    Abstract A new family of stabilized benzylic nucleophiles for the palladium-catalyzed decarboxylative allylic alkylation reaction has been developed. Allyl esters derived from 3-carboxyphthalides were found to undergo palladium-catalyzed deallylation and decarboxylation under mild reaction conditions, a process facilitated by the formation of a stabilized aromatic anion. The regioselective allylic coupling of this intermediate afforded a variety of functionalized phthalides in 73–96% yields.

    Abstract Objective: To investigate the presence and abundance of mosquito species in containers found in different types of cemeteries in Puerto Rico to assess their importance and make control recommendations.
    Methods: We conducted surveys of containers with water in 16 cemeteries in southeastern Puerto Rico to detect the presence of larvae and pupae of Aedes aegypti and other mosquitoes; to identify the most common and productive containers and to study their variation in relation to the type of cemetery.
    Results: The most common containers with water were flowerpots, followed in abundance by a variety of discarded containers and open tombs. We found a positive relationship between density of containers with water and rainfall. There was a rich community of mosquito species developing in containers of the inspected cemeteries: nine mosquito species belonging to four genera with Ae. aegypti and Ae. mediovittatus being the most frequent and abundant. We sampled 13 cement-type cemeteries, 2 mixed and only 1 lawn cemetery, consequently, we could not draw any conclusion regarding container productivity and cemetery type.
    Conclusions: Surveyed cemeteries were important sources of Ae. aegypti and other mosquitoes in flowerpots, discarded containers and open tombs. We recommend conducting further studies to establish how frequently inspections should occur; and mosquito control by emptying aquatic habitats and larviciding to reduce mosquito productivity and protect workers and visitors from mosquito bites and possible transmission of arboviruses.

    Abstract Vaccination disparities are part of a larger system of health inequities among racial and ethnic groups in the United States. To increase vaccine equity of racial and ethnic populations, the Centers for Disease Control and Prevention (CDC) designed the Partnering for Vaccine Equity program in January 2021, which funded and supported national, state, local, and community organizations in 50 states-which include Indian Health Service Tribal Areas; Washington, DC; and Puerto Rico-to implement culturally tailored activities to improve access to, availability of, and confidence in COVID-19 and influenza vaccines. To increase vaccine uptake at the local level, CDC partnered with national organizations such as the National Urban League and Asian & Pacific Islander American Health Forum to engage community-based organizations to take action. Lessons learned from the program include the importance of directly supporting and engaging with the community, providing tailored messages and access to vaccines to reach communities where they are, training messengers who are trusted by those in the community, and providing support to funded partners through trainings on program design and implementation that can be institutionalized and sustained beyond the COVID-19 pandemic. Building on these lessons will ensure CDC and other public health partners can continue to advance vaccine equity, increase vaccine uptake, improve health outcomes, and build trust with communities as part of a comprehensive adult immunization infrastructure.

    Abstract Abstract Objective: To assess knowledge, beliefs, and behaviors concerning COVID-19 among Guatemalan, Marshallese, and Amish populations in rural Ohio; identify individual, interpersonal, community, and structural level challenges within each community; and provide population-specific recommendations to prevent and mitigate further SARS-CoV-2 transmission among these rural communities. Methods: We conducted 30 key informant interviews in four rural counties in Ohio, in May 2020. Three teams of two investigators conducted interviews with local health department staff, community members, meat packing plant management, and community leaders from three communities disproportionately affected by the COVID-19 pandemic [Guatemalan (N=12), Marshallese (N=7), Amish (N=11)]. We used the Social Ecological Model to identify and categorize themes. Results: Emerging and overall themes were identified and defined. Investigators identified COVID-19 knowledge gaps, myths, and misinformation, food insecurity, community cohesion, stigma, community culture and norms, lack of workplace safety policies, and access to testing as key themes to COVID-19 prevention. Conclusions: Understanding specific barriers and identifying facilitators that most effectively provide resources, healthcare services, education, and social support tailored to specific communities would help deter SARS-CoV-2 transmission.

