Résumé

Background & objectives: Zinc is a crucial micronutrient in adolescence, required for promoting growth and sexual maturation. Adolescents of some tribes may be at high risk of zinc deficiency due to dietary inadequacy and poor bioavailability of zinc from plant-based diets. This study aimed to evaluate the risk of zinc deficiency by estimating prevalence of inadequate zinc intake, prevalence of low serum zinc and stunting among tribal adolescents. Methods: A cross-sectional community-based survey was conducted among adolescents (10-19 yr) in three purposively selected districts where Bhil, Korku and Gond tribes were in majority. Structured data collection instrument comprising information about sociodemographic characteristics and dietary recall data was used. Anthropometric assessment was conducted by standardized weighing scales and anthropometry tapes, and blood sample was collected from antecubital vein into trace element-free vacutainers. Serum zinc was estimated using an atomic absorption spectrophotometer. Results: A total of 2310 households were approached for participation in the study, of which 2224 households having 5151 adolescents participated. Out of these enlisted adolescents, 4673 responded to dietary recall (90.7% response rate). Anthropometry of 2437 participants was carried out, and serum zinc was analyzed in 844 adolescents. The overall prevalence of dietary zinc inadequacy was 42.6 per cent [95% confidence interval (CI) 41.2 to 44.1] with reference to the estimated average requirement suggested by International Zinc Nutrition Consultative Group (IZiNCG) and 64.8 per cent (95% CI 63.4 to 66.2) with Indian Council of Medical Research-recommended requirements. Stunting was observed in 29 per cent (95% CI 27.2 to 30.8) participants. According to IZiNCG cut-offs, low serum zinc was detected in 57.5 per cent (95% CI 54.1 to 60.8) of adolescents, whereas it was 34.4 per cent (95% CI: 31.2-37.5) according to the national level cut-off. Interpretation & conclusions: Risk of dietary zinc inadequacy and low serum zinc concentration amongst adolescents of the Gond, Bhil and Korku tribes is a public health concern.

Résumé

Objective@#Indocyanine green video angiography (ICG-VA) is a routine while performing vascular surgery to assess patency of perforators, completeness of clipping and/or to assess patency of anastomosis. Its usefulness in assessing cerebral blood flow and perfusion is not well studied. This study is aimed to assess the cerebral blood flow and perfusion after temporary clipping and to correlate with the risk of ischemia. @*Methods@#Prospective analysis of intra-operative ICG-VA performed during temporary arterial occlusion in 38 patients from January 2014 to December 2018 was conducted. Co-relation with post-operative MR diffusion weighted imaging (MR DWI) in terms of vascular territory of interest within 48 hours of surgery was performed. Clinical outcome was assessed using modified Rankin Scale (mRS) score 1-month post-surgery. @*Results@#43 aneurysms in 38 patients clipped using ICG-VA were included in this study. No side effect of ICG dye was seen in any patients. The number of times temporary clips applied had a direct relationship to the delay in appearance of ICG in the surgical field which became statistically significant after application of 3rd temporary clip. Nine (23.7%) patients developed ischemia following the procedure confirmed by post-operative MR DWI and all the ischemic cases had visible decrease in ICG fluorescence post-temporary clipping. @*Conclusions@#No previous study had tried to assess the intraoperative cerebral blood flow and perfusion during temporary clipping of parent vessels during aneurysm surgery. The use of ICG-VA can be extended to assess perfusion in desired territory by merely assessing the degree of opacification.

Résumé

Brucellosis is a Gram-negative, aerobic zoonotic infection acquired by Brucella species and transmitted from animals to humans through the ingestion of infected food products, direct contact with an infected animal, or inhalation of aerosols. Usually, the disease remains undiagnosed due to lack of awareness and inadequate reporting and is a challenging health problem in tropical countries. We report a case of 16-year-old male presenting to us with chronic inflammatory symmetric polyarthritis misdiagnosed as juvenile idiopathic arthritis but later found to be suffering from brucellosis on reevaluation. Through this case report, we would like to highlight the possibility and advantage of the high degree of suspicion for an infectious etiology responsible for arthritis in the background of autoimmunity and would also like to emphasize on the possibility of Brucella inducing a false-positive response for young patients presenting with arthritis.

