#DietaryNitrate #SportsPerformance #DietarySupplementation #NutritionAndSport
Physical activity is essential for maintaining both physical and mental health. However, it presents several challenges, especially during high-intensity efforts. Sprints, for instance, place significant demands on muscles, particularly Type II fibers, which are responsible for rapid and powerful contractions. These fibers, however, fatigue quickly due to lactic acid buildup and limited oxygen supply, leading to a decline in performance. Additionally, the efficiency of muscle contractions and optimal distribution of nutrients and oxygen to muscles are often limiting factors, even for well-trained athletes.
In this context, dietary supplementation has emerged as a promising solution to push these boundaries. Among the options studied, dietary nitrate, commonly consumed as concentrated beetroot juice, has garnered particular attention due to its unique physiological properties. Metabolized into nitric oxide (NO) in the body, nitrate enhances vasodilation, improving blood flow to active muscles. Furthermore, it acts directly on intracellular mechanisms, optimizing calcium release in muscle fibers, which enhances contraction efficiency.
This article explores the impact of dietary nitrate on high-intensity sprint performance, focusing specifically on its effectiveness in 30-second tests. The aim is to assess how supplementation can mitigate the physiological limitations inherent to explosive efforts and improve athletic outcomes.
The studies revealed that dietary nitrate supplementation could have a significant impact on certain aspects of sprint performance. Notably, there was an improvement in the time required to reach peak power. Participants who received a low dose of nitrate in an acute form showed a significant reduction in this parameter. Conversely, moderate doses administered over several days did not produce significant effects. This suggests that nitrate’s effectiveness may be more pronounced in acute, low-dose usage.
Regarding average and peak power, no significant effects were observed, indicating that dietary nitrate does not directly enhance overall sprint performance metrics. However, nitrate appears particularly beneficial during the initial phases of sprints, specifically during acceleration. This implies that its action may be related to optimizing muscle efficiency and responsiveness in the first few seconds of intense effort.
Further research is needed to explore the effectiveness of dietary nitrate in elite athletes. Another area of interest would be to study differences in response between men and women. Identifying optimal supplementation protocols in terms of dosage and frequency also represents an intriguing avenue. These advances could enable more targeted integration of dietary nitrate into training programs, offering a promising strategy for improving performance during high-intensity exercises.

Nitrate: A Performance Accelerator?
A total of six studies were included in the analysis, involving 88 participants aged 21 to 27 years, all recreationally active. The interventions consisted of dietary nitrate administration in the form of beetroot juice, with low doses (5.6 to 8.2 mmol) or moderate doses (11.2 to 13 mmol). These doses were tested over varying durations, from a single intake to several consecutive days of supplementation.The studies revealed that dietary nitrate supplementation could have a significant impact on certain aspects of sprint performance.

#Alcohol #Depression #AlcoholUseDisorder #Addiction #Relapse #MentalHealth #HealthManagement
Alcohol use disorder (AUD) is a complex condition affecting millions of people worldwide, with profound consequences on both mental and physical health. Among the commonly associated comorbidities, depressive symptoms play a central role, significantly impacting patients' quality of life and their ability to maintain long-term abstinence. These depressive symptoms also increase the risk of relapse, creating a challenging vicious cycle to break.
While alcohol abstinence generally leads to an improvement in depressive symptoms due to reduced neurotoxic effects of alcohol on the brain, some patients continue to experience depression even after several weeks without drinking. This phenomenon raises important questions about the factors contributing to the persistence of depressive disorders in this population.
This study aims to better understand these mechanisms by exploring the link between pre-abstinence drinking behaviors and the persistence of depressive symptoms after four weeks of abstinence.
Drinking behaviors were assessed using the DBP-20 questionnaire, which measures factors such as automaticity, social use, and reliance on alcohol to manage negative emotions. Advanced statistical analyses, including logistic regression and ROC curves, were used to identify predictors of persistent depression.
The findings demonstrated that patients who used alcohol as a strategy to cope with negative emotions had a significantly higher risk of persistent depression after abstinence. High scores on the "coping with negative emotions" subscale were associated with elevated rates of depression, particularly among unemployed patients. Conversely, patients with automatic drinking habits showed more frequent natural remission, suggesting that their depressive symptoms were more alcohol-induced.
Identified risk factors include:
The results also highlight the importance of offering therapeutic alternatives, such as cognitive-behavioral therapies, to help these patients manage their emotions without relying on alcohol.
This study explored the role of drinking behaviors in the persistence of depressive symptoms after four weeks of abstinence. The findings underscore that using alcohol as an emotional coping mechanism is a key factor contributing to persistent symptoms. These conclusions emphasize the importance of assessing the underlying motivations for alcohol use to tailor therapeutic strategies to patients' needs.
However, the study has limitations, including a small sample size and the lack of long-term follow-up, which prevent generalization of the results. Larger-scale research with diverse cohorts and extended follow-ups is necessary. Enhancing rehabilitation programs by combining psychosocial therapies and tools like the DBP-20 could better identify at-risk patients. A personalized approach could reduce persistent depression and prevent relapse, providing more comprehensive and effective care.

Alcohol: A Double-Edged Escape?
A total of 102 patients with initial depressive symptoms (QIDS-SR-J score ≥ 6) hospitalized for AUD were included in the study. After four weeks of abstinence, participants were divided into two groups:- Remission group (51 patients): No persistent depressive symptoms.
- Persistence group (51 patients): Persistent depressive symptoms.
Drinking behaviors were assessed using the DBP-20 questionnaire, which measures factors such as automaticity, social use, and reliance on alcohol to manage negative emotions.

