RESUMEN

Enteroparasitosis are diseases caused by parasitic agents present in the environment and in the gastrointestinal tract of living beings. In addition, they are still considered neglected diseases, but of great importance for public health, especially when they are related to secondary infections and currently their co-infection profile with COVID-19. The interaction of protozoa and/or helminths with the SARS-CoV-2 virus is timely and its signs and symptoms are confused with other pathogen relationships. In this way, this study aims to correlate the incidence of enteroparasitosis and COVID-19, in the pandemic period from 2020 to April 2022. This is a documentary and exploratory study of secondary data from laboratory tests of patients who were treated and diagnosed with COVID-19 and enteroparasitosis at Hospital Doutor Cloves Bezerra Cavalcante, Municipal Hospital of Bananeiras, Paraíba, Brazil. In the analysis of the database, a significant increase of approximately 48.85% in the incidence of COVID-19 cases from 2020 to 2021 stands out, remaining high until 2022. In contrast, cases of enteroparasites peaked at 48.74% in 2021, followed by an average reduction of 23.12%, with a deviation of 1.49%, in relation to the years 2020 and 2022. It was concluded that COVID-19 is predominantly associated with an increase in secondary infections, highlighting the crucial need to promote health education, improve basic sanitation and guarantee access to health services as essential components in combating the increase in parasitic infections, especially those related to viral pathologies.

As enteroparasitoses são enfermidades originadas por agentes parasitários presentes no meio ambiente e no trato gastrointestinal dos seres vivos. Ademais, ainda são consideradas doenças negligenciadas, porém de grande importância para a saúde pública, em especial, quando estão relacionadas com infecções secundárias e atualmente seu perfil de coinfecção com a COVID-19. A interação de protozoários e/ou helmintos com o vírus SARS-CoV-2 é oportuna e seus sinais e sintomas são confundidos com outras relações de patógenos. Desta maneira, este estudo visa correlacionar a incidência de enteroparasitoses e COVID-19, no período pandêmico de 2020 a abril de 2022. Trata--se de uma pesquisa documental e exploratória, de dados secundários dos exames laboratoriais de pacientes que foram atendidos e diagnosticados com COVID-19 e enteroparasitoses no Hospital Doutor Cloves Bezerra Cavalcante, Hospital Municipal de Bananeiras, Paraíba, Brasil. Na análise da base de dados, destaca-se um aumento significativo de aproximadamente 48,85% na incidência de casos de COVID-19 de 2020 a 2021, mantendo-se elevado até 2022. Em contraste, os casos de enteroparasitas atingiram um pico de 48,74% em 2021, seguido por uma redução média de 23,12%, com um desvio de 1,49%, em relação aos anos de 2020 e 2022. Conclui-se que a COVID-19 está predominantemente associada ao aumento de infecções secundárias, destacando a necessidade crucial de promover a educação em saúde, melhorar o saneamento básico e garantir o acesso aos serviços de saúde como componentes essenciais no combate ao aumento de infecções parasitárias, especialmente aquelas relacionadas a patologias virais.

RESUMEN

As a living being that was passed down the role of storytelling, I describe the conditions under which individuals find themselves. Science, and specifically public health research, affords me the opportunity to deploy my storytelling skills toward advocacy and intervention for communities that disproportionately bear the burden of poor health. Although neither role makes space for the emotional toll of this work. Neither allows me to rest long enough to move through the emotional mist of what it means to be perceived as a queer, Black, cisgender woman, and storytelling scientist in a stratified and hateful world where I am so much more. This poem pools from various worlds within me for each stanza. The poem seeks to reconcile for my whole self, and others who experience marginality, why our colleagues, countrypersons, and community members see it fit to perpetuate notions of human difference along racialized, socioeconomic, sexualized, gendered, able-bodied, and other stratified lines-to the detriment of our lives. How can my colleagues, countrypersons, and community members be willing to receive the privileges of a democratic society but discard the lives from which that society was built? How can my colleagues, countrypersons, and community members be willing to receive our science but discard our health? This poem brings together multidisciplinary discourse from the humanities and the social and biological sciences to state plainly what many others have academically. May this poem be paired with existing literature on the falsity of biologized race, reparations, and methodologies of reflexivity in science.To view the original version of this poem, see the Supplemental Material section of this article online.

