A new epidemiological study found that fluoride exposure from drinking water associates with decreased testosterone levels in young and middle-aged men.
Testosterone dropped most sharply in 18-39 year-olds based on fluoride burden. Surprisingly, in older men with higher fluoride exposure, testosterone increased with age instead of declining as expected. This complex relationship hints that fluoride may disrupt multiple hormonal pathways beyond the male reproductive axis.
A novel study reveals fluoride affects serum testosterone in a complex, age-specific manner, adding evidence that environmental toxicants may contribute to declining hormonal function in younger males.
Published in Biological Trace Element Research, the cross-sectional study examined fluoride exposure and two reproductive biomarkers, testosterone and androgen binding protein (ABP), in over 300 Chinese farmers.1 Scientists divided participants into higher and lower fluoride exposure groups based on urinary fluoride levels.
Compared to the lower exposure group, men with elevated fluoride measured significantly lower testosterone overall. This depletion was most pronounced in 18-39 year olds. Paradoxically, among higher-exposed middle aged and older men, testosterone increased slightly with age instead of undergoing the expected age-related decline.
Meanwhile, ABP remained unaffected across groups regardless of fluoride burden and age. As ABP governs testosterone transport and tissue uptake, results indicate fluoride direct

This is just a pilot study, so it's hard to tell if there will be therapeutics derived from this, but it's interesting to see spa treatments pitched for releaving long-covid symptoms. This is the 3rd or 4th study in this area I've seen. Just kinda neat.
Abstract Background The long-COVID syndrome is characterised by a plethora of symptoms. Given its social and economic impact, many studies have stressed the urgency of proposing innovative strategies other than hospital settings. In this double-blind randomised case-control trial, we investigate the effects of sulfur thermal water inhalations, rich in H2S, compared to distilled water inhalations on symptoms, inflammatory markers, nasal microbiome in long-COVID patients.
Methods 30 outpatients aged 18-75, with positive diagnosis for long-COVID were randomised in two groups undergoing 12 consecutive days of inhalations. The active Group (STW) received sulfur thermal water inhalations whereas the placebo group received inhalations of sterile distilled non-pyrogenic water (SDW). Each participant was tested prior treatment at day 1 (T0), after the inhalations at day 14 (T1) and at 3 months follow-up (T2). At each time point, blood tests, nasal swabs for microbiome sampling, pulmonary functionality tests (PFTs) and pro-inflammatory marker measure were performed.
Results The scores obtained in the administered tests (6MWT, Borg score, and SGRQ) at T0, showed a significant variation in STW group, at T1 and T2. Serum cytokine levels and other inflammatory biomarkers reported a statistically significant decrease. Some specific parameters of PFT's showed ameliorations in STW group only. Changes in the STW nasopharyngeal microbiota composition were noticed, especially from T0 to T2.
Conclusions Inhalations of sulfur thermal water exerted objective and subjective improvements on subjects affected by long-COVID. Significant reduction of inflammatory markers, dyspnea scores and quantitative and qualitative changes in the nasopharyngeal microbiome were also assessed.