Résumé

Background: Thyroid hormones play an important physiological role to maintain balance of metabolism of entire human body. Erythrocyte abnormalities are frequently associated with thyroid disorder. Subclinical hypothyroidism, often a hidden entity, is associated with iron-deficiency anemia along with other hematological disorders. Thyroid hormones have a crucial role in metabolism and proliferation of blood cells. Thyroid dysfunction has profound effects on blood cells such as anemia, alters RBC indices including MCV, MCHC as well as iron stores. Present study was carried out to investigate and explore subclinical hypothyroid patients, to know the effect of subclinical hypothyroidism on hematological parameters and body iron store.Methods: This retrospective study included 200 newly diagnosed, untreated subclinical hypothyroid, and 200 healthy euthyroid individuals. The hematological parameters and thyroid profile of the subjects were assessed by the mean, standard deviation (SD). Student抯 t-test was used to report our results, with p-value <0.05 considered as statistically significant.Results: In this study we have compared hemoglobin level, red cell indices, serum Ferritin among study group and euthyroid healthy group and found that mean hemoglobin, serum ferritin and RBC indices were significantly depleted in subclinical hypothyroid patient in comparison to euthyroid group. 37 of total 200 [18.22%] newly diagnosed subclinical hypothyroid patients was suffering from Iron deficiency anemia with significant number of patients having hemoglobin level less than 10 gm%.Conclusions: Iron deficiency anemia is quite common in Subclinical hypothyroidism and is often associated with depleted body iron store and complication of getting converted into primary hypothyroidism. As there is no significant clinical manifestation of SCH at earlier stages with anemia it is advisable to routinely investigate it for early detection allowing its early management.

Résumé

RESUMO Objetivo: Examinar as características clínicas, o padrão de desmame e o desfecho de pacientes que necessitaram de ventilação mecânica por tempo prolongado em uma unidade de terapia intensiva em um país com recursos financeiros limitados. Métodos: Estudo prospectivo observacional em centro único, realizado na Índia, no qual todos os pacientes adultos que necessitaram de ventilação mecânica prolongada foram acompanhados quanto a duração e padrão do desmame, e à sobrevivência, tanto por ocasião da alta da unidade de terapia intensiva quanto após 12 meses. A definição de ventilação mecânica prolongada adotada foi a do consenso da National Association for Medical Direction of Respiratory Care. Resultados: Durante o período de 1 ano, 49 pacientes com média de idade de 49,7 anos receberam ventilação mecânica prolongada; 63% deles eram do sexo masculino e 84% tinham uma enfermidade de natureza clínica. As medianas dos escores APACHE II e SOFA quando da admissão foram, respectivamente, 17 e 9. O tempo mediano de ventilação foi 37 dias. A razão mais comum para início da ventilação foi insuficiência respiratória secundária à sepse (67%). O desmame foi iniciado em 39 (79,5%) pacientes, com sucesso em 34 deles (87%). A duração mediana do desmame foi de 14 (9,5 - 19) dias, e o tempo mediano de permanência na unidade de terapia intensiva foi 39 (32 - 58,5) dias. A duração do suporte com vasopressores e a necessidade de hemodiálise foram preditores independentes significantes de insucesso no desmame. No acompanhamento após 12 meses, 65% dos pacientes sobreviveram. Conclusão: Mais de um quarto dos pacientes com ventilação invasiva na unidade de terapia intensiva necessitaram de ventilação mecânica prolongada. Os desmames foram bem-sucedido em dois terços dos pacientes, e a maioria deles sobreviveu até o acompanhamento após 12 meses.


