Risk factors for in-hospital mortality after emergency colorectal surgery in octogenarians: results of a cohort study from a referral center.

Purpose: The objective of this study was to investigate predictive factors of mortality in emergency colorectal surgery in octogenarian patients.

Methods: It is a retrospective cohort study conducted at a single-institution tertiary referral center. Consecutive patients who underwent emergency colorectal surgery between January 2015 and January 2020 were identified.

Deep Learning on Bone Scintigraphy to Detect Abnormal Cardiac Uptake at Risk of Cardiac Amyloidosis.

Background: Cardiac uptake on technetium-99m whole-body scintigraphy (WBS) is almost pathognomonic of transthyretin cardiac amyloidosis. The rare false positives are often related to light-chain cardiac amyloidosis. However, this scintigraphic feature remains largely unknown, leading to misdiagnosis despite characteristic images.

Aortic dissection-Pulmonary embolism association: A therapeutic dilemma.

Aortic dissection is a rare but serious condition Its association with pulmonary embolism is exceptional and produces a real therapeutic dilemma. We are discussing the case of a 67-year-old male patient who presented with paraplegia with infectious syndrome. The chest X-ray performed to screen for an infectious site led to the suspicion of an aortic aneurysm and the CT angiography showed Stanford type B aortic dissection associated with bilateral proximal pulmonary embolism.

Multicenter study of 37 pediatric patients with SCIWORA or other spinal cord injury without associated bone lesion.

Background: Pure traumatic spinal cord injury (without associated bone lesion) are encountered in pediatric accidentology, the most typical being spinal cord injury without radiological abnormality (SCIWORA). The present study reports a multicenter series of under-18-year-olds admitted for traumatic medullary lesion. The objectives were: (1) to describe the causes of pure spinal cord injuries in children in France and their clinical presentation; (2) to identify any prognostic factors; and (3) to describe their medical management in France.

A case-control study about foetal trauma during caesarean delivery.

Objective: The caesarean section rate is gradually increasing in most countries. The frequency of occurrence of foetal injury per birth is estimated to 1%. The majority of these injuries presents a low functional impact, but remains responsible for a significant neonatal morbidity.

Heart rate variability in the standing position reflects training adaptation in professional soccer players.

Purpose: To show that heart rate variability (HRV) in the standing position better reflects the way in which athletes adapt to training in so-called intermittent sports than the indicator of resting parasympathetic tone usually employed in endurance sports.

Methods: Twenty professional soccer players (intermittent sport) took part in a 5-week training session divided into three successive periods: "Warm-up", "Intensive training" and "Tapering". At the beginning and end of each of the three periods, a stand test was carried out and the heart rate was recorded, beat by beat (Polar Team 2).

Constitutive mosaic aneuploidy is a unique genetic feature widespread in the Leishmania genus.

Using fluorescence in situ hybridization, we determined the ploidy of four species of Leishmania: Leishmania infantum, Leishmania donovani, Leishmania tropica and Leishmania amazonensis. We found that each cell in a strain possesses a combination of mono-, di- and trisomies for all chromosomes; ploidy patterns were different among all strains/species. These results extend those we previously described in Leishmania major, demonstrating that mosaic aneuploidy is a genetic feature widespread to the Leishmania genus.

Active epidemiological surveillance of musculoskeletal disorders in a shoe factory.

Aims: (1) To evaluate an active method of surveillance of musculoskeletal disorders (MSDs). (2) To compare different criteria for deciding whether or not a work situation could be considered at high risk of MSDs in a large, modern shoe factory.

Methods: A total of 253 blue collar workers were interviewed and examined by the same physician in 1996; 191 of them were re-examined in 1997.
