RESUMO

Anadromous river herring have declined in many parts of their range, leading to fisheries management efforts to help repopulate this species by improving connectivity of rivers and restoring populations by fish transfers. With data lacking on parasites in these species, this study sought to better understand myxozoans across various life stages and habitats in river herring populations in New Jersey, USA. We compared fish from riverine habitats during early-life growth and adults returning to spawn, marine-phase fish, and landlocked Alewife populations. Three myxozoan species were identified in young-of-the-year (YOY) anadromous river herring, including Kudoa clupeidae in the skeletal musculature, Myxobolus mauriensis in the rib cartilage, and an uncharacterized coelozoic myxozoan within the lumen of mesonephric tubules. In YOY river herring, Blueback Herring were 2 times more likely to be infected by K. clupeidae than Alewife (p = 0.019) and in the Maurice River, fish were 4 times more likely to be infected with M. mauriensis than fish from Great Egg Harbor River (p = 0.000) and 11 times more likely than the Delaware River (p = 0.001). Spawning adult river herring were infected with a previously undescribed myxozoan parasite infecting the kidney. Sequencing the 18S rDNA indicated this species is closely related to Ortholinea species. Myxobolus mauriensis and the Ortholinea-like species were absent from marine-phase river herring indicating that infections were linked to river environments occurring during early-life growth and spawning, respectively. No myxozoans were present in landlocked Alewife, showing that similar infections occurring in rivers were absent in lake environments in the region.

RESUMO

Wild bluegill, Lepomis macrochirus Rafinesque, succumb to seasonal mortality in the early spring during cool water temperatures, shown previously to be related to bacteraemia caused by a psychrotrophic bacterium, Pseudomonas mandelii. In the study herein, intestinal coccidiosis in wild bluegill had seasonal prevalence causing heavy intestinal infections and sloughing of intestinal epithelium occurring in late winter/early spring. Infections were predominantly related to two different species, Goussia washuti n. sp., an epicellular coccidium, and a coccidium closely resembling Goussia desseri Molnár 1996, previously only described in percid fish in Europe. In 2019, co-infections of bacteraemia and intestinal coccidiosis occurred in bluegills. Evaluating coccidium infection intensity by fresh parasite examination and histology, an association was observed in which fish with moderate-to-heavy intestinal coccidiosis were 8-12 times more likely to have bacteraemia compared to fish with no or light coccidiosis. The association of these co-infections suggests that intestinal coccidiosis could contribute to seasonal bacterial epizootics of wild bluegill.

RESUMO

OBJECTIVE: The purpose of this case study is to describe two successful HOME Plus participants and highlight how an intervention with individual and group components can help families make lifestyle changes that result in improvements in child weight status. DESIGN: One hundred and sixty families participated in the HOME Plus study, and were randomized to either a control or intervention group. SAMPLE: Two successful HOME Plus participants were chosen because of their healthful changes in weight status and behavior and high engagement in the program. MEASUREMENTS: Data were collected at baseline and postintervention, 1 year later. Data included height, weight, home food inventory, dietary recalls, and psychosocial surveys. INTERVENTION: Families in the intervention group participated in cooking and nutrition education sessions, goal-setting activities, and motivational interviewing telephone calls to promote behavioral goals associated with meal planning, family meal frequency, and healthfulness of meals and snacks. RESULTS: Analysis of the families' behaviors showed that Oliver (fictitious name) experienced changes in nutritional knowledge and cooking skill development while Sophia's (fictitious name) changes were associated with healthful food availability and increased family meal frequency. CONCLUSION: These cases show that offering a multicomponent, family-focused program allows participants to select behavior strategies to fit their unique family needs.

RESUMO

For youth and parents, frequent family meals have been consistently associated with positive dietary outcomes but less consistently associated with lower body mass index (BMI). Researchers have speculated dinnertime context (dinnertime routines, parent dinnertime media use) may interact with family meal frequency to impact associations with BMI. The present study evaluates the associations and interactions between dinnertime context measures and family dinner frequency with parent and child BMI. This cross-sectional study uses baseline data from the Healthy Home Offerings via the Mealtime Environment (HOME) Plus randomized control trial that aimed to prevent childhood obesity. Participants (160 parent-child dyads) completed psychosocial surveys and were measured for height and weight. General linear models tested associations and interactions between dinnertime context measures and family dinner frequency with parent and child BMI, adjusted for race and economic assistance. Lower parent dinnertime media use and higher dinnertime routines were significantly associated with lower child BMI z scores but not parent BMI scores. Interaction-moderation findings suggest higher family dinner frequency amplifies the healthful impact of the dinnertime context on child BMI z scores. Additionally, findings emphasize that promoting frequent family meals along with consistent routines and reduction in parent dinnertime media use may be important for the prevention of childhood obesity.

