ABSTRACT
PURPOSE: This study aimed to determine the occurrence of incidental obturator hernia and clinical risk factors of their appearance in patients undergoing totally extraperitoneal (TEP) inguinal hernioplasty. METHODS: Data were collected retrospectively from patients who underwent TEP inguinal hernioplasty between June 2020 and December 2022. RESULTS: A total of 251 patients were included in the study. Obturator hernias were found in 21 patients (8.4%). At admission, no patient presented clinical signs of an obturator hernia. There was a significant predominance of women in the obturator hernia compared to the non-obturator hernia group (28.6% vs. 10.9%, respectively, p=0.018). There was no correlation between age (p=0.479) and BMI (p=0.771) and the occurrence of obturator hernia. Additional obturator hernia repair within the TEP inguinal hernioplasty procedure did not influence the overall length of the surgery (60.86 minutes) compared to the standard TEP inguinal hernioplasty (61.09 minutes, p=0.876). CONCLUSIONS: The TEP inguinal hernioplasty allows the detection and repair of incidental obturator hernia. Through thorough inspection of the obturator canal, an asymptomatic obturator hernia can be detected and adequately treated within the same procedure, without the impact on the surgery duration, when performed by an experienced hernia surgeon.

BACKGROUND: The peroral "pull" technique and the direct "push" procedure are the two main methods for percutaneous endoscopic gastrostomy (PEG) placement. Although pull-PEG is generally recommended as the first-line modality, many oncological patients require a push-PEG approach to prevent tumor seeding or overcome tumor-related obstruction. OBJECTIVE: We aimed to compare the efficacy and safety of both PEG procedures in cancer patients. METHODS: We retrospectively analyzed all consecutive PEG procedures within a tertiary oncological center. Patients were followed up with the hospital databases and National Cancer Registry to assess the technical success rate for PEG placement, the rate of minor and major adverse events (AEs), and 30-day mortality rates. We compared those outcomes between the two PEG techniques. Finally, risk factors for PEG-related adverse events were analyzed using a multivariable Cox proportional-hazard regression model adjusted for patients' sex, age, performance status (ECOG), Body Mass Index (BMI), diabetes, chemoradiotherapy (CRT) status (pre-/current-/post-treatment), and type of PEG. RESULTS: We included 1055 PEG procedures (58.7% push-PEG/41.4% pull-PEG) performed in 994 patients between 2014 and 2021 (mean age 62.0 [±10.7] yrs.; 70.2% males; indication: head-and-neck cancer 75.9%/other cancer 24.1%). The overall technical success for PEG placement was 96.5%. Although the "push" technique had a higher rate of all AEs (21.4% vs. 7.1%, Hazard Ratio [HR] = 2.9; 95% CI = 1.9-4.3, p < 0.001), most of these constituted minor AEs (71.9%), such as tube dislodgement. The methods had no significant difference regarding major AEs and 30-day mortality rates. Previous CRT was associated with an increased risk of major AEs (hazard ratio = 2.7, 95% CI = 1.0-7.2, p = 0.042). CONCLUSION: The risk of major AEs was comparable between the push- and pull-PEG techniques in cancer patients. Due to frequent tube dislodgement in push-PEG, the pull technique may be more suitable for long-term feeding. Previous CRT increases the risk of major AEs, favoring early ("prophylactic") PEG placement when such treatment is expected.

Transcutaneous electrical acupoint stimulation (TEAS) is an emerging therapeutic approach that combines the effects of transcutaneous electrical nerve stimulation (TENS) with acupuncture point stimulation. Due to its noninvasive nature, it possesses relative advantages over traditional acupuncture and needle-based electrostimulation. Despite the large number of randomized clinical trials (RCTs) describing the effectiveness of TEAS in different applications, its role and mechanism are still not fully understood. The aim of this study was to systematically compare and summarize the latest studies examining a variety of TEAS applications in clinical practice. Databases, including Medline (PubMed), Cochrane Library and Google Scholar were searched without any time restrictions (as of March 2021). The analysis was performed according to the Cochrane Collaboration criteria. Out of 637 studies, only 22 RCTs were selected. Nine studies evaluated the impact of TEAS on nausea and vomiting (NV), showing beneficial effects compared to standard therapy. Eight RCTs examined the effectiveness of TEAS in pain management, reporting pain alleviation described using the visual analog scale (VAS) and lowering of total opioid doses. Improvement of postoperative recovery, in vitro fertilization and pregnancy outcomes, as well as display of cardioprotective properties were found to positively correlate with TEAS. As a noninvasive modality with advantages over classical acupuncture and needle-based electrostimulation, TEAS may be a valuable tool in clinical practice, particularly for pain and NV management. However, considering the methodological quality of the RCTs, rigorous large-scale clinical trials are required to evaluate the clinical utility of this method.

