A Longitudinal Study Of Perinatal Depression and The Risk Role Of Cognitive Fusion and Perceived Stress On Postpartum Depression
Changes in depression were influenced by multiple factors with stability and predictability across time. Psychological dimensions, such as perceived stress and cognitive fusion, are risk factors for developing postpartum depression and antenatal depression.
KEY FINDINGS: Changes in depression were influenced by multiple factors with stability and predictability across time. Psychological dimensions, such as perceived stress and cognitive fusion, are risk factors for developing postpartum depression and antenatal depression.
BACKGROUND: Purpose of this study is to explore fluctuations in perinatal depression based on physiological, psychological and interpersonal dimensions to analyse risk factors across three time points: in the third trimester and at weeks 1 and 6 postpartum. Pregnant women experience depression at multiple time points and require screening. Studies have shown protective and negative factors related to postpartum depression. Cognitive fusion refers to an individual's emotions and behaviours that are regulated and influenced by that individual's own cognitive overregulation, especially when facing stress. This is an important psychological factor related to depression, but little is known about it in pregnant women.
DETAILS: Pregnant women (n = 207) were recruited, and a questionnaire survey was performed at 32-34 weeks of pregnancy and at weeks 1 and 6 postpartum. Repeated-measures analysis of variance was performed to analyse the changes in depression over time. Regression analysis and linear mixed modelling were used to identify risk factors. Pearson's correlation analysis was performed to analyse the relationships between variables. Of the pregnant women, 36.70% experienced antenatal depression and prolonged depression with the onset of postpartum depression (12.21%). Some depressive moods disappeared spontaneously after delivery (47.37%). Perceived stress was the highest risk predictor of postpartum depression (ß = 0.332), followed by cognitive fusion (ß = 0.178), which remained stable over time and might have been positively related to having a vulnerable personality (0.2 < r < 0.4). Social support plays a positive role in lowering postpartum depression (ß = -0.027).

Efficacy and Safety of Time-Restricted Eating in Metabolic Dysfunction-Associated Steatotic Liver Disease
This 16-week RCT compared TRE, CR, and standard of care in patients with MASLD. It effectively reduced steatosis, with similar benefits on weight loss, body composition, and metabolic parameters as CR. TRE is a practical dietary strategy for MASLD and warrants further long-term study. TRE's effectiveness in MASLD remains unclear despite its potential metabolic benefits.
KEY FINDINGS: TRE effectively reduces hepatic steatosis in MASLD, with comparable benefits on weight loss, body composition, and metabolic parameters as CR. This approach may serve as a practical dietary strategy for MASLD management.
BACKGROUND: Time-restricted eating (TRE) may improve weight loss, insulin resistance, and body composition, which are key factors in the pathophysiology of metabolic dysfunction-associated steatotic liver disease (MASLD). However, evidence on the efficacy of TRE in patients with MASLD is limited. This study aimed to evaluate the potential benefits of TRE in patients with overweight or obesity and MASLD.
DETAILS: In this 16-week randomized controlled trial, patients with overweight or obesity and MASLD were randomized into three groups in a 1:1:1 ratio: standard of care (SOC), calorie restriction (CR), and TRE. The primary endpoint was an improvement in hepatic steatosis, measured using MRI-proton density fat fraction. Changes in liver fibrosis, body composition, lipid profiles, glucose homeostasis, and sleep quality were also analyzed. Among the 337 participants randomized, 333 were included in the full analysis set (113 in SOC, 110 in CR, and 110 in TRE). After the 16-week intervention, hepatic steatosis significantly decreased in the TRE group (-25.8%) compared to the SOC group (0.7%, p <0.001), with no significant difference between TRE and CR (-24.7%, p >0.999). The TRE group also showed greater reductions in body weight, waist circumference, and body fat mass compared to the SOC group, while changes were comparable between TRE and CR. Liver stiffness, glucose homeostasis, and sleep quality were similar between the TRE and CR groups. No serious adverse events were reported.

