This study investigated the association between dietary flavonoid intake and hearing impairment in older adults aged ≥70 years, using cross-sectional data from NHANES 2009–2010 and 2017–2018. Flavonoid intake was estimated from two 24-hour dietary recalls and categorized as low or high based on the median intake (85.4 mg/day). Hearing impairment was defined using pure-tone average (PTA) >25 dB in one or both ears. Among the 1,492 participants, 55.7% had bilateral hearing impairment, 15.6% had unilateral hearing impairment, and 28.7% had normal hearing. These categories were mutually exclusive, based on the presence of hearing impairment in one or both ears. After adjusting for sociodemographic, behavioral, and dietary covariates, low flavonoid intake was associated with a 45% greater odds of bilateral hearing impairment (adjusted odds ratio = 1.45; 95% confidence interval: 1.03–2.04; p = 0.034), but not associated with unilateral impairment. Marginal associations were also observed for specific flavonoid subclasses, including flavan-3-ols and catechins. A significant interaction with age was observed, with the positive association between higher flavonoid intake and severe hearing loss evident only in adults aged 70–75 years. These findings suggest that low flavonoid intake may be a modifiable dietary factor associated with age-related bilateral hearing loss. Increasing dietary flavonoid consumption may be associated with benefits for sensory health and could play a modest role in reducing the risk of hearing impairment in older adults, though further research is needed to confirm these findings.

This study examined factors associated with stunting in children aged < 2 years in eastern Indonesia. Data were derived from three national cross-sectional surveys of Indonesia. The outcome variable was stunting (low length-for-age) in children aged < 2 years. Nineteen potential predictors from community- to individual-level characteristics were identified. Multilevel analyses were performed, adjusting for cluster sampling with random effects for cluster and strata. We used data from the 2010, 2013 and 2018 Indonesian Basic Health Research. Information from 6076 children aged < 2 years from Nusa Tenggara Barat, Nusa Tenggara Timur, Sulawesi, Maluku and Papua regions were used. We found that the proportion of stunted children aged < 2 years in eastern Indonesia decreased between 2010 and 2018. Significant predictors of stunting included living in West Nusa Tenggara (adjusted OR (aOR) = 1·09; 95 % CI 1·02, 1·16) and East Nusa Tenggara region (aOR = 1·36; 95 % CI 1·28, 1·45), belonging to a household with three or more children aged under 5 years (aOR = 1·32; 95 % CI 1·11, 1·56), being from a poor household (aOR = 1·17; 95 % CI 1·06, 1·30) and born to less educated mother (aOR = 1·26; 95 % CI 1·02, 1·56). Furthermore, stunting were more likely among males (aOR = 1·29, 95 % CI 1·19, 1·40), those aged 12–23 months (aOR = 2·01; 95 % CI 1·65, 2·45), with low birth weight (aOR = 1·91; 95 % CI 1·40, 2·60) and with gestational age < 37 weeks at birth (aOR = 1·14; 95 % CI 1·05, 1·24). Multiple factors contribute to stunting in eastern Indonesia, highlighting the need for comprehensive and targeted initiatives. Poverty reduction, healthcare system improvement, family planning and continued health promotion strategies are necessary to reduce stunting prevalence.

Callery pear (Pyrus calleyana Decne.) is a problematic woody invasive plant in eastern North America that invades old fields, forests, and disturbed sites. While management guidance typically suggests foliar, basal bark, cut stump, and hack-and-squirt applications of herbicides for P. calleryana, there is a dearth of studies focusing on the efficacy of specific treatments. We evaluated seven herbicide treatments for control of midstory P. calleryana. Cut stump and hack and squirt applications of glyphosate, imazapyr, and triclopyr and a soil application of hexazinone were repeated at six sites within Georgia, Kansas, and South Carolina, and all study trees were monitored for approximately one year after herbicide application. Cut stump applications of glyphosate, imazapyr, and triclopyr provided the most consistent control with no resprouting and 100% mortality. Hack-and-squirt applications of glyphosate and triclopyr resulted in approximately 80% probability of mortality one year after treatment, while hack-and-squirt application of imazapyr and soil application of hexazinone averaged only 20 and 25% probability of mortality, respectively. Our results demonstrate the efficacy of seven treatment options for P. calleryana control in three geographic locations with varied habitat types, and our data suggest that cut stump applications of glyphosate, imazapyr, or triclopyr or hack-and-squirt application of glyphosate or triclopyr may be useful for reducing populations of P. calleryana. that have grown past the sapling stage.

