RESUMO
Objectives: For early gastrointestinal lesions, size is an important factor in the selection of treatment. Virtual scale endoscope (VSE) is a newly developed endoscope that can measure size more accurately than visual measurement. This study aimed to investigate whether VSE measurement is accurate for early gastrointestinal lesions of various sizes and morphologies. Methods: This study prospectively enrolled patients with early gastrointestinal lesions ≤20 mm in size visually. Lesion sizes were measured in the gastrointestinal tract visually, on endoscopic resection specimens with VSE, and finally on endoscopic resection specimens using a ruler. The primary endpoint was the normalized difference (ND) of VSE measurement. The secondary endpoints were the ND of visual measurement and the variation between NDs of VSE and visual measurements. ND was calculated as (100 × [measured size - true size] / true size) (%). True size was defined as size measured using a ruler. Results: This study included 60 lesions from April 2022 to December 2022, with 20 each in the esophagus, stomach, and colon. The lesion size was 14.0 ± 6.3 mm (mean ± standard deviation). Morphologies were protruded, slightly elevated, and flat or slightly depressed type in 8, 24, and 28 lesions, respectively. The primary endpoint was 0.3 ± 8.8%. In the secondary endpoints, the ND of visual measurement was -1.7 ± 29.3%, and the variability was significantly smaller in the ND of VSE measurement than in that of visual measurement (p < 0.001, F-test). Conclusions: VSE measurement is accurate for early gastrointestinal lesions of various sizes and morphologies.
RESUMO
PURPOSE: To ensure comparable PET/CT image quality between or within centres, clinical inter-system performance comparisons following European Association of Nuclear Medicine Research Ltd. (EARL) guidelines is required. In this work the performance of the long axial field-of-view Biograph Vision Quadra is compared to its predecessor, the short axial field-of-view Biograph Vision. PROCEDURES: To this aim, patients with suspected tumour lesions received a single weight-based (3 MBq/kg) 2-deoxy-2-[18F]fluoro-D-glucose injection and underwent routine clinical ( â¼ 15 min) scans on the Vision and 3-min scans on the Quadra in listmode in balanced order. Image quality (IQ), image noise (IN), and tumour demarcation (TD) were assessed visually by four nuclear medicine physicians using a 5-point Likert scale and semiquantitative analysis was performed using standardised uptake values (SUVs). Inter-reader agreement was tested using Wilcoxon's signed rank test and the SUVs were statistically compared using a paired t-test. RESULTS: Twenty patients (mean age, 60 years ± 8.8 [standard deviation], 16 male) were enrolled. Inter-reader agreement ranged from good to very good for IQ and IN (0.62 ≤ W ≤ 0.81), and fair for TD (0.29 ≤ W ≤ 0.39). Furthermore, a significant difference was found for TD (p = 0.015) between the systems, showing improved TD for the Quadra. CONCLUSION: This study demonstrates that the Quadra can be used in routine clinical practice with multiple PET/CT systems or in multicentre studies. This system provides comparable diagnostic image quality and semiquantitative accuracy, improved TD, and has the advantage of shorter scan durations.
RESUMO
Background and aims: We aimed to study the association of very low serum Lipoprotein(a) [Lp(a)] concentrations with new-onset type 2 diabetes (T2D) and non-alcoholic liver disease (NAFLD) in the context of statin usage in the UK Biobank, a large prospective population cohort. Methods: Using an extended biomarker dataset, we identified 47,362 participants with very low Lp(a) concentrations (<3.8 nmol/L) from a total of 451,479 participants. With a median follow-up of 12.3 years, we assessed the risk of new-onset cardiometabolic diseases in participants stratified by statin usage with Cox proportional hazards models. We performed two-sample Mendelian randomization MR analyses to test causal relationship between genetically predicted Lp(a) and T2D and NAFLD. Results: Taking the participants with Lp(a) within reportable range as the reference group, the hazard ratios (HR) for T2D were 1.07 (95 % confidence interval, CI 1.01-1.13) and for NAFLD 1.30 (95 % CI 1.20-1.41) respectively for participants with very low Lp(a) (<3.8 nmol/L). The risk for new-onset T2D was higher in participants using statins (adjusted HR 1.15; 95 % CI 1.05-1.27). The risk estimates for new-onset NAFLD were comparable in the analysis stratified by statin use. There was no evidence for causal links between genetically predicted Lp(a) and T2D nor NAFLD in two-sample MR analyses. Conclusions: Very low Lp(a) was associated with higher risks of T2D and NAFLD in a prospective analysis of the UK Biobank. The association with T2D was influenced by lipid lowering medication usage. MR analyses did not support causality for these inverse associations.
