Artificial Intelligence-driven Digital Cytology-based Cervical Cancer Screening: Is the Time Ripe to Adopt This Disruptive Technology in Resource-constrained Settings? A Literature Review.

Cervical cancer is still a public health scourge in the developing countries due to the lack of organized screening programs. Though liquid-based cytology methods improved the performance of cervical cytology, the interpretation still suffers from subjectivity. Artificial intelligence (AI) algorithms have offered objectivity leading to better sensitivity and specificity of cervical cancer screening. Whole slide imaging (WSI) that converts a glass slide to a virtual slide provides a new perspective to the application of AI, especially for cervical cytology. In the recent years, there have been a few studies employing various AI algorithms on WSI images of conventional or LBC smears and demonstrating differing sensitivity/specificity or accuracy at detection of abnormalities in cervical smears. Considering the interest in AI-based screening modalities, this well-timed review intends to summarize the progress in this field while highlighting the research gaps and providing future research directions.

Research and academic output evaluation for career initiation or progression: Critical issues for Health Professionals.

In current times, much stress is being laid on the evaluation of research productivity of researchers or faculty in addition to the academic qualifications and experience for the purposes of recruitment, promotion, and research grant funding. Over the years, several quantitative indices have been devised for this purpose. Some of these indices such as h-index, impact factor and e-index are being extensively used by research organizations, universities, accreditation bodies and funding agencies for basic scientists as well as health professionals. In the absence of any formal training, these parameters or their advantages and shortcomings may not be well understood by the health professionals, especially in the early stages of their careers and sometimes, even by the evaluators. A big unanswered question is the validity of the same criteria for health professionals as are applicable for the basic science researchers. Since health professional undertaking research assignments are neither adequately trained in basic research nor can they comprehend these indices well, the same yardstick to evaluate these two widely different groups of researchers often places the health professionals at a disadvantage.This paper aims to highlight certain vital issues related to the application of research productivity indicators for recruitment and career progression of health care professionals.

Knowledge, Practice, and Skills in Cytology-Based Cervical Cancer Screening: Impact Assessment of Training Workshop for the Pathologists.

There is a paucity of trained cytopathologists in low-resource settings for effective cervical cancer screening. There has been no documented report of the impact of a dedicated training program in cervical cytology on pathologists' knowledge and skill in this field. The present study aimed to evaluate the efficacy of the regularly conducted training workshops on the attending pathologists' knowledge, practice, and skills in cervicovaginal smear reporting. Our institute, a premier cancer research institute, has conducted 10 cytology-based cervical cancer screening workshops for pathologists with pre- and post-training evaluation using sets of digital images and a questionnaire (knowledge score). Additionally, feedback on diagnostic skills was taken at a 1-month and 6-month interval post-workshop using a separate set of digital images of cervical lesions. A Google form-based questionnaire was designed to seek the participants' feedback on the perceived improvement in knowledge and skills. All the data thus collected were analyzed to assess the efficacy of these workshops in imparting the desired knowledge and skills. A total of 350 participants were enrolled in these workshops. The average knowledge score improved from 10.56 (± 3.23) in the pre-training questionnaire to 21.17 (± 2.41) in the post-training evaluation, making a 100.5% increase (P < 0.001). Similarly, the diagnostic accuracy on digital images was enhanced from 8.6 (± 2.12) to 19.5 (± 4.28) immediately post-training and was maintained at 17.6 (± 3.87) at 1-month and 16.4 (± 4.26) at a 6-month interval (P < 0.001). The majority of the participants reported fair to a marked improvement in their knowledge, practice, and confidence in reporting cervical cytology in the response to form-based questionnaire. One-fifth of the responders also acknowledged the assistance of the knowledge gained during the workshop in refinement or initiation of cervical cytology at their set-up. Our experience of conducting these regular workshops demonstrates the utility of such training programs in human resource development in the field of cervical cytology for enhancement of cervical cancer screening in resource-constrained settings.

Health data from diaries used in low-income communities, north India.

