Usefulness of virtual scale endoscope for early gastrointestinal lesions.

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.

Leveraging real-world data to predict cancer cachexia stage, quality of life, and survival in a racially and ethnically diverse multi-institutional cohort of treatment-naïve patients with pancreatic ductal adenocarcinoma.

Introduction: Cancer-associated cachexia (CC) is a progressive syndrome characterized by unintentional weight loss, muscle atrophy, fatigue, and poor outcomes that affects most patients with pancreatic ductal adenocarcinoma (PDAC). The ability to identify and classify CC stage along its continuum early in the disease process is challenging but critical for management. Objectives: The main objective of this study was to determine the prevalence of CC stage overall and by sex and race and ethnicity among treatment-naïve PDAC cases using clinical, nutritional, and functional criteria. Secondary objectives included identifying the prevalence and predictors of higher symptom burden, supportive care needs, and quality of life (QoL), and examining their influence on overall survival (OS). Materials and methods: A population-based multi-institutional prospective cohort study of patients with PDAC was conducted between 2018 and 2021 by the Florida Pancreas Collaborative. Leveraging patient-reported data and laboratory values, participants were classified at baseline into four stages [non-cachexia (NCa), pre-cachexia (PCa), cachexia (Ca), and refractory cachexia (RCa)]. Multivariate regression, Kaplan Meier analyses, and Cox regression were conducted to evaluate associations. Results: CC stage was estimated for 309 PDAC cases (156 females, 153 males). The overall prevalence of NCa, PCa, Ca, and RCa was 12.9%, 24.6%, 54.1%, and 8.4%, respectively. CC prevalence across all CC stages was highest for males and racial and ethnic minorities. Criteria differentiated NCa cases from other groups, but did not distinguish PCa from Ca. The most frequently reported symptoms included weight loss, fatigue, pain, anxiety, and depression, with pain significantly worsening over time. The greatest supportive care needs included emotional and physical domains. Males, Black people, and those with RCa had the worst OS. Conclusions: Using clinical, nutritional, and functional criteria, nearly one-quarter of the PDAC cases in our diverse, multi-institutional cohort had PCa and 62.5% had Ca or RCa at the time of diagnosis. The PCa estimate is higher than that reported in prior studies. We recommend these criteria be used to aid in CC classification, monitoring, and management of all incident PDAC cases. Findings also highlight the recommendation for continued emotional support, assistance in alleviating pain, and supportive care needs throughout the PDAC treatment journey.

Associations of very low Lipoprotein(a) levels with risks of new-onset diabetes and non-alcoholic liver disease.

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.

Increase in Intraoperative Intraocular Pressure in the Prone Position.

Introduction: This study aimed to measure the intraocular pressure (IOP) of patients undergoing open surgery in the supine position (control group) and spine surgery in the prone position (spine group) to clarify IOP range and change by posture, determine the risk factors for increased IOP in the prone position, and reduce visual complications after surgery in the prone position. Methods: A prospective cohort study was conducted in healthy adults (34-83 years of age) with an American Society of Anesthesiologists classification I/II. The spine group was examined for IOP, anterior chamber angle (ACA), and fundus findings the day prior to surgery. On the day of surgery, IOP measurements were taken at fixed time points: immediately after intubation; at 0.5, 1, and 2 h after intubation; at suture closure; and at the end of surgery in the control group. In the spine group, they were taken immediately after intubation; at 0.5, 1, and 2 h after prone position; at suture closure; and immediately and 5 min after returning to the supine position. The risk factors for increased IOP in the prone position were examined. Results: The control group showed no significant changes in IOP within the normal range (<20 mmHg) during surgery. In the spine group, IOP was higher at each time point than immediately after intubation. IOP increased sharply above the normal range within 1 h after changing from the supine to the prone position and continued to gradually increase until suture closure. IOP decreased 5 min after the patient returned to the supine position. ACA, body mass index, blood loss, time in the prone position, and operative time were not risk factors for increased IOP in the prone position. Conclusions: Patients were constantly exposed to above-normal IOP during prone spinal surgery. However, neither group reported visual impairment. No risk factors were identified for increased IOP in the prone position.