#AnxietyDisorder #Depression #MindfulMeditation #Antidepressant #Escitalopram #MentalHealth
Anxiety disorders are among the most common mental health conditions, affecting millions worldwide. These disorders, which include generalized anxiety disorder, panic disorder, and agoraphobia, significantly impact individuals' quality of life by disrupting their well-being, sleep, social relationships, and daily functioning.
Antidepressants like Escitalopram are frequently prescribed as a first-line treatment to alleviate these symptoms. These medications have proven effective in managing anxiety by targeting neurotransmitters involved in mood regulation. However, their use is often limited by undesirable side effects, such as gastrointestinal issues, headaches, or weight gain, which can result in poor treatment adherence.
Given these limitations, Mindfulness-Based Stress Reduction (MBSR) has emerged as a promising complementary or alternative approach. This method combines guided meditation, body awareness, and stress reduction techniques, offering a non-invasive and side effect-free strategy that empowers patients to manage their anxiety.
This study compares the effectiveness of MBSR with standard treatment using Escitalopram for major anxiety disorders.
A total of 276 adult participants diagnosed with anxiety disorders were randomly assigned to two groups:
Outcomes were assessed at 8 weeks, then at 12 and 24 weeks, using a mixed-model analysis adjusted for baseline demographic and clinical factors.
Both treatments demonstrated significant reductions in anxiety and depressive symptoms. Anxiety scores decreased comparably across the groups, confirming that MBSR is non-inferior to standard treatment. However, Escitalopram showed a faster improvement during the initial weeks.
A key finding was the difference in side effects: 78.6% of patients on Escitalopram reported treatment-related adverse events, compared to only 15.4% in the MBSR group. This highlights a significant advantage of mindfulness meditation, particularly for patients seeking better-tolerated alternatives.
Anxiety disorders significantly affect patients' quality of life. While pharmacological treatments like Escitalopram are effective, their side effects often reduce adherence and satisfaction with care.
This study aimed to compare the effectiveness of MBSR with Escitalopram in treating anxiety disorders, while also evaluating their respective tolerability and benefits on anxiety, depression, and quality of life.
The results show that MBSR is as effective as Escitalopram in reducing anxiety symptoms, with a markedly superior safety profile. Participants in the mindfulness program reported significantly fewer side effects, making MBSR an appealing option for patients who are sensitive to or reluctant to take medications.
Further research should explore models for integrating MBSR into healthcare systems. Additionally, studies on larger cohorts with extended follow-ups are needed to confirm these findings and better understand the overall impact of meditation on mental health. These efforts could transform the management of anxiety disorders by offering a viable, safe, and effective non-pharmacological alternative.

Meditation or Medication: Which Comes Out on Top?
Researchers evaluated both treatments based on anxiety, depression, and quality of life metrics, using validated clinical tools such as the Beck Anxiety Inventory (BAI) and PROMIS Anxiety Short Form. Symptom severity was measured in a standardized manner to ensure comparability across groups.A total of 276 adult participants diagnosed with anxiety disorders were randomly assigned to two groups:
- MBSR: Eight weeks of weekly guided meditation sessions and practice.
- Escitalopram: Flexible dosing (10-20 mg/day) with regular medical follow-up.
Outcomes were assessed at 8 weeks, then at 12 and 24 weeks, using a mixed-model analysis adjusted for baseline demographic and clinical factors.
Both treatments demonstrated significant reductions in anxiety and depressive symptoms. Anxiety scores decreased comparably across the groups, confirming that MBSR is non-inferior to standard treatment. However, Escitalopram showed a faster improvement during the initial weeks.

Adolescent depression is a major global health concern. According
to the WHO, approximately 14% of young people suffer from mental disorders,
with depression being the second leading cause of morbidity in this age group.
This issue was exacerbated by the COVID-19 pandemic, which led to increased
feelings of isolation, sadness, and anxiety. The relationship between lifestyle
and mental health is being increasingly studied, particularly the impact
of physical activity as a non-pharmacological approach to managing depressive
symptoms.
Physical activity has a positive effect by regulating hormones like serotonin and dopamine, which influence mood, sleep, and motivation. It also provides social and psychological benefits, enhancing self-esteem and fostering interpersonal connections. Despite these clear advantages, many adolescents remain sedentary, which worsens the risk of depression.
This review explores recent scientific evidence on the impact of physical activity in reducing depressive symptoms among young people.
The findings show that regular physical activity significantly reduces depressive symptoms. Adolescents participating in team sports or engaging in moderate physical activity demonstrate improved mental health. Self-esteem, enhanced through physical activity, plays a crucial role as a mediator: the higher the self-esteem, the lower the depressive symptoms.
However, excessive physical activity can have negative effects, including an increased risk of injuries or burnout. Adolescents involved in highly competitive sports also reported higher stress levels. Moreover, sedentary behaviors, such as prolonged screen time, substantially diminish the benefits of physical activity on depressive symptoms, emphasizing the importance of balancing movement and rest.
The study aimed not only to explore the impact of physical activity on reducing depressive symptoms but also to highlight the underlying mechanisms, such as improved self-esteem and reduced sedentary behaviors. The findings confirm that regular physical activity plays a positive role in alleviating depressive symptoms.
However, the study reveals several limitations. The effectiveness of physical activity depends on its frequency, intensity, and context. Excessive activity can lead to negative effects, such as stress or injuries. Prolonged screen time reduces the benefits of physical activity. Additionally, data on long-term effects or variations related to gender and culture remain limited.
Future research is needed to better understand these complex interactions. Intervention programs should promote balanced and appropriate physical activity, targeting sedentary behaviors and incorporating accessible and motivating activities for young people. By integrating these strategies into public health policies, it may be possible to reduce the prevalence of depression among adolescents and sustainably improve their mental health.

