Polymorphisms of Glutathione S-transferases Omega-1 among ethnic populations in China

<p>Abstract</p> <p>Background</p> <p>Glutathione S-transferases (GSTs) is a genetic factor for many diseases and exhibits great diversities among various populations. We assessed association of the genotypes of Glutathione S-transferases Omega-1 (GSTO1) A140D with ethnicity in China.</p> <p>Results</p> <p>Peripheral blood samples were obtained from 1314 individuals from 14 ethnic groups. Polymorphisms of GSTO1 A140D were measured using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Logistic regression was employed to adjustment for regional factor. The frequency of GSTO1 140A allele was 15.49% in the total 14 ethnic populations. Compared to Han ethnic group, two ethnic populations were more likely to have AA or CA genotype [odds ratio (OR): 1.77, 95% confidence interval (95% CI): 1.05–2.98 for Uygur and OR: 1.78, 95% CI: 1.18–2.69 for Hui]. However, there were no statistically significant differences across 14 ethnic groups when region factor was adjusted. In Han ethnicity, region was significantly associated with AA or CA genotype. Han individuals who resided in North-west of China were more likely to have these genotypes than those in South of China (OR: 1.63, 95% CI: 1.21–2.20).</p> <p>Conclusion</p> <p>The prevalence of the GSTO1 140A varied significantly among different regional populations in China, which showed that geography played a more important role in the population differentiation for this allele than the ethnicity/race.</p

Two-dimensional electrophoretic comparison of metastatic and non-metastatic human breast tumors using in vitro cultured epithelial cells derived from the cancer tissues

<p>Abstract</p> <p>Background</p> <p>Breast carcinomas represent a heterogeneous group of tumors diverse in behavior, outcome, and response to therapy. Identification of proteins resembling the tumor biology can improve the diagnosis, prediction, treatment selection, and targeting of therapy. Since the beginning of the post-genomic era, the focus of molecular biology gradually moved from genomes to proteins and proteomes and to their functionality. Proteomics can potentially capture dynamic changes in protein expression integrating both genetic and epigenetic influences.</p> <p>Methods</p> <p>We prepared primary cultures of epithelial cells from 23 breast cancer tissue samples and performed comparative proteomic analysis. Seven patients developed distant metastases within three-year follow-up. These samples were included into a metastase-positive group, the others formed a metastase-negative group. Two-dimensional electrophoretical (2-DE) gels in pH range 4–7 were prepared. Spot densities in 2-DE protein maps were subjected to statistical analyses (R/maanova package) and data-mining analysis (GUHA). For identification of proteins in selected spots, liquid chromatography-tandem mass spectrometry (LC-MS/MS) was employed.</p> <p>Results</p> <p>Three protein spots were significantly altered between the metastatic and non-metastatic groups. The correlations were proven at the 0.05 significance level. Nucleophosmin was increased in the group with metastases. The levels of 2,3-trans-enoyl-CoA isomerase and glutathione peroxidase 1 were decreased.</p> <p>Conclusion</p> <p>We have performed an extensive proteomic study of mammary epithelial cells from breast cancer patients. We have found differentially expressed proteins between the samples from metastase-positive and metastase-negative patient groups.</p