RESUMO
PURPOSE: The management of pain following cancer-related surgeries involves the use of opioid analgesics. Nevertheless, there is little evidence characterizing the utility and prescription patterns of opioids after these procedures. Our primary aim was to identify patients from three types of cancer surgery who were overprescribed with opioids. The secondary aim was to determine the potential predictors of overprescribing in the same period. METHODS: We conducted the study at a single cancer referral hospital. Opioid-naïve patients with breast, gynecologic, or head and neck cancer were studied. Patients were considered opioid-naïve if they had a history of opioid use ≤ 30 mg oral morphine equivalent daily dose for less than seven days in the preceding three months before surgery. We recruited eligible participants by convenience sampling on the wards until at least 102 patients were included in the final analysis. After discharge, we followed up on the participants on day 7 via telephone using a structured proforma including questions to identify the last date and amount of opioid dose taken. The equivalent days of opioid use were calculated by their 24-hr use before discharge and the number of doses prescribed for discharge. Our primary outcome was the prevalence of overprescribing in the three surgical specialties defined as the number of patients taking less than 50% of discharge opioids within the first seven days after discharge. We examined the predictors on incidents of overprescribing using multivariable Poisson regression as the secondary outcome. RESULTS: We recruited 119 patients, and 107 patients were included in the final analysis. There were 59/107 (55%) patients found to be overprescribed with opioids. At discharge, they exhibited lower mean numerical rating scale pain scores, lower mean pain severity scores, higher equivalent days of opioids prescribed, and not used opioids in the last 24 hr before discharge. The incidence of overprescribing was 2.4 times greater for patients prescribed with opioids without 24-hr opioid use (relative risk [RR], 2.38; 95% confidence interval [CI], 1.30 to 4.35; P = 0.005). Similarly, the incidence of overprescribing was 1.7 times greater for patients who had opioids 24 hr before discharge and were supplied with opioids for five equivalent days or more at the time of discharge (RR, 1.67; 95% CI, 1.09 to 2.56; P = 0.02). CONCLUSION: Our study shows that the majority of recruited patients undergoing breast, gynecologic, or head and neck cancer surgery were overprescribed opioids. Individualized assessments on patients' 24-hr opioid requirements before discharge and supplying for less than five days are important considerations to reduce overprescribing in opioid-naïve patients after cancer surgery.
RéSUMé: OBJECTIF: La prise en charge de la douleur à la suite d'interventions chirurgicales liées au cancer passe par l'utilisation d'analgésiques opioïdes. Néanmoins, il existe peu de données probantes caractérisant l'utilité et les habitudes de prescription des opioïdes après ces interventions. Notre objectif principal était d'identifier les patient·es de trois types de chirurgie du cancer auxquel·les des opioïdes avaient été surprescrits. L'objectif secondaire était de déterminer les prédicteurs potentiels de surprescription au cours de la même période. MéTHODE: Nous avons mené cette étude dans un seul hôpital de référence pour le cancer. La patientèle naïve aux opioïdes atteinte de cancer du sein, gynécologique ou de la tête et du cou a été étudiée. Les patient·es étaient considéré·es comme naïfs ou naïves aux opioïdes si leurs antécédents d'utilisation d'opioïdes étaient inférieurs ou égaux à une dose quotidienne équivalente à 30 mg de morphine orale pendant moins de sept jours au cours des trois mois précédant la chirurgie. Nous avons recruté les participant·es éligibles par échantillonnage de commodité dans les services jusqu'à ce qu'au moins 102 personnes soient incluses dans l'analyse finale. Après le congé, nous avons fait un suivi téléphonique auprès des participant·es le 7e jour à l'aide d'un formulaire structuré comprenant des questions visant à identifier la dernière date et la dose d'opioïdes prise. Les jours équivalents de consommation d'opioïdes ont été calculés en fonction de leur utilisation dans les 24 heures précédant le congé et du nombre de doses prescrites pour le congé. Notre critère d'évaluation principal était la prévalence de la surprescription dans les trois spécialités chirurgicales, définie comme le nombre de patient·es prenant moins de 50 % des opioïdes reçus au congé dans les sept premiers jours suivant le congé. Nous avons examiné les prédicteurs d'incidents de surprescription en utilisant la régression de Poisson multivariée comme critère d'évaluation secondaire. RéSULTATS: Nous avons recruté 119 patient·es, et 107 patient·es ont été inclus·es dans l'analyse finale. Une surprescription d'opioïdes a été observée pour 59 patient·es sur 107 (55 %). À leur congé, ces personnes présentaient des scores de douleur moyens plus faibles sur l'échelle d'évaluation numérique, des scores moyens de gravité de la douleur plus faibles, des jours équivalents d'opioïdes prescrits plus élevés et n'avaient pas utilisé d'opioïdes dans les 24 heures précédant le congé. L'incidence de surprescription était 2,4 fois plus élevée chez les patient·es à qui l'on avait prescrit des opioïdes sans utilisation d'opioïdes dans les 24 heures (risque relatif [RR], 2,38; intervalle de confiance [IC] à 95 %, 1,30 à 4,35; P = 0,005). De même, l'incidence de surprescription était 1,7 fois plus élevée chez les patient·es qui avaient reçu des opioïdes 24 heures avant le congé et qui avaient reçu des opioïdes pendant cinq jours équivalents ou plus au moment du congé (RR, 1,67; IC 95 %, 1,09 à 2,56; P = 0,02). CONCLUSION: Notre étude montre qu'il y a eu surprescription d'opioïdes pour la majorité des patient·es recruté·es bénéficiant d'une chirurgie de cancer du sein, gynécologique ou de la tête et du cou. Des évaluations individualisées des besoins en opioïdes des patient·es dans les 24 heures avant leur congé et une administration pendant moins de cinq jours sont des considérations importantes pour réduire la surprescription chez les personnes naïves aux opioïdes après une chirurgie oncologique.