OBJECTIVE: To determine the acceptability of keeping a self-written health diary among members of low-income communities, with the aim of generating needed health data. METHODS: We identified three different types of impoverished communities (tribal, inner-city slum and rural) in north India, and conducted a baseline survey to establish the sociodemographic properties of the members of 595 (tribal), 446 (slum) and 51 (rural) households. We designed health diaries with a single page to fill in per month, each with a carbon duplicate, and distributed diaries to willing participants. Health volunteers visited households each month to assist with diary completion and to collect duplicate pages for a period of one year. We compared the frequency of illnesses reported in health diaries with baseline survey data. FINDINGS: A total of 4881 diary users (tribal: 2205; slum: 2185; rural: 491) participated in our project. In terms of acceptability, 49.6% (1093/2205), 64.7% (1413/2185) and 79.0% (388/491) at the tribal, slum and rural sites, respectively, expressed satisfaction with the scheme and a willingness to continue. In the tribal and slum areas, we observed increased reporting of illnesses from health diaries when compared with baseline data. We observed that influenza-like illnesses were reported with the highest frequency of 58.9% (2972/5044) at the tribal site. CONCLUSION: We observed high levels of acceptability and participation among the communities. From our initial field studies, we have observed the benefits to both our study participants (timely preventive education and referrals) and to service providers (obtaining health data to allow improved planning).

Development and testing of implanted carbon electrodes for electromagnetic field mapping during neuromodulation.

PURPOSE: Deep brain stimulation electrodes composed of carbon fibers were tested as a means of administering and imaging magnetic resonance electrical impedance tomography (MREIT) currents. Artifacts and heating properties of custom carbon-fiber deep brain stimulation (DBS) electrodes were compared with those produced with standard DBS electrodes. METHODS: Electrodes were constructed from multiple strands of 7-µm carbon-fiber stock. The insulated carbon electrodes were matched to DBS electrode diameter and contact areas. Images of DBS and carbon electrodes were collected with and without current flow and were compared in terms of artifact and thermal effects in phantoms or tissue samples in 7T imaging conditions. Effects on magnetic flux density and current density distributions were also assessed. RESULTS: Carbon electrodes produced magnitude artifacts with smaller FWHM values compared to the magnitude artifacts around DBS electrodes in spin echo and gradient echo imaging protocols. DBS electrodes appeared 269% larger than actual size in gradient echo images, in sharp contrast to the negligible artifact observed in diameter-matched carbon electrodes. As expected, larger temperature changes were observed near DBS electrodes during extended RF excitations compared with carbon electrodes in the same phantom. Magnitudes and distribution of magnetic flux density and current density reconstructions were comparable for carbon and DBS electrodes. CONCLUSION: Carbon electrodes may offer a safer, MR-compatible method for administering neuromodulation currents. Use of carbon-fiber electrodes should allow imaging of structures close to electrodes, potentially allowing better targeting, electrode position revision, and the facilitation of functional imaging near electrodes during neuromodulation.

Reappraisal of cytology-histology correlation in cervical cytology based on the recent American Society of Cytopathology guidelines (2017) at a cancer research centre.

OBJECTIVE: To assess the impact of recently published American Society of Cytopathology (ASC) guidelines (2017) on the conduct of cervical cytology-histology correlation (CHC). METHODS: A retrospective review was conducted for cervical biopsies with their corresponding conventional cervical smears over a 7.5-year period (January 2011-June 2018). As per the ASC guidelines, a discrepancy assessment grid was prepared. Major cytology-histology discordance was defined as a diagnosis of high-grade squamous intraepithelial lesion (HSIL) or CIN2+ in one of the tests with negative result in the other. Smears and biopsies of all discordant cases were reviewed for reasons of overcall and undercall. RESULTS: Of the 341 cervical biopsies with corresponding Papanicolaou smear, cytology-histology agreement was noted in 249 (73%) cases. Major discordance was observed in 22 cases (6.4%)-16 undercalls and six overcalls on cytology-while minor discrepancies were noted in 70 cases. Atypical metaplasia and repair changes were the main reasons for overcall while small HSIL cells in atrophic smear and scant HSIL cells were important causes of undercall on cytology review. Using the ASC guidelines, we could improvise upon the existing CHC methodology for categorisation of cyto-histological pairs of cases with a cytological diagnosis of atypical glandular cells. CONCLUSION: The present study demonstrates, for the first time, that the recent ASC guidelines facilitate cervical CHC, especially for categorisation of cases with atypical glandular cells on cytology. Uniform application of these guidelines would standardise the conduct of cervical CHC internationally and provide scope for inter-laboratory comparison of data as well as enhance self-learning and peer learning.

