Moderate to intense physical activity is associated with improved clinical, CD4/CD8 ratio and immune activation status in HIV infected patients on ART

Background Physical activity has anti-inflammatory effects and reduces morbidity and mortality in general population, but its role in the clinical, CD4/CD8 ratio and immune activation status in HIV-infected patients has been poorly studied. Methods A cross-sectional study was carried out in a cohort of 155 HIV-infected patients on stable ART to compare clinical, biochemical, CD4/CD8 ratio and immune-activation status according to their physical activity in the last two years (sedentary/low vs. moderate/intense) assessed by the iPAQ. A binary logistic regression and mixed ANOVA were performed to evaluate the impact of levels of physical activity on CD4/CD8 ratio. Results In our series 77 (49.7%) out of 155 patients were sedentary and 78 (50.3%) practiced moderate/intense physical activity. Moderate/intense physical activity was associated with lower CDC HIV-stage (p=0.046), better metabolic control (lower BMI, p=0.024; glucose, p=0.024; and triglyceride, p=0.002), higher CD3 +CD4 + T lymphocytes (p=0.016), lower CD8 + T lymphocytes (p=0.018), higher CD4/CD8 ratio (p=0.001), lower CD4 +CD8 + (p=0.026), CD4 +CD86 + (p=0.045), CD4 +HLA-DR + (p=0.011), CD8 +HLA-DR + (p=0.048) T lymphocytes and CD16 +HLA-DR + NK cells (p=0.026). Sedentary lifestyle (OR=2.12, p=0.042), CD4 nadir (OR=1.005, p<0.001) and CD8 +CD38 + T cells (OR=1.27, p=0.006) were independently associated with low CD4/CD8 ratio (<0.8). Earlier and more intense CD4/CD8 ratio recovery was observed in patients with higher physical activity in the two-year follow-up with a significant interaction between these variables: F(2, 124) = 3.31, p=0.049, partial η2=0.042). Conclusions Moderate to high physical activity is associated with beneficial health effects, improving metabolic profile and reducing chronic inflammation in patients living with HIV. Although more studies and clinical trials are needed to confirm these findings, healthy lifestyle, including at least moderate physical activity, should be recommended to HIV patients on stable ART.

Impact of physical activity on mental health levels during the Covid-19 pandemic - methods

Intense physical activity leads to high levels of mental health during the Covid-19 pandemic in physically active persons compared to physically passive persons, both for those who are infected with Covid-19, and those who are not.

Brain Changing Advantages of Exercise

Exercise is defined as any activity that causes your muscles to work and your body to burn calories. Physical activity includes swimming, running, jogging, strolling, and dancing, to name a few. Physically and mentally active people have been shown to have various health benefits. It could even help you live a longer life. In this article, we attempt to explain the beneficial effects of exercising regularly on our brain and how this helps with cognitive tasks. We also describe the various neurotrophic neurochemicals that aid in this phenomenon. We then describe the process of neuroplasticity and how exercise can help accelerate this process. Regular physical activity is one of the most important things you can do for your health. If you're worried about being harmed if you start walking or increase your level of physical activity, it is safe for most people to engage in moderate-intensity aerobic activity, such as brisk walking. Reduced emotions of state anxiety (short-term anxiety), increased sleep, and enhanced elements of cognitive performance are some of the benefits of moderate or intense physical exercise on cerebral health that happen immediately after moderate or intense physical activity (acute impact). People who engage in more moderate or intense physical activity generally have better mental processes to gain knowledge and comprehension than those who do not. Improvements in cognition, as well as performance, might be expected. For example, standardized assessments of academic achievement and performance on mental ability tests are examples of neuropsychological testing. Processing speed, memory, and executive function are all factors to consider.

Physical Training Increases Erythroferrone Levels in Men

Intense physical activity contributes to an increased demand for red blood cells, which transport oxygen to working muscles. The purpose of this study was to assess the concentration of erythroferrone (ERFE), the novel marker of erythroid activity in athletes, during the beginning of their training season. The study group consisted of 39 athletes aged 23.24 ± 3.77 years. The study was carried out during the athletes’ preparatory period of the training cycle. The control group consisted of 34 healthy men aged 22.33 ± 2.77 years. The erythropoietic activity was evaluated by determining athletes’ concentrations of erythropoietin (EPO) and erythroferrone (ERFE). The level of physical activity was assessed using the International Physical Activity Questionnaire (IPAQ). In the athletes’ group, we observed higher concentrations of EPO (Me = 12.65 mIU/mL) and ERFE (40.00 pg/mL) compared to the control group (EPO: Me = 5.74 mIU/ml, p = 0.001; ERFE: Me = 25.50 pg/mL, p = 0.0034). The average intensity of physical exercise significantly differentiated the participants as far as EPO and ERFE concentrations. These results suggest that intense physical activity, at least at the beginning of the training season, may stimulate EPO production, which increases ERFE release. This seems to be an adaptative mechanism that provides adequate iron for enhanced erythropoiesis.

