Physical Activity as a Predictor of Internet Gaming Disorder in a Swiss Male Cohort (C-SURF): L’activité physique comme prédicteur des troubles liés aux jeux vidéo en ligne dans une cohorte de jeunes hommes suisses (C-SURF)

History and Objectives This study addresses the increasing global concerns surrounding Internet gaming disorder (IGD) by exploring their connection to physical activity (PA) as a potential preventive and early intervention measure. The research aims to examine the relationship between PA and the progression of IGD. Methods Longitudinal data from the Cohort research on Substance Use Risk Factors involving young Swiss men undergoing army conscription was employed. PA levels were assessed using the International PA Questionnaire (IPAQ), while the Game Addiction Scale (GAS) and Compulsive Internet Use Scale determined IGD presence. Analysis involved zero-inflated negative binomial regression models. Results Higher PA levels were associated with lower IGD risk. Notably, individuals engaging in high physical exercise exhibited a lower IGD prevalence compared to those with moderate or low activity levels. Discussion The study suggests that intensive physical exercise might serve as a preventive strategy against developing IGD. This protective effect could stem from various mechanisms. However, the study's limitations, such as a male-only sample and a small low-activity group, should be considered when interpreting results. Conclusion The longitudinal study demonstrates the positive influence of intense physical exercise on mitigating gaming-related issues. These findings underscore the potential of PA interventions in addressing the growing problem of IGDs and their impact on health. Further research is necessary to uncover underlying mechanisms behind the PA–IGD relationship and validate these findings across diverse demographics.

Application of superb microvascular imaging technology in clinical disease activity of rheumatoid arthritis.

Detection of synovitis is essential for assessing the activity and predicting the prognosis of rheumatoid arthritis (RA). The aim of this study was to investigate the diagnostic performance of superb microvascular imaging (SMI) in RA patients with high, moderate, and low activity. One hundred four patients with active RA were selected from the hospital between May 2022 and August 2023. The study observed the correlation between bone erosion of the carpal joint, joint cavity effusion, thickness of synovial hyperplasia of the carpal joint, positivity rate of synovial blood vessels, and their semiquantitative scores with the clinical disease activity of RA using SMI examination. The detection of synovial hyperplasia thickness and joint effusion in the high-activity group was higher than that in the low-activity group, and the difference was statistically significant (P < 0.05). The quantitative SMI test demonstrated that the synovial blood flow grading and semiquantitative grade increased gradually with activity level (P<0.05). During the high, moderate, and low-activity groups, the vascular index (VI) value of the hyperplastic synovial membrane decreased gradually, showing statistical significance both between and within the groups (P<0.05). SMI technology exhibited high sensitivity and accuracy in assessing disease activity in RA. It holds significant clinical application value as a reliable auxiliary tool for assessing disease activity in RA and treatment. Key Points • Super micro-vascular imaging (SMI) demonstrated higher detection rates of microvesselsin RA patients with high disease activity compared to those with low activity, showing statistical significance. • The quantitative SMI test revealed a clear correlation between synovial blood flow grading and disease activity levels in RA patients, highlighting the potential of SMI as a valuable tool for disease activity and treatment of rheumatoid arthritis.

A green strategy to realize the high value utilization of lignin for hydrogel formation

Grafting lignin extracted from pulping black liquor onto hydrogel not only endows hydrogel with strong adsorption capacity, but also realizes the high value utilization of lignin, thereby alleviating the environmental pressure caused by the exhaust gas generated by direct combustion of black liquor. However, those lignin fragments have lost generous active functional groups as the high temperature polycondensation during industrial production, restricting the improvement of lignin-based hydrogel adsorption capacity. Herein, we propose a strategy combining amination and oxidation to prepare lignin derivatives with low molecular weight and high activity groups. The introduced amino groups promote the Cα-Cβ cleavage of β-O-4 unit and the oxidation treatment converts S-unit hydroxyl to carboxyl. The hydrogel obtained by grafting aminated-oxidized-lignin shows satisfactory adsorption performance with a methylene blue adsorption capacity of 697.47 mg/g (vs. 195.12 mg/g for pristine hydrogel). The retention ability has also been greatly improved that only 0.43 % of the adsorbed methylene blue is released even after 96 h (vs. 5 % within just 12 h for pristine hydrogel). This work not only provides a new strategy for the high-value utilization of biomass resources, but also offers a new idea for the preparation of hydrogels with high adsorption performance.

