For >2 years, Japan's government has been urging the populace to take countermeasures to prevent COVID-19, including mask wearing. We examined whether these preventive behaviors have affected the rate and degree of sensitization against pollen and house dust antigens in patients with allergic rhinitis. We retrospectively surveyed 2565 patients who had undergone allergy blood testing during the period 2015–2021. We subdivided this period into eras based on the COVID-19 pandemic: the pre-COVID (2015–2019, n = 1879) and COVID (2020–2021, n = 686) eras. The positive rates for Japanese cedar and cypress in the 40–59-year-olds and those for house dust in the 20–39-year-olds were significantly reduced in the COVID era versus those in the pre-COVID era. Each group's mean antigen-specific CAP scores decreased significantly from the 1st to 2nd era: from 1.98 to 1.57 for cedar (p < 0.01), 1.42 to 0.95 for cypress (p < 0.05), and 2.86 to 2.07 for house dust (p < 0.01). Our survey of the patients' clinical records indicates that 47.5% of the pollinosis patients reported improvement in nasal symptoms after the three seasons of pollen dispersion in the COVID era. Japan's quarantine policies designed to combat the spread of COVID-19 thus coincide with pivotal measures to alleviate allergic reactions.

The increasing healthcare cost imposes a large economic burden for the Japanese government. Predicting the healthcare cost may be a useful tool for policy making. A database of the area-basis public health insurance of one city was analyzed to predict the medical healthcare cost by the dental healthcare cost with a machine learning strategy. The 30,340 subjects who had continued registration of the area-basis public health insurance of Ebina city during April 2017 to September 2018 were analyzed. The sum of the healthcare cost was JPY 13,548,831,930. The per capita healthcare cost was JPY 446,567. The proportion of medical healthcare cost, medication cost, and dental healthcare cost was 78%, 15%, and 7%, respectively. By the results of the neural network model, the medical healthcare cost proportionally depended on the medical healthcare cost of the previous year. The dental healthcare cost of the previous year had a reducing effect on the medical healthcare cost. However, the effect was very small. Oral health may be a risk for chronic diseases. However, when evaluated by the healthcare cost, its effect was very small during the observation period.

Popularmente conhecidas como ampulárias, esses moluscos gastrópodes são usualmente cultivados como organismos ornamentais pelo mundo. A coloração desses animais ornamentais é um dos pontos que atrai os seus admiradores e estimula sua aquisição no mercado. O pigmento mais difundido como suplemento para intensificação de cor em organismos aquáticos é a astaxantina. Ainda não existem rações específicas para a ampulária reforçando a necessidade de testar alternativas de alimentos e suplementos que melhorem o desempenho produtivo e a atratividade do animal. Os objetivos desse estudo foram mensurar a capacidade de acumulação de astaxantina sintética em diferentes níveis de inclusão na dieta de Pomacea diffusa, sua influência na concentração do pigmento e nos índices zootécnicos ao final do cultivo. E em paralelo verificar a influência da mudança da dieta de ração de peixes para ração de camarão na condição corporal dos moluscos em comparação com o início do trabalho. As ampulárias alimentadas com ração comercial extrusada para camarão marinho tiveram baixos índices de conversão alimentar (126,7 ± 18,3), altos índices de eficiência alimentar (126,7 ± 18,3%) e fator de condição (1,0 ± 0,14) acima da média inicial (0,90 ± 0,17), o que demonstra que esse alimento pode ser utilizado para seu cultivo. A suplementação dietética de astaxantina sintética não resulta em aumento significativo da concentração desse pigmento na musculatura desse molusco (P˃0,05).

Abstract
Known as apple snail, these gastropods are popular as aquarium pets around the world. The bright color of these animals is one of the key points that attract their attention in the ornamental aquaculture, where deep-colored animals are well appreciated. Astaxanthin is the most widespread color enhancing pigment used as a food supplement for aquatic organisms. There is no specific commercial food for apple snails, emphasizing the need to search for food alternatives and supplements that improve their performance and attractiveness. The objectives of this study are to measure the synthetic astaxanthin accumulation capacity of Pomacea diffusa at different levels of diet supplementation, and the effect on pigment concentration and zootechnical indexes at the end of the culture. It was also aimed to verify the effect of the diet change from fish food to extruded shrimp food on the mollusks' body condition. Apple snails fed with commercial shrimp ration had low feed conversion rates (0.81 ± 0.13), high food efficiency (126.7 ± 18.3%), and condition factor (1.0 ± 0.14) above the initial average (0.90 ± 0.17), demonstrating that this might be an advantageous alternative food. Dietary supplementation with synthetic astaxanthin did not result in a significant concentration increase of this pigment in muscle tissue of these mollusks (P˃0.05).

