ABSTRACT

BACKGROUND: To our knowledge, there is no useful and accurate prognostic biomarker or biomarkers for patients with oral squamous cell carcinoma (OSCC), a tumor with uncertain biological behavior, and unpredictable clinical progress. The purposes of this study were: a) to determine the expresión profile of Connexin 43, Bcl-2, Bax, E-cadherin, and Ki67 in patients with OSCC; b) identify the GJCA1 rs12197797 genotypic composition.

MATERIAL AND METHODS: A cross-sectional study using genomic DNA and biopsy samples extracted from the oral mucosa with/without OSCC, older than 18 years, both genders, attended at Facultad de Odontología, Universidad Nacional Córdoba. Immunostaining for Cx43, Bcl-2, Bax, E-cadherin, and Ki67 and genotyping GJA1 rs12197797 by RFLP were performed. Odds Ratio (95% CI), Spearman Coefficient were estimated. Mann-Whitney test was applied to analyze immunostaining between controls/cases (p <0.05 was set for statistical significance).

RESULTS: GG (mutant) was the most frequent genotype in patients with OSCC diagnosis (53.2%) in relation to CC “healthy” genotype (p=0.00487; OR=7.33; CI95% [1.1-54.7]). And, the allele G (mutant) had a presence in 75.5% of OSCC patients. However, no significant association was observed between alleles C/G and diagnosis (p=0.0565). The heterozygous genotype was the most frequent in the patients of both groups Cx43 and E-cadherin markers were lower in OSCCs in relation to controls. Ki67 and Bcl-2 immunolabeling were high on OSCC, and Bax immunomarker was diminished in OSCC.

CONCLUSIONS: We hypothesized that the oral epithelium losses Connexin 43 and E-cadherin in the membrane, which modifies cell differentiation. The Ki67 and Bcl2 overexpression would increase the cell density in the tissue, by promoting proliferation and decreasing apoptosis. And, this study shows evidence that patients who carry on allele G of GJA1rs12197797 could be at risk of developing OSCC.

ABSTRACT

This study aimed to develop a smartphone-based home workout program for shift-work nurses to increase their levels of exercise and examine its effects on health (sleep disturbance, fatigue, musculoskeletal problems, and resilience) and nursing performance. For this quasi-experimental study with a nonequivalent control group, 54 shift-work nurses were recruited from two general wards at a hospital in Korea and assigned to the intervention and control groups. Nurses in the intervention group were encouraged to exercise regularly using the home workout application for 18 weeks. For the first 12 weeks, text-message counseling and environmental improvement were carried out; only environmental improvement was implemented in the remaining 12-18 weeks. The control group did not receive any intervention. After excluding dropouts, the data of the final 25 participants in the intervention group and 24 participants in the control group were analyzed. Compared with the control group, the intervention group showed statistically significant improvements in physical and psychological health. Hospital organizations could adopt a smartphone-based home workout program to overcome obstacles to exercise, which could lead to positive health outcomes for shift-work nurses.

ABSTRACT

PURPOSE: The aim of this retrospective analysis was to investigate and evaluate differences in functional outcome and satisfaction of patients treated with a TOPS and patients using socket prosthesis after transfemoral amputation.

METHODS: This retrospective comprehensive analysis included patients from a single hospital, and was conducted between February 2017 and December 2018. Overall n = 139 patients with prosthesis were included and divided into two comparable groups (socket- and TOPS group). Incomplete data sets were excluded. This led to n = 36 participants for the socket- and n = 33 for the TOPS group. Functional outcome and satisfaction were evaluated by Patient Reported Outcome Measures (PROMs). The used PROMs were: Questionnaire for Persons with a Transfemoral Amputation (Q-TFA), EQ5D-5L, Satisfaction with Prosthesis Questionnaire (SAT-PRO), Prosthesis Mobility Questionnaire (PMQ 2.0) and Functional Independence Measure (FIM).

RESULTS: Significant results in favor of TOPS patients were identified for the EQ-5D 5L (p = 0.004), Q-TFA (p = 0.000), SAT-PRO (p = 0.000) and PMQ 2.0 (p = 0.000). For FIM, no statistical significance was found (p = 0.318).

CONCLUSION: In this study, transfemoral amputees treated with an osseointegrated prosthetic attachment (TOPS) showed significantly higher scores for mobility and satisfaction. This demonstrates the high potential of TOPS in the prosthetic treatment of patients with transfemoral amputation with regard to their functional abilities in daily life.

ABSTRACT

OBJECTIVE: This study aimed to investigate the effectiveness and safety of idarucizumab for periprocedural cardiac tamponade after catheter ablation of atrial fibrillation (AF) in patients treated with dabigatran.