RESUMEN

Food safety is a critical public health issue worldwide as the consumption of unhygienic food causes millions of illnesses annually. The contaminated food is primarily unsafe due to the presence of microorganisms (i.e. bacteria and viruses), chemicals (i.e. pesticides and heavy metals), and physical hazards (i.e. glass, metal and plastic). Foodborne illnesses such as salmonellosis, campylobacteriosis, listeriosis, E. coli infection, botulism, cholera, norovirus infection, and others are commonly caused by the problems associated with food hygiene. From the modest beginnings rooted in basic hygiene practices to the sophisticated frameworks of the modern era, the journey of food regulatory bodies has been marked by a commitment to protect consumers from the hazards associated with foodborne illnesses. In India, the 'Food Safety and Standards Authority of India sets standards, inspects food businesses, and acts against food safety violators. However, there is still more work to be done, including the effective enforcement of regulations, and thoroughly educating the consumers about food safety. The need of the hour is a multi-dimensional collaboration among different stakeholders to ensure that everyone has access to safe and nutritious food. In developing countries, the hurdles in preventing food adulteration include poor consumer awareness and insufficient resources for the enforcement of food regulations. Despite complications, the 'Food Safety and Standards Authority of India' is committed to improving food safety for consumers through cooperation with other agencies, increased enforcement, and public awareness initiatives. Developing countries face lots of challenges in regulating the safety of loose milk and street foods; including the problems of traceability, resource limitations, variety of techniques, cultural acceptance, and financial concerns. A multifaceted strategy that includes infrastructural development, consumer education, regulatory strengthening, and technological acceptance is needed to overcome all these problems linked to the safety of street foods and loose milk. Food regulators must set strict guidelines, conduct regular inspections, and licenses and training for various stakeholders involved. Proper education for customers should increase awareness and provide them with the latest information related to food safety. Access to clean water, sanitary facilities, waste management, and technological adoption should be the main priorities of infrastructure development. Challenges of traceability and labelling in loose milk and street foods include the threats of adulteration, inability to determine the origin, and improper labelling. Vendor registration, uniform labelling, stringent enforcement of food safety regulations, improved supply chain monitoring, consumer education, and technological adoption are all necessary to fully address these problems of food safety.

RESUMEN

OBJECTIVES: The aim of this study was to analyze the modeling methodologies of fiscal policies on food with health or environmental outcomes. BACKGROUND: Evidence suggests that fiscal policies on food can contribute to addressing the growing burden of noncommunicable diseases and climate change. These policies should be modeled in advance to see the implications for the environment and health. METHODS: A systematic review was conducted of studies that modeled fiscal policies on the food groups targeted by the EAT-Lancet Commission and examined their health or environmental outcomes. The Scopus and PubMed databases were searched on November 30, 2021. The records were double-screened and data on modeling methods were extracted from the included studies. RESULTS: A total of 55 studies were included in the review. The most frequently modeled interventions were fruit and vegetable subsidies (n = 19) and carbon taxes on food (n = 17). One study also included a consumer education campaign to enhance the effect of fiscal policy. The outcomes are highly sensitive to consumption change and price elasticities. None of the studies modeled the health effects of environmental outcomes. CONCLUSIONS: A model that covered all the relevant aspects of the issue was not found. Some parts were missing from all the included models. It is advisable to model the stability of the amount of diet consumed, either by keeping the amount of food in the diet stable or by taking a more conservative approach and keeping the consumed calories stable. It is preferable to keep the included diseases and environmental boundaries broad to have more valid outcome estimates on this complex issue. A more comprehensive understanding of fiscal policies would allow us to better anticipate the impact of our actions and inactions and thus could lead to more sophisticated measures taken by policymakers. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. 2022 CRD42022291945/.

