Health Literacy Concepts, Themes, and Research Trends Globally and in Latin America and the Caribbean: A Bibliometric Review.

(1) Background: Health literacy (HL) debates have increased significantly in the last two decades. HL concepts/themes and models have achieved substantial development in the US and Europe. Although there have been some efforts to develop HL in Latin America and the Caribbean (LAC), these seem to be few and scattered. This paper reviews and discusses developments of HL concepts and themes globally and in LAC over the last two decades. (2) Purpose: This study aimed to identify the prevalent health literacy concepts/themes deployed globally and in LAC as reported in academic journals from 2005 to 2022. We looked into which fields of knowledge have been informing HL research over the last decades. (3) Methods: We conducted a structured search on the Web of Science (WoS), Scopus, PubMed, and SciELO databases to extract the textual data for bibliometric analysis. We analyzed the textual data with VOSviewer and Biblioshiny to better understand health literacy themes and strands currently being researched in the LAC region. We conducted the searches in two periods: the first in May 2023 and the second in October 2023. (4) Results: The bibliometric study highlighted five WoS categories informing most HL global studies: (i) public environmental occupational health; (ii) environmental sciences; (iii) health policy services; (iv) health care science services; and (v) communication. The two predominant categories in LAC are public environmental occupation health and health policy services. Journals hosting HL publications come from these WoS categories. Themes in HL publications can be organized into four thematic clusters: (i) analytical (research designs, analytic techniques, and criteria for examining HL data); (ii) psychometric (measurement properties of data collection tools); (iii) pragmatic (practical issues related to implementing HL programs); and (iv) well-being (effectiveness of HL programs on mental health and illness treatment). (5) Conclusions: There is expanding interest in health literacy among scholars. The number of publications has increased substantially, particularly over the last five years. These are dominated by the Global North. The metrics show that LAC and Africa are trailing in publications. There is an emerging focus on adult literacy, functional/low health literacy, and their effect on improving capabilities, comprehension, and communication regarding health-related topics.

Increased quality of life in patients with breakthrough cancer pain after individualized therapy: the CAVIDIOM study.

Aim: To evaluate the quality of life (QoL) in patients with breakthrough cancer pain (BTcP) in Spanish medical oncology departments. Patients & methods: In a prospective, observational, multicenter study, we assessed QoL using the EQ-5D-5L instrument at baseline and after 15 and 30 days of individualized BTcP therapy, as well as BTcP characteristics and treatment. Results: Patients (n = 118) were mainly women, over 64 years old and with advanced cancer. QoL improved at 15 (p = 0.013) and 30 days (p = 0.011) versus baseline. Individualized BTcP therapy consisted mostly of rapid-onset opioids (transmucosal fentanyl at doses of 67-800 µg) according to the physician evaluation. BTcP improved, including statistically significant reductions in intensity, duration, number of episodes in the last 24 h and time to onset of BTcP relief. Conclusion: QoL increased after individualized pain therapy in patients with advanced cancer and BTcP in medical oncology departments.

Cancer patients can experience flares of pain, called breakthrough pain (BTcP), despite treatment with painkillers. Although BTcP can be excruciating, its intensity and other characteristics depend on several factors, including its treatment. However, even if treated, BTcP can impair quality of life for cancer patients. We assessed quality of life in 118 patients with advanced cancer and BTcP treated in 13 medical oncology departments across Spain. We treated BTcP with individualized therapy, taking into account both pain-related and patient-related factors. We also measured quality of life using a specific, widely-used questionnaire at the study visits: at onset of individualized pain therapy and after 3, 15 and 30 days' treatment. At each visit, flare-up pain therapy was adjusted or maintained as necessary. Throughout the study, quality of life and sleep quality improved for all participants. Furthermore, there was a greater reduction in intensity, duration and frequency of BTcP. The most common treatments for flare-ups were low doses of rapid-onset opioids (fentanyl given by sublingual, buccal or nasal administration), which were much better tolerated than high-dose opioids. Overall, the study showed that quality of life in patients with advanced cancer and BTcP increased after individualized pain therapy, mainly with low doses of rapid-onset opioids.

