BACKGROUND: Knee osteoarthritis (OA) is a leading cause of disability among the elderly and is often exacerbated by obesity. Research supports weight loss and exercise therapy as key strategies for managing knee OA-related disability. Concurrently, telemedicine is becoming a popular healthcare approach. This study aimed to develop and evaluate an 8-week tele-education programme\'s impact on weight control and knee OA outcomes.
METHODS: Participants with knee OA and obesity were included. Baseline data on pain (VAS index), physical activity (GPAQ questionnaire), and quality of life (EQ5D and KOOS questionnaires) were collected. Performance tests, including the 30-second Chair Stand test (30CST) and the Timed Up-and-Go test (TUG), were recorded. Participants were randomly divided into two groups: a control group receiving oral advice on diet and exercise, and an intervention group receiving educational videos on nutrition, lifestyle changes, physical activity, individualised exercises, and psychosocial support. Evaluations were repeated after 8 weeks.
RESULTS: Data from 25 of 30 participants were analysed. In the intervention group, body composition, waist, and abdominal circumference decreased significantly (p < 0.05). The KOOS questionnaire showed significant improvements in pain, activity, and daily tasks (p = 0.00). The EQ5D questionnaire and health satisfaction also showed positive results within the intervention group (p = 0.00) and between groups (p = 0.008). The pain index improved significantly within (p = 0.00) and between groups (p = 0.02). Functional test results were significant within the intervention group (p = 0.00) and between groups (p = 0.017 for 30CST and p = 0.004 for TUG).
CONCLUSIONS: An 8-week tele-education programme for weight control and exercise therapy in knee OA patients significantly improved body composition, quality of life, and functional performance. Given the costs of obesity and knee OA on both people and the health system, tele-education can be a cost-effective treatment strategy.

Progressive cachexia and malnutrition severely impact the physical and mental condition of cancer patients. Pain is a prognostic factor for shorter survival in cancer patients, and coping strategies are crucial for adapting to treatment and dietary regimens. This study assessed pain levels, pain-related beliefs, and coping strategies as factors increasing malnutrition risk in 257 lung cancer patients. Sociodemographic and clinical data were collected from medical records. The Mini Nutritional Assessment (MNA), Visual Analog Scale (VAS), Beliefs about Pain Control Questionnaire (BPCQ), and Coping Strategies Questionnaire (CSQ) were used. Overall, 42.8% of patients were at risk of malnutrition, and 17.5% were malnourished. Nutritional status negatively correlated with CSQ domains: reinterpretation of pain (RP: rho = -0.194; p = 0.002), catastrophizing (CP: rho = -0.414; p = 0.001), ignoring pain (IP: rho = -0.198; p = 0.001), praying/hoping (PH: rho = -0.253; p < 0.001), and coping self-statements (CS: rho = -0.172; p = 0.006); and BPCQ domains: the power of doctors (PD: rho = -0.196; p = 0.002) and VAS (rho = -0.451; p < 0.001). Nutritional status positively correlated with CSQ domains: pain control (PC: rho = 0.499; p < 0.001) and the ability to reduce pain (AR: rho = 0.512; p < 0.001). In multivariate regression analysis, a better nutritional status was associated with a younger age (β = -0.094; p < 0.001), non-small-cell lung cancer (NSCLC) (β = 1.218; p = 0.037), a greater ability to reduce pain (CSQ-AR) (β = 0.901; p < 0.001), lower catastrophizing (CSQ-CP) (β = -0.165; p = 0.001), and lower pain perceived (VAS) (β = 0.639; p < 0.001). Statistical analyses included Spearman\'s correlation and multivariate regression with a significance level of p < 0.05. Patients with a normal nutritional status had reduced doctor involvement in pain control, less frequent negative coping strategies, and more common positive coping strategies. A normal nutritional status correlates with lower perceived pain. A better nutritional status is linked to a younger age, NSCLC, lower pain levels, greater pain reduction ability, and lower scores in pain catastrophizing.

