It is not yet clear how the enjoyment of playing a sport is related to the degree of involvement an athlete feels in a game. This issue was examined in two field studies and one laboratory experiment focusing on how men and women experience competition on mixed-sex and single-sex sports teams, with a greater emphasis on the experience of women in these situations. The results showed that while the mean enjoyment levels for women in mixed-sex and single-sex games were not different, individual women usually display a preference for either mixed-sex or single-sex teams. The results also revealed that women felt more involved on single-sex teams and that both men and women passed to men more often in mixed-sex games. Future studies should look at possible differences between men and women in the sources of the rewards derived from competition.

Commit Suicide

The abuse of some pesticides especially to suicide is one of the current problems of pesticides. Aluminum phosphide induced poisoning usually happens to suicide and sometimes it is due to accidental occupational exposure and in a few cases it has some criminal intensions. This study is conducted to evaluate patients poisoned with aluminum phosphide. In the present study the medical records of cases of poisoning with rice tablets (aluminum phosphide) hospitalized in Ahvaz Razi hospital is studied. Accordingly, a checklist is prepared that included demographic information of patients (age, gender) and information on patient records (information on poisoning) are completed using the patients’ medical records. The analysis of data is done by SPSS V22. 18 patients poisoned with rice tablet (aluminum phosphide) are studied. Results of the study show that 11 patients are male and seven are female. The mean patient age is 27.06 ±8.04 years that is 28 ±9 and 25 ±6.02 in men and women respectively. Statistical tests show no statistically significant difference in mean age in both genders (P> 0.05). Among patients, 11 subjects took aluminum phosphide to attempt suicide and 3 cases took it unintentionally and of course the reason is not mentioned in four cases. Among the patients who tried to commit suicide by taking aluminum phosphide, 6 cases are male and 5 cases are female that no statistically significant difference is observed between the genders in this respect (P> 0.05). In addition to the study of the complications caused by this poisoning and its mortality, it is recommended to responsible authorities to provide the necessary educations and treatments to prevent this type of poisoning.

The Relationship

BACKGROUND: Obstructive sleep apnea (OSA) has been linked to vestibular dysfunction, but no prior studies have investigated the relationship between Persistent Postural Perceptual Dizziness (PPPD), a common cause of chronic dizziness, and OSA. OBJECTIVE AND METHODS: We determined the frequency of OSA in an uncontrolled group of PPPD patients from a tertiary dizziness clinic based on polysomnogram (PSG). We then assessed the sensitivity and specificity of common OSA questionnaires in this population. RESULTS: Twenty-five patients with PPPD underwent PSG (mean age 47, 60% female, mean BMI 29.5). A majority, or 56%, of patients were diagnosed with OSA, and in most, the OSA was severe. OSA patients were older (56 years versus 40 years, p = 0.0006) and had higher BMI (32 versus 26, p = 0.0078), but there was no clear gender bias (56% versus 64% female, p = 1.00). The mean sensitivity and specificity of the STOP BANG questionnaire for detecting OSA was 86% and 55%, respectively. Sensitivity and specificity of the Berlin Questionnaire was 79% and 45%, respectively. CONCLUSIONS: The prevalence of OSA was much higher in our small PPPD group than in the general population. Screening questionnaires appear to demonstrate good sensitivity to detect PPPD patients at risk of OSA in this small study. Future studies should confirm these findings and determine whether treatment of OSA improves symptoms in PPPD.

Circadian Patterns

The documentation of diurnal patterns in body temperature in lions could be important because disruption of circadian patterns can be a useful measure of distress. This study quantified changes in body temperature of seven African lions (Panthera leo) at 5 min intervals during cold conditions from noon until the ingested body temperature loggers were expelled the next day. Thirteen loggers were fed to 11 lions during their daily noon feeding, while ambient temperatures were also recorded using six data loggers. The lions had continuous access to their dens and exercise pens during the day but were restricted to their heavily bedded dens that also contained a heat lamp from 23:00 until 08:00 the next day. Body temperatures averaged 37.95 ± 0.42 °C at 15:50, and 36.81 ± 0.17 °C at 06:50 the next day, 30 min before the first loggers passed from a lion, and were significantly different (t-test, t = 8.09, df = 6, p < 0.0003). The mean duration for the time of passage was 22 ± 2.69 (h ± SD), so future studies using the noninvasive feeding of temperature loggers need to consider that time frame.

Abstract Objectives This study aimed to investigate sex differences in the medical utilization for ischemic heart disease (IHD) among newly diagnosed hypertensive patients using a cohort data of South Korea. Methods We analyzed the National Sample Cohort version 2.0 of the National Health Insurance Service. Newly diagnosed hypertensive patients aged 40–84 were extracted from the baseline population, who received health examinations during 2003–2006 without pre-existing type 2 diabetes or circulatory diseases. Propensity score was applied to match men to women with the same ratio of body mass index (BMI) and fasting blood glucose (FBG) among the patients. Men and women (each 10, 110) were selected for analyses and followed until the end of 2015. Person-year was defined as the period from the diagnosis of hypertension to the incidence of IHD. Associations between IHD and the medical care utilization such as the mean of medical care visit, the mean medical cost, and the type and the location of medical care providers were investigated using Cox proportional hazard model. Hazard ratios (HR) of IHD according to medical care utilization were adjusted for age, income, BMI, FBG, smoking, and alcohol consumption. Results Incidence rates (per 1000 person-years) of IHD were 43.1 in men and 43.0 in women. The mean follow-up period was 5.2 person-years. The HRs of IHD were significantly higher in the subjects with a high mean medical cost (T3) (men, HR = 1.39, 95% CI 1.25–1.54; women, HR = 1.33, 95% CI 1.20–1.48) than in those with a low mean medical cost (T1). However, the subjects visiting medical care providers more (T3) had lower HRs than those visiting less (T1) (men, HR = 0.80, 95% CI 0.72–0.89; women, HR = 0.79, 95% CI 0.71–0.88). Conclusions Hypertensive patients in Korea showed an increased risk of IHD when they paid medical cost more and visited medical care less per person-year in both men and women.