Daily food planning for families under Covid-19: combining analytic hierarchy processes and linear optimisation.

In many households, preparation of food in normal times proves to be problematic, particularly when parents endeavour to keep their children on a balanced diet. The COVID-19 pandemic has further exacerbated this problem imposing the requirement of social distancing, which led to disruptions in the food supply chain and multiplication of responsibilities faced by families with children. The present study revisits the standard "Diet Problem" to address these challenges and to develop a participatory approach to provide a diversified weekly meal plan that is easy and fun but simultaneously complies with the unique requirements of each participant. This is done by providing a novel framework, which combines linear optimisation with the Parsimonious Analytic Hierarchy Process, a method for individual choices. This novel approach to participatory modelling is tested within two young family settings in Brazil. The model produced through this contemporary framework provides a weekly menu that best meets expectations of the members of a young family in the context of the COVID-19 pandemic.

Planetary Health and Health Education in Brazil: Towards Better Trained Future Health Professionals.

Brazil is Latin America's largest country and has a strong economy, but it is also characterised by many inequalities. These are very conspicuous in the health sector, particularly in health education, which is expected to modernise according to the planetary health (PH) perspective. This paper describes the health education scenario in Brazil and undertakes an analysis of the postgraduate health programmes and policies in place, identifying the extent to which these support the cause of PH. To achieve this goal, this paper deploys a bibliometric analysis to gain a better understanding of the research streams related to higher education and PH. In addition, it presents and discusses selected case studies in the field and cross-checks documents from the Brazilian Ministry of Education against five domains of PH in education. The results indicate that despite some progress to date and the fact that some programmes are in place, there is a perceived need for policies and efforts from education organisations towards connecting PH principles in the education of current and future health professionals.

Derechos del concebido

La fecundación consiste en la fusión de los gametos masculino y femenino en el tercio externo de la trompa uterina para constituir el cigoto, que inicia su división celular, viaja al útero, se implanta como blastocito en el endometrio a los siete días y comienzan los procesos de embriogénesis y morfogénesis. Concepción es la acción o efecto de quedar embarazada una mujer. En el tema de los derechos establecidos al concebido, el inicio de la vida humana plantea amplia discusión entre las definiciones que plantea la ciencia frente a las de grupos de la sociedad civil. No siendo el cigoto una persona humana, de acuerdo con la Corte Interamericana de Derechos Humanos (CIDH) y otros no sería sujeto de los derechos establecidos para la persona, los cuales estarían íntimamente relacionados a los derechos de la mujer embarazada. La concepción ocurriría cuando el embrión se implanta en el útero y no aplicaría el artículo 4 de la CIDH. La doctrina, la legislación y la jurisprudencia peruana establecen amplia tutela jurídica a favor del concebido e instauran el inicio de la vida a partir de la fecundación. La Sentencia de la CIDH para el caso Artavia Murillo contra Costa Rica introduce la figura española del preembrión, al cual no se le otorga tutela jurídica hasta los 14 días, momento en que la ciencia médica establece la implantación del embrión en el endometrio materno. Para consideraciones éticas actuales, el embarazo humano empieza con la implantación del blastocisto en el endometrio y no existe sustento para aceptar el derecho del concebido desde el momento de la fecundación como si fuera una persona. Empero se señala que la vida humana posee una continuidad ininterrumpida desde su concepción hasta su fin natural, la muerte. El cigoto es vida que se inicia con dotación genética propia diferente a la de sus progenitores. El embrión preimplantatorio solo podrá originar un ser humano que se gesta y desarrolla dentro del cuerpo de otra persona, con propia dinámica vital.

