Utility of TTMV-HPV DNA in resolving indeterminate findings during oropharyngeal cancer surveillance.

OBJECTIVES: Clinical and imaging examinations frequently have indeterminate results during cancer surveillance, which can lead to overtreatment and cause psychological and financial harm to the patient. This study addresses the critical need to enhance diagnostic precision and decision-making in the management of HPV-associated oropharyngeal cancer. This study evaluated the utility of tumor tissue-modified viral (TTMV)-HPV DNA to resolve indeterminate disease status following definitive treatment for HPV-associated oropharyngeal cancer. MATERIALS AND METHODS: In this retrospective cohort, patients treated for HPV-associated oropharyngeal cancer at eight U.S. institutions and who received one or more TTMV-HPV DNA tests during post-treatment surveillance between February 2020 and January 2022 were included. RESULTS: Among 543 patients, 210 patients (38.7%; 210/543) experienced one or more clinically indeterminate findings (CIFs) during surveillance, with 503 CIFs recorded. Of those patients with an "indeterminate" disease status at a point during surveillance, 79 were associated with contemporaneous TTMV-HPV DNA testing. TTMV-HPV DNA testing demonstrated high accuracy (97.5%; 77/79) in correctly determining recurrence status. Patients whose disease status was "indeterminate" at the time of a positive TTMV-HPV DNA test were clinically confirmed to recur faster than those whose disease status was "no evidence of disease." Only 3% of patients (17/543) experienced indeterminate TTMV-HPV DNA tests during surveillance. Discordance between TTMV-HPV DNA tests and clinical results was minimal, with only 0.6% (3/543) of patients showing positive tests without recurrence. CONCLUSION: Our findings support the utility of circulating TTMV-HPV DNA in resolving indeterminate disease status and informing the subsequent clinical course.

Anesthesiologist-directed care for elective gastrointestinal endoscopy: results of an Italian multicentric prospective observational study.

BACKGROUND: Sedation, ranging from minimal, moderate and deep sedation to general anesthesia, improves patient comfort and procedure quality in gastrointestinal endoscopy (GIE). There are currently no comprehensive recommendations on sedation practice in diagnostic and therapeutic GIE. We aimed to investigate real-life sedation practice in elective GIE. METHODS: We performed a multicentric observational study across 14 Endoscopy Units in Italy. We recorded consecutive data on all diagnostic procedures performed with Anesthesiologist-directed care (ADC) and all therapeutic procedures performed with ADC or non-Anesthesiologist sedation (NAS) over a three-month period. RESULTS: Dedicated ADC is available five days/week in 28.6% (4/14), four days/week in 21.5% (3/14), three days/week in 35.7% (5/14), two days/week in 7.1% (1/14) and one day/week in 7.1% (1/14) of participating Centers. ADC use for elective diagnostic GIE varied from 18.2% to 75.1% of the total number of procedures performed with ADC among different Centers. ADC use for elective therapeutic GIE varied from 10.8% to 98.9% of the total number of elective therapeutic procedures performed among different Centers. CONCLUSIONS: Our study highlights the lack of standardization and consequent great variability in sedation practice for elective GIE, with ADC being potentially overused for diagnostic procedures and underused for complex therapeutic procedures. A collaborative effort involving Endoscopists, Anesthesiologist and Institutions is needed to optimize sedation practice in GIE.

Evaluating human papillomavirus testing, prevalence, and association with prognosis in head and neck squamous cell carcinoma by subsite: A national cancer database study.