RESUMO

OBJECTIVE: To investigate reasons why parents purchase prepackaged, processed meals and associations with parental cooking self-efficacy, meal-planning ability, and home food availability. METHODS: This secondary data analysis uses Healthy Home Offerings via the Mealtime Environment Plus study data from parents of children aged 8-12 years (n = 160). Associations between reasons why parents purchase prepackaged, processed meals and the outcomes were assessed with chi-square, Fisher exact, and t tests. RESULTS: The most frequently endorsed reasons for purchasing prepackaged, processed meals included lack of time (57%) and family preferences (49%). Five of 6 reasons were associated with lower parental cooking self-efficacy and meal-planning ability. Some reasons were associated with less-healthful home food environments; few reasons varied by socio-demographic characteristics. CONCLUSIONS AND IMPLICATIONS: Because lower cooking self-efficacy and meal-planning ability are associated with most reasons reported for purchasing prepackaged, processed meals, strategies to increase these attributes for parents of all backgrounds may reduce reliance on prepackaged processed meals for family mealtimes.

RESUMO

Surveillance for pathogens of Atlantic herring, including viral hemorrhagic septicemia virus (VHSV), Ichthyophonus hoferi, and hepatic and intestinal coccidians, was conducted from 2012 to 2016 in the NW Atlantic Ocean, New Jersey, USA. Neither VHSV nor I. hoferi was detected in any sample. Goussia clupearum was found in the livers of 40 to 78% of adult herring in varying parasite loads; however, associated pathological changes were negligible. Phylogenetic analysis based on small subunit 18S rRNA gene sequences placed G. clupearum most closely with other extraintestinal liver coccidia from the genus Calyptospora, though the G. clupearum isolates had a unique nucleotide insertion between 604 and 729 bp that did not occur in any other coccidian species. G. clupearum oocysts from Atlantic and Pacific herring were morphologically similar, though differences occurred in oocyst dimensions. Comparison of G. clupearum genetic sequences from Atlantic and Pacific herring revealed 4 nucleotide substitutions and 2 gaps in a 1749 bp region, indicating some divergence in the geographically separate populations. Pacific G. clupearum oocysts were not directly infective, suggesting that a heteroxenous life cycle is likely. Intestinal coccidiosis was described for the first time from juvenile and adult Atlantic herring. A novel intestinal coccidian species was detected based on morphological characteristics of exogenously sporulated oocysts. A unique feature in these oocysts was the presence of 3 long (15.1 ± 5.1 µm, mean ±SD) spiny projections on both ends of the oocyst. The novel morphology of this coccidian led us to tentatively name this parasite G. echinata n. sp.

RESUMO

BACKGROUND: Family meal frequency has been consistently and significantly associated with positive youth dietary and psychosocial outcomes, but less consistently associated with weight outcomes. Family meal frequency measurement has varied widely and it is unclear how this variation might impact relationships with youth weight, dietary, and psychosocial outcomes. OBJECTIVE: This study assesses how five parent/caregiver-reported and four child-reported family dinner frequency measures correlate with each other and are associated with health-related outcomes. DESIGN/PARTICIPANTS: This secondary, cross-sectional analysis uses baseline, parent/caregiver (n=160) and 8- to 12-year-old child (n=160) data from the Healthy Home Offerings via the Mealtime Environment (HOME) Plus trial (collected 2011 to 2012). Data were obtained from objective measurements, dietary recall interviews, and psychosocial surveys. OUTCOME MEASURES: Outcomes included child body mass index z scores (BMIz); fruit, vegetable, and sugar-sweetened beverage intake; dietary quality (Healthy Eating Index-2010); family connectedness; and meal conversations. STATISTICAL ANALYSES PERFORMED: Pearson correlations and general linear models were used to assess associations between family dinner frequency measures and outcomes. RESULTS: All family dinner frequency measures had comparable means and were correlated within and across parent/caregiver and child reporters (r=0.17 to 0.94; P<0.01). In unadjusted analyses, 78% of family dinner frequency measures were significantly associated with BMIz and 100% were significantly associated with fruit and vegetable intake and Healthy Eating Index-2010. In adjusted models, most significant associations with dietary and psychosocial outcomes remained, but associations with child BMIz remained significant only for parent/caregiver- (ß±standard error=-.07±.03; P<0.05) and child-reported (ß±standard error=-.06±.02; P<0.01) family dinner frequency measures asking about "sitting and eating" dinner. CONCLUSIONS: Despite phrasing variations in family dinner frequency measures (eg, which family members were present and how meals were occurring), few differences were found in associations with dietary and psychosocial outcomes, but differences were apparent for child BMIz, which suggests that phrasing of family dinner frequency measures can influence associations found with weight outcomes.

