A previous abdominal scar is generally considered as a challenge for breast reconstruction using abdominal flaps. Since it may interfere with the perfusion of abdominal tissue and weaken the abdominal fascia, many plastic surgeons are concerned about the theoretical risk of postoperative complications. This study aims to assess the effects of previous scar on complications in abdominal flap-based breast reconstruction.
This systematic review of the literature was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline using MEDLINE, Ovid, and Cochrane databases in March 2020. All studies comparing the complication rates between patients with previous abdominal scars and control group without a scar were included. However, articles such as case series fewer than 10 patients, letters and animal studies were excluded.
A total of 2109 patients underwent 2792 abdominal flap tissue transfers for breast reconstruction in the 11 studies reviewed. A previous scar increased the risk of overall flap complications (RR 1.12; 95% CI, 0.95-1.32; fixed-effect model, I
= 13%) and donor-site complications (RR 1.35; 95% CI, 1.13-1.62; fixed-effect model, I
= 42%, p > 0.05). In particular, the risk of donor-site wound problem was significantly higher than that in the control group (RR 1.83; 95% CI, 1.35-2.46; fixed-effect model, I
= 19%, p > 0.05).
This study result showed that the previous scar increased the risk for all types of complications compared with the control group. In patients with a vertical midline scar, it requires careful preoperative planning with CT angiography and attentive follow-up. However, with careful preoperative planning and an appropriate strategy, it is possible to overcome the detrimental effect of previous scar.

Arterio-venous malformations (AVMs) of the ear are a rare entity and their management should be decided in a dedicated multidisciplinary team (MDT) setting. The aim of this study is to describe the distinct anatomical patterns of the auricular AVMs in our unit and propose a combined interventional radiological and surgical approach.
All consecutive patients presenting with AVMs of the ear and reviewed by the Vascular Anomalies MDT between 2014 and 2019 were included in this study. Signs, symptoms, diagnostic investigations and operative findings were collected prospectively.
After reviewing our nine patients, we identified four anatomical patterns of auricular AVMs I involves just a component of the ear and should undergo embolization followed by excision and reconstruction without significant loss of form; II affects the superior two-thirds of the ear, sparing the lobule and part of the conchal bowl; these patients should undergo embolization, excision and monitoring before formal reconstruction of the ear is offered; III involves the entire ear and should undergo embolization and pinnectomy; if there is no recurrence, the patients can be offered either a carved-rib cartilage reconstruction or a prosthesis, depending on the quality of the surrounding soft-tissues; IV involves the ear and surrounding tissue, making surgical management and subsequent reconstruction extensive.
The management of auricular AVMs is based on the extent of the ear involved. We feel that our combined interventional radiological and surgical approach will aid the management of these complex patients.

Undoubtedly, denervation of the first carpometacarpal (CMC-1) joint does represent a promising surgical treatment alternative for patients suffering from persistent CMC-1-joint osteoarthritis. A surgical standard, however, has not yet been implemented, as technical approach and indication of this procedure still show great variances. In order to contribute to an evidence-based standardization of CMC-1-joint denervation, we would like to share our considerations, approaches and anatomical findings in this comment.
To develop and assess the feasibility in daily practice of four comorbidity checklists, for common use in rheumatoid arthritis (RA), axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA).
A multidisciplinary panel of experts on comorbidity was established. Data from the GECOAR, GECOAX and GECOAP projects were analysed and a narrative literature review in Medline on RA, axSpA and PsA comorbidity was performed in order to select the most relevant and common comorbidities across the three diseases. With these results and those obtained from a focus group of patients, in a nominal group meeting, the experts generated preliminary checklists. These were afterwards modified by an external evaluation by two associations, a patients' association and an association of health professionals related to rheumatology. As a result, the final checklists were generated. A cross-sectional study was conducted to test the feasibility of three of the checklists in daily practice, in which eight health professionals evaluated the checklists in five patients with RA, five with axSpA and five with SpA.
Four comorbidity checklists were designed, three for health professionals (one to assess current comorbidity, one on prevention/health promotion and one with the referral criteria to other health professionals), and another for patients. The feasibility study showed them to be simple, clear, and useful for use in routine clinical practice.
The use of specific and common checklists for patients with RA, axSpA and PsA is feasible and might contribute favorably to their prognosis as well as in daily practice.

