. TB accelerates the progression of HIV infection to AIDS and shortens the survival of such patients. Aim: To determine the seroprevalence of HIV infection among TB confirmed patients in a tertiary care center in Mumbai in view of the significance of HIV in TB. Its association with gender and age was also determined. Materials and Methods: Blood samples were collected by venipuncture from 432 TB patients and their HIV status was determined. HIV antibody detection was carried out as per Strategy III, National AIDS Control Organisation (NACO) guidelines. Statistical analysis was carried out by applying the Chi-square test. Results and Conclusion: Of the 432 patients screened, 9% (39) were HIV positive. The prevalence of co-infection was higher among females (9.4%) than the male (8.7%) patients and highest amongst those aged 21to40 years (13.7%). Co-infection was found to be statistically highly associated with age (p < 0.05). This high prevalence calls for routine screening of TB patients for HIV infection.

Introduction: Pseudomonas aeruginosa is a frequent colonizer of hospitalized patients. They are responsible for serious infections such as meningitis, urological infections, septicemia and pneumonia. Carbapenem resistance of Pseudomonas aeruginosa is currently increasingly reported which is often mediated by production of metallo-β-lactamase (MBL). Multidrug resistant Pseudomonas aeruginosa isolates may involve reduced cell wall permeability, production of chromosomal and plasmid mediated β lactamases, aminoglycosides modifying enzymes and an active multidrug efflux mechanism. Objective: This study is aimed to detect the presence and the nature of plasmids among metallo-β-lactamase producing Pseudomonas aeruginosa isolates. Also to detect the presence of bla VIM gene from these isolates. Materials and Methods: Clinical isolates of Pseudomonas aeruginosa showing the metalo-β-lactamase enzyme (MBL) production were isolated. The MBL production was confirmed by three different methods. From the MBL producing isolates plasmid extraction was done by alkaline lysis method. Plasmid positive isolates were subjected for blaVIM gene detection by PCR method. Results: Two thousand seventy six clinical samples yielded 316 (15.22%) Pseudomonas aeruginosa isolates, out of which 141 (44.62%) were multidrug resistant. Among them 25 (17.73%) were metallo-β-lactamase enzyme producers. Plasmids were extracted from 18 out of 25 isolates tested. Five out of 18 isolates were positive for the blaVIM gene detection by the PCR amplification. Conclusion: The MBL producers were susceptible to polymyxin /colistin with MIC ranging from 0.5 – 2µg/ml. Molecular detection of specific genes bla VIM were positive among the carbapenem resistant isolates.

Linear porokeratosis of Mibelli (LPM), a variant of porokeratosis, usually appears in childhood, but may occur in middle life. Unilateral lesions frequently occur and are often misdiagnosed. We herewith report a case of linear porokeratosis of Mibelli in a 4 year old girl child clinically mistaken as linear verrucous epidermal nevus.

Nonrotation of intestine is a congenital abnormality of the midgut which is due to error in the process of rotation. Errors in the 2nd and 3rd stage of rotation can lead to series of abnormalities in the form of malrotation and reversed rotation. As a consequence, the relative position of other organs likes caecum, intestine, meckel’s diverticulum changes. This can lead to missing diagnosis of common clinical conditions such as appendicitis. The incidence of nonrotation is 1:500. The congenital abnormality appears to be rare as this could be an incidental abnormality. The symptoms of nonrotation of intestine could be biliary vomiting, recurrent abdominal pain. This could be due to midgut volvulus and intestinal obstruction which happens as a consequence of nonrotation of the intestine. The investigations used for detection and confirmation are CT Imaging. Other associations of nonrotation of the intestine are peritoneal bands. Here we report a case of nonrotation of intestines. In the cadaver of age around 70 years, the small intestinal loops was situated in the right side of the abdominal cavity and large intestine looped on the left side of the abdominal cavity. This was also associated with aberrant position of the caecum and appendix. There were associated peritoneal bands extending from the ascending colon to the left side the abdominal wall. The bands had been removed to visualize the large intestinal loops.

