RESUMO

Ischemic stroke is a major health issue, especially for the older population and it may have severe effects. Stroke diagnosis and treatment have advanced over the last 20 years, which has resulted in considerable reductions in death, long-term impairment, and the need for institutional care. Younger age groups have seen the majority of trials for acute, interventional, and preventive therapy. The purpose of this research was to identify distinct subgroups of older people who had suffered an ischemic stroke and examine the role that risk factors and previous illnesses played in their development. Ischemic stroke risk factors varied by age, gender and exhibited their own unique features. Smoking, cholesterol, and psychological/emotional stress were shown to have the greatest prevalence (p<0.06) among stroke patients aged 45-60. Smoking is associated with a significant (p<0.07) decline in health in elderly people. Our results imply that there are significant patterns of risk factors and preexisting illnesses among the various subgroups of older people who have had an ischemic stroke. Atherosclerotic (large-artery) and cardio embolic (small-artery) ischemic strokes were shown to be the most prevalent among the elderly. Strong associations were found between these subtypes and other risk factors, including higher cholesterol, diabetes, high blood pressure, and atrial fibrillation. This research emphasizes the need for individualized preventative methods and therapeutic therapy, as well as the need to recognize the variability of ischemic stroke in the elderly.

RESUMO

We aimed to assess the burden of NCDIs across socioeconomic groups, their economic impact, existing health service readiness and availability, current policy frameworks and national investment, and planned programmatic initiatives in Nepal through a comprehensive literature review. Secondary data from Global Burden of Disease estimates from GBD 2015 and National Living Standard Survey 2011 were used to estimate the burden of NCDI and present the relationship of NCDI burden with socioeconomic status. The Commission used these data to define priority NCDI conditions and recommend potential cost-effective, poverty-averting, and equity-promoting health system interventions. NCDIs disproportionately affect the health and well-being of poorer populations in Nepal and cause significant impoverishment. The Commission found a high diversity of NCDIs in Nepal, with approximately 60% of the morbidity and mortality caused by NCDIs without primary quantified behavioral or metabolic risk factors, and nearly half of all NCDI-related DALYs occurring in Nepalese younger than 40 years. The Commission prioritized an expanded set of twenty-five NCDI conditions and recommended introduction or scale-up of twenty-three evidence-based health sector interventions. Implementation of these interventions would avert an estimated 9680 premature deaths per annum by 2030 and would cost approximately $8.76 per capita. The Commission modelled potential financing mechanisms, including increased excise taxation on tobacco, alcohol, and sugar-sweetened beverages, which would provide significant revenue for NCDI-related expenditures. Overall, the Commission's conclusions are expected to be a valuable contribution to equitable NCDI planning in Nepal and similar resource-constrained settings globally.

RESUMO

The aim of the study was to analyze unrelated samples from the Rewa male population of Central India by targeting Y-short tandem repeats (STR) and then compare the results to previously published Y-STR haplotype data. Materials and Methods: A total of 181 unrelated male subjects from the Rewa population were genotyped for seventeen Y-STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385a/b, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, and Y-GATA-H4) by using an AmpFlSTR® Yfiler™ multiplex kit (Thermo Fisher Scientific, USA). The allele frequencies and forensic parameters were evaluated. Results: A total of 111 distinct Y-STR alleles with corresponding frequencies ranging from 0.006 to 0.829 were identified. The gene diversity values ranged from 0.3092 at DYS437 to 0.8188 at DYS385b. The studied population showed a high level of haplotype diversity (0.9985) and discrimination capacity (0.927). A haplotype analysis was also conducted. Among the 181 unrelated male samples, 165 haplotypes and 153 unique haplotypes were found. Additionally, Rst (genetic distance) values were calculated using the analysis of molecular variance (AMOVA) for the studied population and for other 18 populations described in the literature. The Rst provides a convenient parameter for estimating the level of genetic differentiation from the microsatellite data. Based on these Rst values and using the multidimensional scaling plot, a neighbor-joining tree was constructed. Conclusion: The high values of haplotype diversity and discrimination capacity indicate a great potential for distinguishing between male individuals in the studied population. The present population data are expected to find their use in forensic caseworks and population genetics.

