Glutathione depletion in PC12 results in selective inhibition of mitochondrial complex I activity. Implications for Parkinson's disease

Oxidative stress appears to play an important role in degeneration of dopaminergic neurons of the substantia nigra (SN) associated with Parkinson's disease (PD). The SN of early PD patients have dramatically decreased levels of the thiol tripeptide glutathione (GSH). GSH plays multiple roles in the nervous system both as an antioxidant and a redox modulator. We have generated dopaminergic PC12 cell lines in which levels of GSH can be inducibly down-regulated via doxycycline induction of antisense messages against both the heavy and light subunits of gamma-glutamyl-cysteine synthetase, the rate-limiting enzyme in glutathione synthesis. Down-regulation of glutamyl-cysteine synthetase results in reduction in mitochondrial GSH levels, increased oxidative stress, and decreased mitochondrial function. Interestingly, decreases in mitochondrial activities in GSH-depleted PC12 cells appears to be because of a selective inhibition of complex I activity as a result of thiol oxidation. These results suggest that the early observed GSH losses in the SN may be directly responsible for the noted decreases in complex I activity and the subsequent mitochondrial dysfunction, which ultimately leads to dopaminergic cell death associated with PD.

Denitrification and N2O:N2 production in temperate grasslands: processes, measurements, modelling and mitigating negative impacts

In this review we explore the biotic transformations of nitrogenous compounds that occur during denitrification, and the factors that influence denitrifier populations and enzyme activities, and hence, affect the production of nitrous oxide (N2O) and dinitrogen (N2) in soils. Characteristics of the genes related to denitrification are also presented. Denitrification is discussed with particular emphasis on nitrogen (N) inputs and dynamics within grasslands, and their impacts on the key soil variables and processes regulating denitrification and related gaseous N2O and N2 emissions. Factors affecting denitrification include soil N, carbon (C), pH, temperature, oxygen supply and water content. We understand that the N2O:N2 production ratio responds to the changes in these factors. Increased soil N supply, decreased soil pH, C availability and water content generally increase N2O:N2 ratio. The review also covers approaches to identify and quantify denitrification, including acetylene inhibition, (15)N tracer and direct N2 quantification techniques. We also outline the importance of emerging molecular techniques to assess gene diversity and reveal enzymes that consume N2O during denitrification and the factors affecting their activities and consider a process-based approach that can be used to quantify the N2O:N2 product ratio and N2O emissions with known levels of uncertainty in soils. Finally, we explore strategies to reduce the N2O:N2 product ratio during denitrification to mitigate N2O emissions. Future research needs to focus on evaluating the N2O-reducing ability of the denitrifiers to accelerate the conversion of N2O to N2 and the reduction of N2O:N2 ratio during denitrification.

Submandibular salivary gland transfer prevents radiation-induced xerostomia

BACKGROUND

Xerostomia is a significant morbidity of radiation therapy in the management of head and neck cancers. We hypothesized that the surgical transfer of one submandibular salivary gland to submental space, outside the proposed radiation field, prior to starting radiation treatment, would prevent xerostomia.

METHODS

We are conducting a prospective clinical trial where the submandibular gland is transferred as part of the surgical intervention. The patients are followed clinically, with salivary flow studies and University of Washington quality of life questionnaire.

RESULTS

We report early results of 16 patients who have undergone this procedure. Seven patients have finished and 2 patients are currently undergoing radiation treatment. In 2 patients, no postoperative radiation treatment was indicated. Two patients are waiting to start radiation treatment and 2 patients refused treatment after surgery. The surgical transfer was abandoned in 1 patient. All of the transferred salivary glands were positioned outside the proposed radiation fields and were functional. The patients did not complain of any xerostomia and developed only minimal oral mucositis. There were no surgical complications.

CONCLUSIONS

Surgical transfer of a submandibular salivary gland to the submental space (outside the radiation field) preserves its function and prevents the development of radiation-induced xerostomia.

Submandibular gland transfer: a new method of preventing radiation-induced xerostomia

OBJECTIVE

Radiation-induced xerostomia is a significant morbidity of radiation therapy in the management of patients with head and neck cancers. We have recently reported a method of transfer of one submandibular gland to the submental space in a small pilot series of eligible surgical patients. The submental space was shielded during postoperative radiation therapy. The transferred gland continued to function after the completion of radiation therapy and none of the patients developed xerostomia. The purpose of this article is to present the technique of submandibular gland transfer in detail and to evaluate the postoperative survival and function of the transferred submandibular glands.