Association of macronutrient intake, physical activity, anxiety, and depression with sleep quality among Iranian male adolescents

BackgroundAdolescence is a unique stage of life accompanied by physiological and psychological modifications, along with stress, confusion, and depression.Materials and methodsThe present descriptive-analytical cross-sectional research was done on 267 male adolescents who studied at high schools in Zanjan, Iran. Demographic characteristics questionnaires, a 48-item food frequency questionnaire, a short version of the International Physical Activity Questionnaire (IPAQ), the Depression Anxiety Stress Scale (DASS-21), and the Pittsburgh Sleep Quality Index (PSQI) were used to collect data.ResultsThe mean ± standard deviation (SD) of age, weight, height, and sitting time was 15.94 ± 0.91 years, 68.53 ± 15.28 kg, 1.75 ± 0.06 m, and 449.25 ± 322.06 min, respectively. The study results showed that students with poor sleep quality showed a higher rate of depression than those with good sleep quality in the high and low physical activity groups (p < 0.05). The stress, depression, and anxiety scores significantly correlated with sleep quality in the physical activity groups (p < 0.05). The structural equation model analysis results showed that mental health directly affected sleep quality; this association was significant in the low physical activity group.ConclusionWe found that sleep quality was independently related to mental health in young Iranian men. However, dietary intake was not a significant predictor of mental health or sleep quality. More studies are required to evaluate the association between dietary intake and sleep quality in adults.

Viral genetics and transmission dynamics in the second wave of mpox outbreak in Portugal and forecasting public health scenarios

ABSTRACT In 2023, a second wave of the global mpox epidemic, which is mainly affecting men who have sex with men (MSM), was observed in some countries. Herein, we benefited from a large viral sequence sampling (76/121; 63%) and vast epidemiological data to characterise the re-emergence and circulation of the Monkeypox virus (MPXV) in Portugal during 2023. We also modelled transmission and forecasted public health scenarios through a compartmental susceptible-exposed-infectious-recovered (SEIR) model. Our results suggest that the 2023 mpox wave in Portugal resulted from limited introduction(s) of MPXV belonging to C.1.1 sublineage, hypothetically from Asia, followed by sustained viral transmission and potential exportation to other countries. We estimated that the contribution of the MSM high sexual activity group to mpox transmission was 120 (95% CrI: 30–3553) times higher than that of the low sexual activity group. However, among the high sexual activity group, vaccinated individuals likely contributed approximately eight times less [0.123 (95% CrI: 0.068–0.208)] than the unvaccinated ones. Vaccination was also linked to potential reduced disease severity, with a Mpox Severity Score of 6.0 in the vaccinated group compared to 7.0 in unvaccinated individuals. Scenario analysis indicated that transmission is highly sensitive to sexual behaviour, projecting that a slight increase in the MSM sub-population with high sexual activity can trigger new mpox waves. This study strongly supports that continued vaccination, targeted awareness among risk groups and routine genomic epidemiology is needed to anticipate and respond to novel MPXV threats (e.g. global dissemination of clade I viruses).

The Link between Salivary Amylase Activity, Overweight, and Glucose Homeostasis.

Butyrate, a short-chain fatty acid (SCFA) produced by the fermentation of dietary fibers in the colon, plays a pivotal role in regulating metabolic health, particularly by enhancing insulin sensitivity. Given the rising incidence of metabolic disorders, understanding the factors that influence butyrate production is of significant interest. This study explores the link between salivary amylase activity and butyrate levels in overweight women of reproductive age. Participants were categorized into low (LSA) and high (HSA) salivary amylase activity groups and further divided into two subgroups: one followed a low-starch diet (LS), and the other underwent caloric restriction (CR). We assessed salivary amylase activity and measured serum butyrate concentrations to examine their associations. Our findings showed a significant, though weak, positive correlation (ρ = 0.0486, p < 0.05), suggesting a link between salivary amylase activity and butyrate levels. The statistical significance, despite the weak correlation, implies that this relationship is not random. Moreover, higher baseline butyrate levels were observed in women with elevated salivary amylase activity. Also, women with low salivary amylase activity on a low-starch diet experienced a more pronounced increase in butyrate levels compared to those on caloric restriction. These results suggest that salivary amylase activity and dietary intake interact to influence butyrate production, with potential implications for improving insulin sensitivity and metabolic health. The study underscores the potential of butyrate in enhancing insulin sensitivity and promoting overall metabolic well-being. Further research is necessary to clarify the mechanisms involved and to understand the long-term effects of butyrate on metabolic health across different populations.

