Heterogeneous depressive symptom trajectories among women with type 2 diabetes: findings from the Women's Interagency HIV Study.

Depression affects 33% of women with type 2 diabetes (T2D) and leads to increased risks of premature mortality. Fluctuation and variation of depressive presentations can hinder clinical identification. We aimed to identify and examine subgroups characterized by distinct depressive symptom trajectories among women with T2D. This retrospective analysis leveraged the Women's Interagency HIV Study data to identify depressive symptom trajectories based on the Center for Epidemiological Studies Depression scores (2014-2019) among women with and without HIV. Descriptive statistics characterized sample demographics (eg, age, race, income), clinical indices (eg, hemoglobin A1C [HbA1c], BMI, HIV status), and psychosocial experiences (eg, discrimination, social support, anxiety, pain). We used growth mixture modeling to identify groups defined by distinct depressive symptom trajectories and parametric and non-parametric tests to examine demographic, clinical, and psychosocial differences across subgroups. Among the 630 women included, the mean age was 50.4 (SD = 8.3) years, 72.4% identified as Black and non-Hispanic, and 68.2% were living with HIV. Five subgroups were identified and distinguished by severity and symptom type. Participants with lower incomes (P = .01), lower employment (P < .0001), lower social support (P = .0001), and experiences of discrimination (P < .0001) showed greater membership in threshold, moderate, and severe depressive subgroups. Subgroup membership was not associated with metabolic indices (BMI, HbA1c) or HIV status. Anxiety, pain, and loneliness (all P = .0001) were worse in subgroups with higher depressive symptoms. Among women with T2D, depressive symptom trajectories differ across clinical and social contexts. This study advances precision by delineating subgroups within a broad clinical category.

Psychological Symptom Cluster Severity Profiles Are Associated With Higher Levels of Stress and Worse Quality of Life in Postmenopausal Women With Breast Cancer.

Although common, the severity of the psychological symptom cluster (PSC) (ie, co-occurrence of anxiety, depression, fatigue, sleep disturbance) varies among women with breast cancer. In addition, the impact of various types of stress and other risk factors on its severity are understudied, and the influence of the PSC on quality of life (QOL) outcomes remains poorly characterized. To identify subgroups of postmenopausal women with breast cancer with distinct PSC severity profiles following surgery and evaluate whether these subgroups differed in terms of demographic and clinical characteristics, symptoms, social and posttraumatic stress, and QOL. Following surgery, 159 postmenopausal women with early-stage, hormone receptor-positive breast cancer completed assessments of anxiety, depression, fatigue, sleep disturbance, cognitive function, physical symptoms, stress, and QOL. Latent profile analysis was used to identify subgroups of women based on the severity of the prespecified PSC. Parametric and nonparametric tests were used to evaluate for subgroup differences. Three distinct PSC severity subgroups were identified (ie, Lower [71.7%], Moderate [23.9%], Higher [4.4%]). Compared with the Lower subgroup, the Moderate subgroup was less likely to have received prior radiation, and the Moderate and Higher subgroups had worse perceived cognitive function, higher symptom burden, higher posttraumatic stress, and lower QOL. Clinically relevant sleep disturbance was common across PSC subgroups. PSC severity is associated with higher posttraumatic stress and poorer QOL following breast surgery. Sleep disturbance is a common problem and may be undertreated. Assessments of posttraumatic stress and sleep disturbance are needed for timely intervention.

Latent Profile Analysis of Acute Stress Disorder Symptoms and Their Links to Individual Characteristics and Mental Health Among College Students During the Early COVID-19 Pandemic.

acute stress disorder (ASD) became prevalent among various populations during the COVID-19 pandemic, yet little research has examined the heterogeneity of ASD symptoms among college students. The purpose of this research was to explore subgroups of ASD symptoms using latent profile analysis (LPA) and to explore the predictors and mental health outcomes associated with these profiles. Using the person-centered method, we recruited 1198 college students (71.7% female) who self-reported their ASD, perceived social support, anxiety, depression, and life satisfaction from two Chinese universities following the COVID-19 outbreak. The LPA results found three ASD symptom severity profiles: low (56.7%), moderate (31.6%), and high (11.7%), particularly characterized by reexperiencing and arousal symptoms. This study found that students in the moderate and high ASD subgroups were more likely to be female, have lower socioeconomic status, belong to minority groups, report lower self-rated health, and perceive less social support compared to those in the low ASD subgroup. Furthermore, compared to the low and moderate ASD subgroups, the high ASD subgroup was linked to elevated anxiety and depression and lower life satisfaction. These findings underscore the significance of identifying specific ASD symptom subgroups to effectively target prevention and intervention efforts.

Interleukin-1 Beta rs16944 and rs1143634 and Interleukin-6 Receptor rs12083537 Single Nucleotide Polymorphisms as Potential Predictors of COVID-19 Severity.

