Health care workers' influenza vaccination: motivations and mandatory mask policy

BACKGROUND: Vaccination of health care workers (HCW) against seasonal influenza (SI) is recommended but vaccination rate rarely reach >30%. Vaccination coverage against 2009 pandemic influenza (PI) was 52% in our hospital, whilst a new policy requiring unvaccinated HCW to wear a mask during patient care duties was enforced. AIMS: To investigate the determinants of this higher vaccination acceptance for PI and to look for an association with the new mask-wearing policy. METHODS: A retrospective cohort study, involving HCW of three critical departments of a 1023-bed, tertiary-care university hospital in Switzerland. Self-reported 2009-10 SI and 2009 PI vaccination statuses, reasons and demographic data were collected through a literature-based questionnaire. Descriptive statistics, uni- and multivariate analyses were then performed. RESULTS: There were 472 respondents with a response rate of 54%. Self-reported vaccination acceptance was 64% for PI and 53% for SI. PI vaccination acceptance was associated with being vaccinated against SI (OR 9.5; 95% CI 5.5-16.4), being a physician (OR 7.7; 95% CI 3.1-19.1) and feeling uncomfortable wearing a mask (OR 1.7; 95% CI 1.0-2.8). Main motives for refusing vaccination were: preference for wearing a surgical mask (80% for PI, not applicable for SI) and concerns about vaccine safety (64%, 50%) and efficacy (44%, 35%). CONCLUSIONS: The new mask-wearing policy was a motivation for vaccination but also offered an alternative to non-compliant HCW. Concerns about vaccine safety and efficiency and self-interest of health care workers are still main determinants for influenza vaccination acceptance. Better incentives are needed to encourage vaccination amongst non-physician HCW.

Mesure de l'impact de l'implication des proches aidants de patients hospitalises dans une unité de soins psychiatriques aigus sur eux-mêmes

Le but de cette étude est de mesurer ainsi que de qualifier l'impact de l'implication des proches aidants de patients hospitalisés dans des unités de soins psychiatriques aigus sur eux-mêmes. Le cadre conceptuel utilisé est celui du fardeau des familles de Schene (1990). Il différencie les parties objectives et subjectives du fardeau familial. La récolte de données a été réalisée à l'aide de l'Involvement Evaluation Questionnaire (IEQ). Les résultats de cette étude montrent que les proches aidants souffrent d'un niveau d'inquiétude élevé, 3.8 sur une échelle de Likert à 5 questions, ainsi que d'un niveau de tension à 2.44 sur une échelle de Likert à 5 questions. Des associations ont été trouvées. L'augmentation de la durée du trouble diminue l'inquiétude, avec une valeur ρ de 0.048. Le fait d'être habitué à la situation a également un impact en diminuant la tension, avec une valeur ρ de 0.002. Plus on est « habitué à la situation », avec une valeur ρ de -0.021, moins le proche est inquiet par rapport à la situation du patient. Ainsi que, plus le patient est jeune, plus le proche aidant ressent de tension, avec une valeur ρ de 0.008. Ces résultats, peu généralisables au vu du petit échantillon (n=24), pourraient toutefois impliquer une réflexion approfondie sur l'accueil, la place et le soutien des proches aidants de patients souffrants de troubles psychiatriques hospitalisés dans une unité de soins aigus de la part des infirmières.

Long recognized as the standard general reference in the field, this completely revised edition of Grainger and Allison's Diagnostic Radiology provides all the information that a trainee needs to master to successfully take their professional certification examinations as well as providing the practicing radiologist with a refresher on topics that may have been forgotten. Organized along an organ and systems basis, this resource covers all diagnostic imaging modalities in an integrated, correlative fashion and focuses on those topics that really matter to a trainee radiologist in the initial years of training

Congenital inferior vena cava anomalies: a review of findings at multidetector computed tomography and magnetic resonance imaging

Inferior vena cava anomalies are rare, occurring in up to 8.7% of the population, as left renal vein anomalies are considered. The inferior vena cava develops from the sixth to the eighth gestational weeks, originating from three paired embryonic veins, namely the subcardinal, supracardinal and postcardinal veins. This complex ontogenesis of the inferior vena cava, with multiple anastomoses between the pairs of embryonic veins, leads to a number of anatomic variations in the venous return from the abdomen and lower limbs. Some of such variations have significant clinical and surgical implications related to other cardiovascular anomalies and in some cases associated with venous thrombosis of lower limbs, particularly in young adults. The authors reviewed images of ten patients with inferior vena cava anomalies, three of them with deep venous thrombosis. The authors highlight the major findings of inferior vena cava anomalies at multidetector computed tomography and magnetic resonance imaging, correlating them the embryonic development and demonstrating the main alternative pathways for venous drainage. The knowledge on the inferior vena cava anomalies is critical in the assessment of abdominal images to avoid misdiagnosis and to indicate the possibility of associated anomalies, besides clinical and surgical implications.

Pulmonary 64-MDCT angiography with 50 mL of iodinated contrast material in an unselected patient population: a feasible protocol

Abstract Objective: To propose a protocol for pulmonary angiography using 64-slice multidetector computed tomography (64-MDCT) with 50 mL of iodinated contrast material, in an unselected patient population, as well as to evaluate vascular enhancement and image quality. Materials and Methods: We evaluated 29 patients (22-86 years of age). The body mass index ranged from 19.0 kg/m2 to 41.8 kg/m2. Patients underwent pulmonary CT angiography in a 64-MDCT scanner, receiving 50 mL of iodinated contrast material via venous access at a rate of 4.5 mL/s. Bolus tracking was applied in the superior vena cava. Two experienced radiologists assessed image quality and vascular enhancement. Results: The mean density was 382 Hounsfield units (HU) for the pulmonary trunk; 379 and 377 HU for the right and left main pulmonary arteries, respectively; and 346 and 364 HU for the right and left inferior pulmonary arteries, respectively. In all patients, subsegmental arteries were analyzed. There were streak artifacts from contrast material in the superior vena cava in all patients. However, those artifacts did not impair the image analysis. Conclusion: Our findings suggest that pulmonary angiography using 64-MDCT with 50 mL of iodinated contrast can produce high quality images in unselected patient populations.

Pèls a la llengua

Si sou calbs i voleu deixar de ser-ho, o si la vostra parella és calba i enyoreu aquells cabells llargs i espessos que lluïa a l'època hippie, esteu de sort. Però aneu alerta, perquè si sou d'aquelles persones que els agrada dir que no té pèls a la llengua, potser ara us en sortiran. O almenys això és el que hom pot pensar després de sentir una de les darreres notícies de ciència de gran ressò mediàtic: s'ha aconseguit que a un ratolí modificat genèticament per no tenir cap pèl li'n creixin. Els artífexs han estat els membres d'un equip de recerca de l'Institut Kennedy Krieger de la Johns Hopkins University, dels EUA, encapçalat per Catherine Thompson. I esclar, molts ja s'imaginen lluint llargues i espesses cabelleres on ara només tenen lluentors [...].