RESUMO
BACKGROUND: This is the first study in which the impact of platelet transfusions on seven platelet indices was evaluated in platelet transfusion-dependent patients admitted in the ICU. STUDY DESIGN AND METHODS: Among a cohort of 21 ICU patients prospectively studied over eleven months, a total of 19 ICU patients were enrolled. Seven platelet indices were measured before and then, within 18-24 h, after platelet transfusions using the Sysmex XN-10 analyser and statistically investigated as follows: i) apheresis vs. pooled platelet transfusions; ii) pre- vs. post-platelet transfusions; and iii) platelet count (PC) increment vs. PC decrement group. RESULTS: A 79.2% of platelet transfusion episodes in ICU patients showed an increase in PC increment within 18-24 h, of which 73.7% had a peak percentage immature platelet fraction (%-IPF) above 10.0% during their stay. No difference was observed in the measurements of platelet indices between the apheresis and pooled platelet transfusion doses (all p > 0.05). Of the seven platelet indices investigated, plateletcrit (PCT) and absolute immature platelet count (A-IPF) were not influenced by platelet transfusions and thus proven to be stable (0.06 vs. 0.07%, p = 0.0901 and 4.6 vs. 4.9 × 109/L, p = 0.4559, respectively), despite their close proximity to platelet transfusion. But the overall effectiveness of these indices in detecting changes over time was not hindered. CONCLUSION: A-IPF and PCT are stable after platelet transfusions, regardless of whether patient's respond to or do not respond to platelet transfusion doses. PCT and A-IPF may thus prove useful in monitoring patient transfusion support and guiding management in thrombocytopenic patients.
RESUMO
OBJECTIVE: While previous literature has investigated the psychosocial impact and aesthetic satisfaction associated with post-operative scarring for certain pediatric craniofacial conditions, the impact of the scar burden resulting from craniosynostosis surgery has not been adequately studied. PARTICIPANTS: SCAR-Q was shared with patients ages 8 and older. Thirty-two complete patient responses were recorded. INTERVENTIONS: SCAR-Q is a PROM that consists of three independent scales - appearance, symptoms, and psychosocial impact - associated with a scar. MAIN OUTCOME MEASURES: Mann-Whitney U, linear regression, and Pearson correlation tests were used to evaluate associations between the scales, in addition to patient characteristics such as sex and suture involvement. RESULTS: Mean ages at time of surgery and survey completion were 9.65 ± 10.10 months and 12.10 ± 3.92 years, respectively. Mean scale scores were 81.5 ± 17.9 for appearance, 86.8 ± 12.4 for symptoms, and 79.3 ± 25.7 for psychosocial impact. Higher patient dissatisfaction with scar appearance correlated with more scar-related symptoms (r = 0.389; p = 0.028) and a greater psychosocial impact (r = 0.725; p < 0.001). SCAR-Q scales did not significantly correlate with age at surgery, age at survey completion, type of synostosis, or type of surgery; however, female patients reported lower mean appearance (65.4 vs. 86.0; p = 0.012) and psychosocial impact (57.3 vs. 85.5; p = 0.010) scores when compared to their male counterparts. CONCLUSIONS: It is vital that surgeons discuss patients' aesthetic satisfaction following craniosynostosis surgery in order to appropriately address and limit deleterious, long-term physical and psychosocial outcomes.
