An exploratory study using the OMI scale to assess the opinion toward mental illness among young adults

Background: Public perception of mental illness is critical for successful treatment seeking behaviour as well as for early diagnosis and surveillance of disease. Two hundred eleven young patients were interviewed at Department of psychiatry, Sir Sunderlal Hospital, Varanasi with the help of consecutive sampling method. Objective: To assess the opinion towards mental illness among young adults by using the opinion on mental illness scale (OMI). Methods: Data was collected using the opinion about mental illness scale (OMI) which consists of 51 questions out of which, 15 questions directly related to the cause, care, and management of mental illness were randomly selected and analyzed. Analysis was done showing Percentage and chisquare tests to see the significance of scores between the respondents. Results: The finding shows that more than 70% of respondents believe that mental illness is a consequence of bad behavior, lack of willpower, or negative beliefs and gap in the treatment seeking behavior and understanding the cause of disease was found. Conclusions: Opinions on Mental health have received increasing attention as a useful strategy to promote early identification of mental illness, reduce stigma and enhance help-seeking behaviors. As part of the National Mental Health Programme, there is a need to raise awareness in order to enhance understanding of mental illness in facilitating early diagnosis and treatment of disease.

Why road safety is the need of the hour? A study among youth of District Dehradun, Uttarakhand

Background: Road traffic injuries are the eighth leading cause of death globally, and the leading cause of death for young people aged 15–29 years. Each year, almost 400,000 young people under 25 years old are killed in a road traffic crash - about 1049 youngsters every day. Aims and objectives: To find out the prevalence of road safety related health risk behaviours and its determinants amongst young males of District Dehradun. Methodology: It was a cross sectional study conducted over 12 months of duration. The study sample comprised of 1800 male youth aged 15-24years studying in various schools and colleges of District Dehradun. A pre-tested and pre-structured questionnaire (YRBSS) was used. The data was entered and analysed using SPSS-version 20.0. Results: Approximately three-fourth of youth reported never using seat-belt while driving and only 4.4% reported always using helmet whereas 24.0% accepted never use of helmet. Approximately one-fourth of the total 1168 at risk subjects in past 30 days, accepted driving a vehicle while drunk and 39.9% reported use of mobile phones while driving. Personality traits (extrovert, neuroticism and lack of direction) turned out to be the major factor in road safety related health risk behaviour. Conclusion: Although, road safety related health risk was found to be more among urban youth as compared to their rural counterparts, yet it was found alarmingly high for both rural and urban study population.

Sexual Risk Behavior: A Perilous Journey By Unmarried Youth Of District Dehradun, Uttarakhand

Background: Sexual health is an integral part of overall health and well-being and determination of sexuality of the youth is an important milestone in understanding their behavior, associated risks and outcomes. The declining age at puberty and increasing age at marriage has created a longer growing period in which youth may engage in sexual health risk behaviors. This research focuses attention on estimation and involvement of the most dynamic & valuable segment of a nation’s population towards sexual risk behaviors. Aims & objectives: The aim of this study is to find out the prevalence and determinants of sexual health risk behaviors amongst youth in District Dehradun. Material and methods: It was a cross-sectional study conducted over a period of 06 months in rural and urban area of District Dehradun. The study surveyed 1800 male youth aged 15-24 years using a self-administered questionnaire (YRBSS & Big five inventory). After collection, the data was entered using the SPSS software and analyzed using SPSS and Microsoft Excel 2010. Results: Out of 1800 participants, 19% were found to be at risk of sexual health risk behavior and reported having had sex. Out of these 342 at-risk, 43.5% accepted involving in sexual activity even before adulthood, 31% reported having multiple sexual partners and 21.1% accepted not using condoms. Place of residence and personality trait were found to be important determinants of sexual health risk behaviors. Conclusion: Our study documented the high prevalence of sexual risk behavior among male youth of rural and urban area of District Dehradun.

Sleep and Stroke.

Circadian variations in conjunction with sleep-related heart rhythm changes and sleep disordered breathing (SDB) are contributing risk factors for stroke. Strong scientific evidence now exists indicating that SDB contributes to systemic hypertension, a prominent risk factor for stroke, and compelling circumstantial evidence is present suggesting that SDB raises the risk for development of stroke through other circulatory mechanisms as well. Preliminary evidence indicates that post-stroke patients have a higher prevalence of SDB, which is likely to compromise their rehabilitation outcomes. Since SDB is modifiable with the application of CPAP and other treatment modalities, there is practical value in investigating patients at risk of stroke or post stroke for presence of SDB. Successful application of CPAP or BiPAP therapy may improve the outcome in both instances.

