Background: Capsular contracture is common in breast augmentation and reconstruction surgery. The present systematic review discusses the safety of textured and smooth implants in the submuscular position. Methods: A literature search was conducted on PubMed and EMBASE from inception until June 2020. The primary outcome was reduction of capsular contracture (Baker grade); others included time of capsular contracture onset, implant position/rupture rate/surface, hematoma/seroma risk, surgeon assessment and patient satisfaction. A total of 7731 patients were included from six publications. Results: The overall risk rate for capsular contracture increased from 7.6 to 25% in 10 years. The capsular contracture rates in textured and smooth implants were 3–14% and 6–20%, respectively, and no significant difference between implants was observed when the implants were placed submuscularly. Submuscular placement and textured implants also reduced the incidence of other complications. Conclusion: This systematic review suggests that appropriate placement reduces capsular contracture rate, irrespective of implant surface.

Background. Acupuncture might have effectiveness in relieving the symptoms of chronic urticaria. There are currently no systematic reviews of acupuncture for chronic urticaria published in English.Objective. We conducted a systematic review to assess the effectiveness and safety of acupuncture for chronic urticaria.Methods. A systematic review and meta-analysis of randomized, controlled trials were performed. The primary outcome was global symptom improvement.Results. We included 6 studies with 406 participants. Three trials showed significant difference between acupuncture and drugs in global symptom improvement (relative risk 1.37; 95% CI 1.11–1.70;P=0.003). As an adjuvant to medication, acupuncture was also beneficial for global symptom improvement (relative risk 1.77; 95% CI 1.41–2.22;P<0.01). There were no severe adverse events related to acupuncture.Limitations. Some methodological limitations were observed. The overall risk of bias in the 6 included trials was high and all included RCTs were conducted in China and published in Chinese. Besides, the lack of proper control groups and the use of different rating methods and cut-offs in the included trials also made the evidence of this review limited.Conclusions. Acupuncture might be effective and safe for chronic urticaria in relieving symptoms, based on a low level of evidence. To draw a reliable conclusion, more high quality trials are needed in the future. This trial is registered with PROSPEROCRD42015015702.

Present Systematic Review

The COVID-19 pandemic altered activities of societies, forced closures at the national level in several countries, populations had to isolate themselves at home. Different studies have been initiated that allow us to understand the changes in behaviors related to physical activity and sedentary lifestyle in populations. The objective of this work was the analysis of the importance of physical activity in COVID-19 times. A systematic review was carried out and a questionnaire was applied to the population that performs physical activity in parks of Puebla City, Mexico. The results of the present systematic review suggest that engaging in even light physical activity during the pandemic can help eliminate some of the negative impacts on the health of populations. Since those who experience a decrease in physical activity also have higher levels of stress and anxiety. The data obtained from the questionnaire applied to the study population showed a participation of 54% men and 46% women, ages 14-70 years for men and 18-69 years for women. Regarding the time they perform physical activity, men reported 2-3 days (40.74%), 4-5 days (29.62%) and >5 days (29.62%), women 2-3 days (17.39%), 4-5 days (52.17%) and >5 days (30.43%). Regarding the time that men spend sitting <3 hours (14.81%), 4-8 hours (70.37%) and >8 hours (14.81%), women <3 hours (13.04%), 4-8 hours (65.21%) and >8 hours (21.73%). The variables of practiced time of physical activity, days a week, minutes a day and hours sitting between men and women showed no significant difference (P>0.05). It is recommended that populations get involved in physical activities in order to maintain a better quality of life and thus mitigate the phenomena associated with confinement due to the pandemic.

Objectives: To assess the effects and safety of β-blockers in hospitalized patients with burns. Methods: A systematic review and meta-analysis of the literature. A broad search was conducted to identify all randomized controlled trials (RCTs) comparing β-blockers to control in hospitalized patients with burns. The primary outcome was 3-month all-cause mortality. Secondary outcomes were clinical patient-relevant end points. We subgrouped results by children/adults and burn severity. Risk of bias was assessed using the individual domain approach. Results: Four RCTs reported in 11 publications were included. Primary outcome of mortality was assessed in children (2 trials, n = 424) and adults (2 trials, n = 148) with severe burns. No significant difference was found between propranolol and control for mortality (risk ratio [RR] = 0.82, 95% CI = 0.48-1.39, 4 trials with broad confidence intervals in adults and children), sepsis (RR = 0.81, 95% CI = 0.46-1.43, 2 trials), and survivors’ length of stay (absolute mean difference = 2.53, 95% CI = −2.58–7.63, 3 trials). There was no significant difference in bradycardia (RR = 1.33, 95% CI = 0.77-2.3, 2 trials), hypotension (RR = 1.26, 95% CI = 0.73-2.17, 3 trials), or cardiac arrhythmia (RR: 2.97, 95% CI: 0.12-71.87, 1 trial). The evidence was graded as very low certainty, due to trial’s internal risk of bias, imprecision, and possible selective reporting. Conclusions: No sufficient evidence was found to support or refute an advantage for β-blocker use in children or adults after burns. Additional studies are needed to create a consensus and formulate practice guidelines on the optimal β-blocker to use, indications for initiation, and duration of treatment.