OBJECTIVE: Refractory cancer-induced bone pain (CIBP) affects a patient\'s functional capacity and quality of life, but there is limited evidence to guide opioid choice. We assessed the feasibility, tolerability and possible efficacy of methadone rotation (MR) compared to other opioid rotations (OOR) in this cohort.
METHODS: Adults with CIBP and worst pain intensity ≥ 4/10 and/or opioid toxicity graded ≥ 2 on the Common Terminology Criteria for Adverse Events were randomised 1:1 to methadone or another opioid rotation. Standardised assessment tools were used at pre-defined study time points up to 14 days.
RESULTS: Of 51 eligible participants, 38 (74.5%) consented, and 29 (76.3%, MR: 14, OOR: 15) completed the fourteen days follow-up post-opioid rotation. Both groups displayed significant reduction in average (MR: d =  - 1.2, p = 0.003, OOR: d =  - 0.8, p = 0.015) and worst pain (MR: d =  - 0.9, p = 0.042, OOR: d =  - 0.6, p = 0.048) and total pain interference score (MR: d =  - 1.1, p = 0.042, OOR: d =  - 0.7, p = 0.007). Oral morphine equivalent daily dose was reduced significantly in MR compared to the OOR group (d =  - 0.8, p = 0.05). The incidence of opioid-related adverse events following MR was unchanged but lower in the OOR group (d = 0.9, 95% CI 0.1,1.7, p = 0.022). There were no within-group or between-group differences in satisfaction with analgesia at the end of the study.
CONCLUSIONS: This pilot study demonstrated that MR and OOR in patients with refractory CIBP are feasible, safe and acceptable to patients. Appropriately powered multi-centre randomised controlled studies are needed to confirm the efficacy of MR and OOR in this cohort.

BACKGROUND: Effective pain management is crucial for the successful completion of dental procedures in children. Research has examined whether computerized intraosseous anesthesia (CIOA) could serve as a safe and viable substitute for the conventional inferior alveolar nerve block (IANB) technique in pediatric patients. This study investigates the efficacy of CIOA, aiming to determine its effectiveness as an alternative anesthesia method.
OBJECTIVE: This study compared the efficacy of local intraosseous anesthesia using a computerized device (QuickSleeper 5) to conventional IANB anesthesia on cooperation and pain perception in children, using a randomized controlled trial design.
METHODS: The study included 88 healthy children, aged between 6 and 9 years, who required pulpotomy for their mandibular second primary molars. The study was approved by the local research ethics committee and registered at clinicaltrials.gov (NCT05193487). The heart rate and Venham behavior rating scale were recorded and analyzed. Categorical data were analyzed using Fisher\'s exact test. Age and heart rate were compared using an independent t-test for intergroup comparison. The intragroup comparison was carried out using repeated measures ANOVA, followed by the Bonferroni post hoc test. The Mann-Whitney U-test was used to analyze the Venham scale scores. The significance level was set at p < .05 RESULTS: The mean Venham score was slightly higher in the IANB group than in the CIOA group, but was not statistically significant (p = .852). One minute after anesthesia administration, the heart rate (beats per minute [BPM]) was significantly higher in the IANB group (92.30 ± 13.45) than in the CIOA group (83.20 ± 10.40) (p < .001). Additionally, there was a significant difference in heart rate values measured at different intervals within the IANB group.
CONCLUSIONS: The QuickSleeper 5 device was found to be a feasible alternative for IANB in children over 6 years old.