RESUMO

Anadromous alewives, Alosa pseudoharengus, have experienced significant population level declines caused by factors including habitat destruction. Alewives occur in two different life histories, anadromous and landlocked forms. The landlocked alewife evolved from ancestral anadromous populations, resulting in an exclusively freshwater and phenotypically unique form. The occurrence of parasites in a host is linked to the environment, making alewives an ideal model to compare parasitology within a single species with contrasting life histories. Currently, little information exists on the presence and impacts of parasites in these fish populations; the present study sets out to better understand coccidiosis in the threatened anadromous populations and to understand how coccidian parasites compare in both life history forms. The intestinal coccidian, Goussia ameliae n. sp., was described infecting the pyloric cecum of 76% and 86% of young-of-the-year and adult anadromous alewives, respectively, from the Maurice River, New Jersey, USA. The coccidian was found in landlocked alewife populations with a prevalence of 92% and 34% in YOY and adult fish, respectively. An analysis of the small subunit 18S ribosomal RNA gene of G. ameliae from both life history forms demonstrated that the coccidian had 100% sequence identity, confirming the same parasite species in both forms. Though genetic analysis demonstrated G. ameliae to be identical, some differences were observed in sporulation and morphology of the parasite within the two populations. The sporocysts in anadromous populations were shorter and wider, and sporulation timing differed from that of landlocked fish. These differences may either be attributed to differences in the host type or to the sporulation environment. Lastly, alewives from landlocked populations were frequently co-infected with a second coccidian species in the posterior intestine, which occurred at a lower prevalence. This species, G. alosii n. sp., was described based on morphological characters of the sporulated oocysts in fresh parasitological preparations.

RESUMO

BACKGROUND: Weight-related problems are prevalent in adolescent girls. PURPOSE: To evaluate New Moves, a school-based program aimed at preventing weight-related problems in adolescent girls. DESIGN: School-based group-randomized controlled design. SETTING/PARTICIPANTS: 356 girls (mean age=15.8±1.2 years) from six intervention and six control high schools. More than 75% of the girls were racial/ethnic minorities and 46% were overweight or obese. Data were collected in 2007-2009 and analyzed in 2009-2010. INTERVENTION: An all-girls physical education class, supplemented with nutrition and self-empowerment components, individual sessions using motivational interviewing, lunch meetings, and parent outreach. MAIN OUTCOME MEASURES: Percentage body fat, BMI, physical activity, sedentary activity, dietary intake, eating patterns, unhealthy weight control behaviors, and body/self-image. RESULTS: New Moves did not lead to significant changes in the girls' percentage body fat or BMI but improvements were seen for sedentary activity, eating patterns, unhealthy weight control behaviors, and body/self-image. For example, in comparison to control girls, at 9-month follow-up, intervention girls decreased their sedentary behaviors by approximately one 30-minute block a day (p=0.050); girls increased their portion control behaviors (p=0.014); the percentage of girls using unhealthy weight control behaviors decreased by 13.7% (p=0.021); and improvements were seen in body image (p=0.045) and self-worth (p=0.031). Additionally, intervention girls reported more support by friends, teachers, and families for healthy eating and physical activity. CONCLUSIONS: New Moves provides a model for addressing the broad spectrum of weight-related problems among adolescent girls. Further work is needed to enhance the effectiveness of interventions to improve weight status of youth.
