Antioxidants in Photoaging: From Molecular Insights to Clinical Applications.

Photoaging (PA) is considered a silent disease affecting millions of people globally and is defined as skin damage due to prolonged exposure to ultraviolet radiation (UVR) from the sun. Physiologically, the skin is in a state of renewal and synthesis of components of the extracellular matrix (ECM). However, exposure to UVR affects the production of the ECM, and the functioning and response of skin cells to UVR begins to change, thus expressing clinical and phenotypic characteristics of PA. The primary mechanisms involved in PA are direct damage to the DNA of skin cells, increases in oxidative stress, the activation of cell signaling pathways responsible for the loss of skin integrity, and cytotoxicity. The medical and scientific community has been researching new therapeutic tools that counteract PA, considering that the damage caused by UVR exceeds the antioxidant defense mechanisms of the skin. Thus, in recent years, certain nutraceuticals and phytochemicals have been found to exhibit potential antioxidant and photoprotective effects. Therefore, the main objective of this review is to elucidate the molecular bases of PA and the latest pharmaceutical industry findings on antioxidant treatment against the progression of PA.

Weight Regain after Metabolic Surgery: Beyond the Surgical Failure.

Patients undergoing metabolic surgery have factors ranging from anatomo-surgical, endocrine metabolic, eating patterns and physical activity, mental health and psychological factors. Some of the latter can explain the possible pathophysiological neuroendocrine, metabolic, and adaptive mechanisms that cause the high prevalence of weight regain in postbariatric patients. Even metabolic surgery has proven to be effective in reducing excess weight in patients with obesity; some of them regain weight after this intervention. In this vein, several studies have been conducted to search factors and mechanisms involved in weight regain, to stablish strategies to manage this complication by combining metabolic surgery with either lifestyle changes, behavioral therapies, pharmacotherapy, endoscopic interventions, or finally, surgical revision. The aim of this revision is to describe certain aspects and mechanisms behind weight regain after metabolic surgery, along with preventive and therapeutic strategies for this complication.

Neonatal mortality in countries of the Americas, 2000–2020: trends, inequalities, and target-setting / Mortalidad neonatal en los países de la Región de las Américas, 2000-2020: tendencias, desigualdades y establecimiento de metas / Mortalidade neonatal nos países das Américas, 2000-2020: tendências, desigualdades e definição de metas

[ABSTRACT]. Objective. To analyze temporal trends and inequalities in neonatal mortality between 2000 and 2020, and to set neonatal mortality targets for 2025 and 2030 in the Americas. Methods. A descriptive ecological study was conducted using 33 countries of the Americas as units of anal- ysis. Both the percentage change and average annual percentage change in neonatal mortality rates were estimated. Measurements of absolute and relative inequality based on adjusted regression models were used to assess cross-country social inequalities in neonatal mortality. Targets to reduce neonatal mortality and cross-country inequalities were set for 2025 and 2030. Results. The estimated regional neonatal mortality rate was 12.0 per 1 000 live births in 2000–2004 and 7.4 per 1 000 live births in 2020, representing a percentage change of –38.3% and an average annual per- centage change of –2.7%. National average annual percentage changes in neonatal mortality rates between 2000–2004 and 2020 ranged from –5.5 to 1.9 and were mostly negative. The estimated excess neonatal mor- tality in the 20% most socially disadvantaged countries, compared with the 20% least socially disadvantaged countries, was 17.1 and 9.8 deaths per 1 000 live births in 2000–2004 and 2020, respectively. Based on an extrapolation of recent trends, the regional neonatal mortality rate is projected to reach 7.0 and 6.6 neonatal deaths per 1 000 live births by 2025 and 2030, respectively. Conclusions. National and regional health authorities need to strengthen their efforts to reduce persistent social inequalities in neonatal mortality both within and between countries.

Description of maternal and neonatal adverse events in pregnant people immunised with COVID-19 vaccines during pregnancy in the CLAP NETWORK of sentinel sites. Nested case-control analysis of the immunization-associated risk: A study protocol.