RESUMEN

Objectives　This study aimed to analyze and clarify the role of public health nurses (PHNs) in assisting mothers who need assistance during antenatal checkups.Methods　This study was conducted in core city, A. The study participants were PHNs who experienced supporting at least three mothers who required support during maternity health checkups. We interviewed the respondents about their observations, decision points, difficulties in coordination, and other aspects of support. Data were extracted from verbatim transcripts and analyzed inductively.Results　Sixteen PHNs participants had an average of 9.3 years of experience. The analysis included 10 categories, 43 subcategories, and four themes. PHNs connected with mothers early depending on the mothers' wants, based on information gathered during the gestational period (theme 1). PHNs make early telephone visits to mothers based on information obtained during the gestational period. If the mother did not respond to the initial visit, the PHNs attempted to establish contact through other means.PHNs carefully observed and assessed mothers' childcare routines and mental and physical conditions (theme 2). To assess the mothers' mental health status, they were interviewed in detail using the Edinburgh postnatal depression scale. Determining the mother's condition was challenging; therefore, several PHNs conducted multiple visits and repeated the observations to achieve accurate assessments.The PHNs stayed close to their mothers and carefully supported them toward independence while assessing their progress (theme 3). PHNs established trusting relationships with mothers.PHNs served as coordinators in resolving problems and provided ongoing support in cooperation with medical institutions and related organizations (theme 4). The PHNs carefully coordinated consultations and encouraged mothers to consult psychiatrists if appropriate. Conclusion　Although PHNs provided attentive care to mothers requiring assistance, difficulties arise in accurately diagnosing postpartum depression and connecting mothers to psychiatric services. Guidelines that standardize the assessment of and responses to mental health issues are required. It is necessary to organize the problems faced by mothers and develop a system of cooperation among various organizations.

RESUMEN

Objectives　This study aimed to clarify the core values and competencies of public health nurses (PHNs) who contribute to improve health issues in transitioning societies, based on a consensus among PHN-related organizations, including practitioners and education researchers.Methods　A draft defining the core values and competencies of PHNs was developed through five consultation sessions with 20 executives and nominees of organizations in each area of PHN practice, education, and research to collect, categorize, and refine the items. The expert panel comprised 534 nominees from six PHN-related organizations, and three rounds of Delphi surveys were conducted. The consensus criteria were ≥70% for agreement and ≥80% for firm agreement.Results　In the first round, 272 expert panel nominees (50.9%) responded, and 217 responded in all rounds. The draft was revised based on the feedback from each round. By round 3, >90% agreed on the core value and competency frameworks and definitions.Conclusion　The Delphi survey revealed the three core value frameworks and definitions of "social justice in health," "human rights and autonomy," and "health and safety" and eight core competencies of "professional autonomy and responsibility," "scientific research and use of information science and technology," "population-based assessment and analysis," "practices for health enhancement and prevention," "building systems to improve public health," "management of healthy community development," "person/community-centered collaboration and cooperation," and "communication for consensus and solutions," with a firm agreement. Eventually, these frameworks would be the bases for creating national standards of practice, education, and research to satisfy the consensus levels of PHNs and PHN-related organizations.

RESUMEN

Objective　We conducted an ecological analysis of the structures and processes of municipalities implementing countermeasure-type colorectal cancer screening services, which are associated with high mortality and morbidity rates. We analyzed the populations' demographic characteristics, number of public health nurses (PHNs), and human base for such services. The process was evaluated using the screening uptake rates for countermeasure-type cancer screening and detection indices.Methods　The data included municipal population figures, areas, and national health insurance enrolments, all sourced from a government statistics portal (e-Stat). We obtained the number of PHNs per 100,000 population from PHN activity area surveys, information on municipal colorectal cancer screening from public health centers (PHCs) and health promotion project reports, and cancer detection indices from the National Cancer Registry data. The analysis covered 1,234 municipalities with populations of ≥10,000 and ≥50,000, categorized into three groups based on the presence of PHCs. The internal structures were compared using multiple regression analysis.Results　The number of PHNs per 100,000 population was categorized as follows; <50,000 population group (42.9), ≥50,000 population group (24.3), and PHC-present city group (16.4).Among these groups, the mass and individual screening rates were 96.2% and 47.7%, 69.1% and 91.5%, and 83.7% and 69.9%, respectively. The average uptake rates of countermeasure-type screenings and detailed examinations were 10.6-13.7% and 68.4-75.3%, respectively. In both cases, the <50,000 population and PHC-present city groups exhibited high and low values, respectively. However, the proportion of patients with "early cancer" detection was approximately 42% in all groups.Multiple regression analysis, using the countermeasure-type screening uptake rate and colorectal cancer detection indices as dependent variables, revealed that in the <50,000 population group, in which mass screening was prevalent, the number of PHNs was significantly positively correlated with the countermeasure-type screening uptake rate and proportion of "new cancers" detected by screening.Contrastingly, the PHC-present city group showed no correlation between the number of PHNs and countermeasure-type screening uptake rate, but a highly detailed examination uptake rate was significantly positively correlated with the proportion of "early cancer" detection.Conclusion　In municipalities without PHCs, countermeasure-type screening uptake rates, particularly mass screening rates, were positively correlated with the number of PHNs and cancer detection indices. In cities with PHCs, in which individual screening was prevalent, the detailed examination uptake rate through countermeasure-type screening was correlated with detection indices.

