In surgical practice, numerous sources of stress (stressors) are unpredictable, two examples being daily workload and postoperative complications. They may help to explain surgeon burnout, of which the prevalence (34 to 53%) has been the subject of many studies. Devimistat That said, even though assessments are legion, recommended solutions have been few and far between, especially insofar as by nature and training, surgeons are disinclined to interest themselves in burnout, which they are prone to consider as something experienced by "others". The objective of this attempt at clarification is to identify in the literature the strategies put forward in view of avoiding surgeon burnout, and to assess the impact of this phenomenon not only on the surgeon's professional and personal entourage, but also on patient safety. Prevention-based strategies, many of them focused on modifiable stressors, will be detailed.

Although eyelid melanomas represent less than 1% of eyelid neoplasms, they have the worst prognosis. Wide local excision (WLE) and Mohs micrographic surgery (MMS) are mainstay treatment options. We conducted a retrospective analysis to assess all-cause and cause-specific mortality rates in patients undergoing WLE or MMS for eyelid melanoma.

A retrospective analysis of Surveillance, Epidemiology, and End Results (SEER) registry was performed for eyelid melanoma treated with WLE or MMS. Cases were limited to American Joint Committee on Cancer (AJCC) stage T1 primary malignancies.

A total of 45 cases of WLE were identified along with 48 cases of MMS for eyelid melanoma. There was no significant difference between subgroups in age group, sex, race, ethnicity, marital status at diagnosis, AJCC N stage, AJCC M stage, melanoma histology, chemotherapy use, and radiotherapy use. Among the cohort, all tumors were unilateral. Kaplan-Meier analysis with log-rank demonstrated no significant difference between MMS antional purposes, MMS is a reasonable surgical approach.The authors present an anatomical study and clinical experience with radial forearm flap (RFF) and pronator quadratus muscle (PQM) application in the reconstruction of various body areas. The aim was to describe the anatomical placement and proportions of the PQM, the anatomical location of the major arterial branch of the radial artery supplying the PQM, and the application of this knowledge in clinical practice. The anatomical study was based upon an analysis of 13 fresh adult cadaver upper extremities, of which nine were female and four male; both arms from the same donors were used in four cases. The study of the PQM was performed using a dye-containing intraarterial injection, standard macro- and micro-preparation techniques, and chemical digestion. The data on the PQM size in males and females, thickness of the radial artery branch (the principal artery nourishing the muscle), and its position were analysed. The radial artery branch nourishing the PQM was identified in all cadaveric specimens of the anatomical study. In addition, 12 patients underwent reconstructions of soft and bony tissue defects using a RFF + PQM (pedicled or free flap). The radial artery branch perfusing the PQM was identified in all cases. The flap was used for the management of defects of the head (seven cases), arm (three cases) and lower leg (two cases). The harvest site healed well in all cases and, with the exception of one case in which a partial necrosis of the flap was observed, all flaps remained viable, which demonstrated the safety of the method.

Unlike palpable lumps, a large number of nonpalpable testicular lesions found incidentally at ultrasound in asymptomatic postpuberal males are either benign tumours or non-neoplastic lesions. The prevalence of malignancy, however, is appraised based on small case series. Dedicated studies report a large number of patients, and systematic review articles are lacking.

This systematic review is aimed to assess, from the analysis of the pooled data of the available literature, the incidence of benign tumours, malignant tumours, and non-neoplastic lesions, and to identify predictive characteristics for malignancy.

A systematic review of PubMed, Scopus, Google Scholar, Turning Research Into Practice (TRIP) database, and the Cochrane Library was conducted on January 6, 2022, according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Studies were retrieved reporting on adult asymptomatic men, with single, incidentally identified small testicular lesions, either fertiatients to reduce overtreatment.

Small testicular lesions are incidentally founded at ultrasound. It is not easy to distinguish a benign lesion from a malignant one. Results of this study are reporting a higher incidence of benign lesions with a diameter of <5 mm. More studies are needed to better understand the biology and the management strategy for small testicular lesions.

Is it possible to develop a quantitative method for detecting parental DNA contamination in conventional IVF using preimplantation genetic testing for aneuploidy (PGT-A)?

In this study, a quantification method was established for the parental contamination test (qPCT), which ensured more reliable results, and then verified its effectiveness for vitrified conventional IVF embryos. A total of 120 surplus vitrified blastocysts from patients who underwent prior routine IVF cycles were available for study.

