Psychiatric disorders in older adults with cancer referred to psycho-oncology service in a tertiary care cancer centre: a 7-year real world experience from India.

BACKGROUND: Cancer affects mental health in older adults with cancer (OAC), affecting almost 50% of the patients. There are only a few studies on psychiatric disorders in OAC, especially in low resource settings. We report on our real-world experience of prevalence of and factors associated with psychiatric disorders in OAC referred to a psycho-oncology service in an Indian tertiary care cancer institute. METHODS: We retrospectively analysed medical and psycho-oncology records of patients aged 60 + on cancer-directed treatment or follow-up for < 2 years after treatment completion, referred to psycho-oncology services in a tertiary care cancer centre in Mumbai, India, from Jan 2011-Dec 2017. We recorded sociodemographic, clinical, and treatment-related variables, as well as past psychiatric disorders. The ICD-10 was used to record current psychiatric disorder type and presence. IBM SPSS version 24 (Armonk, NY, USA) was used for descriptive measures, tests of association, and logistic regression analysis. The study protocol was approved by Institutional Ethics Committee and registered with the Clinical Trials Registry-India (CTRI/2020/06/026095). RESULTS: Of 763 patients included in the study, 475 (62.3%) were males and 436 (57.1%) were inpatients, with a median age of 65 years. 93% of the patients had a solid tumour and 207 (27.1%) had a history of psychiatric disorder. A current psychiatric diagnosis was noted in 556 patients (72.9%) on initial presentation, of which adjustment disorders, delirium and depression and anxiety disorders were most frequently seen in 25.2%, 21% and 11.1%, respectively. On univariate analysis, a past history of psychiatric disorders (χ2 = 34.6, p < 0.001), lower performance status (χ2 = 9.9, p = 0.002) and haematolymphoid malignancy (χ2 = 4.08, p = 0.04) significantly increased the risk of current psychiatric diagnosis. Logistic regression confirmed these variables as significant. CONCLUSION: Older adults with cancer referred to psycho-oncology services have high rates of psychiatric disorders at their initial presentation, mainly adjustment disorders, delirium and depression and anxiety. A past history of psychiatric disorders, lower performance status and haematolymphoid cancers significantly increased the risk of psychiatric disorders. Multidisciplinary psycho-oncology teams including a psychiatrist should be integrated in comprehensive care of this group of patients. Further research outcomes and effect of psycho-oncological interventions is required in older adults with cancer in LMIC settings.

Validation of the hospital anxiety depression scale - Marathi version in detecting anxiety and depression in cancer patients and caregivers.

Background: ">The Hospital and Anxiety Depression Scale (HADS) is useful for screening depression and anxiety in cancer. It has not been validated in the Marathi language, which is the third most common language in India. We aimed to examine the reliability and validity of the Marathi-translated version of HADS in cancer patients and their caregivers. Methods: In a cross-sectional study design, we administered the Hospital and Anxiety Depression Scale-Marathi version (HADS-Marathi) to 100 participants (50 patients and 50 caregivers) after obtaining their informed consent. The team Psychiatrist, who was blind to the HADS-Marathi scores, interviewed all participants and identified the presence of anxiety and depressive disorders using the diagnostic criteria of the International Classification of Diseases - 10th edition. We measured internal consistency using Cronbach's alpha, receiver operating characteristics, and factor structure. The study was registered with the Clinical Trials Registry-India (CTRI). Results: The internal consistency of HADS-Marathi was good with 0.815, 0.797, and 0.887 for anxiety and depression subscales and total scale, respectively. The area under curve figures were 0.836 (95% Confidence Interval [CI]: 0.756 - 0.915), 0.835 (95% [CI]: 0.749-0.921), and 0.879 (95% [CI] 0.806-0.951) for anxiety and depression subscales, and total scale, respectively. The best cutoffs identified were 8 (anxiety), 7 (depression), and 15 (total). The scale displayed a three-factor structure, with two depression subscale and one anxiety subscales items loading on to the third factor. Conclusion: We found that the HADS-Marathi version is a reliable and valid instrument for use in cancer patients. However, we found a three-factor structure, possibly reflecting a cross-cultural effect.