Autologous intravenous bone marrow mononuclear cell therapy for patients with subacute ischaemic stroke: a pilot study.

Background & objectives: Bone marrow mononuclear cell therapy has emerged as one of the option for the treatment of Stroke. Several preclinical studies have shown that the treatment with mononuclear cell (MNCs) can reduce the infarct size and improve the functional outcome. We evaluated the feasibility, safety and clinical outcome of administering bone marrow mononuclear cell (MNCs) intravenously to patients with subacute ischaemic stroke. Methods: In a non-randomized phase-I clinical study, 11 consecutive, eligible and consenting patients, aged 30-70 yr with ischaemic stroke involving anterior circulation within 7 to 30 days of onset of stroke were included. Bone marrow was aspirated from iliac crest and the harvested mononuclear cells were infused into antecubital vein. Outcomes measured for safety included immediate reactions after cell infusion and evidence of tumour formation at one year in whole body PET scan. Patients were followed at week 1, 4-6, 24 and 52 to determine clinical progress using National Institute of Health Stroke Scale (NIHSS), Barthel Index (BI), modified Rankin Scale (mRS), MRI, EEG and PET. Feasibility outcomes included target-dose feasibility. Favourable clinical outcome was defined as mRS score of 2 or less or BI score of 75 to 100 at six months after stem cell therapy. Results: Between September 2006 and April 2007, 11 patients were infused with bone-marrow mononuclear cells (mean 80 million with CD-34+ mean 0.92 million). Protocol was target-dose feasible in 9 patients (82%). FDG-PET scan at 24 and 52 wk in nine patients did not reveal evidence of tumour formation. Seven patients had favourable clinical outcome. Interpretation & conclusions: Intravenous bone marrow mononuclear cell therapy appears feasible and safe in patients with subacute ischaemic stroke. Further, a randomized controlled trial to examine its efficacy is being conducted.

IgG subclass responses to proinflammatory fraction of Brugia malayi in human filariasis.

Background & objectives: Earlier we demonstrated that immunization with F6, a proinflammatory molecular fraction isolated from the human filarial parasite Brugia malayi, protected the host and eliminated the infection in Mastomys coucha by a Th1/Th2 response including IgG2a antibody response. Whether F6 molecules become accessible to human host during natural course of infection and elicit similar response is not known. The present study was undertaken to determine the profile of IgG subclasses specifically reactive to F6 in different categories of bancroftian filariasis cases to infer any relationship between the levels of a particular F6-specific IgG subclass and the infection or disease status. Methods: Serum samples of normal individuals from filariasis non-endemic regions of India like Jammu & Kashmir, Uttarakhand, and Chandigarh [(NEN-W; n=10), healthy subjects from USA (NEN-U; n=10) and three categories of bancroftian filariasis cases from endemic areas: endemic normals (EN; n=10) with no symptoms and no microfilariae, asymptomatic microfilaremics (ASM; n=10) and chronic symptomatic amicrofilaremics (CL; n=10) were assayed for F6-specific IgG1, IgG2, IgG3 and IgG4 by ELISA using SDS-PAGE-isolated F6 fraction of B. malayi adult worms. Results: Significantly high levels of F6-specific IgG1, IgG2 and IgG3 were found in CL (P<0.001) and EN (P<0.01-0.001) bancroftian filariasis cases compared to NEN-U. Significant levels of F6-specific IgG1 (P<0.01) and IgG2 (P<0.01) but not IgG3 were found in ASM cases compared to NEN-U. The most abundant was IgG2 which when compared to NEN-U, was significantly high in CL (P<0.001) and EN cases (P<0.001), followed by ASM (P<0.01). F6-specific IgG4 response in EN, ASM and CL subjects was not significantly different from the levels of NEN-U. Among the non-endemic normals, the NEN-W subjects showed significant reactivity with IgG2 (P<0.001) but not with IgG1, IgG3 and IgG4 as compared to NEN-U subjects. IgG subclass levels were different in different categories. Interpretation & conclusions: The high levels of F6 reactive IgG1, IgG2 and IgG3 in endemic normals and chronic symptomatic bancroftian patients, and IgG1 and IgG2 in asymptomatic microfilaraemics, suggest that F6 molecules of parasite are accessible in these subjects for IgG subclass-specific immune response and IgG2 may be related to pathogenesis. Studies using individual F6 molecules will be done to identify the molecule(s) involved in infection and protective immunity.

Assessment of chlorpyrifos toxicity on certain organs in rat, Rattus norvegicus.

