Left atrial strain after maximal exercise in competitive waterpolo players

Abstract Left atrial (LA) function is a determinant of left ventricular (LV) filling. It carries out three main functions: reservoir, conduit, contractile. Aim of this study was to evaluate the role of LA and its deformation properties on LV filling at rest (R) and immediately after a maximal exercise (ME) through the speckle tracking echocardiography. Population enrolled was composed by 23 water polo athletes who performed a ME of six repeats of 100 m freestyle swim sets. At ME peak atrial longitudinal strain was reduced but all strain rate (SR) parameters increased, respectively positive peak SR at reservoir phase, SR negative peak at rapid ventricular filling (SRep) and SR negative peak at late ventricular filling (SRlp), that corresponds to atrial contraction phase. We showed a parallel increase in E and A pulsed Doppler wave and SRep and SRlp; particularly at ME, A wave and SRlp increased more respectively than E wave and SRep. SRlp was related to ejection fraction (EF) (r = −0.47; p

Corneal cross ‐linking should be considered as treatment option in Friesian horses with infectious keratitis and corneal dystrophy. Optical coherence tomography, giving information of corneal structure, can help for diagnosis and monitoring.

Conclusion: Cutaneous manifestations in hemodialysis patients were frequent and dominated by xerosis, pruritus, and alopecia. Factors associated with some of these dermatologic manifestations were seniority in hemodialysis, long duration of the hemodialysis session, and female gender. PMID: 32099542 [PubMed]

ConclusionThis is the first ever study reporting the changes in cerebral metabolic activity and multi ‐frame static brain18F FDG PET imaging after L2 DRG stimulation for discogenic low back pain. Predominantly an increased metabolic activity in nociceptive brain matrices are seen with an increased in F18F FDG uptake following L2 DRG stimulation.

ABSTRACT Purpose: To review the outcomes of frontalis suspension surgeries with the use of polytetrafluoroethylene in patients with blepharoptosis. Methods: A retrospective observational study analyzed the outcomes of frontalis suspension surgeries performed in a single institution from 2003 to 2018. All procedures were performed with closed incision and single pentagon techniques. Outcomes were classified as satisfactory or unsatisfactory, with satisfactory defined as a margin reflex distance of>3 mm and3mm e

Conclusions: BVH patients with higher PR values (nonsynchronized saccades) were more prone to oscillopsia independent of their gain values. We suggest that the PR score can be considered a useful measurement of compensation.

We thank Dr Reiffel for his interest in our case description1 and his comments. Indeed, the presence of precordial T-wave inversions in the setting of pulmonary embolism has been described periodically in the literature. The cases described by Dr Reiffel supplement the cases we referenced in our report to reinforce this point. Two theories are often cited as an explanation for this finding. The first is heightened sympathetic tone caused by an autonomic nervous system –mediated response triggered by acute pulmonary embolism.

The DMPK and ZNF9/CNBP genes which mutations are responsible for DM1 and DM2 respectively. DM are multisystemic disorders with brain affection and cognitive deficits. Brain lesions consisting of neurofibrillary tangles are often observed in DM1 and DM2 brain. Neurofibrillary tangles ...
