This study aimed at investigating the sex and age-related parasitic burden of Clarias gariepinus cultured in earthen ponds. Eighty–five (85) fish samples were selected randomly for analyses from three earthen ponds. Sexing was done by the observation of the urinogenital papillae. For parasitological analysis, skin and gill scrapes were taken for external parasites while the stomach and intestines were slit open, rinsed and observed for helminthic worms. Parasites identified included; Chilodonella sp. (0.3%), Ichthyophthirius sp. (41.1%), Trichodina sp. (55%), Icthyobodo sp., (1.0%) and Gyrodactylus sp. (2.4%). From the study 31 out of 56 males and 20 out of 27 females were infected with parasites. Prevalence of infection in males and females were 55.36% and 74.07% respectively. Mean intensity of parasites was also higher for females (150.75) than for males (62.68) Chi square analysis however, revealed no significant effect (p<0.05) of parasitism on gender. It was further observed that juvenile males and early adult females respectively, had more parasites with 55.3 and 92.4 parasite mean intensities. Among age groups, the mid juveniles (25-99g) (19%), late juveniles (100-299g) (65%) and early adults (300-500g) (14%) were most infected, although there was no significant effect (p<0.05). Sex-related prevalence could be based on hormonal changes and reproduction in females, and competitive search for mates by males. Age-related infection was predicated upon active feeding habits reported among fish of these ages It is therefore recommended that routine health checks be carried out for pond cultured fish. Furthermore, that older fish be sorted and kept together, as they would have stronger immunity than younger fish.

This investigation was designed to assess sex-role stereotyping across age groups. Participants ( N = 668) were girls and boys, students from Grades 3, 5, 8, and 10 at local public schools. All participants completed the Sport and Physical Activities Questionnaire on which were displayed pictures of 31 sport and physical activities. Participants were instructed to designate each activity as a boys' activity, a girls' activity, or a boys' and girls' activity. Chi-square analysis showed age-related differences in distribution of stereotyping of the activities. Over age groups there were more discrepancies between boys' and girls' ratings of activities as sex-specific. These findings suggest that sex-role stereotyping of sports and physical activities becomes more predominant across age groups.

Abstract We examined social class (measured by attendance in public or private schools), gender, and age-related variations in the expression of wishes and gratitude of 430 7- to 14-year-olds (181 male, 62.1% from public schools). Chi-square analysis indicated that students from private schools expressed significantly more social-oriented wishes and connective gratitude, whereas those from public schools expressed significantly more self-oriented wishes. Girls in the public schools expressed significantly more self-oriented wishes and verbal gratitude than did boys. Regression analysis (curve estimation) indicated that verbal gratitude, self- and social oriented wishes increased and concrete gratitude decreased significantly with age, but connective gratitude tended to increase. These findings support the idea that gratitude and wish types involve the development of cognitive aspects, such as taking others into account and thinking about the future, but it is also influenced by the social contexts in which children live, such as their social class.

The aims of this study were two-fold: (1) to inspect separately for the relative age and birthplace effects for players selected in the National Basketball Association (NBA) draft; (2) to explore the interaction among these factors and analyse this interaction in players' career performance. The database was obtained from the official records of the players (n = 1,738), who were selected during the annual editions of the NBA Draft from 1990 to 2019. The participants' date of birth was analyzed according to the month of birth and divided into four quartiles. The place of birth was compared to the distribution of the general population' places of birth based on different communities' sizes. Chi-square analysis were used to determine if the relative age and birthplace of the players drafted differed in any systematic way from official census population distributions. Cluster analysis and standardized residuals were calculated to analyse the interaction among the contextual factors and the players' career performance. The data revealed that early-born players (Q1 and Q2) were over-represented. Moreover, players born in smaller cities (&lt;100,000) were over-represented. The interaction analysis revealed that the players born in the bigger communities relate mainly with relatively younger players, and clusters that correspond to players born in smaller communities integrated the relatively older players. No differences were found in the players' career performance. Researchers, coaches and practitioners should be aware of the interaction between contextual factors to help nurture the development of sport talent regardless of age-related issues or communities' size.