RESUMO

Background Neurological patients who are ventilator-dependent occupy scarce beds in the hospitals for prolonged periods of time. Most, if not all, can be discharged on home mechanical ventilation (HMV). However, due to lack of insurance and state support, it remains prohibitively expensive for the vast majority of those who require it most. Materials and Methods The authors discuss three patients admitted in the Department of Neurosurgery between January and August 2019, who were discharged on HMV after remaining on ventilator support for prolonged period in the hospital. Each patient was discharged with two units (one as standby) of AgVa home ventilator (AgVa Healthcare; New Delhi, India), one Ambu-bag, one pulse oximeter, and one backup power supply unit capable of supplying power to ventilator for a minimum of 24 hours. All the equipment were given free-of-cost through donations by hospital staffs and other donors. All patients were followed up telephonically from their homes and the incidence of complications, ventilator malfunction, and additional cost of HMV on the families were ascertained. Observation and Results Of the three patients, two were male and one female. Age ranged from 12 to 17 years. The duration of in-hospital ventilator support prior to discharge on HMV varied from 1 to 5 years. There was no insurance cover available for any of the patients with all expenses being "out of pocket." The equipment cost Indian Rupees (INR) 115,700 (USD 1,615: two units of AgVa home ventilator costing INR 100,000 [USD 1,396], one Ambu-bag costing INR 1,100 [USD 15], one pulse oximeter costing INR 1,600 [USD 22], and one backup power supply unit costing INR 13,000 [USD 182]). Discharge on HMV was planned on specific request from patients' families and informed consent was taken from all. All patients had tracheostomies. Mode of HMV was pressure support ventilation in all. Telephonic follow-up ranged from 1 to 7 months. The cost of disposables was INR 100 per month (USD 0.7) for all the patients. No complications occurred in any patient. There was no incidence of ventilator-associated pneumonia (VAP) or ventilator malfunction. Conclusions Availability of cost-effective indigenous ventilator like AgVa home has made HMV possible, even for poor patients with neurological diseases, and has the potential to improve quality of life, decrease VAP rates, and free up scarce ventilator beds in hospitals. Longer-term follow-up in larger number of patients will improve the data on safety and feasibility in developing countries like India.

RESUMO

Pancreatic exocrine insufficiency (PEI) is a common long-term complication after pancreaticoduodenectomy (PD) and is observed in 23-80% of patients. As the postoperative mortality after PD has substantially decreased, it warrants more attention on the diagnosis and treatment of functional long-term consequences after PD. These include PEI and endocrine insufficiency that can result in significant nutritional impairment and often adversely impacts quality of life (QOL) of the patient. A PubMed search was performed for articles using key words "pancreatic exocrine insufficiency"; "pancreaticoduodenectomy"; "quality of life after pancreaticoduodenectomy"; "stool elastase"; "direct, indirect tests for pancreatic exocrine insufficiency"; "pancreatic enzyme replacement therapy." Relevant studies were shortlisted and analyzed. This review summarizes relevant studies addressing PEI following PD. We also discuss functional changes after PD, risk factors and predictive factors for postoperative PEI, clinical symptoms, direct and indirect tests for estimation of PEI, pancreatic enzyme replacement therapy (PERT), and QOL after pancreatic resection for malignancy. It was found that significant PEI occurs in most patients following PD. Fecal elastase 1 is an easy indirect test and should be performed routinely in both symptomatic and asymptomatic patients after PD. PERT should be considered in every patient after PD with the aim to improve the QOL and perhaps even their long time survival.

