Efficacy of Nortriptyline and Migraine Lifestyle Modifications in Vestibular Migraine Management.

OBJECTIVE: To evaluate the effectiveness of nortriptyline regimen and migraine dietary/lifestyle modifications on dizziness and stress levels in patients diagnosed with vestibular migraine (VM). METHODS: A total of 35 patients diagnosed with definite VM based on the International Classification of Headache Disorders were included in this intervention study. Patients self-selected to receive either nortriptyline regimen alone (10-40 mg daily with biweekly escalation) (group A, n = 17) or migraine dietary/lifestyle modifications alone (group B, n = 18). Main outcome measures were dizziness severity and stress level measured by the visual analog scale (VAS). RESULTS: At 4-week post-treatment, dizziness decreased from 6.0 ± 2.5 to 4.2 ± 3.4 (p = 0.069) in group A and from 8.7 ± 1.5 to 3.6 ± 3.0 (p < 0.001) in group B. VAS for stress changed from 5.5 ± 1.3 to 5.4 ± 2.9 (p = 0.93) and from 6.9 ± 3.2 to 5.0 ± 2.7 (p = 0.025) in groups A and B, respectively. The δ values of the VAS score for dizziness were 1.8 ± 3.7 and 5.1 ± 3.1 and the δ values of the VAS score for stress were 0.06 ± 2.9 and 1.9 ± 3.3 in groups A and B, respectively. Quality of life (QOL) improved in 88% patients in group A and 94% patients in group B. CONCLUSIONS: Nortriptyline, at a maximum dose of 40 mg, effectively alleviates patient symptoms, while a migraine diet and lifestyle modifications notably reduce vertiginous symptoms and stress levels in VM patients in 4 weeks. Both interventions are equally effective in ameliorating the QOL of patients. The ideal treatment for patients would likely need to include both medication and diet/lifestyle changes.

Retrorectus Ventral Hernia Repair Utilizing T-line Hernia Mesh: Technical Descriptions.

The T-line hernia mesh is a synthetic, polypropylene mesh with mesh suture extensions designed to prevent anchor point failure by evenly distributing tension across the soft tissue. Previous studies have demonstrated the success of onlay ventral hernia repair with T-line hernia mesh, but retrorectus applications of the mesh have not yet been characterized. This technique article illustrates technical descriptions and clinical applications of the T-line hernia mesh in the retrorectus plane.

The impact of bleeding on outcomes following lung transplantation: a retrospective analysis using the universal definition of perioperative bleeding.

BACKGROUND: Lung transplantation (LT) represents a high-risk procedure for end-stage lung diseases. This study describes the outcomes of patients undergoing LT that require massive transfusions as defined by the universal definition of perioperative bleeding (UDPB). METHODS: Adult patients who underwent bilateral LT at a single academic center were surveyed retrospectively. Patients were grouped by insignificant, mild, or moderate perioperative bleeding (insignificant-to-moderate bleeders) and severe or massive perioperative bleeding (severe-to-massive bleeders) based on the UDPB classification. Outcomes included 1-year survival and primary graft dysfunction (PGD) of grade 3 at 72 h postoperatively. Multivariable models were adjusted for recipient age, sex, body mass index (BMI), Lung allocation score (LAS), preoperative hemoglobin (Hb), preoperative extracorporeal membrane oxygenation (ECMO) status, transplant number, and donor status. An additional multivariable model was created to find preoperative and intraoperative predictors of severe-to-massive bleeding. A p-value less than 0.05 was selected for significance. RESULTS: A total of 528 patients were included, with 357 insignificant-to-moderate bleeders and 171 severe-to-massive bleeders. Postoperatively, severe-to-massive bleeders had higher rates of PGD grade 3 at 72 h, longer hospital stays, higher mortality rates at 30 days and one year, and were less likely to achieve textbook outcomes for LT. They also required postoperative ECMO, reintubation for over 48 h, tracheostomy, reintervention, and dialysis at higher rates. In the multivariate analysis, severe-to-massive bleeding was significantly associated with adverse outcomes after adjusting for recipient and donor factors, with an odds ratio of 7.73 (95% CI: 4.27-14.4, p < 0.001) for PGD3 at 72 h, 4.30 (95% CI: 2.30-8.12, p < 0.001) for 1-year mortality, and 1.75 (95% CI: 1.52-2.01, p < 0.001) for longer hospital stays. Additionally, severe-to-massive bleeders were less likely to achieve textbook outcomes, with an odds ratio of 0.07 (95% CI: 0.02-0.16, p < 0.001). Preoperative and intraoperative predictors of severe/massive bleeding were identified, with White patients having lower odds compared to Black patients (OR: 041, 95% CI: 0.22-0.80, p = 0.008). Each 1-unit increase in BMI decreased the odds of bleeding (OR: 0.89, 95% CI: 0.83-0.95, p < 0.001), while each 1-unit increase in MPAP increased the odds of bleeding (OR: 1.04, 95% CI: 1.02-1.06, p < 0.001). First-time transplant recipients had lower risk (OR: 0.16, 95% CI: 0.06-0.36, p < 0.001), whereas those with DCD donors had a higher risk of severe-to-massive bleeding (OR: 3.09, 95% CI: 1.63-5.87, p = 0.001). CONCLUSION: These results suggest that patients at high risk of massive bleeding require higher utilization of hospital resources. Understanding their outcomes is important, as it may inform future decisions to transplant comparable patients.