One-Year Clinical Outcomes Following Mechanical Thrombectomy for Deep Vein Thrombosis: A CLOUT Registry Analysis.

Background: Mechanical thrombectomy is a promising treatment option for deep vein thrombosis; however, long-term data are lacking. Here, we report for the first time the 1-year clinical outcomes from the completely enrolled ClotTriever Outcomes (CLOUT) registry evaluating mechanical thrombectomy with the ClotTriever System (Inari Medical). Methods: The CLOUT registry (NCT03575364) is a prospective, multicenter, single-arm study that enrolled 500 patients with proximal lower extremity deep vein thrombosis. Prespecified 1-year outcomes include Villalta score and corresponding postthrombotic syndrome (PTS) severity, duplex ultrasound findings of patency (defined as the presence of flow with normal or partial compressibility), Revised Venous Clinical Severity Score, and quality of life (QoL). Results: In CLOUT, the median age was 61.9 years and 50.5% of patients were women. A total of 310 patients completed the 1-year visit. The 1-year PTS rate (Villalta score ≥ 5) was 19.3% and the moderate-to-severe PTS rate (Villalta score ≥ 10) was 8.8%. Median Villalta score decreased from 9.0 (IQR, 5.0-14.0) at baseline to 1.0 (IQR, 0.0-4.0) at 1 year (P < .0001). Similar rates of PTS and moderate-to-severe PTS were observed among limbs assessed at all study time points. Patency was observed in 94.2% of limbs. Median Revised Venous Clinical Severity Score was 6.0 (IQR, 3.0-9.0) at baseline and 3.0 (IQR, 1.0-4.0) at 1 year (P < .0001). Additionally, 90.4% of patients experienced improvements in QoL. Conclusions: One-year outcomes from the CLOUT registry demonstrate low PTS rates and preserved patency accompanied by improved symptom relief and QoL. Study follow-up through 2 years is ongoing.

Patient's Perception of the Role of Gym Activity in Abdominal Wall Herniation in Adults: A Prospective Study.

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.

Vitamin B12 status and the risk of developing sepsis in patients with bacterial infection: a prospective observational cohort study.

BACKGROUND: Data have shown that vitamin B12 has immunomodulatory effects via different pathways, which could influence the pathophysiology of sepsis. The objective of this study was to investigate whether vitamin B12 levels, assessed by the measurement of holotranscobalamin (HTC), total vitamin B12 (B12), and methylmalonic acid (MMA, which accumulates in case of B12 deficiency), are associated with the development of sepsis in patients with onset of bacterial infection. METHODS: This was a single-center, prospective observational pilot study. Adult patients who presented to the emergency department with bacterial infection confirmed by a positive microbiological culture result were included in the study and followed up for 6 days to assess whether they developed sepsis or not. The primary objective was to compare HTC concentration in patients who developed sepsis to those who did not develop sepsis. Secondary objectives were the evaluation of B12 and MMA concentrations in those two groups. Multiple logistic regression models were used, with presence of sepsis as the outcome variable, and HTC, B12, and MMA concentrations as predictor variables, separately, and adjusted for potential confounders. RESULTS: From 2019 to 2022, 2131 patients were assessed for eligibility, of whom 100 met the inclusion criteria. One patient was excluded from the analysis due to missing data. Of the 99 patients, 29 developed sepsis. There was no evidence for an association between HTC or B12 concentration and the development of sepsis (OR 0.65, 95% CI 0.31-1.29, p = 0.232, OR 0.84, 95% CI 0.44-1.54, p = 0.584, respectively). There was an association between MMA concentration and the development of sepsis, with a positive effect, i.e. with increasing MMA, the odds for sepsis increased (OR 2.36, 95% CI 1.21-4.87, p = 0.014). This association remained significant when adjusted for confounders (OR 2.72, 95% CI 1.23-6.60, p = 0.018). CONCLUSIONS: Our study found an association between elevated MMA concentration and the development of sepsis. We did not find an association between HTC and B12 concentrations and the development of sepsis. Further, larger studies are warranted, as it could lead to interventional trials investigating whether B12 supplementation provides a clinical benefit to patients with infection or sepsis. TRIAL REGISTRATION: The study was registered on ClinicalTrials.gov under the identifier NCT04008446 on June 17, 2019.