Introduction: Sickle cell disease (SCD) is associated with recurrent complications and healthcare burden. Although SCD management guidelines differ based on age groups, little is known regarding actual utilization of preventative (hydroxyurea) and palliative therapies (opioid and nonopioid analgesics) to manage complications. This study assessed whether there were age-related differences in SCD index therapy type and SCD-related medication utilization.Design and patients: Texas Medicaid prescription claims from September 1, 2011 to August 31, 2016 were retrospectively analyzed for SCD patients aged 2-63 years who received one or more SCD-related medications (hydroxyurea, opioid, or nonopioid analgesics).Outcome measures: The primary outcomes were SCD index drug type and medication utilization: hydroxyurea adherence, and days’ supply of opioid, and nonopioid analgesics. Chi-square, analysis of variance, and Kruskal–Wallis tests were used.Results: Index therapy percentages for included patients (N = 2,339) were the following: opioids (45.7 percent), nonopioids (36.6 percent), dual therapy-opioids and nonopioids (11.2 percent), and hydroxyurea (6.5 percent), and they differed by age-groups (χ2 = 243.0, p 0.0001). Hydroxyurea as index therapy was higher among children (2-12:9.1 percent) compared to adults (26-40:3.7 percent; 41-63:2.9 percent). Opioids as index therapy were higher among adults (18-25:48.0 percent; 26-40:54.9 percent; 41-63:65.2 percent) compared to children (2-12:36.6 percent). Mean hydroxyurea adherence was higher (p 0.0001) for younger ages, and opioid days’ supply was higher for older ages.Conclusions: Texas Medicaid SCD patients had low hydroxyurea utilization and adherence across all age groups. Interventions to increase the use of hydroxyurea and newer preventative therapies could result in better management of SCDrelated complications and reduce the frequency of pain crises, which may reduce the need for opioid use.

419 Background: Renal cell cancer (RCC) incidence is relatively low in younger patients, encompassing 3-5% of all RCC tumors. These tumors tend to be due to hereditary syndromes and genetic mutations that predispose to cancer development. Patients with hereditary renal cancer (HRC) are at a higher risk of multiple tumors and bilateral disease. We hypothesize that there is a difference in histologic distribution in the younger patients and that the younger distribution contains more aggressive histologic subtypes. Methods: SEER 18-registries database was queried for all patients ≥20 years old that were surgically treated for renal cell carcinoma between the years 2001 and 2008. Patients with unknown race, grade, stage, or histology were excluded from the study. Histologies selected were clear cell, papillary, chromophobe, sarcomatoid, and collecting duct. Three cohorts were created with the ages 20-44, 45-64, and ≥65 year olds that contained 3,926, 19,661, and 16,323 patients respectively. Chi-square analysis was used to compare the histologic distributions between the cohorts. Results: There was no difference in the incidence of clear cell RCC between the three cohorts (p = 0.63). The histology distribution was not different in the 45-64 year olds compared to those ≥65 (p = 0.47). The non-clear cell histologies were different between the 3 age groups (p < 0.001). There were a larger percentage of patients in the younger patients that had chromophobe tumors compared to all non-clear cell histologies (p< 0.001). Conclusions: The difference in the non-clear cell histologic distribution between the groups is most likely due to genetic mutations predisposing these patients to chromophobe RCC. There has been limited data on HRCs, due in large part to its low incidence. Although the HRCs are known to have a most common histology, it is likely that this information is incomplete, as younger patients have undiagnosed genetic mutations that led to development of chromophobe tumors.

The worm infections can cause a decrease in livestock productivity, were in the form of a decrease in body weight, milk production, growth restriction, decrease immunity to disease, even death. Research on worm disease in Boer goats aims to determine the infection rate of Nematodiasis and Trematodiasis in goats with various age levels, young and adult age groups. This research method is survey with sampling technique is sampling by the judgment. The data analysis of the research was prevalence study and Chi-Square analysis (X2). The examination of worm eggs in feces on the research used centrifuge method. The results of examination on 30 samples of Boer goats showed that 93.33% of Boer goats were infected by Nematodes and 13.33% of Boer goats were infected by Trematoda. Infection rates of Nematodes and Trematoda were not showed any significant differences between the two groups. The low level of Trematodiasis in Boer goats indicates that Boer goats in Banyumas district are resistant to Trematoda worm infections. Keywords: Boer Goats, Centrifuge Method, Chi-Square Analysis, Infection Rate, Worm Infection

