Single Treatment, Single Depth Superficial Microfocused Ultrasound with Visualization for Rhytid Improvement
Authors: Lowe Stephen 
Published: July 2021

Background:
Standard lifting and tightening protocols with microfocused ultrasound with visualization (MFU-V, Ultherapy) comprise the use of multiple transducer depths. We developed a shortened, single depth treatment protocol for patients seeking skin rejuvenation.

Methods:
Single-center, prospective case series. Subjects with static periorbital wrinkles, perioral wrinkles, or accordion lines had a single MFU-V treatment comprising up to 340 lines (periorbital 120, perioral 100, and accordion 120) with the superficial depth transducer (10.0 MHz/1.5 mm). Efficacy was assessed using established rating scales as well as clinician- and subject-reported Global Aesthetic Improvement Scales at baseline, 90, and 180 days, and each subject served as their own control. Adverse events were documented.

Results:
Nine subjects, women aged 38–64, received treatment. At 180 days, post treatment clinicians reported visible improvements in periorbital lines (6/6 cases), accordion lines (5/6 cases), and perioral lines (3/6 cases). Subjects’ self-assessments mirrored those of the clinicians, reporting improvements in accordion lines (5/6 cases improved, 1/6 cases much improved), periorbital lines (3/6 cases improved, 3/6 cases much improved) and perioral lines (2/6 cases improved, 2/6 cases much improved). Subject-rated satisfaction was high (accordion lines 6/6 cases, periorbital lines 4/6 cases and perioral lines 4/6 cases). All subjects experienced mild, transient erythema; in one subject, wheals persisted for 24 hours, resolving on application of mild topical corticosteroid.

Conclusions:
Shortened protocol, single depth MFU-V treatment was well-tolerated. It provided aesthetic improvements in periorbital and accordion lines, and to a lesser extent in perioral lines. Its utility as a noninvasive therapy for superficial skin rejuvenation warrants further investigation.

Published: July 2021

Background:
Chronic ulcers represent a challenge for healthcare professionals and a large expense for national health care systems for their difficulty in achieving complete healing and for their high incidence of recurrence. With the progressive aging of the general population, the incidence of these injuries will only increase, further affecting the public health budget, hence the need to find new strategies for their management. The purpose of this study was to share the experience of the Complex Operational Unit of Plastic Surgery of the University Hospital of Padua with fluorescent light energy therapy, outlining its role in the treatment of chronic ulcers in the daily use outside the previous EUREKA study.

Methods:
In this case series study, we enrolled 15 patients with chronic ulcers of any etiology between January 2018 and July 2019 and we treated them using fluorescence light energy. We evaluated efficacy and safety endpoints reporting data in excel files completed by medical staff during the study.

Results:
The study confirms the effectiveness of fluorescent light energy inducing chronic ulcer healing, regardless of etiology, or at least preparing the lesions for a skin graft closure surgery. The system showed a low rate of complications established by patient adherence to treatment. Patients also reported a reduction in pain both at home and during outpatient dressings.

Conclusion:
Based on our experience, fluorescent light energy shows an excellent safety and efficacy profile in chronic ulcers no more responsive to traditional dressings and/or surgery.

Published: July 2021

Background:
Patients who undergo breast cancer treatment require psychosocial and aesthetic rehabilitation. Advantages of breast reconstruction in-patient rehabilitation are well known. Oncoplastic organ-preserving surgery offers aesthetically better results, yet is often considered less safe than more radical procedures. We compared the aesthetic and psychological outcomes in patients undergoing breast reconstruction and oncoplastic breast cancer treatment.

Methods:
In total, 1130 patients who received either breast reconstruction or oncoplastic breast cancer surgery were included in the study. Patients were classified into two groups. Group 1 included 510 patients who received breast reconstruction surgery. Group 2 included 620 patients who received oncoplastic surgery. The following aspects were compared between the two groups: demographics, tumor progression, and immunohistochemical aspects, complications, hospitalization stay, and psychological and aesthetic outcomes.

Results:
Patients in the oncoplastic group showed statistically significant higher psychosocial and aesthetic outcomes, as well as lower incidence of complications, revision rate, disease progression, and recurrence. The majority of oncoplastic patients were treated in early stages of breast cancer.