Google Trends Analysis of Otologic Symptom Searches Following COVID-19.

Introduction: COVID-19 infection was accompanied by otologic symptoms, a pattern that was captured early by Google Trends. The objective of this study is to investigate searches for otologic symptoms and identify correlations with the pandemic onset. Materials and Methods: Search interest for otologic symptoms was gathered using Google Trends from two years before and two years following the pandemic start date. A two-tailed Mann-Whitney U test was used to identify significant changes and effect size. Results: In total, search interest for 14 terms was collected, with significant changes identified in 11. Six terms showed increased search interest, with the most significant rises observed for headache (r=0.589, p<0.001), dizziness (r=0.554, p<0.001), and tinnitus (r=0.410, p<0.001). Search interest decreased for five terms, with the most notable declines found in searches for migraine headache (r=0.35, p<0.001) and phonophobia (r=0.22, p=0.002). No significant changes were seen in ear pressure (p=0.142), neck pain (p=0.935), and sudden hearing loss (p=0.863) searches. Conclusion: COVID-19 infection is often accompanied otologic symptoms and holds a diagnostic role. Fluctuating search interest may be attributed to a true increase in cases, media trends, or people's desires to stay informed. Google Trends robustly captured trends in search interest and presented itself as a valuable epidemiological tool.

Online ratings and narrative comments of American Head and Neck Society surgeons.

BACKGROUND: We analyzed online rating scores and comments of head and neck surgeons to understand factors that contribute to higher ratings. METHODS: Numerical ratings and comments for American Head and Neck Society physicians were extracted from Healthgrades, Vitals, RateMDs, and Yelp, with narrative comments categorized based on content. Physician practice location, education, and residency training were also compiled. RESULTS: Patient ratings were significantly higher with supportive staff and affable physician demeanor but showed significant drops with longer wait times and difficulties scheduling appointments or follow-ups. Physician education and postgraduate training did not significantly affect ratings. CONCLUSION: Online ratings and comments correlated to modifiable factors in clinical practice and may be informative in understanding patient needs.

T-line Hernia Mesh Repairs of Large Umbilical Hernias: Technique and Short-term Outcomes.

Background: The T-line hernia mesh is a synthetic, polypropylene mesh specifically designed to prevent anchor point failure by evenly distributing tension through mesh suture extensions. This case series illustrates the first clinical application of the T-line mesh for umbilical hernia repair (UHR). Methods: This study is a retrospective, consecutive cases series of all adult patients presenting to a single surgeon with symptomatic umbilical hernia requiring surgical repair using the T-line hernia mesh. Patient demographics, surgical details, and 30-day postoperative complications were collected. Descriptive statistics were computed in Microsoft Excel (Redmond, Va.). Results: Three patients presented for UHR. All three patients were obese with mean body mass index of 37.5 ±â€…6.6. Two patients were former smokers, and two had presented after hernia recurrence. The average defect size was 80.1 cm2 ± 94.0 cm2. Two patients had UHR with onlay mesh placement, whereas one had a transversus abdominus release followed by retrorectus mesh placement. The average mesh size was 192.3 cm2 ± 82.5 cm2. All three cases were classified as clean. There were no intraoperative complications. No patients experienced 30-day postoperative complications or recurrence. Conclusions: We present a case series of three patients presenting with large, symptomatic umbilical hernias who underwent UHR with T-line hernia mesh reinforcement without short term complications or hernia recurrence at last follow-up.