Host genetic variation has been recognized as a key predictor of diverse clinical sequelae among severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected patients. Insights into the link between the Interleukin-6 receptor (IL-6R) and Interleukin-1 beta (IL-1β) genetic variation and severe coronavirus disease 2019 (COVID-19) are crucial for developing new predictors and therapeutic targets. We aimed to investigate the association of IL-6R rs12083537, IL-1β rs16944, and IL-1β rs1143634 SNPs with the severity of COVID-19. Our study was conducted on 300 COVID-19-negative individuals (control group) and 299 COVID-19-positive cases, classified into mild, moderate, and severe subgroups. Analyses of IL-1β (rs16944, rs1143634) and IL-6R (rs12083537) SNPs' genotypes were performed using qPCR genotyping assays. The IL-1β (rs16944) CC genotype and IL-6R (rs12083537) GG genotype were substantially related to COVID-19 severity, which was also associated with comorbidities and some laboratory parameters (p < 0.001). The IL-1β (rs1143634) TT genotype was found to be protective. Likewise, the IL-1β (rs16944) CC genotype was associated with increased mortality. IL-1β rs16944 and IL-6R rs12083537 SNPs are promising potential predictors of SARS-CoV-2 disease severity. Meanwhile, the rs1143634 SNP T allele was protective against severity and mortality risk.

Unemployment and Personal Income Loss After Traumatic Brain Injury

Employment and personal income loss after traumatic brain injury is a major source of postinjury stress and a barrier to societal reintegration. The magnitude of labor market ramifications following traumatic brain injury remains largely unknown. To quantify the 3-year postinjury labor market consequences following traumatic brain injury in Canada. To also estimate the incurred national labor market cost over the study period. This retrospective quasi-experimental, pan-Canadian observational cohort study used linked administrative health and federal taxation data obtained between 2007 and 2017. Mixed-effects difference-in-difference regressions were constructed to estimate the annualized magnitude of the personal income and employment loss during each of the 3 years following injury, respectively, relative to preinjury baseline. Participants included tax-filing adult (19 to 61 years old) traumatic brain injury survivors. Traumatic brain injury. Coprimary outcomes were personal income loss and the proportion of newly unemployed individuals per annum. Secondary objectives were to quantify income and employment loss within mild, moderate, and severe traumatic brain injury subgroups. A total of 18 050 patients with traumatic brain injury between 2007 and 2017 were identified (mean age, 38.0 [SD, 12.4] years; 13 360 male [74.0%]), each of whom was followed up with for 3 consecutive fiscal years. Mean income was CAD $42 600 (US $31 083) in the fiscal year prior to injury and 82% were employed at time of injury. The adjusted mean loss of personal income was CAD $7635 (US $5650) in the first year after injury (Y+1) and CAD $5000 (US $3700) in the third year after injury (Y+3) relative to uninjured controls. In each of the 3 postinjury years, 7.8% individuals were newly unemployed compared with the preinjury baseline. The adjusted average personal income loss for mild, moderate, and severe traumatic brain injury subgroups were CAD $3354 (US $2482), CAD $6750 (US $4995), and CAD $17 375 (US $12 859), respectively, at Y+3; the proportion of unemployed individuals increased by 5.8%, 9.2%, and 20% across the same groups at Y+3 after injury relative to preinjury baseline. The estimated total reduction in personal income aggregated over the 3 postinjury years for the affected participants was CAD $588 million (US $435 million). This work represents national cohort data quantifying the labor market implications of traumatic brain injury. These results may be used to inform economic evaluations and social service resource allocation.

Expressions of vascular endothelial cadherin and soluble Fas ligand in patients with viral myocarditis and their correlations

Abstract Background We aimed to explore the expressions of vascular endothelial cadherin (VE-cadherin) and soluble Fas ligand (sFasL) in patients suffering from viral myocarditis (VMC), and the correlations between them. Methods Fifty VMC patients diagnosed between January 2022 and December 2023 were selected as the subjects (experimental group), and an equal number of participants receiving health examination were included as a control group. The experimental group was then subdivided into mild, moderate, and severe subgroups according to their clinical symptoms. Peripheral blood samples were collected to detect the serum levels of VE-cadherin and sFasL through enzyme-linked immunosorbent assay, and the differences in their levels were compared. The clinical baseline data and cardiac function indicators (left ventricular systolic function as well as early and late left ventricular diastolic function) were acquired. Results The ejection fraction of the inferior ventricular septum showed no significant difference between the two groups (p&gt;0.05), but there were significant differences in the remaining indicators (p&lt;0.05). The levels of VE-cadherin and sFasL in the experimental group were significantly higher than those in the control group (p&lt;0.05). The severe VMC group had significantly elevated VE-cadherin and sFasL levels compared with those of moderate and mild groups, and the moderate group had significantly raised levels compared to those of the mild group (p&lt;0.05). VE-cadherin level was positively correlated with sFasL level. Conclusions The elevation of serum VE-cadherin and sFasL levels may be associated with myocardial inflammatory response and cardiac function damage. VE-cadherin and sFasL are potential biomarkers of VMC for early diagnosis and treatment evaluation.