PURPOSE: To compare human papillomavirus (HPV) testing, prevalence, and association with prognosis between head and neck squamous cell carcinoma (HNSCC) subsites. MATERIALS AND METHODS: This study utilized the National Cancer Database (NCDB) to identify patients diagnosed with HNSCC between 2010 and 2017. Rates of HPV testing, HPV-positivity, and changes in these rates over time were measured by subsite. The impact of HPV-positivity on overall survival across six head and neck subsites was assessed using multivariable-adjusted Cox proportional hazards analysis. RESULTS: A total of 121,550 patients were included. Of this cohort, 87,575 (72.1%) were tested for HPV, with the oropharynx (55,049/64,158; 85.8%) displaying the highest rates of testing and the sinonasal tract (1519/2853; 53.2%) displaying the lowest testing rates. Of the 86,136 with a definitive result, 46,878 (54.4%) were HPV-positive, with the oropharynx (40,313/54,205; 74.4%) displaying the highest rates of HPV-positivity and the oral cavity (1818/11,505; 15.8%) displaying the lowest. HPV-positive malignancy was associated with significantly improved adjusted overall survival in the oropharynx (HR = 0.42 [95% CI: 0.43-0.47]), oral cavity (HR = 0.86 [95% CI: 0.79-0.95]), sinonasal tract (HR = 0.63 [95% CI: 0.48-0.83]), larynx (HR = 0.78 [95% CI: 0.71-0.87]), and hypopharynx (HR = 0.56 [95% CI: 0.48-0.66]), but not the nasopharynx (HR = 0.93 [95% CI: 0.77-1.14]). CONCLUSION: HPV testing rates were significantly lower in non-oropharyngeal subsites. This is relevant as HPV-associated disease displayed significantly improved overall survival in both the oropharynx and four of five non-oropharyngeal subsites. While validation with prospective studies is necessary, these findings may warrant HPV testing in all HNSCC subsites.

Impact of NNLO QED corrections on lepton-proton scattering at MUSE.

We present the complete next-to-next-to-leading order (NNLO) pure pointlike QED corrections to lepton-proton scattering, including three-photon-exchange contributions, and investigate their impact in the case of the MUSE experiment. These corrections are computed with no approximation regarding the energy of the emitted photons and taking into account lepton-mass effects. We contrast the NNLO QED corrections to known next-to-leading order corrections, where we include the elastic two-photon exchange (TPE) through a simple hadronic model calculation with a dipole ansatz for the proton electromagnetic form factors. We show that, in the low-momentum-transfer region accessed by the MUSE experiment, the improvement due to more sophisticated treatments of the TPE, including inelastic TPE, is of similar if not smaller size than some of the NNLO QED corrections. Hence, the latter have to be included in a precision determination of the low-energy proton structure from scattering data, in particular for electron-proton scattering. For muon-proton scattering, the NNLO QED corrections are considerably smaller.

Factors influencing autumn-winter movements of midcontinent Mallards and consequences for harvest and habitat management.

Annual phenology and distributions of migratory wildlife have been noticeably influenced by climate change, leading to concerns about sustainable populations. Recent studies exploring conditions influencing autumn migration departure have provided conflicting insights regarding factors influencing the movements of Mallards (Anas platyrhynchos), a popular game species. We determined factors affecting timing and magnitude of long-distance movements of 97 juvenile Mallards during autumn-winter across the midcontinent of North America marked with implanted transmitters in North and South Dakota, 2018-2019. Factors influencing variation in movement timing, along with direction and magnitudes, depended on type of movement (i.e., regional [25-310 km], initial migration, or subsequent migration movements [>310 km]). Photoperiod influenced probability of initiating all movements, although the effect was most influential for regional movements. Minimum temperature most influenced initial migration events (probability of movement increased 29% for each 1°C decrease); favorable winds also increased likelihood of initial migration events. Probability of subsequent migration events increased 80% for each 1 cm increase in depth of snow. Subsequent migration movements also were 2.0 times more likely to occur on weekend days, indicating disturbance from humans may influence movements. Migration distances increased 166 km for each 1°C reduction in minimum temperature. We also observed markedly different autumn-winter distributions of marked birds between years. Median locations during autumn-winter 2018-2019 were ~250 km farther north and ~300 km farther west during mid-December-January compared to the same time in 2019-2020. Concurrently, harvest rates for marked females and males were 10% and 26% during autumn-winter 2018-2019 and 26% and 31% during autumn-winter 2019-2020. Climate-related changes may result in increasingly variable autumn-winter distributions, with implications for wildlife recreationalists, conservation planners, and harvest managers.