RESUMO

AIM: To evaluate the extraradicular peroxide release from sodium percarbonate compared to sodium perborate as an intracoronal bleaching agent. METHODOLOGY: Sixty mandibular single-rooted premolars with intact CEJ were selected. After root filling, gutta-percha was removed 4 mm apical to CEJ and 2 mm of GIC was condensed over the root filling. Intracoronal bleaching agents were placed into six groups of teeth (n = 10): sodium perborate with distilled water (SPW); sodium percarbonate with distilled water (SPCW); sodium perborate with 30% hydrogen peroxide (SPHP); sodium percarbonate with 30% hydrogen peroxide (SPCHP); 30% hydrogen peroxide as positive control (HP) and distilled water as negative control (CL). The teeth were then mounted in vials filled with distilled water, kept in an incubator and taken out at 1, 3 and 6 days for spectrophotometric analysis. Extraradicular peroxide release was quantified by the ferrothiocyanate method. Statistical analysis was undertaken with one-way anova and Scheffe post hoc tests. RESULTS: The greatest peroxide release occurred in the HP group, followed by the SPCHP and SPHP groups, and then by the SPCW and SPW groups. Intergroup comparison revealed that there was no significant difference in peroxide release among the groups SPCW and SPW on days 1, 3 and 6 (P > 0.05). Similarly, no significant difference was found between the SPCHP and SPHP treated groups on days 1, 3 and 6 (P > 0.05). CONCLUSION: Extraradicular peroxide release from sodium percarbonate was comparable to that of sodium perborate, as the differences were not significant.

RESUMO

Oral iron therapy is the most widely prescribed treatment for iron deficiency anemia. However, oral iron supplementation may also lead to various health problems. The recognition of these physiological variations is essential for the diagnosis of liver diseases during the course of pregnancy. Therefore, the objective of this study was to assess the variations in levels of routine liver function tests (LFTs) in pregnant women before and after iron and folic acid treatment. Iron and folic acid was supplemented to 500 normal pregnant anemic women (mild=200, moderate=200 and severe=100) and 100 age matched normal pregnant non-anemic as controls daily for 100 days. Blood index values and liver function parameters were precisely monitored. Hemoglobin (Hb), total protein (TP), iron (Fe), albumin and alkaline phosphatase (ALP) levels were found increased (P<0.001; P<0.01; P<0.05) after treatment in mild, moderate, severe and control, respectively. Lipid peroxidation (LPx), aspartate transaminase (AST) and alanine transaminase (ALT) were increased in pretreated mild, moderate and severe groups and further increased after all treated subjects. Moreover, gamma-glutamyl transpeptidase (GGT) was found to decrease in pre and posttreated subjects. Treatment with iron and folic acid although has remarkable efficacy for Hb and body iron stores although for the cost of increasing the associated compartment of total bilirubin, AST and ALT concomitant with decreased GGT levels. Data obtained from the present study provide new insights into the mandatory application of liver function tests likely to be monitored at regular and specific intervals during the course of pregnancy.

RESUMO

BACKGROUND: Inclusion of inhomogeneity corrections in intensity modulated small fields always makes conformal irradiation of lung tumor very complicated in accurate dose delivery. OBJECTIVE: In the present study, the performance of five algorithms via Monte Carlo, Pencil Beam, Convolution, Fast Superposition and Superposition were evaluated in lung cancer Intensity Modulated Radiotherapy planning. MATERIALS AND METHODS: Treatment plans for ten lung cancer patients previously planned on Monte Carlo algorithm were re-planned using same treatment planning indices (gantry angel, rank, power etc.) in other four algorithms. RESULTS: The values of radiotherapy planning parameters such as Mean dose, volume of 95% isodose line, Conformity Index, Homogeneity Index for target, Maximum dose, Mean dose; %Volume receiving 20Gy or more by contralateral lung; % volume receiving 30 Gy or more; % volume receiving 25 Gy or more, Mean dose received by heart; %volume receiving 35Gy or more; %volume receiving 50Gy or more, Mean dose to Easophagous; % Volume receiving 45Gy or more, Maximum dose received by Spinal cord and Total monitor unit, Volume of 50 % isodose lines were recorded for all ten patients. Performance of different algorithms was also evaluated statistically. CONCLUSION: MC and PB algorithms found better as for tumor coverage, dose distribution homogeneity in Planning Target Volume and minimal dose to organ at risks are concerned. Superposition algorithms found to be better than convolution and fast superposition. In the case of tumors located centrally, it is recommended to use Monte Carlo algorithms for the optimal use of radiotherapy.