Investigation of the diagnostic and prognostic importance of Tumor Necrosis Factor-alfa (TNF-α), Procalcitonin (PCT), Interleukin-6 (IL-6) and Haptoglobin (HP) in calves with neonatal diarrhea

This study aims to investigate the effects of Procalcitonin, Tumor Necrosis Factor-alpha, Interleukin-6, and Haptoglobin levels on the prognosis of calves classified according to the severity of diarrhea. The animal material comprised 48 diarrheic calves of different breeds and sexes, aged 1‐30 days, and 16 healthy calves aged 1–30 days. The 48 diarrheic calves used were divided into 3 groups, each consisting of 16 calves. Group 1 was designed as Viral (Rota + Corona n = 16), Group 2 as Bacterial (E. coli n = 16), and Group 3 as Parasitic (Cryptosporidiosis n = 16). Each of these groups was further divided into 2 subgroups (moderate and severe subgroups). Blood samples were taken from the diarrheic calves before treatment (0 h) and at 24 and 72 h after treatment. Complete blood count, biochemical, blood gas analyses, and ELISA tests were performed.It was determined that 18.75 % (9/48) of the 48 diarrheic calves included in the study died, while 81.25 % (39/48) survived. The highest mortality rate among the patient groups was observed in the severe rota + corona group (37.5 %).The average PCT concentration in the diarrheic calves in the Rota-corona and E. coli groups at 0 and 24 hours was found to be higher than both the healthy calves and the diarrheic calves in the Cryptosporidium spp. group (P<0.001). This increase was also observed in the Cryptosporidium spp. group at 72 h (P<0.001). A positive and moderate correlation was observed between Procalcitonin and TNF-α (r = 0.603, P<0.001). As a result, it was concluded that the Procalcitonin value, along with other tests, could be used as a biomarker to determine the prognosis of the disease in diarrheic calves, regardless of the etiological agent. This study was evaluated as an original study in which cytokines and acute phase proteins were investigated before and after treatment, with diarrhea divided into subgroups.

Blood serum TGF-β1 content in children with new coronavirus infection

Impaired serum TGF-β1 production is one of the proposed mechanisms for coronavirus disease 2019 (COVID-19).Study objective: to study blood serum TGF-β1 content in children with new coronavirus infection.Materials and methods: a one-stage study was conducted in 119 patients with COVID-19 and compared with 118 healthy children of the same age and sex as a control group. The age range in both groups was 11.0 years. Preschoolers (0–6 years old) and schoolchildren (7–17 years old) in the group with COVID-19 were 21 (18%) and 98 (82%), respectively. Children with COVID-19 were divided into asymptomatic (n=23), mild (n=61), and moderate (n=35) subgroups. Serum samples for TGF-β1 concentration analysis were taken from all patients and tested by flow fluorimetry. The data were processed using the IBM SPSS Statistics Version 25.0 software package (International Business Machines Corporation, license No Z125-3301-14, USA).Results: median serum TGF-β1 levels of children 0–17 years old with COVID-19 regardless of the form of severity were significantly higher than in the control group. The serum concentration of TGF-β1 in children with COVID-19 of preschool age was increased comparing to schoolchildren. Children 0-6 years old with a moderate form of coronavirus infection had high serum TGF-β1 values when compared with school-age patients.Conclusion: elevated serum TGF-β1 levels were found in children both without clinical manifestations and with symptoms of coronavirus infection, reaching maximum values in the moderate form in children 0–6 years old.

Association Between Smell Loss, Disease Burden, and Dupilumab Efficacy in Chronic Rhinosinusitis with Nasal Polyps.

