Background: Adolescent pregnancy is a public health problem of concern in developed, developing and underdeveloped countries. Trends in developing and underdeveloped countries are higher and account for most adverse pregnancy outcomes. Adolescence is a period of transition between childhood and adulthood. The burden of coping with changes with this transition and at the same time preparing for childbirth puts pregnant adolescent girls on edge. Childbirth and childrearing are critical moments that require support and specialized skills to nurture healthy infants. Aim: This study aims to assess the readiness of adolescent expectant mothers towards childbirth and childrearing in the Komenda/Edina/Eguafo/Abirem (KEEA) district of the central region of Ghana. Methods: This study utilized the total population sampling technique to collect data from three sites that offer specialized adolescent antenatal services within the KEEA district of the central region of Ghana. Data were analyzed using SPSS version 22.0 and results presented as descriptive statistics. Results: This study assessed maternal readiness for childbirth and childrearing among 98 pregnant adolescent girls. The study was dominated by late adolescents who made up 86.7% of study participants. Regarding readiness for childrearing, the majority (74.5%) said they could not independently cater for their children and will require some support. The majority (52.0%) have had some form of counseling with a greater number (41.2%) coming from parents. Regarding readiness to embrace childbirth, the majority (82.4%) of respondents said they had companions who were willing to support them during childbirth. The majority (57.1%) of responden

Background: Hepatitis-B (Hep-B) infection is a global public health problem of great concern which affects more than 5% of the local population in Sub-Saharan Africa. This study assessed students’ knowledge, attitude and practices towards Hepatitis B infection and vaccination at the University of Health and Allied Sciences, Ghana. Methods: A cross-sectional quantitative descriptive survey was conducted among 262 Public Health students of the University of Health and Allied Science of the Volta region of Ghana, using a multi-stage sampling technique in selecting participants. A structured questionnaire was used to collect data from the participants. Data was analyzed using SPSS Version 20.1. Results: Study respondents were mostly males, forming 69.8% as against 30.2% of their female counterparts. All (262) respondents had knowledge on Hep-B infection and the availability of a vaccine for preventing Hepatitis infection. However, despite their knowledge of existence, the majority (56.9%) of the respondents felt they did not need to be protected from Hep-B infection. Majority (58.8%) of the total respondents have been vaccinated against Hep-B infection. The study identified the cost of vaccines as a major setback to non-vaccination. However, out of the 41.2% respondents who were not vaccinated against Hep B infection, majority (50.9%) of them were not willing to be vaccinated even if it was offered to them at no cost. Conclusion: There was a significantly high level of knowledge on Hep-B infection and the availability of vaccine for Hep-B infection among students. However, the majority of the respondents felt they did not need to be protected from Hep-B infection. More education is needed on the importance of vaccination as an effective measure for controlling Hepatitis infection.

Endoplasmic reticulum stress,autophagy,neuroinflammation,and sigma 1 receptors as contributors to depression and its treatment

引用

Neural Regeneration Research 2024年第10期19卷 2202-2211页

The etiological factors contributing to depression and other neuropsychiatric disorders are largely undefined. Endoplasmic reticulum stress pathways and autophagy are well-defined mechanisms that play critical functions in recognizing and resolving cellular stress and are possible targets for the pathophysiology and treatment of psychiatric and neurologic illnesses. An increasing number of studies indicate the involvement of endoplasmic reticulum stress and autophagy in the control of neuroinflammation, a contributing factor to multiple neuropsychiatric illnesses. Initial inflammatory triggers induce endoplasmic reticulum stress, leading to neuroinflammatory responses. Subsequently, induction of autophagy by neurosteroids and other signaling pathways that converge on autophagy induction are thought to participate in resolving neuroinflammation. The aim of this review is to summarize our current understanding of the molecular mechanisms governing the induction of endoplasmic reticulum stress, autophagy, and neuroinflammation in the central nervous system. Studies focused on innate immune factors, including neurosteroids with anti-inflammatory roles will be reviewed. In the context of depression, animal models that led to our current understanding of molecular mechanisms underlying depression will be highlighted, including the roles of sigma 1 receptors and pharmacological agents that dampen endoplasmic reticulum stress and associated neuroinflammation.

Metabolism is a fundamental process by which biochemicals are broken down to produce energy(catabolism) or used to build macromolecules(anabolism). Metabolism has received renewed attention as a mechanism that generates molecules that modulate multiple cellular responses. This was first identified in cancer cells as the Warburg effect, but it is also present in immunocompetent cells. Studies have revealed a bidirectional influence of cellular metabolism and immune cell function, highlighting the significance of metabolic reprogramming in immune cell activation and effector functions. Metabolic processes such as glycolysis, oxidative phosphorylation, and fatty acid oxidation have been shown to undergo dynamic changes during immune cell response, facilitating the energetic and biosynthetic demands. This review aims to provide a better understanding of the metabolic reprogramming that occurs in different immune cells upon activation, with a special focus on central nervous system disorders. Understanding the metabolic changes of the immune response not only provides insights into the fundamental mechanisms that regulate immune cell function but also opens new approaches for therapeutic strategies aimed at manipulating the immune system.

Glyphosate as a direct or indirect activator of pro-inflammatory signaling and cognitive impairment

引用

Neural Regeneration Research 2024年第10期19卷 2212-2218页

作者： Yukitoshi Izumi Kazuko A.O'Dell charles F.Zorumski Department of Psychiatry Washington University School of MedicineSt.LouisMOUSA Taylor Family Institute for Innovative Psychiatric Research Washington University School of MedicineSt.LouisMOUSA

Glyphosate-based herbicides are widely used around the world, making it likely that most humans have significant exposure. Because of habitual exposure, there are concerns about toxicity including neurotoxicity that could result in neurological, psychiatric, or cognitive impairment. We recently found that a single injection of glyphosate inhibits long-term potentiation, a cellular model of learning and memory, in rat hippocampal slices dissected 1 day after injection, indicating that glyphosate-based herbicides can alter cognitive function. Glyphosate-based herbicides could adversely affect cognitive function either indirectly and/or directly. Indirectly, glyphosate could affect gut microbiota, and if dysbiosis results in endotoxemia(leaky gut), infiltrated bacterial by-products such as lipopolysaccharides could activate pro-inflammatory cascades. Glyphosate can also directly trigger pro-inflammatory cascades. Indeed, we observed that acute glyphosate exposure inhibits long-term potentiation in rat hippocampal slices. Interestingly, direct inhibition of long-term potentiation by glyphosate appears to be similar to that of lipopolysaccharides. There are several possible measures to control dysbiosis and neuroinflammation caused by glyphosate. Dietary intake of polyphenols, such as quercetin, which overcome the inhibitory effect of glyphosate on long-term potentiation, could be one effective strategy. The aim of this narrative review is to discuss possible mechanisms underlying neurotoxicity following glyphosate exposure as a means to identify potential treatments.
