- Abstract
Cooking parameters elaborated in the U.S. Department of Agriculture's Food Safety and Inspection Service Cooking Guideline for Meat and Poultry Products (Appendix A) were evaluated for inactivation of Salmonella spp. in pot pies. To prepare dough for pot pies, flour, butter, sugar, salt, and water were mixed, portioned into balls (65 or 85 g each), flattened (ca. 13 or 15 cm diameter, ca. 0.5 cm thick), and hand-pressed into pans (ca. 19.4 cm diameter). Next, a 100-g portion of beef, chicken, or a meat alternative, with or without added gravy (55 g of protein and 45 g of gravy), was inoculated with a cocktail of Salmonella spp. (ca. 6.5 or 7.9 log CFU/g of filling) and distributed onto the pie crust. After covering with a 65-g sheet of dough, pies were heat sealed in nylon polyethylene bags and stored at -20 °C for up to 72 h. Frozen pot pies containing a beef or meat alternative filling were cooked in a convection oven to an internal temperature of 57.8 °C (136°F) instantaneous, 62.8 °C (145°F) and held for 4 min, 67.2 °C (153°F) and held for 34 sec, or 71.1 °C (160°F) instantaneous; whereas chicken pot pies were cooked to an internal temperature of 57.8 °C (136°F) instantaneous, 62.8 °C (145°F) and held for 13 min, 67.2 °C (153°F) and held for 96 sec, or 73.9 °C (165°F) instantaneous. Cells of Salmonella spp. were recovered from uncooked or cooked pot pies by stomaching each pie in peptone water and enumerating pathogen levels via direct plating. Cooking delivered Salmonella spp. reductions of ca. 3.6 to ≥6.3 log CFU/g of pot pie. With few exceptions, when pathogen levels decreased to below detection by direct plating (0.5 log CFU/g of pot pie), cells of Salmonella were not recovered by enrichment. In addition, there were minimal differences in the a
w and moisture content of the protein filling before and after cooking, suggesting that enclosing a meat, poultry, or meat alternative filling within a dough wrapping maintained moisture in the filling during the cooking process., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Published by Elsevier Inc.)- Published

- Abstract
Objective: To provide healthcare professionals guidance on youth at risk for prolonged recovery and post-traumatic headache (PTH), and on pharmacologic and non-pharmacologic management of PTH due to concussion and mild traumatic brain injury., Background: Headache is the most common persistent post-concussive symptom affecting 8% of youth for >3 months after concussion. Over the past decade, many studies have explored the treatment of PTH in youth, but there are no established guidelines., Methods: This white paper is based on a synthesis of an updated systematic review of the literature on treatment of PTH and a narrative review of the literature on risk factors for prolonged recovery and health disparities. Results were interpreted by a group of expert providers in PTH in children and adolescents through collaboration of the PTH and pediatric special interest groups of the American Headache Society., Results: Factors that consistently were associated with prolonged recovery from concussion and persistent PTH included female sex, a high number of acute symptoms, and adolescent age. Social determinants of health also likely play an important role in PTH and deserve consideration in the clinical and research settings. A total of 33 studies met the criteria for inclusion in the systematic review of PTH treatment in youth, although most were retrospective and of fair-to-poor quality. Treatment strategies included acute and preventive pharmacologic management, procedures, neuro-modulatory devices, physical therapy, physical activity, and behavioral health support. A collaborative care approach that includes a thoughtful combination of these management strategies is likely most effective., Conclusions: This white paper provides a roadmap for tailoring the treatment of PTH based on factors influencing prolonged headache, the timing of therapies, and therapies with the most evidence for treating PTH in youth. We also highlight research needed for developing more definitive guidelines on PTH management in youth., (© 2024 The Author(s).

- Abstract
Background: Elevated risk of psychosis for ethnic minority groups has generally been shown to be mitigated by high ethnic density. However, past survey studies examining UK Pakistani populations have shown an absence of protective ethnic density effects, which is not observed in other South Asian groups., Aims: To assess the ethnic density effect at a local neighbourhood level, in the UK Pakistani population in East Lancashire., Method: Data was collected by the East Lancashire Early Intervention Service, identifying all cases of first episode psychosis (FEP) within their catchment area between 2012 and 2020. Multilevel Poisson regression analyses were used to compare incidence rates between Pakistani and White majority groups, while controlling for age, gender and area-level deprivation. The ethnic density effect was also examined by comparing incidence rates across high and low density areas., Results: A total of 455 cases of FEP (364 White, 91 Pakistani) were identified. The Pakistani group had a higher incidence of FEP compared to the White majority population. A clear effect of ethnic density on rates of FEP was shown, with those in low density areas having higher incidence rates compared to the White majority, whereas incidence rates in high density areas did not significantly differ. Within the Pakistani group, a dose-response effect was also observed, with risk of FEP increasing incrementally as ethnic density decreased., Conclusions: Higher ethnic density related to lower risk of FEP within the Pakistani population in East Lancashire, highlighting the impact of local social context on psychosis incidence.