To evaluate the association between smell loss and other aspects of disease, and evaluate dupilumab efficacy in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP) and moderate or severe smell loss. This post-hoc analysis of the SINUS-24/52 studies (NCT02912468/NCT02898454) analyzed nasal polyp score (NPS, 0-8), nasal congestion/obstruction (NC, 0-3), Lund-Mackay CT-scan score (LMK-CT, 0-24), rhinosinusitis severity visual analog scale (RS-VAS, 0-10), and 22-item Sinonasal Outcome Test (SNOT-22, 0-110) according to baseline monthly average patient-reported loss of smell scores (LoS, 0-3) of >1 to 2 (moderate) or >2 to 3 (severe) in patients randomized to dupilumab 300 mg or placebo every 2 weeks. Of 724 patients randomized, baseline LoS was severe in 601 (83%) and moderate in 106 (15%). At baseline, severe versus moderate LoS was associated with 1-point greater severity of NC (odds ratio [OR] 6.01 [95% confidence interval, (CI) 3.95, 9.15]), 5-point greater severity of LMK-CT (OR 2.19 [1.69, 2.85]), and 8.9-point greater severity of SNOT-22 (OR 1.35 [1.20, 1.49]). At Week 24, least squares mean differences (95% CI) dupilumab versus placebo in change from baseline were: NPS -1.90 (-2.56, -1.25) and -1.95 (-2.20, -1.70) in the moderate and severe baseline LoS subgroups, respectively; NC -.35 (-.64, -.06) and -1.00 (-1.13, -.87); LMK-CT -6.30 (-7.88, -4.72) and -6.22 (-6.82, -5.63); RS-VAS -1.18 (-2.20, -.16) and -3.47 (-3.90, -3.03); and SNOT-22 -7.52 (-14.55, -.48) and -21.72 (-24.63, -18.82); all nominal P < .05 versus placebo. Improvements with dupilumab in NC, RS-VAS, and SNOT-22 were statistically greater in patients with severe versus moderate baseline LoS. Significant smell impairment in severe CRSwNP is associated with significant disease (NC, RS-VAS, LMK), health-related quality of life impairment (SNOT-22), asthma, and non-steroidal anti-inflammatory drug-exacerbated respiratory disease. Dupilumab significantly improved NPS, NC, LMK-CT, RS-VAS, and SNOT-22 in subjects with moderate and severe baseline smell loss.

Analysis of factors affecting the progression of visual field defects in patients with myopia and primary open-angle glaucoma

Objective: To investigate the factors affecting the progression of visual field defects in patients with myopia and primary open-angle glaucoma (POAG), and to clarify whether the factors vary in patients with different degrees of myopia. Method: An ambispective cohort study was conducted among patients diagnosed with myopia and POAG from the glaucoma outpatient department at the Zhongshan Ophthalmic Center of Sun Yat-sen University between January 2006 and January 2024. Based on the criteria of functional visual field progression, patients were divided into the progression group and non-progression group, and further divided into the low to moderate myopia subgroup and high myopia subgroup according to the degree of myopia. The patient age, gender, type of glaucoma (high tension glaucoma and normal tension glaucoma), spherical equivalent refraction, best corrected visual acuity (BCVA, recorded as the logarithm of the minimum angle of resolution), intraocular pressure (IOP), central corneal thickness, baseline visual field, history of ophthalmic surgery (corneal refractive surgery and glaucoma surgery), and number of anti-glaucoma medications were summarized. The generalized estimation equation was used for comparison between groups, and the Cox proportional hazards model was used to analyze the factors affecting the progression of visual field defects. Results: A total of 182 eyes from 106 patients were included in this study. There were 57 eyes in the progression group and 125 eyes in the non-progression group. Compared with the non-progression group, the progression group had the older age [43 (29, 53) years old], worse BCVA [0.05 (0.00, 0.17)], greater IOP fluctuation [1.8 (1.3, 2.9)mmHg(1 mmHg=0.133 kPa)], more common baseline central defects [52.6%(30/57)], higher visual field pattern standard deviations [8.92 (5.32, 12.00)dB], lower visual field index [77% (67%, 88%)], and more anti-glaucoma medications [35.1% (20/57) patients used three medications] (all P<0.05). The Cox proportional hazards models showed that the baseline moderate visual field defects [hazard ratio (HR)=2.33, 95% confidence interval (CI): 1.25 to 4.36, P=0.008], baseline central defects (HR=2.09, 95%CI: 1.11 to 3.93, P=0.022), older age (Model A, HR=1.03, 95%CI: 1.00 to 1.05, P=0.017; Model B, HR=1.02, 95%CI: 1.00 to 1.05, P=0.019), and greater IOP fluctuation (Model A, HR=1.54, 95%CI: 1.32 to 1.81, P<0.001; Model B, HR=1.49, 95%CI: 1.26 to 1.75, P<0.001) were risk factors for visual field progression. In the low to moderate myopia subgroup, the increased risk of progression was associated with baseline central defects (HR=5.74, 95%CI: 1.72 to 19.20, P=0.005), worse BCVA (Model A, HR=15.80, 95%CI: 2.07 to 121.00, P=0.008; Model B, HR=12.50, 95%CI: 2.65 to 58.70, P=0.001), and older age (Model A, HR=1.05, 95%CI: 1.02 to 1.08, P=0.002; Model B, HR=1.07, 95%CI: 1.03 to 1.11, P<0.001). In the high myopia subgroup, the increased risk of progression was associated with baseline moderate visual field defects (HR=2.35, 95%CI: 1.12 to 4.92, P=0.024) and greater IOP fluctuation (Model A, HR=1.50, 95%CI: 1.24 to 1.82, P<0.001; Model B, HR=1.52, 95%CI: 1.26 to 1.83, P<0.001). Conclusions: Age, IOP fluctuation, baseline moderate visual field defects, and baseline central defects were the factors affecting the progression of visual field defects in patients with myopia and POAG. There were differences in the influencing factors of visual field progression in patients with different degrees of myopia.

