Vitamin D and Sarcopenia in the Senior People: A Review of Mechanisms and Comprehensive Prevention and Treatment Strategies.

This article reviews the mechanisms and prevention strategies associated with vitamin D and sarcopenia in older adults. As a geriatric syndrome, sarcopenia is defined by a notable decline in skeletal muscle mass and strength, which increases the risk of adverse health outcomes such as falls and fractures. Vitamin D, an essential fat-soluble vitamin, is pivotal in skeletal muscle health. It affects muscle function through various mechanisms, including regulating calcium and phosphorus metabolism, promoting muscle protein synthesis, and modulation of muscle cell proliferation and differentiation. A deficiency in vitamin D has been identified as a significant risk factor for the development of sarcopenia in older adults. Many studies have demonstrated that low serum vitamin D levels are significantly associated with an increased risk of sarcopenia. While there is inconsistency in the findings, most studies support the importance of vitamin D in maintaining skeletal muscle health. Vitamin D influences the onset and progression of sarcopenia through various pathways, including the promotion of muscle protein synthesis, the regulation of mitochondrial function, and the modulation of immune and inflammatory responses. Regarding the prevention and treatment of sarcopenia, a combination of nutritional, exercise, and pharmacological interventions is recommended. Further research should be conducted to elucidate the molecular mechanism of vitamin D in sarcopenia, to study genes related to sarcopenia, to perform large-scale clinical trials, to investigate special populations, and to examine the combined application of vitamin D with other nutrients or drugs. A comprehensive investigation of the interconnection between vitamin D and sarcopenia will furnish a novel scientific foundation and productive strategies for preventing and treating sarcopenia. This, in turn, will enhance the senior people's quality of life and health.

Motivation, responsibilities, and experiences of HIV/AIDS counselors in the Volta Region of Ghana: a descriptive phenomenological study.

BACKGROUND: The provision of professional counseling services for persons living with human immunodeficiency virus (PLHIV) is crucial in the prevention and treatment continuum of the disease. However, for counselors of people infected with the human immunodeficiency virus (HIV) leading to acquired immune deficiency syndrome (AIDS) to give their best, their motivations to become counselors and the challenges they face in their line of duty need to be contextually understood and addressed. We ascertained the roles, motivations, and experiences of HIV/AIDS counselors in the Volta Region of Ghana to inform HIV/AIDS counseling decision-making in the region and the country. METHODS: A phenomenological study conducted among sixteen (16) HIV/AIDS counselors from five HIV/AIDS sentinel sites in the Volta region of Ghana, recruited through a purposive sampling approach and interviewed to ascertain their HIV/AIDS counseling-related experiences. The data were thematically analyzed using the Atlas. ti software, and sub-themes supported with verbatim quotes. RESULTS: Five motives for becoming an HIV/AIDS counselor were found. These include being randomly assigned to the unit, developing interest in the job, because of the status of a relative, witnessing bad attitudes of healthcare providers, and seeing HIV- clients lacking knowledge of the condition. The study found that these counselors performed six core roles: providing nutritional counseling, educating clients on HIV, treatment, and medication provision, conducting testing and comprehensive counseling of clients, providing social support to clients, and offering financial support to clients. The experiences these counselors had were boosting clients' health status, counseling clients back to a normal mental state, cooperation from clients, participants gaining knowledge on HIV through counseling, counseling clients to accept their status, and when a client delivered an HIV-negative baby. Their negative experiences included clients denying their HIV status, clients defaulting on their treatment, uncooperative clients, death of clients due to fear of breach of confidentiality, self-stigmatization among clients, and the myths some people hold towards HIV/AIDS. CONCLUSION: By organizing capacity-building training programs for HIV/AIDS counselors in the Volta region and addressing the negative experiences they encounter, they could be empowered to provide effective counseling, curative, and social services to people living with HIV in the region, leading to improved health outcomes.

C-Reactive Protein: An Important Inflammatory Marker of Coronary Atherosclerotic Disease.