RESUMEN

BACKGROUND: Research dissemination is essential to accelerate the translating of evidence into practice. Little is known about dissemination among Chinese public health researchers. This study aimed to explore the understanding and practices of disseminating research findings and to identify barriers and facilitators that influence dissemination activities to non-research audiences. METHODS: This study deployed an exploratory qualitative design with purposive and snowball sampling. One focus group with 5 participants and 12 in-depth interviews were conducted with participants working in diverse fields from universities (n = 10), the National Chinese Center for Disease Control and Prevention (n = 4), the Chinese National Cancer Center (n = 1), the Chinese National Center for Cardiovascular Disease (n = 1), and China office of a global research institute (n = 1) from May to December 2021 to reach saturation. Data were initially analyzed using inductive thematic analysis. The designing for dissemination (D4D) logic model was then used to organize themes and subthemes. Two coders independently coded all transcripts and discussed disparities to reach a consensus. RESULTS: Out of 17 participants, 12 misunderstood the concept of dissemination; 14 had disseminated to non-research audiences: 10 to the public, 10 to practitioners, and 9 to policymakers. We identified multiple barriers to dissemination to non-research audiences across four phases of the D4D logic model, including low priority of dissemination, limited application of D4D strategies, insufficient support from the research organizations, practice settings, and health systems, and overemphasis on academic publications. CONCLUSIONS: There was a lack of understanding and experience of dissemination, indicating a lack of emphasis on active dissemination in China. We provide implications for raising awareness, building capacity, facilitating multidisciplinary collaboration, providing incentives and infrastructure, changing climate and culture, establishing communication and executive networks, and accelerating systematic shifts in impact focus.

RESUMEN

BACKGROUND: Physical, mental and social components of well-being are known to be important to health. However, research on well-being often focuses on physical and mental well-being with little attention paid to social well-being. This research aims to develop and preliminarily validate the South Wales Social Well-being Scale (SWSWBS) to measure social well-being. METHODS: A non-experimental and cross-sectional design was applied with two phases: scale development and preliminary validation. Initially, 24 items were drawn from a Group Concept Mapping study exploring the concept of social well-being. These items were reviewed and reduced to 14 for preliminary validation among 103 university students and staff in health and social care disciplines. Construct validity (exploratory factor analysis and convergent validity) were tested. Reliability was demonstrated by internal consistency. Floor and ceiling effects were also evaluated. RESULTS: A 3-factor structure was identified and explored, which highlight the most important features of the social world a person inhabits: "Safe and inclusive interaction with others" (6 items), "Learning, helping, and feeling useful" (4 items), and "Security, worthwhile activities, family and friends" (4 items). The SWSWBS was correlated to the Warwick Edinburgh Mental Well-being Scale and the Four measures of Personal Well-being Scale to some extent. The Cronbach alpha coefficient was 0.85 for the sum score and 0.83-0.86 for individual items. The item-total correlation coefficients ranged between 0.08 and 0.65. The split half reliability coefficient was 0.78. There is absence of a floor effect, but most items had a ceiling effect. CONCLUSIONS: Preliminary validation of the SWSWBS shows the scale has satisfactory psychometric properties with good validity, reliability, and reasonable variability. This study needs to be replicated with larger and representative populations to explore how the scale can be used alongside the Warwick Edinburgh Mental Well-being Scale to capture a holistic/multi-dimensional understanding of well-being.