INTRODUCTION: COVID-19 is associated with higher morbimortality in pregnant people compared with non-pregnant people. At present, the benefits of maternal immunisation are considered to outweigh the risks, and therefore, vaccination is recommended during pregnancy. However, additional information is needed on the safety of the vaccines in this population. METHODS AND ANALYSIS: This a retrospective cohort nested case-control study in pregnant people who attended maternity hospitals from eight Latin American and Caribbean countries. A perinatal electronic clinical history database with neonatal and obstetric information will be used. The proportion of pregnant people immunised with COVID-19 vaccines of the following maternal and neonatal events will be described: preterm infant, small for gestational age, low birth weight, stillbirth, neonatal death, congenital malformations, maternal near miss and maternal death. Moreover, the risk of prematurity, small for gestational age and low birth weight associated with exposure to COVID-19 vaccines will be estimated. Each case will be matched with two groups of three randomly selected controls. Controls will be matched by hospital and mother's age (±3 years) with an additional matching by delivery date and conception time in the first and second control groups, respectively. The estimated required sample size for the main analysis (exposure to any vaccine) concerning 'non-use' is at least 1009 cases (3027 controls) to detect an increased probability of vaccine-associated event risk of 30% and at least 650 cases (1950 controls) to detect 30% protection. Sensitivity and secondary analyses considering country, type of vaccine, exposure windows and completeness of immunisation will be reported. ETHICS: The study protocol was reviewed by the Ethical Review Committee on Research of the Pan American Health Organization. Patient informed consent was waived due to the retrospective design and the utilisation of anonymised data (Ref. No: PAHOERC.0546.01). Results will be disseminated in open access journals.

Promotion of structural plasticity in area V2 of visual cortex prevents against object recognition memory deficits in aging and Alzheimer's disease rodents.

JOURNAL/nrgr/04.03/01300535-202408000-00038/figure1/v/2023-12-16T180322Z/r/image-tiff Memory deficit, which is often associated with aging and many psychiatric, neurological, and neurodegenerative diseases, has been a challenging issue for treatment. Up till now, all potential drug candidates have failed to produce satisfactory effects. Therefore, in the search for a solution, we found that a treatment with the gene corresponding to the RGS14414 protein in visual area V2, a brain area connected with brain circuits of the ventral stream and the medial temporal lobe, which is crucial for object recognition memory (ORM), can induce enhancement of ORM. In this study, we demonstrated that the same treatment with RGS14414 in visual area V2, which is relatively unaffected in neurodegenerative diseases such as Alzheimer's disease, produced long-lasting enhancement of ORM in young animals and prevent ORM deficits in rodent models of aging and Alzheimer's disease. Furthermore, we found that the prevention of memory deficits was mediated through the upregulation of neuronal arborization and spine density, as well as an increase in brain-derived neurotrophic factor (BDNF). A knockdown of BDNF gene in RGS14414-treated aging rats and Alzheimer's disease model mice caused complete loss in the upregulation of neuronal structural plasticity and in the prevention of ORM deficits. These findings suggest that BDNF-mediated neuronal structural plasticity in area V2 is crucial in the prevention of memory deficits in RGS14414-treated rodent models of aging and Alzheimer's disease. Therefore, our findings of RGS14414 gene-mediated activation of neuronal circuits in visual area V2 have therapeutic relevance in the treatment of memory deficits.

Surveillance of severe maternal morbidity and maternal mortality in maternity hospitals of the Latin American and Caribbean network - Red CLAP: study protocol.

The sustained reduction in maternal mortality in America underlines the need to analyse women who survived a complication that could have been fatal if appropriate and timely care had not been taken. Analysis of maternal near-miss (MNM) cases, as well as potentially life-threatening conditions (PLTC), are considered indicators for monitoring the quality of maternal care. The specific objective of this study protocol is to develop a surveillance system for PLTC, MNM and maternal mortality, as primary outcomes, in Latin American and Caribbean maternal healthcare institutions. Secondarily, the study was designed to identify factors associated with these conditions and estimate how often key evidence-based interventions were used for managing severe maternal morbidity. This is a multicenter cross-sectional study with prospective data collection. The target population consists of all women admitted to health centres participating in the network during pregnancy, childbirth, or the postpartum period. Variables describing the sequence of events that may result in a PLTC, MNM or maternal death are recorded. Relevant quality control is carried out to ensure the quality of the database and confidentiality. Centres with approximately 2,500 annual deliveries will be included to achieve a sufficient number of cases for calculation of indicators. The frequency of outcome measures for PLTC, MNM and maternal mortality and their confidence intervals and differences between groups will be calculated using the most appropriate statistical tests. Similar procedures will be performed with variables describing the use of evidence-based practices. Networking creates additional possibilities for global information management and interaction between different research groups. Lessons can be learned and shared, generating scientific knowledge to address relevant health problems throughout the region with provision of efficient data management.

