RESUMO

BACKGROUND: Women's education and empowerment are important predictors of contraceptive use across countries. However, two of the Indian states, namely, Punjab and Manipur, showed large variations in contraceptive use, despite the similar level of women's educational attainment and empowerment. Therefore, this paper attempts to understand variation in contraceptive use between these states, despite having similar level of educational attainment and empowerment among the married women. METHODS: This study primarily used cross-sectional data of the National Family Health Survey (NFHS) 2015-16 and to some extent the District Level Household Survey (DLHS) 2012-13 data. The analytical sample includes 13,730 currently married women in Punjab and 8,872 in Manipur. Modern contraceptive prevalence rate (mCPR) is the key outcome variable of this study. Bivariate, multivariate, and multilevel regression analysis are applied to understand the differences in mCPR between these states and its determinants. RESULTS: Mean years of schooling was about 8 years among women of both the states, and about 34% of the women in Punjab and 27% of the women in Manipur have high level of autonomy. Despite this, use of modern method was 66% in Punjab and only 13% in Manipur. Coverage of family planning program indicators were significantly lower in Manipur than Punjab - frontline workers' (FLWs) outreach for family planning was only 18% in Manipur compared to 52% in Punjab. Similarly, only 11% of the public health facilities in Manipur compared to 50% of the health facilities in Punjab were ready to provide at least one clinical method of family planning. CONCLUSION: Despite the similar level of individual level characteristics across the two states, poor coverage of family planning programs - low outreach of FLWs, low level of facility readiness, as well as sociocultural norms discouraging contraceptive use - might be responsible for lower contraceptive use in Manipur than Punjab. This implies for strengthening the health system for family planning in Manipur to meet the contraception needs of women by addressing sociocultural barriers in the state.

RESUMO

Chilika Lake is the largest coastal lagoon in Asia and the second largest in the world covering an area of 1100 km2 and spread over three districts of Odisha state of India. It is the first Indian wetland designated as a wetland of international importance under the Ramsar Convention in 1981. The lake ecosystem sustains large and diversified resources of plants and animals including fisheries. Pollution of the ecosystem caused by residues of pesticides originating from different sources was assessed through multiple sampling from 2012 to 2016 from three potential sites of contamination, viz., Palur Bridge, Daya River Estuary, and Makara River. Incidence of organochlorinated (OC) pesticide residues was noticed in about 25% water samples. HCH (α, γ&δ), DDD (op|), DDE (op|&pp.|) and heptachlor were the OCs detected in concentration varying from 0.025 to 23.4 µg/l. None of the eight targeted synthetic pyrethroid (SP) pesticides was found in water, but among the organophosphates (OP), chlorpyrifos (0.019-2.73 µg/l), and dichlorvos (0.647 µg/l) were recorded. In sediment samples, residues of OC or OP pesticides were not present, but one SP pesticide was recorded. Fish samples were contaminated to the extent of 55%, mostly with residues of OCs and OPs and less with SPs. However, their concentrations were below the permissible limit, so there was no direct threat of health hazards to humans.

RESUMO

Optogenetic stimulation of genetically targeted cells is proving to be a powerful tool in the study of cellular systems, both in vitro and in vivo. However, most opsins are activated in the visible spectrum, where significant absorption and scattering of stimulating light occurs, leading to low penetration depth and less precise stimulation. Since we first (to the best of our knowledge) demonstrated two-photon optogenetic stimulation (TPOS), it has gained considerable interest in the probing of cellular circuitry by precise spatial modulation. However, all existing methods use microscope objectives and complex scanning beam geometries. Here, we report a nonscanning method based on multimode fiber to accomplish fiber-optic TPOS of cells.

RESUMO

The controlled navigation of the axonal growth cone of a neuron toward the dendrite of its synaptic partner neuron is the fundamental process in forming neuronal circuitry. While a number of technologies have been pursued for axonal guidance over the past decades, they are either invasive or not controllable with high spatial and temporal resolution and are often limited by low guidance efficacy. Here, we report a neuronal beacon based on light for highly efficient and controlled guidance of cortical primary neurons.

