Background: Renal ischemia/reperfusion injury (RIRI) is the most common cause of acute kidney injury. We tested the protective role of endothelin-1 receptor blocker; bosentan (BOS) in animal model of RIRI in two different genders. Methods: Male and female Wistar rats were assigned as sham operated (sham), control group (ischemia), and case group (ischemia + BOS) treated with BOS (50 mg/kg) 2 h before bilateral kidney ischemia induced by clamping renal vessels for 45 min followed by 24 h of renal reperfusion. Results: The RIRI significantly increased the serum levels of blood urea nitrogen and creatinine in both genders (P < 0.05). These values were significantly decreased by BOS in both genders. In male rats, the serum levels of malondialdehyde in the ischemia + BOS group were decreased significantly when compared with ischemia group (P < 0.05). Conclusions: BOS can be used in both genders to attenuate kidney ischemia injury possibly due to its effect in the renal vascular system.

Background: The major objectives of this study were to evaluate the existing primary health care service provisions in the public and private sector and utilization of the services, and to assess the existing manpower and material resources. Methods: Data were collected through interviews with the primary health care providers. Data were also collected from the records maintained at the polyclinics and the Ministry of Health Statistics. An analysis and discussion of all the available data was conducted to develop a comprehensive primary health care service utilization and resources inventory at the polyclinics. Similar data were collected from the primary care providers in the private sector. Results: In the public sector, there are 8 polyclinics that provide primary health care to the children. All the polyclinics have immunization services and curative acute care. Some of the polyclinics have a range of services, including dental care, eye care, and rehabilitative care services that common to both adults and children. In the private sector, primary health care is delivered through the 76 private office and of the individual physicians and 11 grouped private practices. All of the private offices and group practices have curative acute care for children and some of the offices have immunization services. Over all 87.5% of all the immunizations were done at the polyclinics. Over all 60.1% of acute care visits were to the private sector and 39.9% to the public sector. In the public sector, 59.5% were under 5 years children while 40.5% were 5 years or older. The corresponding figures in the private care settings were 80.9% and 11.9%. Conclusions: The findings demonstrate the complimentary role of the public and the private sector in the primary health care of children in this country. While the private sector has a major role in the curative acute care of children, the public sector plays a pivotal role in the immunization services.

Background: This study was conducted to explore the prevalence of medical error underreporting and associated barriers. Methods: This cross-sectional study was performed from September to December 2012. Five hospitals, affiliated with Hamadan University of Medical Sciences, in Hamedan,Iran were investigated. A self-administered questionnaire was used for data collection. Participants consisted of physicians, nurses, midwives, residents, interns, and staffs of radiology and laboratory departments. Results: Overall, 50.26% of subjects had committed but not reported medical errors. The main reasons mentioned for underreporting were lack of effective medical error reporting system (60.0%), lack of proper reporting form (51.8%), lack of peer supporting a person who has committed an error (56.0%), and lack of personal attention to the importance of medical errors (62.9%). The rate of committing medical errors was higher in men (71.4%), age of 50-40 years (67.6%), less-experienced personnel (58.7%), educational level of MSc (87.5%), and staff of radiology department (88.9%). Conclusions: This study outlined the main barriers to reporting medical errors and associated factors that may be helpful for healthcare organizations in improving medical error reporting as an essential component for patient safety enhancement.

Background: Estimating the prevalence of prehypertension and its risk factors in a population becomes important to design preventive measures and hence reduce the burden of hypertension.The aim of this study was to estimate the prevalence of prehypertension and determine the factors associated with hypertension. Methods: This is a cross-sectional study and was carried out in a rural population. The study included 402 participants. Data regarding basic demographic characteristics were collected along with anthropometric measurements including height and weight. Information regarding smoking alcohol intake, dietary habits were collected. Prehypertension was defined as systolic blood pressure 120-139 mm Hg and/or diastolic blood pressure 80-89 mm Hg. Chi-square-test was used to find the association of various risk factors; t-test was used to compare the means. Multiple linear regression analysis was used to know the relationship of various risk factors. Results: Prevalence of prehypertension was estimated to be 28.8%. Factors such as salt intake, tobacco consumption, alcohol consumption, stress, family history of hypertension, history of diabetes mellitus had a significant association with prehypertension (P < 0.05). Conclusions: The prevalence of prehypertension was found to be high among the rural population. Early intervention is needed to decrease the burden of hypertension and its complications in future.

