RESUMO

Twenty five percent of pregnant women have some degree of vaginal bleeding during the first trimester, and about 50% of those pregnancies end in spontaneous abortion (SA) because the fetus is not developing typically. As studies have reported that inadequacies of trace metals such as Copper (Cu), Zinc (Zn), Magnesium (Mg) can predispose to various adverse pregnancy outcomes (PO); multiple micronutrient (MMN) supplementations are given without justifying their deficiency and toxicities on the fetus. Earlier studies on effects of MMN supplementations during pregnancy have not considered the need, duration, dose, and time of initiation of supplementations leading to inconclusive results. So, there is a need to optimize this to prevent their abuse and side effects. This study can help in establishing critical cut-offs of these minerals in maternal serum that can forecast future pregnancy outcomes. Study measured the serum Zn, Cu, Mg, and Fe in pregnant women who presented with (n = 80) and without (n = 100) SA at 5-2 weeks of pregnancy using iron -ferrozine method, magnesium-calmagite method, zinc reaction with nitro-PAPS, copper reaction with Di-Br- PAESA methods, respectively. Data analyzed using the student t test and cutoff value was established using Receiver Operating Characteristic (ROC) by SPSS software. Maternal serum Cu, Mg, Fe, and Zn levels measured were significantly lower in SA as compared to that of controls (p < 0.005) (Fig. 1) and maternal age and Body mass index were not statistically significant different among study group. Maternal serum Cu, Mg, Zn and Iron (Fe) measured in 5-12 weeks of pregnancy has the potential to forecast future occurrence of SA. The study has been registered under "The Clinical Trials Registry- India (CTRI)," -REF/2020/01/030393.

RESUMO

About 10 to 20% of reported pregnancies have complications like spontaneous abortion (SA), preeclampsia (PE), preterm birth (PTB), and fetal growth restriction (FGR); 60% are attributed to maternal nutritional alterations. Multiple micronutrients (MMN) are supplemented in the antenatal period, but no proper validation/guidelines are available regarding dosing/time, the need for initiation, and the duration of supplementation. Studies have reported adverse pregnancy complications related to the overuse/unwanted use of multiple micronutrient supplementations during pregnancy. Identifying the exact population requiring supplementation is necessary to prevent its abuse. This article attempts to review the impacts of micronutrient deficiency/supplementation in cases of SA, FGR, and gestational diabetes mellitus (GDM), preterm delivery and PE. The study used a literature search using PubMed, Google Scholar, Mendeley, and Scopus Databases using search words pregnancy, spontaneous abortion, gestational diabetes mellitus (GDM), fetal growth restriction (FGR), preterm delivery, preeclampsia (PE) or "adverse pregnancy" associated with minerals, micronutrients, or supplementation. The review also considered in-house literature databases, a single-window search at Kasturba Medical College (KMC) Health sciences library, MAHE (Manipal Academy of Higher Education). The figures included in the study were created by Biorender.com. Micronutrients play multiple roles during pregnancy and fetoplacental growth stimulating growth hormone secretion, Lysyl oxidase (LOX), involved in the crosslinking between collagen and elastin in the amniotic membrane, downregulation of interleukin (IL)-1 alpha, IL-1 beta, IL-4, IL-6, Il-10, IL-12, tumor necrosis factor (TNF)-alpha and several chemokines involved in hypertension, immune-inflammatory pathways, attenuate insulin resistance, structural development of neurons and glia. Over-supplementation has led to complications such as spontaneous abortion and gestational diabetes mellitus. Since there is a lack of standardization concerning micronutrient supplementation during pregnancy, there is a need for systematic study related to the role of micronutrients during each trimester of pregnancy to optimize its supplementation and to prevent hazards associated with its abuse.