Cardiovascular disease (CVD) is the most common cause of death worldwide, with coronary atherosclerotic heart disease (CHD) accounting for the majority of events. Evidence demonstrates that inflammation plays a vital role in the development of CHD. The association between C-reactive protein (CRP), a representative inflammatory biomarker, and atherosclerosis (AS), CHD, and inflammation has attracted attention. Therefore, we conducted an extensive search on PubMed using the aforementioned terms as search criteria and identified a total of 1246 articles published from January 2000 to April 2024. Both review and research-based articles consistently indicate CRP as a risk enhancer for CVD, contributing to the refinement of risk stratification and early identification of apparently healthy at-risk populations. Additionally, CRP reflects disease progression and predicts the prognosis of recurrent cardiovascular events. Anti-inflammatory therapeutic strategies targeting CRP also provide new treatment options for patients. This review focuses on the link between CRP and CHD, highlighting how CRP is involved in the pathological progression of AS and its potential value for clinical applications.

PAHs as environmental pollutants and their neurotoxic effects.

Polycyclic aromatic hydrocarbons (PAHs), which are widely present in incompletely combusted air particulate matter <2.5 µm (PM2.5), tobacco and other organic materials, can enter the human body through various routes and are a class of environmental pollutants with neurotoxic effects. PAHs exposure can lead to abnormal development of the nervous system and neurobehavioral abnormalities in animals, including adverse effects on the nervous system of children and adults, such as a reduced learning ability, intellectual decline, and neural tube defects. After PAHs enter cells of the nervous system, they eventually lead to nervous system damage through mechanisms such as oxidative stress, DNA methylation and demethylation, and mitochondrial autophagy, potentially leading to a series of nervous system diseases, such as Alzheimer's disease. Therefore, preventing and treating neurological diseases caused by PAHs exposure are particularly important. From the perspective of the in vitro and in vivo effects of PAHs exposure, as well as its effects on human neurodevelopment, this paper reviews the toxic mechanisms of action of PAHs and the corresponding prevention and treatment methods to provide a relevant theoretical basis for preventing the neurotoxicity caused by PAHs, thereby reducing the incidence of diseases related to the nervous system and protecting human health.

Gut microbiota regulates gut homeostasis, mucosal immunity and influences immune-related diseases.

The intestinal microbiome constitutes a sophisticated and massive ecosystem pivotal for maintaining gastrointestinal equilibrium and mucosal immunity via diverse pathways. The gut microbiota is continuously reshaped by multiple environmental factors, thereby influencing overall wellbeing or predisposing individuals to disease state. Many observations reveal an altered microbiome composition in individuals with autoimmune conditions, coupled with shifts in metabolic profiles, which has spurred ongoing development of therapeutic interventions targeting the microbiome. This review delineates the microbial consortia of the intestine, their role in sustaining gastrointestinal stability, the association between the microbiome and immune-mediated pathologies, and therapeutic modalities focused on microbiome modulation. We emphasize the entire role of the intestinal microbiome in human health and recommend microbiome modulation as a viable strategy for disease prophylaxis and management. However, the application of gut microbiota modification for the treatment of immune-related diseases, such as fecal microbiota transplantation and probiotics, remain quite challenging. Therefore, more research is needed into the role and mechanisms of these therapeutics.

Access to and acceptability of sexual and reproductive health, harm reduction and other essential health services among people who inject drugs in Durban, South Africa.

BACKGROUND: People who inject drugs (PWID) are at risk of HIV acquisition. The number of PWID in South African cities is increasing, and in spite of an advanced HIV prevention and treatment programme, there are PWID who experience challenges accessing sexual and reproductive health (SRH) and HIV related services. Access to and acceptability of SRH and harm reduction services by PWID needs to be further understood and explored. METHODS: In-depth interviews (IDIs) were conducted with 10 key stakeholders and 11 PWID, in Durban, South Africa. Interviews were transcribed and translated. Data were thematically analysed using Dedoose software. RESULTS: Participants described stigma/discrimination from healthcare workers and other clients accessing services as barriers to accessing healthcare services. They were concerned about long waiting times at healthcare facilities because of possibilities of withdrawal, as well as lost opportunities to "hustle". Targeted, non-discriminatory services, as well as mobile clinics existed in the city. Non-governmental organisations reportedly worked together with the public sector, facilitating access to HIV and TB prevention and treatment services. There were also needle exchange programmes and a harm reduction clinic in the city. However, there was limited access to contraceptive and STI services. Although there was reportedly good access to HIV and TB and harm reduction services in the city of Durban, uptake was low. CONCLUSIONS: The integration of services to enable PWID to access different services under one roof is critical. There is also a need to strengthen linkages between public and private healthcare, and ensure services are provided in a non-discriminatory environment. This will facilitate uptake and access to more comprehensive SRH and harm reduction services for PWID in Durban, South Africa.