Lygus hesperus is an economically important pest of many crops. An effective monitoring method for the early detection of L. hesperus could improve its management. A recently developed pheromone lure has been shown to attract L. hesperus males, however, fewer males were captured than expected. It is unknown whether this was an effect of pheromone responsiveness or the type of trap used. Thus, we compared the efficacy of the previously used white delta sticky traps to red cylindrical sticky traps in strawberry fields in California and cotton fields in Arizona. Collections were made 1 and 2 weeks after trap deployment. In strawberry, pheromone baited traps captured more L. hesperus males than unbaited traps. More males were collected from baited red cylindrical sticky traps compared with either type of unbaited trap. In cotton, baited red cylindrical traps captured more males than unbaited traps after 1 week of field exposure, but not after 2 weeks of deployment. Overall, red cylindrical traps caught more L. hesperus males than white delta traps. Diminished trap captures during the second week of monitoring may be attributed to high temperatures in cotton that likely shortened the lure’s longevity and windy conditions in both strawberry and cotton that may have decreased the effectiveness of the trap’s adhesive. Additional work to clarify the lure’s field longevity and distinguish various elements of trap design (e.g. colour, adhesive, and shape) may further increase the operational effectiveness of pheromone-baited traps for L. hesperus.

Trophy hunting (TH) is a form of wildlife use in which individuals pay to hunt under regulated conditions and retain selected body parts as trophies. Tanzania permits TH in areas with different land-use designations, covering diverse habitats. However, human activities such as settlement, agriculture and livestock grazing can threaten habitats and wildlife populations, particularly as revenue from TH declines. Using satellite data from between 2013 and 2023, we quantified changes in functional area and land cover across 15 hunting blocks in northern Tanzania. Over this period, functional area in hunting blocks decreased by c. 22.4% in Game Controlled Areas (GCAs) and by c. 18.0% in Open Areas (OAs), attributed to human encroachment. Longido North GCA experienced the most substantial land-cover change, with a 76% increase in dense vegetation. An analysis comparing the 2013–2019 and 2019–2023 data revealed consistent shrinkages in grassland and mixed and dense vegetation within the Longido North GCA, Masai OA and Irkishbor OA hunting blocks. Although individual land-cover losses in the given periods remained below 50% (our threshold for major habitat loss), these cumulative changes reduce habitat suitability, posing risks to biodiversity and the sustainability of TH. This study reveals the extent of human pressures on hunting blocks and calls for integrated regional planning, active management and targeted conservation strategies.

Chronic stress can lead to serious health problems, including elevated blood glucose, intestinal dysbiosis, villous shortening, decreased enzyme activity and hepatic steatosis. Here, we investigate the protective effects of the magnesium-L-theanine (Mg-T) combination on chronic variable stress (CVS)-induced liver and intestinal damage. Fifty-six rats were divided into two groups: normal and stressed, and supplemented with different doses of Mg-T (0, 100, 200 and 400 mg/kg). The results showed that CVS-treated rats had reduced body weight, serum insulin levels, magnesium levels, intestinal barrier proteins and nutrient transporters. However, Mg-T supplementation improved these parameters in a dose-dependent manner. Mg-T treatment reduced CVS-induced glucose, corticosterone and triglyceride levels while alleviating liver and intestinal damage. Histological analysis revealed that Mg-T alleviated CVS-induced intestinal damage, characterised by villus shortening, reduced crypt depth and inflammation. CVS-induced increases in hepatic triglycerides and lipogenic markers (SREBF1, FASN) were attenuated by Mg-T supplementation, while metabolic regulators such as PPARγ and SIRT-1 were upregulated. Moreover, Mg-T restored the expression of intestinal barrier proteins (Claudin-1, Occludin, ZO-1) and mucosal protein (MUC-2). CVS treatment reduced the expression of nutrient transporters (SGLT1, GLUT2) and amino acid carriers; however, Mg-T supplementation increased the protein levels of these markers. Our data demonstrate that Mg-T has significant protective effects against CVS-induced metabolic, hepatic and intestinal disturbances, highlighting its potential as a therapeutic intervention for managing chronic stress-related health problems.

Evidence for parasites in the fossil record is rare. As such, any examples present insight into parasitism in deep time. Trilobites have often been used for documenting parasites in the Paleozoic. Here we examine an Illaenus sp. pygidium from the Middle Ordovician of Estonia that displays thirteen small structures with domical to crater-like shapes. These morphologies are consistent with circular depressions on the pygidium inner surface. We propose that these structures formed while the trilobite was alive and record an infestation located within soft tissue. The trace maker seems to have influenced pygidial mineralization and caused a pathological reaction. The symbiont may have been capable of bioerosion, excavating these depressions by dissolving the trilobite’s mineral tissues; however, this scenario is less likely considering comparisons with syndromes and pathologies known in modern arthropods. The parasitic organism may have fed on the trilobite’s tissues or utilized nutrients within the trilobite’s body for growth. These observations are consistent with a parasitic organism.