METHODS: We retrospectively studied 28 patients who received catheter ablation of AF and developed periprocedural cardiac tamponade. Patients were divided into two groups: control group (14 cases) and the study group (14 cases). Patients in the control group were administered warfarin bridged with low molecular weight heparin, while patients in the study group were given dabigatran for anticoagulation. Heparin was used for anticoagulation during surgery in both groups. Patients with cardiac tamponade in control group was reversed with protamine and the ones in study group were given protamine and idarucizumab. In the two groups, operative time, time to resume anticoagulation, bleeding time, length of hospital stay, hemodynamic parameters, coagulation function parameters, number of patients undergoing thoracotomy for hemostasis, pericardiocentesis drainage volume, and pericardial drainage retention time were recorded.

RESULTS: There was no statistical difference in operative time and length of hospital stay between the two groups (p > 0.05); however, time to resume anticoagulation and bleeding time were significantly lower in the study group than in the control group, with a statistical difference (p < 0.05). After anticoagulation therapy, there was no apparent change and no statistical difference in the hemodynamic parameters and SaO₂ between the two groups (p > 0.05). The pericardial drainage volume retention time was significantly shorter in the study group than in the control group, with a statistical difference (p < 0.05).

CONCLUSION: Idarucizumab can rapidly and effectively reverse the anticoagulant effect of dabigatran in patients with AF who have periprocedural cardiac tamponade after catheter ablation.

ABSTRACT

BACKGROUND: Although bacillus Calmette-Guerin (BCG) is a standard treatment for high-risk non-muscle-invasive bladder cancer (NMIBC), a high rate of adverse events with a variety of grades remains a difficulty.

OBJECTIVE: In this randomized, prospective, multicenter study, we examined whether levofloxacin, given after each intravesical instillation of BCG, could improve its tolerance in patients with intermediate- to high-risk urothelial carcinoma of the bladder without compromising its efficacy.

DESIGN, SETTING, AND PARTICIPANTS: Overall, 106 Japanese patients (85 men and 21 women; age: median, 69.5 yr) with primary or recurrent NMIBC were randomized after transurethral resection to induce treatment with intravesical BCG plus levofloxacin (group 1) or BCG alone (group 2).

INTERVENTION: Patients who underwent intravesical instillation of BCG were randomized with or without levofloxacin administration.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Adverse events were assessed using the National Cancer Institute-Common Toxicity Criteria version 3.0. Cumulative incidence functions and Kaplan-Meier methods were applied to estimate survival outcomes.

RESULTS AND LIMITATIONS: There was no significant difference in baseline characteristics between the groups. The completion rate of group 1 (85.5%) was not significantly lower than that of group 2 (76.5%; p = 0.321). There was no significant difference in the completion rate of patients with pollakisuria, painful micturition, gross hematuria, fever elevation, and others between the groups. The incidence of adverse events in patients with high-grade pollakisuria (7.3% vs 25.4%, p = 0.041) and fever (0% vs 9.1%, p = 0.034) was significantly lower in group 1. The 5-yr progression-free and cancer-specific survival rates were significantly better in group 1.

CONCLUSIONS: Prophylactic levofloxacin administration may reduce the severity of adverse events and contribute to better outcomes from BCG intravesical therapy in patients with NMIBC.

PATIENT SUMMARY: Levofloxacin administration seems to be a safe and effective therapy for non-muscle-invasive bladder cancer patients treated with bacillus Calmette-Guerin intravesical therapy.

ABSTRACT

Post radical prostatectomy (RP) erectile dysfunction and incontinence impacts quality of life for patients. In an objective to hasten the recovery of these functional outcomes, human placental derived allografts laid on neurovascular bundles (NVB) have been investigated. These grafts include amniotic membranes (AM) chorionic membranes (CM) or umbilical cord (UC) allografts. A literature review performed using the MeSH terms “AMNION” OR “CHORION” OR “AMNIOTIC MEMBRANE” OR “UMBILICAL CORD” AND “PROSTATE CANCER” from no specified start date, to April 2022. 163 articles were retrieved, with 149 articles excluded. 14 articles were eligible and analysed. 5 articles were included in this review for an analysis on comparative outcomes. The average return to potency was statistically significant in the intervention groups. Positive surgical margin (PSM) rates showed a higher rate in the control groups. BCR was observed at a lower rate in the interventional group. This review reveals a benefit from human placental allograft’s ability to hasten post RP functional recovery, without impacting oncological control.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: This study aims to determine whether the use of preoperative transdermal scopolamine is associated with an increased risk of postoperative urinary retention in urogynecologic surgeries.