Conclusion:
Offering superior treatment results, oncoplastic organ-preserving surgery should be favored in patients with earlier stages of cancer progression.
Neuroplasticity following Nerve Transfer of the Anterior Interosseous Nerve for Proximal Ulnar Nerve Injuries
Authors: Nyman Erika , Nyman Torbjörn , Rubensson Carin , Thordstein Magnus 
Published: July 2021

Background:
Injuries to the ulnar nerve at or above proximal forearm level result in poor recovery despite early microsurgical repair, especially concerning the intrinsic motor function of the hand. To augment the numbers of regenerating axons into the targeted muscles, a nerve transfer of the distal branch of the median nerve, the anterior interosseous nerve, to the ulnar motor branch has been described.

Methods:
Two patients with severe atrophy of the intrinsic hand muscles following an initial proximal ulnar nerve repair had surgery with an end-to-side transfer of the anterior interosseous nerve to the ulnar motor branch at the wrist level. Outcome and neuroplasticity were prospectively studied using questionnaires, clinical examinations, electroneurography, electromyography, somatosensory evoked potentials at pre nerve transfer and 3-, 12-, and 24-months post nerve transfer as well as navigated transcranial magnetic stimulation at pre nerve transfer and 3- and 12-months post nerve transfer.

Results:
Successively improved motor function was observed. Complete reinnervation of intrinsic hand muscles was demonstrated at 12- to 24-months follow-up by electroneurography and electromyography. At the cortical level, navigated transcranial magnetic stimulation detected a movement of the hot-spot for the abductor digiti mini muscle, originally innervated by the ulnar nerve and the size of the area from where responses could be elicited in this muscle changed over time, indicating central plastic processes. An almost complete reinnervation of the pronator quadratus muscle was also observed.

Conclusion:
Both central and peripheral plastic mechanisms are involved in muscle reinnervation after anterior interosseous nerve transfer for treatment of proximal ulnar nerve injuries.

Published: July 2021

Summary:
Physicians attempted to continue providing patient care through the SARS-CoV2 (COVID-19) pandemic. Surgeons embraced telemedicine as patient evaluation transitioned from physical encounters to virtual appointments. However, there is a paucity in the literature on the utility of telemedicine within plastic surgery or how it can meet patients’ needs. A survey study was created to assess surgeons’ involvement and experience with telemedicine. Subjective experience was assessed on a five-point Likert scale (1 = strongly disagree, 2 = disagree, 3 = neutral, 4 = agree, 5 = strongly agree). This survey was distributed to the members of the American Society of Plastic Surgeons. Data were collected and analyzed via RedCap. Of the total 177 plastic surgeons who responded, 139 (78.5%) surgeons reported the implementation of telemedicine during the pandemic. Plastic surgeons felt that they were able to establish rapport (3.9 ± 0.9), meet the goals of the encounter (3.6 ± 1.0), and efficiently evaluate patients (3.5 ± 1.2). Plastic surgeons reported their overall experience was between helpful and neutral (3.2 ± 1.3). Most plastic surgeons have implemented telemedicine in their practice. The majority of telemedicine use was for breast, cosmetic, and reconstructive patient care. Telemedicine was most frequently used for initial patient screening and routine postoperative visits. Surgeons plan to continue using telemedicine when appropriate for patient screening and routine or unexpected postoperative visits in the future. Many have found utility of telemedicine in providing patient care and it is likely that telemedicine will be a part of routine practice moving forward.

Published: July 2021

Abstract
Modern breast surgery was first introduced in the United States in 1962 with the use of silicone gel-filled breast implants. Over the past 6 decades, development of breast implants has been challenged by a variety of influencers including aesthetic appeal in shape, texture, and material; challenges in managing outcomes such as contracture, disease, and rupture; and public perception of risks associated with implants. In 1992, silicone breast prostheses were banned by the US Food and Drug Administration with exception for use in breast reconstruction, congenital deformities, or to replace existing implants.
The ban led to heightened concerns about implants and possible disease manifestations. Knowledge of the historical evolution of breast prostheses is useful for understanding the associated risks and outcomes unique to each breast implant era. This article aimed to explore characteristics of breast implants by generation, with implications for diagnosis and assistance to modern surgical planning for novice plastic surgeons.
Duodenal ulcer perforation: A systematic literature review and narrative description of surgical techniques used to treat large duodenal defects

Published: July 2021

BACKGROUND
There is no consensus on optimal surgical treatment of large duodenal defects arising from perforated ulcers, even though such defects are challenging to repair and inadequate repair is associated with high morbidity and mortality. The aim of this study was to carry out a systematic literature review of different surgical techniques used to treat large duodenal perforations, provide a narrative description of these techniques, and propose a framework for approaching this pathology.