Examining a decade-long trend in exposure to per- and polyfluoroalkyl substances and their correlation with lipid profiles: Insights from a prospective cohort study on the young Taiwanese population.

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.

The prevalence and predictors of discharge opioid overprescribing in opioid-naïve patients after breast, gynecologic, and head and neck cancer surgery: a prospective cohort study.

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.

Associations Of Vitamin D-Related Biomarkers With Hypertension And The Renin-Angiotensin System In Men And Women.

BACKGROUND: Vitamin D may prevent the development of hypertension through down-regulation of renin-angiotensin system. However, epidemiologic studies assessing the interrelation of vitamin D-related biomarkers with hypertension are sparse. METHODS: We examined the prospective associations between vitamin D-related biomarkers and risk of hypertension in a nested case-control study. In each of the Women's Health Study (WHS) and Physicians' Health Study (PHS) II, 500 incident hypertension cases and 500 age and race matched controls were randomly selected. Baseline plasma 25(OH)-vitamin D [25(OH)D], parathyroid hormone (PTH), and total renin concentrations were measured. RESULTS: Among controls, 25(OH)D and PTH were inversely correlated, but neither was correlated with total renin. In the crude model, there was a trend of association between increasing quintiles of 25(OH)D and lower risk of hypertension in women, with relative risks and 95% CIs of 1.00, 1.24 (0.84-1.83), 0.82 (0.53-1.25), 0.75 (0.48-1.16), and 0.81 (0.52-1.27) (p, trend: 0.07). Adjustment for body mass index and other hypertension risk factors eliminated this association (RR of 5th quintile: 1.03). No associations were found in men. Baseline PTH and ratio of 25(OH)D to PTH were not associated with risk of hypertension in women or men. When men and women were included in the same model, vitamin D insufficiency (defined as 25(OH)D <20 ng/mL) also was not associated with increased risk of hypertension. No interactions were found across subgroups. CONCLUSIONS: Our study found no association of baseline plasma 25(OH)D or PTH with risk of hypertension or total renin concentration in middle-aged and older men and women.

Longitudinal assessment of female carriers of choroideremia using multimodal retinal imaging.

BACKGROUND/AIMS: Female choroideremia carriers present with a spectrum of disease severity. Unlike in men, the rate of disease progression has not been well characterised in carriers. This longitudinal study aimed to determine the rate of retinal degeneration in choroideremia carriers, using multimodal imaging and microperimetry. METHODS: Choroideremia carriers previously seen at Oxford Eye Hospital (United Kingdom) between 2012 and 2017 returned for testing between 2015 and 2023, providing up to 11 years' follow-up data. Participants had optical coherence tomography, fundus-tracked microperimetry and fundus autofluorescence (FAF) imaging performed. RESULTS: Thirty-four eyes of 17 choroideremia carriers were examined using multimodal imaging. Median age was 44 (range: 15-73) years at baseline and median follow-up duration was 7 (range: 1-11) years. At baseline, phenotype was classified as fine (n=5 eyes), coarse (n=13 eyes), geographic (n=12 eyes) or male pattern (n=4 eyes). Thirteen patients showed no change in phenotype classification, four showed slight changes associated with choroideremia-related retinal degeneration. Despite this, carriers with severe retinal phenotypes had a statistically significant decline in average retinal sensitivity (-0.7 dB and -0.8 dB per year, respectively, p<0.001), area of geographic loss defined by FAF (+2.5 mm2 and +3.7 mm2 per year, respectively, p<0.001) and thinning of the photoreceptor complex (up to -2.8 microns and -10.3 microns per year, p<0.001). CONCLUSION: Choroideremia carriers, particularly those with severe retinal phenotypes, exhibit progressive retinal degeneration, as evident by multimodal imaging biomarkers and functional testing. Clinicians should not rely on retinal severity classification alone to assess disease progression.