Exploring the Efficacy of Comparative Bioarchaeological Approaches in Providing Answers on Marginality and Networking

This paper investigates the efficacy of comparative bioarchaeological approaches in exploring the impact of economic marginality on human lifeways. Skeletal remains from the Late Bronze Age cemetery of Achlada in Northern Greece were chosen to address this, as this specific community was probably less well networked, evident in its location away from major communication routes and the paucity of grave goods at the site. A biocultural methodology combining comparative data on funerary practices and lifestyle was implemented. Sex differences were found within the community and seem to agree with the differential burial placement of the sexes possibly representing the different roles that society symbolically attributed to men and women in deathways. Comparative intercemetery data did not reveal poorer health and diet, or more intense physical activity, compared to well-networked sites. Nonetheless, Achlada, as well as numerous, mostly north communities of the wider context, probably faced more physiological challenges during growth, at least of a mild to moderate level, compared to a number of populations connected by major communication routes. The current study highlights the importance of implementing comparative bioarchaeological approaches as a means of identifying the impact of marginality on human lifeways, particularly in settings with limited material culture information.Limitations linked to preservation issues and the multifactorial nature of lifestyle indicators could be dealt with by future biomolecular and isotopic analyses. Η παρούσα εργασία έχει στόχο να διερευνήσει το κατά πόσο οι συγκριτικές βιοαρχαιολογικές προσεγγίσεις είναι εφικτό να δώσουν απαντήσεις ως προς την επίδραση της οικονομικής περιθωριοποίησης στον ανθρώπινο τρόπο διαβίωσης. Επιλέχθηκαν σκελετικά κατάλοιπα της Ύστερης Εποχής Χαλκού από το νεκροταφείο της Αχλάδας στη Βόρεια Ελλάδα ώστε να απαντηθεί το εν λόγω ερώτημα, καθώς η συγκεκριμένη κοινωνία -βάσει της θέσης της μακριά από τα μεγάλα δίκτυα επικοινωνίας και της παρουσίας πολύ λίγων ταφικών ευρημάτων-ήταν πιθανώς λιγότερο καλά δικτυωμένη. Ακολουθήθηκε μια συνδυαστική βιοπολιτισμική προσέγγιση συγκριτικών ταφικών δεδομένων και συγκριτικών αποτελεσμάτων δεικτών τρόπου διαβίωσης. Βρέθηκαν διαφορές μεταξύ των δύο φύλων στον εν λόγω πληθυσμό οι οποίες φαίνεται να συμφωνούν με την διαφορετική πλευρά κατάκλισής τους, η οποία πιθανώς να συμβόλιζε τη διαφορετικότητα των ρόλων που η κοινωνία απέδιδε σε άντρες και γυναίκες στο ταφικό περιβάλλον. Συγκριτικά αποτελέσματα μεταξύ νεκροταφείων δεν φανέρωσαν χαμηλότερο επίπεδο υγείας και διατροφής, ούτε πιο έντονη εργασιακή καταπόνηση, σε σχέση με καλά δικτυωμένες θέσεις. Παρόλα αυτά, η Αχλάδα, όπως και μια σειρά –κυρίως βόρειων- κοινωνιών τουευρύτερου πλαισίου, πιθανότητα αντιμετώπισαν περισσότερα φαινόμενα καταπόνησης (στρες) κατά τη διάρκεια της ανάπτυξης, τουλάχιστον ήπιου και μετρίου επιπέδου, συγκριτικά με καλύτερα δικτυωμένους πληθυσμούς. Η παρούσα εργασία τονίζει τη σημασία της εφαρμογής συγκριτικών βιοαρχαιολογικών προσεγγίσεων ως μέσο μελέτης της επίδρασης της περιθωριοποίησης στους ανθρώπινους πληθυσμούς, ιδιαιτέρως σε θέσεις με περιορισμένες πληροφορίες υλικού πολιτισμού. Μεθοδολογικοί περιορισμοί οι οποίοι συνδέονται με ζητήματα διατήρησης αλλά και με τον πολυπαραγοντικό χαρακτήρα των δεικτών τρόπου διαβίωσης, ενδεχομένως να αντιμετωπιστούν μέσω των επερχόμενων βιομοριακών και ισοτοπικών αναλύσεων.