Prenatal PM2.5 Exposure Induces Offspring Hypertension via Nrf2/NLRP3 Pathway
Overall, prenatal fine particulate matter exposure induces excessive inflammation and oxidative stress in paraventricular nucleus microglia through the Nrf2/NLRP3 signaling pathway, resulting in central and peripheral sympathetic overactivation, leading to hypertension and left ventricular hypertrophy.
KEY FINDINGS: Overall, prenatal fine particulate matter exposure induces excessive inflammation and oxidative stress in paraventricular nucleus microglia through the Nrf2/NLRP3 signaling pathway, resulting in central and peripheral sympathetic overactivation, leading to hypertension and left ventricular hypertrophy.
BACKGROUND: Adverse factors during pregnancy can significantly increase the incidence of hypertension in adult offspring. Activation of the sympathetic nervous system is closely associated with the development and progression of hypertension.
DETAILS: Authors established a model of offspring hypertension induced by prenatal fine particulate matter exposure to evaluate the role of the sympathetic nervous system activation. Quantitative immunofluorescence and Western blot analysis were used to assess the levels of activated and inhibitory sympathetic neurons. The effects of the central and peripheral sympathetic nervous systems were evaluated using clonidine and renal sympathetic denervation. In addition, the activation of microglia in the lateral ventricle region and the expression of the Nrf2 (nuclear factor E2-related factor)/ NLRP3 (NLR family pyrin domain-containing 3) signaling pathway were analyzed. The adult offspring showed increased neuronal hyperactivity and sympathetic nervous system activity. Specific inhibition of the central sympathetic nervous system and renal denervation effectively reversed the prenatal fine particulate matter-induced blood pressure elevation in adult offspring. In addition, overactivation of oxidative stress and microglia-mediated inflammation in the paraventricular nucleus was responsible for increased central sympathetic activity in the adult offspring exposed to prenatal fine particulate matter. Furthermore, authors confirmed the critical role of the Nrf2/NLRP3 signaling pathway in oxidative stress and inflammation activation in the paraventricular nucleus of adult offspring.

Association of Family History and Polygenic Risk Score With Longitudinal Prognosis in Parkinson Disease
Having a family history of PD predicts slower progression of cognitive decline and caudate dopaminergic degeneration, and less FOG compared with those without a family history independent of PRS. Taken together, information on family history could be used as a proxy for the clinical heterogeneity of PD.
KEY FINDINGS: Having a family history of PD predicts slower progression of cognitive decline and caudate dopaminergic degeneration, and less FOG compared with those without a family history independent of PRS. Taken together, information on family history could be used as a proxy for the clinical heterogeneity of PD.
BACKGROUND: Evidence suggests that either family history or polygenic risk score (PRS) is associated with developing Parkinson disease (PD). However, little is known about the longitudinal prognosis of PD according to family history and higher PRS.
DETAILS: From the Parkinson's Progression Markers Initiative database, 395 patients with PD who followed up for more than 2 years were grouped into those with family history within first-degree, second-degree, and third-degree relatives (N = 127 [32.2%]) vs those without (N = 268 [67.8%]). The PRS of 386 patients was computed using whole-genome sequencing data. Longitudinal assessment of motor, cognition, and imaging based on dopaminergic degeneration was conducted during the regular follow-up period. Effects of family history, PRS, or both on longitudinal changes of cognition, motor severity, and nigrostriatal degeneration were tested using a linear mixed model. The risk of freezing of gait (FOG) according to family history was assessed using the Kaplan-Meier analysis and Cox regression models. During a median follow-up of 9.1 years, PD with positive family history showed a slower decline of caudate dopamine transporter uptake (ß estimate of family history x time = 0.02, 95% CI = 0.002-0.036, p = 0.027). Family history of PD and higher PRS were independently associated with a slower decline of Montreal Cognitive Assessment (ß estimate of family history x time = 0.12, 95% CI = 0.02-0.22, p = 0.017; ß estimate of PRS x time = 0.09, 95% CI = 0.03-0.16, p = 0.006). In those 364 patients without FOG at baseline, PD with positive family history had a lower risk of FOG (hazard ratio of family history = 0.57, 95% CI = 0.38-0.84, p = 0.005).