RESUMO

AIMS: This multicentric retrospective study reports long-term clinical outcomes of non-metastatic grade group 5 prostate cancers treated with external beam radiotherapy (EBRT) alone with long-term androgen deprivation therapy (ADT). MATERIALS AND METHODS: Patients treated across 19 institutions were studied. The key endpoints that were evaluated were 5-year biochemical recurrence-free survival (bRFS), metastases-free survival (MFS), overall survival, together with EBRT-related acute and late toxicities. The impact of various prognostic factors on the studied endpoints was analysed using univariate and multivariate analyses. RESULTS: Among the 462 patients, 88% (405) had Gleason 9 disease and 31% (142) had primary Gleason pattern 5. A prostate-specific membrane antigen positron emission tomography-computed tomography scan was used for staging in 33% (153), 80% (371) were staged as T3/T4 and 30% (142) with pelvic nodal disease. The median ADT duration was 24 months; 66% received hypofractionated EBRT and 71.4% (330) received pelvic nodal irradiation. With a median follow-up of 56 months, the 5-year bRFS, MFS and overall survival were 73.1%, 77.4% and 90.5%, respectively. Primary Gleason pattern 5 was associated with worse bRFS, MFS and overall survival with hazard ratios of 0.51 (95% confidence interval 0.35 to 0.73, P < 0.001), 0.64 (95% confidence interval 0.43 to 0.96, P = 0.031) and 0.52 (95% confidence interval 0.28 to 0.97, P = 0.040), respectively, whereas pelvic nodal disease was associated with worse bRFS (hazard ratio 0.67, 95% confidence interval 0.46 to 0.98, P = 0.039) and MFS (hazard ratio 0.56, 95% confidence interval 0.37 to 0.85, P = 0.006). The acute and late radiation-related toxicities were low overall and pelvic nodal irradiation was associated with higher toxicities. CONCLUSION: Contemporary EBRT and long-term ADT led to excellent 5-year clinical outcomes and low rates of toxicity in this cohort of non-metastatic grade group 5 prostate cancers. Primary Gleason pattern 5 and pelvic node disease portends inferior clinical outcomes.

RESUMO

Platinum (Pt) nanoparticles embedded in a carbon matrix were synthesized for the first time in benzene by an electric plasma discharge generated in the cavitation field of benzene due to an ultrasonic horn. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to study the particle size, structure and morphology of the synthesized nanoparticles. The Pt nanoparticles have FCC bulk Pt crystal structure. On the average Pt nanoparticle diameter ranged from 8 nm to 40 nm when synthesized at 4.1 kV and from 5 nm to 25 nm when synthesized at 3.4 kV. X-ray photoelectron Spectroscopy (XPS) and Energy dispersive X-ray Spectroscopy (EDX) were used to study the chemical composition of the synthesized nanoparticles. A cost effective new method for carbon supported Pt nanoparticles will be of potential interest in fuel cell and catalysis applications.

RESUMO

BACKGROUND: Ragi (Eleusine Coracana) is a major food crop for the tribal population of India. OBJECTIVE: This study emphasizes the need to consider ergonomics aspects in the design and development of a pedal operated ragi thresher (PORT) for tribal people, and assesses the drudgery as well as ergonomic evaluation of a developed thresher against the conventional practice. METHODS: Thirty subjects (male = 15 and female = 15) from the tribal region were evaluated ergonomically. The physiological responses of the subjects were studied and their performance was compared. RESULTS: The results revealed that the working heart rate, oxygen consumption rate and overall discomfort rating were significantly higher in case of traditional threshing as compared to those in case of PORT. Postural analysis identified the traditional method as the most fatigue one as the person has to lift the hand above shoulder level repeatedly and has to sit in a squatting posture for long period. CONCLUSION: The drudgery and occupational hazards to public health involved in the traditional method of threshing was reduced by using the PORT. Furthermore, the traditional method involved continuous stressed actions across the entire body, whereas the PORT involved only the lower limbs.

RESUMO

This paper examines the trends in utilization of five indicators of reproductive and child health services, namely, childhood immunization, medical assistance at delivery, antenatal care, contraceptive use and unmet need for contraception, by wealth index of the household in India and two disparate states, Uttar Pradesh and Maharashtra. The data from three rounds of the National Family and Health Survey conducted during 1992-2005 are analysed. The wealth index is computed using principal component derived weights from a set of consumer durables, land size, housing quality and water and sanitation facilities of the household, and classified into quintiles for all three rounds. Bivariate analyses, rich-poor ratio and concentration index are used to understand the trends in utilization of, and inequality in, reproductive and child health services. The results indicate huge disparities in utilization of these services, largely to the disadvantage of the poor. Utilization of basic childhood immunization among the poorest and the poor stagnated in India, as well as in both states, during 1998-2005 compared with 1992-1998. The use of maternal care services such as medical assistance at delivery and antenatal care remained at a low level among the poor over this period. However, contraceptive use increased relatively faster among the poor, even with higher unmet need. Of all these services, the inequality in medical assistance at delivery is consistently large, while that of contraceptive use is small. The state-level differences in service coverage by wealth quintiles over time are large.