Caffeine is rapidly absorbed with complete bioavailability following oral dosing. selleck compound Switching between parenteral and oral administration requires no dose adjustments. Caffeine has wide interindividual pharmacodynamic variability and a wide therapeutic index in preterm newborns. Thresholds of measurable efficacy on respiratory drive have been documented at plasma levels around 2 mg/L. At these low levels, caffeine competitively inhibits adenosine receptors (A1 and A2A). The toxicity threshold is ill-defined and possibly as high as 60 mg/L which can be lethal in adults. High doses of caffeine may produce better control of apnea. link2 However, at high systemic drug concentrations, the pharmacodynamic actions of caffeine become more complex and worrisome. They include inhibition of GABA receptors and cholinergic receptors in addition to adenosine receptor inhibition, intracellular calcium mobilization and actions on adrenergic, dopaminergic and phosphodiesterase systems. The role of pharmacogenomic factors as determinants of neonatal pharmacologic response and clinical effects remains to be explored.
To investigate whether generalized ligamentous laxity (GLL) really is a contraindication for use of the modified Broström operation to treat chronic lateral ankle instability (CLAI).
Case series and cohort studies of the clinical outcomes of the use of the modified Broström operation to treat patients with CLAI and GLL were systematically reviewed and a meta-analysis conducted.
A total of 447 patients (458 ankles) from 2 case series and 3 cohort studies were systematically analyzed, with mean follow-up times that ranged from 12 to 108 months. Postoperative foot and ankle values analyzed included foot and ankle outcome scores, foot and ankle ability measurements, Karlsson-Peterson ankle scores, American orthopedic foot and ankle society (AOFAS) ankle-hindfoot scores, Tegner activity level scores, anterior talar translations (ATT), talar tilt angles (TTA) and adverse events. Reliable postoperative ankle stability was achieved in CLAI patients with GLL in the 2 case series without major complications. Sutudified Broström operation being used to treat CLAI. However, some augmentation operations may be combined with the classic modified Broström operation, especially for those patients with preoperative Beighton scores ≥7, or with abnormal ATT and TTA in the contralateral ankle. This assertion should be further confirmed by a prospective, large-sample cohort and control study focused on this special population who are at a higher risk of developing postoperative instability.

Recent data suggest significant underutilization of hypomethylating agents (HMAs) that are recommended treatments for patients with myelodysplastic syndromes (MDS) with refractory anemia with excess blasts (RAEB). The study objective was to assess the degree of HMA use and predictors of HMA underuse in this population.
This was a retrospective study including patients diagnosed with the RAEB form of MDS between January 2011 and December 2015 using the Surveillance, Epidemiology, and End Results-Medicare linked database. Patients were excluded if they had< 1 year of continuous enrollment before diagnosis or received stem cell transplant or lenalidomide during the follow-up period. HMA non-peristence was defined as use of< 4 cycles (3-10 HMA days/28 days) of HMAs or a gap of≥ 90 days between consecutive cycles. Patients were characterized as HMA never-users, HMA-persistent users, and HMA-non-persistent users. Descriptive statistics were used to summarize patient characteristics. Multivariable logistic regression was used to assess predictors of HMA underuse and persistence.
Of the 1190 patients, 526 (44%) were never-users, 295 (25%) were non-persistent users, and 369 (31%) were persistent users. Age at diagnosis (eg, 66-70 years vs.≥ 80 years; odds ratio [OR], 2.36; 95% confidence interval [CI], 1.56-3.56), marital status (single vs. married; OR, 0.67; 95% CI, 0.51-0.89), National Cancer Institute comorbidity index (≥ 3 vs. link3 0-1; OR, 0.62; 95% CI, 0.46-0.83), and performance status (poor vs. good; OR, 0.67; 95% CI, 0.51-0.87) were significantly associated with HMA underuse.
Several demographic and clinical factors were associated with underuse of HMAs. There is need for a better understanding of suboptimal HMA use and its relationship with clinical response.

The symptoms appear to be more severe in males older than 65 and people with underlying health conditions; approximately one in five individuals could be at risk worldwide. The virus's sequence was rapidly established days after the first cases were reported and identified an RNA virus from the Coronaviridae family closely related to a Betacoronavirus virus found in bats in China. SARS-CoV-2 is the seventh coronavirus known to infect humans, and with the severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS), the only ones to cause severe diseases. Lessons from these two previous outbreaks guided the identification of critical therapeutic targets such as the spike viral proteins promoting the virus's cellular entry through the angiotensin-converting enzyme 2 (ACE2) receptor expressed on the surface of multiple types of eukaryotic cells. Although several therapeutic agents are currently evaluated, none seems to provide a clear path for a cure.