Background: Diabetes is the most prevalent metabolic disease with a growing spread rate in word wide. Short message service (SMS) is of the most common public communication networks, which have brought about a broad spectrum of applications like social, cultural and service products in the late decade. The objective of this research is, the investigate of using SMS on diabetes patients self-caring. Methods : In an interventional study, 228 diabetes patients have been selected from a community charity. With using of random sampling method, they were divided into two groups of 114 subjects as the control and case. The case group was sent messages reminding them about sports, caring foot, taking insulin and oral tablet for 4 weeks via mobile phone. After 4 weeks, a posttest questionnaire was completed. The data analysis was performed using a descriptive statistic, Chi-square, independent t-test, and paired t-test. Results: There are not significant differences between case and control groups before intervention by studied dependent variables (P > 0.05). Performance score mean of taking care of foot, sport and taking oral tablet and insulin in case group before intervention were 29.90, 10, 11.16 and 3.75 respectively and after intervention were 20.11, 41.36, 13.09 and 4.90, respectively. Furthermore, the performance scores mean difference after intervention, taking care of foot (P < 0.001), sport (P < 0.001), taking oral tablet (P = 0.020) was meaningful in case and control groups. Conclusions: Regarding the study results on using cell phone, to utilize virtual training methods is recommended as an appropriate procedure for different health care, self-caring and follow-up training plans for various groups in society, especially diabetic and chronic patients.

Background: Bilateral ureteral obstruction (BUO) affects renal function adversely. Previous investigations have implied that nitric oxide (NO) improves renal function in obstructive nephropathy. The aim of the current study was to investigate the role of NO precursor, L-arginine, and NO blocker agent, L-NAME on kidney tissue damage in rats after 24 h of BUO. Methods: Forty Wistar rats (18 male, 22 female) were divided into four groups as follows; group 1: Sham or negative control group that received saline 3 days prior to the sham operation, group 2: Vehicle or positive control group that received saline 3 days prior to BUO, and groups 3 and 4: L-arginine and L-NAME groups that were treated same as group 2 except L-arginine (300 mg/kg) and L-NAME (4 mg/kg) instead of saline, respectively. Twenty-four hours after obstruction, the serum levels of blood urea nitrogen (BUN), creatinine (Cr), nitrite, and malondialdehyde (MDA) as well as kidney tissue levels of nitrite and MDA were measured and histopathological studies were done on left kidney. Results: The serum levels of BUN and Cr and kidney and body weights increased and the tissue levels of MDA and nitrite decreased significantly in all BUO groups (P < 0.05). However, the tissue damage score was significantly lower in the L-arginine treated group in comparison to the vehicle and L-NAME groups (P < 0.05). As expected, the serum level of nitrite significantly increased in the L-arginine group (P < 0.05). Conclusions: Endogenous NO donor; L-arginine, may protect the kidney tissue against BUO. However, this renoprotective role of L-arginine did not attenuate the increased kidney function markers (BUN and Cr) induced by obstruction.

Background: Obesity is commonly regarded as a risk factor for asthma development, poor asthma control, and poor response to asthma therapy. Methods: In a cross-sectional study, 85 asthmatics (37 male and 48 female) participated. Pulmonary function tests (PFTs) and anthropometric parameters were measured for each patient. Results: Mean age and median duration were 43.9 ± 10.61 and 6 (3-14) years, respectively. Among anthropometric parameters, only waist-to-hip ratio (WHR) indicated significant correlation with PFTs in both sex (P < 0.05). There were negative associations between waist circumference, hip circumference and WHR with PFTs only in overweight and obese women (P < 0.05). Conclusions: Some anthropometric parameters affected lung function, and it seems that gender differentially contributes to this effect.