DESIGN

Prospective clinical trial.

METHODS

The submandibular gland was transferred on eligible patients as part of their surgical intervention. The patients were followed clinically, with salivary flow and radioisotope studies.

RESULTS

We performed the surgical transfer of the submandibular salivary gland in 24 of 25 patients placed on the protocol. All the glands survived transfer and functioned well postoperatively as demonstrated on the salivary flow and the radioisotope studies. The surgical transfer was relatively simple and added 45 minutes to the surgical procedure. There were no complications attributed to the submandibular gland transfer.

CONCLUSIONS

We have successfully demonstrated that the submandibular gland can be surgically transferred to the submental space with its function preserved. The gland seems to continue functioning even after radiation therapy with the appropriate shielding. This surgical transfer procedure has the potential to change the way we currently manage patients with head and neck cancer.

Does radiotherapy have a role in hemangiopericytoma management? Report of 14 new cases and a review of the literature

From 1948 to 1984, 14 adult patients received radiation therapy as a part of their treatment for hemangiopericytoma at the University of Texas M.D. Anderson Hospital and Tumor Institute at Houston. In addition to radiation therapy 11 patients were treated with surgery, with or without chemotherapy--5 as primary management and 6 after recurrence following surgical excision. Although 9 of these 11 patients had macroscopic and 1 had definite microscopic disease at the time of irradiation, none suffered local recurrence and 9 have survived from 3.5 years to 20 years free of disease. Two of the 11 patients died of distant metastases. Two patients completed treatment for palliation and 1 of them survived for 2 years after treatment. The results suggest that postoperative radiation therapy should be considered as an integral part of the primary treatment of hemangiopericytoma.

Automated Detection of TMJ Osteoarthritis Based on Artificial Intelligence

The purpose of this study was to develop a diagnostic tool to automatically detect temporomandibular joint osteoarthritis (TMJOA) from cone beam computed tomography (CBCT) images with artificial intelligence. CBCT images of patients diagnosed with temporomandibular disorder were included for image preparation. Single-shot detection, an object detection model, was trained with 3,514 sagittal CBCT images of the temporomandibular joint that showed signs of osseous changes in the mandibular condyle. The region of interest (condylar head) was defined and classified into 2 categories-indeterminate for TMJOA and TMJOA-according to image analysis criteria for the diagnosis of temporomandibular disorder. The model was tested with 2 sets of 300 images in total. The average accuracy, precision, recall, and F1 score over the 2 test sets were 0.86, 0.85, 0.84, and 0.84, respectively. Automated detection of TMJOA from sagittal CBCT images is possible by using a deep neural networks model. It may be used to support clinicians with diagnosis and decision making for treatments of TMJOA.

Primary pericardial synovial sarcoma: a case report and literature review

Primary synovial sarcoma of the heart is a rare tumor, with only six previous cases having been reported in the literature. Treatment has included surgery with or without chemotherapy. We present the first case of a documented synovial sarcoma arising from the pericardium in a 19-year-old man. Molecular analysis for t(X; 18) SYT-SSX gene fusion was positive. Radiation treatment was given postoperatively to the entire heart with a boost to the area where the margins were positive.

Caspase 3 inhibition attenuates hydrogen peroxide-induced DNA fragmentation but not cell death in neuronal PC12 cells

Exposure of neurons to H(2)O(2) results in both necrosis and apoptosis. Caspases play a pivotal role in apoptosis, but exactly how they are involved in H(2)O(2)-mediated cell death is unknown. We examined H(2)O(2)-induced toxicity in neuronal PC12 cells and the effects of inducible overexpression of the H(2)O(2)-scavenging enzyme catalase on this process. H(2)O(2) caused cell death in a time- and concentration-dependent manner. Cell death induced by H(2)O(2) was found to be mediated in part through an apoptotic pathway as H(2)O(2)-treated cells exhibited cell shrinkage, nuclear condensation and marked DNA fragmentation. H(2)O(2) also triggered activation of caspase 3. Genetic up-regulation of catalase not only significantly reduced cell death but also suppressed caspase 3 activity and DNA fragmentation. While the caspase 3 inhibitor DEVD inhibited both caspase 3 activity and DNA fragmentation induced by H(2)O(2) it did not prevent cell death. Treatment with the general caspase inhibitor ZVAD, however, resulted in complete attenuation of H(2)O(2)-mediated cellular toxicity. These results suggest that DNA fragmentation induced by H(2)O(2) is attributable to caspase 3 activation and that H(2)O(2) may be critical for signaling leading to apoptosis. However, unlike inducibly increased catalase expression and general caspase inhibition both of which protect cells from cytotoxicity, caspase 3 inhibition alone did not improve cell survival suggesting that prevention of DNA fragmentation is insufficient to prevent H(2)O(2)-mediated cell death.