    Abstract In the United States, outbreaks of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), were initially reported in densely populated urban areas (1); however, outbreaks have since been reported in rural communities (2,3). Rural residents might be at higher risk for severe COVID-19-associated illness because, on average, they are older, have higher prevalences of underlying medical conditions, and have more limited access to health care services.* In May, after a cluster of seven COVID-19 cases was identified in a rural Ohio Amish community, access to testing was increased. Among 30 additional residents tested by real-time reverse transcription-polymerase chain reaction (RT-PCR; TaqPath COVID-19 Combo Kit),

    Abstract During the COVID-19 vaccination rollout from March 2021- December 2022, the Centers for Disease Control and Prevention funded 110 primary and 1051 subrecipient partners at the national, state, local, and community-based level to improve COVID-19 vaccination access, confidence, demand, delivery, and equity in the United States. The partners implemented evidence-based strategies among racial and ethnic minority populations, rural populations, older adults, people with disabilities, people with chronic illness, people experiencing homelessness, and other groups disproportionately impacted by COVID-19. CDC also expanded existing partnerships with healthcare professional societies and other core public health partners, as well as developed innovative partnerships with organizations new to vaccination, including museums and libraries. Partners brought COVID-19 vaccine education into farm fields, local fairs, churches, community centers, barber and beauty shops, and, when possible, partnered with local healthcare providers to administer COVID-19 vaccines. Inclusive, hyper-localized outreach through partnerships with community-based organizations, faith-based organizations, vaccination providers, and local health departments was critical to increasing COVID-19 vaccine access and building a broad network of trusted messengers that promoted vaccine confidence. Data from monthly and quarterly REDCap reports and monthly partner calls showed that through these partnerships, more than 295,000 community-level spokespersons were trained as trusted messengers and more than 2.1 million COVID-19 vaccinations were administered at new or existing vaccination sites. More than 535,035 healthcare personnel were reached through outreach strategies. Quality improvement interventions were implemented in healthcare systems, long-term care settings, and community health centers resulting in changes to the clinical workflow to incorporate COVID-19 vaccine assessments, recommendations, and administration or referrals into routine office visits. Funded partners' activities improved COVID-19 vaccine access and addressed community concerns among racial and ethnic minority groups, as well as among people with barriers to vaccination due to chronic illness or disability, older age, lower income, or other factors.

    Abstract The zinc deficiency affects approximately a third of the world population, principally in the developing countries, the rural areas and in the poorest communities, where this micronutrient deficiency is one of the most prevalent risk factor for nutrientrelated diseases. This paper compiles scientific advances about the key role of the essential trace element zinc in the neurogenesis control, brain function and cognitive development. The aim of this work is to generate in health professionals, interest about the zinc deficiency effects in neuro-intellectual development and its negative impact in the cultural, economic and social development of the countries.

    Abstract Background: Onychocryptosis is one of the most common painful nail conditions. Conservative treatment may take a long time to obtain effective results.
    Objective: The purpose of this study is to show the effectiveness of a conservative treatment of ingrown nails that shows rapid results.
    Methods and materials: Patients with painful Stage 1 to 2 onychocryptosis who were not candidates or refused surgery were treated with the cotton cast. The severity and cause of onychocryptosis was clinically evaluated during a 2-month period. A questionnaire was applied to all patients to evaluate pain, final treatment, and possible complications.
    Results: All patients noticed results in less than 72 hours. Pain subsided in less than 24 hours in half of the patients and before 72 hours in 100% of the patients without the need of other treatments. The use of the cast prevented surgery and the accompanying morbidities in most of the patients (80%).
    Conclusion: The "cotton nail cast" is an effective conservative method for mild nail embedding. It is easy to apply, inexpensive, relieves pain rapidly, and avoids surgery in most patients.

    Abstract In the United States, outbreaks of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), were initially reported in densely populated urban areas (1); however, outbreaks have since been reported in rural communities (2,3). Rural residents might be at higher risk for severe COVID-19-associated illness because, on average, they are older, have higher prevalences of underlying medical conditions, and have more limited access to health care services.* In May, after a cluster of seven COVID-19 cases was identified in a rural Ohio Amish community, access to testing was increased. Among 30 additional residents tested by real-time reverse transcription-polymerase chain reaction (RT-PCR; TaqPath COVID-19 Combo Kit),† 23 (77%) received positive test results for SARS-CoV-2. Rapid and sustained transmission of SARS-CoV-2 was associated with multiple social gatherings. Informant interviews revealed that community members were concerned about having to follow critical mitigation strategies, including social distancing§ and mask wearing.¶ To help reduce the ongoing transmission risk in a community, state and county health department staff members and community leaders need to work together to develop, deliver, and promote culturally responsive health education messages to prevent SARS-CoV-2 transmission and ensure that access to testing services is timely and convenient. Understanding the dynamics of close-knit communities is crucial to reducing SARS-CoV-2 transmission.
