Stem cell transplantation with rehabilitation therapy presents an effective stroke treatment. Here, we discuss current breakthroughs in stem cell research along with rehabilitation strategies that may have a synergistic outcome when combined together after stroke. Indeed, stem cell transplantation offers a promising new approach and may add to current rehabilitation therapies. By reviewing the pathophysiology of stroke and the mechanisms by which stem cells and rehabilitation attenuate this inflammatory process, we hypothesize that a combined therapy will provide better functional outcomes for patients. Using current preclinical data, we explore the prominent types of stem cells, the existing theories for stem cell repair, rehabilitation treatments inside the brain, rehabilitation modalities outside the brain, and evidence pertaining to the benefits of combined therapy. In this review article, we assess the advantages and disadvantages of using stem cell transplantation with rehabilitation to mitigate the devastating effects of stroke. / Revisión por pares

Cardiac rehabilitation has been shown to improve outcomes in patients with heart disease. Determining the effect cardiac rehabilitation (CR) has on the quality of life (QOL) of patients who have participated in a CR program is an important health outcome measure. The majority of QOL studies have focused primarily on younger patients with little attention devoted to the elderly. The purpose of this descriptive, comparative study was to determine whether participation or lack of participation in a CR program will affect the perceived QOL of elderly patients with coronary heart disease (CHD). The Sickness Impact Profile (SIP) was used to measure QOL of two groups, those who participated in CR and those who did not participate in CR. A demographic inventory was used to collect sociodemographic information. The mean SIP scores for the physical and psychosocial dimensions, as well as the overall SIP score revealed less dysfunction for the group that participated in CR thereby indicating a better quality of life for this group. However, other methods of data analysis were not statistically significant. Although the results of this study were not statistically significant, they may be of clinical significance as indicated by the mean SIP scores and the percent of non-overlap scores. Education of the older patient and the public about the beneficial effects of CR on QOL is a prime responsibility of nurse practitioners.

Bakgrund: Visuell snö är ett perceptionsstörande neurooftalmologiskt tillstånd karakteriserat av bestående mikroskopiska flimrande prickar som täcker hela det bilaterala synfältet. Det kan liknas vid att titta genom en flimrande tv-skärm, eller Gaussiskt brus. Några etablerade riktlinjer för behandling finns inte för närvarande. Syfte: Denna litteraturstudie syftar till att undersöka tillgänglig litteratur rörande effekten av olika behandlingsalternativ för tillståndet visuell snö.  Metod: En sökning utfördes i sökmotorn PubMed den 20 mars 2023. Söksträngen som användes var “visual snow” OR “visual snow syndrome” AND “treatment”. Fler studier tillkom genom granskning av referenser. Begränsningar i urvalet baserades på relevans rörande behandling, samt en litteraturstudie utförd av Eren & Schankin publicerad 2020. Den här studien tar upp arbeten tillkomna därefter, totalt 8 artiklar utgivna mellan 2020-2022.  Resultat: Vår studie har lyckats identifiera behandlingsalternativ för visuell snö i form av neuro-optometrisk synträning, farmaceutika, kosttillskott, kiropraktik, filterglasögon, antikroppar, mydriatika, synstimuli, samt repetitiv transkraniell magnetstimulering. Samtliga studier utfördes på deltagare med bekräftad och diagnostiserad visuell snö, antingen som isolerat symptom, som del av Visual Snow Syndrome, eller som sekundärt tillstånd. Positiva behandlingssvar med partiell remission förekommer, samt enstaka fall av total remission. Samtliga inkluderade studier har sina begränsningar, en gemensam sådan är svårigheten att kvantifiera symptomen. Med hjälp av enkäter och symptomdagböcker har 7 av 8 studier visat på viss subjektiv effekt av behandling, av okänd magnitud.  Slutsats: Patofysiologin bakom visuell snö är ännu inte klarlagd. I dagsläget finns ingen generellt applicerbar behandling för visuell snö, men enstaka fall av total remission samt ett antal fall av partiell remission förekommer i litteraturen. Vid behandling av patienter med visuell snö bör hänsyn tas till individuella patienters förutsättningar, komorbiditet och tidigare prövad behandling. / Background: Visual snow is a neuro-ophthalmological perception disorder characterized by persistent microscopic flickering dots covering the bilateral field of vision. It can be described as looking through TV static, or Gaussian noise. There are currently no established guidelines regarding treatment. Purpose: This literature survey aimed to investigate available literature regarding the efficacy of different therapeutic approaches for the condition of visual snow.   Method: A search was performed in the PubMed search engine on March 20, 2023. The search string used was “visual snow” OR “visual snow syndrome” AND “treatment”. Further studies were added through references. Restrictions in article selection were based on relevance regarding treatment, as well as a review by Eren & Schankin published in 2020. This study covers subsequent articles, a total of 8 articles published between 2020-2022. Results: Our study has identified therapeutic approaches to visual snow in the form of neuro-optometric rehabilitation therapy, pharmaceuticals, nutraceuticals, chiropractic treatment, filter glasses, antibodies, mydriatics, visual stimuli, and repetitive transcranial magnetic stimulation. All participants had confirmed and diagnosed visual snow either as an isolated symptom, as part of Visual Snow Syndrome, or as a secondary condition. Positive responses with partial remission occur, as well as occasional total remissions. All included studies have some limitations, a common one being the difficulty in quantifying the symptoms. Using questionnaires and symptom diaries, 7 out of 8 studies have shown some subjective effect of treatment of unknown magnitude.  Conclusion: The pathophysiology behind visual snow is not yet fully understood. Currently, there is no generally applicable treatment for visual snow, but occasional cases of total remission and a number of cases of partial remission appear in the literature. When treating patients with visual snow, the individual patient’s conditions, comorbidity and previously tried treatment should be taken into account.