Abstract Background Current guidelines include fecal microbiota transplantation (FMT) in the management of recurrent Clostridioides difficile infections (CDI). However, FMT protocols are often facility dependent, and one variable is whether proton pump inhibitors (PPI) are given during preparation. Theoretically, PPIs reduce acidity and protects the transplanted microbiome for the most potent dose. On the other hand, PPIs have also been shown to negatively alter the microbiome and increase the risk of CDI. We conducted a systematic review of the literature to study PPI use on the efficacy of FMT delivered by the trans-oral route. Methods We searched PubMed/Medline, Cochrane Library, Embase, Scopus, and Web of Science through December 16th, 2018 using variations of keywords “fecal microbiota transplant” and “Clostridium difficile infection” with 4210 results. Two independent authors reviewed and excluded studies with unrelated topics, abstracts, case reports, or a low level of evidence. Studies with data on trans-oral FMT, PPI use, and the success rate were included. Final review yielded 11 studies including randomized controlled, case–control, cohort, retrospective and prospective trials. The primary outcome was the rate of FMT failure, defined as recurrence of symptoms with positive CDI testing at follow-up. Results Out of 233 included patients, 131 received a PPI per FMT protocol resulting in 27 cases of treatment failure. There were 23 cases of recurrence out of 102 patients who did not receive pre-FMT PPI. The primary outcome occurred in 20.6% in the group with PPI use vs. 22.6% in the group without (RR 0.91; CI 0.56 - 1.50). Limitations include the lack of studies directly comparing outcomes with respect to PPI use, and inability to control possible confounders such as chronic PPI use, amount of stool transplanted, and pre-FMT antibiotics. Conclusion We did not find a significant difference in efficacy between FMT protocols with regard to PPI use. It is possible that the theoretical benefit from increased survival of transplanted microbiota is offset by negative effects associated with PPIs. We suggest that routine use of PPIs in FMT be reconsidered in the absence of clear benefit. Further investigation is needed to optimize protocols for safety and efficacy.

Abstract Background The relative risks and benefits of various textured breast implants are the focus of considerable discussion. Studies have suggested different risk-benefit profiles for different implant surface topographies. Objectives The study aim was to provide device-specific, quantitative information on Mentor’s imprinted Siltex Textured breast implants with respect to textured surface characteristics and ISO 14607 classification, risk of breast implant–associated anaplastic large cell lymphoma (BIA-ALCL), and risk-reduction benefits relative to smooth implants. Methods Surface metrology was performed. Data for smooth and Siltex implants from the prospective MemoryGel Core Study were evaluated by Kaplan-Meier analysis for the most frequently occurring postoperative complications in augmentation and reconstruction leading to subsequent reoperation. Results The overall average surface roughness for Siltex MemoryGel and MemoryShape implants was 29.5 and 36.1 µm, respectively. A statistically significantly lower rate of reoperation in patients with Siltex compared with smooth devices over 10 years was observed for both capsular contracture in subglandular primary augmentation patients (2.02% vs 19.84%) and for asymmetry in primary reconstruction patients (3.88% vs 11.1%). Conclusions Surface analysis demonstrated that Siltex implants fall within the ISO 14607 category of “microtexture” breast implants. These devices exhibited a rare risk of BIA-ALCL (0.0012%) based on the most extensive data available. Relative to smooth implants, these Siltex devices provided risk-reduction benefits for the most common reason of reoperation in patients who underwent primary augmentation (capsular contracture) or primary reconstruction (asymmetry) in the Core Study. These findings provide valuable risk-benefit information for surgeons and their patients. Level of Evidence: 2

A variety of dietary supplements are presently available as slimming aids, but their efficacy has not been proven. One such slimming aid is the bean extract, Phaseolusvulgaris. The aim of the present systematic review is to evaluate the evidence for or against the efficacy of P. vulgaris. Electronic and non-electronic searches were conducted to identify relevant human randomised clinical trials (RCT). Hand searches of bibliographies were also conducted. No age, time or language restrictions were imposed. The eligibility of studies was determined by two reviewers independently, and the methodological quality of the included studies was assessed. We identified eleven eligible trials, and six were included. All the included RCT had serious methodological flaws. A meta-analysis revealed a statistically non-significant difference in weight loss between P. vulgaris and placebo groups (mean difference (MD) − 1·77 kg, 95 % CI − 3·33, 0·33). A further meta-analysis revealed a statistically significant reduction in body fat favouring P. vulgaris over placebo (MD − 1·86 kg, 95 % CI − 3·39, − 0·32). Heterogeneity was evident in both analyses. The poor quality of the included RCT prevents us from drawing any firm conclusions about the effects of P. vulgaris supplementation on body weight. Larger and more rigorous trials are needed to objectively assess the effects of this herbal supplement.