International collaboration for assessing unmet needs of cancer survivors and family caregivers: Lens of healthcare professionals.

OBJECTIVE: Cancer patients and their family caregivers have reported various needs that are not met. Recognition of the unmet needs by healthcare professionals may be a first step to adequately and systematically addressing them. Thus, the International Psycho-Oncology Society Survivorship Online Survey was developed to measure healthcare professionals' evaluation about the unmet needs of their patients and family caregivers around the globe. METHODS: The survey was developed in English and translated to additional 14 different languages. The survey was distributed on the web-based REDCap application to over 50 psycho-oncology societies and their networking platforms as well as social media and to authors who have published in psycho-oncology journals globally. RESULTS: A total of 1472 participants from 36 countries at least partially completed the survey. Healthcare professionals evaluated needs for managing one's emotional distress and patients' medical care and symptoms as the most common concerns for both patients and their family caregivers across all patient age groups. Less than two-thirds of the participating healthcare professionals reported that their institution had services or programs to address the needs of the patients or caregivers. CONCLUSIONS: Findings suggest several directions for further analyses to provide more specific information that would be readily translated into clinical practices, research, and policy aimed to enhance the quality of life of cancer patients, survivors, and family caregivers around the globe. In addition, this collaborative effort also hints at the importance of establishing international networks to promote equity in care for people touched by cancer worldwide.

Tolerance mechanisms in maize identified through phenotyping and transcriptome analysis in response to water deficit stress.

Water deficit is a key limiting factor for maize (Zea mays L.) productivity. Elucidating the molecular regulatory networks of stress tolerance is crucial for genetic enhancement of drought tolerance. Two genotypes of maize contrasting in their yield response to water deficit were evaluated for tolerance traits of water relations, net CO2 assimilation rate, antioxidative metabolism and grain yield in relation to the expression levels, based on transcription profiling of genes involved in stress signaling, protein processing and energy metabolism to identify functional tolerance mechanisms. In the genotype SNJ201126 upregulation of calcium mediated signaling, plasma membrane and tonoplast intrinsic proteins and the membrane associated transporters contributed to better maintenance of water relations as evident from the higher relative water content and stomatal conductance at seedling and anthesis stages coupled with robust photosynthetic capacity and antioxidative metabolism. Further the protein folding machinery consisting of calnexin/calreticulin (CNX/CRT) cycle was significantly upregulated only in SNJ201126. While the down regulation of genes involved in photosystems and the enzymes of carbon fixation led to the relative susceptibility of genotype HKI161 in terms of reduced net CO2 assimilation rate, biomass and grain yield. Our results provide new insight into intrinsic functional mechanisms related to tolerance in maize.

Placental growth factor and Fms related tyrosine kinase-1 are hypomethylated in preeclampsia placentae.

Aim: This study aims to examine the DNA methylation (DNAm) and expression patterns of genes associated with placental angiogenesis in preeclampsia. Materials & methods: DNAm and expression were examined in normotensive (n = 100) and preeclampsia (n = 100) women using pyrosequencing and quantitative real-time PCR respectively. Results: Hypomethylation at several CpGs was observed in PlGF and FLT-1 in women with preeclampsia compared to normotensive controls. PlGF expression was lower in women with preeclampsia while FLT-1 expression was comparable. DNAm at various CpGs was negatively correlated with expression in both the genes and were associated with maternal blood pressure and birth outcomes. Conclusion: DNAm and expression of angiogenic factors in placentae are differentially regulated in preeclampsia and influence birth outcomes.

Histochemical and Immunohistochemical Analysis of Collagen Fibers and Microvascular Density in Various Grades of Oral Submucous Fibrosis.