Alzheimer's Disease: biomarkers and neuroimaging markers cheatsheet for research articles
As Alzheimer's Disease (AD) research skews toward understanding the brain than the pathogenic proteins, studies exploring biomarkers and neuroimaging are hopeful toward developing a method for successful prevention of AD. A biomarker is a molecule, whose presence indicates abnormality or disease, and thus, is crucial in diagnostic procedures. Levels of certain molecules is notably altered in cerebrospinal fluid and in blood plasma, which helps in diagnosing the occurrence of AD. Neuroimaging involves the use of techniques such as magnetic resonance imaging and computed tomography to observe neuronal activity in the brain. This is good news, especially for AD, as the asymptomatic stage of the disease can be identified early enough.
Although the exact function and involvement in clinical practice is not profuse, altered concentrations of these biomarkers in plasma or cerebrospinal fluid encourage further research:
Amyloid and tau serve as the unsurprising biomarkers of AD pathology.
Neurofilament-light chain (NF-L) and visinin-like protein-1 (VILIP-1) are the most promising biomarkers of neuronal injury.
Post-synaptic protein neurogranin (Ng) and pre-synaptic proteins synaptosome-associated protein-25 (SNAP-25) and synaptotagmin-1 (Syt-1) are considered major biomarkers of synaptic injury.
Brain and CSF levels of tumor necrosis factor alpha (TNF-α) and increased levels of interleukin group of proteins (ILs) indicate intensified microglial response to neuroinflammation.
TREM2 receptor and YKL-40 glycoprotein are also reliable indicators of inflammation and impaired clearance of amyloid beta.
Heart-type fatty acid-binding protein (hFABP) could be a marker for pathology in blood vessels supplying the brain. Some vascular markers also show potential as markers of vascular injury in AD: von Willebrand factor (vWF) and monokine induced by γ-interferon (MIG, also known as CXCL-9).
Concentrations of TAR-DNA binding protein (TDP-43) in the brain and plasma and serum indicate, even contribute to, inflammation, mitochondrial dysfunction, and neuronal/synaptic injury in AD.
Neuroimaging techniques reveal structural, functional, and diffusion-related activities of the neurons. To identify them, markers are tracked in images obtained. Each marker is determined with the activity and biochemistry of the group of/individual neurons being studied.
Structural MRI will show location and severity of atrophy which can be identified in grey scale images by applying programs that create analogous color grading.
Functional MRI relies on blood oxygenation level dependent (BOLD) signal which reflects changes in blood oxygenation levels in response to neural activity.
Diffusion weighted imaging (DWI) focuses on diffusion of water molecules. A tensor model is applied to images obtained from DWI. The diffusion tensor imaging (DTI) metrics thus obtained help in studying connectivity through structural integrity of white matter tracts.
Tractography involves 3-D reconstruction of white matter as observed in DWI, which provides a more detailed look into a patient’s neural networks.
In positron emission tomography (PET), markers are identified and labelled so their features or functions can be traced during this procedure to obtain a resulting PET scan. The imaging procedure is named according to its marker: amyloid-PET, tau-PET, FDG-PET, inflammation-PET, receptor-PET.
FDA approved drugs Galantamine, Rivastigmine, and Donepezil alleviate symptoms such as memory loss and confusion in mild to moderate AD, although their effects seem to be negligible. They also cause nausea and vomiting as side effects and are not suitable for every patient. Recently approved drugs, Aducanumab and Lecanemab focus on removing accumulated amyloid. Their effectiveness is still doubted on the basis of studies finding that targeting amyloid has little to do with curbing the actual progression of the disease.

the only FDA approved biomarker for traumatic brain injury, the Brain Trauma Indicator™
The Brain Trauma Indicator™ (BTI™) works by measuring levels of proteins, known as UCH-L1 and GFAP, that are released from the brain into blood and measured within 12 hours of head injury. Levels of these blood proteins after mTBI/concussion can help predict which patients may have intracranial lesions visible by CT scan and which won’t. Being able to predict if patients have a low probability of intracranial lesions can help health care professionals in their management of patients and the decision to perform a CT scan. Test results can be available within 3 to 4 hours.
The Brain Trauma Indicator was able to predict the presence of intracranial lesions on a CT scan 97.5 percent of the time and those who did not have intracranial lesions on a CT scan 99.6 percent of the time
A step-wise increase in biomarker concentrations over the continuum of severity from mild to severe TBI was detected. Of the two, only the neuronal biomarker UCH-L1 had the potential to detect acute intracranial lesions, as assessed by CT. Most importantly, both markers were substantially increased in TBI patients with a normal CT. Serum UCH-L1 and GFAP concentrations also strongly predicted poor outcomes

The circulating inactive form of matrix Gla Protein (ucMGP) as a biomarker for cardiovascular calcification
Abstract
Objective: Matrix gamma-carboxyglutamate (Gla) protein (MGP) is a vitamin K-dependent protein and a strong inhibitor of vascular calcification. Vitamin K deficiency leads to inactive uncarboxylated MGP (ucMGP), which accumulates at sites of arterial calcification. We hypothesized that as a result of ucMGP deposition around arterial calcification, the circulating fraction of ucMGP is decreased. Here we report on the development of an ucMGP assay and the potential diagnostic utility of monitoring serum ucMGP levels.
Methods and results: An ELISA-based assay was developed with which circulating ucMGP can be determined. Serum ucMGP levels were measured in healthy subjects (n = 165) and in four patient populations; patients who underwent angioplasty (n = 30), patients with aortic stenosis (n = 25), hemodialysis patients (n = 52), and calciphylaxis patients (n = 10). All four patient populations had significantly lower ucMGP levels. In angioplasty patients and in those with aortic stenosis, some overlap was observed with the control population. However, in the hemodialysis and calciphylaxis populations, virtually all subjects had ucMGP levels below the normal adult range.
Conclusion: Serum ucMGP may be used as a biomarker to identify those at risk for developing vascular calcification. This assay may become an important tool in the diagnosis of cardiovascular calcification.

