Question Formats

This paper compares protest rates and willingness to pay (WTP) using a payment card versus single and double bounded voter referendum contingent valuation question formats. Using a chi-square test, the payment card had a significantly higher protest rate (6.7 per cent) than the voter referendum question format (2.2 per cent). The median WTP of the single bounded and double bounded referendum format exceeds the payment card by a factor of nine and seven, respectively. The median WTP from the referendum formats represent about 8 per cent of income, while the payment card results represents about 1 per cent of income. These large differences in WTP between question formats are double what have been found in past studies. We believe this result may be due to excessive yea saying at high bid amounts in the dichotomous choice question formats. This behavior may arise in our case study in rural China because citizens have not had a long history of open elections or voting on tax referenda.

This study aimed at documenting whether dromedary camels have a preference for shade and how their behavior would change depending on the presence of shade and variable space allowance. A total of 421 animals kept in 76 pens (66 with shelter (Group 1), and 10 without shelter (Group 2)) at the camel market in Doha (Qatar) were recorded for 1 min around 11:00 a.m. when the temperature was above 40 °C. The number of animals in the sun and shade and their behaviors were analyzed using an ad libitum sampling method and an ad hoc ethogram. The results of a chi-square test indicated that camels in Group 1 had a clear preference for shade (p < 0.001). The majority of Group 1 camels were indeed observed in the shade (312/421; 74.11%). These camels spent more time in recumbency and ruminating, while standing, walking, and self-grooming were more commonly expressed by the camels in the sun (p < 0.001). Moreover, locomotory stereotypic behaviors (i.e., pacing) increased as space allowance decreased (p = 0.002). Based on the findings of this pilot study, camels demonstrated a preference for shade; shade seemed to promote positive welfare, while overcrowding seemed to trigger stereotypy and poor welfare. Overall, our preliminary results are novel and provide evidence that shaded areas are of paramount importance for camel welfare. Further research, involving designed studies at multiple locations is needed to confirm these results.

ABSTRACT Aim To determine microbial prevalence in the mucous membrane and prosthesis of denture wearers with and without denture stomatitis and to study its relationship with potential clinical cofactors. Materials and methods Saliva was collected from 200 patients (100 female and 100 male) wearing dental prosthesis for measurement of pH. Oral samples of the mucous membrane and of dentures were taken with sterile swab for microbiological analysis. Medical and dietary history of the subjects was recorded. Chi-square test and analysis of varience were used for statistical analysis. Results Diabetes, hypertension and high carbohydrate ingestion was observed in majority of patients. The pH average in saliva was of 5.1. The presence of C. albicans, S. aureus and S. mutans in the mucous membrane was of 55.4, 56.4 and 63.6% respectively. C. albicans was isolated in 69.7% from the prosthesis, whereas S. aureus and S. mutans were isolated in 45.3%. The isolation of C.albicans was more frequent in patients with deture stomatitis. Conclusion C. albicans, S. aureus and S. mutans frequently colonize the oral mucous of denture wearers. This is more frequently observed in patients with denture stomatitis. Clinical significance Denture stomatitis is associated to Candida albicans, different bacteria and other cofactors, such as salivary pH, carbohydrate ingestion, systemic illnesses and medication.

Hypertension is one of the number one causes of death and disability in the world. Hypertension contributes nearly 9.4 million deaths from cardiovascular disease each year. Hypertension can cause undesirable effects, it needs good handling, one of them is by doing a hypertension diet. To carry out a hypertension diet requires knowledge, lack of knowledge can increase risk factors for hypertension. This study aims to determine the relationship of the level of knowledge about hypertension diet to the incidence of hypertension in the elderly at the Baloi Permai Public Health Center Batam City. This research method is an analytic observational with a cross-sectional approach conducted at the Baloi Permai Public Health Center Batam City 2018. Sampling technique is a total sampling with a sample of 64 people in 2018 determined by inclusion and exclusion criteria. The results of the study were analyzed with frequency distribution and then tested with the Chi-square test. Based on the results of this study indicate that of the 64 respondents found elderly who have a good level of knowledge are 41 people (64.1%), 48 people (75.0%) have an age range between 60-70 years. 27 people (42.2%) elderly have the last high school education and 40 people (62.5%) have jobs as entrepreneurs. Elderly people who have normal blood pressure are 40 people (62.5%), and those affected by hypertension are 24 people (37.5%). The elderly who have a family history of hypertension is 21 people (32.8%) and those who do not have a history of hypertension are 43 people (67.2%). Chi-Square Test analysis results show the significance value p = 0.009. This number is significant because the p-value is smaller than the significance level (α) ≤ 5% (0.05), so H0 is rejected and Ha is accepted. Therefore it can be concluded that there is a significant relationship about the level of knowledge about the hypertension diet to the incidence of hypertension in the elderly. From the results of this study it was concluded that there was a relationship between the level of knowledge about the hypertension diet and the incidence of hypertension in the elderly at the Baloi Permai Public Health Center Batam City in 2016.