METHODS
PubMed/MEDLINE database was searched for articles published in English between January 1, 1970, and December 1, 2020. Studies describing surgical techniques used to treat giant duodenal ulcer perforation and their outcomes in adult patients were included. No quantitative analysis was planned because of the heterogeneity across studies.

RESULTS
Out of 960 identified records, 25 studies were eligible for inclusion. Two randomized controlled trials, one case-control trial, three cohort studies, 14 case series, and 5 case reports were included. Eight main surgical approaches are described, ranging from simple damage-control operations, such as the omental plug and triple-tube techniques, all the way to complex resections, such as gastrectomy.

CONCLUSION
Evidence on surgical treatment of large duodenal defects is of poor quality, with the majority of studies corresponding to Oxford levels 3b-4. Current evidence does not support any single surgical technique as superior in terms of morbidity or mortality, but choice of technique should be guided by several factors including location of the perforation, degree of duodenal tissue loss, hemodynamic stability of the patient, as well as expertise of the operating surgeon.

Published: July 2021

BackgroundMinority ethnic groups and immigrants have been hit disproportionally hard by COVID-19 in many developed countries, including Norway. Most transmissions of SARS-CoV-2 occur in households.MethodsUsing individual-level registry data of all Norwegian residents we compared infections across all multi-person households. A household with at least one member born abroad was defined as an immigrant household. For the subset of households where at least one person tested positive for SARS-CoV-2 from August 1st 2020 to May 1st 2021, we calculated secondary attack rates (SARs) as the percent of other household members testing positive within 14 days after the first household member tested positive. Logistic regression model was used to adjust for sex, age, household composition and geography.ResultsAmong all multi-person households in Norway (n=1 421 642), immigrant households (n=341 604) comprised more members on average (3.2) than households with only Norwegian-born members (2.8). The share of immigrant households where at least one member had been tested, was 56% (vs 49% in the households with only Norwegian-born members), and the share where at least one member was infected was 3.7% (vs 1.4% in households with only Norwegian-born members). Secondary attack rates were higher in immigrant (32%) than Norwegian-born households (20%). Results differed considerably by country of birth, with secondary attack rates particularly high in households from Syria, Iraq, Turkey, and Pakistan, also after adjustment for sex, age, household composition and geography.ConclusionSARS-CoV-2 is more frequently introduced into multi-person immigrant households than into households with only Norwegian-born members, and transmission within the household occurs more frequently in immigrant households. The results are likely related to living conditions, family composition or differences in social interaction, emphasizing the need to prevent introduction of SARS-CoV-2 into these vulnerable households.

Published: July 2021

AbstractAdoptive chimeric antigen receptor (CAR)-modified T or NK cells (CAR-T/NK) have emerged as a novel form of disease treatment. Lentiviral vectors (LVs) are commonly employed to engineer T/NK cells for the efficient expression of CARs. This study reported for the first time the influence of single-promoter and dual-promoter LVs on the CAR expression and cytotoxicity of engineered NK cells. Our results demonstrated that the selected CAR exhibits both a higher expression level and a higher coexpression concordance with the GFP reporter in HEK-293T or NK92 cells by utilizing the optimized single-promoter pCDHsp rather than the original dual-promoter pCDHdp. After puromycin selection, the pCDHsp produces robust CAR expression and enhancedin vitrocytotoxicity of engineered NK cells. Therefore, infection with a single-promoter pCDHsp lentivector is recommended to prepare CAR-engineered cells. This research will help to optimize the production of CAR-NK cells and improve their functional activity, to provide CAR-NK cell products with better and more uniform quality.

Published: July 2021

AbstractTranscranial Magnetic Resonance Guided Focused Ultrasound (MRgFUS) can be used in conjunction with intravenous microbubbles to open the blood brain barrier (BBB) in discrete brain regions. This method is limited by the microbubble dose, the amount of energy that can be safely delivered across an intact skull, and the inability to target areas of the brain outside of central brain regions. We find that N2O administration substantially decreases the required dose of microbubbles and/or focused ultrasound pressure while still reliably opening the blood brain barrier. Additionally, we observe that the use of nitrous oxide improves the delivery of adeno-associated virus (AAV9) vector when compared to medical air. Our findings may help overcome focused ultrasound limitations and improve targeted delivery of therapeutics in humans.One Sentence SummaryNitrous Oxide potentiates Blood Brain Barrier opening with Focused Ultrasound and enhances viral vector delivery.