Ankle-GO score is associated with the probability of becoming coper after lateral ankle sprain: a 1-year prospective cohort study.

OBJECTIVE: To analyse the association between Ankle-GO score during the return to sport process and the probability of becoming a coper 1 year after lateral ankle sprain (LAS). Copers were defined as patients returning to their preinjury sport without loss of function and reporting no episodes of reinjury or giving-way. METHODS: Two months after a LAS, patients performed the Ankle-GO assessment which includes a cluster of four functional tests and two self-reported questionnaires for a maximum score of 25 points. One year after injury, participants were classified as copers or non-copers. Eight potential predictive variables associated with coper status were compared between the groups. Receiver operating characteristic curves (area under the curve (AUC)) and multivariable logistic regression models with OR and 95% CIs were used to determine the association of potential factors, including the Ankle-GO score, with copers. RESULTS: 64 patients (56% females; age 33.7±13.2 years) completed the Ankle-GO-GO at 2 months postinjury. At 1 year postinjury, 10 patients (15%) were lost to follow-up, and only 17 of 54 patients (31%) became copers. Two-month Ankle-GO score was higher among copers (9.9±4.9 points vs 6.9±3.7, p=0.015) and was associated with future coper status at 1 year (AUC=0.70). Patients with an Ankle-GO score above 11 points and male patients were more likely to become copers (OR=12.1; 95% CI 2.5 to 59, p=0.002 and OR=5.2; 95% CI 1.2 to 22.4, p=0.026, respectively). CONCLUSION: The Ankle-GO may help identify patients more likely to become copers within a year of injury. Those with low Ankle-GO scores and female patients should receive additional rehabilitation to increase the odds of becoming a coper.

Herpes zoster and long-term risk of subjective cognitive decline.

BACKGROUND: Herpes zoster (HZ), commonly known as "shingles," may contribute to cognitive decline through mechanisms such as neuroinflammation or direct neuronal injury. However, evidence on the longitudinal association between HZ and cognitive decline is conflicting and whether the risk differs by APOE ε4-carrier status has not been studied; prospective cohort studies on the association between HZ vaccination and cognitive decline are also lacking. METHODS: We included 149,327 participants from three large cohorts-the Nurses' Health Study (NHS), NHSII, and Health Professionals Follow-Up Study (HPFS)-to prospectively examine the association between HZ and subsequent subjective cognitive decline (SCD). Poisson regression was used to estimate the multivariable-adjusted relative risk (MVRR) of a 3-unit increment in SCD score according to years since HZ compared with participants with no history of HZ. RESULTS: Compared with individuals with no history of HZ, the MVRR (95% CI) of a 3-unit increment in SCD score was significantly and independently higher among individuals with a history of HZ, but the duration of time since HZ when the elevated risk of SCD was statistically significant differed among the cohorts. In NHS, HZ was associated with higher long-term risk of SCD; compared with individuals with no history of HZ, the MVRR (95% CI) of a 3-unit increment in SCD score was 1.14 (1.01, 1.32) for ≥ 13 years since HZ. In NHS II, HZ was associated with higher risk of SCD in both the short-term [MVRR 1.34 (1.18, 1.53) for 1-4 years] and long-term [MVRR 1.20 (1.08, 1.34) for ≥ 13 years since HZ]. In HPFS, an elevated risk of SCD was suggested across all time points. Among the subset of participants with information on APOE ε4, there was a suggestion that the association differed by APOE ε4 carrier status, but the results were not consistent between women and men. Among the subset of women with information on HZ vaccination, there was a suggestion that the long-term risk of SCD may be greater among women who were not vaccinated against HZ. CONCLUSIONS: Data from three large independent cohorts of women and men showed that HZ was associated with higher long-term risk of SCD, and the risk may differ by APOE ε4-carrier status.