Whole Slide Imaging (WSI) in Pathology: Current Perspectives and Future Directions.

Whole slide imaging (WSI), ever since its first introduction about two decades ago, has been validated for a number of applications in the field of pathology. The recent approval of US FDA to a WSI system for use in primary surgical pathology diagnosis has opened avenues for wider acceptance and application of this technology in routine practice. The ongoing technological advances in digital scanners, image visualization methods, and the integration of artificial intelligence-derived algorithms with these systems provide opportunities of its newer applications. Its benefits are innumerable such as ease of access through internet, avoidance of physical storage space, and no risk of deterioration of staining quality or breakage of slides to name a few. Various barriers such as the high cost, technical glitches, and professional hesitation to adopt a new technology have hindered its use in pathology. This review article summarizes the technical aspects of WSI, its applications in diagnostic pathology, training, and research along with future perspectives. It highlights the benefits, limitations, and challenges delaying the use of this technology in routine practice. The review is targeted at students, residents, and budding pathologists to better acquaint them with the key aspects of state-of-the-art technology and enable them to implement WSI judiciously.

Differential Iron Status and Trafficking in Blood and Placenta of Anemic and Non-anemic Primigravida Supplemented with Daily and Weekly Iron Folic Acid Tablets.

ABSTRACT: The molecular mechanism of iron transfer across placenta in response to maternal anemic status/ iron supplementation is not clear. We hypothesized that maternal iron/ anemia status during early trimesters can be utilized as a biomarker tool to get estimates of placental iron status. Early interventions can be envisaged to maintain optimum placental/ foetal iron levels for healthy pregnancy outcomes. One hundred twenty primigravida were recruited and divided into non-anemic and anemic group on the basis of hemoglobin levels. The groups were randomly allocated to receive daily and weekly iron folic acid (IFA) tablets till six weeks postpartum. Hematological and iron status markers in blood and placenta were studied along with the delivery notes. Weekly IFA supplementation in anemic primigravidas resulted in significantly reduced levels of hematological markers (p < 0.01); whereas non-anemic primigravidas showed lower ferritin and iron levels, and higher soluble transferrin receptor levels (p < 0.05). At baseline, C-reactive protein and cortisol hormone levels were also significantly lower in non-anemic primigravidas (p < 0.05). A significantly decreased placental ferritin expression (p < 0.05); and an increased placental transferrin expression was seen in anemic primigravidas supplemented with weekly IFA tablets. A significant positive correlation was observed between serum and placental ferritin expression in anemic pregnant women (r = 0.80; p < 0.007). Infant weight, gestational length and placental weight were comparable in both the supplementation groups. To conclude, mother's serum iron / anemia status switches the modulation in placental iron transporter expression for delivering the optimum iron to the foetus for healthy pregnancy outcomes.

Association of dietary intake below recommendations and micronutrient deficiencies during pregnancy and low birthweight.