Students&apos; perception regarding medical education in Nepal

Abstract Background: Medical schools and medical education look different as we advance into the 21st century. Nepal has seen a dramatic increase in the number of medical schools/colleges in the last decade. Most schools practice traditional teaching method while others are implementing problem based learning (PBL). It is important to explore the current advances and practices in medical education to meet the needs of the health services of the country. Objective: The objective of the present study is to explore the students&apos; perception regarding present status of medical education in Nepal and provide recommendations to address future needs. Materials and methods: The study design of the present research was descriptive and exploratory type. Structured Questionnaire was used to assess the students&apos; perception relating to different aspects of medical education. A total of 24 students studying in the fi nal year of MBBS from six medical colleges were selected randomly. Results: The traditional teaching/learning methodologies have been prevailing in the medical schools of the country. PBL suits many objectives of self directed learning (SDL) because students learn to reason and deduce facts and fi gures rather than rote learning. For the success of PBL and SDL students require learning resources and as per our fi ndings although 71% of the students were satisfi ed with library facilities 54% were dissatisfi ed with computer resources. Community based approaches have been focused in the curriculum of all the medical schools of Nepal. About public health and community medicine teaching 86% of the students reported to be appropriate, of which 18% actually thought it was excessive. About the teaching of evidence based medicine (EBM), 50% students felt it was adequate and other half thought it was inadequate. Majority of the students i.e. 62% of the students also felt that the care of ambulatory patients was as well covered as the care of hospitalized patients. The areas of clinical practice which the students felt were inadequate included: nutrition (71%), geriatrics (70%), end of life care (71%), palliative care (67%), long term health care (70%), continuity of care (70%), ethical decision making (56%) and patient follow up (50%). In spite of completing their training, 25% felt they were not confi dent that they had acquired the clinical skills required to begin the residency program. As much as 60% felt they did not receive information about specialities and alternative medical careers. About 75% of the students had the feeling that medical profession will not be fi nancially rewarding; 80% felt it would not be as respectable; 99% felt it would be more scientifi cally challenging. Conclusion: The medical education of Nepal is still guided by the notion of the traditional approaches. The teaching methods should come up as per the advancement in contemporary medical education. The training needs to be more structured and focused in practical reality than only feeding students with theoretical knowledge

Medical Education Medical education and training in Nepal: SWOT analysis

Objective: To analyse the impact of the medical colleges that have been set up within the last two decades by production of the doctors and the effect on the health of the people Materials and methods: SWOT (strength, weakness, opportunities and threats) analysis of medical education in Nepal has been done by reviewing medical manpower produced by the different institutions in the undergraduate and postgraduate (PG) categories, their registration with the Nepal Medical Council in terms of the existing health scenario of the country Results: Shows severe shortage of basic sciences teachers. In the clinical areas ophthalmic manpower and services provided are exemplary. There are shortages and shortcomings in all areas if standard health care is to be provided to the Nepalese. There is a long way to go to provide the expected educational and medical services to foreigners prepared to pay more to avail of this in Nepal. Key words: HRH, undergraduate, PG, basic sciences, clinical, medical tourism. The doctor per population ratio in Nepal of 1992 was 1:15,800 of the population (0.063 per 1000) 1 but now it has reached to 0.24 per 1000 as of 20082

Original Research Article Effect of preloading on haemodynamic of the patient undergoing surgery under spinal anaesthesia

Background: Hypotension and bradycardia after conduction of spinal anaesthesia are common side effects because of sympathetic blockade. Efforts to prevent these complications have been attempted like preloading with crystalloids, colloids or use of vasopressors. The role of volume preloading to prevent haemodynamic changes associated with spinal anaesthesia has been recently questioned. Objective: The objective of the study was to investigate the effects of volume preload on changes of patient’s hemodynamic. Materials and methods: A Quasi- experimental design was used to conduct the study. Taking written informed consent, 40 patients of age group 18-45 years and ASA grade I and II undergoing surgery under spinal anaesthesia in operation theatre of Dhulikhel Hospital were selected as the sample of the study and allocated randomly to 2 groups. Group I did not receive volume preload and Group II received preload of 1000 ml of Ringer’s lactate solution within 30 minutes immediately before giving the spinal anaesthesia. An observational checklist was used to collect demographic, intraoperative and post-operative records of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR). Results: The findings revealed that the haemodynamic changes occurred in all patients. The decrease in SBP, MBP an

Hidden costs of hospital based delivery from two tertiary hospitals in Western Nepal