Physiology of Vitamin D-Focusing on Disease Prevention.

Vitamin D is a crucial micronutrient, critical to human health, and influences many physiological processes. Oral and skin-derived vitamin D is hydroxylated to form calcifediol (25(OH)D) in the liver, then to 1,25(OH)2D (calcitriol) in the kidney. Alongside the parathyroid hormone, calcitriol regulates neuro-musculoskeletal activities by tightly controlling blood-ionized calcium concentrations through intestinal calcium absorption, renal tubular reabsorption, and skeletal mineralization. Beyond its classical roles, evidence underscores the impact of vitamin D on the prevention and reduction of the severity of diverse conditions such as cardiovascular and metabolic diseases, autoimmune disorders, infection, and cancer. Peripheral target cells, like immune cells, obtain vitamin D and 25(OH)D through concentration-dependent diffusion from the circulation. Calcitriol is synthesized intracellularly in these cells from these precursors, which is crucial for their protective physiological actions. Its deficiency exacerbates inflammation, oxidative stress, and increased susceptibility to metabolic disorders and infections; deficiency also causes premature deaths. Thus, maintaining optimal serum levels above 40 ng/mL is vital for health and disease prevention. However, achieving it requires several times more than the government's recommended vitamin D doses. Despite extensive published research, recommended daily intake and therapeutic serum 25(OH)D concentrations have lagged and are outdated, preventing people from benefiting. Evidence suggests that maintaining the 25(OH)D concentrations above 40 ng/mL with a range of 40-80 ng/mL in the population is optimal for disease prevention and reducing morbidities and mortality without adverse effects. The recommendation for individuals is to maintain serum 25(OH)D concentrations above 50 ng/mL (125 nmol/L) for optimal clinical outcomes. Insights from metabolomics, transcriptomics, and epigenetics offer promise for better clinical outcomes from vitamin D sufficiency. Given its broader positive impact on human health with minimal cost and little adverse effects, proactively integrating vitamin D assessment and supplementation into clinical practice promises significant benefits, including reduced healthcare costs. This review synthesized recent novel findings related to the physiology of vitamin D that have significant implications for disease prevention.

The Need for a Prevention Program for Child Sexual Abuse in Brazil: A Report of Shortfall Care to Pedophilia and its Critical Consequences.

From a case report of a person with pedophilic disorder, this paper focuses on the issue of pedophilia, child sexual abuse, and the need for specific prevention and treatment strategies in Brazil. It seems inevitable to increase awareness for this topic within the mental health care system to protect children and reduce the risk for sexual offense in individuals at-risk. This is a case report of an individual, known by medical-psychiatric and forensic facilities for a past history of patricide, who revealed his pedophilic fantasies and behavior belatedly. To assess a pedophilic disorder and screen for other paraphilic contents, a screening questionnaire and clinical interview were used during the patient hospitalization in 2020 for a proper evaluation of sexual history and past offending behaviors. A review of the literature on pedophilia prevention programs was also carried out. WW is a middle-aged man admitted to a psychiatric unit for a severe episode of major depressive disorder and at risk of suicide. During recovery, he reported pedophilic fantasies and behaviors in his life. Sexual fantasies involving children and actual sexual offenses have remained unknown to mental health professionals and unreported to legal authorities. WW's case alarmingly emphasizes the need for the training of health care professionals and for preventive strategies in Brazil for those who are at risk of engaging in offending sexual behaviors in a combined and intensive effort to protect children from sexual offense.

Targeting ferroptosis using Chinese herbal compounds to treat respiratory diseases.