REM sleep without atonia and neurocognitive function in isolated REM sleep behaviour disorder: Cross-sectional and longitudinal study.

This study investigated the relationship between rapid eye movement sleep without atonia and cognitive profiles in individuals diagnosed with isolated rapid eye movement sleep behaviour disorder, assesssing both cross-sectional associations and their link to phenoconversion in a longitudinal follow-up. Participants underwent video-polysomnography, neurological examination, neuropsychological tests and structured interviews to confirm isolated rapid eye movement sleep behaviour disorder. Rapid eye movement sleep without atonia was manually scored using the Montreal method, and participants were categorized into either high or low electromyography activity groups, based on their tonic and phasic electromyography activities. The cross-sectional study included 250 patients with isolated rapid eye movement sleep behaviour disorder, revealing that those with high tonic electromyography activity exhibited significantly lower scores in the constructional praxis recall than those with low tonic electromyography activity (p = 0.002). In the longitudinal study, 79 participants (63 isolated rapid eye movement sleep behaviour disorder and 16 phenoconversion), tracked for at least 5 years, demonstrated that high tonic electromyography activity (odds ratio: 6.14; 95% confidence interval: 1.23-30.60; p = 0.027) and lower performance on the Trail Making Test A (odds ratio: 0.23; 95% confidence interval: 0.11-0.70; p = 0.007) were associated with future phenoconversion. These results confirm the link between tonic electromyography activity and neurodegeneration in isolated rapid eye movement sleep behaviour disorder. Combining rapid eye movement sleep without atonia assessment with cognitive evaluation could serve as an early predictive marker for phenoconversion in clinical settings.

Influence of Pain, Risk Factors, and Functional Ability on Physical Activity Levels in Women with Anterior Knee Pain: A Cross-Sectional Study.

Background and Objectives: Anterior knee pain (AKP) refers to chronic prepatellar pain and is one of the most common knee complaints in physically active women. This condition can significantly affect daily activities and overall quality of life. This study aims to assess the impact of pain, risk factors, and functional ability on different levels of physical activity (comparing low versus moderate activity) in women with AKP. Materials and Methods: This cross-sectional study involved fifty-six women diagnosed with AKP (aged 20-45 years) who were equally allocated into low and moderate physical activity groups. Their AKP and functional ability were assessed using the visual analog scale (VAS) and double squats and step-down tests, respectively. Possible risk factors were assessed using the Q-angle, modified Thomas test, sit and reach test, and patellar glide test. A person's correlation coefficient and independent t-tests were used to determine the relationship and the differences between these variables while keeping the confidence interval level at 95%. Result: Women with moderate activity levels showed significantly higher scores on the VAS than those with low activity levels (p = 0.040). However, both groups had no significant difference in their functional ability or potential risk factors (p > 0.05). Additionally, their functional ability (double squat) showed a positive association with hamstring flexibility (Pearson correlation coefficient [r]:0.3; p = 0.006). Conclusions: Women with AKP who were engaged in moderate physical activity experienced higher levels of pain compared to those with low activity levels. These findings underscore the urgent need for further investigation into different levels of physical activity to develop appropriate prevention and treatment strategies for women with AKP.