BACKGROUND: The purpose of this study is to evaluate the efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS) in the postoperative treatment of patients undergoing inguinal hernia repair compared with sham and no treatment group. METHODS: This study is a protocol for a three-armed, single-blinded, placebo-controlled randomized controlled trial. Ninety participants scheduled for inguinal hernia repair will be randomly assigned to the TEAS group (n = 30), sham group (n = 30), and control group (n = 30). The TEAS group will receive treatment using four portable coin-sized electro-stimulators at both local and distal acupuncture points. The sham group will receive sham treatment with mock electrostimulation. The treatment groups will receive mixed frequency stimulation (alternating at 2 and 100 Hz every 3 s) in continuous mode for 30 min at intervals of 2 h for 24 h postoperatively. The control group will receive postoperative pain control using patient-controlled analgesia (PCA) device. The primary outcome is the total morphine dose received in the postoperative period (mg) using PCA 24 h after surgery. The number of PCA demands (i.e., times the button will be pressed) and delivered bolus doses, score on the Visual Analogue Scale, opioid-related side effects, the requirement for supplemental medications, score on the Hospital Anxiety and Depression Scale (HADS), and blood levels of stress hormones cortisol and prolactin. DISCUSSION: The results of this trial will determine whether TEAS with intensified stimulation protocol is a safe and effective option for reducing analgesic consumption and postoperative pain.

Given the rising rate of opioid-related adverse drug events during postsurgical pain management, a nonpharmacologic therapy that could decrease analgesic medication requirements would be of immense value. We designed a prospective, placebo-and-randomized controlled trial to assess the clinical effect of transcutaneous acupoint electrical stimulation (TEAS) on the postoperative patient-controlled analgesia (PCA) requirement for morphine, as well as side effects and recovery profile after inguinal hernia repair. Seventy-one subjects undergoing inguinal hernia repair with a standardized anesthetic technique were randomly assigned to one of three analgesic treatment regimens: PCA + TEAS (n = 24); PCA + sham-TEAS (no electrical stimulation) (n = 24), and PCA only (n = 23). The postoperative PCA requirement, pain scores, opioid-related side effects, and blood cortisol levels were recorded. TEAS treatment resulted in a twofold decrease in the analgesic requirement and decreased pain level reported by the patients. In addition, a significant reduction of cortisol level was reported in the TEAS group at 24 h postoperatively compared to the sham and control groups. We conclude that TEAS is a safe and effective option for reducing analgesic consumption and postoperative pain following inguinal hernia repair.
ABSTRACT
BACKGROUND: ARID1A (also known as BAF250a, p270 or SMARCF1) is a major component of the mammalian SWI/SNF family that is involved in the regulation of the chromatin structure. ARID1A gene mutations have been associated with many types of malignancies, including breast cancer. This study aimed to explore the expression of BAF250a protein in breast cancer and its association with the clinical and pathological characteristics and prognosis of breast cancer. METHODS: We assessed the BAF250a expression in 119 invasive breast carcinomas samples and 92 healthy control and correlated this expression pattern with various clinical and pathologic parameters including histologic type and grade, tumor size, lymph node status, estrogen receptor (ER) status, progesterone receptor (PR) status. Immunohistochemical analysis of BAF250a, ER, PR, was carried out, and evaluation of stainings was performed. RESULTS: The mean value of BAF250a expression in the experimental group was higher than in healthy control (P=0.001). The expression is unrelated to age, menopausal status, lymph node status, tumor size and location, grade and histologic type of tumor, and hormonal status (ER, PR). CONCLUSIONS: These data suggest that BAF250a is overexpressed in breast cancers. BAF250a may play context-dependent tumor-promoting and tumor-suppressive roles in cancer.