RESUMEN

BACKGROUND: Celiac disease (CD) is underdiagnosed and associated with diagnostic delays. This has long-term consequences for the health and well-being of people living with the condition. Little is known about the qualitative configurations of the assessment processes of people living with CD. METHODS: Using a thematic network analysis of 24 in-depth interviews, this study explored the experiences of people living with CD related to their assessment processes leading to being diagnosed. RESULTS: A significant diagnostic delay (up to 26 years) was evident in many interviews. Factors contributing to diagnostic delay included limited knowledge about CD among general practitioners (GP) and in the general population, categorisations of symptoms as 'typical' or 'atypical' and psychosomatic explanations of symptoms. Diagnostic delay resulted in (1) decreased psychological well-being due to severe symptoms, changes in self-perception and self-blame; (2) decreased physiological well-being due to comorbidities; and (3) mistrust in the healthcare system, leading to an increase in informants' responsibility for expediting their assessment processes. This suggested the presence of a neoliberal tendency because informants felt they were primarily responsible for their assessment processes. CONCLUSIONS: We encourage the implementation of initiatives to increase awareness of CD among GPs as well as more consistent and frequent use of the screening guideline due to variations in its clinical presentation. Increased awareness and consistency could reduce variations in assessment processes given GPs' varying knowledge about the condition.

RESUMEN

INTRODUCTION: As countries adapted their disaster responses to the COVID-19 pandemic, South Africa responded with an alert-level risk approach based on epidemiological principles that impacted all societal levels. We explored the everyday experiences of people in Cape Town whose basic needs were met and who could report on the realities of the COVID-19 pandemic control. Gaining insight into their perspectives contributes to knowledge that can inform policies and practices for managing future public health crises. METHODS: Community-Based Participatory Research principles guided the design and a series of facilitated dialogues with 18 research participants. The thematic analysis was deepened through two colloquiums with members of an overarching research consortium and a participant reflection workshop. FINDINGS: The pandemic impacted individuals, their interpersonal relationships, workplaces and communities, leading to societal processes such as stigma, virtue signalling and the subversion of mandates. The public health response had mixed reactions, with useful information about preventive measures being diluted by COVID-19 denialism and fake news. Health and other authorities were frequently perceived as out of touch with, and unresponsive to, the everyday realities of local communities. CONCLUSIONS: Our study demonstrates the connectedness of people and the need to maintain and re-establish severed connections. A holistic approach to health care and promotion from social determinants of health and a community-engaged perspective may significantly increase the outcomes of public health responses. PARTICIPANT AND PUBLIC CONTRIBUTION: People with everyday experience of the COVID-19 pandemic-including community members, healthcare workers, case managers, carers and researchers-collaborated on the study design, interview schedule, data interpretation, analysis and refinement of this article.

RESUMEN

BACKGROUND: Public health dietitians navigate complex professional landscapes amid dwindling resources, organisational disruptions and limited advancement opportunities. Cultivating systems thinking and structural empowerment competencies may enable this workforce to address multifaceted public health challenges more effectively. This study explored the extent to which public health dietitians apply systems thinking and perceive access to structural empowerment and the relationship between these constructs. METHODS: A quantitative online survey incorporating the systems thinking scale (STS) and conditions for work effectiveness questionnaire-II (CWEQ-II) was conducted among US public health dietitians who worked in governmental public health. Data were collected from September 2022 to October 2022. Descriptive and inferential statistical analyses were conducted. RESULTS: Among 216 respondents, 98% demonstrated moderate-to-high systems thinking competency (mean STS score = 60.3 ± 8.74, range 28-78). Over 88% reported moderate-to-high perceived structural empowerment (mean CWEQ-II score = 18.3 ± 0.96, range 8-29). Higher systems thinking scores were associated with greater decision-making authority (p = 0.01) but not budget oversight. Higher structural empowerment scores correlated with increased job responsibilities and decision-making authority (p < 0.001). A significant positive correlation existed between systems thinking and structural empowerment (r = 0.24, p < 0.001). Public health dietitians exhibited substantial systems thinking capabilities and perceived access to organisational power structures. CONCLUSIONS: This study offers baseline understanding of systems thinking and structural empowerment among public health dietitians. The positive interplay between these constructs underscores their potential to drive systems-level change and influence population health outcomes. Integrating systems thinking and structural empowerment into dietetic education and professional development may enhance the workforce's preparedness for navigating complexities.