AbstractRoot system architecture (RSA) is a target for breeding because of the interest to develop crops with roots that use nutrients and water more effectively. Breeding for RSA requires phenotypic diversity in populations amenable to QTL identification to provide markers for large breeding programs. This study examined the variation for root traits across the parents of two multi-parent advanced generation inter-cross (MAGIC) wheat populations from NIAB and CSIRO for 16 days in an upgraded version of the non-invasive, germination paper-based phenotyping platform, GrowScreen-PaGe. Across all parents, total root length varied up to 1.90 fold, root biomass 2.25 fold and seminal root angle 1.16 fold. The CSIRO parents grew faster, exhibited slightly wider seminal root angle and produced larger root systems compared to NIAB parents. Lateral root lengths, leaf lengths and biomass contrasted most between fastest (Robigus - NIAB and AC Barrie - CSIRO) and slowest growing parents (Rialto - NIAB and G204 Xiaoyan54 - CSIRO). Lengths of lateral and total root, and leaf number and length had moderate to high heritability (0.30-0.67) and repeatability. Lengths of lateral roots and leaves are good targets for enhancing wheat crop establishment, a critical stage for crop productivity.
Rapid shifts in mitochondrial tRNA import in a plant lineage with extensive mitochondrial tRNA gene loss

Published: July 2021

AbstractIn most eukaryotes, transfer RNAs (tRNAs) are one of the very few classes of genes remaining in the mitochondrial genome, but some mitochondria have lost these vestiges of their prokaryotic ancestry. Sequencing of mitogenomes from the flowering plant genus Silene previously revealed a large range in tRNA gene content, suggesting rapid and ongoing gene loss/replacement. Here, we use this system to test longstanding hypotheses about how mitochondrial tRNA genes are replaced by importing nuclear-encoded tRNAs. We traced the evolutionary history of these gene loss events by sequencing mitochondrial genomes from key outgroups (Agrostemma githago and Silene [=Lychnis] chalcedonica). We then performed the first global sequencing of purified plant mitochondrial tRNA populations to characterize the expression of mitochondrial-encoded tRNAs and the identity of imported nuclear-encoded tRNAs. We also confirmed the utility of high-throughput sequencing methods for the detection of tRNA import by sequencing mitochondrial tRNA populations in a species (Solanum tuberosum) with known tRNA trafficking patterns. Mitochondrial tRNA sequencing in Silene revealed substantial shifts in the abundance of some nuclear-encoded tRNAs in conjunction with their recent history of mt-tRNA gene loss and surprising cases where tRNAs with anticodons still encoded in the mitochondrial genome also appeared to be imported. These data suggest that nuclear-encoded counterparts are likely replacing mitochondrial tRNAs even in systems with recent mitochondrial tRNA gene loss, and the redundant import of a nuclear-encoded tRNA may provide a mechanism for functional replacement between translation systems separated by billions of years of evolutionary divergence.

AbstractThe vaccination campaign against SARS-CoV-2 relies on the world-wide availability of effective vaccines, with a potential need of 20 billion vaccine doses to fully vaccinate the world population. To reach this goal, the manufacturing and logistic processes should be affordable to all countries, irrespectively of economical and climatic conditions.Outer membrane vesicles (OMVs) are bacterial-derived vesicles that can be engineered to incorporate heterologous antigens. Given the inherent adjuvanticity, such modified OMVs can be used as vaccine to induce potent immune responses against the associated protein. Here we show that OMVs engineered to incorporate peptides derived from the receptor binding motif (RBM) of the spike protein from SARS-CoV-2 elicit an effective immune response in immunized mice, resulting in the production of neutralizing antibodies. The immunity induced by the vaccine is sufficient to protect K18-hACE2 transgenic mice from intranasal challenge with SARS-CoV-2, preventing both virus replication in the lungs and the pathology associated with virus infection. Furthermore, we show that OMVs can be effectively decorated with RBM peptides derived from a different genetic variant of SARS-CoV-2, inducing a similarly potent neutralization activity in vaccinated mice. Altogether, given the convenience associated with ease of engineering, production and distribution, our results demonstrate that OMV-based SARS-CoV-2 vaccines can be a crucial addition to the vaccines currently available.