Performance of Liquid Biopsy for Diagnosis and Surveillance of Human Papillomavirus-Associated Oropharyngeal Cancer.

Importance: There is growing interest in the use of circulating plasma tumor human papillomavirus (HPV) DNA for diagnosis and surveillance of patients with HPV-associated oropharyngeal squamous cell carcinoma (OPSCC). Recent advances in the assays, combining the identification of circulating HPV tumor DNA and tumor DNA fragment analysis (tumor tissue-modified viral [TTMV]-HPV DNA), have been shown to be highly accurate. However, use of these newer techniques has been limited to small cohort studies and clinical trials. Objective: To establish the clinical efficacy of plasma TTMV-HPV DNA testing in the diagnosis and surveillance of HPV-associated OPSCC in a contemporary clinical setting. Design, Setting, and Participants: This retrospective observational cohort study included patients with OPSCC who underwent TTMV-HPV DNA testing between April 2020 and September 2022 during the course of routine clinical care. For the diagnosis cohort, patients with at least 1 TTMV-HPV DNA measurement prior to initiation of primary therapy were included. Patients were included in the surveillance cohort if they had at least 1 TTMV-HPV DNA test performed after completion of definitive or salvage therapy. Main Outcomes and Measures: Per-test performance metrics, including sensitivity, specificity, positive predictive value, and negative predictive value, for TTMV-HPV DNA testing. Results: Of 399 patients included in the analysis, 163 were in the diagnostic cohort (median [IQR] age, 63 [56-68.5] years; 142 [87.1%] male), and 290 were in the surveillance cohort (median [IQR] age, 63 [57-70] years; 237 [81.7%] male). Of the 163 patients in the diagnostic cohort, 152 (93.3%) had HPV-associated OPSCC while 11 (6.7%) had HPV-negative OPSCC. The TTMV-HPV DNA sensitivity in pretreatment diagnosis was 91.5% (95% CI, 85.8%-95.4% [139 of 152 tests]), and the specificity was 100% (95% CI, 71.5%-100% [11 of 11 tests]). In the surveillance cohort, 591 tests conducted in 290 patients were evaluated. A total of 23 patients had molecularly confirmed pathologic recurrences. The TTMV-HPV DNA test demonstrated sensitivity of 88.4% (95% CI, 74.9%-96.1% [38 of 43 tests]) and specificity of 100% (95% CI, 99.3%-100% [548 of 548 tests]) in detecting the recurrences. Positive predictive value was 100% (95% CI, 90.7%-100% [38 of 38 tests]), and negative predictive value was 99.1% (95% CI, 97.9%-99.7% [548 of 553 tests]). The median (range) lead time from positive TTMV-HPV DNA test to pathologic confirmation was 47 (0-507) days. Conclusions and Relevance: This cohort study demonstrated that when evaluated in a clinical setting, the TTMV-HPV DNA assay demonstrated 100% specificity in both diagnosis and surveillance. However, the sensitivity was 91.5% for the diagnosis cohort and 88.4% for the surveillance cohort, signifying that nearly 1 in 10 negative tests among patients with HPV-associated OPSCC was a false negative. Additional research is required to validate the assay's performance and, if validated, then further research into the implementation of this assay into standard clinical practice guidelines will be required.

Neutrophil-to-lymphocyte ratio as a predictor of surgical outcomes in head and neck cancer.

BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR) is a biomarker of systemic inflammation that is associated with adverse oncologic and surgical outcomes. We investigated the use of NLR as a prognostic indicator of complications of head and neck cancer (HNC) surgeries. METHODS: We conducted a retrospective study of 11 187 Veterans who underwent HNC surgery between 2000 and 2020. We calculated preoperative NLR values and fit logistic regression models adjusting for potential confounding factors, comparing high-NLR patients to low-NLR patients. RESULTS: The cohort had a median age of 63 and was 98% men. High-NLR patients had increased odds of 30-day mortality (p < 0.001), having 1+ perioperative complications (p < 0.001), sepsis (p = 0.03), failure to wean from mechanical ventilation (p = 0.04), pneumonia (p < 0.001), and pulmonary embolism (p = 0.02) compared with low-NLR patients. CONCLUSION: NLR was a robust, independent predictor of 30-day mortality, having 1+ surgical complications, sepsis, failure to wean from mechanical ventilation, pneumonia, and pulmonary embolism.