RESUMO

This questioner survey aimed about awareness of the Cone Beam Computed Tomography (CBCT) machine and its various clinical applications in ENT, among the ENT surgeons in the state of Odisha. 150 questioner forms on CBCT were distributed to the all the participating ENT surgeons at a state level ENT conference, out of which the response rate was 110. The participants were asked to answer 30 multiple choice questions, which were divided into 3 parts; general information on CBCT, general approach to CBCT and practice related to CBCT. The statistical analysis of the data collected was carried out by a Chi square test to compare the means at a significance level of P < 0.05. The response rate for this study was 73%. The mean age of the participant ENT surgeons was 47.9 (±19.2). Of the study population, 71.2% (89) did not ever advice CBCT in their practice. Only 33.9% (38) of the population believed that CBCT is more beneficial in the field of ENT. Only 25% (28) knew that CBCT requires lower radiation dose than conventional CT. 28.1% (31) of population believed that the spatial orientation is better in CBCT than CT. 62.5% (69) of the population did not knew that CBCT can be used in imaging sinusitis of dental origins. 75% (83) of the population did not knew that CBCT can be used in diagnosis of obstructive sleep apnoea and visualizing airway space. Only 18.8% (21) of the study population agreed that the CBCT has the potential to replace conventional CT in ENT imaging in future. In the conclusion, this study clearly showed that the number of ENT surgeons advising CBCT imaging in their practice is very less. The knowledge about various advantages and clinical applications of CBCT had been very limited. However, through continuing medical education and conducting various seminars and workshops on CBCT, imparting chapters on CBCT, in the undergraduate and post graduate curriculum will definitely help increase the awareness on CBCT among ENT fraternity.

RESUMO

CONTEXT: Although there is a growing body of research examining the issue of nonconsensual sex among adolescents, few studies have looked at coerced sex within marriage in settings where early marriage is common, or at sex that may not be perceived as forced, but that is unwanted. METHODS: A cross-sectional study, using both survey research and in-depth interviews, was conducted among 1,664 married young women in Gujarat and West Bengal, India. Descriptive data and multinomial logistic regression were used to identify the prevalence and risk factors for occasional and frequent unwanted sex. Qualitative data were analyzed to examine the context in which unwanted sex takes place. RESULTS: Twelve percent of married young women experienced unwanted sex frequently; 32% experienced it occasionally. The risk of experiencing unwanted sex was lower among women who knew their husband fairly well at the time of marriage, regularly received support from their husband in conflicts with other family members or lived in economically better-off households. Frequent unwanted sex was associated with not yet having had a child or having become pregnant, with lower education and with agreeing with norms that justify wife beating. CONCLUSION: For married young women, sex is not always consensual or wanted. Further research is required to determine the effects of unwanted sex on sexual and reproductive health outcomes and to help programs develop the best strategies for dealing with coerced sex within marriage.

RESUMO

Individual carbon nanotubes being substantially smaller than the wavelength of light, are not much responsive to optical manipulation. Here we demonstrate how decorating single-walled carbon nanotubes with palladium particles makes optical trapping and manipulation easier. Palladium decorated nanotubes (Pd/SWNTs) have higher effective dielectric constant and are trapped at much lower laser power level with greater ease. In addition, we report the transportation of Pd/SWNTs using an asymmetric line trap. Using this method carbon nanotubes can be transported in any desired direction with high transportation speed.

RESUMO

BACKGROUND: Management of vascular injuries poses a challenging problem under warlike conditions. Several authorities recommend limb revascularisation only within first 6-8 hours, as the outcome after delayed revascularisation is poor. METHODS: A retrospective analysis of 61 consecutive patients with vascular injury in a forward hospital over a 25- month period was carried out. RESULTS: Vascular injuries constituted 3.1% of all injuries. The mean injury to treatment delay (lag time) was 11 hours, and 10 patients received treatment after 12 hours. The overall amputation rate was 15%, but only 6.5% for those revascularised within 12 hours and 44% for those undergoing surgery after 12 hours (Chi-square 4.59, p < 0.05). Presence of associated fractures was associated with an adverse outcome (Chi-square 4.24, p < 0.05), as was ligation in comparison to revascularisation (Chi-square 7.86, p < 0.005). Popliteal injuries were associated with a high amputation rate. CONCLUSIONS: Failure to revascularise (ligation of artery), presence of associated fracture, and restoration of circulation beyond 12 hours are associated with a high amputation rate.