For the indigenous minorities of the far North, venison is the main environmentally safe food product. The study was aimed at determining the chemical composition, the weight, and the content of macro- and microelements in the subproducts of domesticated reindeer in Yakutia for further production of composite and functional food products, following the current ecological situation in the region. The subproducts of domesticated reindeer of the Chukchi and Evenki breeds are distinguished by the weight of the liver, the kidneys, the stomach, and the intestines; with that, the weight of subproducts in males was higher than in females. The comparatively high relative weight of internal organs in the reindeer of the Chukchi breed is associated with the better development of viability in the adverse conditions of the tundra habitat. Differences are observed within the content of nutrients in the subproducts in various age groups (females, males, and calves); this difference in the content of protein and fat is associated with the age-related feeding habits and the accumulation of nutrients in the organism of the deer. For instance, calves in this period feed on mother's milk; besides, the growing organism of a calf accumulates additional nutrients. The heart and the spleen of calves contain more macroelements (Ca, P, Mg, K, Na, and Cl) than those of male and female deer, while the kidneys, on the contrary, contain less macroelements. The content of microelements (Se, Fe, Mn, Cu, Zn, and F) in the heart and the spleen of calves is higher, and in the liver and the kidneys, it is lower.

Plasmodium falciparum is the most virulent and prevalent malaria parasite in Nigeria .This study aimed to determine the prevalence of malaria infection among patients at General Hospitals in Benue State. A total of 1200 patients were examined in this study.  Blood samples were collected by finger prick onto clean slides and into the round sample well of PfRDTs. Thick and thin blood films were prepared for microscopic examination. The overall prevalence of malaria infection was 34.8%. A questionnaire was used to determine some demographic factors. Prevalence of malaria in relation to residence, rural area recorded higher prevalence of 42.2% than urban area with prevalence of 23.8%. Chi square analysis showed a significant difference (p < 0.05) in prevalence in relation to residence. The Prevalence of malaria in relation to age groups, age between 6-10 and 7-15 recorded higher infection rate of 54.5% and 51.5% respectively. While, age group >46 recorded  17.5%. The female patients 36.2% were more infected than the males 33.1%.Patients that had informal education recorded higher prevalence rate of 89.2% and those that are farmers had 57.9%. Chi square analysis however showed that the difference was significant (p < 0.05). A significant difference  (P<0.05) was observed between patients that  used insecticide spray alone as malaria preventive methods (70.1%) compared to patients that used combined methods of prevention (17.2%). Malaria still remains prevalent among patients in Benue State, Nigeria.

The objective of our study was to survey the accumulated 2-methylisoborneol (MIB) and geosmin (GSM) in fillets of five important farmed fish species in Hungarian aquaculture in relation to MIB and GSM concentrations in water and sediment in the aquatic systems where they were raised: (the planktivorous silver carp (Hypophthalmichthys molitrix), the herbivorous grass carp (Ctenopharyngodon idella), the bottom-feeding omnivorous common carp (Cyprinus carpio), the omnivorous tilapia (Oreochromis niloticus) and the carnivorous African catfish (Clarias gariepinus)). Water, sediment and fish samples were collected from different experimental aquatic systems which included a combined aquaculture–algae (CAA) system, effluent-fed fishponds, a pond recycling system and a traditional fishpond. MIB and GSM contents were extracted with distillation-headspace solid-phase – microextraction (SPME) and extracts analysed by GC-MS. Results showed that off-flavour contents in fish fillets were related to the feeding habits of the studied fish species. Higher GSM concentrations were found in the fillet of bottom-feeding common carp than in the silver carp or African catfish in all studied aquatic systems. Usually, low GSM concentrations were detected in the water of fishponds but sometimes the levels of this odour compound in carp fillet were well above the limits of human detection. This suggests that the off-flavour tainting of common carp may originate from the sediment or benthic algal/actinomycete sources. Negligible MIB levels were found in all samples in all of the studied aquatic systems.
