BACKGROUND: Migraine is an episodic disorder and a frequent form of headache. An impaired balance between free radical production and an impaired antioxidant defense system leading to oxidative damage may play a major role in migraine etiology. We sought to investigate whether dietary antioxidant quality score (DAQS) is associated with migraine intensity and frequency among women suffering from migraine.
METHODS: This cross-sectional study was conducted on 265 women. The data related to anthropometric measures and dietary intake were collected. DAQS score was calculated based on FFQ (food frequency questionnaire) vs. the reference daily intake (RDI) quantity. To measure migraine intensity, the migraine disability assessment questionnaire (MIDAS) and visual analog scale (VAS) were used. The frequency of headaches was defined as the days the participants had headaches in the last month and a 30-day headache diary was used.
RESULTS: The results of the study demonstrated that VAS, MIDAS, and frequency of headaches were reduced significantly from the low DAQS (poor quality of antioxidants) to high DAQS (high quality of antioxidants) after adjusting covariates. Also, multinomial regression showed there was an inverse association between higher DAQS and the frequency of headaches. In the adjusted model, subjects with the higher DAQS were 69% less likely to have moderate migraine disability, compared with those with the lower DAQS. Linear regression showed, there was an inverse association between vitamin C intake and the grades of pain severity.َAlso in a crude model, a negative association was found between vitamin E and the frequency of headaches.
CONCLUSIONS: In conclusion, Participants with higher DAQS had lower migraine intensity and headache frequency. In addition, the consumption of vitamin C may potentially associate with decreasing the severity of headaches. Dietary antioxidants should be monitored closely in individuals suffering from migraine.

UNASSIGNED: Head-mounted display (HMD) arises as an alternative display system for surgery. This study aimed to assess the utility of a stereoscopic HMD for exoscopic neurosurgery.
UNASSIGNED: The leading operator and assistants were asked to assess the various aspects of the HMD characteristics compared to the monitor display using a visual analog scale (VAS)-based questionnaire. The VAS score ranged from 0 to 10 (0, HMD was significantly inferior to the monitor; 5, HMD and monitor display were equal; and 10, HMD was significantly superior to the monitor).
UNASSIGNED: The surgeons and assistants used and evaluated HMD in seven exoscopic surgeries: three tumor removal, one aneurysm clipping, one anterior cervical discectomy and fusion, and two cervical laminectomy surgeries. The leading operators\' assessment of HMD-based surgery was not different from monitor-based surgery; however, the assistants evaluated the field of view, overall image quality, and the assisting procedure as better in MHD-based surgery than monitor-based surgery (P = 0.039, 0.045, and 0.013, respectively).
UNASSIGNED: HMD-based exoscopic neurosurgery can be performed at a similar quality as monitor-based surgery. Surgical assistants may benefit from using HMD-based surgery.

Background: Complex regional pain syndrome (CRPS) presents as persistent regional pain, both spontaneous and triggered. The demand persists for innovative treatments that patients can endure with minimal adverse effects. Hyperbaric oxygen therapy (HBOT) emerges as a possible intervention in this regard. Methods: The main objective of this work is to retrospectively analyse a case series of patients diagnosed with CRPS treated in the Centre of Hyperbaric Medicine Ostrava over two years (period 2018-2019). The HBOT was applied at 2.0-2.4 absolute atmosphere (ATA) once a day. Results: A total of 83 patients with CRPS were treated with HBOT. 98% of cases reported pain, 92% reported limitation of movement of the affected limb, 87% had swelling of the limb, 41% had lividity and 70% had sensory problems. The mean number of HBOT exposures was 22.0 ± 7.1. At the end of HBOT treatment, 86% of cases had symptoms relief. The mean VAS value of pain at rest before the start of HBOT was 3.2±3.0, after treatment it was 1.6±1.9 (p<0.001). In a pain at activity it was 6.1±2.4 and 3.7±2.4 (p<0.001), respectively, at the end of HBOT. The value of the functional assessment of the limb was 7.0±2.0 and 4.3±2.4 (p<0.001), respectively, at the end of treatment. 79 cases were included in the end-of-treatment assessment. 23 cases (29%) were evaluated as large clinically significant response, 48 cases (61%) were evaluated as partial response with minimally important difference. The results showed larger clinical HBOT effect in cases of disease duration up to 3 and 6 months (p=0.029). Conclusions: The majority of patients improved pain and functional state of the affected limb. Our data also suggests the sooner after diagnosis of CRPS is HBOT started, the treatment has larger clinical effect. There was no serious HBOT-related complication or injury.