ABSTRACT Objective: This study aimed to examine the clinical characteristics, weaning pattern, and outcome of patients requiring prolonged mechanical ventilation in acute intensive care unit settings in a resource-limited country. Methods: This was a prospective single-center observational study in India, where all adult patients requiring prolonged ventilation were followed for weaning duration and pattern and for survival at both intensive care unit discharge and at 12 months. The definition of prolonged mechanical ventilation used was that of the National Association for Medical Direction of Respiratory Care. Results: During the one-year period, 49 patients with a mean age of 49.7 years had prolonged ventilation; 63% were male, and 84% had a medical illness. The median APACHE II and SOFA scores on admission were 17 and 9, respectively. The median number of ventilation days was 37. The most common reason for starting ventilation was respiratory failure secondary to sepsis (67%). Weaning was initiated in 39 (79.5%) patients, with success in 34 (87%). The median weaning duration was 14 (9.5 - 19) days, and the median length of intensive care unit stay was 39 (32 - 58.5) days. Duration of vasopressor support and need for hemodialysis were significant independent predictors of unsuccessful ventilator liberation. At the 12-month follow-up, 65% had survived. Conclusion: In acute intensive care units, more than one-fourth of patients with invasive ventilation required prolonged ventilation. Successful weaning was achieved in two-thirds of patients, and most survived at the 12-month follow-up.

Résumé

Background & objectives: Methicillin resistant Staphylococcus aureus (MRSA) are the commonest cause of osteomyelitis. The aim of this study was to evaluate the role of an alternative therapy i.e. application of S. aureus specific bacteriophages in cases of osteomyelitis caused by MRSA in animal model. Methods: Twenty two rabbits were included in this study. The first two rabbits were used to test the safety of phage cocktail while the remaining 20 rabbits were divided into three groups; group A (n=4) to assess the establishment of osteomyelitis; group B (n=4) osteomyelitis developed but therapy started only after six weeks; and group C (n=12) osteomyelitis developed and therapy started after three weeks. Groups B and C rabbits were treated with four doses of cocktail of seven virulent bacteriophages at the interval of 48 h. Comparison between three groups was made on the basis of observation of clinical, radiological, microbiological, and histopathological examinations. Results: Experimental group rabbits recovered from the illness in the subsequent two weeks of the therapy. Appetite and activity of the rabbits improved, local oedema, erythema and induration subsided. There were minimal changes associated with osteomyelitis in X-ray and histopathology also showed no signs of infection with new bone formation. Control B group rabbits also recovered well from the infection. Interpretation & conclusions: The present study shows a potential of phage therapy to treat difficult infections caused by multidrug resistant bacteria.

Résumé

The present study was undertaken to investigate the antidiabetic potential of tap roots of Potentilla fulgens in streptozotocin induced diabetic rat models. The crude powder, ethanolic, ethanolic: aqueous and aqueous extracts of tap roots were administered to normoglycemic- and streptozotocin (STZ)-induced diabetic rats in a single dose study. The ethanolic extract showed significant improvement in oral glucose tolerance and antihyperglycemic effect on sucrose loaded normal rats and STZ-induced diabetic rats. Of the isolated aqueous, n-butanol, chloroform and n-hexane soluble fractions of the active ethanolic extract of the roots, the aqueous fraction (100 mg/kg body weight) showed significant blood glucose lowering effect on STZ-induced diabetic rats. In a multiple dose study, aqueous fraction of ethanolic extract of P. fulgens roots significantly improved the body weight, percent glycated hemoglobin (%HbA1c), fasting blood glucose, oral glucose tolerance (OGTT), serum insulin, lipid profile, liver and kidney parameters in STZ-induced diabetic rats. The aqueous fraction also showed marked improvement in OGTT and serum insulin level in neonatal STZ-induced diabetic rats for 30 consecutive days. The aqueous fraction of the roots also inhibited the activity of alpha (α)-glucosidase enzyme in a dose dependent manner. In conclusion, the finding suggested that an aqueous fraction of tap roots of P. fulgens possessed potential antidiabetic activity.