Neonatal growth assessment during the first 28 days of life is a critical determinant of infant health and survival. Anthropometric measurements provide a simple, inexpensive, and non-invasive means to evaluate neonatal size, nutritional status, and growth, as well as to predict long-term health outcomes. Alongside standard growth curves, methods for assessing neonatal body composition offer additional insights into fat and fat-free mass distribution, which are linked to later risks such as childhood obesity and metabolic complications. This review summarizes the commonly used anthropometric measures and advanced laboratory techniques for assessing neonatal growth and body composition, discusses their advantages and limitations, and highlights the importance of their combined use in clinical and research settings. Understanding these methods is essential for early identification of growth disturbances and for promoting optimal nutrition and health outcomes throughout the life course.

Consumers tend to perceive certain foods as more natural and in turn as more nutritious. Thus, this study aimed to evaluate the nutritional quality, the degree of naturalness, and their association with animal-based and plant-based food products. A total of 1275 food products were collected by the Food Quality Observatory in Québec (Canada) between 2018 and 2022. These products were divided into five categories: sliced processed meats (n = 477), yogurts and dairy desserts (n = 344), sausages (n = 266), processed cheese products (n = 96) and plant-based alternatives (n = 92) within these four categories. The overall nutritional quality was evaluated using the Nutri-Score and the front-of-package (FOP) nutrition symbol recently implemented in Canada, while the degree of naturalness was measured using the Food Naturalness Index (FNI). Yogurts and dairy desserts as well as plant-based alternatives had lower Nutri-Score and thus, higher nutritional quality compared to other food categories. The FOP symbol for foods high in saturated fat or sodium was more common in sliced processed meats and sausages. FNI scores were higher in processed cheese products than in other categories, indicating a greater degree of naturalness. Correlations between nutritional quality and food naturalness varied depending on the food category and the nutrient profiling model, with Spearman coefficients being positive or negative and ranging from weak to moderate. This study supports the idea that food naturalness and nutritional quality offer complementary information depending on the food category. Further research in other food categories would help to better understand the associations between the two concepts.

A total of 12 ostracodes species belonging to 10 genera are reported for the first time from the lower Pliocene Takikawa Formation in Takikawa City, Hokkaido, northern Japan. The ostracode fauna of the formation includes both cryophilic and circumpolar species. Cryophilic species are Baffinicythere robusticostata Irizuki, 1996, Neomonoceratina tsurugasakensis (Tabuki, 1986), and Yezocythere hayashii Hanai and Ikeya, 1991, and circumpolar species are Palmenella limicola (Norman, 1867) and Semicytherura mainensis (Hazel and Valentine, 1969). The co-occurrence of cryophilic and circumpolar species suggests that the marine environment was strongly influenced by extremely cold water masses. The species diversity and equitability of the fossil ostracode assemblages indicate that the depositional topography was the inner area of a bay. One new genus and one new species, Woodeltia sorapuchiensis new genus new species, are described. This new genus occurred in a temperate environment in Japan, in the early Miocene. In the early Pliocene, Woodeltia adapted to cold environmental conditions in Hokkaido. We hypothesize that Woodeltia sorapuchiensis is an important species for Woodeltia, showing the group’s adaptation to cold environments and migration to the coast of North America.

The welfare of fast-growing broiler chickens (Gallus gallus domesticus) raised in intensive farming systems is of global concern for the public, animal advocates and animal welfare scientists. This study investigated the animal husbandry factors which affect broiler chicken welfare on farms in West Java, Indonesia. Foot-pad dermatitis (FPD) and hock burn (HB) were used as welfare indicators with data collected from 14 farms across West Java. Welfare Quality® data were collected from 150 chickens from six locations on each farm, a total of 2,104 chickens, alongside data on the husbandry management and micro-climate inside the chicken house. Cumulative Link Mixed Models (CLMM) were employed using the ordinal package in R to analyse environmental predictors of welfare indicators. Litter quality and breed of chicken were predictors of FPD, whereas litter quality, bodyweight, light intensity, humidity, wind and CO2 predicted HB. There was wide variation in the FPD scores between farms. Sampling locations at the door end of the chicken houses showed consistently worse litter scores, welfare outcomes, and higher variation in micro-climate compared to areas near the negative pressure fans. Chickens were usually sent for slaughter at 32 days, which resulted in better welfare outcomes compared to other countries reported in the literature, where chickens are usually slaughtered at an older age and heavier bodyweight. This research could form the basis for better welfare standards on broiler chicken farms in Indonesia.