COVID, the Gut, and Nutritional Implications.

Purpose of Review: The purpose of this review is to provide an overview of the current literature, recommendations, and practice guidelines on the nutritional management of and implications associated with COVID-19 infection. Recent Findings: Particular attention should be paid to the screening, prevention, and treatment of malnutrition in critically ill individuals with COVID-19 infection given the significant risk for complications and poor outcomes. Extrapolation of existing literature for the nutritional support in the critically ill patient has demonstrated early enteral nutrition is safe and well-tolerated in patients with severe COVID-19 infection. Summary: Futures studies should focus on the long-term nutritional outcomes for patients who have suffered COVID-19 infection, nutritional outcomes/recommendations for special populations with COVID-19, nutritional outcomes based on the current recommendations and guidelines for nutrition therapy, and the role for micronutrient supplementation in COVID-19 infection.

Prophylactic feeding tube placement for squamous cell carcinoma of the head and neck.

BACKGROUND: Percutaneous endoscopic gastronomy (PEG) tubes are commonly used to administer enteral nutrition during head and neck cancer (HNC) treatment. However, the benefits of placing a prophylactic feeding tube (PFT; prior to radiotherapy [RT]) or reactive feeding tube (RFT, after RT initiation) are unclear. We sought to compare survival, body mass trends, and hospitalization rates between strategies. METHODS: We conducted a retrospective cohort study of 11,473 Veterans with stages III-IVC HNC treated with chemoradiotherapy. Patients with PEG tube placement within 30 days prior to treatment initiation (PFT) were compared to all other patients (non-PFT) or patients with PEG tube placement within 3 months after treatment initiation placement (RFT). We compared survival, longitudinal body mass changes, and hospitalization rates for PFT versus non-PFT or RFT patients in propensity score (PS)-matched Cox regression models. RESULTS: 3,186 (28 %) patients received PFT and 8,287 (72 %) were non-PFT, of which 1,874 (23 %) received RFT. After PS-matching, there were no significant differences in overall survival (HR 0.97, 95 % CI 0.92-1.02), HNC-specific survival (HR 0.98, 95 % CI 0.92-1.09), change in BMI (p = 0.24), or hospitalization rates between PFT and non-PFT groups. Significant differences in hospitalization rates between PFT and RFT groups persisted after PS-matching (-0.11 hospitalizations/month), but no differences were found for other outcomes. CONCLUSION: Timing of PEG tube placement in Veterans with HNC was not associated with any significant survival or body mass advantage. However, patients who received PFT had a lower hospitalization rate than those who received RFT.

Degenerative and inflammatory musculoskeletal disorders: updates and hot topics in diagnostic and interventional imaging.

OBJECTIVE: The purpose of this review is to present the latest innovations and current topics in musculoskeletal diagnosis and interventional imaging, with a focus on degenerative and inflammatory diseases. MATERIALS AND METHODS: In this study, the search was conducted through the online databases PubMed and Google Scholar, including articles published in English in the past 15 years, in order to find existing studies, clinical cases, and reviews on the latest innovations and current topics in degenerative and inflammatory musculoskeletal pathologies. RESULTS: Imaging plays a pivotal role in the diagnosis and treatment of MSK degenerative and inflammatory disease. In the last few years continuous innovations and technological advances have allowed new clinical applications in the management of MSK disorder. Advanced magnetic resonance techniques, the introduction of fusion imaging techniques and new approaches to infiltrative medicine are revolutionizing the clinical and therapeutic approach to degenerative and inflammatory pathologies. Artificial intelligence also increasingly seeks to be applied in all fields of medicine and radiology with increasingly promising results. CONCLUSIONS: Imaging modalities undergo continuous innovations and revolutions due to technological advances, with direct repercussions on clinical applications and new therapeutic potential through interventional radiology techniques. In recent years, there have been particular innovations in the context of musculoskeletal imaging of degenerative and inflammatory diseases, both for diagnosis and intervention.