Is Pentraxin 3 A Marker in Pathogenesis of Metabolic Syndrome?
Is Pentraxin 3 A Marker in Pathogenesis of Metabolic Syndrome? in Biomedical Journal of Scientific & Technical Research
Pentraxin 3 (PTX3) is an acute-phase protein that is structurally similar to C-reactive protein (CRP). Macrophages, endothelial cells, and adipocytes all produce PTX3 in response to inflammatory stimuli, but hepatocytes are the main source of CRP. PTX3 could play a role in the genesis of obesity, metabolic syndrome (MetS), and CRP because obesity and MetS are chronic inflammatory diseases [1]. MetS is a group of risk factors that includes glucose intolerance, abnormal lipid profiles, hypertension, and abdominal obesity [2- 6]. Each of these factors has been linked to atherosclerosis and cardiovascular disease. The majority of current research has found a link between MetS components and inflammatory mediators such as interleukin-6, tumor necrosis factor-α, and CRP [7]. Furthermore, serum CRP levels were shown to be greater in individuals with more risk factors for MetS, and higher serum CRP levels were related to higher occurrence of cardiovascular events, reflecting the prognostic relevance of MetS severity [8]. In particular, many types of cells, including macrophages, dendritic cells, neutrophils, adipose cells, fibroblasts, and vascular endothelial cells, have been reported to produce PTX-3, a newly recognized acute-phase reactant that is structurally and functionally similar to CRP [9]. The link between MetS and PTX-3 hasn’t been well investigated, and the available evidence appears to be discordant. Several investigations have found a link between MetS components and inflammatory mediators such as interleukin-6, tumor necrosis factor-α, and CRP [7]. The hs-CRP is the most well-known and validated of these inflammatory biomarkers. Insulin resistance, endothelial dysfunction, and unfavorable cardiovascular events have all been linked to high levels of hs-CRP [10,11].