RESUMO

BACKGROUND: A one-month long foundation course has been introduced at the entry-level for first-year MBBS (Bachelor of Medicine and Bachelor of Surgery) students in the medical institutions across India from 2019. Therefore, the present study is aimed at describing the experience of implementing a one-month long foundation course conducted for the Competency-based Undergraduate Medical Curriculum (CBUC) of Indian Medical Graduate as per the guidelines from the National Medical Commission (NMC) (erstwhile Medical Council of India, MCI). We have evaluated the student and faculty perceptions towards the effectiveness of the program. METHODS: The foundation course had six modules Orientation, Skills, Field visit to Community Health Centre, Professional Development including Ethics, Sports and Extracurricular activities, Computer Skills, and Language enhancement program. Regular feedback wascollected from students (N = 250) and teachers (N = 26) involved in the Foundation course using a semi-structured questionnaire. The program's overall feedback was also obtained at the end of the course, using a validated questionnaire. The quantitative findings were expressed in frequency and percentage. The qualitative observations (reflections of students and faculty) were subjected to thematic. RESULTS: The students and faculty appreciated the one-month long foundation course. The course's defined objectives were met as indicated by most students (98.4%) and faculty (75%). The course seemed to be useful for students to embark on a formal MBBS curriculum. It also exposed them to new knowledge and practices, as indicated by the feedback. Thematic analysis of the students' and faculty's reflections was carried out and two themes were identified, i.e., 'strengths' and 'challenges.' The Foundation Course Committee will work out appropriate remedial measures to overcome the challenges in the future sessions for subsequent batches. CONCLUSIONS: The one-month-long foundation course was found to be beneficial for newly joined students to get introduced and adjusted to higher education systems' demands. Also, the challenges faced during the program needs to be addressed with suitable remedial measures while implementing for subsequent batches. This effort will ensure a smooth conduct of the foundation course for the future batches of medical undergraduates and make the program more effective.

RESUMO

Background: Neovascularization in the retina and hyperglycaemia-induced oxidative stress are implicated in the pathogenesis of diabetic retinopathy (DR). In this study, we hypothesized that the plasma angiogenic and oxidative stress markers associated with these derangements could aid in the screening of diabetic patients who are at an increased risk of developing retinopathy.Methods: This study included normal (n = 148), type2 diabetes without retinopathy (DNR; n = 148), proliferative DR (PDR; n = 74) and non-PDR (NPDR; n = 148) subjects. Plasma concentrations of vascular endothelial growth factor-A (VEGF-A), hypoxia-inducible factor-1α (HIF-1α), matrix metalloproteinase-9 (MMP-9), pigment epithelium-derived factor (PEDF), nitric oxide (NO), soluble receptors for advanced glycation end products (sRAGE), malondialdehyde (MDA) and protein thiols were estimated.Results: A statistically significant increase was observed in the plasma concentrations of pro-angiogenic factors and markers of oxidative stress in both retinopathy groups. By contrast, the concentrations of anti-angiogenic factors and antioxidants were decreased significantly in these groups. Receiver operating characteristic analysis indicated that the plasma thresholds of HIF-1α and PEDF can be suitable markers in case of NPDR. However, in PDR, HIF-1α, NO, MMP-9 and PEDF showed high sensitivity and specificity.Conclusions: The factors associated with hypoxia, matrix degradation and angiogenic inhibition play a crucial role in predicting DR.

RESUMO

CONTEXT: Even though, a large number of serological, molecular markers have been proposed for breast cancer screening, most of them lack specificity, sensitivity, prognostic value, and cost effectiveness. Butyrylcholinesterase (BChE) and its genes are aberrantly expressed in a variety of human cancers. It has-been linked to tumorigenesis, cell proliferation, and cell differentiation. Zinc (Zn) is a cofactor for superoxide dismutase, an enzyme that protects cellular components against free radical-induced damage and carcinogenesis. Therefore, the aim of present study was to estimate and compare serum BChE and serum Zn levels in healthy controls and biopsy proven breast cancer patients before definitive therapy. AIMS: To estimate and compare serum BChE and serum Zn levels in healthy controls and biopsy proven breast cancer patients before definitive therapy. SETTINGS AND DESIGN: Serum BChE and Zn were estimated in 46 newly diagnosed (preoperative) female patients with breast cancer and 50 healthy female volunteers. SUBJECTS AND METHODS: Serum BChE and Zn were estimated by spectrophotometric method. STATISTICAL ANALYSIS USED: Data was expressed as median and inter quartile range. Comparisons between different stages of cancer were done using Kruskal-Wallis test. RESULTS: There was a significant increase in serum BChE and Zn in breast cancer patients compared to controls (P < 0.001). Serum BChE showed a significant increase and Zn was significantly decreased in different stages of breast cancer. CONCLUSIONS: Both BChE and Zn are inexpensive and can easily be analyzed and may play a role in the management of breast cancer.