Abstract Background Previous studies have reported decreased rates of capsular contracture associated with the use of textured surface breast implants placed in the subglandular plane during breast augmentation. However, since the publication of these studies, our understanding of the pathophysiology of capsular contracture, as well as the surgical techniques utilized to minimize bacterial contamination of the implant, have advanced considerably. Objectives The purpose of this study was to re-evaluate the relation between implant surface texturization and capsular contracture rates for breast implants placed in the subglandular plane during primary breast augmentation. Methods Retrospective chart review was performed of all primary subglandular breast augmentation procedures involving the use of either smooth or textured round silicone gel implants, with or without simultaneous mastopexy. The primary outcome measures included clinically significant capsular contracture (Baker grade III/IV) and revision surgery for capsular contracture. Results Between 2010 and 2017, 526 patients underwent primary subglandular breast augmentation with either smooth (n = 212) or textured (n = 314) round silicone gel implants; 248 patients underwent breast augmentation, whereas 278 underwent breast augmentation-mastopexy. Average follow-up was 756 days in the textured group and 461 days in the smooth group. Five cases of capsular contracture were observed in the textured group, and 7 cases of capsular contracture were observed in the smooth group (P = 0.20). Conclusions Smooth surface implants placed in the subglandular plane were not at a significantly increased risk of capsular contracture compared with textured surface implants. We suggest that adherence to a surgical technique focused on minimizing bacterial contamination of the implant is of greater clinical significance than implant surface characteristics when discussing capsular contracture.

The Impact

OBJECTIVEPlatelet-rich plasma (PRP) is a biological agent obtained by centrifuging a sample of blood and retrieving a high concentration of platelets and plasma components. The concentrate is then stimulated for platelet secretion of various growth factors and cytokines. Although it is not widely used in clinical practice, its role in augmenting bony union among patients undergoing spinal fusion has been assessed in several clinical studies. The objective of this study was to perform a systematic review and meta-analysis of the existing literature to determine the efficacy of PRP use in spinal fusion procedures.METHODSA comprehensive literature search was conducted using PubMed, Scopus, and EMBASE for studies from all available dates. From eligible studies, data regarding the fusion rate and method of assessing fusion, estimated blood loss (EBL), and baseline and final visual analog scale (VAS) scores were collected as the primary outcomes of interest. Patients were grouped by those undergoing spinal fusion with PRP and bone graft (PRP group) and those only with bone graft (graft-only group).RESULTSThe literature search resulted in 207 articles. Forty-five full-text articles were screened, of which 11 studies were included, resulting in a meta-analysis including 741 patients. Patients without PRP were more likely to have a successful fusion at the last follow-up compared with those with PRP in their bone grafts (OR 0.53, 95% CI 0.34–0.84; p = 0.006). There was no statistically significant difference with regard to change in VAS scores (OR 0.00, 95% CI −2.84 to 2.84; p > 0.99) or change in EBL (OR 3.67, 95% CI −67.13–74.48; p = 0.92) between the groups.CONCLUSIONSThis study found that the additional use of PRP was not associated with any significant improvement in patient-reported outcomes and was actually found to be associated with lower fusion rates compared with standard grafting techniques. Thus, PRP may have a limited role in augmenting spinal fusion.

Abstract Background Direct-to-implant (DTI) breast reconstruction is increasingly performed as the preferred method of immediate breast reconstruction following mastectomy. The proposed advantages of DTI over two-stage tissue expander (TE)/implant reconstruction relate to fewer surgical procedures. This systematic review and meta-analysis aims to evaluate the safety and efficacy of DTI versus conventional TE/implant breast reconstruction. Method A systematic review was performed (PubMed, Embase, Scopus) to identify relevant studies that compared outcomes between DTI and TE/Implant reconstructions. Publications up to October 2020 were included. The primary outcome was overall complication rate. Secondary outcomes included infection rate and implant loss. Results Nineteen studies, including 32,971 implant-based breast reconstructions, were analysed. Median age was 48 years. Mean BMI was 25.9. There was no statistically significant difference between the two groups. Duration of follow up ranged from 1-60 months. Overall complications were significantly more likely to occur in the DTI group (OR 1.81 [1.17-2.79]). Overall complications refers to all reported complications including seroma, haematoma, would dehiscence, infection, skin necrosis and capsular contracture. Implant loss was also significantly higher in the DTI cohort (OR 1.31 [1.12-1.78]). There was no significant difference in infection rates between the two groups. Subgroup analyses, focusing on high-powered multicentre studies showed that the risks of overall complications were significantly higher in the DTI group (OR 1.51 [1.06-2.14]). Conclusions This meta-analysis demonstrates significantly greater risk of complications and implant loss in the DTI breast reconstruction group. These findings serve to aid both patients and clinicians in the decision-making process regarding implant reconstruction following mastectomy