Evaluating the impact of work from home policies on Google search Trends related to ankle surgery during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic caused notable shifts in healthcare behavior, influenced by remote work policies. This study examines the impact of Work from Home (WFH) policies on public interest in ankle-related orthopaedic surgeries, utilizing Google search trends. Understanding these trends is crucial for healthcare providers, enabling them to adapt services and communication to evolving patient needs during challenging times. OBJECTIVE: To comprehend variations in search volume and trends for ankle-related queries due to WFH policies during the COVID-19 pandemic. METHODS: Ankle-related terms accessible to laypersons were analyzed using Google Trends data from March 2018 to March 2022 in the United States. Data were divided into pre-pandemic (March 2018-March 2020) and post-pandemic (March 2020-March 2022) periods. Weekly search interest data for 20 terms were analyzed using a Mann-Whitney U test. The study aimed to identify significant changes in search interest, providing insights into public information-seeking behavior concerning ankle surgeries. RESULTS: Among the 20 terms analyzed, 11 exhibited significant changes. Ankle arthritis and ankle bursitis showed increased interest, suggesting heightened concern during the pandemic. Conversely, post-pandemic interest decreased for terms 9 terms, including ankle pain and ankle tendonitis, indicating reduced worry. Moderate declines were noted for ankle gout, Achilles tendonitis, and heel bursitis, reflecting shifting patient priorities. Some terms, including ankle fracture and ankle arthroplasty, showed stable information-seeking behavior despite the pandemic. CONCLUSIONS: The study underscores the nuanced impact of WFH policies on public interest in ankle-related orthopaedic surgeries. Varied search trends highlight changing patient concerns. Healthcare providers can use these insights to tailor services effectively, meeting evolving patient needs and enhancing communication strategies.

Microsurgical Needle Retention Does Not Cause Pain or Neurovascular Injury in a Rat Model.

Approximately 20% of retained foreign bodies are surgical needles. Retained macro-needles may become symptomatic, but the effect of microsurgical needles is uncertain. We present the first animal model to simulate microsurgical needle retention. Given a lack of reported adverse outcomes associated with macro-needles and a smaller cutting area of microsurgical needles, we hypothesized that microsurgical needles in rats would not cause changes in health or neurovascular compromise. Methods: Male Sprague-Dawley rats (x̄ weight: 288.9 g) were implanted with a single, 9.0 needle (n = 8) or 8.0 needle (n = 8) orthogonal to the right femoral vessels and sutured in place. A control group (n = 8) underwent sham surgery. Weekly, a cumulative health score evaluating body weight, body condition score, physical appearance, and behavior for each rat was determined. Infrared thermography (°C, FLIR one) of each hindlimb and the difference was obtained on postoperative days 15, 30, 60, and 90. On day 90, animals were euthanatized, hindlimbs were imaged via fluoroscopy, and needles were explanted. Results: The mean, cumulative health score for all cohorts at each weekly timepoint was 0. The mean temperature difference was not significantly different on postoperative days 15 (P = 0.54), 30 (P = 0.97), 60 (P = 0.29), or 90 (P = 0.09). In seven of eight rats, 8.0 needles were recovered and visualized on fluoroscopy. In six of eight rats, 9.0 needles were recovered, but 0/8 needles were visualized on fluoroscopy. Conclusions: Microsurgical needle retention near neurovascular structures may be benign, and imaging for needles smaller than 8.0 may be futile. Further studies should explore microsurgical needle retention potentially through larger animal models.

Correlation Between Laterality of Hearing Loss and Migraine Features in Menière's Disease.

OBJECTIVES: The objective of this study is to understand whether the hearing loss laterality in Menière's disease (MD) correlates with migraine symptoms laterality such as headache, neck stiffness, and otalgia. METHODS: We performed a retrospective review of prospectively obtained data on patients presenting between September 2015 and October 2021 with definite or probable MD. A custom-designed, comprehensive questionnaire was used to identify patients' migraine-related symptoms. The clinical and audiometric data were used to diagnose patients with definite or probable MD using criteria set by the American Academy of Otolaryngology-Head and Neck Surgery. RESULTS: In total, 113 patients with definite or probable MD were included in the study. The mean age of the patients was 60 ± 15 years with no gender predominance (49.6% male and 50.4% female). A total of 57 (50%) patients were presented with headaches. Among the migraine headache cohort, headache and otalgia were on the same side as the MD ear affected by hearing loss. In addition, in patients who present with otalgia as the primary feature of headache, otalgia was more likely to be on the same side as the ear affected by the hearing loss. CONCLUSIONS: The high prevalence of migraine symptoms on the same side of the ear affected by MD among this cohort could suggest a shared pathophysiology in both MD and migraine, possibly involving migraine-related changes in both the cochlea and vestibule.

