The relevance of the midlatitude conveyor belt model to Mediterranean cyclones (MCs) is examined using data from two winters. Eight MCs, which exhibit typical midlatitude cyclone structure, were ...scrutinized and their conveyor belts were examined. The analysis was based on satellite imagery, isentropic wind maps, vertical cross-sections of potential and equivalent potential temperatures, and air back-trajectories. The conveyor belts found in the studied MCs were similar to the common features of midlatitude cyclones, except for three aspects. First, the warm conveyor belt was not associated with massive organized cloudiness in five of the eight cyclones since it consisted of dry air originated from the Saharan desert. Second, the anticyclonic branch of the cold conveyor belt was not found in half of the MCs. Third, the dry air intrusion originated north of the cyclone and extended southward around it, unlike its common midlatitudinal northwest–southeast orientation. This is consistent with the relatively small baroclinic vertical-westward tilt of the cyclones analyzed.
Introduction
For healthcare workers, good work-related well-being positively affects enthusiasm, efficiency, and job satisfaction. Conversely, poor well-being is associated with burnout and negative ...patient outcomes. During times of crises, it is difficult to balance professional responsibilities with well-being.
Objective
This study aimed to evaluate the degree of well-being among nurse practitioners in Israel who worked in COVID-19 units or allied units during the delta wave.
Methods
This was a web-based, cross-sectional study. Nurse practitioners who worked within the COVID-19 units in Israeli hospitals were asked to complete several questionnaires: a sociodemographic questionnaire, the Subjective Happiness Scale, the Mental Health Continuum-Short Form, and the Center for Epidemiologic Studies-Depression.
Results
Forty-nine nurse practitioners participated in the survey. Scores from the Subjective Happiness Scale and the Mental Health Continuum-Short Form indicate that most nurses have relatively positive mental health. Conversely, scores on the Center for Epidemiologic Studies indicated that participants are at risk for clinical depression. There was a positive moderate association between the number of years worked as a nurse practitioner and depression and a moderate negative association between the number of years worked as a nurse practitioner and happiness.
Conclusions
Understanding how nurses’ mental health is impacted during crises can provide healthcare systems with tools to prevent negative outcomes. This, in turn, may contribute to a lower burnout rate, higher satisfaction from work, and better patient outcomes.
A 42-year-old man was injured twice in his left eye. The first injury resulted in a lacerated skin wound on the forehead, eyebrows and lids, a broken orbital wall and rim, and a small rupture of the ...sclera at 12 o'clock. The second injury caused a rupture of his left globe. During the operation a large scleral rupture, 1 mm from the limbus, a prolapsed iris, vitreous, and the lens were found under the conjunctiva. The would had been cleaned, the prolapsed iris and vitreous were excised, and the scleral wound sutured. One year after the injury the visual acuity was 6/10 with an aphakic contact lens correction and binocular vision was established. Diagnostic features and indications for immediate repair are discussed.
Two cases, those of a man and a woman, developed retinal periphlebitis after hormonal treatment for infertility and contraceptives, respectively. Both had a unilateral severe decrease in visual ...acuity, and a central scotoma and defect in color vision were also present. The fundus had retinal edema, especially of the macula, a hyperemic disc with blurred margins, normal arteries, congested veins, and marked sheathing along the main veins, with retinal hemorrhages in the inferior half of the retina. Fluorescein angiography showed a delayed filling of the veins in the affected retina and late staining of these veins. Since there was severe visual impairment in each case, systemic adrenocorticosteroids were administered, and a rapid improvement in visual acuity occurred. In one patient, a trace Marcus-Gunn sign, a few small paracentral scotomas, and a defect in color vision were permanent sequelae.
126 cases of retinal breaks treated in our department by photocoagulation during a period of 10 years (1963-1973) were selected for a close annual follow-up. Eliminated from the study were cases of ...macular holes, breaks which developed in an eye after retinal detachment surgery, and cases in which a close follow-up was impossible for various reasons. The study includes symptomatic retinal breaks in myopic, non-myopic, and aphakic eyes as well as asymptomatic holes which were found in the undetached fellow eye. Four eyes treated by photocoagulation (3.2%) developed a retinal detachment. The causes of failures and complications, such as retinal detachment, vitreous haemorrhage, and macular pucker, are discussed.
A combined trabeculectomy and cataract extraction was performed on 46 eyes of 39 patients. The average follow-up period was of 27 months. The intraocular pressure remained controlled without the need ...of postoperative medication in 33 eyes (71.74%); 12 eyes (26.09%) needed further medical treatment; and in one eye the pressure remained uncontrolled and further surgery was necessary. After surgery the visual acuity improved considerably and the complications were few. The combined procedure has many advantages. The patient is cured by one surgical procedure, his visual acuity improves, his intraocular pressure is reduced to normal, and he is relieved from the need for medication postoperatively. By a single stay in hospital and by reducing the number of postoperative medical routine controls the expenses are reduced considerably. Owing to these advantages the combined procedure deserves to be considered in cases of glaucoma and cataract.