BACKGROUND AND OBJECTIVE: This study was aimed to evaluate the collagen fibers qualitatively and its correlation with microvascular density in various grades of oral submucous fibrosis (OSMF). MATERIAL AND METHODS: The present study comprised of total 40 cases of oral submucous fibrosis. Picrosirius red staining was done on all the specimens' sections. They were analyzed for the colour and orientation of collagen fibers. Morphometric measurements were done using image analysis on immunohistochemical stained sections for Factor VIII-related antigen and analyzed for microvascular density. RESULTS: Picrosirius red polarizing microscopy results revealed that there was a shift in the colour of collagen fibers from greenish yellow to orange red and red colour as the severity of the oral submucous fibrosis increased. The collagen fibers showed mixed orientation in early oral submucous fibrosis and parallel orientation in advanced oral submucous fibrosis. There was a significant decrease in microvascular density from early to advanced oral submucous fibrosis. CONCLUSION: The change in the colours and orientation of collagen fibers in early and advanced oral submucous fibrosis could be attributed to the fibre thickness, type of collagen, alignment and packing, cross-linking of the fibers and the section thickness. However, in advanced cases the vascularity is reduced which may predispose to epithelial atrophy and subsequent malignant changes.

The REVAMP study: research exploring various aspects and mechanisms in preeclampsia: study protocol.

BACKGROUND: Preeclampsia is a major cause of maternal, fetal and neonatal morbidity and mortality, particularly in developing countries. Considering the burden of preeclampsia and its associated complications, it is important to understand the underlying risk factors and mechanisms involved in its etiology. There is considerable interest in the potential for dietary long chain polyunsaturated fatty acids (LCPUFA) as a therapeutic intervention to prevent preeclampsia, as they are involved in angiogenesis, oxidative stress, and inflammatory pathways. METHODS: The REVAMP study (Research Exploring Various Aspects and Mechanisms in Preeclampsia) follows a cohort of pregnant women from early pregnancy until delivery to examine longitudinally the associations of maternal LCPUFA with clinical outcome in preeclampsia. A multisite centre for advanced research was established and pregnant women coming to Bharati hospital and Gupte hospital, Pune, India for their first antenatal visit are recruited and followed up at 11-14 weeks, 18-22 weeks, 26-28 weeks, and at delivery. Their personal, obstetric, clinical, and family history are recorded. Anthropometric measures (height, weight), food frequency questionnaire (FFQ), physical activity, socioeconomic status, fetal ultrasonography, and color Doppler measures are recorded at different time points across gestation. Maternal blood at all time points, cord blood, and placenta at delivery are collected, processed and stored at - 80 °C. The children's anthropometry is assessed serially up to the age of 2 years, when their neurodevelopmental scores will be assessed. DISCUSSION: This study will help in early identification of pregnant women who are at risk of developing preeclampsia. The prospective design of the study for the first time will establish the role of LCPUFA in understanding the underlying biochemical and molecular mechanisms involved in preeclampsia and their association with developmental programming in children.

Inflammation and cancer.

Inflammation is often associated with the development and progression of cancer. The cells responsible for cancer-associated inflammation are genetically stable and thus are not subjected to rapid emergence of drug resistance; therefore, the targeting of inflammation represents an attractive strategy both for cancer prevention and for cancer therapy. Tumor-extrinsic inflammation is caused by many factors, including bacterial and viral infections, autoimmune diseases, obesity, tobacco smoking, asbestos exposure, and excessive alcohol consumption, all of which increase cancer risk and stimulate malignant progression. In contrast, cancer-intrinsic or cancer-elicited inflammation can be triggered by cancer-initiating mutations and can contribute to malignant progression through the recruitment and activation of inflammatory cells. Both extrinsic and intrinsic inflammations can result in immunosuppression, thereby providing a preferred background for tumor development. The current review provides a link between inflammation and cancer development.

Résumé L'inflammation est souvent associée au développement et à la progression du cancer. Les cellules responsables de l'inflammation associée au cancer sont génétiquement stables et ne subissent donc pas l'émergence rapide d'une pharmacorésistance; par conséquent, le ciblage de l'inflammation représente une stratégie attrayante à la fois pour la prévention du cancer et pour le traitement du cancer. L'inflammation tumorale extrinsèque est causée par de nombreux facteurs, notamment: infections bactériennes et virales, maladies auto-immunes, obésité, tabagisme, exposition à l'amiante et consommation excessive d'alcool, le tout qui augmentent le risque de cancer et stimulent la progression maligne. En revanche, l'inflammation intrinsèque au cancer ou provoquée par le cancer peut être déclenchée par des mutations initiant un cancer et peuvent contribuer à la progression maligne par le recrutement et l'activation de cellules inflammatoires. Tous les deux les inflammations extrinsèques et intrinsèques peuvent entraîner une immunosuppression, fournissant ainsi un fond préféré pour le développement de la tumeur. le l'examen actuel établit un lien entre l'inflammation et le développement du cancer.