RESUMO
Per- and polyfluoroalkyl substances (PFAS) are artificial chemicals extensively utilized in everyday products, and numerous cross-sectional epidemiological studies consistently link PFAS exposure with lipid profiles across diverse populations and age groups. In longitudinal studies, the findings also indicate a positive correlation between PFAS and lipid profiles; however, this association remains unexplored in adolescents and young adults. Notably, previous research has predominantly focused on conventional lipid biomarkers, with limited exploration of the relationship between PFAS and diverse lipoprotein subfractions. Furthermore, there is a lack of comprehensive investigation into the temporal trends in PFAS concentrations in Taiwan. To address this research gap, we conducted a prospective study following 592 adolescents and young adults (12-30 years old at enrollment) from the YOung TAiwanese Cohort (YOTA) over a duration of 10 years. During the follow-up period, we measured 11 types of PFAS and various lipid profile biomarkers (low-density lipoprotein cholesterol (LDL-C), small dense LDL-C (sdLDL-C), low-density lipoprotein triglyceride (LDL-TG), high-density lipoprotein cholesterol (HDL-C), HDL3-C, lipoprotein(a), triglyceride). Our results revealed a general decline in PFAS concentrations in the study population. Regarding the correlation between the average levels (averaged across the initial and second tracking periods) of PFAS and lipid profiles (during the second tracking period), we observed positive correlations with total cholesterol and LDL-C for perfluorononanoic acid (PFNA), perfluoroundecanoic acid (PFUdA), perfluorododecanoic acid (PFDoA), N-methylperfluorooctane sulfonamide acetic acid (N-MeFOSAA), and the sum of PFAS (sum of the 11 kinds of PFAS). Additionally, average levels of PFUdA, N-MeFOSAA, and the sum of PFAS exhibited positive associations with sdLDL-C. This study unveiled an overall decrease in PFAS concentrations and underscores a potential link between PFAS exposure and adverse changes in lipid profiles among young populations, emphasizing the need for further exploration into the mechanisms of PFAS on lipid metabolism and atherosclerosis.
RESUMO
BACKGROUND AND AIMS: Active aging is the process through which people strive to maintain wellbeing when growing old. Addressing the lack of research on active aging in the context of housing, the aim was to describe active aging among people aged 55 and older considering relocation and investigate whether perceived housing moderates the relationship between functional limitations and active aging. METHODS: We utilized cross-sectional data from a sub-sample (N = 820; mean age = 69.7; 54% women) of the Prospective RELOC-AGE. Functional limitations were reported using 10 dichotomous questions. Active aging was assessed with the University of Jyvaskyla Active Aging Scale (UJACAS; 17 items, self-rated for four perspectives). Perceived housing was self-rated with four usability questions and meaning of home (MOH; 28 items). Cross-sectional associations and interactions were analysed using linear regression models, adjusting for gender and educational level. RESULTS: Each functional limitation decreased the active aging score by almost five points (p < 0.001). Usability did not moderate that relationship while MOH significantly attenuated the association between functional limitations and active aging (p = 0.039). Those with high MOH had two points less decrease in active aging score compared to those with low MOH. DISCUSSION AND CONCLUSIONS: Having a home with more personal meaning attached to it seems to provide more ability and opportunity for meaningful activities, thus supporting active aging despite functional limitations. This sheds new light on the known association between MOH and different aspects of wellbeing in old age and has relevance for theory development, housing policies and housing counselling targeting younger older adults.

BACKGROUND: Despite significant changes in healthcare, work practices, and leisure activity, the proposed precipitating factors for abdominal wall hernias have remained largely unchanged for almost two centuries. We aimed to investigate if there have been shifts in these factors over time by examining patients' perception of precipitating factors for abdominal wall hernia development. This study was conducted in the Royal College of Surgeons In Ireland Department of Surgery, Connolly Hospital, Blanchardstown, Dublin, where patients with abdominal wall hernias completed a questionnaire . RESULTS: A total of 277 patients (mean age 55.7; 85.6% male) with abdominal wall hernia completed the questionnaire (66.1% inguinal; 10.8% umbilical; 6.9% paraumbilical; 10.5% epigastric; 3.2% incisional; 1.4% femoral, and 1.1% port-site). One hundred and twenty patients (43.3%) believed their hernia was due to lifting, 71 (25.6%) cited gym activity and 17 (6.1%) cited other sporting activities as the precipitating factor. Traditional factors - chronic cough and constipation - were cumulatively cited only by 11 patients (4.0%), while prostatic obstruction was not cited by any. CONCLUSION: This study suggests that fitness pursuits may be an increasing contributor to the development of abdominal wall hernia. Greater attention should be paid to the proper use of gym equipment to minimise the risk of hernia development.