Onychomatricoma is a rare tumor of the nail matrix. A 28 year male presented with asymptomatic gradual appearance of yellowish discoloration and thickening of lateral part of nail of the right index finger of 4 years duration. On examination, a yellow longitudinal band of discoloration involving medial one third of the nail was seen over the index finger of the right hand. The affected part of the natil was thickened and showed over curvature and longitudinal riding. Histopathology showed fibroepithelial elements, confirming the diagnosis of onychomatricoma.

Free standing nanocomposite polymer electrolytes (NCPEs) based on the polymer host poly(vinyl) chloride (PVC) were successfully prepared using the solution casting technique. Lithium nitrate (LiNO3) and nano-sized silica (SiO2) (< 100 nm) were employed as the electrolyte and filler, respectively. Impedance studies revealed a maximum ionic conductivity value of 1.226 × 10−4 S/cm at room temperature for the PVC/LiNO3 with 5 wt.% nano-SiO2. X-ray diffraction (XRD) analysis verified the sample's amorphous nature. Dielectric permittivity and relaxation time values were consistent with impedance results. Additionally, parameters such as diffusion coefficient, mobile concentration, and mobility were evaluated for the prepared samples. Differential scanning calorimetry (DSC) studies confirmed a change in glass transition temperature (Tg) of PVC/LiNO3/SiO2 sample. The scanning electron micrograph (SEM) images revealed a honeycomb morphology, indicating ease of Li+ ion transportation. [ABSTRACT FROM AUTHOR]

In lithium–polymer batteries, the electrolyte is an essential component that plays a crucial role in ion transport and has a substantial impact on the battery's overall performance, stability, and efficiency. This article presents a detailed study on developing nanostructured composite polymer electrolytes (NCPEs), prepared using the solvent casting technique. The materials selected for this investigation include poly(vinyl chloride) (PVC) as the host polymer, lithium bromide (LiBr) as the salt, and silica (SiO2) as the nanofiller. The addition of nano-SiO2 dramatically enhanced the ionic conductivity of the electrolytes, with the highest value of 6.2 × 10−5 Scm−1 observed for the sample containing 7.5 wt% nano-SiO2. This improvement is attributed to an increased amorphicity resulting from the interactions between the polymer, salt, and filler components. A structural analysis of the prepared NCPEs using X-ray diffraction revealed the presence of both crystalline and amorphous phases, further validating the enhanced ionic transport. Additionally, the thermal stability of the NCPEs was found to be excellent, withstanding temperatures up to 334 °C, thereby reinforcing their potential application in lithium–polymer batteries. This work explores the electrochemical performance of a fabricated lithium-ion-conducting primary electrochemical cell (Zn + ZnSO4·7H2O|PVC: LiBr: SiO2|PbO2 + V2O5), which demonstrated an open circuit voltage of 2.15 V. The discharge characteristics of the fabricated cell were thoroughly studied, showcasing the promising potential of these NCPEs. With the support of superior morphological and electrical properties, as-prepared electrolytes offer an effective pathway for future advancements in lithium–polymer battery technology, making them a highly viable candidate for enhanced energy storage solutions.

Biopolymer electrolytes based on methyl cellulose (MC) and sodium bromide(NaBr) have been prepared through solvent casting technique. Both the concentrations of MC and NaBr are varied. The prepared biopolymer electrolytes have been subjected to AC impedance and UV-Vis spectroscopic techniques. The ionic conductivity reached a maximum value of 4.84 × 10−8 Scm−1 for 0.8 g of MC and 0.2 g of NaBr. UV studies revealed that low direct and indirect band gaps have been observed for the maximum ionic conducting sample. Other optical parameters, such as refractive index, extinction coefficient, skin depth, and optical conductivity, have been estimated. The single-oscillator energy (Eo) and dispersion energy (Ed) for all the prepared biopolymer electrolyte samples were calculated with the help of Wemple and DiDomenico single oscillator model. The higher-order non-linear susceptibility values were also calculated. Polymer electrolytes are found to be suitable for optical and electronic devices. [ABSTRACT FROM AUTHOR]