Durvillaea antarctica: A Seaweed for Enhancing Immune and Cardiometabolic Health and Gut Microbiota Composition Modulation.

Durvillaea antarctica is the seaweed that is the most consumed by the Chilean population. It is recognized worldwide for its high nutritional value in protein, vitamins, minerals, and dietary fiber. This is a narrative review in which an extensive search of the literature was performed to establish the immunomodulator, cardiometabolic, and gut microbiota composition modulation effect of Durvillaea antarctica. Several studies have shown the potential of Durvillaea antarctica to function as prebiotics and to positively modulate the gut microbiota, which is related to anti-obesity, anti-inflammatory, anticancer, lipid-lowering, and hypoglycemic effects. The quantity of Bacteroides was negatively correlated with that of inflammatory monocytes and positively correlated with the levels of several gut metabolites. Seaweed-derived polysaccharides modulate the quantity and diversity of beneficial intestinal microbiota, decreasing phenol and p-cresol, which are related to intestinal diseases and the loss of intestinal function. Additionally, a beneficial metabolic effect related to this seaweed was observed, mainly promoting the decrease in the glycemic levels, lower cholesterol levels and cardiovascular risk. Consuming Durvillaea antarctica has a positive impact on the immune system, and its bioactive compounds provide beneficial effects on glycemic control and other metabolic parameters.

Exploring the Relationship between the Gut Microbiota and Ageing: A Possible Age Modulator.

The gut microbiota (GM) has been the subject of intense research in recent years. Therefore, numerous factors affecting its composition have been thoroughly examined, and with them, their function and role in the individual's systems. The gut microbiota's taxonomical composition dramatically impacts older adults' health status. In this regard, it could either extend their life expectancy via the modulation of metabolic processes and the immune system or, in the case of dysbiosis, predispose them to age-related diseases, including bowel inflammatory and musculoskeletal diseases and metabolic and neurological disorders. In general, the microbiome of the elderly tends to present taxonomic and functional changes, which can function as a target to modulate the microbiota and improve the health of this population. The GM of centenarians is unique, with the faculty-promoting metabolic pathways capable of preventing and counteracting the different processes associated with age-related diseases. The molecular mechanisms by which the microbiota can exhibit anti-ageing properties are mainly based on anti-inflammatory and antioxidant actions. This review focuses on analysing the current knowledge of gut microbiota characteristics and modifiers, its relationship with ageing, and the GM-modulating approaches to increase life expectancy.

[Strategies for health services in women, newborns, children, and adolescents during the COVID-19 pandemic in countries of Americas]. / Estrategias de servicios de salud en mujeres, recién nacidos/as, niños/as y adolescentes durante la pandemia de COVID-19 en países de las Américas.

The article analyzes the perceived challenges and strategies implemented in five Latin American and Caribbean countries to ensure continuity of care and access to health services for women, newborns, children, and adolescents during the COVID-19 pandemic. The study corresponds to a quick assessment based on semi-structured interviews with key informants in countries selected by convenience: Colombia, Ecuador, Guatemala, Grenada, and the Dominican Republic. Interviews were conducted with 23 key informants: (a) decision makers at the national and/or subnational level, (b) healthcare professionals, and (c) representatives of civil society organizations; from December 2020 to January 2021. Among the findings, at the beginning of the pandemic, priority was given to the COVID-19 care, with measures to limit the flow of people to health facilities in the countries involved, closing or limiting outpatient visits and restricting care schedule. For women, this affected family planning services and access to contraceptive methods, implying a reduction in prenatal check-ups. As a result of this deinstitutionalization of care, among newborns, a decrease in pediatric check-ups, a decrease in timely immunization and late detection of pathologies or growth problems were reported. Among adolescents, a strong restriction of family planning services, the limitation of other friendly counseling spaces and difficulties in accessing contraceptives were observed.