METHODS: This is a retrospective chart review study of women who underwent surgery between January 1, 2018, and December 31, 2020. Patients who received a scopolamine patch versus those who did not were compared using demographic and perioperative variables utilizing Pearson’s chi-squared test and t-test of Wilcoxon rank-sum. A logistic regression was performed to evaluate the effect of scopolamine on the patients’ postoperative voiding trial results, controlling for confounders. P-value < 0.05 was considered statistically significant.

RESULTS: A total of 449 women underwent a vaginal or laparoscopic hysterectomy, midurethral sling placement, uterosacral or sacrospinous ligament suspension, sacrocolpopexy, anterior/posterior colporrhaphy, or other urogynecologic surgeries with 109 (24.2%) having received transdermal scopolamine. A significantly higher number of women with preoperative scopolamine [n = 50 (45.9%)] failed their voiding trial compared to those without scopolamine [n = 100 (29.4%), p = 0.0016]. The adjusted model yielded an odds ratio of 1.75 (95% CI: 1.08-2.85) of a failed voiding trial in the scopolamine group. When comparing the odds of failing voiding trial by surgery type, those with a midurethral sling placed during surgery had an adjusted odds ratio of 3.12 (95% CI: 2.01-4.87), as compared to those without a midurethral sling.

CONCLUSIONS: Use of a transdermal scopolamine patch for nausea and vomiting prophylaxis is associated with increased risk of postoperative urinary retention across all urogynecologic surgeries.

ABSTRACT

We previously found an association of insulin resistance (IR) with plasma xanthine oxidoreductase (XOR) activity in a cross-sectional study. However, whether IR induces increased XOR activity has not been elucidated. This retrospective longitudinal observational study included 347 participants (173 males, 174 females) who underwent annual health examinations and were medication naïve. Homeostasis model assessment of IR (HOMA-IR) index, and physical and laboratory measurements were determined at the baseline. At baseline and 12-month follow-up examinations, plasma XOR activity was determined using our novel assay based on [¹³C₂,¹⁵N₂] xanthine and liquid chromatography/triple quadrupole mass spectrometry. Subjects with IR, defined as HOMA-IR index ≥ 1.7 (n = 92), exhibited significantly (p < 0.001) higher plasma XOR activity levels than those without IR (n = 255), with an increase in that activity seen in 180 (51.9%) after 12 months. Multivariable linear and logistic regression analyses showed that IR, but not BMI or waist circumference, at baseline was significantly associated with plasma XOR activity (β = 0.094, p = 0.033) and increased plasma XOR activity over the 12-month period (odds ratio, 1.986; 95% confidence interval, 1.048-3.761; p = 0.035), after adjustments for various clinical parameters, including plasma XOR activity at baseline. These results suggest that IR induces increased plasma XOR activity in a manner independent of adiposity.

ABSTRACT

PURPOSE: Petroclival meningioma (PM) is a challenging neuro oncology case and stereotactic radiosurgery (SRS) is proposed as one treatment option. This systematic review aimed to examine the role of SRS in treating PM cases.

METHODS: We constructed a systematic review using the PRISMA guidelines using peer-reviewed English literature until 16 February 2022 from EuroPMC and PubMed. We used the terms petroclival meningioma, clival meningioma, apex petrous meningioma, spheno petroclival meningioma, stereotactic radiosurgery, radiosurgery, CyberKnife, Gamma Knife, linear accelerator, LINAC, and radiotherapy.

RESULTS: 10 out of 266 studies were chosen for this systematic review, two of which are case reports. The study comprised 719 patients, 73.7% of whom were female (n = 530) and had a median age of 56.99 years (18-90 years). At the time of diagnosis, the median tumor volume was 6.07 cm³ (0.13-64.9 cm³). The tumors were frequently located near the petroclival junction (83.6%, n = 598). Following SRS, the median follow-up was 64.52 months (3-252 months). 46.5% of 719 PMs exhibited a decrease in tumor size. 46% and 7.5% showed no change and increase in tumor volume, respectively. At the last radiographic follow-up (7-21.2 years), tumor control with a median of 98.8% (85-100%). Complications occurred in 6% of patients, with hydrocephalus (2.2%) as the prevalent complication. The use of SRS as a primary treatment for petroclival cases was not associated with increased complication rate RR 0.62 (95% CI [0.11, 3.59], p = 0.59) but statistically correlated with clinical failure clinical failure RR 0.56 (95% CI [0.32, 0.98], p = 0.04).

CONCLUSIONS: We found a low number of complications following SRS intervention and has been effectively controlling tumor progression.