Major Depressive Disorder
(MDD) is one of the leading causes of disability worldwide, significantly
impacting the quality of life for millions. Affecting approximately 322 million
individuals globally, it represents a substantial burden for both individuals
and healthcare systems. In some European countries, its prevalence can reach up
to 21%, underscoring the widespread nature of this condition.
This is particularly true because MDD is a complex and heterogeneous disease, characterized by a wide variety of symptoms and clinical trajectories. This variability makes treatment especially challenging, as nearly 30% of patients do not respond to traditional therapies (antidepressants, psychotherapy). These cases of treatment-resistant depression call for an urgent exploration of alternative therapeutic solutions targeting biological mechanisms not addressed by current treatments.
This article reviews emerging treatments for MDD, examining pharmacological advancements (psychedelics, anti-inflammatory agents) and neuromodulatory approaches (transcranial magnetic stimulation, photobiomodulation). The goal is to provide an analysis of their efficacy, mechanisms of action, and clinical applicability, paving the way for new options for patients unresponsive to conventional therapies.
Emerging treatments for MDD include a variety of promising approaches. Among psychedelics, ketamine and its derivative, esketamine, stand out for their rapid effects on depression and suicidal ideation. However, their long-term efficacy remains uncertain, and ketamine raises concerns about dependency. Psilocybin, combined with psychological support, also shows encouraging results, though intensive monitoring is required due to potential side effects.
Anti-inflammatory agents, such as minocycline, statins, and omega-3 fatty acids, have demonstrated significant reductions in depressive symptoms when used as adjuncts to traditional treatments. Additionally, the buprenorphine-samidorphan combination, an opioid-based treatment, has been well-tolerated and effective in alleviating symptoms, offering new pharmacological possibilities.
Lastly, alternative treatments, such as onabotulinumtoxinA, have shown antidepressant potential despite an unclear mechanism of action.
Light therapy and photobiomodulation show promise when used alongside other treatments. These techniques influence circadian rhythms and mood regulation, though their precise mechanisms require further investigation.
More invasive options, such as deep brain stimulation and magnetic seizure therapy, provide effective alternatives for patients with treatment-resistant depression. However, their use remains limited due to risks, high costs, and procedural complexity. Despite these challenges, these advances hold considerable potential for improving the management of treatment-resistant depression.

Snoring and Triglycerides: A Surprising Association
General Medicine Endocrinology and Metabolism
Sleep disturbances and metabolic imbalances are closely linked to mental
health, particularly depression. Sleep, which is essential for physical and
psychological well-being, is often disrupted in individuals suffering from
depression. These disruptions can manifest as insomnia, hypersomnia, or sleep
apnea. The relationship between depression and sleep is bidirectional: poor
sleep quality exacerbates depressive symptoms, while depression disrupts
circadian rhythms and sleep patterns.
Read next: The use of acupuncture as a complementary treatment for sleep disorders
Snoring, often dismissed as a mere nighttime nuisance, may play a role in this interaction. It reflects respiratory abnormalities and periods of intermittent hypoxia, which are associated with oxidative stress and systemic inflammation. These biological mechanisms not only contribute to depression but also to metabolic imbalances, such as elevated triglyceride levels—a cardiovascular marker.
This study explores the relationship between snoring, triglycerides, and metabolic disorders, aiming not only to establish a connection but also to better understand the broader impact of sleep disorders on mental and physical health.
The results indicate that snoring, whether occasional or habitual, is significantly associated with increased triglyceride levels. Participants who snored occasionally showed moderate increases in triglyceride levels, while habitual snorers exhibited even higher levels. In contrast, rare snoring was not significantly associated with elevated triglycerides.
Interestingly, the frequency of snoring was closely linked to metabolic imbalance, independent of BMI. Subgroup analyses revealed that the association between snoring and triglycerides was present in individuals with normal BMI, as well as in those who were overweight or obese. These findings underscore that snoring is more than just an auditory disturbance; it may also serve as a potential indicator of metabolic and cardiovascular risks, emphasizing the need for early intervention.
This study aimed to explore the link between snoring frequency and triglyceride levels, accounting for factors such as BMI. The results demonstrate a significant association: frequent snoring correlates with elevated triglyceride levels, independent of BMI, highlighting its potential role as an indicator of metabolic imbalances.
However, limitations persist. Criteria for defining different types of snoring vary between studies, potentially introducing heterogeneity in the results. Further research, using more precise measurement tools and larger sample sizes, is necessary to confirm these findings. Integrating snoring into screening strategies could open new avenues for preventing metabolic risks and improving overall health.

This study explores the relationship between snoring, triglycerides, and metabolic disorders, aiming not only to establish a connection but also to better understand the broader impact of sleep disorders on mental and physical health.
How Does Snoring Affect Metabolism?
Five studies, including 39,102 participants, were selected and analyzed. Participants were categorized based on the frequency of their snoring (rare, occasional, habitual). Triglyceride levels were compared between snorers and non-snorers, with adjustments made for body mass index (BMI).The results indicate that snoring, whether occasional or habitual, is significantly associated with increased triglyceride levels. Participants who snored occasionally showed moderate increases in triglyceride levels, while habitual snorers exhibited even higher levels. In contrast, rare snoring was not significantly associated with elevated triglycerides.
Interestingly, the frequency of snoring was closely linked to metabolic imbalance, independent of BMI.

