Effect of vision therapy on measures of oculomotor function of patients presenting with post-concussion syndrome

Oculomotor dysfunction is a common symptom of post-concussion syndrome (PCS). By use of a retrospective analysis approach, the efficacy of Vision Therapy (VT) for the treatment of PCS related symptoms of the visual system was investigated. Overall, 56 patients were selected for inclusion in this study, all of which presented with clinical impairment of at least one measure of oculomotor functioning. Activities related to VT were wide-ranging and case-dependent, but all aimed to improve one of the five main areas of visual function. Following completion of VT, all patients demonstrated statistically or clinically significant improvements, as defined by use of Morgan’s Norms, in at least one measure of oculomotor functioning related to PCS. In general, improvements in measures of oculomotor functioning were greatest for near point of convergence, vergence facility and accommodative facility. Patients receiving 20 sessions of VT had improved and less variable outcomes when compared to those receiving 5-10 sessions of VT. In addition, VT was found to improve symptoms of visual discomfort in patients presenting with PCS. Results of this retrospective analysis demonstrate significant improvements in measured outcomes for all patients receiving VT and support VT as a treatment option for symptoms of PCS

Effet de la thérapie visuelle sur les mesures de la fonction oculomotrice chez les patients atteints du syndrome de post-commotion

La dysfonction oculomotrice est un symptôme courant du syndrome de post-commotion (SPC). Dans cette étude, on a étudié rétrospectivement l’efficacité de la thérapie visuelle (TV) pour le traitement des symptômes liés au SPC par rapport au système visuel. Dans l’ensemble, 56 patients ont été sélectionnés, qui présentaient tous une déficience sur le plan clinique d’au moins une mesure du fonctionnement oculomoteur. Les activités liées à la TV étaient grandement variées et établies au cas par cas, mais elles visaient toutes à améliorer l’une des cinq principales fonctions visuelles. À la suite de la TV, tous les patients ont démontré des améliorations statistiquement ou cliniquement significatives, comme définies par l’utilisation des normes de Morgan, dans au moins une mesure du fonctionnement oculomoteur lié au SPC. En général, les améliorations les plus importantes des mesures du fonctionnement oculomoteur concernaient le point de convergence proche, la flexibilité de vergence et la flexibilité d’accommodation. Les patients qui ont suivi 20 séances de TV avaient de meilleurs résultats (aussi moins variables) que ceux qui ont suivi entre 5 et 10 séances. De plus, la TV a diminué les symptômes d’inconfort visuel chez les patients qui présentaient un SPC. Les résultats de cette analyse rétrospective démontrent des améliorations importantes dans les résultats mesurés pour tous les patients qui ont suivi une TV et appuient la TV comme option de traitement pour les symptômes du SPC

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.