RESUMO
BACKGROUND: Proximal humerus fractures are primarily common in the old age group. The appropriate approach to managing such displaced and comminuted fracture patterns is often questionable. Hence, this study was conducted to assess the functional outcome of proximal humerus fractures following treatment with a proximal humerus locking plate and to assess the frequency of complications in such patients. METHODOLOGY: In this robust study, 33 cases of proximal humerus fractures underwent surgical management at a prestigious teaching hospital from February 2021 to August 2022 utilizing a proximal humerus internal locking system (PHILOS) plate. The NEER classification was employed to categorize the fractures, and the NEER score was used for functional assessment. It's crucial to note that individuals with pathological fractures, associated injuries in the ipsilateral limb, nerve injuries, and cases of open fracture were rigorously excluded from the study. RESULTS: The mean age was 47 ± 5.2 years. Based on NEER's classification, the distribution of fractures was as follows: two-part fractures accounted for 18.18% (n = 6) of cases, three-part fractures for 54.54% (n = 18) of cases, and four-part fractures for 27.27% (n = 9) of cases. A history of road traffic accidents and falls was reported in 54.54% (n = 18) and 45.45% (n = 15) of cases, respectively. Functional outcome assessment utilizing NEER's score revealed a minimum score of 48 and a maximum of 96, with an average score of 82.96 ± 12.73. Notably, 39% of patients demonstrated excellent results, 27% exhibited satisfactorily, 21% manifested unsatisfactorily, and 12.12% presented failure outcomes. Of the 33 operated cases, 81.8% (n = 27) exhibited no complications during follow-up. The predominant complication observed was shoulder stiffness (9.09%, n = 3), followed by Varus mal-union (6.06%, n = 2), and superficial surgical site infection (3.03%, n = 1), managed with debridement and antibiotics leading to subsequent resolution. CONCLUSIONS: Managing proximal humerus fractures has consistently posed a formidable challenge. Our study indicates that using the PHILOS plate represents a reliable option for addressing such fractures. This plate provides sturdy fixation, facilitates early mobilization, and culminates in exceptional functional outcomes. The insights gained from this study can inform clinical decision-making and guide orthopedic surgeons in selecting the appropriate treatment strategy for proximal humerus fracture patients.
RESUMO
PURPOSE: Limited research has examined the combined effects of psychosocial and material adversities experienced in childhood during adolescence, a sensitive period of rapid social, emotional, and cognitive development. We investigated the interaction effect of adverse childhood experiences (ACEs) and socioeconomic circumstances (SECs) during childhood on emerging self-reported depressive symptomatology among 13-year-old Portuguese adolescents. METHODS: We utilized data from 4,280 participants in the Generation XXI birth cohort, collected during the baseline (2005-2006), third (2016-2017), and fourth waves (2018-2020). Adjusted odds ratios and 95% confidence intervals (CIs) were obtained from binary logistic regression analyses to estimate the likelihood of depressive symptoms based on exposure to ACEs and adverse family SECs. The interaction effect of ACEs and SECs was evaluated in terms of departure from additive and multiplicative models. RESULTS: Adolescents who reported experiences of abuse, school-related problems, and household dysfunction, as well as those from less advantaged family SECs at age 10, were more likely to report moderate to severe depressive symptoms at age 13, compared to their more affluent counterparts. We observed a significant additive interaction between low household income and abuse in the development of moderate to severe depressive symptoms [relative excess risk due to interaction, 0.69, 95% CI: 0.11, 1.26]. This interaction remained statistically significant on a multiplicative scale [OR = 1.61, 95% CI: 0.99, 2.69]. DISCUSSION: ACEs and low family SECs during the first decade of life are associated with an elevated risk of moderate to severe depressive symptoms in adolescence.