Association of Physical Activity Levels with Coronary Artery Disease Risk Factors in Middle aged (40-55) Bangladeshi Women

Background: A sedentary lifestyle is associated with increased risk of Coronary Artery Disease (CAD) in women. At least 150min/wk of moderate activity or 75min/wk of vigorous activity or combination is recommended by American Heart Association (AHA) for primary prevention of CAD. The purpose of this study was to assess the physical activity levels of middle aged women and to find out the association of CAD risk factors with physical activity level. Methods: This cross-sectional analytical study was conducted in Dhaka Medical College Hospital (DMCH) cardiology OPD from May 2019 to April 2020. We interviewed 249 middle aged women (40-55) who attended our OPD during the study period and fulfilled the exclusion and inclusion criteria. Global Physical Activity Questionnaire (GPAQ) was used to assess physical activity level. Blood pressure and BMI was measured. OGTT and fasting lipid profile was done. Subjects with low physical activity was assigned in Group I (n=152), moderate activity in group II (n= 93) and high activity in group III (n= 4). Association between the physical activity levels and presence of CAD risk factors like DM, HTN, dyslipidemia and obesity was evaluated. Results: In this study we found that most of the study subjects (61.0%) were in low active group. Overall 70.2% women were menopausal and premature menopause (≤50 years) was found in 47.8% of subjects. Mean age of menopause was 47±3.8; (44-53) years and mean duration of menopause was 3.1±0.5 years. Overall prevalence of DM, HTN, obesity and dyslipidemia was 62.2%, 50.6%, 39.8% and 53.4% accordingly. Women in low active group were having significant higher proportion of DM (52.6%), HTN (65.8%), obesity (57.9%) and dyslipidemia (75.7%) in comparison to moderate active group. Only 4 women were in highly active group and none of the CAD risk factors was present among them. Bangladesh Heart Journal 2024; 39(2): 127-137

Effect of serum diamine oxidase activity derived from response to chemotherapy on adverse events and serum amino acid concentrations for esophageal cancer.

55 Background: The relationship between activity of the small intestinal villi and the effectiveness of chemotherapy remains unclear. This study aimed to investigate how serum diamine oxidase (DAO) activity affects antitumor effects, adverse events, and amino acid absorption. Methods: We performed a single-center prospective cohort study that enrolled 50 patients with esophageal cancer (EC) receiving docetaxel, cisplatin, and 5-fluorouracil therapy. We determined the cut-off value of serum DAO activity contributing to a response to chemotherapy using a generalized additive model. Additionally, we compared adverse events, inflammatory markers, blood amino acid levels, and quality of life between the high and low DAO activity groups during chemotherapy. Results: The cut-off value of serum DAO activity at the first visit that contributed to a chemotherapy response was 6.5 units/L. Leukopenia and neutropenia of Grade ≥3 were significantly higher in the DAO low (&lt;6.5 units/L) group ( p = 0.044, 0.017, respectively). Interleukin-6 was significantly lower in the DAO high (≥6.5 units/L) group at the first visit and at 4 weeks after the end of chemotherapy ( p = 0.039, 0.011, respectively). Glutamine was higher in the DAO high group at all measurement points during chemotherapy. Fatigue was significantly lower in the DAO high group ( p = 0.001). Conclusions: Serum DAO activity may be a predictor of the response to chemotherapy in patients with EC. The absorption capacity of amino acids was maintained in the group with high DAO activity, which may have contributed to the anti-inflammatory effect and provided a background for reducing adverse events.

Effect of Physical Activity on the Association Between Diet and Constipation: Evidence From the National Health and Nutrition Examination Survey 2007-2010.

Previous studies have shown that diet and physical activity can influence constipation. However, the combined effect of diet and physical activity on constipation remains unclear. Constipation was defined based on stool consistency and frequency, while overall diet quality was assessed using Healthy Eating Index (HEI)-2015 scores. Participants were categorized into low (metabolic equivalent [MET]-min/wk < 500) and high physical activity groups (MET-min/wk ≥ 500). The association between diet and constipation across physical activity groups was analyzed using survey logistic regression and restricted cubic splines. Higher HEI-2015 scores were associated with reduced constipation risk in the high physical activity group when constipation was defined by stool consistency (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97-0.99). However, in the low physical activity group, increased HEI-2015 scores did not significantly affect constipation risk (OR, 1.01; 95% CI, 0.97-1.05). Similar results were found when constipation was defined based on stool frequency. In the high physical activity group, increased HEI-2015 scores were significantly associated with a reduced constipation risk (OR, 0.96; 95% CI, 0.94-0.98). Conversely, in the low physical activity group, increased HEI-2015 scores did not affect the risk of constipation (OR, 0.96; 95% CI, 0.90-1.03). Our findings suggest that a higher HEI-2015 score is negatively associated with constipation among individuals with high physical activity levels but not among those with low physical activity levels. This association was consistent when different definitions of constipation were used. These results highlight the importance of combining healthy diet with regular physical activity to alleviate constipation.