BACKGROUND: Respiratory diseases pose a grave threat to human life. Therefore, understanding their pathogenesis and therapeutic strategy is important. Ferroptosis is a novel type of iron-dependent programmed cell death, distinct from apoptosis, necroptosis, and autophagy, characterised by iron, reactive oxygen species, and lipid peroxide accumulation, as well as glutathione (GSH) depletion and GSH peroxidase 4 (GPX4) inactivation. A close association between ferroptosis and the onset and progression of respiratory diseases, including chronic obstructive pulmonary disease, acute lung injury, bronchial asthma, pulmonary fibrosis, and lung cancer, has been reported. Recent studies have shown that traditional Chinese medicine (TCM) compounds exhibit unique advantages in the treatment of respiratory diseases owing to their natural properties and potential efficacy. These compounds can effectively regulate ferroptosis by modulating several key signalling pathways such as system Xc- -GSH-GPX4, NCOA4-mediated ferritinophagy, Nrf2-GPX4, and Nrf2/HO-1, thus playing a positive role in improving respiratory diseases. PURPOSE: This comprehensive review systematically outlines the regulatory role of ferroptosis in the onset and progression of respiratory diseases and provides evidence for treating respiratory diseases by targeting ferroptosis with TCM compounds. These insights aim to offer potential remedies for the clinical prevention and treatment of respiratory diseases. STUDY DESIGN AND METHODS: We searched scientific databases PubMed, Web of Science, Scopus, and CNKI using keywords such as "ferroptosis","respiratory diseases","chronic obstructive pulmonary disease","bronchial asthma","acute lung injury","pulmonary fibrosis","lung cancer","traditional Chinese medicine","traditional Chinese medicine compound","monomer", and "natural product" to retrieve studies on the therapeutic potential of TCM compounds in ameliorating respiratory diseases by targeting ferroptosis. The retrieved data followed PRISMA criteria (preferred reporting items for systematic review). RESULTS: TCM compounds possess unique advantages in treating respiratory diseases, stemming from their natural origins and proven clinical effectiveness. TCM compounds can exert therapeutic effects on respiratory diseases by regulating ferroptosis, which mainly involves modulation of pathways such as system Xc- -GSH-GPX4,NCOA4-mediated ferritinophagy, Nrf2-GPX4, and Nrf2/HO-1. CONCLUSION: TCM compounds have demonstrated promising potential in improving respiratory diseases through the regulation of ferroptosis. The identification of specific TCM-related inducers and inhibitors of ferroptosis holds great significance in developing more effective strategies. However, current research remains confined to animal and cellular studies, emphasizing the imperative for further verifications through high-quality clinical data.

Silymarin effectively prevents and treats Eimeria tenella infection in chicks.

Silymarin, a botanical medicine derived from milk thistle seeds and is known to improve chicken growth and gut health when added to the feed. However, its role in the prevention and treatment of chicken coccidiosis remains unclear. This study investigated the efficacy of various doses of silymarin in preventing and treating Eimeria tenella infection in chicks. A total of 180 one-day-old specific pathogen-free chicks were randomized into six groups of 30 chicks each, no treatment (NC group); E. tenella infection (CC group); diclazuril medication during d 14 to 21 and E. tenella infection (DC group); and three groups infected with E. tenella and administered low, medium, or high doses of silymarin during d 12 to 21. All groups except NC were infected with E. tenella on d 14, with indicators observed on d 21. The growth performance was higher in the silymarin treated groups than that in the CC group, and the oocyst count per gram of manure, blood stool, and cecal lesion scores decreased. The medium-dose silymarin group exhibited the best treatment effect. Additionally, the silymarin groups displayed improved histological, morphology, and intestinal barrier integrity. The amounts of proinflammatory factors and harmful bacteria in the cecum were also reduced. Additionally, the activity of serum and cecal antioxidant enzymes, as well as the abundance of beneficial gut microbiota, increased in the cecum. In conclusion, this study demonstrated that silymarin can prevent and treat E. tenella infections. These data provide a scientific and conceptual basis for the development of a botanical dietary supplement from silymarin for the treatment and control of coccidiosis in chicks.

Effects of three kinds of Chinese herbs on growth performance, oocysts output and gut microbiota in growing lambs with coccidiosis.