NASH: Bridging the Gap Between Lifestyle Disease and Epidemic Status
Nonalcoholic Steatohepatitis (NASH) has swiftly evolved from a relatively unknown health concern to a major public health challenge, standing at the crossroads between a lifestyle-related disease and a growing global epidemic. A more severe form of nonalcoholic fatty liver disease (NAFLD), NASH is characterized by the buildup of fat in the liver accompanied by inflammation and scarring. Left unchecked, it can lead to cirrhosis, liver failure, or hepatocellular carcinoma. The rapid rise of obesity, diabetes, and metabolic syndrome worldwide has fueled the growth of NASH, making it a pressing concern in both healthcare and policy circles.
Understanding the Rising Threat of NASH
Once thought to be rare, NASH now affects an estimated 5-6% of the global population, with its prevalence rising sharply in tandem with obesity and type 2 diabetes. While previously more common in Western nations, NASH is now becoming prevalent in developing countries adopting sedentary lifestyles and Western dietary habits. By 2030, NASH is expected to become the leading cause of liver transplants in the United States, underscoring the urgency to address it through early diagnosis, lifestyle interventions, and therapeutic advancements.
Risk Factors and Disease Progression
At the heart of NASH’s rise are modifiable lifestyle factors such as poor dietary choices, physical inactivity, and obesity, which contribute to insulin resistance and metabolic dysfunction. NASH is most common among individuals with type 2 diabetes, obesity, high cholesterol, and hypertension. However, the disease often progresses silently, with many patients remaining asymptomatic until advanced stages—when liver scarring or cirrhosis has already developed. This makes early detection and management crucial to slowing disease progression.
Diagnostic Challenges
One of the main barriers to combating NASH is early detection. Since the disease is asymptomatic in its early stages, it often goes unnoticed until patients show signs of severe liver damage. Currently, the most accurate diagnostic tool is liver biopsy, but its invasive nature limits its use for routine screening. Non-invasive techniques, such as elastography and serum biomarkers, are gaining traction and offer promise for identifying NASH earlier, but widespread access to these tools remains limited. A key priority for healthcare providers is developing affordable and accessible diagnostic methods to catch NASH before it advances to irreversible stages.
Addressing the Lack of Approved Treatments
Despite the growing burden of NASH, no approved pharmacological treatments are available. Current management strategies focus on lifestyle modifications, such as weight loss, healthy eating, and exercise, which have shown to improve liver health and slow disease progression. However, these interventions are difficult to maintain, particularly for patients with chronic conditions like diabetes or obesity. The pharmaceutical industry is actively exploring new therapies targeting inflammation, fibrosis, and metabolic dysfunction, with several promising candidates in clinical trials. Combination therapies that address multiple disease mechanisms are also being investigated to improve outcomes.
Prevention as a Key Strategy
Since NASH is closely tied to lifestyle factors, prevention is essential in reducing the disease burden. Public health campaigns promoting weight management, healthy eating, and physical activity are critical to combating the root causes of NASH. Education and awareness programs can also empower patients to adopt healthier lifestyles and seek medical advice early if they are at risk. Preventive strategies must particularly focus on high-risk populations, including individuals with obesity, diabetes, and metabolic syndrome, to reduce the incidence of NASH.
Innovations on the Horizon
The next decade is poised to bring significant advancements in the fight against NASH. Ongoing research is focused on anti-fibrotic drugs, metabolic modulators, and novel liver-protective therapies. Non-invasive diagnostic tools, such as MRI-based technologies and multi-marker panels, are improving the ability to detect and monitor NASH early, allowing for personalized treatment strategies. As the pharmaceutical pipeline advances, early intervention, and combination therapies may become the gold standard in NASH management.
The Role of Collaboration in Combating NASH
Successfully addressing the NASH epidemic requires collaborative efforts across healthcare providers, pharmaceutical companies, researchers, and policymakers. Governments must allocate resources for research funding and public health initiatives to ensure that new therapies and diagnostic tools are developed and accessible. Additionally, partnerships between advocacy groups, medical professionals, and community organizations can raise awareness about NASH and its associated risks. Integrating NASH screening into routine care for at-risk populations, such as patients with obesity or type 2 diabetes, will also be essential in curbing the disease’s rise.
Conclusion
NASH has transitioned from a lifestyle-driven disease to a public health crisis, with its prevalence reaching epidemic proportions. As obesity, diabetes, and metabolic disorders continue to rise, so too will the burden of NASH unless proactive measures are taken. Although challenges remain—particularly in terms of diagnosis and treatment—advances in research, diagnostics, and prevention offer hope for improved patient outcomes. Bridging the gap between lifestyle intervention and epidemic management will require a multifaceted approach, including innovative therapies, early detection tools, and collaborative public health efforts. Only through comprehensive strategies can we slow the progression of NASH and move toward better liver health worldwide.