Association between physical, cognitive, and social activities with the incident of sarcopenia among community-dwelling older adults: a 4-year longitudinal study.

The purpose of the present study was to comprehensively examine the association between inadequate physical activity (PA), cognitive activity (CA), and social activity (SA) and the development of sarcopenia. We conducted a two-wave survey. In the first-wave survey, we asked participants five questions for each of the three categories-PA, CA, and SA. The low-activity group was defined as those who fell into the decline category for one or more of the five questions. In both Wave 1 and Wave 2, we assessed the sarcopenia status of our participants. The revised definition of the European Working Group on Sarcopenia in Older People 2 was used to determine sarcopenia, and the Asian Working Group for Sarcopenia criteria were used for cut-off points for muscle mass, grip strength, and walking speed. In the second wave, we were able to follow 2,530 participants (mean age 75.0 ± 4.7years, 47.8% men). A multivariable logistic regression showed that low-PA participants face a higher risk of incident sarcopenia, both before and after multiple imputations (odds ratio [OR] 1.62, 95%confidence interval (CI) 1.22-2.15 before imputation; OR 1.62, 95% CI 1.21-2.18 after imputation); the low-SA group also showed a higher risk of incident sarcopenia both before and after multiple imputations (OR 1.31, 95% CI 1.05-1.64 before imputation; OR1.33, 95% CI 1.07-1.65 after imputation). Each low PA and SA independently led to incident sarcopenia late in life. Encouraging not only PA, but also SA, may be effective to prevent sarcopenia among older adults.

The multi-modal sensory effect on sour taste perception during oral processing of starch-thickened fluids

Sour taste is one of the fundamental taste attributes and considered as a saliva secretion stimulant facilitating consumers with xerostomia and swallowing difficulties. The dynamic sour taste perception during oral processing of starch-thickened fluid was therefore investigated in this study. Recruited healthy subjects were divided into those with high (H_AMS) and low (L_AMS) salivary α-amylase activity groups and their temporal dominant sensory evaluation were analyzed while oral processing starch-thickened fluid samples with different concentration of citric acid. By simultaneously evaluating the physical and chemical properties of subjects' expectorated fluid/saliva mixtures, the complex and multi-modal interplay between fluid viscosity (tactile perception), citric acid concentration (taste perception), salivary α-amylase activity (binary taste interaction) was successfully demonstrated. The sour taste perception was found to be greatly affected by the continuous starch-thickened fluid hydrolysis by salivary α-amylase, resulting in a gradual production of sweet-tasting oligosaccharides and simultaneous decrease in fluid viscosity, and group variations (H_AMS vs. L_AMS) were pronouncedly observed in the hydrolyzed oligosaccharide concentrations (glucose, maltose, and maltotriose) which suitably corresponded to the selected dominant sensory attributes including perceived taste differences and taste dominant duration. These findings suggest that salivary biochemical properties and the thickened fluid type greatly influence consumers’ sensory perception. This could provide valuable insights for designing and optimizing thickened foods and beverages that are palatable in sensory properties and meet the needs of special consumers.

The impact of physical activity on patient-reported outcomes following deep inferior epigastric perforator flap breast reconstruction

