These studies were randomized controlled trials that used rESWT for muscle spasm in stroke patients with conventional treatments as controls. There are no specific restrictions on the duration of treatment, the type of reESWT, or the severity of symptoms. These studies must have assessed at least one of the following outcome mesurements: visual analog scale (VAS) for pain, Ashwerth measure for muscle tone or external rotation range of motion (ER ROM). RevMan 5.3 software was used to check the quality of included studies. For continuous variables, mean difference (MD) or standardized MD (SMD) with CI 95% were derived. For dichotomous data, event proportions and sample sizes were extracted. \u0000Results: In the conducted investigations, it was found that 7 studies investigated the effectiveness of rESWT  treatments after the intervention in comparison with conventional treatment in terms of reducing pain intensity. In total, all 7 studies showed that the rESWT intervention was effective in reducing pain intensity compared to conventional treatments (MD, –0.97 [95% CI, –2.13 to –0.42], P < .00001, I2 = 71%). Compared with traditional treatments, the effectiveness of rESWT plus routine treatments on muscle tone after intervention was assessed in terms of Ashwerth critrion  in 4 trials (SMD, 1.13 [95% CI, 0.46-1.23], P < .00001, I2 =  59%). ER ROM was used to reflect the ROM, which was assessed in 4 RCTs. Because of the limited number of studies, ER ROM was measured immediately after treatment in all included studies. The pooled result of the included studies showed that the heterogeneity was high and unacceptable (MD, 10.31 [95% CI, 2.47–16.18], P < .003, I2 = 81%). \u0000Conclusion: The results of this research indicated that rESWT treatment can be used as a safe and non-invasive method to quickly reduce spasticity and increase joint range of motion in stroke patients. But more research on the long-term effects of rESWT as well as the factors influencing its effectiveness to reduce spasticity and comparison with other new treatment protocols is suggested.","PeriodicalId":42860,"journal":{"name":"Journal of Contemporary Medical Sciences","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41298706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research has investigated the efficacy of stem cells and stromal vascular fraction (SVF) in many types of injuries. SVF has advantages for its heterogenous population of cells and avoidance of culturing and ethical issues. SVF can be isolated either enzymatically or mechanically. Enzymatically isolated SVF reduced inflammation and enhanced neovascularization and re-epithelization in the treatment of burn injury. This study highlighted the efficacy of applying mechanically isolated SVF on the early inflammatory phase of deep partial-thickness burn by investigating toll-like receptor 4 (TLR4) signaling pathway. \u0000Methods: 30 male Wistar rats with deep partial-thickness burns were assigned into: the control group, silver sulfadiazine (SSD) cream group, and mechanically isolated SVF group. Morphological, histopathological evaluation of inflammation, and immunohistochemical analysis for (TLR4, TNF-α, IL‐1β, and IL-6) were evaluated for the first eight days post-treatment. \u0000Results: Morphologically, the SVF group significantly reduced edema and increased wound bed dryness on day one compared to the control group (P=0.0001) and to the SSD group (P=0.001). Histopathologically, the SVF group significantly reduced inflammation four days post-treatment compared with the control group (P=0.045). The SVF group significantly reduced TLR4 protein expression on days four and eight post-treatment compared with the control group (P= 0.001, P= 0.042, respectively). The TNF-α protein expression in the SVF group was significantly lower on days four and eight post-treatment compared with the control group (P= 0.046, P= 0.046, respectively) and with the SSD group (P= 0.008, P= 0.001, respectively). The IL‐1β expression was significantly reduced in the SVF group compared to the control group on day four post-treatment (P= 0.017). There were no significant differences in IL-6 expressions between all groups on both days. \u0000Conclusion: The mechanical isolation of SVF has an early anti-inflammatory impact on deep partial-thickness burn injury. This effect could be through inhibiting TLR4, TNF-α, and IL‐1β pathways. This could partially explain the mechanism behind SVF efficacy in the healing process of burn injury.","PeriodicalId":42860,"journal":{"name":"Journal of Contemporary Medical Sciences","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46424122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report here a case of a Saudi female patient that was initially diagnosed at a few months old with beta-thalassemia major and was treated with regular blood transfusions and iron overload management. At the time of our sample collection, the patient was recently transferred to King Abdul Aziz University Hospital. Genetic testing was performed to identify the disease-contributing variant of beta-thalassemia using TaqMan genotyping of six common beta-thalassemia variants (negative results). NGS targeted HBB gene sequencing which did not reveal any related variants. MLPA was performed to rule out alpha thalassemia diagnosis. The use of whole genome sequencing revealed a rare missense variant in the PKLR gene c.1015G>A (D339N) in a homozygous state that correlates to her severe phenotype.

Ciprofloxacin resistance was identified by detecting a mutation in gyrA and parC. \u0000Results: The biofilm intensity significantly decreased (P < 0.05) concerning S. aureus isolates and insignificantly (P > 0.05) concerning E. coli isolates. Yet, one E. coli isolate's biofilm was significantly decreased (P < 0.05) linearly with increasing eDNA. Of considerable interest, the addition of eDNA led to a significant increase (P < 0.05) in the biofilm of the two-tested P. aeruginosa isolates. Moreover, eDNA participated in transferring Ciprofloxacin resistance to the sensitive isolate when it presents in its biofilm. \u0000Conclusion: eDNA has a dual effect on bacterial biofilms either supportive or suppressive following bacterial species per se. Also, it seems to play an important role in antibiotic resistance within the biofilm.","PeriodicalId":42860,"journal":{"name":"Journal of Contemporary Medical Sciences","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43602588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
