Vascular dilatation and congestion and collagen fibre deposition were present. A statistically significant difference was seen in all parameters when caffeine and antioxidants were given against cadmium-induced testicular injury. Overall, we conclude that both caffeine and antioxidants have the ability to reverse cadmium-induced testicular injury when given as pre-treatment prior to cadmium exposure.

Chronic right ventricular (RV) pacing is associated with an increased incidence of heart failure and mortality. Left bundle branch (LBB) pacing could produce near-physiological electrical activation and mechanical synchrony. We aimed to report the effects of upgrading to LBB pacing in heart failure patients after chronic RV pacing.

The indications included pacing-induced cardiomyopathy (PICM) in Group 1 and heart failure after RV pacing with left ventricular ejection fraction (LVEF) ≥ 50% in Group 2. LBB pacing was achieved by penetrating the pacing lead to the subendocardium of left-sided interventricular septum through the venous access. Left ventricular activation time (LVAT) was measured from the pacing stimulus to the ascending peak of lead V5 or V6. All patients underwent clinical and echocardiographic evaluations before and after upgrading.

Totally 27 patients (13 in Group 1 and 14 in Group 2) were consecutively enrolled. The mean follow-up time after upgrade was 10.4 ± 6.1 months. Paced QRS duration was significantly shortened from 174.1 ± 15.8milliseconds to 116.6 ± 11.7milliseconds (p<.0001). The mean LVAT was 83.2 ± 11.7milliseconds. LVEF increased from 40.3 ± 5.2% before upgrading to 48.1 ± 9.5% at follow-up in patients with PICM. GW4869 Serum N-terminal probrain natriuretic peptide levels decreased and New York Heart Association classification improved in both groups. No upgrade-related complications were observed.

Upgrading to LBB pacing was feasible and effective with improved cardiac function in heart failure patients with both reduced and preserved LVEF after RV pacing.

Previous research suggests that institutionalization can disrupt emotion regulation processes, which contribute to internalizing symptoms. However, no prior work has investigated how early orphanage care shapes emotion regulation strategy usage (e.g., cognitive reappraisal, expressive suppression) and whether the said strategy usage contributes to internalizing symptoms. This study probed emotion regulation strategy usage and internalizing symptoms in a sample of 36 previously institutionalized and 58 comparison youth. As hypothesized, previously institutionalized youth exhibited higher rates of internalizing symptoms than comparison youth, and more frequent use of suppression partially accounted for the relationship between early institutional care and elevated internalizing symptoms. Contrary to our initial hypotheses, reappraisal use did not buffer previously institutionalized or comparison youth against internalizing symptoms. Our findings highlight the potential utility of targeting emotion regulation strategy usage in adversity-exposed youth in future intervention work.

Antenatal corticosteroids (ACSs) administered to women before preterm birth improve neonatal health. Proportionately more women are obese or overweight in current obstetric populations than those who were included in the original trials of ACSs, and it remains uncertain if higher doses are required for such women.

Our aim was to assess the association between maternal body mass index (BMI) and infant morbidity after the administration of ACSs.

In the secondary analysis of the ASTEROID trial cohort, women at risk of preterm birth at <34weeks' gestation were randomised to betamethasone or dexamethasone. Infant outcomes were compared according to whether women were of normal weight (BMI<25kg/m

), overweight (BMI 25-29.9kg/m

) or obese (BMI≥30kg/m

).

Of 982 women with a singleton pregnancy and BMI data, 519 (52.9%) were of normal size, 241 (24.5%) were overweight and 222 (22.6%) were obese. Compared with infants born to women of normal weight, there was little or no difference in respiratory distress syndrome in infants born to women who were overweight (odds ratio (OR)=0.92, 95% confidence interval (CI) 0.57, 1.49) or obese (OR=1.44, 95% CI 0.90, 2.31). Similarly, there were no significant differences between infants born to women in the three BMI groups for other morbidities, including bronchopulmonary dysplasia, mechanical ventilation, intraventricular haemorrhage, retinopathy of prematurity, patent ductus arteriosus, necrotising enterocolitis, perinatal death or combined serious morbidity.

Maternal body size is not associated with infant morbidity after ACS exposure. Dose adjustment for women with higher BMI is not required.

Recent studies reveal that extracellular vesicles such as exosomes present a potential mechanism for propagation of pathological α-synuclein throughout the brain. The ability of exosomes to transport proteins and genetic material between cells, including mRNA and microRNAs which have been implicated in PD pathology, provides critical insights as to how exosomes may contribute to pathological progression in PD. Advances have also been made in the investigation of exosomes as potential tools for the modulation of Parkinson's pathology; their detection extracellularly may facilitate their use as biomarkers, while their small size could be utilised as vectors for the delivery of therapeutics. The aim of this review was to highlight our current knowledge of the role of exosomes in PD and potential clinical application.