Coccidiosis is a protozoan intestinal disease that reduces the production of the sheep industry and causes large economic losses for sheep. Although chemically synthesised drugs are routinely employed to treat coccidiosis in sheep, the anticoccidial drug resistance and drug residues in edible meat have prompted an urgent search for alternatives. Herein, the anticoccidial properties of diclazuril, a conventional anticoccidial drug, and Allium sativum, Houttuynia cordata and Portulaca oleracea were assessed. Forty 45-day-old lambs naturally infected with Eimeria spp. were selected and randomly divided into five groups. The results showed that the sheep treated for coccidiosis had considerably decreased average daily gain (ADG) during both administration and withdrawal of the drug compared to the control group. Furthermore, at days 14, 21, 28 and 35, respectively, the three herbs and diclazuril had similar anticoccidial effects, with lower oocysts per gram (OPG) than the control group. On day 78, OPG in the three herbal groups was significantly lower than in the diclazuril group. In addition, the abundance and composition of the gut microbiota were changed in sheep treated with the three herbs and diclazuril compared to the untreated sheep. Moreover, some intestinal microorganisms have a correlation with OPG and ADG when using Spearman correlation analysis. In summary, our results suggest that all three herbs produce anticoccidial effects similar to diclazuril and modulate the balance of gut microbiota in growing lambs.

Discovery of Pyrido[1,2-α] Pyrimidinone Mesoionic Compounds as Potential Control Agents Against Potato Virus Y.

Potato virus Y (PVY) relies on aphids and tubers to spread in the field and causes serious economic losses in the potato industry. Here, we found that pyrido[1,2-α] pyrimidinone mesoionic compounds with insecticidal activity against aphids possessed a good inhibitory effect on PVY. Among them, compound 35 had the best inhibitory activity against PVY (EC50 = 104 µg/mL), even superior to that of ningnanmycin (125 µg/mL). The fluorescence and qPCR results confirmed that compound 35 could inhibit the proliferation of PVY in Nicotiana benthamiana. Preliminary experiments on the mechanism of action indicated that compound 35 had good binding affinity with the coat protein (CP), which plays an essential role in aphid-PVY interactions. Molecular docking revealed that compound 35 could bind to the pocket of CP formed by Ser52, Glu204, and Arg208. Compound 35 had substantially lower binding affinity (Kd) values with CPS52A (219 µM), CPE204A (231 µM), and CPR208A (189 µM) than those with CPWT (5.80 µM). A luciferase assay confirmed that mutating Ser52, Glu204, and Arg208 significantly affected the expression level of CP and further reduced virus proliferation. Therefore, the broad-spectrum activity of compound 35 provides a unique strategy for the prevention and treatment of PVY.

The role of mitochondrial dynamics and mitophagy in skeletal muscle atrophy: from molecular mechanisms to therapeutic insights.

Skeletal muscle is the largest metabolic organ of the human body. Maintaining the best quality control and functional integrity of mitochondria is essential for the health of skeletal muscle. However, mitochondrial dysfunction characterized by mitochondrial dynamic imbalance and mitophagy disruption can lead to varying degrees of muscle atrophy, but the underlying mechanism of action is still unclear. Although mitochondrial dynamics and mitophagy are two different mitochondrial quality control mechanisms, a large amount of evidence has indicated that they are interrelated and mutually regulated. The former maintains the balance of the mitochondrial network, eliminates damaged or aged mitochondria, and enables cells to survive normally. The latter degrades damaged or aged mitochondria through the lysosomal pathway, ensuring cellular functional health and metabolic homeostasis. Skeletal muscle atrophy is considered an urgent global health issue. Understanding and gaining knowledge about muscle atrophy caused by mitochondrial dysfunction, particularly focusing on mitochondrial dynamics and mitochondrial autophagy, can greatly contribute to the prevention and treatment of muscle atrophy. In this review, we critically summarize the recent research progress on mitochondrial dynamics and mitophagy in skeletal muscle atrophy, and expound on the intrinsic molecular mechanism of skeletal muscle atrophy caused by mitochondrial dynamics and mitophagy. Importantly, we emphasize the potential of targeting mitochondrial dynamics and mitophagy as therapeutic strategies for the prevention and treatment of muscle atrophy, including pharmacological treatment and exercise therapy, and summarize effective methods for the treatment of skeletal muscle atrophy.

Effect of anticoagulation on the incidence of venous thromboembolism, major bleeding, and mortality among hospitalized COVID-19 patients: an updated meta-analysis.