RESUMO

Bisalbuminemia is a rarely encountered anomaly characterized by presence of bifid albumin bands or a single widened albumin band in electrophoretogram. Inherited bisalbuminemia is quite rare and inherited as an autosomal dominant form. The acquired form of bisalbuminemia is usually transient and may be observed during long term beta lactam antibiotic therapy, acute pancreatitis, myeloma and nephrotic syndrome. This is a case of bisalbuminemia in 61-year-old diabetic female with hypothyroidism came with acute exacerbation of bronchial asthma.

RESUMO

Oral squamous cell carcinoma is one of the most common malignancies recognized. Biomarkers which can predict presence of cancer and its progression can help in better management of these disorders. Over production of lipid peroxidation byproducts and disturbances in antioxidant defense system have been implicated in the pathogenesis of several diseases including oral cancer. Studies have shown a correlation of butyrylcholinesterase (BChE), with tumourigenesis, cell proliferation and cell differentiation. Earlier we have observed a significant elevation in plasma BChE and protein thiols in oral cancer patients which correlated well with stages of cancer. As it was not clear whether the above markers will be altered in saliva of oral cancer patients this study was undertaken. Institutional Ethics Committee gave permission to carry out this study. Total of 55 subjects comprising healthy controls (n = 30) and biopsy proven oral cancer patients (n = 25) consented to participate in this study. Salivary samples from cases were taken before any definitive treatment. Protein thiols and BChE were estimated in salivary samples using validated assay methods. Oral cancer patients had a significant increase in pre-treatment salivary BChE levels (p ≤ 0.001) and a significant decrease (p ≤ 0.001) in salivary thiols as compared to respective values in controls. Salivary protein thiols and BChE may have a role in pathophysiology of oral cancer. Saliva can be used as a potential non-invasive screening tool in oral cancer patients.

RESUMO

BACKGROUND: The role of oxidative stress in the genesis of various types of cancers is well established. Several chemical, cell culture and animal studies also indicate that antioxidants may slow or even prevent the development of cancer. Brain is considered abnormally sensitive to oxidative damage as brain tissue has high rate of oxygen consumption, high lipid content and relatively low antioxidant defenses, compared to other tissues. MATERIALS AND METHODS: The study design chosen for the present study was cross sectional. The biochemical parameters that were estimated in saliva manually using spectrophotometric methods were ferric reducing antioxidant power (FRAP) assay--a direct measure of total antioxidant activity of biological fluids and protein thiols. The physical parameters of saliva that were also assessed were salivary flow rate, pH of the saliva and the osmolality of the saliva. RESULTS: The mean values of salivary flow rate and pH were significantly decreased among malignant and benign tumor patients whereas the salivary osmolality was significantly increased in both the groups of patients. The mean values of salivary FRAP were significantly reduced among malignant and benign tumor patients. However, the salivary protein thiols were significantly increased in these patients. CONCLUSION: Hence with these observations it can be concluded that in saliva, besides the physical characteristics, salivary FRAP and protein thiol levels are appropriate indicators of the antioxidant status in brain tumor patients.

RESUMO

We conducted a study wherein serum total glutathione-s-transferase levels were measured in patients (n = 27) with various stages of biopsy proven oral cancer (squamous cell carcinoma) and age and sex matched healthy human volunteers (n=10). In all patients with oral cancer, serum total glutathione-s-transferase was measured before the onset of treatment. There was a significant increase in serum total glutathione-s-transferase levels in patients with stage IV oral cancer as compared to stage II (P = 0.001) and stage III (P = 0.002) oral cancer. This shows that alterations in serum total Glutathione-s-transferase levels may have a role in cancer progression.

RESUMO

We conducted a pilot study wherein serum Glutathione-S-transferase levels were measured before and after radiotherapy in carcinoma cervix patients and correlated with response to treatment during a two-year follow-up period. Out of 17 patients who received radiotherapy, 9 showed a significant decrease (p<0.005) while 8 showed significant increase (p<0.004) in post radiotherapy glutathione-S-transferase values as compared to pre treatment values respectively. These patients were followed up for two years and we observed that 71% who had significant increase in post radiotherapy values had relapse of cancer within 2 years where as 66% of those who had significant decrease in post radiotherapy values had no evidence of relapse. This shows that alterations in serum Glutathione-S-transferase levels may help us to predict radiation response.