The Sinai Robotic Surgery Trial in HPV-related oropharyngeal squamous cell carcinoma (SIRS 2.0 trial) - study protocol for a phase II non-randomized non-inferiority trial.

Background: Human papillomavirus associated oropharyngeal squamous cell carcinoma (HPVOPSCC) usually affects a younger patient population. As such, the risk for long term toxicity associated with therapy is an important consideration. Multiple trials focused on de-escalation of therapy to preserve survival outcomes while minimizing treatment toxicity are currently in progress, however the question of which patients are ideal candidates for de-escalation remains unanswered. Circulating tumor DNA (cfHPVDNA) has emerged as a means of monitoring disease in patients with HPVOPSCC. Undetectable postoperative cfHPVDNA levels portend a better prognosis and by extension, may identify ideal candidates for de-escalation therapy. We propose an overview and rationale for a new institutional clinical trial protocol focusing on the use of cfHPVDNA to risk stratify patients for adjuvant therapy. We hypothesize that many surgical patients currently receiving radiation therapy may be clinically observed without adjuvant therapy. Methods: Patients with measurable cfHPVDNA and clinically resectable HPVOPSCC will undergo TORS resection of tumors and neck dissection. Patients with undetectable cfHPVDNA at 3 weeks post-op will be allocated to low or high-risk treatment protocol groups. The low risk group consists of patients with <4 positive lymph nodes, ≤2 mm extranodal extension (ENE), and perineural invasion (PNI) or lymphovascular invasion (LVI) alone. The high-risk group is made up of patients with ≥4 positive lymph nodes, gross ENE, positive margins, N2c disease and/or the combination of both PNI and LVI. The low-risk group will be allocated to an observation arm, while the high-risk group will receive 46 Gy of adjuvant radiotherapy and weekly cisplatin therapy. The primary outcome of interest is 2-year disease recurrence with secondary outcomes of 2-year disease free survival, locoregional control, overall survival, and quality of life measures. A sample of 126 patients in the low-risk group and 73 patients in the high-risk group will be required to evaluate non-inferiority to the standard of care. Discussion: This study will provide much needed recurrence and survival data for patients that undergo primary TORS followed by observation or de-escalated adjuvant therapy. Additionally, it will help delineate the role of cfHPVDNA in the risk stratification of patients that undergo treatment de-intensification.

Sex-Related Differences in Outcomes for Oropharyngeal Squamous Cell Carcinoma by HPV Status.

Background: Overall survival for HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) has differed by sex, but little is known regarding cancer-specific outcomes. We assessed the independent association of sex with cancer-specific survival in patients with HPV-associated oropharyngeal squamous cell carcinoma (OPSCC). Methods: We identified 14,183 patients from the Surveillance, Epidemiology, and End Results (SEER) program with OPSCC and tumor HPV status. We used Kaplan-Meier methods to compare overall survival (OS) and OPSCC-specific survival (HNCSS) by patient sex and by tumor HPV status. We then separately fit multivariable survival and competing risk models evaluating the association of sex on these outcomes by tumor HPV status and stratified by the use of guideline-concordant OPSCC treatment. Results: A total of 10,210 persons with HPV-positive tumors (72.0%) and 3,973 with HPV-negative tumors (28.0%) were identified. A larger proportion of women had HPV-negative tumors (24.0%) versus HPV-positive tumors (13.2%; p < 0.001). Women with HPV-positive tumors were less likely to receive guideline-concordant treatment compared to men. In unadjusted survival analyses, women did not differ in OS or HNCSS compared to men for HPV-positive tumors but had worse OS and HNCSS for HPV-negative tumors. After adjustment, men and women with HPV-positive OPSCC did not differ in OS or HNCSS. However, women with HPV-negative tumors faced worse overall survival (hazard ratio (HR) 1.15, 95% CI 1.02-1.29) that persisted even after stratifying for stage-appropriate treatment (HR 1.28, 95% CI 1.11-1.47). Conclusions: Women with HPV-positive OPSCC had similar survival outcomes compared to men, but those with HPV-negative tumors have worse overall and cancer-specific survival.