Background Pregnancy is associated with biochemical changes leading to increased nutritional demands for the developing fetus that result in altered micronutrient status. The Indian dietary pattern is highly diversified and the data about dietary intake patterns, blood micronutrient profiles and their relation to low birthweight (LBW) is scarce. Methods Healthy pregnant women (HPW) were enrolled and followed-up to their assess dietary intake of nutrients, micronutrient profiles and birthweight using a dietary recall method, serum analysis and infant weight measurements, respectively. Results At enrolment, more than 90% of HPW had a dietary intake below the recommended dietary allowance (RDA). A significant change in the dietary intake pattern of energy, protein, fat, vitamin A and vitamin C (P < 0.001) was seen except for iron (Fe) [chi-squared (χ2) = 3.16, P = 0.177]. Zinc (Zn) deficiency, magnesium deficiency (MgDef) and anemia ranged between 54-67%, 18-43% and 33-93% which was aggravated at each follow-up visit (P ≤ 0.05). MgDef was significantly associated with LBW [odds ratio (OR): 4.21; P = 0.01] and the risk exacerbate with the persistence of deficiency along with gestation (OR: 7.34; P = 0.04). Pre-delivery (OR: 0.57; P = 0.04) and postpartum (OR: 0.37; P = 0.05) anemia, and a vitamin A-deficient diet (OR: 3.78; P = 0.04) were significantly associated with LBW. LBW risk was much higher in women consuming a vitamin A-deficient diet throughout gestation compared to vitamin A-sufficient dietary intake (OR: 10.00; P = 0.05). Conclusion The studied population had a dietary intake well below the RDA. MgDef, anemia and a vitamin A-deficient diet were found to be associated with an increased likelihood of LBW. Nutrient enrichment strategies should be used to combat prevalent micronutrient deficiencies and LBW.

Multishot echo-planar MREIT for fast imaging of conductivity, current density, and electric field distributions.

PURPOSE: Magnetic resonance electrical impedance tomography (MREIT) sequences typically use conventional spin or gradient echo-based acquisition methods for reconstruction of conductivity and current density maps. Use of MREIT in functional and electroporation studies requires higher temporal resolution and faster sequences. Here, single and multishot echo planar imaging (EPI) based MREIT sequences were evaluated to see whether high-quality MREIT phase data could be obtained for rapid reconstruction of current density, conductivity, and electric fields. METHODS: A gel phantom with an insulating inclusion was used as a test object. Ghost artifact, geometric distortion, and MREIT correction algorithms were applied to the data. The EPI-MREIT-derived phase-projected current density and conductivity images were compared with simulations and spin-echo images as a function of EPI shot number. RESULTS: Good agreement among measures in simulated, spin echo, and EPI data was achieved. Current density errors were stable and below 9% as the shot number decreased from 64 to 2, but increased for single-shot images. Conductivity reconstruction relative contrast ratios were stable as the shot number decreased. The derived electric fields also agreed with the simulated data. CONCLUSIONS: The EPI methods can be combined successfully with MREIT reconstruction algorithms to achieve fast imaging of current density, conductivity, and electric field.

Micronutrients Drift During Daily and Weekly Iron Supplementation in Non-anaemic and Anaemic Pregnancy.

AIMS: Pregnancy is a phenomenon associated with dynamic changes in physical, mental and biochemical status of body and demands increased nutritional intake for developing foetus. The level of various micronutrients which act as co-factors for antioxidant enzymes or it-self as antioxidants gets altered with the progression of pregnancy. The present longitudinal study summarized the trend of selected micronutrients level in anaemic (AP) and non-anaemic primigravida (NAP) supplemented with daily and weekly oral iron folic acid (IFA) tablet during pregnancy and postpartum. METHODS: A total of 200 primigravida {N = 100; NAP (Hb > 11 g/dl) and N = 100 AP (Hb = 8-11 g/dl) assigned daily (N = 50) and weekly (N = 50) supplementation} were recruited and overnight fasting blood samples were withdrawn at 13-16 weeks, after 3 months and 6 weeks postpartum. The serum iron, copper, zinc, magnesium and manganese were estimated by inductively coupled plasma-atomic emission spectrophotometer. RESULTS: Serum manganese (p < 0.05) at baseline and magnesium (p < 0.01) at postpartum was significantly different between NAP and AP supplemented with daily IFA tablets. The trend of copper found to be increased during pregnancy and later declined at postpartum in both the groups. Daily supplementation resulted in significantly high iron (p < 0.05) in NAP during third trimester. CONCLUSIONS: Hypozincemia and hypomagnesemia was observed in anaemic pregnancy supplemented with weekly and daily IFA respectively. Clear evidence of altered micronutrients levels during healthy and anaemic pregnancy was seen. The reference values may be drawn from this study for the nutritional assessment during pregnancy for healthy pregnancy outcomes.