Matrix metalloproteinases-2 (MMP-2) and matrix metalloproteinases -9 (MMP-9) are differentially expressed in different regions of normal and preeclampsia placentae.

Matrix metalloproteinases (MMPs) are involved in the extracellular matrix (ECM) remodeling during human placentation and parturition and have been shown to be associated with oxidative stress. Placental regional changes in oxygen availability and oxidative stress indices may influence regional differences in expression of MMPs. This study examines the protein and mRNA levels of MMP-2 and MMP-9 in different regions of the placenta in normotensive control (NC) women and women with preeclampsia (PE). Fifty-two NC women and 43 women with PE (18 delivered at term [T-PE] and 25 delivered preterm [PT-PE]) were recruited. Placental samples were taken from four regions: central basal (CM), central chorionic (CF), peripheral basal (PM), and peripheral chorionic (PF). MMP protein and mRNA levels were measured by ELISA and quantitative real time PCR, respectively. MMP-2 protein levels were higher in all the placental regions (P < 0.05) from PT-PE group as compared to the respective regions from the NC and T-PE groups. MMP-9 mRNA levels were higher in CM region as compared to CF and PM regions (P < 0.05) in the NC group and compared to CF and PF regions (P < 0.05) in the T-PE group. The MMP-9 mRNA levels were lower in the CF region in the PT-PE and T-PE groups (P < 0.05) as compared to the NC group. Elevated levels of MMP-2 protein levels were observed in all regions of PT-PE placenta possibly influencing the degradation of placental ECM. Lower mRNA expression of MMP-9 both in PT-PE and T-PE may contribute to a disturbed placental vascularization.

VEGF and VEGFR1 levels in different regions of the normal and preeclampsia placentae.

Altered placental angiogenesis is implicated in the pathophysiology of preeclampsia. We have earlier reported placental regional differences in oxidative stress markers and neurotrophins. Oxidative stress and neurotrophins are reported to regulate angiogenesis. This study aims to examine protein and mRNA levels of vascular endothelial growth factor (VEGF) and VEGF receptor 1 (VEGFR1) in four regions [central maternal (CM), central fetal (CF), peripheral maternal (PM), and peripheral fetal (PF)] of the placenta in normotensive control (NC) women (n = 51) and women with preeclampsia (PE) (n = 43) [18 delivered at term (T-PE) and 25 delivered preterm (PT-PE)]. In all groups, CF region reported highest VEGF protein levels compared to all other regions. VEGF mRNA level was higher in CF region as compared to CM region in PE group (p < 0.05). VEGF levels were lower in all regions of PE, T-PE, and PT-PE groups (p < 0.05) as compared to their respective regions in NC group. VEGFR1 levels were lower in CF (p < 0.05) and PF (p < 0.01) regions as compared to CM region only in control. However, VEGFR1 levels were higher in CF (p < 0.05) and PF (p < 0.01) regions of PT-PE group as compared to control. VEGFR1 mRNA level was higher in PM region of PE group and T-PE group (p < 0.05 for both) as compared to control. VEGF levels in the PF region were positively associated with birth weight and placental weight. This study describes placental regional changes in angiogenic factors particularly highlighting increased VEGF in CF region possibly in response to hypoxic conditions prevailing in placenta.

Differential accumulation of vimentin fragments in preeclamptic placenta.

Preeclampsia is a pregnancy complication that is the result of abnormal placentation because of inadequate trophoblast invasion into spiral arteries that prevent normal blood flow to the placenta. We report the alteration in vimentin protein proteolysis in placenta of normotensive and preeclamptic women, which is known to have a role in many physiological functions other than its major function in the structural integrity of the cell. Placental proteome from normotensive (n = 25) and preeclamptic pregnancies (n = 25) showed eight differentially accumulated protein spots of vimentin (proteolytic fragments) by two-dimensional electrophoresis. Immunoblots of normotensive and preeclamptic placenta revealed a difference in proteolytic processing of vimentin. In particular, lower molecular weight vimentin fragments of 32 and 20 kDa were 3.3 and 2.6-fold (p < 0.0001) higher, respectively, in preeclampsia compared with normotensive placenta.