Objective: Anticoagulation is crucial for patients hospitalized with coronavirus disease 2019 (COVID-19) due to the high risk of venous thromboembolism (VTE). However, the optimal anticoagulation regimen needs further exploration. Therefore, we evaluated the efficacy and safety of diverse anticoagulation dosage dosages for COVID-19. Methods: An updated meta-analysis was performed to assess the effect of thromboprophylaxis (standard, intermediate, and therapeutic dose) on the incidence of VTE, mortality and major bleeding among COVID-19 patients. Literature was searched via PubMed, EMBASE, Web of Science, and China National Knowledge Infrastructure (CNKI) database. The odds ratio (OR) and 95% confidence interval (CI) were calculated for effect estimates. Results: Nineteen studies involving 25,289 participants without VTE history were included. The mean age of patients was 59.3 years old. About 50.96% were admitted to the intensive care unit. In the pooled analysis, both therapeutic-dose and intermediate-dose anticoagulation did not have a significant advantage in reducing VTE risk over standard dosage (OR = 1.09, 95% CI: 0.58-2.02, and OR = 0.89, 95% CI: 0.70-1.12, respectively). Similarly, all-cause mortality was not further decreased in either therapeutic-dose group (OR = 1.12, 95% CI: 0.75-1.67) or intermediate-dose group (OR = 1.34, 95% CI: 0.83-2.17). While the major bleeding risk was significantly elevated in the therapeutic-dose group (OR = 2.59, 95%CI: 1.87-3.57) as compared with the standard-dose regimen. Compared with intermediate dosage, therapeutic anticoagulation did not reduce consequent VTE risk (OR = 0.85, 95% CI: 0.52-1.38) and all-cause mortality (OR = 0.84, 95% CI: 0.60-1.17), but significantly increased major bleeding rate (OR = 2.42, 95% CI: 1.58-3.70). In subgroup analysis of patients older than 65 years, therapeutic anticoagulation significantly lowered the incidence of VTE in comparation comparison with standard thromboprophylaxis, however, at the cost of elevated risk of major bleeding. Conclusion: Our results indicated that for most hospitalized patients with COVID-19, standard-dose prophylactic anticoagulation might be the optimal choice. For elderly patients at low risk of bleeding, therapeutic-dose anticoagulation could further reduce VTE risk and should be considered especially when there were other strong risk factors of VTE during hospital stay.

Correlation between jingjin injury and wulao and the relevant prevention and treatment strategies. / 经筋损伤与"五劳"çš„ç›¸å ³æ€§åŠé˜²æ²»ç­–ç•¥.

The paper explores the correlation between jingjin (muscle regions of meridians, sinews/fascia) injury and wulao (five types of exhaustion) and the relevant prevention and treatment strategies, and determines the internal mechanism of the disease so as to provide the ideas for prevention and treatment of jingjin injury. Wulao may result in jingjin injury not only through the damages of blood, qi, muscles, bones and tendons indirectly, but also through the damage of soft tissues directly. The great attention should be paid to preventing from jingjin injury, especially wulao, due to which, the appropriate combination of the static and the dynamic skills is emphasized in the way of physical exercise. When the injury occurred, the conditions of the whole body should be analyzed comprehensively and the local affected regions be concentrated simultaneously in treatment. For the indirect injury, the holistic idea should be the basis of regulating five zang organs and restoring the physiological functions of blood, qi, muscles, bones and sinews so as to adjust jingjin. Regarding the direct injury, the staging regimen for the local treatment is considered to harmonize qi and blood and balance sinews and bones. When the injury has been cured, the physical exercise is recommended to strengthen sinews and bones according to individual conditions to prevent from recurrence.

Bridging the Gap: A Holistic View of Personality Factors in Individuals With and Without Alcohol Use.