Assessment and comparison of pregnancy outcome among anaemic and non anaemic primigravida mothers.

BACKGROUND: Primigravidas (PGs) are high-risk women and anemia in pregnancy is one of the commonest causes of maternal morbidity and mortality. OBJECTIVES: The study was conducted to assess impact of anemia on course and outcome of pregnancy in anemic (Hemoglobin 8-10.9 gm%) and nonanemic PGs. METHODS: This prospective longitudinal study was conducted in All India Institute of Medical Sciences, New Delhi. PGs 20-30 years age, gestation age 16-18 weeks, hemoglobin >8 gm%, live singleton pregnancy, and no other medical illness were recruited after informed consent. The women were Grouped 1 and 2 if hemoglobin was ≥11 gm% and 8-10.9 gm%, respectively. Complete hemogram done at enrollment, 28-30 weeks of pregnancy and 6 weeks postdelivery. Obstetric outcome and presence of anemia postdelivery were compared between groups using Chi-square test and Fisher's exact test. RESULTS: A total of 377 PGs were enrolled and obstetric outcomes studied in 179 (Group 1) and 149 (Group 2) excluding women who did not complete study. There was no statistically significant difference in baseline characteristics, antenatal complications, gestational age, mode of delivery, and neonatal outcome. At 28-30 weeks of gestation, in spite of iron supplementation higher percentage (64.4%) (P < 0.05) of anemic patients remained anemic. At 6 weeks postdelivery, 15.6% and 24.2% were anemic in Group 1 and 2, respectively (P > 0.05). The adverse postpartum events (7.6%) were seen more in anemic compared to nonanemic pregnant women (P < 0.05). CONCLUSIONS: Cautious approach required in postpartum period of anemic women though antenatal period is similar as nonanemic pregnant women.

Randomized Controlled Trial in Advance Stage Breast Cancer Patients for the Effectiveness on Stress Marker and Pain through Sudarshan Kriya and Pranayam.

OBJECTIVE: The objective of this study is to examine the effect of a cognitive, behavioral stress management module of Sudarshan Kriya (SK) and P on levels of serum cortisol and pain among the women suffering from advanced stage breast cancer. MATERIALS AND METHODS: Participants (n = 147) were screened and randomized to receive standard care (n = 69) versus standard along with SK and Pranayam (P) intervention (n = 78) imparted in one 18 hrs workshop spread during 3 days. Participants were expected to practice it at home 20 min daily as adjuvant to standard pharmacological treatment for pain. RESULTS: There was a significant difference in blood cortisol levels after 3 months of practice of SK and P. Mean blood levels in the intervention arm were 341.2 ng/ml against 549.2 ng/ml in the control arm (P ≤ 0.002). Pain perception in comparison to control arm reduced by 3 points in SK and P arm on 0-10 verbal scale of pain. CONCLUSION: SK and P is an effective intervention in reducing stress and pain among advance stage patients of breast cancer.

Need to Bring Family to the Heart of Healthcare as it is Home, not a Hospital, Where Healthcare Begins and Ends.

Today the patients and their families are 'powerless' recipients of healthcare services. The healthcare services are siloed and fragmented and getting worse with an increasing array of specialists and subspecialists who "patch up" patients and send them back home. It is important for healthcare providers to become involved in the process of health promotion, prevention, and recovery. For successful implementation of this family-level care needs to be recognized and integrated into all policies, guidelines of the government, and healthcare providers reoriented through in-service and basic training.

Situational Analysis of Healthcare Delivery and User Perspectives of Mobile Diagnostics (mDiagnostics) in Chennai, Tamil Nadu, India: A Mixed-Method Study.