Chlorpyrifos, an organophosphate insecticide of phosphorothioate group was orally administered to male rats at the doses of 3, 6 and 9 mg kg-1d-1 for 90 days. Animals exposed to high dose (9 mg kg-1d-1) showed signs of toxicity including piloerection, diarrhoea, nose and eye bleeding, reduced body weight and death of animals. Organ weight ratio of different vital organs did not show any change except increase in adrenal weight and decrease in the weight of testes in animals of high dose (9 mg kg-1d-1). A dose dependent inhibition of acetylcholinesterase (AChE) activity in RBC (22-60%) and brain (7-52%) was observed. Microscopic examination of different tissues of male rats showed minor histopathological changes in brain, liver, testis, epididymis and adrenal. The activity of testicular enzymes SDH, G-6-PDH and testicular content of sialic acid and cholesterol were found increased in animals of high dose (9 mg kg-1d-1). There was decrease in RBC counts and levels of hemoglobin (Hb) and hematocrit (HCT) with increase in WBC counts. While, total protein was decreased significantly at all the dose levels in testes and epididymis, glucose level showed a significant decrease at high dose. A dose dependent increase was observed in the level of serum triglycerides. There was no change in sperm motility and sperm morphology at any dose level except a decrease in sperm counts (114.1x 106 g-1 in high dose for group against 158.9 x 106 g-1 controls). It is suggested that chlorpyrifos at 9mg/kg/d dose for 90 days has caused toxicological changes along with mild testicular and spermatotoxic effects in male rats.

A study of the 2006 Chikungunya Epidemic Outbreak in Mauritius

Stem cells are basic cells of all multicellular organisms having the potency to differentiate into wide range of adult cells. Self renewal and totipotency are characteristic of stem cells. Though totipotency is shown by very early embryonic stem cells; the adult stem cells possess multipotency and differential plasticity which can be exploited for future generation of therapeutic options. Fortunately; the regulators of pleuripotency such as oct-4 et nanong protein are discovered and possibility of in vitro regulation of pleuripotency of stem cells is gaining strength. Genetic regulation of adult stem cells in the form of Bmi-1; Notch; sonic hedgehog et wnt gene is also being worked upon and future can be regulation of stem cell differentiation in vitro; in vivo or both. It is the knowledge of regulators of stem cells which has opened the therapeutic usage of stem cells in the form of neuron regeneration; treatment of bone defect; drug testing; gene therapy and cell based therapy in the form of muscle damage; spinal cord injury; cancer therapy etc. Cell based therapies might become commercial in coming years

In the course of systematic and ecological studies on algal flora of fresh water environment of three different agroclimatic zone of Uttar Pradesh revealed one hundred eighty two species represented by fifty-two genera inhabiting fresh water bodies having different physico-chemical properties. In both the regions members of order Conjugales were dominant and represented by ninety nine species belonging to fourteen genera. This is followed by Chlorococcales having fifty two species represented by nineteen genera and Chaetophorales with nine species of four genera only. In the central Uttar Pradesh a positive correlation was found between hydrogen ions concentration with temperature and species diversity, while in western Uttar Pradesh a highly positive correlation was found in electrical conductivity and total dissolved solids.

Inhibitory effect of the plant Boerhavia diffusa l. against the dermatophytic fungus Microsporum fulvum.

Antifungal activity (reduction in colony diameter) of various extracts (pt. ether, chloroform, ethyl acetate, ethyl alcohol and aqueous) of aerial and root parts of Boerhavia diffusa (Nictaginaceae) was screened against dermatophytic fungi Microsporum fulvum. Statistically significant increase has been recorded in the % inhibition of the target fungal species with increasing test concentrations (1000-5000 ppm) of chloroform, ethyl acetate and ethyl alcohol extracts of the root. The maximum % inhibition observed in various solvent extracts of root was about 26% (chloroform), 46% (ethyl alcohol) and 57% (ethyl acetate) at 5000 ppm concentration with time exposure of 10 days. The colony diameter of the target mycelial colony decreased with increasing supplementation of the phytoextract, showing the presence of significant amount of some antifungal phytochemical moiety.

Insecticidal activity of the plant Phyllanthus amarus against Tribolium castaneum.

The plant Phyllanthus amarus is used as folk medicine since the year 1800 and has been established for its important medicinal properties particularly for liver ailments. The present communication explores the insecticidal activity of ethanolic extract of aerial and root parts of this plant against stored grain pest Tribolium castaneum. LC 50 values of ethanolic aerial part were 895.77, 473.91, 279.89 and 260.85 microg/cm2, while 512.62, 376.96, 248.88 and 209.79 microg/cm2 for ethanolic root part at the exposure of 3, 5, 7, 9 and 11 days respectively. Ethanolic root extract possessed significant insecticidal activity against T. castaneum.