- Abstract
Background: Occupational therapists can play a key role in early identification of delay at the population health level by providing education to public health employees on how to implement developmental monitoring with caregivers of children birth to age 5., Methods: A pretest posttest design was utilized to assess the online education and training that was provided to Department of Public Health employees ( N = 339), including Head Start, Special Supplemental Nutrition Program for Women, Infants and Children, Home Visiting, and Early Intervention., Results: Analysis of pretest-posttest survey data showed significant results for all 12 key learning outcomes. Six out of 12 outcomes were found to have a large effect size ( d > 0.8), 4 outcomes indicated a medium effect size ( d > 0.5), and 2 outcomes had a small effect size ( d > 0.2). Participants gained knowledge of the "Learn the Signs. Act Early." (LTSAE) developmental monitoring program, the difference between developmental monitoring and screening, the state's referral system and age-appropriate parental engagement activities through knowledge of child development., Conclusions: Occupational therapists are child development specialists who can provide education on developmental monitoring and activities for parental engagement. The online course proved to be an effective platform to promote LTSAE within state agencies., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.

- Abstract
The development of new data storage solutions is crucial for emerging digital technologies. Recently, all-optical magnetic switching has been achieved in dielectrics, proving to be faster than traditional methods. Despite this, single-molecule magnets (SMMs), which are an important class of magnetic materials due to their nanometre size, remain underexplored for ultrafast photomagnetic switching. Herein, we report femtosecond time-resolved K-edge X-ray absorption spectroscopy (TR-XAS) on a Mn(III)-based trinuclear SMM. Exploiting the elemental specificity of XAS, we directly track nuclear dynamics around the metal ions and show that the ultrafast dynamics upon excitation of a crystal-field transition are dominated by a magnetically active Jahn-Teller mode. Our results, supported by simulations, reveal minute bond length changes from 0.01 to 0.05 Å demonstrating the sensitivity of the method. These geometrical changes are discussed in terms of magneto-structural relationships and consequently our results illustrate the importance of TR-XAS for the emerging area of ultrafast molecular magnetism., (© 2024.

- Abstract
Thermal inactivation studies were undertaken on Listeria monocytogenes and Salmonella spp. inoculated on the surface of country ham. Hams (average = ca. 3.4 ± 0.5 kg each; average = ca. ≥18% shrinkage) were used as provided by the processor (i.e., "salted hams"), desalted in tap water (i.e., "desalted hams"), or dried for an additional period (i.e., "extra-dried hams"). Hams were surface inoculated (ca. 9.5 log CFU/ham) with a multistrain cocktail of L. monocytogenes or Salmonella spp. and cooked within a bag ina circulating water bath to an internal temperature of 130°F (54.4°C) instantaneous, 145°F (62.8°C) and held for 4 min, 153°F (67.2°C) and held for 34 s, or 160°F (71.1°C) instantaneous. Regardless of ham type, all four time and temperature combinations tested herein delivered a ≥6.7-log reduction of cells of L. monocytogenes or Salmonella spp. Differences in product pH, moisture content, or a
w did not have an appreciable impact on the thermal inactivation of L. monocytogenes or Salmonella spp. on country ham. In addition, shelf-life studies were undertaken using slices of "salted" country ham that were surface inoculated (ca. 5.5 log CFU/slice) with a multistrain cocktail of L. monocytogenes or Staphylococcus aureus and then stored at 20°C. Levels of S. aureus increased by ca. ≤1.4 log CFU/slice during storage for 90 days, whereas levels of L. monocytogenes remained relatively unchanged (≤0.2 log CFU/slice increase). Our data validated that cooking parameters elaborated in the U.S. Department of Agriculture's Food Safety and Inspection Service Cooking Guideline for Meat and Poultry Products (Revised Appendix A) are sufficient to deliver significant reductions (ca. ≥6.8 log CFU/ham) in levels of L.monocytogenes and Salmonella spp. on country ham. In addition, in the event of postprocessing contamination, country ham may support the outgrowth of S. aureus or survival of L. monocytogenes during storage at 20°C for 90 days., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Published by Elsevier Inc.)- Published