Weight-adjusted waist index as a practical predictor for diabetes, cardiovascular disease, and non-accidental mortality risk.

BACKGROUND AND AIM: Identifying a more suitable marker among various measures of adiposity, demonstrating strong associations and predictive ability for clinical use, remains a topic of debate. Weight-adjusted waist index (WWI) has been proposed as a novel index of adiposity, yet its exploration is limited, especially in Chinese populations. This study seeks to examine the associations between body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHTR), weight-adjusted waist index (WWI), waist circumference divided by body mass to the power of 0.333 (WC/M0.333), visceral adiposity index (VAI), lipid accumulation product (LAP), and the incidence of diabetes, cardiovascular disease, and non-accidental mortality in Chinese populations. Furthermore, our goal is to compare the respective predictive values of these measures for these health outcomes. METHODS AND RESULTS: This prospective cohort study included 21,750 subjects with a 9-year follow-up period. Cox proportional hazard models were used to investigate the relationship between eight anthropometric indexes and the incidence of diabetes, cardiovascular disease, and non-accidental mortality. The predictive value of these eight indexes was compared using the area under the curve metric. Significant positive associations were found between WWI and the risk of diabetes. Using the first quartile (Q1) of WWI as the reference group, hazard ratios with 95% confidence intervals for the risk of diabetes were 1.58 (0.98-2.55) for Q2, 2.18 (1.34-3.35) for Q3, and 2.27 (1.41-3.67) for Q4. Significant associations were observed with the highest quartile of WWI for the risk of cardiovascular disease [Q2: HR 1.45 (95% CI 1.06-1.98); Q3: 1.33 (0.97-1.83); Q4: 1.55 (1.13-2.14)] and risk of non-accidental mortality [Q2: 0.94 (0.80-1.11); Q3: 1.24 (1.04-1.48); Q4: 1.44 (1.16-1.79)]. Receiver operating characteristic analysis revealed that WWI exhibited superior discrimination and accuracy in predicting cardiovascular disease and non-accidental mortality compared to other adiposity indexes (BMI, WC, WHR, WHTR, WC/M0.333, VAI, and LAP). CONCLUSION: WWI exhibited the most robust and consistent association with the incidence of cardiovascular disease and non-accidental mortality. Given its simplicity and widespread use, WWI emerges as a novel and practical predictor of diabetes, cardiovascular disease, and non-accidental mortality among the eight adiposity indexes investigated in this study.

Prognostic value of 24-hour cultivation of peritoneal fluid to distinguish complicated from uncomplicated acute appendicitis: a prospective cohort study.

BACKGROUND: The distinction between complicated and uncomplicated acute appendicitis (AA) is important as it guides postoperative antibiotic treatment. A diagnosis based on intraoperative findings is imprecise and standard cultivation of peritoneal fluid is generally time-consuming with little clinical benefit. The aim of this study was to examine if cultivation of peritoneal fluid in acute appendicitis could reliably detect bacteria within 24 h. METHODS: Patients older than 18 years undergoing laparoscopic appendectomy were prospectively enrolled at two surgical departments after informed consent was obtained. Periappendicular fluid was collected prior to appendectomy and sent for cultivation. Sensitivity, specificity and positive and negative predictive values were calculated with 95% confidence intervals (CIs) using 72-hour cultivation results as the gold standard. Patients with complicated AA as determined by the surgeon, received a three-day course of oral antibiotics. Postoperative infectious complications within 30 days after surgery were registered. RESULTS: From July 2020 to January 2021, 101 patients were included. The intraoperative diagnosis was complicated AA in 34 cases. Of these patients, six (17.6%) had bacteria cultured within 24 h after surgery, leading to a sensitivity of 60% and a specificity of 100%. The positive and negative predictive values were 1.00 and 0.96, respectively. Seven patients developed a postoperative infection (five superficial wound infections and two intra-abdominal abscess). In all cases with a positive cultivation result, the intraoperative diagnosis was complicated appendicitis and a postoperative course of antibiotics prescribed. CONCLUSION: Twenty-four-hour cultivation of the peritoneal fluid in acute appendicitis is a valid indicator for peritoneal bacterial contamination. Randomized studies are necessary to determine if this approach is suitable for targeting postoperative antibiotic treatment as a means to prevent overtreatment without increasing the risk of infectious complications.