These findings underscore that snoring is more than just an auditory disturbance; it may also serve as a potential indicator of metabolic and cardiovascular risks, emphasizing the need for early intervention.
Snoring: A Metabolic Marker to Monitor
Snoring, often perceived as a mere annoyance, may have significant effects on metabolic and mental health. This phenomenon, associated with intermittent hypoxia episodes and systemic inflammation, contributes to metabolic imbalances that are largely underestimated. Identifying and managing the metabolic risks associated with snoring represents a significant challenge.This study aimed to explore the link between snoring frequency and triglyceride levels, accounting for factors such as BMI. The results demonstrate a significant association: frequent snoring correlates with elevated triglyceride levels, independent of BMI, highlighting its potential role as an indicator of metabolic imbalances.

Treatment-resistant depression (TRD) is a severe form of depression that
persists despite the use of at least two adequate antidepressant treatments.
This condition, affecting approximately one-third of depressed patients,
represents a significant challenge in psychiatry. TRD is associated with
significantly reduced quality of life, increased risk of comorbidities,
including anxiety and cardiovascular diseases, and higher mortality rates.
Despite the benefits of current treatments, their effectiveness remains limited for these patients, highlighting an urgent need for alternative solutions. These new approaches must target biological mechanisms often overlooked by conventional treatments while offering innovative and personalized options.
In this context, the ketogenic diet emerges as a promising avenue to complement or enhance conventional therapies. Known for its neuroprotective effects and its beneficial impact on gut microbiota, this diet—based on low carbohydrate and high fat consumption—stimulates the production of ketone bodies. These molecules play a crucial role in regulating brain functions by improving neuronal balance, reducing oxidative stress, and modulating inflammatory processes.
This study explores the efficacy and mechanisms of the ketogenic diet as a complementary treatment for treatment-resistant depression.
Read next: Winter Blues: How Lifestyle Makes the Difference
The study lasted six weeks, with rigorous follow-up to evaluate participant adherence. Depressive symptoms were assessed at 6 and 12 weeks. Secondary parameters included anxiety, quality of life, reward sensitivity, and changes in gut microbiota.
Participants following the ketogenic diet showed a significant reduction in depression scores at six weeks compared to the control group. Improvements were also observed in secondary aspects such as anxiety and anhedonia.
The data also suggest that the ketogenic diet influences several biological mechanisms. It stimulates the production of the neurotransmitter GABA, essential for the balance between neuronal excitation and inhibition, thereby reducing brain dysfunctions associated with depression. Ketone bodies produced by this diet exert protective effects against oxidative stress. Beneficial changes in gut microbiota were also observed, promoting the growth of bacteria linked to better mental health.
Faced with these challenges, the ketogenic diet appears as an innovative approach, targeting biological mechanisms such as neurotransmitter balance, oxidative stress reduction, and gut microbiota improvement. This study aimed to evaluate its efficacy and potential as a complementary treatment by comparing a ketogenic diet group with a control group receiving a more conventional diet.
The results show that the ketogenic diet significantly improves depressive symptoms, particularly anxiety and anhedonia. However, its impact depends on strict adherence, which poses a significant challenge for its clinical implementation.
Larger-scale studies with extended follow-up are necessary to confirm these findings and identify strategies to enhance patient adherence. If these obstacles are overcome, the ketogenic diet could expand current therapeutic options, offering a promising new path for patients with TRD.

The Ketogenic Diet: A Remedy That Lives Up to Its Promises?
In this study, patients aged 18 to 65 with TRD were randomly divided into two groups:- Ketogenic Diet Group (KD): Carbohydrate intake limited to 30g per day, with meals prepared and weekly monitoring by a dietitian. Ketosis levels were regularly measured to assess adherence.
- Control Group (Plant-Based Diet): Similar monitoring but based on a diet richer in vegetables and unsaturated fats.
The study lasted six weeks, with rigorous follow-up to evaluate participant adherence. Depressive symptoms were assessed at 6 and 12 weeks. Secondary parameters included anxiety, quality of life, reward sensitivity, and changes in gut microbiota.
Participants following the ketogenic diet showed a significant reduction in depression scores at six weeks compared to the control group. Improvements were also observed in secondary aspects such as anxiety and anhedonia.
The data also suggest that the ketogenic diet influences several biological mechanisms. It stimulates the production of the neurotransmitter GABA, essential for the balance between neuronal excitation and inhibition, thereby reducing brain dysfunctions associated with depression. Ketone bodies produced by this diet exert protective effects against oxidative stress. Beneficial changes in gut microbiota were also observed, promoting the growth of bacteria linked to better mental health.
The Ketogenic Diet: A Revolution in Progress
TRD is a severe form of depression that persists despite the use of antidepressants. Affecting about one-third of depressed patients, it leads to reduced quality of life and increased risks of comorbidities.Faced with these challenges, the ketogenic diet appears as an innovative approach, targeting biological mechanisms such as neurotransmitter balance, oxidative stress reduction, and gut microbiota improvement. This study aimed to evaluate its efficacy and potential as a complementary treatment by comparing a ketogenic diet group with a control group receiving a more conventional diet.
The results show that the ketogenic diet significantly improves depressive symptoms, particularly anxiety and anhedonia. However, its impact depends on strict adherence, which poses a significant challenge for its clinical implementation.
Larger-scale studies with extended follow-up are necessary to confirm these findings and identify strategies to enhance patient adherence. If these obstacles are overcome, the ketogenic diet could expand current therapeutic options, offering a promising new path for patients with TRD.
Depression and Seasonal Affective Disorder (SAD) are among the most
common and debilitating mood disorders, affecting millions of people worldwide.
Depression alone impacts approximately 280 million individuals, significantly
reducing quality of life, decreasing productivity, and increasing the risk of
comorbidities. SAD, on the other hand, is a specific type of depression that
occurs primarily during winter when exposure to natural light decreases,
causing symptoms such as low mood, persistent fatigue, and hypersomnia.