UNASSIGNED: Nasal packs are central to nasal surgeries. Primarily, these packs function by controlling bleeding, modulating pain and reducing adhesions postsurgery. However, the major setback of the currently used conventional nasal packs is the unbearable pain the patient undergoes upon removal of these packs. To overcome this shortcoming a variety of biodegradable packs have emerged. This study was aimed at evaluating the safety, efficacy and tolerability of VELNEZ nasal packs. VELNEZ, a patented Datt Mediproducts Pvt. Ltd. nasal pack, is one of its kind biodegradable composite that fragments within a few days of application.
UNASSIGNED: Eighty patients were included in an open label, interventional, single arm clinical study using clinical endpoints to investigate the safety and efficacy of nasal pack VELNEZ. The patients were questioned using a visual analog scale from discharge day to 28th postoperative day (9 follow-up visits) at regular intervals. The standardized questionnaires for hemorrhage control, relief from postoperative pain, moderate obstruction, and pain were used.
UNASSIGNED: A total of 76 patients were enrolled in the study and 74 patients completed the study. VELNEZ nasal pack played a significant role in controlling hemorrhage and reducing postoperative pain. The average hemorrhage control time was 7.49 ± 3.90 min with only 34.24% of population complaining of pain on the sixth day of surgery (follow-up 4). Forteen days postsurgery only 10.95% of subject population complained of postoperative pain. This biodegradable composite has an average fragmentation time of 4.7 days in the nasal cavity. In addition, this study did not observe any postoperative adverse events or serious adverse events.
UNASSIGNED: VELNEZ, a fragmentable nasal pack, is comfortable, safe, and effective against postsurgery bleeding and pain.

Background Endometriosis is a prevalent gynecological disorder characterized by extra-uterine endometrial-like tissue, causing substantial morbidity, including chronic pelvic pain and infertility. Little is known about the correlation between imaging findings and pain severity in endometriosis. Methods We conducted a prospective observational study, enrolling 150 women diagnosed with endometriosis. Clinical, imaging (MRI and transvaginal ultrasound (TVUS)), and histopathological criteria were used for diagnosis. Pain severity was assessed using the Visual Analog Scale (VAS). Statistical analysis included multivariate regression to identify predictors of pain severity. Results Imaging revealed common sites of endometriosis involvement, predominantly ovaries (73.3%) and rectovaginal septum (40%). Deep infiltrating endometriosis (DIE) was present in 30% of patients, predominantly affecting uterosacral ligaments (66.7% of DIE cases). Patients with ovarian endometriomas and DIE exhibited significantly higher VAS scores (7.6 ± 1.5 and 8.0 ± 1.2, respectively) compared to those without (6.5 ± 1.9 and 6.9 ± 1.8, respectively). Surgical intervention led to a significant reduction in VAS scores (from 7.4 ± 1.6 to 3.2 ± 1.7, p < 0.001), correlating with reductions in lesion size and extent observed in follow-up imaging. Conclusion Advanced imaging techniques, particularly MRI and TVUS, play a critical role in assessing pain severity in endometriosis. Ovarian endometriomas and DIE are independent predictors of increased pain severity, guiding personalized treatment strategies. Surgical excision of lesions, particularly in cases of DIE, offers substantial pain relief and improves quality of life, emphasizing the integration of imaging in clinical decision-making for optimal endometriosis management.