In 2016, the World Health Assembly passed a resolution to eliminate viral hepatitis as a public health threat by 2030. We aimed to examine the status of the global viral hepatitis response. Methods: In 2017, the World Health Organization (WHO) asked the Ministries of Health in all 194 Member States to complete a Country Profile on Viral Hepatitis policy uptake indicators, covering national plans/funding, engagement of civil society, testing guidance, access to treatment, and strategic information. Results: Of 194 Member States, 135 (70%) responded, accounting for 87% of the global population infected with hepatitis B virus (HBV) and/or C virus (HCV). Of those responding, 84 (62%) had developed a national plan, of which, 49 (58%) had dedicated funding, and 62 (46%) had engaged with civil society; those engaged with civil society were more likely to have a funded plan than others (52% vs. 23%, p = 0.001). Guidance on testing pregnant women (for HBV) and people who inject drugs (for HCV) was available in 70% and 46% of Member States, respectively; 59% and 38% of Member States reported universal access to optimal therapies for HBV and HCV, respectively. Conclusions: Most people living with hepatitis B and C reside in a country with a national hepatitis strategy. Governments who engaged with civil society were more advanced in their response. Member States need to finance these national strategies and ensure that those affected have access to hepatitis services as part of efforts to achieve universal health coverage. Lay summary: The World Health Organization's goal to eliminate viral hepatitis as a public health threat by 2030 requires global action. Our results indicate that progress is being made by countries to scale-up national planning efforts; however, our results also highlight important gaps in current policies.

The Japanese government began a human papillomavirus (HPV) vaccination program for girls aged 12‐16 years in 2010 but withdrew its recommendation in 2013 because of potential adverse effects, leading to drastically reduced vaccination uptake. To evaluate population‐level effects of HPV vaccination, women younger than 40 years of age newly diagnosed with cervical intraepithelial neoplasia grade 1‐3 (CIN1‐3), adenocarcinoma in situ (AIS), or invasive cervical cancer (ICC) have been registered at 21 participating institutes each year since 2012. A total of 7709 women were registered during 2012‐2017, of which 5045 were HPV genotyped. Declining trends in prevalence of vaccine types HPV16 and HPV18 during a 6‐year period were observed in CIN1 (50.0% to 0.0%, P (trend) < .0001) and CIN2‐3/AIS (83.3% to 45.0%, P (trend) = .07) only among women younger than 25 years of age. Overall, HPV vaccination reduced the proportion of HPV16/18‐attributable CIN2‐3/AIS from 47.7% to 33.0% (P = .003): from 43.5% to 12.5% as routine vaccination (P = .08) and from 47.8% to 36.7% as catch‐up vaccination (P = .04). The HPV16/18 prevalence in CIN2‐3/AIS cases was significantly reduced among female individuals who received their first vaccination at age 20 years or younger (P = .02). We could not evaluate vaccination effects on ICC owing to low incidence of ICC among women aged less than 25 years. We found HPV vaccination to be effective in protecting against HPV16/18‐positive CIN/AIS in Japan; however, our data did not support catch‐up vaccination for women older than 20 years. Older adolescents who skipped routine vaccination due to the government's suspension of its vaccine recommendation could benefit from receiving catch‐up vaccination before age 20 years.

This work provides a comprehensive CpG methylation landscape of the different layers of the human eye that unveils the gene networks associated with their biological functions and how these are disrupted in common visual disorders. Herein, we firstly determined the role of CpG methylation in the regulation of ocular tissue-specification and described hypermethylation of retinal transcription factors (i.e., PAX6, RAX, SIX6) in a tissue-dependent manner. Second, we have characterized the DNA methylome of visual disorders linked to internal and external environmental factors. Main conclusions allow certifying that crucial pathways related to Wnt-MAPK signaling pathways or neuroinflammation are epigenetically controlled in the fibrotic disorders involved in retinal detachment, but results also reinforced the contribution of neurovascularization (ETS1, HES5, PRDM16) in diabetic retinopathy. Finally, we had studied the methylome in the most frequent intraocular tumors in adults and children (uveal melanoma and retinoblastoma, respectively). We observed that hypermethylation of tumor suppressor genes is a frequent event in ocular tumors, but also unmethylation is associated with tumorogenesis. Interestingly, unmethylation of the proto-oncogen RAB31 was a predictor of metastasis risk in uveal melanoma. Loss of methylation of the oncogenic mir-17-92 cluster was detected in primary tissues but also in blood from patients. ; The research leading to these results was supported by European Research Council Advanced Grant EPINORC, RecerCaixa Foundation, Federación Española de Enfermedades Raras (FEDER), Federación Española de Enfermedades Neuromusculares (ASEM), Fundación Isabel Gemio, COST CM1406, Instituto de Salud Carlos III (PI/00816) and Health and Sciences Departments of the Catalan Government (Generalitat de Catalunya).