Reading And Interpreting Your Liver Function Test - A Guide To Commonly Used Liver Tests
The liver is a vital organ responsible for numerous metabolic functions in the body, including detoxification, protein synthesis, and bile production. Monitoring liver health is crucial for early detection and management of liver diseases. One of the primary tools for assessing liver function is the Liver Function Test (LFT). In this guide, we will delve into the commonly used liver tests, how to interpret the results, and what they indicate about your liver health.
Understanding Liver Function Tests
Liver Function Tests (LFTs) are a group of blood tests that provide valuable insights into the health and function of the liver. These tests measure various enzymes, proteins, and substances in the blood that are indicative of liver health.
Key components of Liver Function Tests
Alanine Aminotransferase (ALT): Elevated levels suggest liver damage, commonly caused by conditions like hepatitis or fatty liver disease.
Aspartate Aminotransferase (AST): Similar to ALT, elevated AST levels indicate liver damage but may also be elevated in conditions affecting the heart or muscles.
Alkaline Phosphatase (ALP): Elevated ALP levels may suggest liver or bone disease.
Total Bilirubin: Increased levels may indicate liver dysfunction or obstruction of bile ducts.
Albumin and Total Protein: These are measures of liver synthetic function; decreased levels may suggest liver disease.
What are the causes of abnormal liver function test results?
Causes of abnormal liver function test results can vary and may indicate different underlying conditions. Some common causes include:
1. Build-up of Fat in the Liver:
* Non-alcoholic fatty liver disease (NAFLD) can lead to abnormal liver function tests, especially in overweight or obese individuals.
2. Liver Inflammation and Damage:
* Infections, toxic substances like alcohol or certain medications, and immune conditions can cause liver inflammation and subsequent abnormal test results.
3. Liver Overworking:
* When the liver is under stress from processing medicines or toxic substances like alcohol or paracetamol, it can result in abnormal liver function tests.
4. Bile Duct Blockage:
* Blockages in the bile ducts, such as by gallstones, can lead to abnormal liver function test results.
5. Liver Conditions and Diseases:
* Underlying conditions like Wilson's disease, haemochromatosis, or Gilbert's syndrome can affect liver function and result in abnormal test values.
6. Liver Injury:
* Physical injury to the liver, trauma, or presence of abscesses or tumors within the liver can cause abnormal liver function tests.
7. Medications and Supplements:
* Certain medications, over-the-counter drugs, herbal remedies, and traditional medicines can also impact liver function test results.
8. Other Factors:
* Factors like high alcohol intake, viral infections, autoimmune conditions, metabolic liver diseases, heart problems, and tumors in the liver can contribute to abnormal liver function tests.

An interesting study of diversity of covid biomarkers and what it could mean for future research
Introduction: Over the past four years, the COVID-19 pandemic has posed serious global health challenges. The severe form of disease and death resulted from the failure of immune regulatory mechanisms, closely highlighted by the dual proinflammatory cytokine and soluble immune checkpoint (sICP) storm. Identifying the individual factors impacting on disease severity, evolution and outcome, as well as any additional interconnections, have become of high scientific interest.
Methods: In this study, we evaluated a novel panel composed of ten sICPs for the predictive values of COVID-19 disease severity, mortality and Delta vs. Omicron variant infections in relation to hyperinflammatory biomarkers. The serum levels of sICPs from confirmed SARS-CoV-2 infected patients at hospital admission were determined by Luminex, and artificial neural network analysis was applied for defining the distinct patterns of molecular associations with each form of disease: mild, moderate, and severe.
Results: Notably, distinct sICP profiles characterized various stages of disease and Delta infections: while sCD40 played a central role in all defined diagrams, the differences emerged from the distribution levels of four molecules recently found and relatively less investigated (sCD30, s4-1BB, sTIM-1, sB7-H3), and their associations with various hematological and biochemical inflammatory biomarkers. The artificial neural network analysis revealed the prominent role of serum sTIM-1 and Galectin-9 levels at hospital admission in discriminating between survivors and non-survivors, as well as the role of specific anti-interleukin therapy (Tocilizumab, Anakinra) in improving survival for patients with initially high sTIM-1 levels. Furthermore, strong associations between sCD40 and Galectin-9 with suPAR defined the Omicron variant infections, while the positive match of sCD40 with sTREM-1 serum levels characterized the Delta-infected patients.
Conclusions: Of importance, this study provides a comprehensive analysis of circulatory immune factors governing the COVID-19 pathology, and identifies key roles of sCD40, sTIM-1, and Galectin-9 in predicting mortality.

Quantitative site-specific glycoproteomics by ZenoTOF reveals glyco-signatures for breast cancer diagnosis
Intact glycopeptide characterization by mass spectrometry has proven a versatile tool for site-specific glycoproteomics analysis and biomarker screening. Here, we present a method using the ZenoTOF instrument with optimized fragmentation for intact glycopeptide identification and demonstrate its ability to analyze large-cohort glycoproteomes. From 124 clinical serum samples of breast cancer, non-cancerous diseases, and non-disease controls, a total of 6901 unique site-specific glycans on 807 glycosites of proteins were detected. Much more differences of glycoproteome were observed in breast diseases than the proteome. By employing machine learning, 15 site-specific glycans were determined as potential glyco-signatures in detecting breast cancer. The results demonstrate that our method provides a powerful tool in glycoproteomic analyses for biomarker discovery studies. http://dlvr.it/TD371G