Impact of preoperative and intraoperative management on outcomes in osteoradionecrosis requiring free flap reconstruction.

BACKGROUND: Perioperative management of advanced osteoradionecrosis of the head and neck requiring free flap (FF) reconstruction varies. Our objectives included assessment of practice patterns and outcomes. METHODS: Multi-institutional, retrospective review of FF reconstruction for head and neck osteoradionecrosis (n = 260). RESULTS: Administration of preoperative antibiotics did not correlate with reduction in postoperative complications. Preoperative alcohol use correlated with higher rates of hardware exposure (p = 0.03) and 30-day readmission (p = 0.04). Patients with FF compromise had higher TSH (p = 0.04) and lower albumin levels (p = 0.005). Prealbumin levels were lower in patients who required neck washouts (p = 0.02) or a second FF (p = 0.03). TSH levels were higher in patients undergoing postoperative debridement (p = 0.03) or local flap procedures (p = 0.04). CONCLUSION: Malnutrition, hypothyroidism, and substance abuse correlated with a higher incidence of postoperative wound complications in patients undergoing FF reconstruction for advanced osteoradionecrosis. Preoperative antibiotics use did not correlate with a reduction in postoperative wound complications.

Metastatic endo and perineural involvement of the ulnar nerve from malignant melanoma: ultrasound (US) and magnetic resonance imaging (MRI) findings.

Malignant melanoma metastases occur in about 15% of patients. The most common localizations are lymph nodes, lungs, pancreas, bones. The central nervous system and the perineural region are rarely affected. In case of distant metastases, the survival rate is lower (about 25%). Involvement of peripheral nerve metastases from melanoma is reported in the literature just in one case. We report the ultrasound (US) integrated with Color-Doppler Ultrasound (CDU), elastosonography, and magnetic resonance imaging (MRI) findings of a rare case of metastatic endo- and perineural involvement of the ulnar nerve from cutaneous melanoma. Our purpose is to increase the clinicians' and radiologists' awareness on the possibility of metastatic spread to the peripheral nervous system and improve the differential diagnosis with other peripheral nerve sheath tumors.

Systematic review with meta-analysis: risk factors for Barrett's oesophagus in individuals with gastro-oesophageal reflux symptoms.

BACKGROUND: Gastro-oesophageal reflux is considered the main risk factor for Barrett's oesophagus. The role of other potential risk factors for the development of Barrett's oesophagus in patients with gastro-oesophageal reflux symptoms is controversial. AIMS: To perform a systematic review and meta-analysis examining risk factors in development of Barrett's oesophagus. METHODS: Medline, Embase and Embase Classic were searched (until December 2020) to identify cross-sectional studies reporting prevalence of Barrett's oesophagus based on presence of one or more proposed risk factors in individuals with gastro-oesophageal reflux symptoms. Prevalence of Barrett's oesophagus was compared according to presence or absence of each risk factor in individuals with gastro-oesophageal reflux symptoms. RESULTS: Of 7164 citations evaluated, 13 studies reported prevalence of Barrett's oesophagus in 11 856 subjects. Pooled prevalence of histologically confirmed Barrett's oesophagus in individuals with gastro-oesophageal reflux symptoms in all studies was 7.0% (95% CI 4.8% to 9.6%). Prevalence was higher in subjects with hiatal hernia (OR 2.74; 95% CI 1.58 to 4.75) and in those who drank alcohol (OR 1.51; 95% CI 1.17 to 1.95). Other features including non-steroidal anti-inflammatory drugs and/or aspirin use (OR 1.19; 95% CI 1.00 to 1.42), smoking (OR 1.14; 95% CI 0.96 to 1.35) or obesity (OR 1.10; 95% CI 0.92 to 1.33) were not significantly associated with Barrett's oesophagus. CONCLUSIONS: The prevalence of Barrett's oesophagus in individuals with gastro-oesophageal reflux symptoms was higher in those who drank alcohol, although this association was modest. The strongest association found was between hiatal hernia and Barrett's oesophagus. Other potential risk factors assessed in this study did not appear to be associated with presence of Barrett's oesophagus among individuals with gastro-oesophageal symptoms.