Background This study aimed to explore the potential efficacy and safety of laser therapy compared with traditional desensitizing treatments in the management of dentin hypersensitivity. Methodology A comprehensive observational study was conducted on 138 adult individuals aged 18-65 diagnosed with dentin hypersensitivity. Participants were allocated to either the laser therapy or traditional treatment group. The laser therapy group received treatment using the Fotona LightWalker® Erbium laser at 2,940 nm. The energy density was set at 20 J/cm² using continuous and contact modes, with the laser tip held perpendicularly to the irradiated site. Each session lasted five minutes, conducted bi-weekly for three months. Traditional treatment included the in-office application of 5% sodium fluoride varnish application once every 15 days for three months and the use of desensitizing toothpaste as part of regular oral hygiene routines. Follow-up assessments were conducted 6 and 12 months post-treatment to evaluate the longevity and stability of the treatment effects. Primary outcomes were assessed by dentin hypersensitivity reduction measured using Visual Analog Scale (VAS) scores and tactile hypersensitivity assessments. Results Laser therapy consistently surpassed traditional treatment in reducing dentin hypersensitivity, as reflected by the significantly lower VAS scores. Notably, at 3, 6, and 12 months, laser therapy demonstrated mean VAS scores of 2.5 (±1.5), 1.2 (±0.9), and 0.6 (±0.5), respectively, while the traditional treatment group exhibited higher scores (3.8 ± 1.2, 4.5 ± 1.0, and 4.0 ± 0.7, respectively). Statistical analysis revealed that these differences were highly significant (p < 0.001). Tactile hypersensitivity assessments echoed these findings, with laser therapy consistently maintaining lower scores (0.8 ± 0.7 at 6 months, 0.4 ± 0.3 at 12 months) compared to traditional treatment (3.5 ± 1.0 at 6 months, 4.0 ± 0.7 at 12 months) with statistical significance at all time points (p < 0.001). Conclusions Although this study lacks a randomized controlled design, the observed substantial reduction in VAS scores and tactile hypersensitivity assessments, along with the favorable safety profile of laser therapy, suggest its potential as an effective alternative for managing dentin hypersensitivity.

UNASSIGNED: Expectations may modify outcomes. However, studies often fail to measure expectations. This raises the need for a brief valid and reliable expectancy measure.
UNASSIGNED: To study treatment expectations in individuals entering acupuncture or rest, validity and test re-test reliability of a single-item expectancy measure graded on a category scale, a Numeric Rating Scale (NRS) and a Visual Analog Scale (VAS), and to identify psychometric differences between the scales.
UNASSIGNED: In this methodology study, treatment expectations were measured in 363 participants before they received acupuncture (genuine traditional penetrating or non-penetrating telescopic sham acupuncture, n = 239, 98%, responded) or a control treatment involving just rest (n = 120, 100%, responded), aimed to improve level of relaxation. A treatment expectancy measure, graded on a five-grade category scale, an eight-grade NRS and a 100 mm VAS, was tested for test re-test reliability. Level of expectation and relaxation was measured at baseline, pre- and post-therapy (n = 729 expectancy measurements).
UNASSIGNED: The participants scheduled for acupuncture or rest believed moderately (Inter Quartile Range, IQR, moderately-much) and much (IQR moderately-much) the treatment to be effective. The Intra-Class Correlation coefficient versus Kappa coefficient between test and re-test was .868/.868 for the category scale, .820/.820 for the NRS, and .856/.854 for the VAS. The middle step \"Believe moderately the treatment to be effective\" was equivalent with median 4 (IQR, 3-4) on NRS and median 52 mm (IQR 42-52) on VAS. The response rates were 708 (97%) on the category scale, 707 (97%) on the NRS, and 703 (96%) on the VAS. All three scales discriminated that pre-therapy expectations were more positive in the individuals who reported an improvement in relaxation level (P < .001-.003). The VAS presented higher responsiveness to detect expectancy changes over time (71% increased expectation), compared to the NRS (52% increased) and the category scale (12% increased), P < .001.
UNASSIGNED: Individuals entering acupuncture, or a control intervention, presented positive treatment expectations, and the expectancy measure presented satisfactory reliability, validity, high response rates, sensitiveness, and responsiveness. Integrative cancer therapy researchers who want to control for expectancy-related bias in clinical trials should consider measuring expectation using the single-item expectancy measure.