RESUMO

BACKGROUND: Visual damage due to diabetic retinopathy is a major concern which can be reduced through appropriate coordination and cooperation between the diabetes management services and diabetic retinopathy services. The study assessed the existence, availability and accessibility of health care services for diabetes mellitus and diabetic retinopathy in Nepal. METHODS: The study was carried out from 1 April to 24 June 2015. The tool for assessment of diabetic retinopathy and diabetes management systems developed by the World Health Organization was used for the assessment of major stakeholders like endocrinologists, ophthalmologists, ophthalmic assistants, nurses involved in diabetes care, patients and human resources from Ministry of Health and Population and international non-governmental organizations dealing with eye care services in Nepal. RESULTS: Thirty-seven key stakeholders were selected for the study. Six out of fifteen ophthalmologists were unaware about the prioritization of diabetes as national health concern. The main function of diabetes association included patient education and awareness 18(48.6%), clinician education and awareness 16(43.2%). Thirteen professionals (35.1%) said that the patients were not found to be aware about diabetic patients' organizations. The information to community is provided occasionally and only through national-level media. All forms of diabetes care were funded out-of-pocket by the patients themselves. CONCLUSIONS: Coordination should be strengthened for an effective and holistic management of diabetes mellitus making diabetes care and diabetic retinopathy services more accessible. Diabetes mellitus and its complications are becoming a public health threat in Nepal.

RESUMO

BACKGROUND: Nepal is not an exception to alcohol use; urban poor are more prone than the general population. The question of social consequences of alcohol use among urban poor remains largely unanswered in Nepal. Study explored the alcohol linked social consequences among the urban poor of Kathmandu Valley. METHODS: Taking 422 urban poor from four squatter settlements of Kathmandu Valley, a cross-sectional study was carried out. A series of univariate and bivariate analysis were performed in R version 3.1.2. RESULTS: Four out of 10 current drinkers (42.86%, 95% CI: 31.4-54.3) encountered various social consequences. The number one consequence hitting 23.19% drinkers was money loss. Male drinkers were 4.43 times (95% CI: 1.810.8) more likely to face social consequences than their female counterparts. Being male frequent drinker increased the odds of social consequence 3.80 times (95% CI:1.3-11.0) than that of female frequent drinker. CONCLUSIONS: A behaviour change communication campaign needs initiation; male populace and frequent drinkers being the target.

RESUMO

OBJECTIVE: To explore the cost-effectiveness of artesunate against quinine based principally on the findings of a large multi-centre trial carried out in Southeast Asia. METHODS: Trial data were used to compare mortality of patients with severe malaria, treated with either artesunate or quinine. This was combined with retrospectively collected cost data to estimate the incremental cost per death averted with the use of artesunate instead of quinine. RESULTS: The incremental cost per death averted using artesunate was approximately 140 USD. Artesunate maintained this high level of cost-effectiveness also when allowing for the uncertainty surrounding the cost and effectiveness assessments. CONCLUSION: This analysis confirms the vast superiority of artesunate for treatment of severe malaria from an economic as well as a clinical perspective.

RESUMO

BACKGROUND: The Remote Medical Diagnostics kit is an indigenous and low-cost technology that can measure and transmit via the internet 6 clinical parameters viz. Blood pressure (BP), pulse, temperature, oxygen saturation, 12-lead Electrocardiogram (ECG) and heart/breath sounds. Prior to commercial use, it needs clinical validation. METHODS: Fifty three patients (including 1 acute myocardial infarction) were evaluated for the above parameters using accepted standard methods and the Remote Medical Diagnostics kit. RESULTS: The intraclass correlation coefficient (ICC) for systolic BP (SBP), diastolic BP (DBP), saturation pulse, manual pulse and temperature was 0.927, 0.904, 0.989, 0.99 and 0.912 indicating a high degree of agreement between the two methods. For oxygen saturation, the ICC was 0.763 indicating a moderately high agreement. For heart sounds, the kappa coefficient (kappa) for inter-rater reliability was 0.48 (observed agreement of 96.1%). For breath sounds, the 'kappa' value was 0.48 indicating moderate agreement. For the breath sounds, the 'kappa' value was 0.38, indicating fair agreement (the observed agreement of 94.2%). For the ECG, the observed agreement was 94.4% by visual assessment. CONCLUSION: At the bedside, the Remote Medical Diagnostics kit was clinically validated for the above 6 parameters.