Association of breast cancer with meningioma. A report of five cases

Five patients with diagnosed breast cancer who developed meningiomas are reported. The literature contains reports of an additional 25 such patients. Some authors have noted hormonal sensitivity and the presence of hormone receptors in some meningiomas. Because breast cancer is a common tumor of women, it is probable that any association between breast cancer and meningioma is fortuitous. Two patients in this small series each had a sister with breast cancer, one of them also had three other first-degree relations with colon cancer. Three of the patients had other tumors as well as breast cancer. It is important to fully investigate brain lesions in patients with breast cancer so that potentially curable meningiomas are not mistaken for metastases.

Swine-origin influenza A (H1N1) in Indian children

BACKGROUND

Swine-origin influenza A H1N1 (S-OIV) has not been systematically studied in Indian children.

OBJECTIVES

To study the clinical characteristics, morbidity and mortality pattern in children with S-OIV infection.

METHODS

This prospective study was conducted during the 'containment phase' of the pandemic in New Delhi from 10 June to 5 August 2009. All children suspected of being infected by S-OIV were admitted to the isolation wards and clinically evaluated according to WHO guidelines. Nasal and throat swabs were collected immediately for real-time reverse transcriptase polymerase chain reaction (RT-PCR). Haemoglobin, total leucocyte and platelet counts and chest radiography were undertaken in all patients. Those who tested positive for S-OIV infection were treated with oseltamivir for 5 days in isolation wards.

RESULTS

Thirty-seven children fulfilled the inclusion criteria. Twenty-one tested positive for S-OIV by RT-PCR and 16 tested negative. Comparison of the clinical characteristics of the two groups showed that duration of cough was longer in children with S-OIV (p<0.03). Total leucocyte and lymphocyte counts were significantly less in the S-OIV group (p<0.001 and , 0.02, respectively). Oseltamivir-related gastritis was seen in 38% of children. All improved and were discharged.

CONCLUSION

S-OIV infection in Indian children had features similar to those of seasonal influenza. Lymphopenia is an important feature of S-OIV.

An epidemiological study of injury among urban population

BACKGROUND

Injuries are a focus of public health practice because they pose a serious health threat, occur frequently and are preventable. Injuries affect people of all ages and range from minor cuts and bruises to major catastrophes that take thousands of lives.

OBJECTIVES

This paper aims to fi nd out the prevalence of injuries and to study the various epidemiological factors related to the injuries in Dharan.

MATERIALS AND METHODS

A sample of 1398 households was taken as study sample. A systematic random sampling technique was used to select the 10% households from each 19 wards. A pre-tested questionnaire was used to collect demographic information and information related to injuries to the persons suffered from injuries.

RESULT

The prevalence of minor injury in Dharan was 3.5% per month. The injury was common in the age group, 40-49 years (4.6%) and majority of injured persons were farmers (6.9%). Home was the common place (55.6%) for the minor injury. Cut/stab (32.8%) was the most common types of minor injury. The prevalence of major injury was 0.7% per year and occurred more among 50-59 years age group (1.7%). The commonest place for major injury was at road (53.1%) and service holders were at more risk (1.4%). Falls from the height (46.9%) were the most common types of major injury.

CONCLUSION

The injuries related to lifestyle profession and road traffic accidents (RTA) is the commonest burden revealed in the study sample. Promotion of safety and education for protection at work and safe driving can prevent the major socio-economic loss to the family and community at large.

Aetioepidemiological profile of spinal injury patients in Eastern Nepal

This is a retrospective case series of 233 spinal injury patients admitted to the orthopaedic ward of BPKIHS from May 1997 to April 2001. The inpatient records were analysed. In all, 40.3% of spinal injuries resulted from falls from trees while cutting leaves for fodder, and 27.9% resulted from falls from first/second floors. More than 75% of total spinal injuries are largely preventable. Overall, 46.8% of our spinal injury patients had complete cord transection at the level of injury. All adolescents and adults, irrespective of age or sex, should be the target groups for community education and intervention programmes for prevention of spinal injury.