RESUMO
Background: d-alanine administration prevented kidney damage in a murine acute kidney injury model. Further data are needed on the influence of d-alanine on kidney function in humans. Objective: This study investigated the effects of d-alanine intake on amino acid metabolism and kidney function in healthy volunteers. Methods: This multicenter pilot study randomly assigned individuals from the general Japanese population to receive 3 g or 6 g of d-alanine intake per day for 7 d in a 1:1 ratio. The primary endpoint was the mean change in plasma and urine d-alanine levels from baseline to 7 d after intake. The secondary endpoints were mean changes in kidney function and other clinical factors. Safety was assessed by evaluating adverse events and clinical parameters. Results: We randomly assigned 24 participants to the 3-g (n = 12) and 6-g d-alanine (n = 12) groups. The mean baseline estimated glomerular filtration rate (eGFR) was 73 mL/min/1.73 m2. The mean plasma d-alanine concentration increased from baseline by 77.5 ± 34.3 and 192.1 ± 80.9 nmol/mL in the 3-g and 6-g d-alanine groups (both p < 0.0001), respectively, in a dose-dependent manner (between-group difference: 114.6 nmol/mL; 95% CI: 62.1-167.2; P = 0.0002). A similar increase was observed for the urine d-alanine to creatinine ratio. The mean eGFR was elevated by 5.7 ± 8.8 mL/min/1.73 m2 in the 6-g d-alanine group (P = 0.045) but did not significantly change in the 3-g d-alanine group. Nonserious adverse events were reported in 11 participants. Conclusions: d-alanine intake increased plasma and urine d-alanine levels and was well tolerated in participants with normal kidney function. These results will be useful in future trials investigating the effects of d-alanine intake on kidney disease progression in patients with chronic kidney disease.This trial was registered at the UMIN Clinical Trials Registry as UMIN000051466.
RESUMO
INTRODUCTION: Essential tremor (ET) patients may exhibit a variety of non-motor features, including cognitive decline and depressive symptoms. Studies of several neurodegenerative diseases link depression to cognitive decline, suggesting depression is an early marker of dementia. We examined whether baseline depressive symptoms predict incident dementia in elders with ET. METHODS: Hundred and forty-one ET cases aged 70 years or older at baseline, enrolled in a prospective study of cognitive performance, took part in evaluations at baseline and at 18, 36, 54, and 72 months. Participants completed the Geriatric Depression Scale (GDS), a 30-item self-report measure of depressive symptoms, and a battery of neuropsychological tests and functional assessments, from which we derived cognitive diagnoses at each evaluation. Cox proportional hazards regression equations determined incident dementia risk based on participants' baseline depression scores. RESULTS: Mean baseline age was 81.5 ± 6.7 years. Higher baseline GDS scores were associated with increased risk of dementia in an unadjusted model (hazards ratio [HR] = 1.11, 95% confidence interval [CI] = 1.02-1.20, p = 0.01) and after controlling for baseline age, education, number of medications, and tremor onset age (HR = 1.13, 95% CI = 1.02-1.25, p = 0.02). CONCLUSION: Baseline depression scores predicted incident dementia in elders with ET. With each one-point increase in baseline depression score, there was a 13% increase in incident dementia risk. Given the published data that reported depression may be twice as high in elders with ET compared to controls, this association is particularly worrisome in the ET population.
RESUMO
Per- and polyfluoroalkyl substances (PFAS) constitute a group of synthetic chemicals extensively utilized across various commonplace products. PFAS are known to have various toxic effects on human health. The relationship between PFAS exposure and erythrocytes has been a subject of interest in epidemiological research, but so far, only limited cross-sectional studies have investigated. Additionally, the role of erythrocyte related nutrition indicators on PFAS-induced changes in erythrograms has not been explored. To fill these knowledge gaps, we launched a longitudinal study over a decade, tracking 502 adolescents and young adults aged 12 to 30 from the YOung TAiwanese Cohort (YOTA). Our analysis encompassed 11 types of plasma PFAS, as well as erythrograms and serum levels of ferritin, transferrin saturation, vitamin B12, and folate. Our examination unveiled positive associations between specific average levels of PFAS compounds, including linear perfluorooctanoic acid (PFOA), branched perfluorooctane sulfonic acid (PFOS), perfluorononanoic acid (PFNA), and perfluorohexane sulfonic acid (PFHxS), and transferrin saturation. Furthermore, linear PFOA and both linear and branched PFOS were negatively correlated with vitamin B12 levels. Specifically, we observed that the average linear PFOA demonstrated positive correlations with mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH), while average PFNA also exhibited positive associations with hemoglobin (Hb) and hematocrit (Hct) in a multiple linear regression model. Subsequent analysis revealed noteworthy interactions between vitamin B12 and PFNA, as well as folate and PFNA, in the context of their impact on Hb, Hct, and PFNA relationships. Additionally, an interaction with transferrin saturation was identified in the correlation between Hct and PFNA. These findings suggest a plausible link between PFAS exposure and erythrograms among young populations, underscoring the potential involvement of iron status, vitamin B12, and folate in this association. Further studies are imperative to elucidate the precise effects of PFAS on erythrocyte in human subjects.