Although these disorders are influenced by genetic, environmental, and psychological factors, they are also linked to nutritional deficiencies, particularly in micronutrients like vitamins B, C, and D. These vitamins play a crucial role in brain function by enabling neurotransmitter synthesis (serotonin and dopamine) and regulating inflammatory and oxidative processes. Deficiencies in these vitamins have been associated with worsening depressive symptoms and increased prevalence of SAD.
This study explores the role of water-soluble vitamins (B and C) and vitamin D in the prevention and treatment of depression and SAD.

The effectiveness of supplementation on depressive symptoms was measured at baseline and post-intervention using validated scales (Beck and Hamilton scales).
Vitamin B, particularly B12 and B9, proved effective in reducing depressive symptoms, especially among individuals with initial deficiencies. Regular supplementation improved mood and reduced mental fatigue. Vitamin C, with its antioxidant action and role in neurotransmitter synthesis, also demonstrated improvements in depressive scores, although the data remain limited.
Regarding vitamin D, the results were mixed. While some studies showed significant improvement in SAD symptoms following daily supplementation, others observed no major difference compared to the placebo. Variations in administered doses and intervention durations may explain these discrepancies. However, vitamin D remains associated with a reduced risk of depression in deficient individuals.
Vitamins B, C, and D play a key role in mood regulation, neurotransmitter synthesis, and oxidative stress management. This study aimed to evaluate their impact on depressive symptoms and SAD by comparing the effectiveness of their supplementation to a placebo. The results, while promising, indicate symptom improvements, particularly among individuals with initial deficiencies.
However, the study has limitations, including small sample sizes, heterogeneous protocols (doses, durations), and inconsistent results across trials. These factors limit the generalizability of the findings and highlight the need for more rigorous research.
In the future, large-scale studies with standardized methodologies and long-term follow-up are essential to clarify mechanisms of action and establish precise recommendations. Incorporating these micronutrients into nutritional strategies could provide affordable and accessible solutions, contributing to improved global mental health management.

Seasonal Affective Disorder (SAD) is a type of depression that primarily
occurs in autumn and winter, when exposure to natural light decreases. This
lack of light disrupts the internal biological clock, or circadian rhythm,
which regulates sleep and hormone production, including serotonin and
melatonin. A decrease in serotonin is linked to depressive states, while an
excess of melatonin, exacerbated by the lack of light, can lead to excessive
sleepiness. These imbalances result in typical SAD symptoms, such as low mood,
persistent fatigue, increased need for sleep, cravings for carbohydrates, and
weight gain—symptoms that significantly affect the quality of life and daily
activities of those affected.
To address these imbalances, light therapy has emerged as an effective and popular solution. This method involves exposing patients to intense artificial light that mimics natural sunlight and is rich in the light spectrum. By directly influencing the reactivation of the circadian rhythm, light therapy helps restore disrupted biological cycles. It also stimulates serotonin production and regulates melatonin levels, thereby improving mood, reducing fatigue, and normalizing sleep patterns. Due to its demonstrated efficacy and simplicity of use, light therapy has become a leading treatment option for individuals with SAD.
Initial trials demonstrate that high-intensity morning light therapy—30 minutes per day for six weeks—is associated with a significant improvement in mood and a reduction in depressive symptoms. Similarly, medium-intensity light therapy—45 minutes per day for four weeks—showed a decrease in depressive symptoms, though the effects were less pronounced. A meta-analysis of 10 studies confirmed that light therapy is significantly more effective than placebo in reducing depressive symptoms in patients with SAD.
This study aimed to evaluate the effectiveness of light therapy on depressive symptoms associated with SAD. The findings reveal that light therapy, particularly when administered in the morning, significantly reduces symptoms compared to placebo. These conclusions, supported by a meta-analysis of 10 randomized controlled trials (RCTs), establish light therapy as a promising, non-invasive, and safe method for treating SAD.

However, limitations remain. The effectiveness of light therapy depends on factors such as intensity, duration, and timing of exposure. Barriers such as the cost of devices and the consistency of sessions may also hinder its adoption. Future research with larger samples and long-term follow-up is needed to better understand its impact and to develop broader clinical recommendations, thereby facilitating the integration of this method into comprehensive SAD management.

When Light Defeats the Blues: Proven Effectiveness
This study investigates the effect of light therapy on depressive symptoms in patients with SAD. To this end, a group receiving light therapy was compared to a control group receiving either a placebo (exposure to low-intensity light) or standard treatment. Depressive symptoms were measured at various stages—before the start of treatment, during the intervention, and after—to evaluate progress over time. These assessments were conducted using validated and recognized clinical scales, such as the Beck Depression Inventory and the Hamilton Depression Rating Scale, ensuring the reliability and comparability of results.Initial trials demonstrate that high-intensity morning light therapy—30 minutes per day for six weeks—is associated with a significant improvement in mood and a reduction in depressive symptoms. Similarly, medium-intensity light therapy—45 minutes per day for four weeks—showed a decrease in depressive symptoms, though the effects were less pronounced. A meta-analysis of 10 studies confirmed that light therapy is significantly more effective than placebo in reducing depressive symptoms in patients with SAD.
Illuminating the Future of SAD: A Promising Solution
SAD is a form of depression caused by the lack of light in winter, leading to debilitating symptoms such as fatigue, low mood, and sleep disturbances. This condition significantly impacts quality of life and requires effective treatments to mitigate its effects.This study aimed to evaluate the effectiveness of light therapy on depressive symptoms associated with SAD.