Effect of frailty on effectiveness and safety of GLP-1 receptor agonists versus SGLT2 inhibitors in people with type 2 diabetes in Taiwan: a retrospective, nationwide, longitudinal study

GLP-1 receptor agonists and SGLT2 inhibitors are increasingly being used in people with type 2diabetes on the basis of findings from randomised clinical trials; however, little is known of whether clinical outcomes are affected by frailty in real-world settings. We aimed to compare the clinical effectiveness and safety of GLP-1 receptor agonists and SGLT2 inhibitors in managing type 2diabetes, with a specific focus on stratifying people by their frailty status. In this retrospective, nationwide, longitudinal study, we identified people (aged ≥20years) with type 2 diabeteswho newly initiated either a GLP-1 receptor agonist or an SGLT2 inhibitor during the period Jan 1, 2017to Dec 31, 2019 from the Taiwan National Health Insurance database. Individuals were excluded if they had been diagnosed with cancer, received dialysis for kidney failure, or had prescriptions for a GLP-1 receptor agonist or an SGLT2 inhibitor, within 1year before the index date. Mortality data were collected from the Taiwan National DeathRegistry. Eligible individuals were categorised into three frailty subgroups-fit, mild frailty, and moderate or severe frailty-on the basis of the multimorbidity frailty index. Propensity score matching (1:1) was used to balance covariates between recipients of GLP-1 receptor agonists and SGLT2 inhibitors among each frailty subgroup. Clinical outcomes of interest included three-point major adverse cardiovascular events (non-fatal acute myocardial infarction, non-fatal stroke, and fatal cardiovascular disease), all-cause mortality, hospitalisation for heart failure, dialysis or renal transplant, severe diabetic foot complications, retinopathy, hospitalisation for severe hyperglycaemia, and hospitalisation for severe hypoglycaemia. The association between the use of a GLP-1 receptor agonist versus an SGLT2 inhibitor and the risk of the outcomes of interest among each frailty subgroup was examined using a subdistribution hazard model. We identified 320 210people with type 2diabetes, of whom 280 163 met the eligibility criteria, who initiated either a GLP-1 receptor agonist (n=22 968; mean age 57·7years [SD 13·9], 11 338 [49·4%] were female, and 11 630 [50·6%] were male) or SGLT2 inhibitor (n=257 195; mean age 58·8years [12·3], 107 988 [42·0%] were female, and 149 207 [58·0%] were male) during 2017-19. After matching, 11 882, 7210, and 3414pairs of GLP-1 receptor agonist and SGLT2 inhibitor users were assigned in the fit, mild frailty, and moderate or severe frailty subgroups. All clinical outcomes were comparable between users of GLP-1 receptor agonists and SGLT2 inhibitors among each frailty subgroup, except fora higher risk of hospitalisation for severe hyperglycaemia with GLP-1 receptor agonists than withSGLT2 inhibitors in the mild frailty subgroup (subdistribution hazard ratio 1·25 [95% CI 1·13-1·38]; p<0·0001) and a higher risk of dialysis or renal transplant with GLP-1 receptor agonists than with SGLT2 inhibitors in the fit (2·43 [1·82-3·23]; p<0·0001), mild frailty (3·93 [3·03-5·09]; p<0·0001), and moderate or severe frailty (2·60 [2·03-3·31]; p<0·0001) subgroups. Formulating clear and updated guidelines on the use of GLP-1 receptor agonists and SGLT2 inhibitors according to frailty status could improve management of type 2diabetes.

Factors Affecting Lateral Overgrowth in Operatively Treated Lateral Condyle Fractures in Children.

The most frequent sequelae of pediatric lateral condyle fractures is lateral condyle overgrowth (LCO). The purpose of our study was to investigate LCO in relation to age, quality of reduction, type of fixation, and fracture displacement. We retrospectively analyzed operatively treated lateral condyle fractures in children. The percent change in interepicondylar width (IEW) ((final - initial)/ initial x 100) was used to quantify LCO. IEW was measured from the medial and lateral epicondyles of the distal humerus, using the AP radiographs taken at admission (initial) and follow-up visits (final). The Song classification was used to classify fractures. Fixation was classified as pins, screws or both. The quality of reduction was defined as anatomic or nonanatomic (>2mm of displacement). Patients were stratified into mild (0% to 10% overgrowth), moderate (10% to 20% overgrowth), and severe (>20% overgrowth) subgroups for further analysis. Two hundred one patients were included in the study with an average time between initial and final radiograph measurements of 11.32 weeks. There was an average 11.84 %LCO. Using multivariable analysis, three variables demonstrated significant, independent associations with %LCO: age, race, and quality of reduction. Increasing age remained inversely associated with %LCO. Compared with White patients, Black and Asian patients had significantly greater %LCO. Patients with nonanatomic reductions had a significantly greater %LCO compared with anatomic reductions. When patients were stratified into mild, moderate, and severe groups, age in the mild group, nonanatomic reduction in the moderate group, and race in the severe group were found to be independently associated with increased %LCO using multivariable analysis. The amount of LCO was found to be related to nonanatomic reduction, younger age, and Black and Asian race. Interestingly, it was not related to the amount of initial displacement or type of hardware used. To date, this is the largest study investigating LCO in surgically treated lateral condyle fractures. Level III-retrospective cohort study.