Background/Objectives: The aim of this study was to establish a histologic baseline for cryoanalgesia of 2 min duration and evaluate the effects of different freeze durations. Methods: A porcine model was used in which the application of bilateral cryoanalgesia from intercostal spaces T3-T7 was completed via partial median sternotomy. The animals were kept alive for 7 days and the ribcages were sent to a specialized center for histopathologic analysis of the freezing injury. Results: Forty freezing lesions were completed and analyzed histologically. Thirty-eight (95%) of the cryo-lesions presented 100% nerve fiber degeneration at or distal to the ablation site, with preservation of the perineural connective tissue, as intended. The two unaffected nerves were found to be physically located outside of the freezing area. Conclusions: The complete axonal degeneration with preservation of the perineural tissue opens the possibility to shorter freezing times than the recommended 2 min. Visualization of the nerve and positioning of the probe is important in ensuring the proper effect on the nerve. This histologic analysis confirms the process triggered by cryoanalgesia that, until now, had only been assumed.

BACKGROUND: In patients who are candidates for craniotomy, scalp nerve blocks have been shown to be effective in relieving pain intensity as well as postoperative hemodynamic stability after surgery, but the results have been inconsistent. We aimed to assess the effect of scalp block on pain control, intraoperative drug use under Analgesia Nociception Index (ANI) monitoring, and postoperative pain in patients who were candidates for elective craniotomy.
METHODS: In this randomized, single-blinded clinical trial study, candidates for craniotomy were randomly (using the block randomization method) divided into 2 groups before entering the operating room. The first group received a scalp block with bupivacaine (intervention), and the second group did not receive a scalp block (control) besides the routine anesthetic procedure in these patients. ANI, hemodynamic parameters, and the amounts of received remifentanil were conducted and compared.
RESULTS: Patients under scalp block received less dosage of fentanyl than the nonscalp block group (mean = 57.14 ± 15.59 mcg vs. 250.00 ± 65.04 mcg, respectively). Similarly, the dose of remifentanil required in the scalp block group was less (mean = 3.04 ± 1.95 mg and 5.54 ± 2.57 mg, respectively). No difference was observed in hemodynamic parameters such as blood pressure and heart rate (before, during, and after surgery). However, the group receiving scalp block had higher ANI means than the control group.
CONCLUSIONS: Scalp nerve block has an effective role in pain control (increasing ANI), consequently reducing the need for analgesic drugs such as fentanyl and remifentanil following craniotomy without changing the hemodynamic condition.

BACKGROUND: Pain experienced by women in the perinatal period constitutes a complex and multifaceted phenomenon. The aim of the study was to assess conditions of pain locus of control and pain reduction in post-cesarean section parturients.
METHODS: A cross-sectional quantitative study with convenience sampling was performed among 175 hospitalized post-cesarean section women in hospitals in Eastern Poland in accordance with the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) statement. A self-design questionnaire regarding general information and obstetrics/gynaecology medical interview, The Pain Coping Strategies Questionnaire (CSQ) and The Beliefs about Pain Control Questionnaire (BPCQ) were used. The inclusion criteria were as follows (1) age of ⩾18 years old; (2) cesarean section (CS); (3) period from the 13th hour to the end of the 72nd hour after the procedure; and (4) informed consent. The data was analyzed with IBM SPSS Statistics.
RESULTS: Internal locus of control (M = 14.02) was provided the highest value by the parturients and followed by chance events (M = 12.61) and doctors\' power (M = 12.18). Dominant coping with pain strategies in the post-cesarean parturients were coping self-statements (M = 19.06), praying or hoping (M = 18.86). The parturients assessed their pain coping (M = 3.31) strategies along with pain reduction (M = 3.35) at the moderate level. Higher pain control was correlated with cognitive pain coping strategies (β = 0.305; t = 4.632; p < 0.001), internal pain control β = 0.191; t = 2.894; p = 0.004), cesarean section planning (β = -0.240; t = -3.496; p = 0.001) and past medical history of CS (β = 0.240; t = 3.481; p = 0.001). The skill of reduction of pain was positively associated with cognitive pain coping strategies (β = 0.266; t = 3.665; p < 0.001) and being in subsequent pregnancy (β = 0.147; t = 2.022; p = 0.045). Catastrophizing and hoping were related to lower competences of coping with pain (B = - 0.033, SE = 0.012, β = - 0.206, T = -2.861).
CONCLUSIONS: The study allowed for identification and better comprehension of factors conditioning pain control and pain reduction in parturients after the cesarean section. Furthermore, a stronger belief that pain can be dealt with is found in the parturients characterized by cognitive pain coping strategies and internal pain locus of control. The skill of reduction of pain is related to cognitive coping strategy and procreation status.