Fertilization consists of the fusion of the male and female gametes in the outer third of the uterine tube to form the zygote, which begins its cell division, travels to the uterus, implants as a blastocyst in the endometrium after seven days and begins the processes of embryogenesis and morphogenesis. Conception is the action or effect of a woman becoming pregnant. About the rights established for the conceived, the beginning of human life raises a wide discussion between the definitions proposed by science and those of civil society groups. Not being the zygote a human person, according to the Inter-American Court of Human Rights (IACHR) and others, it would not be subject to the rights established for the person, which would be closely related to the rights of the pregnant woman. Conception would occur when the embryo implants in the uterus and Article 4 of the IACHR would not apply. Peruvian doctrine, legislation and jurisprudence establish broad legal protection in favor of the conceived and indicate the beginning of life from the moment of fertilization. The Judgment of the IACHR in the case of Artavia Murillo v. Costa Rica introduces the Spanish figure of the pre-embryo, which is not granted legal protection until 14 days, when medical science establishes the implantation of the embryo in the maternal endometrium. For current ethical considerations, human pregnancy begins with the implantation of the blastocyst in the endometrium and there is no basis for accepting the right of the conceived from the moment of fertilization as if it were a person. However, it is pointed out that human life has an uninterrupted continuity from conception to its natural end, death. The zygote is life that begins with its own genetic endowment different from that of its progenitors. The preimplantation embryo can only give rise to a human being that is gestated and develops within the body of another person, with its own vital dynamics.

Importance of Evaluating Cardiovascular Risk and Hepatic Fibrosis in Patients With Newly Diagnosed Nonalcoholic Fatty Liver Disease.

Nonalcoholic fatty liver disease (NAFLD) is a well-recognized health problem, with an estimated worldwide prevalence of 25%.1 It is associated with metabolic syndrome (MetSx) and complications such as cirrhosis and hepatocellular carcinoma. However, the main cause of death in patients with NAFLD is derived from cardiovascular disease, and outcome seems to be determined by the degree of hepatic fibrosis.2 The prevalence of NAFLD and associated cardiovascular risk factors in asymptomatic patients in Mexico are poorly documented, despite having one of the highest rates of obesity and metabolic syndrome worldwide.3.

Campylobacter ornithocola sp. nov., a novel member of the Campylobacter lari group isolated from wild bird faecal samples.

During a study on the prevalence and diversity of campylobacteria in wild birds faecal samples from the city of Valdivia (southern Chile) 17 Gram-stain-negative, curved-rod-shaped isolates, were initially identified as Campylobacter lari by PCR-RFLP. Further identification by 16S rRNA sequence analysis revealed that they formed a distinct group in the genus Campylobacter. This unique position was confirmed by the results of analysis of rpoB, atpA and cpn60 gene sequences. The average nucleotide identity between the representative strain WBE38T and the type strain of the most closely related taxon C. larisubsp.concheus (LMG 11760) was 90.8 %. The oxidase and urease activity of the novel isolates enabled them to be phenotypically differentiated from species of the genus Campylobacter with validly published names. Therefore, on the basis of phenotypic, genetic and genomic characterizations, the results of this study clearly indicate that these strains represent a novel species within the genus Campylobacter, for which the name Campylobacter ornithocola sp. nov. is proposed, with the type strain WBE38T (=CECT 9147T=LMG 29815T).

Histiocitosis medular maligna. Reporte de un caso / Malignant histiocytosis core. A case report

En 1939, Scott y Robb-Smith describen cuatro pacientes propios y seis provenientes de la literatura, con una enfermedad caracterizada por fiebre, agotamiento y linfoadenopatía generalizada, asociada con espleno y hepatomegalia y, en los estadíos finales, ictericia, púrpura y anemia con profunda leucopenia. Cerca de 100 casos se han registrado en la literatura con el nombre “Reticulosis Medular Histiocítica” y una variedad de términos. En 1966 Rappaport introduce el término de “Histiocitosis Maligna”, y describe éste desorden caracterizado por una progresión sistémica y proliferación invasiva de histiocitos atípicos.

In 1939, Scott and Robb –Smith described four pacients of their own and six from the literatura with a disease characterized lymphadenopathy associated with splenic and hepatic enlargement and in the final stages jaundice, purpura and anemia. About 100 cases have been reported in the literature under the name “Histiocytic medullary reticulosis” and a variety of terms. In 1966 Rappaport introduced the term “malignant histiocytosis”, to describe this disorder characterized by a systemic progressive and invasive proliferation of morphologically atipic histiocytes.