Leptospirosis is associated with occupations which exposed workers to contaminated environments. The risk of leptospirosis exposure in the market as a gathering place for many people needs to be assessed, to obtain the basis for decision making to anticipate leptospirosis transmission. This study aimed to determine the relationship between market environmental conditions including market sanitation conditions, the level of rat density and the presence of leptospira-positive rats  toward the history of leptospirosis exposure among market workers (traders and janitors). A cross sectional study conducted in 35 markets in Banjarnegara and 175 market workers randomly selected. Blood samples analysed using ELISA against 40 Kda pathogenic Leptospira protein. Rat trapping  conducted in each market for two days with 100 traps. The caught mice examined with Polymerase Chain Reaction (PCR) to detect the presence of Leptospira bacteria in their kidneys. Leptospirosis exposure was spread in 17 markets in Banjarnegara. The PCR examination showed that the pathogenic Leptospira infected rats were spread in four markets in Banjarnegara. Chi square test showed that the hygene condition in market area was significantly associated with the leptospirosis exposure. Markets workers (traders and janitors) were at risk for leptospirosis proved by high seroprevalence of leptospirosis in this study.

Stunting is a children growth problem that occurs a result of chronic malnutrition in the first 1000 days of life. The indicator of stunting is using the height measurement according to age HFA (Height for Age) under -2 SD based on the WHO growth standard curve according to sex. The impacts of stunting are the occurrence of growth disorders, barriers to development and the risk of metabolic disorders in adulthood. One of the risk factors for stunting is history of quality and quantity Antenatal Care (ANC). This study aimed to determine the relationship between quality and quantity history of ANC visits and stunting in toddlers aged 24-59 years in Pujon District Malang Regency. The method used in this research was observational analytic by using cross-sectional design. The population of this study was all mothers who have children aged 24-59 months that were conducted in January 2020. Ninety eight respondents taken by purposive sampling as the sample of the research. The data was obtained by filling out questionnaires and KIA books, then analyzed with chi-square test (α = 0.05). The results showed that there was a significant relationship in quality (p-value = 0.004) and quantity (p-value = 0.003) toward stunting.

Background: Uterine synechiae refers to a total or partial union of the inner walls of the uterus resulting from endometrial trauma. It is a cause of reproductive failure. Until now, synechia was not optimally treated and has remained understudied in Cameroon. Objective of present study was to Evaluate the diagnostic, therapeutic and prognostic aspects of uterine synechiae treated by hysteroscopy.Methods: We conducted a descriptive cross-sectional study with an analytical component from January 1st 2015 to July 31st 2017 at Yaounde. All patients diagnosed with uterine synechiae and treated with hysteroscopy were our sample. Sampling was consecutive. The chi-square test was used for the comparison of qualitative variables and Fisher's test for ANOVA variance analysis. The comparison of the averages was made by the Student's test. P-value less than 0.05 was considered as statistically significant.Results: Hysteroscopies were indicated for uterine synechiae in 14.50%. Nulliparous were 56.67%. A history of curettage/aspiration was present in 66.66%. All of the patients had a form of infertility and 83.33% had menstrual disorders. Hysterosalpingography showed a better sensitivity (88%). After hysteroscopic treatment, 63.30% had a complete anatomical restitution. There is a significant correlation between the stage of severity of synechia and anatomical restitution (p=0.008; Spearman correlation coefficient=-0.477).Conclusions: Uterine synechiae represent one-sixth of all indications for hysteroscopy and present clinically as menstrual disorder associated with infertility. A past history of uterine curettage is common. Hysterosalpingography has a better preoperative diagnostic sensitivity. Hysteroscopy allows optimal treatment.

Abstract Background: The incidence of tuberculosis in HIV patients (TB-HIV) w as estimated at 126 per 100,000 in the world. The number of HIV infected patients in Indonesia around 190,000 to 400,00 0 and the prevalence of TB-HIV is 5%. Data TB-HIV still increase s and they are un aware of that until a late stage. Understanding the risk factors of people with TB-HIV co-infection is important to know. This study aims to know the predictors of TB-HIV patients in the clinic voluntary counseling and testing (VCT) in Medan city. Methods: This is a case-control study. The case is TB-HIV patients (aged > 20 years) seen at clinic VCT Medan in 2016. Control is HIV patients without TB (aged > 20 years) seen in the same clinic VCT. The number of cases was 120 and the number of control 120. Data were collected from the medical record. Data were analyzed using the chi-square test in SPSS software. Results: The t otal was 240 patients. The majority were in the age group 31-40 years old (52.9%), male (75.8%), married (71.7%), had tertiary education (85.4%), had employment (89.2%) . Significant factors were CD4 < 500 cells/ml (OR 3.92; 95% CI 2.13-7.22), BMI < 18.5 kg/m2 (OR 5.79; 95% CI 3.25-10.21), had history of TB family (OR 7.9; 95% CI 3.67-18.18), adherence ARV (OR 1.35; 95% CI 1.02-1.79). Conclusions: The predictors of incidence TB-HIV co-infection was low CD4, low BMI, and had a family history of TB. Pay the attention for the nutritional status of TB-HIV patients and provide appropriate nutritional intake needs and adherence ARV.