Background: The 1978 declaration (Alma-Ata declaration) made at the International Conference on Primary Health Care, meeting in Alma-Ata highlighted the critical role played by Community Health Workers (CHWs) to link communities to the health system. The flagship program of Government of India proposed introduction of CHWs namely Accredited Social Health Activist (ASHA). As a link between community and health system ASHA is in a unique position to generate awareness on tobacco-related issues. However, there is limited evidence on practices of ASHAs in tobacco control in India. The present study explores whether CHWs such as ASHAs can be utilized as a resource for informing and educating community on tobacco and its harmful effects. The study captured perceptions and practices of ASHAs regarding tobacco control. Methods: The study was a cross-sectional study conducted among 512 ASHAs in six intervention districts each in Gujarat and Andhra Pradesh. The study settings (i.e., health facilities and villages) were selected through systematic random sampling. The study participants were selected through simple random sampling. Responses were captured through self-administered questionnaire. Logistic regression model was applied to measure associations between variables such as knowledge level of ASHAs and information provided on different tobacco-related diseases by them in both the states, with statistical significance based on the Chi-square test. Results: Our findings indicate that ASHAs linked tobacco usage to diseases such as respiratory problems, lung cancer, tuberculosis, and oral disease. Only one-third of ASHAs reported informing all patients about the harmful health effects of tobacco, whereas more than half of them reported providing information only to patients suffering from specific illness. ASHAs who reported having received training in tobacco control were about Two times more likely to give information on effects of tobacco on respiratory diseases (odds ratio [OR]-1.5; confidence interval [CI]: 1.1-2.4) and adverse reproductive outcomes (OR-2.1; CI: 1.1-20.2). Conclusions: Study findings reflect suboptimal engagement of ASHAs in providing information pertaining to specific tobacco-related diseases. There is an urgent need to sensitize and train ASHAs in appropriate tobacco control practices.

Background: Stress among diabetic patients is much more as compared to normal individuals. A delayed recognition of stress undoubtedly worsens the prognosis for survival for many diabetic patients. Hence, this study was planned to develop an intervention model for the reduction of stress among diabetic patients and to evaluate the developed intervention model in the proposed group. Methods: This study was conducted in endocrinology outpatient department of a tertiary care hospital. Starting at random, the patients were allocated to control group and test group. Controls were given printed educational materials. Test group were counseled with intense lifestyle education using both printed materials and computers; they were contacted by telephones by the investigator every 3 weeks for 3 months and SMS were sent every week containing some educational tips. Results: Mean age was 54 ΁ 11.5 years overall ranging from 30 years to 80 years. About two-third of participants were males with similar distribution in both the groups (intervention = 66%, control = 64%). Half (50%) of the participants lived in joint families, followed by nuclear families (40%). Most (83%) were married and with either graduate or above graduate education (n = 39%). No significant difference was observed in socio-demographic characteristics among both control and intervention groups (P > 0.05). The average stress scores were similar (18.9) at baseline for control and intervention arms. At 3-month follow-up, however, these scores reduced to 17.05 in the intervention arm while they increased to 20.7 in the control arm. At 3 months follow-up, higher proportion of stress reduction was seen in the intervention group. Conclusions: Intervention in the form of intensive lifestyle education and phone calls and SMS significantly decrease their stress score. Mobile-based education has great potential to improve their mental status and increase patient-provider communication, and to decrease stress.

Background: Under-reporting of adverse drug reactions (ADRs) by the prescribers is a common public health problem. Monitoring of factors that influence ADR reporting will reduce risks associated with drug use; improve patients care, safety and treatment outcome. The aim of this study was to determine the factors associated with the reporting of ADRs by health workers in Nnewi Nigeria. Methods: A cross-sectional study of 372 health workers in different health facilities in Nnewi North Local Government Area of Anambra state, selected using multistage sampling technique was done. Data collection employed pretested, self-administered structured questionnaires. Data were analyzed using Statistical Package for Social Sciences version 17. Tests of statistical significance were carried out using Chi-square tests for proportions. A P < 0.05 was considered significant. Results: Out of the 372 respondents studied, 255 (68.5%) were females, and 117 (31.5%) were males. The modal age range (37.6%) was 31-40 years. Factors related by the respondents to influence ADR reporting include: Unavailability of electronic reporting (83.6%), unavailability of reporting forms (66.4%) and ignorance (58.2%). The difference among medical practitioners who related unavailability of electronic reporting process as obstacle to ADR reporting was not significant (P = 0.18). Conclusions: The study results revealed the factors associated with the reporting of ADRs among health workers in Nnewi Nigeria. It is desirable to initiate electronic reporting process, training programs on ADR reporting and make reporting forms/guidelines available to relevant health workers.