The results of the prospective clinical study of qPCT-PGT-A showed that the maternal contamination rate was 0.83% (1/120) and that the risk of paternal contamination was negligible. The 24 frozen embryo transfer cycles resulted in 16 clinical pregnancies, including 13 live births, one late inevitable miscarriage and two ongoing pregnancies.

The risk of PGT in embryos with potential parental contamination is relatively low, and PGT-A is applicable for vitrified conventional IVF embryos.

The objective of this study was to estimate the economic impact of providing universal hepatitis C virus testing in commercially insured middle-aged persons who inject drugs in the U.S.

This study developed a dynamic 10-year economic model to project the clinical and economic outcomes associated with hepatitis C virus testing among middle-aged adult persons who inject drugs, from a payer's perspective. Costs related to hepatitis C virus testing, direct-acting antiviral, and liver-related outcomes between the (1) current hepatitis C virus testing rate (i.e., 8%) and (2) universal hepatitis C virus testing rate (i.e., 100%) were compared. Among patients testing positive, 21% of those without cirrhosis and 48% of those with cirrhosis were assumed to initiate direct-acting antivirals. Sensitivity analyses were performed to identify variables (e.g., direct-acting antiviral drug costs, hepatitis C virus testing costs, direct-acting antiviral treatment rate) influencing this study's conclusion.

The model predirals contributing the most to the spending. To promote universal hepatitis C virus testing among persons who inject drugs, decreasing direct-acting antiviral costs and sustainable funding streams for hepatitis C virus testing should be considered.

Nerve transfer (NT) surgery can improve function in people with cervical spinal cord injury (SCI). However, the impact of donor nerve deficits remains unclear. The purpose of this study was to quantify donor deficits experienced by individuals with cervical SCI following NT.

This prospective single-arm, comparative study included people with SCI undergoing upper extremity NTs. Myometry was used to assess muscle strength at baseline and follow-up. The Spinal Cord Independence Measure was used to measure the ability to perform activities of daily living.

Ten individuals underwent 20 NTs to restore elbow extension (donor, posterior deltoid; n= 2), hand opening (donor, supinator; n= 7), and hand closing (donor, brachialis; n= 11). Shoulder abduction strength decreased (-5.6% at early and-4.5% late follow-up) in the elbow extension NT. Wrist extension strength decreased at early (-46.9% ± 30.3) and increased by late (76.4% ± 154.0) follow-up in the hand opening NT. No statistically significant change in elbow flexion strength was noted in the hand closing NT. Spinal Cord Independence Measure scores did not change significantly between baseline and early postoperative follow-up; they improved at late follow-up.

Use of expendable donor nerves with redundant function to perform NT surgery has relatively little impact on strength or capacity to perform activities of daily living, even in the unique and highly vulnerable SCI population. Early, temporary loss in wrist extension strength can be seen after the supinator to posterior interosseous nerve transfer. This study offers quantitative data about possible diminution of donor function after NT, enabling hand surgeons to better counsel individuals contemplating upper extremity reconstruction.

Prognostic I.

Prognostic I.Phelan-McDermid syndrome (PMS) is a rare neurodevelopmental disease, caused by an autosomal dominant mutation due to the terminal deletion of 22q13, leading to a defect in the SHANK3 protein. We present the clinical case of a 12-year-old patient with this syndrome, who underwent three interventions that required general anesthesia. In none of them did she present intraoperative or postoperative complications.

SARS-CoV2 infection causes high morbidity and mortality in lung transplant (LT) recipients. Vaccination with messenger RNA vaccines has been shown to play a key role in controlling the severity of infection in the general population. The aim of our study is to analyze whether vaccination with 2 doses of SARS-Cov2 provides immunity in LT recipients.

Retrospective descriptive and analytical study of LT recipients vaccinated with 2 doses of SARS-CoV2. We analyzed the vaccine received, if they had COVID-19, antibody levels (antispike and antinucleoprotein), anticalcineurin levels, infections in the last year, and presence of neoplasias.

The most commonly administered vaccine was from Moderna, with 27% of patients showing immunity with a median antibody levels of 4.81 binding antibody units/mL, far from the values considered protective (> 34 binding antibody units/mL). Thirteen patients were infected with SARS-CoV2, 7 post vaccination (5 of them were antispike-positive). No relationship was demonstrated between generation of immunity and age and level of immunosuppression.

Vaccination against SARS-CoV2 in LT recipients generates limited and ineffective immunity with only 2 doses.