RESUMO

DNA damage induced in NC37 lymphoblasts by optical tweezers with a continuous-wave Ti:sapphire laser and a continuous-wave Nd:YAG laser (60-240 mW; 10-50 TJ/m2; 30-120 s irradiation) was studied with the comet assay, a single-cell technique used to detect DNA fragmentation in genomes. Over the wavelength range of 750-1064 nm, the amount of damage in DNA peaks at around 760 nm, with the fraction of DNA damage within the range of 750-780 nm being a factor of two larger than the fraction of DNA damage within the range of 800-1064 nm. The variation in DNA damage was not significant over the range of 800-1064 nm. When the logarithm of damage thresholds measured in the present work, as well as values reported previously in the UV range, was plotted as a function of wavelength, a dramatic wavelength dependence became apparent. The damage threshold values can be fitted on two straight lines, one for continuous-wave sources and the other for pulsed sources, irrespective of the type of source used (e.g. classical lamp or laser). The damage threshold around 760 nm falls on the line extrapolated from values for UV-radiation-induced damage, while the data for 800-1064 nm fall on a line that has a different slope. The change in the slope between 320 and 340 nm observed earlier is consistent with a well-known change in DNA-damaging mechanisms. The change observed around 780 nm is therefore suggestive of a further change in the mechanism(s). The data from this work together with our previous measurements provide, to the best of our knowledge, the most comprehensive view available of the DNA damage produced by microfocused light.

RESUMO

During the months of May-June 2000, 194 patients with watery diarrhoea were admitted to the Infectious Diseases Ward of the M.K.C.G. Medical College, Berhampur. Ninety four rectal swabs were collected and processed according to the standard procedures. Vibrio cholerae strains were isolated from 20 samples. Of these 20 isolates, two were found to be V. cholerae O1 EITor Ogawa strain and 18 were confirmed to be V. cholerae serotype O139. All V. cholerae O139 isolates were of a single phage type (phage type 1) and the two O1 strains were of phage type 3 and phage type 27 respectively. All 20 V. cholerae isolates were positive for CAMP test, and showed uniform resistance to furazolidone and sensitivity to co-trimoxazole, amoxycillin, norfloxacin, tetracycline and gentamycin. V. cholerae O139 serotype has not been reported earlier in south Orissa. This is probably the first report of its isolation from this area.

RESUMO

Mesenteric and retroperitoneal cysts develop from ectopic lymphatic tissue. Most of them present as symptomless abdominal swellings or are found coincidentally during abdominal operations. One third of patients may present with acute abdominal pain, and few may present with chronic abdominal pain. However, mesenteric cyst presenting as inguinal hernia is extremely rare. Only four cases have been reported in the English-language literature. The present case is the fifth, and only the second from this subcontinent. The treatment of choice is complete surgical excision.

RESUMO

PURPOSE: The results of epispadias repair using Mitchell's technique in nine patients is analyzed and the advantages of the procedure discussed. METHODS: Nine boys aged between 6 weeks and 6 years underwent epispadias repair between November 1996 and March 1998 (Penopubic epispadias, inferior vesical fissure, and midpenile epispadias, one patient each; exstrophy epispadias complex, six patients). Eight patients had first attempt at repair of epispadias. Two patients had closure of exstrophy and epispadias at one stage. RESULTS: At a mean follow-up of 10 months, all children had a conical glans, eight patients had ventral orthotopic meatus, and one had coronal hypospadiac meatus. Minor penopubic fistula developed in one patient. Six patients had downward angled penis, and three had horizontal penis in a flaccid state. All children were observed to have good erections during sleep. CONCLUSIONS: Mitchell's technique of epispadias repair allows an anatomic reconstruction of the penis with superior cosmetic and functional results. Long-term follow-up studies are necessary to evaluate the genital functions.

RESUMO

Two mouse monoclonal antibodies (MAbs), viz. 2B7 and 2 D10 raised against haemagglutinin-neuraminidase glycoprotein of Newcastle disease virus (NDV) were used to identify several other field isolates and vaccine strains of NDV. These MAbs reacted specifically with all the NDV strains/isolates in Dot-ELISA whereas, only MAb 2D10 reacted with all the NDV strains/isolates in agar gel precipitation test. These two tests employing the MAbs were standardised for rapid diagnosis and identification of NDV.

RESUMO

A mycological study was undertaken in 250 cases of superficial mycotic infections, which included 210 cases of dermatophytosis, 18 cases of cutaneous candidiasis and 22 cases of tinea versicolor. The scrapings from all the cases were subjected to direct microscopic examination in 10% KOH solution and culture was done in case of candidiasis and dermatophytosis. Out of 250 cases direct microscopy was positive (KOH +ve) in 88 cases of dermatophytosis, 11 cases of candidiasis and all cases of tinea versicolor. Culture for dermatophytes and candida species in SDA medium were positive in 76 and 9 cases respectively. The diagnostic sensitivity, specificity, positive predictive value, negative predictive value and the overall efficiency of the direct microscopy in the diagnosis of superficial mycotic infections were calculated to be 89.41%, 83.90%, 76.76%, 93.02% and 85.96% respectively.
