Komplikationen bei skleranahtfixierter Kunstlinsenimplantation

Die Sklerafixation einer Kunstlinse ist bei insuffizientem Kapselapparat eine häufig gewählte Versorgung. Als nachteilig gilt das potenzielle Komplikationsprofil. Analyse des postoperativen Komplikationsprofils. In dieser monozentrischen, retrospektiven Analyse einer konsekutiven Fallserie von Patienten mit standardisierter, skleranahtfixierter Kunstlinsenimplantation (2007 bis 2017) wurden die dokumentierten Komplikationen in „dauerhaft visusbedrohend“ (Endophthalmitis, Aderhautblutung, Ablatio retinae) und „klinisch relevant, aber nicht dauerhaft visusbedrohend“ (z. B. Blutungen, Hypotonie) kategorisiert. Zudem wurde der Zeitpunkt der erstmaligen Dokumentation der Komplikationen erfasst und in 3 Zeiträume eingeordnet (0 bis 3, 4 bis 30 und ≥31 Tage). Vorliegend handelt es sich um das bislang größte publizierte Patientenkollektiv einer Studie mit Skleranahtfixierung einer Hinterkammerlinse (HKL). Es wurden 338 Augen von 338 Patienten in die Studie eingeschlossen (Frauen: 47 %), die mediane Nachbeobachtungszeit betrug 60 Tage (min.: 1 Tag, max.: 5833 Tage). In 68 % der Fälle wurden Komplikationen dokumentiert. „Dauerhaft visusbedrohende Komplikationen“ traten bei 3 % (n = 10) der Patienten auf. Als „klinisch relevante Komplikationen“ wurden ermittelt: okuläre Hypotension auf Werte ≤10 mm Hg (n = 119; 35 %), entrundete Pupille (n = 93; 28 %), Hyphäma, Iris- oder Glaskörperblutungen (n = 34; 10 %), Sekundärglaukom (n = 32; 9 %) und Iris-Capture (n = 17; 5 %); 41 % der Komplikationen traten innerhalb der ersten 3 Tage und 70 % innerhalb der ersten 30 Tage auf. Zu Revisionsoperationen kam es bei 4,5 % (n = 15) der Patienten. Obwohl bei ca. zwei Dritteln aller Eingriffe Komplikationen auftraten, war die Zahl der dauerhaft visusbedrohenden Komplikationen gering. Die Sklerafixation der Kunstlinse ist weiterhin ein vertretbarer Eingriff.     

Walking speed as a predictor of community mobility and quality of life after stroke

Background: Community mobility (CM) is considered a part of community reintegration that enhances Quality of Life (QoL). Achieving an appropriate gait speed is essential in attaining an independent outdoor ambulation and satisfactory CM.

Objective: The aim of this study was to identify whether gait speed is a predictor of CM and QoL in patients with stroke following a multimodal rehabilitation program (MRP).

Methods: This was a baseline control trial with 6-months follow-up in an outpatient rehabilitation setting at a university hospital. Twenty-six stroke survivors completed the MRP (24 sessions, 2 days/wk, 1 hr/session). The MRP consisted of aerobic exercise, task-oriented exercises, balance exercises and stretching. Participants also performed an ambulation program at home. Outcome variables were: walking speed (10-m walking test) and QoL (physical and psychosocial domains of Euroquol and Sickness Impact Profile).

Results: At the end of the intervention, comfortable and fast walking speed increased by an average of 0.16 (SD 0.21) (*p < .05) and 0.40 (SD 0.51) (**p < .001) m/s, respectively. After the intervention, all participants achieved independent outdoor ambulation with an increase of 34.14 of walking minutes/day in the community and a decrease of sitting time of 95.45 minutes/day. Regarding QoL there were increased mean scores on the physical and psychosocial dimensions of Euroquol and the Sickness Impact Profile, respectively (**p < .001).

Conclusions: The results suggest that improved walking speed after the MRP is associated with CM and higher scores in QoL. These findings support the need to implement rehabilitation programs to promote increased speed.     

Dietary fat intake and metabolic syndrome in adults: A systematic review

Background and aimsThe metabolic syndrome (MetS) is a cluster of coexisting cardiovascular risk factors. The role of specific dietary fats was reemphasized by dietary recommendations. This systematic review aims to assess evidence for the effect of dietary fat intake on MetS occurrence and reversion in adults.Methods and ResultsThe MEDLINE database was used to search the existing literature. We included observational studies that analyzed dietary fat intake in adults with MetS and clinical trials that compared the effects of different dietary fat diets on MetS and/or its components. Thirty articles were selected (14 observational and 16 clinical trials), and we included information of dietary fat and fatty acids as well as MetS, body mass index, cholesterol, hypertension, and diabetes in adults. SFA intake was found to be positively associated with MetS components. Most of the observational reviewed studies found beneficial associations between MUFA and PUFA (including n-3 and n-6 subtypes) intake and MetS components. Clinical trials also supported the benefits of MUFA- or PUFA-enriched diets (including low-fat diets) in reducing MetS.ConclusionsThe effects of dietary SFAs on MetS will be influenced by other specific nutrients. Replacement of SFA by MUFA and PUFA has been associated with a decrease in MetS. Dietary recommendations should emphasize on different qualities of fat intake, not only to reduce total fat intake, to obtain health benefits in adults.

2019 Canadian Cardiovascular Society Position Statement for Transcatheter Aortic Valve Implantation

Transcatheter aortic valve implantation (TAVI) or replacement has rapidly changed the treatment of patients with severe symptomatic aortic stenosis. It is now the standard of care for patients believed to be inoperable or at high surgical risk, and a reasonable alternative to surgical aortic valve replacement for those at intermediate surgical risk. Recent clinical trial data have shown the benefits of this technology in patients at low surgical risk as well. This update of the 2012 Canadian Cardiovascular Society TAVI position statement incorporates clinical evidence to provide a practical framework for patient selection that does not rely on surgical risk scores but rather on individual patient evaluation of risk and benefit from either TAVI or surgical aortic valve replacement. In addition, this statement features new wait time categories and treatment time goals for patients accepted for TAVI. Institutional requirements and recommendations for operator training and maintenance of competency have also been revised to reflect current standards. Procedural considerations such as decision-making for concomitant coronary intervention, antiplatelet therapy after intervention, and follow-up guidelines are also discussed. Finally, we suggest that all patients with aortic stenosis might benefit from evaluation by the heart team to determine the optimal individualized treatment decision.