Treatment of Helicobacter pylori infection: a clinical practice update.

Helicobacter pylori infection still represents a major health issue, especially in developing countries, with an estimate of 4 billion of infected subjects in 2015. The increase of antibiotic resistance has undermined the efficacy of standard triple therapy leading to more complex regimens. This review summarizes recommendations of international guidelines and reports the most recent evidence from meta-analyses and clinical trials on the treatment of Helicobacter pylori infection. The choice of H. pylori eradication regimen should be based on the local prevalence of clarithromycin resistance and the previous use of macrolides. Quadruple therapies (bismuth quadruple and concomitant) are the recommended regimens for the first-line treatment; a 14-day clarithromycin-containing triple therapy is suggested in areas with low prevalence of clarithromycin resistance and in patients without previous use of macrolides. Data on the efficacy of sequential therapy against clarithromycin resistant H. pylori strains are contradictory, and its use in the treatment of H. pylori infection is generally discouraged. Second-line treatments include levofloxacin-containing triple therapy and bismuth quadruple therapy. Probiotic supplementation should be used with the aim to reduce antibiotic-related adverse events. Recent evidence would support current guideline recommendations for the treatment of Helicobacter pylori infection.

Addressing the Disproportionate Impacts of the COVID-19 Pandemic on Sexual and Gender Minority Populations in the United States: Actions Toward Equity.

Sexual and gender minority (SGM) populations may be affected disproportionately by health emergencies such as the coronavirus disease 2019 (COVID-19) pandemic. Health professionals must take immediate steps to ensure equitable treatment of SGM populations. These steps are to (1) maintain and increase cultural responsiveness training and preparedness for SGM populations, (2) increase use of sexual orientation and gender identity measures in surveillance, (3) conduct research on the impacts of COVID-19 on SGM populations, and (4) include equity-focused initiatives in disaster preparedness plans. These actions toward equity would begin to allow for our current health system to care more appropriately for SGM populations.

F. Brunelli Ligamentoplasty as Treatment in Thumb Basal Joint Arthritis: Up to 9 Years Follow-up.

Thumb basal joint arthritis treatment with biological arthroplasty is a widely used procedure in hand surgery centers. The several described techniques are based on the use of different tendons of the wrist, implying frequently a tenoplasty around flexor carpi radialis or transosseous tunnels to stabilize the articulation. The authors have been using, for many years, the technique conceived by F. Brunelli that relies on the anchorage of the volar band of the abductor pollicis longus tendon to the first intermetacarpal ligament, to obtain a suspension arthroplasty. Technical details are discussed. Sixty-seven patients in Eaton-Littler stage 2 or 3 with >4 years follow-up after surgery were evaluated. Each patient expressed a subjective evaluation relating to pain, functionality, strength, esthetic aspect, and general satisfaction. The following parameters have been considered as objective data: the angle of the first web space, the abduction and opposition of the first digit, the pinch, and the strength. X-rays were also performed to verify the distance between the scaphoid and the first metacarpal. In 84% of cases, a significant improvement was found in the considered parameters. Joint space was maintained in 76% of cases at radiologic follow-up. No patient needed surgical revision. The tenoplasty conceived by F. Brunelli presents several advantages, including the simple and reproducible execution, short surgical time, and comfortable postoperative course for the patient. After mid-term follow-up, authors believe this procedure is particularly respectful of the anatomy and physiology of the first ray and gives optimal results in most of the cases, but, in patients with severe subluxation of the 1st metacarpal (identifiable as Eaton-Littler stage 3), it is less reliable, because of the degeneration of the intermetacarpal ligament.