RESUMEN

BACKGROUND: The health visiting service in UK promotes the health and wellbeing of families with young children and comprises a universal offer (three mandated contacts between birth and 12 months) and additional contacts based on need. We aimed to understand how the level of health visiting support received varies by family characteristics. METHODS: Using the Community Services Data Set linked to Hospital Episode Statistics, we identified 52 555 children in 10 local authorities with complete health visiting data for 12 months between April 2016 and March 2020. We analysed variation in health visiting contacts by deprivation, child ethnicity, maternal age, adversity and previous live births. RESULTS: 41 340/52 555 children (79%) received the universal service; 63% received ≥1 additional contact and 25% received ≥3 additional contacts. The likelihood of receiving ≥3 additional contacts was greatest for children whose mothers had a history of hospital admissions relating to mental health, violence, self-harm or substance misuse (adjusted relative risk = 1.55, 95% confidence interval 1.26-1.92). CONCLUSIONS: Most families received health visiting support in addition to the universal service. Policymakers and commissioners should consider how health visiting services can be expanded or targeted more effectively to ensure all families receive the support they need.

RESUMEN

Leishmania, endemic in nearly half the world's countries, continues to pose significant diagnostic challenges. Our systematic review sought to analyse problems in diagnosis especially in low- to middle-income countries. The average time from symptom onset to diagnosis was 4.5 years. While microscopic detection often failed, polymerase chain reaction showed high sensitivity. Clinical presentations varied significantly, highlighting the complexity of diagnosing leishmaniasis, especially in patients with prolonged disease in non-endemic areas.

RESUMEN

BACKGROUND: Identifying symptom clusters in Long COVID is necessary for developing effective therapies for this diverse condition and improving the quality of life of those affected by this heterogeneous condition. In this study, we aimed to identify and compare symptom clusters at 9 and 12 months after a SARS-CoV-2 positive test and describe each cluster regarding factors at infection. METHODS: This is a cross-sectional study with individuals randomly selected from the Portuguese National System of Epidemiological Surveillance (SINAVE) database. Individuals who had a positive RT-PCR SARS-CoV-2 test in August 2022 were contacted to participate in a telephonic interview approximately 9 and 12 months after the test. A hierarchical clustering analysis was performed, using Euclidean distance and Ward's linkage. Clustering was performed in the 35 symptoms reported 9 and 12 months after the SARS-CoV-2 positive test and characterised considering age, sex, pre-existing health conditions and symptoms at time of SARS-CoV-2 infection. RESULTS: 552 individuals were included at 9 months and 458 at 12 months. The median age was 52 years (IQR: 40-64 years) and 59% were female. Hypertension and high cholesterol were the most frequently reported pre-existing health conditions. Memory loss, fatigue or weakness and joint pain were the most frequent symptoms reported 9 and 12 months after the positive test. Four clusters were identified at both times: no or minor symptoms; multi-symptoms; joint pain; and neurocognitive-related symptoms. Clusters remained similar in both times, but, within the neurocognitive cluster, memory loss and concentration issues increased in frequency at 12 months. Multi-symptoms cluster had older people, more females and more pre-existing health conditions at 9 months. However, at 12 months, older people and those with more pre-existing health conditions were in joint pain cluster. CONCLUSIONS: Our results suggest that Long COVID is not the same for everyone. In our study, clusters remained similar at 9 and 12 months, except for a slight variation in the frequency of symptoms that composed each cluster. Understanding Long COVID clusters might help identify treatments for this condition. However, further validation of the observed clusters and analysis of its risk factors is needed.

RESUMEN

INTRODUCTION: It has been well established that grip strength measurements can be useful as a benchmark for comparing the efficacy of different treatment modalities as well as an aid in the assessment of the progress of disease and rehabilitation. Grip strength has also been shown to be a representative marker for sociodemographic factors. METHODS: Participants were selected from five different regions in a cross-sectional manner from the streets of Trinidad and Tobago, and a Jamar hand dynamometer was used to assess the metrics of hand grip, palmar grip, tip pinch, and key pinch across both hands. Data was analyzed comparing right and left as well as dominant and non-dominant hands, and participants were classified by occupation. RESULTS: We enrolled 1233 participants in this study, of which the majority were female (54.5%). 90% of participants were right-hand dominant. The mean hand strength of the dominant hand was significantly greater than the non-dominant for all four strengths assessed. Participants of Afro-Trinbagonian descent were shown to have the highest mean values overall. We found no significant relationship between occupational intensity and mean grip strengths. For the male population, it was found that height, age, and BMI were all significant predictors of hand strength. This was notably only so for a minority of the female population tested. CONCLUSION: This study serves to provide the normative data for the adult healthy Trinbagonian population. Further research to determine better predicative variables specific to the female population is needed.