Ice Multiplication

Abstract This paper addresses the problem of the large discrepancies between ice crystal concentrations in clouds and the number of ice nuclei in nearby clear air reported in published papers. Such discrepancies cannot always be explained, even by taking into account both primary and secondary ice formation processes. A laboratory experiment was performed in a cylindrical column placed in a cold room at atmospheric pressure and temperature in the −12° to −14°C range. Supercooled droplets were nucleated in the column, in the absence of aerosol ice nuclei, by injecting ice crystals generated outside in a small syringe. A rapid increase in the ice crystal concentration was observed in the absence of any known ice multiplication. The ratio between the mean number of ice crystals in the column, after complete droplet vaporization, and the number of ice crystals introduced in the column was about 10:1. The presence of small ice crystals (introduced at the top of the column) in the unstable system (supercooled droplets) appears to trigger the transformation in the whole supercooled liquid cloud. A possible explanation could be that the rapidly evaporating droplets cool sufficiently to determine a homogeneous nucleation.

Abstract Sudden stratospheric warmings (SSWs) are characterized by a pronounced increase of the stratospheric polar temperature during the winter season. Different definitions have been used in the literature to diagnose the occurrence of SSWs, yielding discrepancies in the detected events. The aim of this paper is to compare the SSW climatologies obtained by different methods using reanalysis data. The occurrences of Northern Hemisphere SSWs during the extended-winter season and the 1958–2014 period have been identified for a suite of eight representative definitions and three different reanalyses. Overall, and despite the differences in the number and exact dates of occurrence of SSWs, the main climatological signatures of SSWs are not sensitive to the considered reanalysis. The mean frequency of SSWs is 6.7 events decade−1, but it ranges from 4 to 10 events, depending on the method. The seasonal cycle of events is statistically indistinguishable across definitions, with a common peak in January. However, the multidecadal variability is method dependent, with only two definitions displaying minimum frequencies in the 1990s. An analysis of the mean signatures of SSWs in the stratosphere revealed negligible differences among methods compared to the large case-to-case variability within a given definition. The stronger and more coherent tropospheric signals before and after SSWs are associated with major events, which are detected by most methods. The tropospheric signals of minor SSWs are less robust, representing the largest source of discrepancy across definitions. Therefore, to obtain robust results, future studies on stratosphere–troposphere coupling should aim to minimize the detection of minor warmings.

Purpose: To corroborate the validity of a computerized methodology for evaluating carotid lesions at risk for stroke based on plaque echogenicity. Methods: The records of 96 carotid endarterectomy patients (59 men; median age 69.5 years, range 52 to 83) with stenoses > 50% were studied retrospectively. Forty-one patients (43%) had been symptomatic preoperatively. All patients had undergone computed tomography (CT) to detect infarction in the carotid territory and a duplex scan to measure carotid stenosis. Plaque echogenicity was analyzed by computer, expressing the echodensity in terms of the gray scale median (GSM). The incidence of CT-documented cerebral infarction was analyzed in relation to symptomatology, percent stenosis, and echodensity. Results: Symptoms correlated well with CT evidence of brain infarction: 32% of symptomatic patients had a positive CT scan versus 16% for asymptomatic plaques (p = 0.076). The mean GSM value was 56 ± 14 for plaques associated with negative CT scans and 38 ± 13 for plaques from patients with positive scans (p < 0.0001). However, there was no difference in the GSM value between plaques with > or < 70% stenosis. Furthermore, the incidence of CT infarction was 40% in the cerebral territory of carotid plaques with a GSM value < 50 and only 9% in those with a GSM > 50 (p < 0.001). Conclusions: Computerized analysis of plaque echogenicity appears to provide clinically useful data that correlates with the incidence of cerebral infarction and symptoms. This method of analyzing plaque echolucency could be used as a screening tool for carotid stent studies to identify high-risk lesions better suited to conventional surgical treatment.

This research examined pro-environmental behaviour between adults and youths in Nginda ward, Embu north sub County. The research relied on two theories, theory of planned action and theory of pro-social behaviour. The research followed a descriptive design. Data were collected using questionnaires with closed and open-ended questions. The researcher administered questionnaires in person, and filled the entire questionnaire according to the participant’s responses. In total 245 participants comprising, 124 adults (comprising men and women), 121 form three students drawn from Muvandory, Rugumu and St. Alphose day Secondary Schools, and 58 standard seven pupils from Rugumu, Muvandory and ST. Francis primary schools were involved in the study. Descriptive statistics were used to summarise data and compare responses between groups. Differences in pro-environmental behaviour between adults and school children were examined to determine if the differences were statistically significant. A total of fourteen environmental problems were mentioned by participants to be prevalent in Nginda ward. The top three environmental problems mostly mentioned by participants included deforestation, water pollution and air pollution. The findings of this research can guide interventions by government and donor agencies seeking to mobilise and engage participation by both students and adults to combat environmental problems in Nginda ward. Future studies are needed to find out whether the scale will produce similar result in other group in this community which include business community, factory workers and eatery owners