Concurrent weekly carboplatin and radiotherapy for nasopharyngeal carcinoma: report of a joint phase II study

We report a phase I/II study of weekly concurrent carboplatin and radiotherapy in patients with nasopharyngeal carcinoma (M0 stage). Of 47 patients registered, 45 completed the treatment course. Twenty-six (55%) (95% CI, 41-69%) patients experienced > or =grade 3 acute toxicity (RTOG). Five (11%) (95% CI, 2-20%) patients experienced > or =grade 3 chronic toxicity. This regimen appears to have acceptable toxicity compared to the experimental arm of Phase III Intergroup Study 0099, but progression-free and overall survival are probably inferior. At present, there is no data to suggest that carboplatin can replace cisplatin for concurrent chemoradiation for NPC.

Effect of Irradiance and Exposure Duration on Temperature and Degree of Conversion of Dual-Cure Resin Cement for Ceramic Restorations

This study investigated the effects of irradiance and exposure duration on dual-cured resin cements irradiated through ceramic restorative materials. A single light-curing unit was calibrated to three different irradiances (500, 1000, and 1500 mW/cm²) and irradiated to three different attenuating materials (transparent acryl, lithium disilicate, zirconia) with 1-mm thicknesses for 20 or 60 seconds. The changes in irradiance and temperature were measured with a radiometer (or digital thermometer) under the attenuating materials. The degree of conversion (DC) of dual-cure resin cement after irradiation at different irradiances and exposure durations was measured with Fourier transform near infrared spectroscopy. Two-way analysis of variance revealed that irradiance ( p<0.001) and exposure duration ( p<0.001) significantly affected temperature and DC. All groups showed higher DCs with increased exposure times ( p<0.05), but there were no statistically significant differences between the groups irradiated with 1000 mW/cm² and 1500 mW/cm² ( p>0.05). Higher-intensity irradiances yielded higher temperatures ( p<0.05), but exposure time did not affect temperature when materials were irradiated at 500 mW/cm² ( p>0.05).

Optic nerve sheath fenestration for a reversible optic neuropathy in radiation oncology

To the authors' knowledge, there is a paucity of published accounts of management of radiation-induced optic neuropathy (RION) by optic nerve sheath fenestration (ONSF) in the conventional medical literature. With higher doses of radiation being given by using conformal techniques, more radiation-induced optic neuritis and neuropathy will be identified. We report here the successful use of ONSF to restore vision to three consecutive patients with pending anterior RION, and the importance of early identification and intervention in these potentially reversible cases.

Factors affecting Early Age Marriage in Dhankuta Municipality, Nepal

Background: Child marriage is a substantial barrier to social and economic development in Nepal, and a primary concern for women’s health. Little evidence from Nepal is available regarding the ways in which early marriage may compromise young women’s lives and their reproductive health and choices. The objectives of this study was to find out the factors associated with early age marriages in Dhankuta Municipality. Methods: The cross-sectional study was conducted among the residents of Dhankuta municipality, Nepal; where 246 households were taken as subjects. Pretested semi-structured questionnaire was administered to the study subjects and face to face interview was conducted. Chi-square test was applied to find out the association between factors and age of marriages. Results: Almost 53.3% of women were married before age 18 years. Education of wife and husband, and economic status are found to be the important variables in explaining early age marriage. Prevalence of child marriage was higher in Hindu than in Buddhist and Christian women but the difference was not significant. Age of marriage was not significantly associated with contraceptive use. Unwanted pregnancies were higher in early age marriage. It was also seen that unwanted pregnancies was higher (59.3%) than wanted pregnancies (48.6%). Conclusion: The findings of the study indicate that early age marriage was associated with low education and being poor.

Knowledge, Attitude and Practice Regarding Pharmacovigilance and Consumer Pharmacovigilance among Consumers at Lalitpur District, Nepal

BACKGROUND

Adverse drug reactions (ADRs) can be a big threat to the health of people in Nepal as a variety of medicines are consumed in the country. Involving consumers in pharmacovigilance can strengthen ADR reporting. The study aims to find out knowledge, attitude and practice regarding pharmacovigilance and consumer pharmacovigilance among consumers at Lalitpur district, Nepal Methods: It was carried out in outpatients visiting in KIST Medical College and Teaching Hospital, Lalitpur, Nepal. Participant's knowledge, attitude and practice were measured by noting their agreement with a set of 21 statements along with multiple choice and open ended questions.