Renal Outcomes and Safety of Dipeptidyl Peptidase-4 Inhibitors versus Meglitinides in Advanced CKD with Type 2 Diabetes
Curettage remains optimal for thick, hyperkeratotic SKs, enabling histopathological confirmation. The 532-nm laser, preferred subjectively for convenience, may suit small, non-hyperkeratotic lesions but warrants further validation. Propane-butane cryotherapy offers a cost-effective alternative.
KEY FINDINGS:
- DPP-4 inhibitors offer a safer alternative to meglitinides in T2D patients with Stage 5 CKD with lower severe renal outcomes and hypoglycemia risk.
- Hypoglycemia risk is lower with DPP-4i due to glucose-dependent insulinotropic action.
- DPP-4i are weight neutral, helpful in normal or lower BMI patients.
- Renoprotection mechanisms of DPP-4i may involve GLP-1 dependent pathways and antifibrotic effects but need further study.
- Observational data with residual confounding; randomized trials needed for conclusive evidence.
- Cost and access issues may influence DPP-4i use in some settings.
BACKGROUND: Managing hyperglycemia in type 2 diabetes (T2D) patients with advanced chronic kidney disease (CKD) is complex due to altered drug metabolism and risk of adverse events. Conventional treatments like metformin pose risks due to renal excretion; sulphonylureas and pioglitazone involve metabolites renally cleared raising hypoglycemia and fluid retention risks. Meglitinide repaglinide is preferred in this setting due to hepatic metabolism and flexible dosing. DPP-4 inhibitors (DPP-4i) offer a safer profile with low hypoglycemia risk and weight neutrality, but data on their safety and efficacy in Stage 5 CKD remain scarce.
DETAILS: Hung et al. conducted a nationwide Taiwanese cohort study (2012-2020) comparing renal outcomes in Stage 5 CKD patients with T2D starting either DPP-4i (n=5028) or meglitinides (n=2243). Stage 5 CKD was defined using erythropoiesis-stimulating agent (ESA) use as a surrogate for eGFR <15 mL/min/1.73 m2. Propensity score matching adjusted for confounders. The primary composite outcome included renal replacement therapy (RRT), renal death, and kidney-related hospitalization. DPP-4i use was associated with a 14% lower risk of the primary composite renal outcome vs. meglitinides (HR 0.86; 95% CI 0.81-0.92), mainly through reduced need for RRT. Severe hypoglycemia risk was 41% lower in the DPP-4i group. The findings support the renal safety and possible benefits of DPP-4i over meglitinides in severe CKD. Limitations include observational design, ESA use as CKD surrogate, lack of clinical measurements, and limited generalizability due to homogeneous Taiwanese cohort.

Effects of Emergency Nurses' Life-Sustaining Treatment Withdrawal Knowledge, Role Perception, and Job Stress on Providing End-of-Life Care
Despite the challenging environment of the emergency department, nurses who recognize their important role in the process of life-sustaining treatment withdrawal are more likely to provide high-quality EOL care. The perception of nurses' roles is especially influential on psychological care performance, and alternative approaches may be necessary for spiritual care.
KEY FINDINGS: Despite the challenging environment of the emergency department, nurses who recognize their important role in the process of life-sustaining treatment withdrawal are more likely to provide high-quality EOL care. The perception of nurses' roles is especially influential on psychological care performance, and alternative approaches may be necessary for spiritual care.
BACKGROUND: This study aimed to identify predictors of end-of-life (EOL) care provided by emergency nurses in South Korea.
DETAILS: A cross-sectional survey was conducted using a structured questionnaire. Data were collected using Google Forms between June 21 and 30, 2022. A total of 154 emergency nurses from 10 tertiary hospitals in a metropolitan area were recruited using convenience sampling, and 139 completed surveys were analyzed. Multiple linear regression was employed to examine the effects of nurses' knowledge of life-sustaining treatment withdrawal (knowledge), their perceptions of their role in the withdrawal process (role perception), and job stress on EOL care. The mean scores for knowledge, role perception, job stress, and EOL care were 13.09±1.75 (max 6), 4.18±0.44 (max 5), 3.55±0.32 (max 4), and 2.48±0.40 (max 4), respectively. Among the EOL care subdomains, psychological domain scores were the highest. Multiple linear regression analysis indicated that nurses' role perception significantly predicted EOL care performance, particularly in the psychological (F=3.924, P=0.001) and spiritual (F=2.171, P=0.020) domains.