RESUMO
OBJECTIVE: To evaluate associations of fish oil supplementation and plasma omega 3 polyunsaturated fatty acids (n-3 PUFAs) with risks of macrovascular and microvascular complications among people with type 2 diabetes, and to further explore the potential mediating role of metabolism-related biomarkers. RESEARCH DESIGN AND METHODS: This study included 20,338 participants with type 2 diabetes from UK Biobank. Diabetic complications were identified through hospital inpatient records. RESULTS: During 13.2 years of follow-up, 5,396 people developed macrovascular complications, and 4,868 people developed microvascular complications. After multivariable adjustment, hazard ratios (HRs) and 95% confidence intervals (CIs) for patients with fish oil were 0.90 (0.85, 0.97) for composite macrovascular complications, 0.91 (0.84, 0.98) for coronary heart disease (CHD), 0.72 (0.61, 0.83) for peripheral artery disease; and 0.89 (0.83, 0.95) for composite microvascular complications, 0.87 (0.79, 0.95) for diabetic kidney disease, and 0.88 (0.80, 0.97) for diabetic retinopathy. In addition, higher n-3 PUFA levels, especially docosahexaenoic acid (DHA), were associated with lower risks of macrovascular and microvascular complications. Comparing extreme quartiles of plasma DHA, the HRs (95% CIs) were 0.68 (0.57, 0.81) for composite macrovascular complications, 0.63 (0.51, 0.77) for CHD; and 0.59 (0.38, 0.91) for diabetic neuropathy. Moreover, biomarkers including lipid profile and inflammation collectively explained 54.4% and 63.1% of associations of plasma DHA with risks of composite macrovascular complications and CHD. CONCLUSIONS: Habitual use of fish oil supplementation and higher plasma n-3 PUFA levels, especially DHA, were associated with lower risks of macrovascular and microvascular complications among individuals with type 2 diabetes, and the favorable associations were partially mediated through improving biomarkers of lipid profile and inflammation.
RESUMO
PURPOSE: Evaluation of the effectiveness of pneumatic vitreolysis in disrupting vitreomacular traction in our own cohort of patients. METHODOLOGY: Prospective follow-up of 21 eyes of 18 patients with focal VMT (adhesion width < 1500 µm) who underwent intravitreal injection of 0.3 ml of 100% perfluoropropane between January 2015 and December 2020. The patients were observed for 90 days. RESULTS: Release of VMT was achieved on the 28th day of observation in 15 out of 21 eyes (71.4%), and by the 90th day in 19 out of 21 eyes (90.5%). The average width of adhesion in our patients was 382 µm (±212 µm). Average best corrected visual acuity in our cohort was initially 0.77 (±0.21), after 28 days 0.74 (±0.30), and after 3 months 0.82 (±0.21). At the end of the follow-up period, we did not observe a statistically significant improvement in vision. Macular holes developed in two eyes, but spontaneously closed within 1 month of observation, and no more complications were observed in the cohort. CONCLUSION: Pneumatic vitreolysis by intravitreal injection of C3F8 gas is an effective and inexpensive option for the management of symptomatic vitreomacular traction. The incidence of serious adverse events in our follow-up was significantly lower than in recently published series. The method of management should be selected individually according to the parameters of adhesion, macular hole and associated ocular pathologies.

BACKGROUND: The diagnosis of intensive care unit (ICU)-acquired weakness (ICUAW) and critical illness neuromyopathy (CINM) is frequently hampered in the clinical routine. We evaluated a novel panel of blood-based inflammatory, neuromuscular, and neurovascular biomarkers as an alternative diagnostic approach for ICUAW and CINM. METHODS: Patients admitted to the ICU with a Sequential Organ Failure Assessment score of ≥ 8 on 3 consecutive days within the first 5 days as well as healthy controls were enrolled. The Medical Research Council Sum Score (MRCSS) was calculated, and motor and sensory electroneurography (ENG) for assessment of peripheral nerve function were performed at days 3 and 10. ICUAW was defined by an MRCSS < 48 and CINM by pathological ENG alterations, both at day 10. Blood samples were taken at days 3, 10, and 17 for quantitative analysis of 18 different biomarkers (white blood cell count, C-reactive protein, procalcitonin, C-terminal agrin filament, fatty-acid-binding protein 3, growth and differentiation factor 15, syndecan 1, troponin I, interferon-γ, tumor necrosis factor-α, interleukin-1α [IL-1α], IL-1ß, IL-4, IL-6, IL-8, IL-10, IL-13, and monocyte chemoattractant protein 1). Results of the biomarker analysis were categorized according to the ICUAW and CINM status. Clinical outcome was assessed after 3 months. RESULTS: Between October 2016 and December 2018, 38 critically ill patients, grouped into ICUAW (18 with and 20 without) and CINM (18 with and 17 without), as well as ten healthy volunteers were included. Biomarkers were significantly elevated in critically ill patients compared to healthy controls and correlated with disease severity and 3-month outcome parameters. However, none of the biomarkers enabled discrimination of patients with and without neuromuscular impairment, irrespective of applied classification. CONCLUSIONS: Blood-based biomarkers are generally elevated in ICU patients but do not identify patients with ICUAW or CINM. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02706314.