Background: Kasni (Cichorium intybus L.) reported to play an important role in the effective management of serum liver enzymes SGPT & SGOT in various animal models and this study is extension to newly diagnosed patients of type 2 diabetes mellitus. Methods: Newly diagnosed 90 patients of Type2 DM, age 35-65years, of either sex were divided into 3 groups. In group I only Metformin sustained release once a day and in group II/III 6 grams crude seed powder or 50 ml decoction of crude seed powder was given twice a day for 90 days in combination with Metformin sustained release orally once in a day. Serum liver enzyme levels of SGPT & SGOT were measured at zero, 30th, 60th and 90th day. Results: All the three groups showed a significant reduction in SGPT & SGOT across the four time periods. Post hoc Tukey HSD test shown that there was a significant difference between group I & II (p=0.011) and group I & III (p=0.000) for SGPT and group I & II (p=0.012) and group I & III (p=0.000) for SGOT. Conclusions: The add on therapy with Kasni seed preparations is more effective for the management of altered SGPT and SGOT levels in Type2 diabetes mellitus patients than only oral hypoglycaemic agent in decreasing SGPT & SGOT of selected patients. Among Kasni seed preparation treated groups, decoction was found more effective than crude seed powder.

Résumé

Background: Data comparing tapentadol with an antidepressant is limited. A comparison of tapentadol with mirtazapine at different dose has not been performed, the other antidepressant in the same therapeutic class with a significant market share, has been undertaken. In the absence of relevant data to assess the place that tapentadol should occupy in the therapeutic arsenal, indirect comparisons are the most rigorous way to go. We conducted a study evaluate antidepressant and analgesic activity of tapentadol with mirtazapine at different doses in Swiss albino mice. Methods: Tapentadol was administered at 10, 20 and 40 mg/kg (i.p) once daily for 14 days to swiss albino mice of either sex. The immobility period for antidepressant activity of mice were recorded in forced swim test and reaction time for analgesic activity of mice were recorded in tail flick test of the control and drug treated group. The antidepressant and analgesic activity of tapentadol (10, 20, 40 mg/kg i.p) was compared with that of mirtazapine (3, 5, 7 mg/kg i.p), administered for 14 days. Results: Tapentadol produced better antidepressant at (20, 40 mg/kg), but less at 10 mg/kg and significant analgesic activity at all the three doses, as indicated by reduction in immobility times and increase in reaction time as compared to control. Mirtazapine produced no antinociceptive activity at 3 mg/kg, but significant at 5, 7 mg/kg and showed better antidepressant activity at all the three doses in mice. The result of this study indicates the better analgesic activity of tapentadol at all the doses and least antidepressant activity at 10 mg/kg, as compared to mirtazapine which has shown better antidepressant activity at all the three doses but no analgesic activity at 3 mg/kg. Conclusion: It can be concluded that tapentadol is a better drug in case of depression associated with pain compared to mirtazapine in mice.

Résumé

Female adnexal tumor of probable Wolffi an origin (FATWO) is a rare neoplasm arising from the remnants of the mesonephric duct. We report here a case of FATWO in a 70-year-old woman arising from the broad ligament and confi rmed on immunohistochemistry. Most of these tumors behave in a benign fashion but certain histological features like hypercellularity, cellular pleomorphism and nuclear atypia as seen in the index case may increase the rate of recurrence and metastasis. Therefore, close follow-up is recommended for FATWO.

Résumé

An adequate food intake, in terms of quantity and quality, is a key to healthy life. Malnutrition is the most serious consequence of food insecurity and has a multitude of health and economic implications. India has the world’s largest population living in slums, and these have largely been underserved areas. The State of Food Insecurity in the World (2012) estimates that India is home to more than 217 million undernourished people. Various studies have been conducted to assess food insecurity at the global level; however, the literature is limited as far as India is concerned. The present study was conducted with the objective of documenting the prevalence of food insecurity at the household level and the factors determining its existence in an urban slum population of northern India. This cross-sectional study was conducted in an urban resettlement colony of South Delhi, India. A pre-designed, pre-tested, semi-structured questionnaire was used for collecting socioeconomic details and information regarding dietary practices. Food insecurity was assessed using Household Food Insecurity Access Scale (HFIAS). Logistic regression analysis was performed to determine the factors associated with food insecurity. A total of 250 women were interviewed through house-to-house survey. Majority of the households were having a nuclear family (61.6%), with mean familysize being 5.5 (SD±2.5) and the mean monthly household income being INR 9,784 (SD±631). Nearly half (53.3%) of the mean monthly household income was spent on food. The study found that a total of 77.2% households were food-insecure, with 49.2% households being mildly food-insecure, 18.8% of the households being moderately food-insecure, and 9.2% of the households being severely food-insecure. Higher education of the women handling food (OR 0.37, 95% CI 0.15-0.92; p≤0.03) and number of earning members in the household (OR 0.68, 95% CI 0.48-0.98; p≤0.04) were associated with lesser chance/odds of being food-insecure. The study demonstrated a high prevalence of food insecurity in the marginalized section of the urban society. The Government of India needs to adopt urgent measures to combat this problem.