Plateletcrit and absolute immature platelet count are not impacted by platelet transfusions: a single-centre prospective study.

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.

Using the SCAR-Q to Evaluate Morbidity of Scars in Craniosynostosis Repair.

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.

Trimethylamine N-oxide predicts cardiovascular events in coronary artery disease patients with diabetes mellitus: a prospective cohort study.

Background: Gut microbiota has significant impact on the cardio-metabolism and inflammation, and is implicated in the pathogenesis and progression of atherosclerosis. However, the long-term prospective association between trimethylamine N-oxide (TMAO) level and major adverse clinical events (MACEs) in patients with coronary artery disease (CAD) with or without diabetes mellitus (DM) habitus remains to be investigated. Methods: This prospective, single-center cohort study enrolled 2090 hospitalized CAD patients confirmed by angiography at Beijing Hospital from 2017-2020. TMAO levels were performed using liquid chromatography-tandem mass spectrometry. The composite outcome of MACEs was identified by clinic visits or interviews annually. Multivariate Cox regression analysis, Kaplan-Meier analysis, and restricted cubic splines were mainly used to explore the relationship between TMAO levels and MACEs based on diabetes mellitus (DM) habitus. Results: During the median follow-up period of 54 (41, 68) months, 266 (12.7%) developed MACEs. Higher TMAO levels, using the tertile cut-off value of 318.28 ng/mL, were significantly found to be positive dose-independent for developing MACEs, especially in patients with DM (HR 1.744, 95%CI 1.084-2.808, p = 0.022). Conclusions: Higher levels of TMAO are significantly associated with long-term MACEs among CAD patients with DM. The combination of TMAO in patients with CAD and DM is beneficial for risk stratification and prognosis.

A longitudinal assessment of major mouthwashes used in alleviating pain and xerostomia among advanced nasopharyngeal carcinoma patients receiving chemoradiotherapy.

OBJECTIVE: This longitudinal study aimed to evaluate the overall efficacy of mouthwashes in oral mucositis pain and mucositis xerostomia in advanced nasopharyngeal carcinoma (NPC) patients undergoing concurrent chemoradiotherapy (CCRT) at different phases throughout treatment. METHODS: A longitudinal study enrolled 79 advanced NPC subjects receiving CCRT. The subjects were interviewed prospectively three times over 7 weeks for pain and xerostomia scores based on the various types of mouthwash used. The median pain score difference and median xerostomia score difference were utilised to determine mouthwash superiority. RESULTS: Participants completed three interviews, during which 480 instances of mouthwash use were observed throughout different phases of the treatment period. The results showed that the median pain scores between mouthwashes differed significantly, H-Stat(3) = 30.0, 25.7 and 26.0, respectively, with p < 0.001 for all three interviews. The pain score reductions of lidocaine mouthwash (median = 2, interquartile range (IQR) = 3, 2 and 2.75 over the three interviews, respectively) were significantly higher than those of benzydamine and sodium bicarbonate mouthwashes. There were no significant differences between the studied mouthwashes in their xerostomia score reductions. CONCLUSIONS: Lidocaine mouthwash was superior in managing oral mucositis pain at all phases throughout the entire chemoradiotherapy treatment for advanced NPC patients. There was insufficient evidence to determine the preferred mouthwash for treating oral mucositis xerostomia.