Muscular Adverse Events Associated with Statins

Statins are an important group of lipid lowering medications that have helped to control cardiovascular mortality globally. Muscular side effects, mostly myalgia, is a known adverse event of statins. Intense physical activity, kidney or liver failure, hypothyroidism, inherited or metabolic myopathies, and some medications, are risk factors for statin-induced myalgia. Muscular adverse events are more often observed with higher doses or with the use of lipophilic statins. Much is not known about the precise mechanisms responsible for the statin related muscular adverse effects, a few hypothesis have been suggested. It is important to measure plasma creatine phosphokinase in subjects who encounter myalgia while being treated with statins. In this review we present some general safety information on muscular adverse events caused due to statins.

The data were analyzed using descriptive statistics and linear regression with SPSS.Results: When age and body mass index were controlled for, intermediate intense physical activity increased the rate of childbirth, but low or heavy intensity did not.Conclusion: Women who have been diagnosed with infertility should be given advice to engage in intermediate levels of physical activity in order to increase their chances of having a child.

Pseudomonas-Contaminated Pool Triggering an Episode of Idiopathic Palmoplantar Hidradenitis

Idiopathic palmoplantar hidradenitis (IPPH) is a disorder that mainly affects the palms and soles of children. Although many cases have been reported to occur after recreational swimming activities, whether IPPH is caused by intense physical activity or by Pseudomonas infection has yet to be proven. We report a case of a 3-year-old girl who presented with IPPH after swimming in a pool with evidence of <i>P. aeruginosa</i> contamination, further solidifying the association between Pseudomonas and IPPH.

Association of Food Intake Quality with Vitamin D in SARS-CoV-2 Positive Patients from Mexico: A Cross-Sectional Study

One of the micronutrients that has attracted the most attention in relation to COVID-19 is vitamin D. Although several factors affect its sufficiency; it has been argued that an optimal diet can ensure the intake of micronutrients with effects on immune response. Therefore, in this work we aimed to evaluate the food intake quality of SARS-CoV-2 positive Mexican patients and some of the common factors related to vitamin D deficiency. We conducted a cross-sectional study in 40 SARS-CoV-2 positive patients. Serum samples and clinical parameters were collected. Micronutrient intake and food intake quality were assessed with a 24-h dietary recall and the Mini-ECCA v.2, respectively. Thirty-eight percent of the sample had a healthy food intake. The median 25(OH)D concentration was 22.7 ng/mL. A considerable insufficient intake of micronutrients with immunomodulatory effects such as vitamin D (p < 0.0001), vitamin E (p < 0.0001), and zinc (p < 0.0001) was shown. Patients with 25(OH)D sufficiency, defined as a concentration >30 ng/mL, had better food intake quality (p = 0.02) and an intense physical activity (p = 0.03). In conclusion, a better level of food intake quality and intense physical activity are associated with 25(OH)D sufficiency in SARS-CoV-2 positive Mexican patients.

Mobility in Ancient Egypt from the shape and strength of the femurs

The aim of the study was to establish the degree of robustness and to infer the level of mobility of a group from ancient Thebes (Middle Egypt). Seventy-one left femurs of adult individuals from the 1st century AD from the tomb of Monthemhat (Luxor) were studied. Metrical, non-metrical variables, shape and size indices of femur were considered. Stature, body mass and Body Mass Index were calculated. All variables showed higher values in males, the vertical diameter of the femoral head was the variable with the highest sexual dimorphism. Non-metric variables also indicated low robustness, with heterogeneous sex distribution. The robustness, pilastric and platymeric indices indicated that the values were close to those of gracile populations in both sexes. Subtrochanteric size and shape showed no sexual dimorphism. The robustness, size and shape in the middle of the diaphysis suggested a mobility related to a daily occupation without intense physical activity in the legs. The results indicate a profile of low robustness, relative sedentarism with apparent sexual division in daily activities.