Introduction Situational analysis of exciting infrastructure including mobile health services is crucial for comprehensive healthcare delivery. The concept of mDiagnostics has gained traction as it addresses the challenges of accessibility, affordability, and availability of healthcare services in remote regions. Purpose The study was to do a situational analysis of the availability of medical diagnostic facilities and identify the challenges and barriers faced in the implementation and utilisation of mDiagnostics. Material and methods The present study was a mixed mixed-method study conducted in rural and urban areas of Chennai, Tamil Nadu, India. A total of 1,489 households were included. Situational analysis of existing healthcare facilities and the availability of Ayushman Bharat Health Account (ABHA) numbers for study participants in both urban and rural areas was assessed. In-depth interviews on user perspective, affordability, awareness of existing health services, and perception of the utility of mobile lab services and focus group discussions with healthcare professionals, community members, and key stakeholders were carried out. Thematic analysis for qualitative data, proportion, and means were calculated for the quantitative component. Result Out of 1,489 households included, 711 were from rural areas, and 778 were from urban areas. The distance traveled from their residence to both the lab and health facility was less than 5 km in urban areas, while it is more than 5 km in rural areas. The mean expenditure in availing healthcare services is above five thousand rupees per annum in nearly half of the rural households (46%) and 60% of urban. The analyses of interviews explored the availability, acceptability, and affordability under seven thematic areas for situational analysis of healthcare facilities, and a focused group discussion was held to explore the community member's barrier to healthcare services. Conclusion The study reveals a comprehensive understanding of healthcare delivery access disparities between rural and urban areas in Tamil Nadu. The findings highlighted the potential benefits of mobile lab initiatives in improving healthcare access and early disease detection in underserved rural communities.

Situational Analysis of Healthcare and Medical Diagnostic Testing Facility Availability in Selected Blocks of Muzaffarpur District, Bihar, India: A Cross-Sectional Study.

INTRODUCTION: This study presents a comprehensive assessment of healthcare facilities, focusing on workforce composition, operational dynamics, diagnostic laboratory services, and accessibility considerations. The comparison between government and private healthcare sectors provides insights into service delivery and potential disparities. The study's rationale, objectives, and methodology are explored in the context of the Indian healthcare landscape. METHODS: A cross-sectional analysis was conducted in Muzaffarpur district, Bihar, targeting selected urban and rural blocks. The study employed geolocation data to analyze accessibility to healthcare facilities. Data collection involved on-site visits, structured questionnaires, and consultation of the Indian Council of Medical Research (ICMR)'s framework. The assessment concentrated on the availability of tests offered by the LaBike platform, and workforce compositions were compared. RESULTS: Government healthcare facilities exhibited a balanced distribution of doctors, nurses, and grassroot workers, reflecting comprehensive healthcare provisions. Private facilities, although featuring moderate doctor and nurse presence, lacked grassroot workers. Diagnostic test prevalence was evident, with core tests, such as CBC and blood glucose, available in over 85% of facilities. Government facilities provided tests free of charge, while private facilities showcased a diverse cost spectrum. Proposed interventions received strong support from both sectors, indicating the potential for innovative healthcare solutions. Accessibility analysis: Urban intervention and control sites demonstrated comparable accessibility, with facilities located within 2 km. In rural intervention and control sites, distances varied significantly. Mushahari, a rural intervention site, required participants to travel 6 km to the nearest facility, impacting healthcare access. By contrast, Marwan, a rural control site, featured a shorter distance of 3 km. CONCLUSION: This study's comprehensive evaluation of healthcare facilities offers valuable insights into workforce dynamics, diagnostic services, and healthcare interventions in the context of government and private sectors. The findings underscore the significance of addressing workforce gaps and promoting equitable access to diagnostics. By informing evidence-based decision-making, this study contributes to the optimization of healthcare service delivery, aiming to enhance healthcare quality and accessibility for all.

Effects of Sudarshan KriyaYoga and Advanced Meditation Program on Genetic Expression of Pro-inflammatory and Antioxidants Genes.