One hundred most-cited articles in head and neck surgery and analysis of female authorship.

BACKGROUND: While female head and neck surgeons have made significant contributions to the field, women's achievements in scientific communication have traditionally been underreported. METHODS: A search of high-impact journals in the field of head and neck surgery was performed in the Elsevier's Scopus database to identify the top 100 most-cited articles. RESULTS: The top 100 most-cited articles (during the span of 1953 and 2016) had the highest total number of citations between 2005 and 2009. Women accounted for 36% of first authors and 25% of corresponding authors. Change in the relative number of first female authors in these top 100 articles did not increase significantly between 1950 and 2019. CONCLUSION: The proportion of female first authors in head and neck surgery has not significantly increased over the past several decades, despite greater numbers of female trainees. Our findings support the need for additional research on female representation in head and neck surgery.

Online Patient Reviews of Breast Reconstruction: RealSelf Analysis.

RealSelf is an online community that hosts an expansive number of online reviews for cosmetic and reconstructive plastic surgery procedures. The purpose of this study is to analyze patient satisfaction with breast reconstruction procedures from RealSelf to determine factors contributing to a positive or negative patient experience. Methods: The breast reconstruction category from RealSelf.com was analyzed using a web crawler-based application built from Python and Selenium. Reviews were collected from May 2009 to November 2021. Information including RealSelf's inherent "worth it" ranking system, review text, the number of submitted photographs, and the number of readers who found the review helpful was captured. The content of the review was then independently reviewed by the authors and was categorized with key factors that determined positive or negative reviews. Results: A total of 3451 breast reconstruction reviews were collected. After the authors analyzed each review, 3225 (94.33%) were identified as positive reviews. The most common factors associated with positive reviews were physician demeanor (n = 2600, 31.7%), aesthetic outcome (n = 1955, 23.8%), or staff (n = 1543, 18.8%), while negative reviews were associated with unfavorable aesthetic outcome (n = 94, 28.9%), physician demeanor (n = 82, 25.2%), or postoperative complications (n = 75, 23.1%). Conclusions: Although there are surveys that analyze patient satisfaction for breast reconstruction, there has not been a study that analyzed a large online review database. Predominating factors in both positive and negative reviews were physician demeanor and aesthetic outcome.

Single-molecule Taq DNA polymerase dynamics.

Taq DNA polymerase functions at elevated temperatures with fast conformational dynamics-regimes previously inaccessible to mechanistic, single-molecule studies. Here, single-walled carbon nanotube transistors recorded the motions of Taq molecules processing matched or mismatched template-deoxynucleotide triphosphate pairs from 22° to 85°C. By using four enzyme orientations, the whole-enzyme closures of nucleotide incorporations were distinguished from more rapid, 20-µs closures of Taq's fingers domain testing complementarity and orientation. On average, one transient closure was observed for every nucleotide binding event; even complementary substrate pairs averaged five transient closures between each catalytic incorporation at 72°C. The rate and duration of the transient closures and the catalytic events had almost no temperature dependence, leaving all of Taq's temperature sensitivity to its rate-determining open state.

Pyrocinchonimides Conjugate to Amine Groups on Proteins via Imide Transfer.

Advances in bioconjugation, the ability to link biomolecules to each other, small molecules, surfaces, and more, can spur the development of advanced materials and therapeutics. We have discovered that pyrocinchonimide, the dimethylated analogue of maleimide, undergoes a surprising transformation with biomolecules. The reaction targets amines and involves an imide transfer, which has not been previously reported for bioconjugation purposes. Despite their similarity to maleimides, pyrocinchonimides do not react with free thiols. Though both lysine residues and the N-termini of proteins can receive the transferred imide, the reaction also exhibits a marked preference for certain amines that cannot solely be ascribed to solvent accessibility. This property is peculiar among amine-targeting reactions and can reduce combinatorial diversity when many available reactive amines are available, such as in the formation of antibody-drug conjugates. Unlike amides, the modification undergoes very slow reversion under high pH conditions. The reaction offers a thermodynamically controlled route to single or multiple modifications of proteins for a wide range of applications.