Background: Global burden of cancer is on rise and trends and pattern of cancers are rapidly changing different geographic and population groups. Gall bladder cancers are emerging with increasing proportion among select areas and groups and understanding these variations are important for appropriate strategies and interventions. However, absence of a well-developed universal cancer registry system in India, institution based secondary data analysis can generate useful information. The present study was conducted to determine the trend and pattern of cancer cases (with special reference to gall bladder cancer) treated in a tertiary care hospital in northern part of West Bengal. Methods: Record based cross-sectional study was conducted in Department of Radiotherapy, North Bengal Medical College and Hospital. All newly registered cases between (2010 and 2012) were reviewed. Results: A total of 2058 cancer cases were recorded during the 3-year period. Of these, major types of cancers were oro-pharynx (16.1%), breast (15.4%), cervix (13.2%), lung (12.7%), gall bladder (6.5%) stomach cancer (6.4%), etc., Increasing proportions was observed for breast and gall bladder cancers. The proportion of gallbladder cancer cases in 2010, 2011, and 2012 were 3.8%, 7.3% and 7.8%, respectively. Among 134 gall bladder cancer cases, 93.3% were females, 85.1% alcoholics, 57.4% had a history of fatty liver, 94% had adeno/adenosquamous carcinomas, and 65.7% were metastatic in nature. Conclusions: Increasing trend is observed in gall bladder cancer cases emphasizing the need for further large scale studies.

Background: Early detection and treatment of diabetes mellitus may reduce the burden of diabetes and its complications. Screening of undiagnosed diabetes with gingival blood sample in patients attending to the dental hospital and to check the reliability with standard method. Methods: Five hundred and fifty new patients age ranged from 30 to 50 years were randomly selected. Of 550 patients examined, gingival blood samples of 454 patients were collected from bleeding site and analyzed with self-monitoring device. Blood glucose values were recorded. In addition, all the patients were advised for the second visit with overnight fasting for fasting Blood glucose assessment. Among them, 442 patients returned for fasting blood glucose assessment in laboratory with blood glucose analyzer. Results: In the total of 454 patients gingival blood glucose assessment with self-monitoring device, 64 patients showed ≥200 mg/dL, which indicates diabetes, and the other 390 patients showed ≤200 mg/dL, which indicates patients are not diabetic. Whereas, the results of the laboratory blood glucose analysis, 24 (5.43%) patients showed ≥126 mg/dL, 36 (8.14%) patients showed 100-125 mg/dL and the other 382 patients are not diabetic. Comparison of blood glucose measurements by two methods showed sensitivity 96.66% and specificity 99.47%. Conclusions: The results of the present study showed blood obtained from periodontal pocket probing is a reliable sample to screen diabetes in periodontal disease population. Early diagnosis of diabetes in the dental hospitals can help improve the patient's oral health and overall health status by helping patients avoid or reduce complications from diabetes.

Background: Colonoscopy is the preferred screening method for colorectal cancer (CRC). This study aimed to identify factors motivating a beneficial health behavior, that is, the decision to complete a colonoscopy. Methods: We surveyed 91 primarily urban minority health care workers who were ineligible for a large randomized controlled trial due to self-reported asymptomatic colonoscopy screening. Participants were asked an open-ended question about what made them get screened. Responses were classified as external or internal motivations. Results: The most commonly reported external motivation was a primary care physician's recommendation (n = 60, 65.9%). Other external motivations were familiarity with CRC or polyps through family or work (n = 16, 17.6%) and pressure from relatives or friends (n = 8, 8.8%). Seventeen respondents were deemed self-motivated; these individuals were more likely have income over $50K/year (P < 0.05) and to be US born (P = 0.05); they were more likely to mention being age-appropriate for screening (P < 0.05); knew more people who had colonoscopies (P < 0.001); they were less likely to believe that most of the age-appropriate population in New York City has been screened (P < 0.01) and less likely to be deterred from colonoscopy by work schedule (P < 0.001) or by having to take a powerful laxative (P < 0.001). Conclusions: A primary care physician's recommendation may be the most prevalent motivating factor in patients' decisions to receive a colonoscopy, but a subgroup seeks CRC screening on their own. Analysis of the motivations of individuals who have sought colonoscopy screening may offer useful insights into motivating those who have not.