El artículo analiza los desafíos percibidos y las estrategias implementadas en cinco países de América Latina y el Caribe para garantizar la continuidad de los cuidados y el acceso a servicios de salud de mujeres, recién nacidos/as, niños/as y adolescentes durante la pandemia por COVID-19. El estudio corresponde a una evaluación rápida basada en entrevistas semi-estructuradas a informantes clave de países seleccionados por conveniencia: Colombia, Ecuador, Guatemala, Granada y República Dominicana. Se realizaron entrevistas con 23 informantes clave: (a) referentes de la toma de decisión a nivel nacional y/o subnacional, (b) referentes de servicios de salud, y (c) representantes de organizaciones de la sociedad civil, durante diciembre de 2020 y enero de 2021. Entre los hallazgos, al inicio de la pandemia se priorizó la atención del COVID-19, con medidas para limitar la afluencia de personas a los establecimientos de salud en los países involucrados, procediendo al cierre o limitación de consultas externas y restricción de horarios de atención. Para las mujeres, esto impactó en los servicios de planificación familiar y el acceso a métodos anticonceptivos, e implicó una reducción de los controles prenatales. Por esta desinstitucionalización de la atención, entre recién nacidos/as fue reportada una disminución de los controles pediátricos, una disminución de su vacunación oportuna y una detección tardía de patologías o problemas de crecimiento. Entre adolescentes, se señaló una fuerte restricción de los servicios de planificación familiar, la limitación de otros espacios amigables de consejería y dificultades para acceder a anticonceptivos.

Entre as conclusões encontrou-se que, no início da pandemia, foi dada prioridade à COVID-19, com medidas para limitar o fluxo de pessoas às instalações de saúde nos países envolvidos, fechando ou limitando as consultas ambulatoriais e restringindo o horário de atendimento. Para as mulheres, a medida impactou os serviços de planejamento familiar e o acesso à contracepção, significando uma redução nos check-ups pré-natais. Como resultado desta desinstitucionalização dos cuidados, uma diminuição dos check-ups pediátricos, uma diminuição das vacinações no período correto e uma detecção tardia de patologias ou problemas de crescimento foram relatados entre os/as recém-nascidos/as. Entre os adolescentes, foi observada uma restrição severa dos serviços de planejamento familiar, a limitação de acesso a espaços de aconselhamento amigável e dificuldades de acesso a contraceptivos.

Equity throughout the life course and the evolving role of the Pan American Health Organization / Equidad a lo largo del curso de vida y la evolución del papel de la Organización Panamericana de la Salud / Equidade ao longo da vida e a evolução do papel da Organização Pan-Americana da Saúde

ABSTRACT The objective of this article is to summarize the evolution of the regional commitments of the Pan American Health Organization (PAHO) on health promotion and strategies to improve the health and well-being of women, children, adolescents, and older persons. PAHO regional strategies approved by Member States in the last 20 years are used as the main source of information. The article presents the challenges of making health promotion a public health strategy widely applied in the Region of the Americas and the efforts to renew Member States' collective actions. The article also describes current PAHO efforts to include the positive aspects of health (i.e., well-being, optimal development, and functional ability) and the life course approach as opportunities to advance equity. The article reflects on immunization as a public good and the urgency to address the current challenges as a core element of the regional efforts to transform health systems after more than two years of the COVID-19 pandemic.

Psychosis in Parkinson's Disease: Looking Beyond Dopaminergic Treatments.