RESUMO

In a study undertaken among rural and urban communities in a district of Orissa, India, the personal-protection measures used against mosquitoes, and the household costs of these measures, were investigated. Most people living in the study communities perceived mosquitoes as a problem, both as a biting nuisance and as vectors of human disease. Almost all (99%) of the urban households investigated and most (84%) of the rural each reported the use of at least one measure against mosquitoes. Most of the study households (92% of the urban and 64% of the rural) used a 'modern' chemical method (coils, vaporizing mats, liquid vaporizers or sprays), with mosquito coils used more frequently than any other personal-protection measure. Untreated bednets were also used by most of the households investigated (76% of the urban and 58% of the rural) and some households (about 10% of the urban and 8% of the rural) still used the more traditional method of burning dried dung or vegetation indoors, specifically to create smoke to drive away mosquitoes. Setting, house type, as indicated by the material used as roofing, and number of people in the household were each a significant predictor of the use of personal protection, with households in an urban setting, large households, and households occupying a concrete-roofed building relatively more likely to use some form of personal protection. Although 'modern', chemical-based methods were frequently employed, about one in every two interviewees (57% of the urban and 43% of the rural) considered the use of such methods to be harmful to their health. The mean monthly expenditures on personal-protection measures were 101 Indian rupees (U.S.$2.20)/urban household and 72 Indian rupees (U.S.$1.60)/rural household. Setting, family income, family size and number of sleeping rooms in the house each affected such expenditure significantly. As a proportion of household income, expenditure on controlling mosquitoes was surprisingly high.

RESUMO

Trace metals and organometals were estimated in different types of marine organisms (fish, bivalve, crab and prawn) collected from the Trans-Thane Creek area, Mumbai. Thane Creek area is considered as most polluted area due to industrial discharges. Potential risks associated with consumption of marine organisms collected from this particular area to human beings were assessed. Concentrations of ten trace elements (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb and Zn) in the edible part of marine organisms were analysed by atomic absorption spectrometer and differential pulse anodic stripping voltametric technique. Methyl mercury and tributyl tin were estimated using gas chromatograph-mass spectrometer in combination with solid phase micro extraction (SPME). An assessment of the risk on human beings due to consumption of marine organism was undertaken using toxic reference benchmark, namely the reference dose (RfD). The hazard index (HI), sum of hazard quotients calculated for all the pollutant showed that the risks from consumption of fish and marine organisms as a whole were generally low and are within safe limits.

RESUMO

Microsatellite instability (MSI) is an indicator of a defective DNA mismatch repair system (MMR) that results from somatic mutations. The present work has been planned to investigate MSI and its clinical significance in human urinary bladder and thyroid cancers in Indian patients. Tumor tissues of histologically confirmed cases of urinary bladder and thyroid cancers, respectively, were obtained. Clinical data on tumor stage and histopathological grades were recorded. Corresponding matched peripheral blood was taken as a control. Genomic DNA was isolated from the tumor tissues and blood using a standard phenol-chloroform extraction method. Polymerase chain reaction was done to amplify mononucleotide microsatellite markers, BAT-26, BAT-40, TGFbetaRII, IGFIIR, hMSH3, and Bax by using specific primer sequences. For analysis of allelic patterns, the PCR products were run on 8% denaturing Polyacrylamide gel and sizing was done using a pUC18 sequencing ladder. The instability with BAT-26 and BAT-40 was found to be 20% and 45% in urinary bladder and 33% and 19% in thyroid cancers, respectively. However, no instability was observed with the other four-mononucleotide markers in either of the cancers studied. Eighty-three percent of the unstable urinary bladder cancers were found to have a high grade in a superficial group, whereas only 27% MSI+ve were muscle invasive cancers. Forty percent of unstable thyroid lesions were found to be at high risk of developing metastasis. Association of BAT-26 and BAT-40 instabilities with high grade tumors as well as risk tumors may help in choosing a more definite therapy at the outset.

RESUMO

We present 'Mishra's rhinoscope', a novel, cost-effective technique of zero-degree rigid nasoendoscopy with a modified otoscope, the results of which are comparable with the fibreoptic sinoscope. This is particularly suited for the developing world where financial constraints restrict the diagnosis of an occult nasal pathology.