RESUMEN

Influenza B virus (IBV) stands as a paradox, often overshadowed by its more notorious counterpart, influenza A virus (IAV). Yet, it remains a captivating and elusive subject of scientific inquiry. Influenza B is important because it causes seasonal flu outbreaks that can lead to severe respiratory illnesses, including bronchitis, pneumonia, and exacerbations of chronic conditions like asthma. Limitations in the influenza B virus's epidemiological, immunological, and etiological evolution must be addressed promptly. This comprehensive review covers evolutionary epidemiology and pathogenesis, host-virus interactions, viral isolation and propagation, advanced molecular detection assays, vaccine composition and no animal reservoir for influenza B virus. Complex viral etiology begins with intranasal transmission of influenza B virus with the release of a segmented RNA genome that attacks host cell machinery for transcription and translation within the nucleus and the release of viral progeny. Influenza B virus prevalence in domesticated and wild canines, sea mammals, and birds is frequent, yet there is no zoonosis. The periodic circulation of influenza B virus indicates a 1-3-year cycle for monophyletic strain replacement within the Victoria strain due to frequent antigenic drift in the HA near the receptor-binding site (RBS), while the antigenic stability of Yamagata viruses portrays a more conservative evolutionary pattern. Additionally, this article outlines contemporary antiviral strategies, including pharmacological interventions and vaccination efforts. This article serves as a resource for researchers, healthcare professionals, and anyone interested in the mysterious nature of the influenza B virus. It provides valuable insights and knowledge essential for comprehending and effectively countering this viral foe, which continues to pose a significant public health threat.

RESUMEN

Introduction: Ethiopia has made remarkable progress in expanding access to and provision of comprehensive abortion care. However, complications due to unsafe abortion persist. As efforts to increase quality of comprehensive abortion care continue, evaluating service quality is critical. Although "women-centered" abortion care is a central component of Ethiopia's technical guidelines for safe abortion, research has mostly focused on access to care, availability of services, and meeting clinical criteria, rather than examining service quality from abortion clients' perspectives. This study assesses the quality of comprehensive abortion care (CAC) in public health facilities, from clients' perspectives, in four regions of Ethiopia to examine how person-centered care differs based on facility and service characteristics. Methods: We conducted 1,870 client exit surveys in 2018 using structured questionnaires with women who received induced abortion or postabortion care services from 76 public health facilities across four regions: Tigray, Amhara, Oromia, and Southern Nations, Nationalities, and People's. We operationalized person-centered care by mapping 30 indicators of quality to five of the six domains in the Person-Centered Care Framework for Reproductive Health Equity developed by Sudhinaraset and colleagues (2017): dignity & respect; autonomy; communication & supportive care; trust, privacy, and confidentiality; and health facility environment. We calculated descriptive, bivariate, and multivariable statistics to examine associations between service characteristics and person-centered care. Results: CAC clients reported high levels of person-centered care, with exceptionally positive experiences for outcomes in the dignity and respect and trust, privacy, and confidentiality domains. However, there was notable room for improving client experiences across three domains: autonomy, communication and supportive care, and health facility environment. Client-reported quality outcomes differed significantly by diagnosis (induced or postabortion care), region, health facility type, and procedure type. Clients in Amhara, clients at tertiary and primary hospitals, and clients who received postabortion care reported lower levels of person-centered care. Discussion: The positive experiences reported by comprehensive abortion care clients bolster evidence of the impact of the Ethiopian government's strategy to increase abortion access in the public health sector. However, notable disparities exist for key subgroups, particularly those seeking postabortion care and people visiting tertiary and primary hospitals. Quality improvement efforts should concentrate on improving abortion clients' autonomy, communication and supportive care, and the health facility environment. The Ethiopian Ministry of Health and its partners must dedicate resources to improve postabortion care quality, integration of reproductive health services within CAC, and pain management for MA clients as vital interventions.