Anurans are bioindicators and key components of ecosystem functions. Although South America harbors more than 4,000 identified anuran species, fewer than 10% have been analyzed regarding their trematode fauna. When tadpoles are considered, the paucity of studies becomes even more evident. Considering the ability of digeneans to serve as indicators of ecosystem health, it is evident that there is a gap in the knowledge of trematodes occurring in anuran biodiversity hotspots. Herein, we provide an ecological and morphological analysis of the trematode component community recovered in tadpoles and adult anurans. During a long-term herpetological and helminthological study conducted in a Cerrado fragment in Brazil, 569 anurans from 17 species were necropsied. Eleven species were common to both adults and tadpoles, and six species occurred only in adults. The total prevalence was 61% (352/569), in separate analyses, 65% (192/296) for adult anurans, and 58% (160/273) for tadpoles. A total of 12,397 trematodes belonging to 16 taxa were recovered. The component community was composed mostly of metacercariae. We provided a brief morphological description for each trematode taxa recovered. Additionally, statistical analysis was performed to elucidate the differences between tadpoles and adult anurans trematode communities. The trematode community analyzed in our study revealed 24 new host records and was the first to include tadpoles in such an analysis, highlighting the importance of faunistic inventories for a better understanding of parasitism in their hosts, as well as providing a foundation for further research.

Late-season escapes of Palmer amaranth and waterhemp (both are Amaranthus species) pose a significant challenge in cotton production due to their high fecundity, herbicide resistance, and ability to replenish the weed seedbank at harvest. While harvest weed seed control (HWSC) has been adopted in grain systems, its feasibility in cotton remains unknown due to differences in cotton harvesting equipment design. Therefore, this study aimed to determine the fate of Amaranthus spp. seeds during harvest with cotton pickers and stripper harvesters, and evaluated the efficacy of an impact mill to destroy a range of weed seeds present in different types of cotton debris. Along with the seed cotton, cotton strippers removed 52% of the Amaranthus seeds, compared with just 7% with pickers, which are then cleaned at the cotton gin. About 85% of the seeds were retained on the plant after harvest by the pickers, and about 15% by the strippers. Seeds shattered to the ground accounted for 8% with pickers and 18% with strippers. Additionally, the cotton stripper’s field cleaner mechanism removed 15% of the weed seeds. Together, seeds collected in seed cotton, retained on the plant, or separated by field cleaners (in strippers) represent points for HWSC implementation. Different types of cotton debris were then run through a stationary weed-seed impact mill with a known number of seeds for seven weed species to determine seed destruction efficacy. The stem debris had a 29% moisture content, which is too high for the impact mill and caused mill clogging; however, seed kill levels of 98% were achieved in bur debris and gin debris types, values similar to those reported in grain systems. Together, these findings provide a framework for incorporating HWSC practices into cotton, offering growers and processors a way to reduce weed seedbank inputs.

We sought to identify risk factors for coagulase-negative staphylococcal (CoNS) surgical site infection (SSI). Risk factors associated with an increased risk of CoNS SSI include male sex and asthma or COPD. Colon surgery was associated with a reduced risk of CoNS SSI.

Nematode records and specimens from the South Australian Museum, Australian Museum, CSIRO Wildlife Collection, Queensland Museum, Western Australian Museum, and Natural History Museum, London, of 1107 individuals of Rattus fuscipes were examined. The nematode community comprised 19 families, 36 genera, and 44 identified species. Mastophorus muris and unidentified heligmonellids were recovered from 4 individuals of R. f. fuscipes. Rattus f. assimilis was infected with 40 identified species of nematode from 955 individuals; R. f. coracius 18 species from 107 individuals; and R. f. greyii 8 species from 28 individuals. Rattus fuscipes harboured 18 species in Northern Queensland, 27 species in Southern Queensland, 27 species in New South Wales, 19 species in Victoria, and 8 species in South Australia. A bootstrap analysis of the R. f. greyii nematode community indicated that 91.3% of species had been found. No core species were revealed. The Trichostrongylidae dominated with Nippostrongylus magnus, and Odilia emanuelae occurring in all the populations. Nippostrongylus magnus, 43% prevalence, in Victoria and Physaloptera troughtoni, 42% prevalence, in South Australia were secondary species. Sorensen’s indices indicated that R. f. assimilis and R. f. coracius had the most similar nematode communities, 54.8%. Overall, the Northern and Southern Queensland populations were most similar (77.3%) and the New South Wales and South Australian populations least similar (22.9%). The identifications of Heterakis spumosa, Physaloptera troughtoni, Rictularia mackerrasae, and Pterygodermatites pearsoni were confirmed. The species composition of the nematode community of R. fuscipes suggested a scenario of coevolution, host switching, recently acquired and occasional infections in a community of cosmopolitan, regional, and indigenous species. Species throughout the component communities of R. fuscipes indicated that climate and habitat were also determinants of species composition.