Antifungal activity of Boerhavia diffusa against some dermatophytic species of Microsporum.

Various extracts petroleum ether, chloroform, ethyl acetate and ethyl alcohol) of aerial and root parts of Boerhavia diffusa was sereened for Antitungal activity (Inhibition in sporulation) against dermatophytic fungi Microsporum gypseum, M. fulvum and M. canis by using broth dilution method. Extracts of aerial part not show any noticeable antifungal activity. Ethyl acetate extract of root part of the plant was found to be most effective of against target fungal species. The maximum inhibition of mycelial growth was observed for M. gypseum (78.83%) followed by M. fulvum (62.33%) and M. canis (42.30%) of ethyl acetate in the test concentration of 1000 microg/ml 24 hours of incubation. The sporulation of target fungal species decreases with increasing supplementation of phytoextract, confirms the presence of some antifungal phytochemical moiety in roots of the plant.

Plant availability of cadmium in presence of organic acids: an interactive aspect.

The present communication reports the effect of various carboxylic and amino acids on the uptake and translocation of root-absorbed Cd by maize (Zea mays). Statistically significant increases in Cd accumulation in various plant tissues with increasing supplementation of organic acids suggested the existence of Cd-organic acid interaction in soil-rhizosphere environment of the plant. The potentiality of phytochelators (organic acids) to form plant available organically bound Cd is discussed.

Uptake and translocation of selenium by maize (Zea mays) from its environmentaly important forms.

Pot culture studies were conducted to examine the effect of selenite (SeO3(2-)) and selenate (SeO4(2-)) on the uptake and translocation of root absorbed selenium in maize Zea mays plants grown in sand and soil culture. Increasing selenium supplementation (0.5-6.00 microg/ml), increased the selenium retention in roots, but there was little transfer of selenium from shoot to grains. The study indicates that selenite species (less mobile) also accumulates in maize plants when supplied in solution form. Selenium does not cause any adverse effect on the maize plants (dry matter yield vs concentration, no significant correlation, p>0.05).

Age prediction based on skeletal morphology.

Treatment plan for a child requires a complete diagnosis with monitoring of the skeleto-dental morphological changes during active period of growth. Growth modifications are done while the forces of growth are still at the peak of activity in a developing child. This study was undertaken on lateral cephalograms of 100 North Indian samples in the age group of 9-12 years consisting of 50 males and 50 females divided into normal occlusion and malocclusion groups, to predict and assess age by evaluating the skeleto-dental morphology in developing normal children having flush terminal plane molar relationship and children with developing class II pattern. It was concluded that based on measurements used in the study of dentofacial morphology, the age of a child could be statistically determined.

Assessment of toxicological effects of mancozeb in male rats after chronic exposure.

Mancozeb, an ethylenebisdithiocarbamate fungicide was administered orally to male rats at doses 0, 500, 1000 and 1500 mg/kg/day for 90, 180 and 360 days produced dose dependent signs of poisoning, loss in body weight gain and mortality. However the signs of toxicity and mortality were more pronounced initially at 0-90 days as compared to 90-360 days of treatment period. A significant increase in the relative weight of liver and slight decrease in the kidney weight were observed in animals exposed to mancozeb (1000 and 1500 mg/kg/day) for 180 and 360 days associated with pathomorphological changes in liver, brain and kidney. Mancozeb has produced significant enzymatic changes in the activities of aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and acetylcholinesterase (AChE) throughout the period of study in a dose dependent manner. The alterations in the activity of enzymes associated with pathomorphological changes suggest that the chronic exposure of mancozeb produced significant toxicological effects in rats.

Nutritional status of rural non-pregnant non-lactating women in reproductive age.

OBJECTIVE: To find out the degree of current undernutrition in rural reproductive age women. SETTING: 49 villages of two adjoining rural blocks of Varanasi. METHODS: 6130 non-pregnant and non-lactating rural women in the age group 18-45 year were studied for sociodemographic characteristics and anthropometry, i.e., weight, height and midarm circumferance. Their percentiles for age and for weight for height were calculated by using cubic spline method. RESULTS: The women in 10th centile weighed < 38 kg and those in > 90th centile weighed 47-48 kg; 74.2% had weight < 45 kg. The 50th centile height ranged between 148-150 cm; 13.5% were < 145 cm. For mid arm circumference 50th and 90th centile values were around 22 and 24 cm, respectively. Mid arm circumference and height had significant linear correlation with weight. CONCLUSION: Around 50% rural UP women in pre-pregnancy state are undernourished. With age these rural women did not change in weight or mid-arm circumference.