Résumé

Hippophae salicifolia, Elaeagnus pyriformis, Myrica esculenta and M. nagi are actinorhizal plants growing in the sacred forests of Northeast India with multipurpose uses. The present investigation was undertaken to determine the phenol, flavonoid and flavonol contents of the fresh fruit juice of these plant species including the antioxidant potential by means of DPPH, H2O2 and NO scavenging activity and FRP. The total phenolic, flavonoid and flavonol contents of fruit juice ranged from 321.68±0.06 to 76.67±0.01 mg/g GAE, 272.92±0.07 to 20.12±0.02 mg/g QE and 258.92±0.08 to 18.72±0.02 mg/g QE, respectively. At 2.0 mg/mL concentration, DPPH scavenging activity was found to be the highest in M. esculenta (89.62%) and the lowest in E. pyriformis (17.58%). The reducing power activity was found significantly higher in H. salicifolia juice, which increased with increase in concentration. The H2O2 scavenging activity of H. salicifolia juice was found to be as high as 98.78%, while Elaeagnus juice was found to be less effective with just 48.90%. Juice of H. salicifolia showed the greatest NO scavenging effect of 75.24% as compared to juice of E. pyriformis, where only 37.54% scavenging was observed at the same concentration. Taking into account all the experimental data, it can be said that the fruits of H. salicifolia and both M. nagi and M. esculenta have good antioxidant activity compared to fruits of E. pyriformis.

Résumé

Trees of Myrica sp. grow abundantly in the forests of Meghalaya, India. These trees are actinorhizal and harbour nitrogen-fixing Frankia in their root nodules and contribute positively towards the enhancement of nitrogen status of forest areas. They can be used in rejuvenation of mine spoils and nitrogen-depleted fallow lands generated due to slash and burn agriculture practiced in the area. We have studied the association of amplicon restriction patterns (ARPs) of Myrica ribosomal RNA gene and internal transcribed spacer (ITS) region and nitrogenase activity of its root nodules. We found that ARPs thus obtained could be used as markers for early screening of seedlings that could support strains of Frankia that fix atmospheric nitrogen more efficiently.

Résumé

The crude powder, ethanolic extract and aqueous, chloroform, hexane and n-butanol soluble fractions of ethanolic extract of heart wood of P. marsupium showed marked improvement on oral glucose tolerance post sucrose load in normal rats. All these fractions except aqueous fraction showed improvement on oral glucose tolerance post sucrose load on streptozotocin (STZ)-induced diabetic rats. The crude powder, ethanolic extract and hexane and n-butanol fractions showed marked decline in blood glucose level on STZ-induced diabetic rats. The ethanolic extract (100 mg/kg body weight) when given to STZ-induced diabetic rats for 10 consecutive days declined blood glucose, improved OGTT and increased their serum insulin levels. The ethanolic extract also showed marked improvement on oral glucose tolerance on high fat-low dosed STZ-induced diabetic rats and neonatally STZ treated rats. The ethanolic extract of P. marsupium also showed marked antidyslipidemic effects on high fat diet fed Syrian golden hamsters. Altered renal and hepatic function markers and serum insulin levels of high fat diet fed-low dosed STZ-treated diabetic rats were also found towards normalization when these animals were treated with ethanolic extract of P. marsupium for 28 consecutive days. The four out of five phenolic C-glycosides isolated from n-butanol fraction of ethanolic extract of P. marsupium enhanced glucose uptake by skeletal muscle cells (C2C12) in a dose dependent manner. It may primarily be concluded that phenolic-C-glycosides present in P. marsupium heart wood are the phytoconstituents responsible for the antihyperglycemic activity and validate the claim of antidiabetic activity of heart wood of P. marsupium.