This comprehensive review examines the intricate interplay between personality factors and alcohol use, shedding light on the dynamic relationship that shapes the initiation, progression, and outcomes of alcohol-related behaviors. The exploration encompasses vital personality traits such as sensation seeking, impulsivity, neuroticism, extroversion, agreeableness, conscientiousness, and openness to experience. The bidirectional nature of this association is underscored, emphasizing how personality influences and is influenced by alcohol consumption patterns. Protective personality factors, including resilience, emotional regulation, and social support, are identified as crucial elements in mitigating the risk of alcohol use disorders (AUDs). The implications for clinical practice advocate for tailored interventions that address individual personality profiles, while policy considerations highlight the need for targeted prevention efforts that acknowledge the diverse ways individuals respond to alcohol use. Furthermore, a call for future research emphasizes emerging perspectives, improved methodologies, and ongoing exploration of intervention strategies to advance our understanding of this complex relationship and refine approaches for prevention and treatment. As we navigate this evolving field, the insights gleaned hold promise for shaping more compelling and nuanced interventions to address the diverse needs of individuals affected by AUDs.

Evolving liver disease insights from NAFLD to MASLD.

The recent renaming of 'non-alcoholic fatty liver disease' (NAFLD) to 'metabolic dysfunction-associated steatotic liver disease' (MASLD) emphasizes metabolic dysfunction in steatotic liver disease and advocates for tailored, comprehensive treatment strategies, driving forward the development of personalized care and innovative therapeutic approaches.

The intestinal epithelial-macrophage-crypt stem cell axis plays a crucial role in regulating and maintaining intestinal homeostasis.

The intestinal tract plays a vital role in both digestion and immunity, making its equilibrium crucial for overall health. This equilibrium relies on the dynamic interplay among intestinal epithelial cells, macrophages, and crypt stem cells. Intestinal epithelial cells play a pivotal role in protecting and regulating the gut. They form vital barriers, modulate immune responses, and engage in pathogen defense and cytokine secretion. Moreover, they supervise the regulation of intestinal stem cells. Macrophages, serving as immune cells, actively influence the immune response through the phagocytosis of pathogens and the release of cytokines. They also contribute to regulating intestinal stem cells. Stem cells, known for their self-renewal and differentiation abilities, play a vital role in repairing damaged intestinal epithelium and maintaining homeostasis. Although research has primarily concentrated on the connections between epithelial and stem cells, interactions with macrophages have been less explored. This review aims to fill this gap by exploring the roles of the intestinal epithelial-macrophage-crypt stem cell axis in maintaining intestinal balance. It seeks to unravel the intricate dynamics and regulatory mechanisms among these essential players. A comprehensive understanding of these cell types' functions and interactions promises insights into intestinal homeostasis regulation. Moreover, it holds potential for innovative approaches to manage conditions like radiation-induced intestinal injury, inflammatory bowel disease, and related diseases.

En la distribución geográfica por las Áreas de Salud, el 51,4% de las personas procedían de 4 centros de salud y en 9 centros de salud se incluían más del 70% de los nuevos diagnosticados. Conclusión Conocer mejor la distribución geográfica de los nuevos diagnósticos de VIH por Áreas Sanitarias nos permite identificar las zonas de mayor riesgo de transmisión, para así poder dirigir y efectuar medidas de prevención, diagnóstico y tratamiento precoz (AU)

Introduction Countering HIV infection remains a primary objective of the Spanish National Health System. Emergency services play a crucial role in reducing missed diagnostic opportunities, with estimates suggesting that one in 3 such opportunities occur here. The aim of the study is to examine the geographical dispersion of newly diagnosed HIV cases, within a downtown Madrid hospital. Methods This is an observational, descriptive, retrospective study evaluating the geographical distribution of new HIV diagnoses in the care area of a tertiary University Hospital in the Community of Madrid. Results Three hundred and eighty-seven individuals with a new diagnosis of HIV infection between 2018 and 2020 were analysed, the majority being young people with an average age of 36±9 years. 86% were gay, bisexual and other men who have sex with men and 48.6% were immigrants. 15.3% presented with CD4+<200cells/mm3 and 9.5% with an AIDS-defining illness. 32.7% and 5.1% had an RNA-HIV-1>100,000copies/mL and >500,000copies/mL, respectively, with up to 13.7% of subjects presenting resistance mutations at diagnosis. Geographically, 51.4% of individuals came from 4 Health Centres and more than 70% of the new diagnoses were included in nine Health Centres. Conclusion Better understanding the geographical distribution of new HIV diagnoses by health areas allows us to identify areas of higher transmission risk, thereby directing and implementing prevention, early diagnosis, and treatment measures (AU)