BACKGROUND: Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. The symptoms of PD are characterized not only by motor alterations but also by a spectrum of nonmotor symptoms. Some of these are psychiatric manifestations such as sleep disorders; depression; cognitive difficulties that can evolve into dementia; and symptoms of psychosis, which include hallucinations, illusions, and delusions. Parkinson's disease psychosis (PDP) occurs in 18-50% of patients with PD. Treating PDP is challenging because antipsychotic drugs tend to be inefficient or may even worsen the disease's motor symptoms. OBJECTIVE: This review aims to summarize the current understanding of the molecular mechanisms involved in PDP and recent innovative alternatives for its treatment. METHODS: This is a narrative review in which an extensive literature search was performed on the Scopus, EMBASE, PubMed, ISI Web of Science, and Google Scholar databases from inception to August 2021. The terms "Parkinson's disease psychosis", "Parkinson psychosis," "neurodegenerative psychosis", and "dopamine psychosis" were among the keywords used in the search. RESULTS: Recently, views on the etiology of hallucinations and illusions have evolved remarkably. PDP has been cemented as a multifactorial entity dependent on extrinsic and novel intrinsic mechanisms, including genetic factors, neurostructural alterations, functional disruptions, visual processing disturbances, and sleep disorders. Consequently, innovative pharmacological and biological treatments have been proposed. Pimavanserin, a selective 5-HT2A inverse agonist, stands out after its approval to treat PDP-associated hallucinations and illusions. CONCLUSION: Future results from upcoming clinical trials should further characterize the role of this drug in the management of PDP as well as other treatment options with novel mechanisms of action, such as saracatinib, SEP-363856, cannabidiol, electroconvulsive therapy, and transcranial magnetic stimulation.

Exploring the Links between Obesity and Psoriasis: A Comprehensive Review.

Obesity is a major public health issue worldwide since it is associated with the development of chronic comorbidities such as type 2 diabetes, dyslipidemias, atherosclerosis, some cancer forms and skin diseases, including psoriasis. Scientific evidence has indicated that the possible link between obesity and psoriasis may be multifactorial, highlighting dietary habits, lifestyle, certain genetic factors and the microbiome as leading factors in the progress of both pathologies because they are associated with a chronic pro-inflammatory state. Thus, inflammation management in obesity is a plausible target for psoriasis, not only because of the sick adipose tissue secretome profile but also due to the relationship of obesity with the rest of the immune derangements associated with psoriasis initiation and maintenance. Hence, this review will provide a general and molecular overview of the relationship between both pathologies and present recent therapeutic advances in treating this problem.

Endoscopic transsphenoidal endonasal surgery in pituitary adenomas / Cirugía endoscópica vía endonasal transesfenoidal en adenomas de hipófisis

The pituitary adenomas comprise the largest part of pituitary neoplasms, representing between 9 and 12% of primary brain tumors. Currently, the treatment of election is the surgical, the trans-sphenoidal endonasal path has provided a broader panoramic view, being feasible more delicate and safe procedures. The objective of this study was to describe the management of pituitary adenomas by endoscopic surgery trans-sphenoidal endonasal path.

Intracellular Cholesterol Pools Regulate Oncogenic Signaling and Epigenetic Circuitries in Early T-cell Precursor Acute Lymphoblastic Leukemia.

Early T-cell acute lymphoblastic leukemia (ETP-ALL) is an aggressive hematologic malignancy associated with early relapse and poor prognosis that is genetically, immunophenotypically, and transcriptionally distinct from more mature T-cell acute lymphoblastic leukemia (T-ALL) tumors. Here, we leveraged global metabolomic and transcriptomic profiling of primary ETP- and T-ALL leukemia samples to identify specific metabolic circuitries differentially active in this high-risk leukemia group. ETP-ALLs showed increased biosynthesis of phospholipids and sphingolipids and were specifically sensitive to inhibition of 3-hydroxy-3-methylglutaryl-CoA reductase, the rate-limiting enzyme in the mevalonate pathway. Mechanistically, inhibition of cholesterol synthesis inhibited oncogenic AKT1 signaling and suppressed MYC expression via loss of chromatin accessibility at a leukemia stem cell-specific long-range MYC enhancer. In all, these results identify the mevalonate pathway as a druggable novel vulnerability in high-risk ETP-ALL cells and uncover an unanticipated critical role for cholesterol biosynthesis in signal transduction and epigenetic circuitries driving leukemia cell growth and survival. SIGNIFICANCE: Overtly distinct cell metabolic pathways operate in ETP- and T-ALL pointing to specific metabolic vulnerabilities. Inhibition of mevalonate biosynthesis selectively blocks oncogenic AKT-MYC signaling in ETP-ALL and suppresses leukemia cell growth. Ultimately, these results will inform the development of novel tailored and more effective treatments for patients with high-risk ETP-ALL.
