Does dehydration alter the success rate and technique of three-point shooting in elite basketball?

In order to better inform the effects of dehydration and hydration guidelines, we tested the acute effects of a 2% dehydration protocol on performance and technique of 3-point shooting (3PS) in Elite Basketball players (n = 9). The 3PS technique was monitored by using nanotechnology inertial measurement units positioned onto body joints during the exercise. When dehydrated (−2.1% ± 0.5% of body mass), 7 players experienced a slight decrease (−10.0% ± 19.6%, p = 0.16) in success rate, while RPE increased from 9.1 ± 2.6 to 13.0 ± 2.5 in euhydrated (EUH) and dehydrated (DEH) condition respectively (p = 0.003). DEH slightly altered the 3PS technique as the knee angle increased (p = 0.02) at toe-off time and the hip angle decreased during the 3PS (p = 0.01). The speed of ball release tended to be increased (p = 0.05) in DEH compared to EUH. Data from this study suggest that a 2% dehydration is tolerable for elite Basketball players, although a stronger dehydration might accentuate the effects observed

Ileo-caecal actinomycosis: Report of a case simulating complicated inflammatory bowel disease

peer reviewedAbdominal actinomycosis is a rare infectious disease caused by Actinomyces israelii, a gram-positive anaerobic saprophyte germ that is a normal inhabitant of the upper intestinal tract in humans. Actinomyces israelii rarely cause abdominal infections or actinomycosis. Abdominal actinomysosis is characterised by fistulae and abscesses and may mimic cancer or inflammatory bowel disease. Abdominal actinomycosis is difficult to diagnose preoperatively, and often require surgical removal of the diseased tissue, allowing pathologists for giving the definitive diagnosis, revealed by characteristic "sulfur granules". The authors report herein the case of a 47-year-old man who presented with diarrhoea and abdominal pain. Abdominal computed tomography evoked complicated inflammatory bowel disease and surgical procedure was decided. Laparoscopic exploration did not provide further significant information, and laparotomy with diseased bowel resection was performed. Pathology demonstrated "sulfur granules" and allowed the diagnosis of abdominal actinomycosis. This case demonstrated that abdominal actinomycosis should be included in the differential diagnosis when computed tomography shows an infiltrative and inflammatory mass

Effect of dehydration on performance and technique of three-point shooting in Elite Basketball.

Basketball play is classically accompanied with a significant loss of body water with a potential negative impact on both physical and cognitive performance 1. Very few studies have examined the impact of dehydration on biomechanical adjustments required to score in basketball, though joints angles, the position of the centre of mass and ball release parameters (i.e. height, release speed and angle) are among the best predictive factors of success in basketball shooting 2. Dehydration might alter the biomechanical requirements of successful shots and especially three-point shots (3PS) which generate 16% of points scored during a match. However, only 35% of 3PS are successful in game. Within this framework we analysed the effects of a controlled dehydration protocol on the success and technique of 3PS in elite basketball players. Changes in shooting technique were analysed through changes in body kinematics (i.e. 3D angles of the ankle, knee, hip, shoulder, elbow and wrist, and the height of the centre of mass) and ball release parameters (i.e. height, velocity and angle of the ball at release) of 3PS in a dynamic playing condition

Consensus on circulatory shock and hemodynamic monitoring. Task force of the European Society of Intensive Care Medicine.

OBJECTIVE: Circulatory shock is a life-threatening syndrome resulting in multiorgan failure and a high mortality rate. The aim of this consensus is to provide support to the bedside clinician regarding the diagnosis, management and monitoring of shock. METHODS: The European Society of Intensive Care Medicine invited 12 experts to form a Task Force to update a previous consensus (Antonelli et al.: Intensive Care Med 33:575-590, 2007). The same five questions addressed in the earlier consensus were used as the outline for the literature search and review, with the aim of the Task Force to produce statements based on the available literature and evidence. These questions were: (1) What are the epidemiologic and pathophysiologic features of shock in the intensive care unit ? (2) Should we monitor preload and fluid responsiveness in shock ? (3) How and when should we monitor stroke volume or cardiac output in shock ? (4) What markers of the regional and microcirculation can be monitored, and how can cellular function be assessed in shock ? (5) What is the evidence for using hemodynamic monitoring to direct therapy in shock ? Four types of statements were used: definition, recommendation, best practice and statement of fact. RESULTS: Forty-four statements were made. The main new statements include: (1) statements on individualizing blood pressure targets; (2) statements on the assessment and prediction of fluid responsiveness; (3) statements on the use of echocardiography and hemodynamic monitoring. CONCLUSIONS: This consensus provides 44 statements that can be used at the bedside to diagnose, treat and monitor patients with shock