Seasonal Affective Disorder (SAD) is a form of recurrent depression
linked to seasonal changes, particularly in autumn and winter when daylight
decreases. Symptoms include persistent fatigue, loss of energy, increased need
for sleep, strong cravings for carbohydrates, weight gain, and reduced
motivation or interest in daily activities. In severe cases, it may even lead
to feelings of hopelessness or social withdrawal.
The primary causes include a disruption of the circadian rhythm caused by a lack of natural light, leading to dysregulation in the production of melatonin and serotonin—key hormones in mood and sleep regulation. Abnormalities in monoaminergic systems, which modulate dopamine and norepinephrine, as well as genetic predisposition, may also play a significant role in the development of SAD.
While traditional treatments such as light therapy, antidepressants, and psychotherapy are effective, they are not suitable for everyone. Lifestyle modifications, including a balanced diet, regular physical activity, exposure to natural light, or stress management techniques, are gaining popularity as alternatives or complementary approaches.

Limited Evidence of Effectiveness. While improvements in depression scores were observed in both intervention and control groups, these results remain unreliable. Small sample sizes (18 to 61 participants) and high risks of methodological bias significantly limit the robustness and generalizability of the findings.
Dietary Modifications. Studies on carbohydrate-rich diets showed a reduction in depressive symptoms; however, these effects were not significantly greater than those observed with a placebo. No clear recommendations regarding the role of diet in managing SAD could be established.
Physical Exercise and Outdoor Exposure. Exercise programs, such as daily physical activity under bright light, led to a significant reduction in depression scores, comparable to light therapy. Exposure to natural outdoor light also showed beneficial effects. However, methodological limitations persist.
Other Interventions. Promising results were noted for music therapy and sleep deprivation-based interventions. Nevertheless, the data remain insufficient to form solid recommendations.
This study aimed to assess the effectiveness of lifestyle modifications, such as diet, exercise, or outdoor exposure, in alleviating SAD symptoms. Although improvements in depression scores were observed, the findings indicate limited evidence of effectiveness due to small sample sizes and high risks of methodological bias. No definitive conclusions can be drawn about the actual impact of these interventions.
Despite these limitations, lifestyle-based interventions offer promising perspectives. Accessible, safe, and cost-effective, they could be helpful for patients hesitant to use medications or as complementary options alongside traditional treatments.

Diet, Exercise, and Light: What Do Studies Say?
This research explores the efficacy and safety of lifestyle interventions for managing SAD. Six studies focusing on dietary modifications (carbohydrate-rich diets), physical exercise, outdoor exposure, sleep, and mindfulness techniques (e.g., music therapy) were analyzed. The effectiveness of these interventions was measured by observing reductions in depressive symptoms using validated psychiatric scales, compared to a control group.Limited Evidence of Effectiveness. While improvements in depression scores were observed in both intervention and control groups, these results remain unreliable.

Revolutionizing SAD Management Through Lifestyle Choices
SAD is a common mental health issue that affects millions of people during autumn and winter. It leads to fatigue, depression, and behavioral changes, often linked to a disruption of the circadian rhythm. Exploring accessible and affordable solutions, alongside conventional treatments like light therapy or antidepressants, is essential to better support patients.This study aimed to assess the effectiveness of lifestyle modifications, such as diet, exercise, or outdoor exposure, in alleviating SAD symptoms. Although improvements in depression scores were observed, the findings indicate limited evidence of effectiveness due to small sample sizes and high risks of methodological bias. No definitive conclusions can be drawn about the actual impact of these interventions.

The Insulin-like Growth Factor 1 (IGF-1) and its binding proteins (IGFBPs) play
a key role in regulating cellular growth, apoptosis, and metabolic homeostasis.
Imbalances in their concentrations have been associated with serious conditions
such as cancer, cardiovascular diseases, and metabolic disorders. Identifying
modifiable factors influencing these biomarkers could provide new perspectives
in prevention strategies.
Among potential determinants, the role of low-fat diets remains controversial. While some studies suggest a decrease in IGF-1 and IGFBPs levels with reduced fat intake, others have observed no effect or even increases. These inconsistencies highlight an urgent need for a comprehensive synthesis and global analysis of existing data. This study explores the impact of low-fat diets on IGF-1 and IGFBP concentrations.
Low-fat diets showed no significant effect on IGF-1 levels, with a weighted mean difference (WMD) of 1.63 ng/ml. Analyses detected no heterogeneity among the included studies (I² = 0%), ensuring some consistency in the findings. Similarly, IGFBP-3 concentrations were not significantly influenced by these diets, with no heterogeneity observed (I² = 0%). However, data on IGFBP-1, limited to only two studies, yielded contradictory results, making any conclusions about this biomarker impossible.
The results indicate that low-fat diets are insufficient to effectively modulate these biomarkers to reduce the risk of severe diseases. However, interpreting the results is hindered by several limitations. Disparities among the analyzed studies (proportions and sources of macronutrients) complicate the establishment of clear links between diet and health. Other factors, such as body composition, age, physical activity, or micronutrient intake, may also influence the results.
This study underscores the need for more rigorous research that controls for confounding variables and explores underlying biological mechanisms to provide more targeted and scientifically substantiated nutritional recommendations.

Low-Fat Diets: Do They Really Affect Our Hormones?
This study, conducted on adults aged ≥18 years, compares the effects of low-fat diets (≤30% of energy intake) to standard or high-fat diets (>30%). The effects of these various diets were assessed by measuring IGF-1 and IGFBP concentrations before and after the intervention. Results were consolidated using a random-effects model, estimating weighted mean differences (WMDs) and their confidence intervals (CIs).Low-fat diets showed no significant effect on IGF-1 levels, with a weighted mean difference (WMD) of 1.63 ng/ml. Analyses detected no heterogeneity among the included studies (I² = 0%), ensuring some consistency in the findings.