Hypermethylated CpG sites in the MTR gene promoter in preterm placenta.

AIM: Altered maternal one-carbon metabolism influences placental DNA methylation patterns and 'programs' the fetus for noncommunicable diseases in adult life. EXPERIMENTAL PROCEDURES: Levels of plasma folate, vitamin B12, homocysteine, mRNA and protein levels of MTHFR and MTR enzymes in placenta were compared among women delivering preterm (n = 83) and term (n = 75). MTR promoter CpG methylation was undertaken. RESULTS: MTHFR and MTR mRNA levels were higher while protein levels were lower, and MTR CpG sites were hypermethylated in the preterm group, as compared with the term group. Methylated CpG sites were negatively associated with maternal plasma vitamin B12 levels. CONCLUSION: Study suggests a dysregulation of enzyme genes in remethylation arm of the one-carbon metabolism in placenta of women delivering preterm.

Tubulointerstitial nephritis antigen-like 1 protein is downregulated in the placenta of pre-eclamptic women.

BACKGROUND: Tubulointerstitial nephritis antigen-like 1 protein (TINAGL1), is a matricellular protein, known to play role in cell adhesion and cell receptor interaction. Research related to TINAGL1 is limited to cell culture and animal models. Demonstration of TINAGL1 as a positive regulator of angiogenesis and its expression in the decidua of postimplantation mouse uterus, prompted us to validate its expression in human placenta during impaired angiogenesis in pre-eclamptic condition. METHODS: Placental tissue from normotensive (n = 25) and pre-eclamptic (n = 25) pregnancies were used to study the differentially expressed proteins by two-dimensional gel electrophoresis and TINAGL1 protein was validated with Western blotting. RESULTS: A total of 55 protein spots were differentially expressed (fold change >1.5, p < 0.05), of which 27 were upregulated and 28 were downregulated in the pre-eclamptic placenta. TINAGL1 was found to be downregulated in pre-eclamptic compared to normotensive pregnant women. CONCLUSION: This is the first study reporting TINAGL1 to be present in human placenta and differentially expressed in pre-eclamptic condition. The functional role of TINAGL1 in association to human pregnancy needs to be explored further.

Placental Proteomics Provides Insights into Pathophysiology of Pre-Eclampsia and Predicts Possible Markers in Plasma.

Pre-eclampsia is a hypertensive disorder characterized by the new onset of hypertension >140/90 mmHg and proteinuria after the 20th week of gestation. The disorder is multifactorial and originates with abnormal placentation. Comparison of the placental proteome of normotensive (n = 25) and pre-eclamptic (n = 25) patients by gel-free proteomic techniques identified a total of 2145 proteins in the placenta of which 180 were differentially expressed (>1.3 fold, p < 0.05). Gene ontology enrichment analysis of biological process suggested that the differentially expressed proteins belonged to various physiological processes such as angiogenesis, apoptosis, oxidative stress, hypoxia, and placental development, which are implicated in the pathophysiology of pre-eclampsia. Some of the differentially expressed proteins were monitored in the plasma by multiple reaction monitoring analysis, which showed an increase in apolipoproteins A-I and A-II in gestational weeks 26-30 (2-fold, p < 0.01), while haptoglobin and hemopexin decreased in gestational weeks 26-30 and week 40/at delivery (1.8 fold, p < 0.01) in pre-eclamptic patients. This study provides a proteomic insight into the pathophysiology of pre-eclampsia. Identified candidate proteins can be evaluated further for the development of potential biomarkers associated with pre-eclampsia pathogenesis.

Utility of squash smear cytology in intraoperative diagnosis of central nervous system tumors.