Effect of Lens Deviation on Peripheral Defocus and Optic Quality in Adolescents With Moderate and Severe Myopia.

The aim of this study was to analyze the effects of lens deviation on peripheral defocus and optic quality in adolescents with moderate and severe myopia. This prospective study enrolled 81 children (81 eyes). The spherical equivalent was -5.0≤SE≤-6.0 diopter. The participants were divided into two subgroups based on their eccentricity (inferior temporal) after wearing the lenses for 12 months. Between them, the low eccentric subgroup (A) had a total eccentric distance of less than 0.5 mm, and the moderate and severe eccentric subgroup (B) had a total eccentric distance of ≥0.5 mm. Peripheral defocus and eccentricity were measured before and after wearing the lenses, and the Spearman test was used to compare the parameters. Parameters such as the total peripheral defocus (TRDV) were significantly lower in subgroup B than in subgroup A after 12 months of orthokeratology lens usage. The axial length growth (ΔAL) in subgroup A was higher than that in subgroup B. Axial length growth, TRDV, and other parameters were significantly associated with eccentricity. The modulation transfer function cutoff and Strehl ratio were also significantly associated with eccentricity. Greater eccentricity within a certain range can induce greater periretinal defocus and improve the ΔAL.

Symptom burden and quality of life among patient and family caregiver dyads in advanced cancer.

Symptom management among patients diagnosed with advanced cancer is a high priority in clinical care that often involves the support of a family caregiver. However, limited studies have examined parallel patient and caregiver symptom burden and associations with their own and each other's quality of life (QOL). This study seeks to identify patient and caregiver symptom clusters and investigate associations between identified clusters and demographic, clinical, and psychosocial factors (cognitive appraisals and QOL). This study was a secondary analysis of self-reported baseline survey data collected from a randomized clinical trial of 484 adult advanced cancer patients and their caregivers. Latent class analysis and factor analysis were used to identify symptom clusters. Bivariate statistics tested associations between symptom clusters and demographic, clinical, and psychosocial variables. The most prevalent symptom for patients was energy loss/fatigue and for caregivers, mental distress. Low, moderate, and high symptom burden subgroups were identified at the patient, caregiver, and dyad level. Age, gender, race, income, chronic conditions, cancer type, and treatment type were associated with symptom burden subgroups. Higher symptom burden was associated with more negative appraisals of the cancer and caregiving experience, and poorer QOL (physical, social, emotional, functional, and overall QOL). Dyads whose caregivers had more chronic conditions were more likely to be in the high symptom burden subgroup. Patient and caregiver symptom burden influence their own and each other's QOL. These findings reinforce the need to approach symptom management from a dyadic perspective.

The relationship between serum transglutaminase-2 levels and the severity of chronic spontaneous urticaria

Chronic spontaneous urticaria (CSU) is an immunological disease that is depicted by high prevalence and eminent burden for patients and society that is attributable to the arbitrary nature of symptoms and inconsistent tools for assessment of activity and severity. Transglutaminase-2 (TG2) is a posttranslational enzyme that is pervasively expressed in many cells and tissue types including mast cells. It has various biological functions, and its role in allergic disorders has been highlighted and delineated through several postulated mechanisms. This case–control study aimed at determining the relationship between serum levels TG2 and severity of CSU. To the best of our knowledge, this is the first study in Egypt to determine the relationship between serum TG2 and severity of CSU. We enrolled 60 adult patients with confirmed diagnosis of CSU. According to urticaria activity score (UAS), patients were categorized into three groups [20 with mild disease; UAS = 0, 20 with moderate disease; UAS = 1–3, 20 with severe disease; UAS = 4–6]. Another 20 healthy individuals (age and gender matched) served as a control group. All patients were subjected to detailed medical history, clinical examination, complete blood count with differential, serum total IgE, CRP, ESR, TSH, ANA, liver and renal function tests. Serum level of TG2 was done by quantitative ELISA for all enrolled patients and controls. Serum TG2 is significantly higher in patients group compared to control group (P value < 0.001). Serum TG2 levels were significantly higher in patients with severe disease compared to patients with moderate or mild disease. This is illustrated by the significant positive correlation between serum TG2 and UAS (r 0.814 and P value 0.000). Moreover, serum TG2 accurately classified CSU patients into mild, moderate and severe subgroups: as regards differentiation between mild and moderate cases (sensitivity 70%, specificity 80%, PPV 77.8, NPV 72.7) and as for the differentiation between moderate and severe cases (sensitivity 95%, specificity 90%, PPV 90.5, NPV 94.7).