However, data on IGFBP-1, limited to only two studies, yielded contradictory results, making any conclusions about this biomarker impossible.
Low-Fat Diets: The Expected Effect Falls Short!
Biomarkers such as IGF-1 and IGFBPs play a central role in regulating cell growth and metabolic processes. Strongly associated with an increased risk of cancers (breast, prostate, colon) and higher overall mortality, these markers are also major targets in strategies for preventing severe diseases. This study aimed to assess whether low-fat diets could influence the expression of these biomarkers.The results indicate that low-fat diets are insufficient to effectively modulate these biomarkers to reduce the risk of severe diseases.

Respiratory infections pose a major health challenge for older adults,
whose immune systems are often weakened, making these infections more severe
and potentially life-threatening. The two main seasonal viruses responsible are
respiratory syncytial virus (RSV) and the influenza virus.
RSV is a leading cause of severe respiratory illnesses, as is the flu, which can lead to serious complications, including pneumonia. Due to their vulnerability, adults aged 65 and older require enhanced protection against these infections.
The development of combination vaccines, allowing the simultaneous administration of two vaccines, offers an innovative and practical solution to improve vaccination rates in this population. This study examines the impact of co-administering a bivalent RSV vaccine (RSVpreF) with the inactivated influenza vaccine (SIIV) in adults aged 65 and older. The goal is to assess not only the safety and tolerance of this combination but also its immune effectiveness compared to separate administration of the two vaccines.
The primary objective was to compare the immune responses, efficacy, tolerance, and safety of co-administration. Key parameters studied included antibody titers against RSV and the flu, as well as local side effects (injection site pain) and systemic effects (fatigue, headaches).
The results showed that the co-administration of the two vaccines was safe and well-tolerated by participants. No vaccine-related serious adverse events were reported. Local and systemic side effects were primarily mild to moderate. Neutralizing antibody titers for RSV and hemagglutination inhibition (HAI) titers for the flu met predefined non-inferiority criteria. These findings indicate that the immune response to each vaccine, when administered together, is comparable to that achieved with separate administrations.
While these results propose co-administration as an effective and safe solution to protect older adults, future studies will need to evaluate the durability of these immune responses and confirm the impact of this approach on reducing severe respiratory illnesses in this population. Combining the two vaccines could transform the preventive management of respiratory infections in seniors, thereby improving their overall health.

The goal is to assess not only the safety and tolerance of this combination but also its immune effectiveness compared to separate administration of the two vaccines.
RSVpreF and flu vaccine: an effective solution for seniors?
In this study, 1,403 participants aged 65 and older were randomly assigned to two groups:- A group receiving both vaccines simultaneously (RSVpreF + SIIV);
- A group receiving the vaccines separately, 28 days apart.
The primary objective was to compare the immune responses, efficacy, tolerance, and safety of co-administration. Key parameters studied included antibody titers against RSV and the flu, as well as local side effects (injection site pain) and systemic effects (fatigue, headaches).
The results showed that the co-administration of the two vaccines was safe and well-tolerated by participants. No vaccine-related serious adverse events were reported.

These findings indicate that the immune response to each vaccine, when administered together, is comparable to that achieved with separate administrations.
Double vaccine, double protection
This study suggests that the co-administration of RSVpreF and flu vaccines could be a promising option for older adults. It not only offers comprehensive protection against these two significant respiratory infections but also reduces the number of doctor visits. Simplifying this process could increase vaccination rates, which is particularly crucial for this high-risk population.While these results propose co-administration as an effective and safe solution to protect older adults, future studies will need to evaluate the durability of these immune responses and confirm the impact of this approach on reducing severe respiratory illnesses in this population. Combining the two vaccines could transform the preventive management of respiratory infections in seniors, thereby improving their overall health.
Sepsis is a severe condition caused by an
uncontrolled immune response in the body, leading to extensive tissue and organ
damage. Patients with sepsis often experience widespread inflammation,
multi-organ dysfunction, and, in severe cases, septic shock. Without prompt
diagnosis and treatment, this condition can be fatal. Due to its high global
morbidity and mortality rates, early diagnosis and appropriate management are
crucial to improving clinical outcomes.
A promising biomarker in the assessment of sepsis is the Systemic Immune-Inflammation Index (SII). It combines several biological parameters to reflect the balance between immune response and inflammation in the body. Calculated using platelet, neutrophil, and lymphocyte levels, it helps predict disease severity and estimate the prognosis of septic patients, particularly regarding short-term mortality.
This meta-analysis explores the relationship between elevated SII and short-term mortality in sepsis patients. The objective is to determine whether SII can serve as an indicator to identify high-risk patients more quickly and predict the risk of death within days and weeks after hospital admission. This biomarker could enable more targeted management and earlier interventions.
The results show that a high SII is associated with an increased risk of short-term mortality in sepsis patients. The likelihood of death was higher among patients with a high SII (51%) compared to those with a low SII. Subgroup analysis revealed that this association was more pronounced in patients under 67 years of age (RR: 1.72) compared to those over 67 (RR: 1.39). Inflammation in younger patients may have a more severe impact on clinical outcomes.
Future studies should investigate the role of SII in the long-term monitoring of sepsis patients to better understand its capacity to predict complications after the acute phase. It would also be important to evaluate the impact of treatments targeting the components of SII, such as platelets, neutrophils, and lymphocytes, to determine if their modulation can improve long-term outcomes for these patients. This could contribute to better sepsis management and reduce mortality as well as long-term sequelae.