RESULTS

A total of 157 outpatients were surveyed. The knowledge scores for males (12) was better compared to the females (11), but the scores for attitude and practice were same for both groups. The maximum score for knowledge was 29, attitude was 6 and practice was 10. The overall KAP scores was 45. The total scores for knowledge, attitude and practice for males (24) were better compared to female (22) respondents. Seventy-one patients (68%) who participated in this study favoured establishing a consumer centre for obtaining information about ADRs.

CONCLUSIONS

Knowledge scores among consumers regarding pharmacovigilance is low and require advocacy and improvement.

Subglottic stenosis secondary to extramedullary hematopoiesis in a patient with postpolycythemia myeloid metaplasia

BACKGROUND

Extramedullary hematopoiesis (EMH) is known to occur in myeloproliferative disorders and hemoglobinopathies and is usually seen in the spleen and liver.

METHODS

We report the first case of EMH causing subglottic stenosis in a woman with postpolycythemia myeloid metaplasia (PPMM). A tracheotomy was performed to maintain the airway and local radiotherapy was given.

RESULTS

Two months after the radiotherapy was completed laryngoscopy showed an unobstructed airway with no evidence of disease, and the patient was successfully decanulated. Magnetic resonance imaging 8 months after radiotherapy confirmed the absence of local disease.

CONCLUSION

Consideration should be given to EMH as a possible cause of airway obstruction in the differential diagnosis of a patient with a history of PPMM.

Adverse drug reaction reporting in a pharmacovigilance centre of Nepal

BACKGROUND

Pharmacovigilance is the "science and activities relating to the detection, assessment, understanding and prevention of adverse effects or any other drug related problems". Nepal joined the international pharmacovigilance programme as a full member in 2007. KIST Medical College, Lalitpur, Nepal joined the national programme as a regional centre from mid-July 2008. Currently, the pattern and scope of adverse drug reactions (ADRs) in Nepal remains unexplored.

AIMS

To observe and analyse the pattern of ADRs at KIST Medical College, Lalitpur, Nepal.

METHOD

A retrospective analysis of all ADRs reported to the centre from mid July 2008 to July 2011 was performed. Data was analysed for ADR severity, causality, and preventability.

RESULTS

A total of 113 ADR reports were obtained from various clinical departments. The maximum number of reactions was due to antimicrobials, followed by anti-hypertensives and NSAIDs.

CONCLUSION

Antimicrobials were the commonest group of drugs causing ADRs and the most commonly seen ADR was maculopapular rash followed by diarrhea and vomiting.

Rain, temperature, and child-adolescent height among Native Amazonians in Bolivia

BACKGROUND

Global climate change and recent studies on early-life origins of well-being suggest that climate events early in life might affect health later in life.

AIM

The study tested hypotheses about the association between the level and variability of rain and temperature early in life on the height of children and adolescents in a foraging-farming society of native Amazonians in Bolivia (Tsimane').

SUBJECT AND METHODS

Measurements were taken for 525 children aged 2-12 and 218 adolescents aged 13-23 in 13 villages in 2005. Log of standing height was regressed on mean annual level and mean intra-annual monthly coefficient of variation (CV) of rain and mean annual level of temperature during gestation, birth year, and ages 2-4. Controls include age, quinquennium and season of birth, parent's attributes, and dummy variables for surveyors and villages.

RESULTS

Climate variables were only related with the height of boys age 2-12. The level and CV of rain during birth year and the CV of rain and level of temperature during ages 2-4 were associated with taller stature. There were no secular changes in temperature (1973-2005) or rain (1943-2005).

CONCLUSION

The height of young females and males is well protected from climate events, but protection works less well for boys ages 2-12.

Academic detailing

There are a number of sources available to prescribers to stay up to date about medicines. Prescribers in rural areas in developing countries however, may not able to access some of them. Interventions to improve prescribing can be educational, managerial, and regulatory or use a mix of strategies. Detailing by the pharmaceutical industry is widespread. Academic detailing (AD) has been classically seen as a form of continuing medical education in which a trained health professional such as a physician or pharmacist visits physicians in their offices to provide evidence-based information. Face-to-face sessions, preferably on an individual basis, clear educational and behavioural objectives, establishing credibility with respect to objectivity, stimulating physician interaction, use of concise graphic educational materials, highlighting key messages, and when possible, providing positive reinforcement of improved practices in follow-up visits can increase success of AD initiatives. AD is common in developed countries and certain examples have been cited in this review. In developing countries the authors have come across reports of AD in Pakistan, Sudan, Argentina and Uruguay, Bihar state in India, Zambia, Cuba, Indonesia and Mexico. AD had a consistent, small but potentially significant impact on prescribing practices. AD has much less resources at its command compared to the efforts by the industry. Steps have to be taken to formally start AD in Nepal and there may be specific hindering factors similar to those in other developing nations.