Background Stress leads to immune system dysregulation and dyshomeostasis at the gene level. Mind-body practices are known to influence genomic expression, leading to better health and quality of life. Objective To assess the effect of Advanced Meditation Program (AMP) on the mRNA expression of pro-inflammatory and antioxidative genes among those already practicing Sudarshan Kriya Yoga (SKY). Methods A total of 97 healthy volunteers participated in the study, distributed into two groups. The Group I SKY practitioners attended a four-day AMP (50 participants with an average age of 38.8 ± 11.9 consisting of 37 females and 13 males); they are first-time participants of the AMP. Group II SKY practitioners, on the other hand, consisted of 47 participants with an average age of 36.4 ± 9.3 with 43 females and four males. At day 0, day 5, and day 90, the mRNA expression of pro-inflammatory genes, namely interleukin (IL) 1ß, IL6, and the tumor necrosis factor (TNF), and the expression of antioxidative genes, namely superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPx) was observed. The data were analysed in two phases due to the emergence of coronavirus disease 2019 (COVID-19): (i) pre-COVID-19 and (ii) during COVID-19. Results In the pre-COVID-19 data set, IL1ß, IL6, and TNF were found to have decreased in both groups. There is a significant increase in the expression of SOD and catalase in Group I and a decrease in Group II by day 90. During COVID-19, pro-inflammatory genes increased in Group I and had no significant change in Group II. All three antioxidant genes had decreased expression by day 90 in Group I; SOD decreased in Group II. Interpretation and conclusions Reduced expression of pro-inflammatory genes and increase in the expression of antioxidative genes during the pre-COVID-19 time suggest that the practice of SKY and added AMP may enhance antioxidative defense and may reduce the chance of getting diseases related to inflammation in the body.

Temporal trends of malondialdehyde in stored human plasma.

Malondialdehyde (MDA) is widely used as oxidative stress biomarker in biomedical research. Plasma is stored in deep freezers generally till analysis. Effect of such storage on MDA values, which may be variable and prolong, was incidentally observed in the ongoing study which is to estimate oxidative stress with oral iron. Plasma from blood samples of pregnant women (20-30 years age) in third trimester of singleton pregnancy (n = 139), consuming oral iron tablets was stored at -20 °C with intention of MDA estimation, as soon as possible. However logistic problems led this storage for prolonged and variable period (1-708 days). When values of MDA estimated using "Ohkawa" 79 method and readings were plotted against time to check the temporal effect, it showed a hyperbolic curve. Standard deviation (SD) was lowest when samples were tested within 3 weeks time. The samples analyzed within 3 weeks had mean ± SD value of 31.59 ± 26.11 µmol/L, while 123.7 ± 93.97 and 366.5 ± 189.8 µmol/L for samples stored for 1-3 and 4 months to 1 year respectively. Mean ± SD were 539.9 ± 196.8 in the samples store for more than a year. Rate of change in values was also lowest (0.0433 µmol/L/day) in the samples tested within first 3 weeks, which rose to 1.2 µmol/L/day during 3 month's storage. This rate peaked at storage of 120 days (1.87 µmol/L/day) and fell to 0.502 µmol/L/day in the second year of storage. It is concluded that at -20 °C, only 3 weeks of storage time should be considered valid for fairly acceptable stability in MDA values.

Fine-needle aspiration in suspected inflammatory breast cancer: case series with emphasis on approach to specimen adequacy.

OBJECTIVES: To highlight the utility of a tangential approach in the fine-needle aspiration (FNA) technique for obtaining cellular material adequate for a conclusive diagnosis in diffusely enlarged breast without a discrete lump. STUDY DESIGN: FNA was performed on 5 women clinically suspected to have inflammatory breast cancer (IBC). All had unilateral diffusely enlarged breasts with peau d'orange changes of the skin. No distinct lump was palpable. The procedure was performed using a 10 cm(3) syringe with a tangential approach of a 23-gauge needle in all 4 quadrants with extra passes in the antigravity areas. Rapid on-site evaluation for adequacy was done. RESULTS: All women were of African descent within the age range of 34-57 years. One case had a recent history of lactation. FNA smears showed low-to-moderate cellularity. One case was suspicious and 4 were positive for ductal carcinoma. Core biopsy confirmed IBC in 3 cases. Two cases had a mastectomy; 1 of these cases had preoperative neoadjuvant chemotherapy. CONCLUSION: The approach of FNA used in these cases helped to establish the diagnosis of IBC in 4 women presenting with a diffusely enlarged and tender breast, resulting in the timely initiation of appropriate management. The technique needs to be assessed in a larger cohort of women with diffusely enlarged breast to evaluate its diagnostic utility.