BACKGROUND: Central nervous system (CNS) squash cytology (CSC) has established itself as a technically simple, rapid, inexpensive, fairly accurate, and dependable intraoperative diagnostic tool. It helps neurosurgeons immensely when management is dependent on it. AIMS: This study aimed at finding out the utility of CSC as an intraoperative diagnostic tool from a neurosurgeon's perspective. MATERIALS AND METHODS: Fifty prospectively registered patients with clinical diagnosis of CNS tumors were enrolled in the study. All the patients were subjected to magnetic resonance imaging (MRI). Intraoperative CSC was performed and smears were stained with Leishman and rapid Hematoxylin and Eosin (H and E) stain. The diagnosis of CSC was compared with MRI diagnosis and histopathological diagnosis. The CNS tumors were categorized based on clinical and therapeutic implications. Diagnostic accuracy, sensitivity, specificity, and positive and negative predictive value of MRI and CSC were calculated by using appropriate formulae. RESULTS AND CONCLUSIONS: The age range of the CNS tumors included in the study was 2 to 68 years. There was a slight female preponderance. Sensitivity, specificity, positive predictive value, and negative predictive value of preoperative MRI were 90.47%, 82.76%, 79.17%, and 92.31% respectively. These values of utility parameters for CSC were 100% for each of the clinical and therapeutic implications. It helped neurosurgeons in optimizing surgical procedure in 12 cases of meningioma. It influenced surgical management in 1 case of infratentorial pilocytic astrocytoma, and helped in the diagnosis and management of 9 unexpected tumors missed on MRI.

Reduced Maternal Erythrocyte Long Chain Polyunsaturated Fatty Acids Exist in Early Pregnancy in Preeclampsia.

The present prospective study examines proportions of maternal erythrocyte fatty acids across gestation and their association with cord erythrocyte fatty acids in normotensive control (NC) and preeclamptic pregnancies. We hypothesize that maternal fatty acid status in early pregnancy influences fetal fatty acid stores in preeclampsia. 137 NC women and 58 women with preeclampsia were included in this study. Maternal blood was collected at 3 time points during pregnancy (16-20th weeks, 26-30th weeks and at delivery). Cord blood was collected at delivery. Fatty acids were analyzed using gas chromatography. The proportions of maternal erythrocyte α-linolenic acid, docosahexaenoic acid, nervonic acid, and monounsaturated fatty acids (MUFA) (p < 0.05 for all) were lower while total n-6 fatty acids were higher (p < 0.05) at 16-20th weeks of gestation in preeclampsia as compared with NC. Cord 18:3n-3, 22:6n-3, 24:1n-9, MUFA, and total n-3 fatty acids (p < 0.05 for all) were also lower in preeclampsia as compared with NC. A positive association was observed between maternal erythrocyte 22:6n-3 and 24:1n-9 at 16-20th weeks with the same fatty acids in cord erythrocytes (p < 0.05 for both) in preeclampsia. Our study for the first time indicates alteration in maternal erythrocyte fatty acids at 16th weeks of gestation which is further reflected in cord erythrocytes at delivery in preeclampsia.

Increased homocysteine levels exist in women with preeclampsia from early pregnancy.

OBJECTIVE: The present prospective study examines the levels of maternal plasma folate, vitamin B12 and homocysteine in normotensive control (NC) women and women with preeclampsia (PE) from early pregnancy till delivery. METHODS: The present study includes 126 NC and 62 PE women. Maternal blood was collected at 3 time points during pregnancy (T1 = 16th-20th weeks, T2 = 26th-30th weeks and T3 = at delivery). Levels of folate, vitamin B12 and homocysteine were estimated by the chemiluminescent microparticle immunoassay technology. RESULTS: Maternal plasma folate levels were similar between NC and PE women at all the time points across gestation. Maternal plasma vitamin B12 levels were significantly higher in PE (p < 0.05) as compared with NC at T2. Maternal plasma homocysteine levels were higher in PE as compared with NC at all the time points, i.e. T1, T2 (p < 0.05 for both) and T3 (p < 0.01). CONCLUSION: Our results indicate that higher homocysteine levels exist in women with PE from early pregnancy and continue till delivery.

Regional differences in the placental levels of oxidative stress markers in pre-eclampsia.