INTRODUCTION:Hospital based delivery has been an expensive experience for poor households because of hidden costs which are usually unaccounted in hospital costs. The main aim of this study was to estimate the hidden costs of hospital based delivery and determine the factors associated with the hidden costs. METHODS:A hospital based cross-sectional study was conducted among 384 post-partum mothers with their husbands/house heads during the discharge time in Manipal Teaching Hospital and Western Regional Hospital, Pokhara, Nepal. A face to face interview with each respondent was conducted using a structured questionnaire. Hidden costs were calculated based on the price rate of the market during the time of the study. RESULTS:The total hidden costs for normal delivery and C-section delivery were 243.4 USD (US Dollar) and 321.6 USD respectively. Of the total maternity care expenditures; higher mean expenditures were found for food &amp; drinking (53.07%), clothes (9.8%) and transport (7.3%). For postpartum women with their husband or house head, the total mean opportunity cost of "days of work loss" were 84.1 USD and 81.9 USD for normal delivery and C-section respectively. Factors such as literate mother (p = 0.007), employed house head (p = 0.011), monthly family income more than 25,000 NRs (Nepalese Rupees) (p = 0.014), private hospital as a place of delivery (p = 0.0001), C-section as a mode of delivery (p = 0.0001), longer duration (&gt;5days) of stay in hospital (p = 0.0001), longer distance (&gt;15km) from house to hospital (p = 0.0001) and longer travel time (&gt;240 minutes) from house to hospital (p = 0.007) showed a significant association with the higher hidden costs (&gt;25000 NRs). CONCLUSION:Experiences of hidden costs on hospital based delivery and opportunity costs of days of work loss were found high. Several socio-demographic factors, delivery related factors (place and mode of delivery, length of stay, distance from hospital and travel time) were associated with hidden costs. Hidden costs can be a critical factor for many poor and remote households who attend the hospital for delivery. Current remuneration (10-15 USD for normal delivery, 30 USD for complicated delivery and 70 USD for caesarean section delivery) for maternity incentive needs to account the hidden costs by increasing it to 250 USD for normal delivery and 350 USD for C-section. Decentralization of the obstetric care to remote and under-privileged population might reduce the economic burden of pregnant women and can facilitate their attendance at the health care centers

Effect of preloading on haemodynamic of the patient undergoing surgery under spinal anaesthesia

An observational checklist was used to collect demographic, intraoperative and post-operative records of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR). Results: The fi ndings revealed that the haemodynamic changes occurred in all patients. The decrease in SBP, MBP and DBP from baseline was statistically signifi cant at all points of time (p=0.000). The decrease in HR from baseline was not statistically signifi cant at all points of time (p&gt;0.05). The overall incidence of hypotension was 50%, among which 9 (45%) were from without preload group and 11 (55%) were from with preload group. The incidence of hypotension was similar in groups, sexes and surgical conditions (General Surgery, Gynae/Obs and Orthopaedics). There were no signifi cant differences in haemodynamic changes among groups. Conclusion: On the basis of fi ndings, it is concluded that volume preloading had no effect on the incidence of hypotension and bradycardia after spinal anaesthesia

Effect of age and estrogen on biochemical markers of bone turnover in postmenopausal women: a population-based study from Nepal

Bashu Dev Pardhe, Sabala Pathak, Anjeela Bhetwal, Sumitra Ghimire, Shreena Shakya, Puspa Raj Khanal, Sujan Babu Marahatta Department of Laboratory Medicine, Manmohan Memorial Institute of Health Sciences, Kathmandu, Nepal Background: Osteoporosis, a common disease worldwide, is characterized by low bone mass and architectural deterioration of bone tissue, leading to enhanced bone fragility and increase in fracture risks. Both menopause and aging are related factors leading to greater risk of bone disease, particularly among postmenopausal women. Hence, the main purpose of this study was to investigate the differences in biochemical markers of bone turnover and to evaluate the association of hormones and age-related factors with biochemical markers between pre- and postmenopausal women.Methods: A descriptive cross-sectional study was conducted over a period of 6 months among the female population of Dholahity community, Lalitpur, Nepal. A total of 496 healthy women were selected based on the questionnaire strategy. Among them, 244 were premenopausal and 252 were postmenopausal women. Different bone markers were evaluated as per the guideline provided by the reagent manufacturer, and hormonal assay, particularly estradiol level assessment, was performed by chemiluminescence immunoassay-based technique.Results: A significant decrease in serum calcium level and estradiol level was observed in postmenopausal women as compared to premenopausal women, whereas a significant increase in serum phosphorus and alkaline phosphatase (ALP) levels was seen among postmenopausal (p&lt;0.001). Age was significantly correlated with bone markers (ALP and calcium) in postmenopausal group (p&lt;0.005), while there was no significant correlation in premenopausal group. In addition, there was significant positive correlation between calcium and estradiol in postmenopausal women, while ALP was negatively correlated with estradiol in that group. Further, no significant correlation was demonstrated between estradiol and bone markers in postmenopausal women in body mass index and age-adjusted partial correlation analysis.Conclusion: Timely diagnosis of osteoporosis in women would be of significant benefit for effective care for required populations and help to minimize mortality rate and financial burden of our country. Keywords: postmenopause, osteoporosis, bone markers, estradiol, Nepa