Usefulness of bioelectrical impedance analysis in multiple sclerosis patients-the interrelationship to the body mass index.

Patients with multiple sclerosis (MS) have many potential factors (disease duration, spasticity, immobilization, or glucocorticoid use) that can deteriorate their nutritional status and impact both the progression and prognosis of the disease. Body mass index (BMI), the most widely used nutritional status assessment tool, has important limitations because it does not provide any data on body composition. This study aimed to assess the interrelationship between nutritional status assessment by both body mass index (BMI) and body composition using bioelectrical impedance analysis (BIA) and the consistency of diagnosis for underweight/underfat, normal weight/healthy, overweight/overfat, and obesity/obese MS patients. Anthropometric [BMI and waist-to-height ratio (WHtR)] and body composition (BIA) data were evaluated in 176 patients with MS. Patients were categorized into four nutritional status subgroups (underweight, normal weight, overweight, obese according to BMI, and underfat, healthy, overfat, and obese according to fat mass% by BIA). The median Expanded Disability Status Scale score was 4.5. Patients were then divided according to EDSS score as mild (EDSS 1.0-4.0) or moderate (EDSS 4.5-6.5) disability subgroups. Based on BIA assessment, there was a significantly higher prevalence of overfat than of overweight based on BMI [n = 50 (28.41%) vs. n = 38 (21.59%); p < 0.05]. However, the prevalence of obesity did not differ significantly regardless of the mode of diagnosis and was not significantly lower when assessed using BIA [n = 26 (14.77%) vs. n = 30 (17.05%), respectively]. The overall compatibility rates (CR) of diagnoses made using both BMI and BIA were 75.6, 77.0, and 70.1% for all patients with MS and the mild and moderate subgroups, respectively. The lowest CR was observed in the overweight group. Adiposity significantly underestimated BMI in all subgroups. In the moderate MS subgroup, BMI significantly overcategorized patients with MS as having a normal weight (p < 0.05). Stratification for abdominal obesity (WHtR > 0.5) showed that BMI significantly underestimated the prevalence of MS in overweight and obese vs. overfat and obese patients, as assessed using BIA (60.5 vs. 67%; p < 0.05). Clinical status (EDSS and ΔEDSS) was more closely related to the nutritional status categorized by FAT% assessed using BIA than using BMI cutoff points. However, the relationship was not statistically significant. Using the BMI cutoff point for nutritional status assessment in patients with MS is associated with a significant underestimation of excess fat mass. BIA-based FAT% based on BIA have a better relationship with abdominal obesity and disability status than with BMI in patients with MS. The highest rate of false-negative diagnoses was based on the BMI in patients with MS and moderate disability. Adiposity assessment using BIA appears to be a useful method for proper nutritional status assessment in the patients group.

Left Atrial Phasic Function Impairment in Subacute and Chronic Pulmonary Embolism Patients With Different Degrees of Obstruction: An MRI Feature Tracking Study

BackgroundThe alteration of left atrial (LA) phasic function in subacute and chronic pulmonary embolism (PE) patients is unclear.PurposeTo investigate LA phasic strain and LA‐right ventricular (RV) interaction in subacute and chronic PE patients with different degrees of obstruction by MRI‐feature tracking (MRI‐FT).Study TypeRetrospective.PopulationOne hundred three PE patients (54 subacute [2 weeks to 3 months after initial symptoms], 49 chronic [&gt;3 months after initial symptoms]) and 80 controls.Field Strength/Sequence3.0 T/balanced steady state free precession sequence.AssessmentPatients were divided into mild (pulmonary artery obstruction index [PAOI] &lt; 30%, N = 57), moderate (30% ≤ PAOI &lt; 50%, N = 27), and severe (50% ≥ PAOI, N = 19) PE subgroups. LA reservoir, conduit, and active pump longitudinal strains (εs, εe, and εa) and strain rates (SRs, SRe, and SRa) and biventricular global strains were measured. Determinants of LA strains were investigated.Statistical TestsANOVA, t‐tests, Mann–Whitney U tests, linear regression. P &lt; 0.05 was considered statistically significant.ResultsFor both subacute and chronic PE patients, LA reservoir, conduit, and active pump strains and strain rates were significantly lower than in controls. However, there were no significant differences in LA strains between patients with subacute and chronic PE (P = 0.933, 0.625, and 0.630 for εs, εe, and εa). The severe PE subgroup had significantly higher εa and SRa than the mild and moderate PE subgroups. LA strains were significantly correlated with RV diameter and biventricular strains, and RV diameter (β = −6.836, −4.084, and −1.899 for εs, εe, and εa) was independently associated with LA strains after adjustment for other factors (R2 = 0.627, 0.536, and 0.437 for εs, εe, and εa).Data ConclusionLA phasic function evaluated by MRI‐FT was significantly impaired in subacute and chronic PE patients, and LA active pump function in the severe PE subgroup was higher than that in the mild and moderate PE subgroups. The independent association between RV diameter and LA strains demonstrates that RV diameter may be an important indicator for monitoring LA dysfunction in PE patients.Evidence Level3Technical EfficacyStage 3

Cluster analysis of social isolation in gynecologic cancer patients: A cross-sectional survey.