OBJECTIVE: To examine placental malondialdehyde (MDA), catalase, and glutathione peroxidase (GPx) levels in four placental regions among women with and without pre-eclampsia. METHODS: A cross-sectional study was conducted among women aged 18-35 years with a singleton pregnancy in Pune, India, between May 3, 2013, and June 16, 2014. Three groups were enrolled: normotensive; pre-eclampsia, delivered at term; and pre-eclampsia, delivered preterm. Samples were collected from the central and peripheral placental regions (maternal and fetal sides) immediately after delivery. RESULTS: A total of 60 women were enrolled (35 normotensive; 11 with pre-eclampsia delivered at term; 14 with pre-eclampsia, delivered preterm). MDA levels were higher in all regions of the placenta among the pre-eclampsia versus normotensive groups (P<0.01). MDA levels were higher in the central maternal region than in the central fetal region in the preterm pre-eclampsia group (P=0.023). The MDA levels in the central maternal region were also higher in the preterm than in the term pre-eclampsia group (P=0.014). Catalase activity was lower in the peripheral maternal (P=0.036) and fetal (P=0.050) regions in the preterm pre-eclampsia group versus the normotensive group. The activity of GPx was higher in the peripheral maternal region than in the central fetal region in the normotensive group (P=0.033). CONCLUSION: Pre-eclampsia might be characterized by differential placental oxidative stress and antioxidant enzyme activity.

A prospective study of maternal fatty acids, micronutrients and homocysteine and their association with birth outcome.

Our earlier studies both in animals and in humans have indicated that micronutrients (folic acid, vitamin B12) and long-chain polyunsaturated fatty acids, especially docosahexaenoic acid (DHA), are interlinked in the one-carbon cycle, which plays an important role in fetal 'programming' of adult diseases. The present study examines the levels of maternal and cord plasma fatty acids, maternal folate, vitamin B12 and homocysteine in healthy mothers at various time points during pregnancy and also examine an association between them. A longitudinal study of 106 normal pregnant women was carried out, and maternal blood was collected at three time points, viz., T1 = 16-20th week, T2 = 26-30th week and T3 = at delivery. Cord blood was collected at delivery. Fatty acids were estimated using a gas chromatograph. Levels of folate, vitamin B12 and homocysteine were estimated by the chemiluminescent microparticle immunoassay (CMIA) technology. Maternal plasma folate (P < 0.05), vitamin B12 (P < 0.01) and DHA (P < 0.05) levels were lowest, while maternal homocysteine levels were highest (P < 0.01) at T3. There was a negative association between maternal DHA and homocysteine at T2 (P < 0.05) and T3 (P < 0.01). There was a positive association between plasma DHA in maternal blood at T3 and cord blood. Furthermore, there was a positive association between maternal folate and vitamin B12 at T3 and baby weight, whereas maternal homocysteine at T1 were inversely associated with baby weight at delivery. Our study provides evidence for the associations of folic acid, vitamin B12, homocysteine with DHA and baby weight, suggesting that a balanced dietary supplementation of folate-vitamin B12-DHA during pregnancy may be beneficial.

Management of Vyanga (facial melanosis) with Arjuna Twak Lepa and Panchanimba Churna.

BACKGROUND: Vyanga is one of the Kshudraroga, characterized by the presence of Niruja (painless) and Shavavarna Mandalas (bluish-black patches) on face. It is one of the most common diseases as regards the face is concerned. On the basis of clinical features, it can be compared with facial melanosis, one of the hyper pigmented disorders. Drugs with Rakta Prasadaka, Twak Prasadaka and Varnyakara properties are helpful in the management of Vyanga, that pacifies aggregated Doshas and help in Raktashodhana (blood purification). AIM: To evaluate the efficacy of Arjunatwak Lepa and Panchanimba Churna in Vyanga. MATERIALS AND METHODS: In this study, the trial drugs used were Arjunatwak Churna for Lepa (tropical application) and Panchanimba Churna for oral administration. A total 30 patients of Vyanga were selected from outpatient department and inpatient department of Shalakya Tantra Department and allotted randomly in two groups. In group-A, the patients were treated with external application of Arjunatwak Churna and Madhu for 21 days, while in group-B, patients received Panchanimba Churna orally for 21 days in addition to Arjunatwak Churna for Lepa. Effect of therapy on chief complaint i.e., bluish-black pigmentation in Group A was 60% relief, while in Group B 80% relief was found. CONCLUSION: The clinical study has shown that combined therapy gives better results than topical treatment.