SII as an Indicator of Mortality in Sepsis Patients?
This study is based on the analysis of 9 patient cohorts with sepsis, totaling 25,626 participants. The cohorts include patients of various age groups, sexes, and comorbidities to ensure representativeness and minimize selection bias. SII was measured upon hospital admission, while mortality was tracked over a 90-day period following admission.The results show that a high SII is associated with an increased risk of short-term mortality in sepsis patients. The likelihood of death was higher among patients with a high SII (51%) compared to those with a low SII. Subgroup analysis revealed that this association was more pronounced in patients under 67 years of age (RR: 1.72) compared to those over 67 (RR: 1.39). Inflammation in younger patients may have a more severe impact on clinical outcomes.
SII: A Reliable Tool for Predicting Short-Term Mortality
The analyses demonstrate that SII is a reliable and accessible indicator for predicting short-term mortality in sepsis patients, regardless of sex, follow-up duration, or measurement method. Thanks to its simplicity and the ease of measuring its components in standard laboratory tests, this biomarker could improve risk stratification in clinical settings, enabling more targeted management and earlier interventions.Future studies should investigate the role of SII in the long-term monitoring of sepsis patients to better understand its capacity to predict complications after the acute phase. It would also be important to evaluate the impact of treatments targeting the components of SII, such as platelets, neutrophils, and lymphocytes, to determine if their modulation can improve long-term outcomes for these patients. This could contribute to better sepsis management and reduce mortality as well as long-term sequelae.
Deep surgical site infections (DSSIs) following orthopedic interventions
are a common complication that can delay healing and hinder patient recovery.
These infections affect deep tissues and may result in persistent pain,
prolonged hospital stays, and additional interventions. They also increase
medical costs due to extended treatments and intensive care. In the long term,
DSSIs can impair mobility and reduce patients’ quality of life.
This study investigates the risk factors associated with the occurrence of DSSIs after orthopedic trauma surgeries. The aim is to better understand variables such as underlying medical conditions, surgical practices, and injury characteristics that may contribute to the development of these severe infections.
This study investigates the risk factors associated with the occurrence of DSSIs after orthopedic trauma surgeries. The aim is to better understand variables such as underlying medical conditions, surgical practices, and injury characteristics that may contribute to the development of these severe infections.
What Are the Main Risk Factors for DSSIs?
Researchers analyzed data from 22,318 patients, of whom 894 developed DSSIs, to identify the factors predisposing patients to these severe infections. The primary risk factors identified include:- Male sex (OR = 1.99)
- Active smoking (OR = 2.60)
- Open injuries (OR = 3.17)
- Body Mass Index (BMI) over 26.0 kg/m² (OR = 1.95)
- Wound class ≥2 (OR = 2.40)
- Surgery duration exceeding 60 minutes (OR = 2.41)
Toward Better Infection Management
This study demonstrates that various factors, including underlying medical conditions, surgical practices, and injury characteristics, play a critical role in the development of DSSIs. The findings encourage measures such as weight loss and smoking cessation before surgery to optimize surgical procedures and improve wound management.
Alcohol consumption can have serious health consequences, particularly
when combined with metabolic disorders. Alcohol plays a significant role in the
development of liver diseases such as hepatic steatosis and steatohepatitis,
which can progress to cirrhosis or liver cancer if left untreated. When
combined with conditions like obesity, type 2 diabetes, and hypertension, the
risk of severe liver disease increases significantly.
This study explores how alcohol, in conjunction with these metabolic dysfunctions, contributes to the development of specific alcohol-related liver diseases, termed MetALD (Metabolic Dysfunction-Associated Alcohol-Related Liver Disease).
The findings reveal that alcohol consumption is closely linked to cardiometabolic conditions such as hypertension, hypertriglyceridemia, and hyperglycemia. Alcohol exacerbates these risks, worsening metabolic dysfunction and liver health. Additionally, the study highlights that diagnosing MetALD requires precise identification of alcohol consumption patterns and metabolic risk factors. However, this diagnosis can be challenging due to variability in drinking behaviors.
This study explores how alcohol, in conjunction with these metabolic dysfunctions, contributes to the development of specific alcohol-related liver diseases, termed MetALD (Metabolic Dysfunction-Associated Alcohol-Related Liver Disease).
The Combined Risks: Alcohol and Metabolic Dysfunctions
To identify the combined risks and differentiate liver diseases caused solely by alcohol (ALD) from those influenced by both alcohol and metabolic disorders (MetALD), the study evaluated patients’ alcohol consumption habits using biomarkers such as PEth and validated questionnaires. Input from relatives or healthcare professionals was also included. Metabolic factors like hypertension, diabetes, and hypertriglyceridemia were assessed, along with their interaction with alcohol.The findings reveal that alcohol consumption is closely linked to cardiometabolic conditions such as hypertension, hypertriglyceridemia, and hyperglycemia. Alcohol exacerbates these risks, worsening metabolic dysfunction and liver health. Additionally, the study highlights that diagnosing MetALD requires precise identification of alcohol consumption patterns and metabolic risk factors. However, this diagnosis can be challenging due to variability in drinking behaviors.
Toward More Accurate Diagnosis and Better Management
The study emphasizes the importance of comprehensive alcohol consumption assessment using biomarkers like PEth and validated questionnaires to enhance diagnostic accuracy, particularly in patients with multiple risk factors. Continuous monitoring and strategies to reduce alcohol consumption could slow the progression of liver diseases. By clearly distinguishing MetALD from ALD, treatments and patient management can be optimized to address combined risk factors effectively.