IntroductionWhile higher pre-operative physical activity levels have been shown to be beneficial to post-operative recovery at large, their effect on patient reported outcomes after DIEP flap breast reconstruction has yet to be investigated. This study aims to correlate patient physical activity levels with patient-reported outcome measures. MethodsA prospectively maintained database of patients who underwent DIEP flap breast reconstruction between July 2021 and June 2022 was analysed. Physical activity levels were assessed using the Global Physical Activity Questionnaire (GPAQ) and patient-reported outcomes were measured using the BREAST-Q questionnaire, both pre-operatively and one year post-operatively. Patients were stratified into low (<1000 METs) and high (>1000 METs) physical activity groups. ResultsOf the 136 patients who underwent surgery, 51 completed both questionnaires, with 34 responses meeting completeness criteria for statistical analysis. The low-MET group (n=19) and high-MET group (n=15) were comparable in age and co-morbidities. Post-operatively, the low-MET group exhibited a 54% increase in physical activity levels, while the high-MET group showed a 17% decrease (p<0.01). The low-MET group experienced significant declines in psychosocial well-being (9.3%, p=0.04) and sexual well-being (14%, p=0.02), whereas the high-MET group did not show significant changes in these domains. Satisfaction with the unclothed abdomen increased significantly in the low-MET group (2.9 from 2, p=0.001), while the high-MET group showed a non-significant decrease (3.2 from 2.9, p=0.43). However, abdominal well-being significantly decreased in both groups, with a 56% decline in the high-MET group (p=0.006) and a 51% decline in the low-MET group (p=0.0002). The latter reflecting the perceived difference between aesthetic appearance and wellbeing. ConclusionsPatients with lower pre-operative physical activity levels showed improved activity post-surgery, potentially due to motivational factors from the reconstructive process. Conversely, those with higher pre-operative activity levels faced greater challenges in maintaining their activity levels post-surgery, potentially arising from disruptions in daily routines and donor site symptoms, indicating a need for targeted interventions to support this group. Concurrently, patients with higher baseline exercise levels did not show a decrease in psychosocial and sexual wellbeing, possibly reflecting a higher resilience to the operative process. These findings underscore the importance of integrating physical activity assessments into pre-operative evaluations to inform patient-centred care and optimize recovery outcomes.

A risk score based on polyamine metabolism and chemotherapy-related genes predicts prognosis and immune cells infiltration of lung adenocarcinoma.

We aimed to explore whether the genes associated with both platinum-based therapy and polyamine metabolism could predict the prognosis of LUAD. We searched for the differential expression genes (DEGs) associated with platinum-based therapy, then we interacted them with polyamine metabolism-related genes to obtain hub genes. Subsequently, we analysed the main immune cell populations in LUAD using the scRNA-seq data, and evaluated the activity of polyamine metabolism of different cell subpopulations. The DEGs between high and low activity groups were screened to identify key DEGs to establish prognostic risk score model. We further elucidated the landscape of immune cells, mutation and drug sensitivity analysis in different risk groups. Finally, we got 10 hub genes associated with both platinum-based chemotherapy and polyamine metabolism, and found that these hub genes mainly affected signalling transduction pathways. B cells and mast cells with highest polyamine metabolism activity, while NK cells were found with lowest polyamine metabolism activity based on scRNA-seq data. DEGs between high and low polyamine metabolism activity groups were identified, then 6 key genes were screened out to build risk score, which showed a good predictive power. The risk score showed a universal negative correlation with immunotherapy checkpoint genes and the cytotoxic T cells infiltration. The mutation rates of EGFR in low-risk group was significantly higher than that of high-risk group. In conclusion, we developed a risk score based on key genes associated with platinum-based therapy and polyamine metabolism, which provide a new perspective for prognosis prediction of LUAD.

Nonlinear dose-response association of moderate-to-vigorous physical activity with hyperuricemia in US adults: NHANES 2007-2018.

The relationship between physical activity and hyperuricemia (HUA) remains inconsistent, and the dose-response association between moderate-to- vigorous physical activity (MVPA) level and HUA still unclear. In this study, we aimed to investigate the dose-response association of MVPA with HUA, and to explore an appropriate range of MVPA level for preventing HUA. Data from the US National Health and Nutrition Examination Survey (NHANES) 2007-2018 were used, including 28740 non-gout adult Americans. MVPA level was self-reported using the Global Physical Activity Questionnaire and serum uric acid was measured using timed endpoint method. The dose-response relationship between MVPA level and HUA was modeled with restricted cubic spline analysis. Logistic regression analysis were applied to estimate odd ratios (ORs) and 95% confidence intervals (CIs) of the relationships between MVPA level and HUA. A total of 28740 adults were included in the study (weighted mean age, 47.3 years; 46.5% men), with a prevalence rate of HUA was 17.6%. The restricted cubic spline functions depicted a general U-shaped relationship between MVPA level and HUA. The MVPA level of 933 and 3423 metabolic equivalent (MET) -min/wk were the cut-off discriminating for the risk of HUA. Participants with MVPA levels in the range of 933-3423 MET-min/wk had lower risk of HUA and they had the lowest risk when MVPA levels at around 1556 MET-min/wk. Compared with the moderate-activity group (600-2999 Met-min/wk), the low-activity group (< 600 Met-min/wk) had a greater risk of HUA (OR, 1.13 [95%CI, 1.02-1.26]) after fully adjusting for potential confounders. Compared with the moderate MVPA level, the low MVPA level was associated with the higher risk of HUA. And there may be a U-shaped dose-response relationship between MVPA level and HUA. When MVPA level was approximately 933-3423 MET-min/wk, the risk of HUA may at a lower level and the risk reached the lowest when MVPA level at around 1556 MET-min/wk.