Alcohol Use among Women in a Town of Eastern Nepal

A community-based cross-sectional survey with cluster sampling method (probability proportionate to size) was carried out to estimate the prevalence of alcohol consumption among Nepalese women in Dharan town to assess the pattern of use and to identify the factors associated with this habit. A representative sample of 2340 women, aged 15 years and above was interviewed in 2002. The estimated prevalence of alcohol consumption was nearly 17%. Alcohol use is prevalent among females of hill ethnic groups. Nearly half of the divorced (formal or informal) women consumed alcohol. The women, aged 50 years and above, were at risk to become addicted to its use. Most popular drink in this area is a homemade product (Local Raksi). The alcohol users are more likely to smoke as well. More than 9% of pregnant women are found to consume alcohol during their pregnancy. Effective awareness programs are required to discourage the excessive use of alcohol among women and encourage those seeking regular health care services.Key Words: Prevalence, pattern, factors, women, alcohol, Dharan, Nepal.

Primary Heealth Care Development: Where is Nepal after 30 years of Alma Ata Declaration??

The year 2008 has witnessed the global conversation to return to tenets of Alma-Ata and to review its 30 years of journey. We reviewed Nepal's journey on Primary Health Care development: policy formulation, structure development, progress and constraints. Though Nepal has institutionalised the PHC approach in health policy, strategy and health care delivery system, this has not been effectively translated into actions, and the results are mixed. Nepal has gained impressive achievements in selective primary health care markers: 45.43% maternal mortality and 62.34% child mortality reduction during 1990-2005. But gain in comprehensive health care markers is not impressive: 18.7% Skilled Birth Attendant (4% in poorest quintile and 45% in richest quintile), 39% having access to improved sanitation and 55.7% of females are literate as compared to males. Socio-political environment until recently was not favourable for comprehensive primary health care, allowing limited health sector decentralisation and community empowerment. Health activities were focussed more on selective health care strategy in the form of disease control, immunisation, vitamin A supplementation, oral rehydration solution use and contraceptive use. Nepal's rural hilly geography posed great challenge on logistic supply, communication and retention of health workers rendering public health centres of low quality with negative perceptions of consumers. Nepal is on the pathway to build equitable comprehensive primary health care.

Anemia in pregnancy and its associated factors: A study from Eastern Nepal

Background  Anemia in pregnancy is responsible for many adverse effects on maternal and fetal outcome. It is the commonest hematological disorder accompanying pregnancy. Prevalence of anemia among pregnant women is fairly high worldwide, especially in developing countries. A research finding published by World Health organization revels that the prevalence of anemia among pregnant women in developing countries averages 56% (ranging between 35 to 100%). Though Nepal has decreasing trend of prevalence of anemia, it is still high (42% in 2006). Identifying the associated factors which are responsible for the development of anemia during pregnancy would be of great help in mitigating the burden to some extent. Ojective of the study was to find out the pattern of anemia and associated risk factors for anemia during pregnancy. Materials and Methods A cross-sectional study was conducted in VDC named Hansposa.  Door to door survey was carried out to collect data using pre-designed questionnaires. Ante-natal check-ups were provided with analysis of hemoglobin levels, in every individual of study population, using conventional Shali's method. Chi-square test was applied, where applicable. Results Altogether 249 pregnant women were included in the study. The proportion of anemia was found to be 46.6%, the cases of mild anemia, and moderate anemia were 51.0% and 49.0% respectively. Risk factors includes: history of complications during previous pregnancy (P<0.001), education (P<0.05), age at marriage (P=0.028), low socio-economic status (P<0.001), gravidity and parity (P<0.01), poor knowledge about anemia (P<0.001), abnormal body mass index (P<0.001) and smoking (P=0.05). Conclusion This study indicates that the prevalence of anemia during pregnancy bears a resemblance to national value. Major associated risk factors include: history of complications during previous pregnancy, low knowledge about anemia in pregnant women, women with low body mass index, age at marriage, socio-economic status, gravidity and parity, and smoking. Most importantly, the lack of commitment in female education plays vital role in its existence.DOI: http://dx.doi.org/10.3126/nje.v4i4.11358 Nepal Journal of Epidemiology 2014; 4(4):386-92
