Prophylaxis of Macular Edema with Intravitreal Ranibizumab in Patients with Diabetic Retinopathy after Cataract Surgery: A Pilot Study

2011

The purpose of this study was to evaluate the effectiveness of intravitreal ranibizumab (Lucentis, Genentech, South San Francisco, Calif, USA) combined with cataract surgery for the prevention of clinically significant macular edema (CSME) in patients with diabetic retinopathy (DR). This prospective interventional case series included fifty-four eyes of 54 patients with a previous diagnosis of nonproliferative diabetic retinopathy (NPDR) without macular edema preoperatively. Subjects were assigned in a 1 : 1 ratio to receive an intraoperative intravitreal ranibizumab injection (n=27) or not (control group,n=27) associated with standardised phacoemulsification surgery. The main outcome measu…

Secondary Vitrectomy with Internal Limiting Membrane Plug due to Persistent Full-Thickness Macular Hole OCT-Angiography and Microperimetry Features: …

2020

Purpose. To study the features in OCT-angiography and microperimetry in eyes with persistent full-thickness macular hole (FTMH) closed with the secondary plana vitrectomy (PPV) with autologous internal limiting membrane (ILM) plug. Methods. Secondary PPV was performed with closing the persistent FTMH with ILM plug, C3F8 tamponade, and face-down positioning. Four patients were followed for 6 months with best corrected visual acuity (BCVA) measurement, SD-OCT and OCT-A, and microperimetry. The results were compared with the fellow eye; in two patients, it was the healthy eye, and in two remaining eyes, successfully closed FTMH after primary PPV. Results. ILM flap was integrated in all cases w…

Premedication with midazolam in intellectually disabled dental patients: Intramuscular or oral administration? A retrospective study

2016

Background: The use of midazolam for dental care in patients with intellectual disability is poorly documented. The purpose of this study was to determine which method of premedication is more effective for these patients, 0.15 mg/kg of intramuscular midazolam or 0.3 mg/kg of oral midazolam. Material and Methods: This study was designed and implemented as a non-randomized retrospective study. The study population was composed of patients with intellectual disability who required dental treatment under ambulatory general anesthesia from August 2009 through April 2013. Patients were administered 0.15 mg/kg of midazolam intramuscularly (Group IM) or 0.3 mg/kg orally (Group PO). The predictor v…

Visual Impairment Is Associated With Depressive Symptoms—Results From the Nationwide German DEGS1 Study

2018

Introduction: Visual impairment is associated with a variety of co-morbidities including physical and mental health in industrial countries. Our aim is to examine associations between self-reported impairment and depressive symptoms in the German population. Methods: The point prevalence of self-reported visual impairment in Germany was computed using data from the German Health Interview and Examination Survey for adults from 2008 to 2011 (N=7.783, 50.5% female, age range 18-79 years). Visual impairment was surveyed by two questions, one for seeing faces at a distance of 4 meters and one for reading newspapers. Depressive symptoms were evaluated with the PHQ-9 questionnaire and two-week pr…

Cardiovascular outcomes after cardiac resynchronization therapy in cardiac amyloidosis

2021

Abstract Aims Cardiac resynchronization therapy (CRT) is highly effective in dilated cardiomyopathy (DCM) patients with impaired left ventricular ejection fraction (LVEF) and left bundle block branch. In cardiac amyloidosis (CA) patients, left ventricular dysfunction and conduction defects are common, but the potential of CRT to improve cardiac remodelling and survival in this particular setting remains undefined. We investigated cardiovascular outcomes in CA patients after CRT implantation in terms of CRT echocardiographic response and major cardiovascular events (MACEs). Methods and results Our retrospective study included 47 CA patients implanted with CRT devices from January 2012 to Feb…

Association of Stress and Musculoskeletal Pain With Poor Sleep: Cross-Sectional Study Among 3,600 Hospital Workers

2018

Background: While acute stress and pain are part of our inherent survival mechanisms, persistent stress and pain can negatively impact health and well-being. This may also lead to poor sleep and thus a lack of recovery. This study investigated the influence of stress and musculoskeletal pain on sleep quality. Methods: A total of 3,593 Danish hospital workers replied to a questionnaire about work and health. Pain intensity was evaluated using subjective values as an average of 9 body parts. Stress was assessed using the full version of Cohen's Perceived Stress scale. Sleep quality was rated using 3 questions on sleep characteristics. Associations between stress and pain (mutually adjusted pr…

Renin-Angiotensin System Blockade and Mortality in Patients With Hypertension and COVID-19 Infection

2020

To determine the effect renin-angiotensin system blockers on the outcome in patients with hypertension and concurrent COVID-19 infection, we searched PubMed, the Cochrane Library, and Google Scholar for relevant articles. Twelve studies with a total of 16,101 patients met the inclusion criteria. The mortality rate among the users of angiotensin converting enzyme inhibitors or angiotensin receptor blockers was 12.15% and in non-users it was 14.56% (risk ratio 0.70, 95% CI [0.53-0.91], P < 0.007). There was no difference in the risk of death between the use of angiotensin converting enzyme inhibitors and angiotensin receptor blockers (risk ratio 1.09, 95% CI [0.90 -1.32]). We conclude tha…

Blood pressure in chronic kidney disease stage 5D—report from a Kidney Disease: Improving Global Outcomes controversies conference

2010

Management of blood pressure (BP) in patients with chronic kidney disease receiving dialysis (stage 5D) provides a significant challenge for healthcare professionals. The association between BP and cardiovascular disease risk has been well studied in the general population; however, in dialysis patients, physiological and dialysis-related mechanisms influencing BP are complex, and the associated risk is poorly understood. In stage 5D, BP is determined by the complex interplay of fluid volume and prescription of post-dialysis target weight, sodium load, the renin–angiotensin and sympathetic nervous systems, and diverse exogenous factors, such as administration of erythropoiesis-stimulating a…

Preoperative Botulinum Toxin and Progressive Pneumoperitoneum in Loss of Domain Hernias-Our First 100 Cases

2020

Objectives: Preoperative botulinum toxin type A (BT) and progressive pneumoperitoneum (PPP) are useful tools in the preparation of patients with loss of domain hernias (LODH). The purpose of our retrospective study is to report our experience in the treatment of 100 consecutive patients with LODH, with the combined use of these techniques. Methods: Of the 753 patients operated on for ventral incisional hernia between June 2010 and December 2018 in our hospital, 100 patients with LODH were analyzed retrospectively. Diameters of abdominal cavity and hernia sac, and volumes of incisional hernia (VIH) and abdominal cavity (VAC) were calculated from CT scan, based on the index of Tanaka. Results…

Frailty and risk of complications in head and neck oncologic surgery. Systematic review and dose-response meta-analysis

2021

Background There is emerging evidence that frail individuals present a decreased physiological reserve, decreased ability to maintain homeostasis, and increased vulnerability to stressors. The concept of frailty has become increasingly recognized as a valuable measure in oncological surgical patients, including those with head and neck cancer. Preoperative screening for frailty may provide an individualized risk assessment that can be used by an interdisciplinary team for preoperative counseling and to improve outcomes. The aim of this meta-analysis was to evaluate the relationship between frailty and the risk of major postoperative complications in frail individuals submitted to head and n…