RESUMO
OBJECTIVE: This study explores the impact of leisure activity and the association between childhood starvation and the risk of diabetes in older Chinese adults. DESIGN: Prospective cohort study based on the Chinese Longitudinal Healthy Longevity Study (CLHLS), a nationwide cohort study in China. SETTING AND PARTICIPANTS: A total of 4637 older adults aged ≥65 years, all with documented diabetes history, experiences of childhood starvation, and participation in leisure activities were recruited. METHODS: Childhood starvation exposure was assessed via self-reported responses from a structured questionnaire. The leisure activities were measured by 9 distinctive components and categorized into 3 distinct categories: productive activity, recreational activity, and sedentary activity. Diabetes status was determined by self-reported, physician-diagnosed cases during the follow-up period. Nonparametric survival models were employed for analysis. RESULTS: Over an average follow-up period of 4.3 years, 215 of 4637 participants (4.6%) reported a confirmed diagnosis of diabetes. Nonparametric survival models showed that those reporting childhood starvation had a higher risk of late-life diabetes [hazard ratio (HR) 1.72, 95% CI 1.21-2.44]. Engaging in productive activity (HR 0.90, 95% CI 0.83-0.99) and recreational activity (HR 0.88, 95% CI 0.77-1.00) was linked with a reduced risk of late-life diabetes. Sedentary activity did not show a significant effect. Further analysis highlighted the interactions effects of leisure activities on diabetes risk across different demographic and historical exposure subgroups. CONCLUSIONS AND IMPLICATIONS: Engaging in productive and recreational leisure activities was inversely associated with the risk of diabetes in older adults who experienced childhood starvation. Promoting such activities could be beneficial in mitigating long-term diabetes risk related to early-life nutritional deficiencies.
RESUMO
AIM: The constellation of cardiovascular disease (CVD) risk factors greatly impacts the lifetime risk (LTR) of incident CVD, but the LTR has not been thoroughly evaluated in the Japanese population. METHODS: We conducted a prospective study involving a total of 25,896 individuals 40-69 years old without a history of CVD in 1995 (Cohort I) and 1993-1994 (Cohort II) in Japan. CVD risk factors (blood pressure, non-high-density lipoprotein [HDL] cholesterol levels, smoking status, and glucose concentrations) were used to stratify them by risk. The sex-specific LTR of incident coronary heart disease, stroke, atherosclerotic CVD, and total CVD were estimated for participants 45 years old in the 4 risk categories with the cumulative incidence rate, adjusting for the competing risk of death. RESULTS: We found apparent differences in the LTR of total CVD according to the risk stratification. Individuals with ≥ 2 of the risk factors of blood pressure ≥ 140/90 mmHg or treated, non-HDL cholesterol level ≥ 170 mg/dL or treated, current smoker, and diabetes had substantially higher adjusted LTRs of CVD than those in other groups, with a LTR of 26.5% (95% confidence interval, 24.0%-29.0%) for men and 15.3% (13.1%-17.5%) for women at 45 years. The LTR of incident stroke was the highest among CVDs, and the presence of hypertension and diabetes mellitus strongly influenced the LTR of total CVD. CONCLUSION: The impact of risk accumulation on LTR of CVD was greater in men, and 1 in 4 men with ≥ 2 major risk factors at 45 years of age developed CVD in their lifetime.
RESUMO
Type 2 diabetes mellitus (T2DM) is a metabolic disorder characterized by hyperglycemia resulting from defects in insulin secretion and/or insulin action. Increasing evidence suggests that inflammation played an important role in the pathogenesis of T2DM. Prospective studies on the link between immunoglobulins concentrations and the risk of T2DM in adults are limited. We developed a cohort study including 7,093 adults without T2DM history. The incidence of T2DM was 16.45 per 1,000 person-years. Compared with the lowest quartiles, the hazard ratios (95% confidence intervals) of T2DM for the highest quartiles of IgG, IgE, IgM and IgA were 0.64 (0.48-0.85), 0.94 (0.72-1.23), 0.68 (0.50-0.92) and 1.62 (1.24-2.11) (P for trend was < 0.01, 0.84, 0.02 and < 0.0001), respectively, suggesting that serum IgG and IgM concentrations were inversely associated with the incidence of T2DM, and IgA levels were positively associated with the risk of T2DM in a general adult population.