Barriers in the access, diagnosis and treatment completion for tuberculosis patients in central and western Nepal: A qualitative study among patients, community members and health care workers

BACKGROUND:Nepal has achieved a significant reduction of TB incidence over the past decades. Nevertheless, TB patients continue to experience barriers in access, diagnosis and completion of the treatment. The main objective of this study was to explore the factors affecting the access to the health services, diagnosis and the treatment completion for TB patients in central and western Nepal. METHODS:Data were collected using in-depth interviews (IDI) with the TB patients (n = 4); Focus Group Discussions (FGDs) with TB suspected patients (n = 16); Semi Strucutred Interviews (SSIs) with health workers (n = 24) and traditional healers (n = 2); and FGDs with community members (n = 8). All data were audio recorded, transcribed and translated to English. All transcriptions underwent thematic analysis using qualitative data analysis software: Atlas.ti. RESULTS:Barriers to access to the health centre were the long distance, poor road conditions, and costs associated with travelling. In addition, lack of awareness of TB and its consequences, and the belief, prompted many respondents to visit traditional healers. Early diagnosis of TB was hindered by lack of trained health personnel to use the equipment, lack of equipment and irregular presence of health workers. Additional barriers that impeded the adherence and treatment completion were the need to visit health centre daily for DOTS treatment and associated constraints, complex treatment regimen, and the stigma. CONCLUSIONS:Barriers embedded in health services and care seekers' characteristics can be dealt by strengthening the peripheral health services. A continuous availability of (trained) human resources and equipment for diagnosis is critical. As well as increasing the awareness and collaborating with the traditional healers, health services utilization can be enhanced by compensating the costs associated with it, including the modification in current DOTS strategy by providing medicine for a longer term under the supervision of a family member, peer or a community volunteer

Health system preparedness for COVID-19 and its impacts on frontline health-care workers in Nepal: a qualitative study among frontline health-care workers and policy-makers

Background: Rapidly growing coronavirus disease 2019 (COVID-19) pandemic has brought unprecedented challenges to the health system in Nepal. The main objective of this study was to explore the health system preparedness for COVID-19 and its impacts on frontline health-care workers in Nepal. Methods: Semi-structured interviews were conducted among 32 health-care workers who were involved in clinical care of COVID-19 patients and four policy-makers who were responsible for COVID-19 control and management at central and provincial level. Interviews were conducted through telephone or Internet-based tools such as Zoom and Skype. All interviews were audio-recorded, transcribed into English, and coded using inductive and deductive approaches. Results: Both health-care workers and policy-makers reported failure to initiate pre-emptive control measures at the early stages of the outbreak as the pivot in pandemic control. Although several measures were rolled out when cases started to appear, the overall health system preparedness was low. The poor governance, and coordination between three tiers of government was compounded by the inadequate personal protective equipment for health-care workers, insufficient isolation beds for patients, and poor engagement of the private sector. Frontline health-care workers experienced various degrees of stigma because of their profession and yet were able to maintain their motivation to continue serving patients. Conclusion: Preparedness for COVID-19 was affected by the poor coordination between three tiers of governance. Specifically, the lack of human resources, inadequate logistic chain management and laboratory facilities for testing COVID-19 appeared to have jeopardized the health system preparedness and escalated the pandemic in Nepal. Despite the poor preparedness, and health and safety concerns, health-care workers maintained their motivation. There is an urgent need for an effective coordination mechanism between various tiers of health structure (including private sector) in addition to incentivizing the health-care workers for the current and future pandemics