To identify the distinct clusters of social isolation among gynecologic cancer patients and analyze the predictive factors associated with each cluster. A total of 463 patients diagnosed with gynecologic cancer were recruited from three tertiary hospitals between November 2021 and March 2023. Using a two-step cluster analysis, participants were categorized into clusters based on social isolation scales. Multinomial logistic regression was then employed to predict factors influencing the identified clusters. Social isolation in gynecologic cancer patients manifested in four distinct clusters: mild social isolation subgroup (13.8%), moderate social isolation subgroup (32.0%), severe isolation subgroup (33.5%), and high social isolation (20.70%). Multivariate logistic regression analysis revealed that cognitive emotional regulation, social support, negative emotions, endometrial cancer, and disease recurrence or metastasis were significant predictive factors for the identified social isolation clusters (P < 0.05). The study underscored the heterogeneity in the social isolation characteristics of gynecologic cancer patients. Consequently, healthcare professionals should prioritize the identification of potential high-risk groups and devise personalized interventions to prevent and mitigate the occurrence of social isolation.

Difference in discrepancies of mandibular incisor compensation relative to Menton deviation between Class III roll- and yaw-dominant asymmetries.

To compare mandibular incisor compensation relative to Menton (Me) deviation between skeletal Class III patients with roll- and yaw-dominant mandibular asymmetries. Sixty skeletal Class III patients (21.62 ± 2.69 years) with facial asymmetry were divided into roll- or yaw-dominant asymmetry groups. Mandibular skeletal and incisor measurements were carried out using cone-beam computed tomography data, and values were compared between the two asymmetry groups or between moderate and severe asymmetry subgroups using independent t-test or Mann-Whitney U-test. The relationship between skeletal and dental measurements was assessed using Pearson correlation coefficient. Relative to the mandibular midsagittal plane, the yaw-dominant group presented significantly greater mandibular dental midline deviation in distance (LI-mid deviation, 2.15 mm) and angulation (4.20°) toward the nondeviated side than the roll-dominant group (P < .001). The ratio of amount of LI-mid deviation to Me deviation was significantly greater in the yaw-dominant group (26.44%) than in the roll-dominant group (1.76%; P < .001). In the yaw-dominant group, the LI-mid deviation was significantly greater in the severe asymmetry subgroup than in the moderate asymmetry subgroup, and the amount of mandibular incisor compensation was positively correlated with Me deviation and mandibular yaw. Mandibular incisor compensation differed significantly between the roll- and yaw-dominant asymmetry groups. The yaw-dominant group demonstrated significant mandibular dental midline deviation, and dental compensation of the anterior teeth was positively correlated with Me deviation and mandibular yaw.

High prevalence of exon-13 variants in USH2A-related retinal dystrophies in Taiwanese population

BackgroundBiallelic pathogenic variants in USH2A lead to Usher syndrome or non-syndromic retinitis pigmentosa, and shown to have geographical and ethnical distribution in previous studies. This study provided a deeper understanding of the detailed clinical features using multimodal imaging, genetic spectrum, and genotype–phenotype correlations of USH2A-related retinal dystrophies in Taiwan.ResultsIn our cohort, the mean age at first visit was 47.66 ± 13.54 years, and the mean age at symptom onset, which was referred to the onset of nyctalopia and/or visual field constriction, was 31.21 ± 15.24 years. Among the variants identified, 23 (50%) were missense, 10 (22%) were splicing variants, 8 (17%) were nonsense, and 5 (11%) were frameshift mutations. The most predominant variant was c.2802T>G, which accounted for 21% of patients, and was located in exon 13. Patients with truncated alleles had significantly earlier symptom onset and seemly poorer disease progression regarding visual acuity, ellipsoid zone line length, and hypofluorescent lesions in the macula than those who had the complete gene. However, the clinical presentation revealed similar progression between patients with and without the c.2802T>G variant. During long-term follow-up, the patients had different ellipsoid zone line progression rates and were almost evenly distributed in the fast, moderate, and slow progression subgroups. Although a younger onset age and a smaller baseline intact macular area was observed in the fast progression subgroup, the results showed no significant difference.ConclusionsThis is the first cohort study to provide detailed genetic and longitudinal clinical analyses of patients with USH2A-related retinal dystrophies in Taiwan. The mutated allele frequency in exon 13 was high in Taiwan due to the predominant c.2802T>G variant. Moreover, truncated variants greatly impacted disease progression and determined the length of therapeutic windows. These findings provide insight into the characteristics of candidates for future gene therapies.