Physical activity trajectories and all-cause mortality in type 1 diabetes: A nationwide longitudinal study

AimsTo identify physical activity trajectories, explore the factors associated with them and assess their relationship with all-cause mortality. MethodsThis was a population-based longitudinal cohort study, with data from all specialist care units for type 1 diabetes in Sweden. A total of 48.921 adult patients were included, each with at least 3 registrations of physical activity, and a maximum follow-up of 14 years. The main outcomes were the longitudinal physical activity trajectories and all-cause mortality. ResultsOf 48.921 patients, 55.9% were males and mean (SD) age was 39.7(16.7). Four physical activity trajectories were identified: Steady Low (10.8%), Decreaser (12.7%), Increaser (20.7%) and Steady High (55.8%). Female sex, higher education, higher income, normal BMI, fewer comorbidities and foot free from diabetic disease were significantly associated with sustained high physical activity. Compared to the steady low group, the decreaser, increaser, and steady high physical activity groups exhibited lower adjusted risk of all-cause mortality (53–73% reduction). ConclusionsConsistently low physical activity is associated with higher all-cause mortality. This study underscores the importance of identifying patients at risk of low physical activity and tailoring personalized approaches to promote sustained physical activity in type 1 diabetes, ultimately improving outcomes.

Assessing effective half-life of I-131 in 39 thyroid cancer patients at Dong Nai General Hospital

Radioiodine therapy to kill the residual cells after surgery in thyroid cancer patients is a widespread treatment method nowadays. Despite the therapeutic benefits, the amount of I-131 that remains in the patient's body also causes radiation risks to caregivers and persons in close contact. This study assesses the effective half-life () of I-131 in 39 patients underwent thyroid cancer treatment at Dong Nai General Hospital. Radioactive activity on the patient's body was measured by survey meter GAL20-C (ELSE SOLUTIONS), placed 1.0 meters away from the patient, at 0.5; 2.0; 4.0; 6.0; 24.0 hours; and 7 days after administration. The measurement data was fitted by a mono-exponential function respecting time by the least squares method to figure out the effective half-life. The result function has a good coefficient of determination, R2 ~ 1, Te was 7.89 +- 1.55 h (high-activity group), and 5.83+-1.76 h (low-activity group). The effective half-life was proved to be different between these two groups of patients.

A longitudinal study of the association between physical activity and apathy among community-dwelling older adults

This study clarified the association between the amount of physical activity and apathy after one year among community-dwelling older adults. Two hundred community-dwelling older adults (mean age: 74.3±5.0 years old, female: 52.5%) who participated in the 2018 and 2019 "Kasama Longevity Health Examination" were included. Apathy was assessed using the Apathy Scale (0-42 points; the higher the score, the lower the motivation), physical activity by Physical Activity Scale for the Elderly (PASE), and Geriatric Depression Scale-15 (GDS). The 2018 PASE data were grouped into tertiles. A multiple regression analysis was performed with the 2019 Apathy Scale as the dependent variable and the 2018 PASE as the independent variable, and the sex, age, years of education, economic situation, body mass index, chronic illness, smoking history, alcohol drinking habits, physical function, cognitive function, GDS, and the 2018 Apathy Scale as adjustment variables. The PASE subcategories (leisure-time, household, and work-related activities) were examined using a similar method. The mean Apathy Scale in 2019 was 14.0±6.2 for the low physical activity group, 12.8±6.0 for the medium physical activity group, and 10.1±5.9 for the high physical activity group. The high physical activity group showed a significant negative association with the Apathy Scale (B=-1.56, 95% confidence interval=-2.91 to -0.21, p=0.023). No association was found for any activity of the PASE sub-items. A high level of physical activity may protect against apathy among community-dwelling older adults.