BACKGROUND: Pain following orthodontic treatment is a common reason for apprehension and treatment discontinuation. Research on modalities to control pain in orthodontic patients has gained special attention. Low-level laser therapy (LLLT) is studied as an alternative pain management modality free of the adverse effects of analgesic medications.
OBJECTIVE: This study evaluated the effectiveness of photobiomodulation therapy (PBMT) for pain control following the activation of a closing loop for canine retraction.
METHODS: This is a split-mouth, placebo-controlled, single-blinded randomized clinical trial that evaluated 16 patients who need canine retraction using closing loops. Two maxillary quadrants were allotted into test and control groups using the coin toss method. In the test group, a low-intensity laser with 810 nm wavelength for 60 seconds in pulsated non-contact mode was used in the buccal, palatal, mesial, and distal regions of the canine immediately after activating the loop. The control site received placebo radiation. The pain level was recorded 2, 24, 48, and 72 hours after intervention in the control and test groups using the Visual Analogue Scale (VAS). The test and control groups were compared using Student\'s t-test. A p-value ≤0.05 was considered statistically significant. Analyses were conducted using IBM SPSS Statistics for Windows, Version 25.0 (Released 2017; IBM Corp., Armonk, New York, United States).
RESULTS: Both groups had a significant statistical difference in the pain score. The laser group showed a statistically significant lower pain score compared to the control group at all time points.
CONCLUSIONS: Photobiomodulation by 810 nm 300 mW diode laser can effectively reduce pain following the retraction of maxillary canines.

UNASSIGNED: This article aimed to assess the efficacy of peritonsillar infiltration with dexmedetomidine-ropivacaine versus tramadol-ropivacaine for pain control and sedation after tonsillectomy in pediatric patients.
UNASSIGNED: This double-blind clinical trial recruited 99 eligible children (4-8 years old) undergoing tonsillectomy and assigned to three block-randomized groups, receiving dexmedetomidine-ropivacaine (group A), tramadol-ropivacaine (group B), or placebo-ropivacaine (group C). The vital signs included blood pressure, heart rate, and SaO2 before anesthesia induction, during surgery at regular intervals until 24 h after surgery. The duration of surgery and recovery, complications, and analgesic consumption were recorded and pain scores were measured by Children\'s Hospital of Eastern Ontario Pain Scale (CHEOPS) and Oucher scales as well as sedation scores by the Wilson sedation scale. Data were analyzed within SPSS 20 at a significance level of 0.05.
UNASSIGNED: The lowest pain scores were measured by the CHEOPS scale in the dexmedetomidine-ropivacaine group (P < 0.05). Statistically significant difference was observed in the CHEOPS pain score between the first two groups at 30 min, 1 h, 2 h, and 4 h after surgery (P < 0.01). The differences were revealed in the Oucher pain assessments among all groups from the time of recovery to four postoperative hours (P < 0.05), with the lowest in the dexmedetomidine-ropivacaine group whose sedation score was greater during recovery and 5 min after surgery (P < 0.05). Subjects in tramadol group had six cases of dizziness and nausea, while no side effects were observed in two other groups (P < 0.05). Only seven participants receiving dexmedetomidine required acetaminophen, but 29 in the tramadol group and all in the placebo group demanded to receive acetaminophen (P = 0.001).
UNASSIGNED: The authors concluded that dexmedetomidine as an adjuvant to ropivacaine has better performance in local infiltration for intra- and post-tonsillectomy analgesia and postoperative sedation, without any special side effects (like the placebo group), and that it hence is recommended to be used for local infiltration during tonsillectomy.