Mutations in ZMYND10, a Gene Essential for Proper Axonemal Assembly of Inner and Outer Dynein Arms in Humans and Flies, Cause Primary Ciliary Dyskinesia

Primary ciliary dyskinesia (PCD) is a ciliopathy characterized by airway disease, infertility, and laterality defects, often caused by dual loss of the inner dynein arms (IDAs) and outer dynein arms (ODAs), which power cilia and flagella beating. Using whole-exome and candidate-gene Sanger resequencing in PCD-affected families afflicted with combined IDA and ODA defects, we found that 6/38 (16%) carried biallelic mutations in the conserved zinc-finger gene BLU (ZMYND10). ZMYND10 mutations conferred dynein-arm loss seen at the ultrastructural and immunofluorescence level and complete cilia immotility, except in hypomorphic p.Val16Gly (c.47T>G) homozygote individuals, whose cilia retained a stiff and slowed beat. In mice, Zmynd10 mRNA is restricted to regions containing motile cilia. In a Drosophila model of PCD, Zmynd10 is exclusively expressed in cells with motile cilia: chordotonal sensory neurons and sperm. In these cells, P-element-mediated gene silencing caused IDA and ODA defects, proprioception deficits, and sterility due to immotile sperm. Drosophila Zmynd10 with an equivalent c.47T>G (p.Val16Gly) missense change rescued mutant male sterility less than the wild-type did. Tagged Drosophila ZMYND10 is localized primarily to the cytoplasm, and human ZMYND10 interacts with LRRC6, another cytoplasmically localized protein altered in PCD. Using a fly model of PCD, we conclude that ZMYND10 is a cytoplasmic protein required for IDA and ODA assembly and that its variants cause ciliary dysmotility and PCD with laterality defects

Impact du COVID-19 et du confinement sur les troubles psychiques anxieux et dépressifs chez les patients consultant en médecine générale à Marseille

Introduction : en raison de la pandémie de COVID-19, la plupart des gouvernements ont adopté des mesures de confinement, ayant de fortes répercussions sur la santé mentale. De nombreuses études ont analysé les conséquences sur la santé mentale en population générale, mais à notre connaissance encore peu ont identifié les facteurs de risque en santé mentale et aucune étude ne portait sur une patientèle de médecine générale à Marseille. Par ailleurs, du fait d’un système de soins psychiatriques fortement perturbé, le médecin généraliste (MG) s’est retrouvé en première ligne face aux problématiques de santé mentale.Objectifs de l’étude : l’objectif principal de notre étude était de déterminer la prévalence des troubles anxio-dépressifs pendant la troisième vague de COVID-19 chez les patients consultant en médecine générale à Marseille. Les objectifs secondaires étaient d’identifier les facteurs de risque de troubles anxio-dépressifs, d’analyser le rôle du MG dans l’accompagnement des patients et de décrire le comportement des participants vis-à-vis des mesures sanitaires.Méthode : il s’agit d’une étude observationnelle transversale analytique. Le recrutement a eu lieu dans un cabinet de médecine générale à Marseille. Les participants ont répondu à une enquête standardisée en ligne, entre le 25 mars 2021 et le 2 mai 2021. L'anxiété et la dépression ont été évaluées à l'aide de l'échelle Hospital Anxiety and Depression (HADS).Résultats : 301 patients ont répondu à l'enquête (taux de réponse 21%). Les scores moyens de HADS-A (anxiété), HADS-D (dépression) et HADS-T (anxio-dépression) étaient respectivement de 8,77 (±4,16), 6,13 (±3,99) et 14,9 (±7,31). La prévalence de l’anxiété était de 33% (n=99) et de la dépression de 15% (n=45). Les femmes, les 18-24 ans, les catégories socio-professionnelles plus modestes et les chômeurs présentaient des niveaux d’anxio-dépression significativement plus élevés. Les patients satisfaits de leur prise en charge en santé mentale par leur MG présentaient des niveaux d’anxio-dépression plus bas et ceux ayant discuté du COVID avec leur MG déclaraient une meilleure adoption des gestes barrières. Conclusion : la prévalence des troubles anxio-dépressifs a fortement augmenté par rapport aux données pré-pandémiques. Les femmes, les 18-24 ans et les personnes au statut économique précaire semblent particulièrement à risque et nécessitent une attention particulière. Le MG a lui put jouer un rôle protecteur en favorisant une meilleure santé mentale et une plus forte adhésion aux gestes barrières. Des actions de santé spécifiques pourraient viser à soutenir ces populations fragiles en s’attaquant aux déterminants de la santé mentale et plus largement aux inégalités sociales de santé