UNASSIGNED: To determine the minimal clinically important difference (MCID) for contact lens (CL)-related subjective responses and explore whether MCID values differ between subjective responses and study designs.
UNASSIGNED: This was a retrospective analysis of data from seven one-week bilateral crossover studies and 14 one-day contralateral CL studies. For comfort, dryness, vision, or ease of insertion, participants rated on a 0-100 visual analogue scale (VAS) and indicated lens preference on a five-point Likert scale featuring strong, slight, and no preferences. For each criterion, four MCID estimates were calculated and averaged: mean VAS score difference for \"slight preference,\" lower limit of 95% confidence interval VAS score difference for \"slight preference,\" difference in mean VAS score difference between \"slight\" and \"no preference\" and 0.5 standard deviation of VAS scores.
UNASSIGNED: The four calculation methods generated a small range of MCID values. For bilateral studies, the averaged MCID was 7.2 (range 5.4-8.8) for comfort, 8.1 (5.2-10.6) for dryness, 7.1 (5.5-9.3) for vision and 7.6 (6.0-10.5) for ease of insertion. For contralateral studies, the averaged MCID was 6.9 (6.1-7.6) for comfort at insertion and 7.5 (6.8-8.2) for end-of-day comfort.
UNASSIGNED: This work demonstrated very similar MCID values across subjective responses and study designs, in a population of habitual soft CL wearers. In all cases, MCID values were on average seven units on a 0 to 100 VAS.
UNASSIGNED: This work provides MCID values which are important for interpreting ocular subjective responses and planning clinical studies.

Background A common knee joint disorder is injury to the anterior cruciate ligament (ACL), which often requires surgery. Proper pain control after the surgery facilitates fast recovery and prevents chronic pain. To provide analgesia for knee procedures, the use of opioids, non-steroidal anti-inflammatory medications, and regional techniques are commonly employed. This study aims to evaluate the efficacy of adductor canal block (ACB) and femoral nerve block (FNB) for postoperative pain management after anterior cruciate ligament reconstructions (ACLRs). Methodology This prospective interventional study included 30 participants scheduled for patellar graft ACLR. They were assigned into groups, i.e., ACB and FNB, with 15 patients each. The evaluation occurred one day before the operation, and all surgical procedures were performed using spinal anesthesia. During the postoperative period, a 10-point visual analog scale (VAS) was utilized to quantify pain intensity at the end of the surgery and at various intervals after the surgery. Patients with a VAS score greater than 4 received either FNB or ACB using bupivacaine 0.125%. Duration of analgesia time, power of quadriceps muscle, and neurologic complications were documented. Results No statistically significant value was observed in the mean duration of analgesia between the patients in ACB (348.33 minutes) and the patients in FNB (363.06 minutes). No motor block was observed in 12 patients who received ACB, while only four patients had a motor-sparing effect among those who received FNB. No neurological adverse effects were observed in the study participants. Conclusions ACB provides an equal duration of analgesia similar to FNB, and ACB significantly spares motor strength and maintains higher quadriceps power than FNB.

OBJECTIVE: Adductor canal block (ACB) is widely performed for postoperative analgesia for total knee arthroplasty (TKA). The aim of this study is to compare surgeon-assisted and anesthesiologist-assisted (ultrasound-guided) adductor blocks in terms of postoperative analgesic efficacy.
METHODS: This study was designed as a double-blind, prospective and randomized trial. A total of 240 participants were randomly allocated to three groups: one where the surgeon performed the adductor canal block (ACBs), another where it was conducted by an anesthetist with ultrasound guidance (ACBa), and a third group without the adductor block. The follow-up management after the Total Knee Arthroplasty (TKA) procedure occurred on the first, third, and tenth days, as well as the twelfth week. Outcome measures comprised pain assessment using the Visual Analog Scale (VAS) and monitoring opioid analgesic consumption.
RESULTS: No significant differences in demographic profiles were observed between the groups. Groups ACBa and ACBs exhibited significantly lower VAS scores compared to the control group at both 3 and 12 h after surgery, with group ACBa showing the lowest VAS scores among all groups. However, at 1 day, 3 days, 10 days and 12 weeks after surgery, there was no significant difference in VAS scores between the ACBa and ACBs groups. On the first three days, the ACBa group had the lowest opioid consumption and the lowest total opioid consumption. The differences in VAS scores between the groups began to decrease on the first day after surgery.
CONCLUSIONS: The adductor canal block (ACB) has been demonstrated to be an effective method of reducing pain in patients undergoing total knee replacement (TKR) in the postoperative period. Nevertheless, despite the pronounced impact that ACB performed by an anesthesiologist under ultrasound guidance has on VAS scores according to intraoperative ACB by surgeons, its effect on clinical outcomes has not been demonstrated.
BACKGROUND: This study was retrospectively registered with the Clinical Trials Registry Platform on July 31, 2024 (NCT06533085).
