[Two kinds of percutaneous endoscopic lumbar decompression in the treatment of single level lumbar lateral recess stenosis].

OBJECTIVE: To prospectively compare the clinical efficacy and radiographic outcomes between interlaminar percutaneous endoscopic lumbar decompression(IL-PELD) and transforaminar percutaneous endoscopic lumbar decompression(TF-PELD) in the treatment of single-segment lumbar lateral recess stenosis. METHODS: From April 2018 to July 2021, 85 patients with single-segment lumbar lateral recess stenosis underment percutaneous endoscopic lumbar decompression.There were 44 males and 41 females, aged from 49 to 81 years old with an average of (65.5±8.3) years old, duration of lumbar lateral recess stenosis ranging from 3 to 83 months with an average of (26.7±16.5) months. They were divided into IL-PELD group and TF-PELD group according to the different operation methods. There were 47 patients in the IL-PELD group, including 28 males and 19 females aged from 50 to 80 yeaes old with an average age was (66.7±9.3) years old. The disease duration ranged from 3 to 65 months with an average of (25.7±15.0) months. There were 38 patients in the TF-PELD group, including 16 males and 22 females, aged from 51 to 78 years old with an average of(64.1±7.6) years old. The disease duration ranged from 4 to 73 months with an average of (27.9±18.3) months The operation time, intraoperative blood loss, intraoperative fluoroscopy, hospitalization day and complications of the two groups were recorded. Visual analogue scale (VAS) to evaluate low back pain and lower limb pain, Oswestry disability index(ODI) to evaluate lumbar function in preoperative and postoperative period(1month, 6 months and last follow-up)were recorded. the sagittal diameter of the lateral recess of the responsible intervertebral space in preoperative and 1 week after the operation were recorded. RESULTS: The operation was successfully completed in both groups without serious complications such as vascular injury, dural sac tear and nerve injury. The operation time in IL-PED group(69.3±19.3)min was significantly longer than that in TF-PELD group(57.5±14.5)min (P<0.05). There was no significant difference in the intraoperative blood loss between the two groups (P>0.05). The number of intraoperative fluoroscopy in TF-PELD group (8.8±2.6)times was significantly higher than that in IL-PED group(4.8±1.2)times (P<0.05). The hospitalization days of the two groups were not statistically significant (P>0.05). VAS for low back and lower extremity pain and ODI were (5.1±2.2), (6.9±1.3) scores and (71.4±12.6) % in IL-PELD group, and (4.7±1.8), (6.9±1.3) scores and (68.4±13.9)% in TF-PELD group. In the IL-PELD group, the VAS of low back pain was (2.4±1.5), (1.6±0.8), (1.4±0.9) scores, and the VAS of lower extremity pain was (3.0±1.2), (1.6±0.7), (1.5±1.0) scores, ODI was (32.6±11.9) %, (17.4±6.5) %, (19.3±9.3)%;In TF-PELD group, the VAS of low back pain was (2.6±1.4), (1.5±0.6), (1.4±1.0) scores, and the VAS of lower extremity pain was (2.8±1.2), (1.6±0.6), (1.5±1.2) scores, The ODI was (32.0±11.2) %, (15.0±6.1) %, and (20.0±11.3) %. The VAS and ODI of the two groups at each time point after operation were significantly improved compared with those before operation (P<0.05), but there was no statistically significant difference between the groups (P>0.05), and there was no statistically significant difference in the interaction between different time points and groups (P>0.05). At 1 week after operation, the sagittal diameter of lateral recess in both groups was significantly increased compared with that before operation (P<0.05), but there was no significant difference between the two groups at each time point (P>0.05). According to the modified Macnab criteria, IL-PELD group was rated as excellent in 24 cases, good in 19 cases and fair in 4 cases. In TF-PELD group the results were excellent in 19 cases, good in 15 cases, fair in 3 cases and poor in 1 case. There was no significant difference between the two groups (P>0.05). CONCLUSION: IL-PELD and TF-PELD can expand the lateral recess in the treatment of single level lumbar lateral recess stenosis, and have achieved good clinical effects.

The impact of scaffolded and non-scaffolded suicidal virtual human interaction training on clinician emotional self-awareness, empathic communication, and clinical efficacy.

BACKGROUND: Clinicians working with patients at risk of suicide often experience high stress, which can result in negative emotional responses (NERs). Such negative emotional responses may lead to less empathic communication (EC) and unintentional rejection of the patient, potentially damaging the therapeutic alliance and adversely impacting suicidal outcomes. Therefore, clinicians need training to effectively manage negative emotions toward suicidal patients to improve suicidal outcomes. METHODS: This study investigated the impact of virtual human interaction (VHI) training on clinicians' self-awareness of their negative emotional responses, assessed by the Therapist Response Questionnaire Suicide Form, clinicians' verbal empathic communication assessed by the Empathic Communication and Coding System, and clinical efficacy (CE). Clinical efficacy was assessed by the likelihood of subsequent appointments, perceived helpfulness, and overall interaction satisfaction as rated by individuals with lived experience of suicide attempts. Two conditions of virtual human interactions were used: one with instructions on verbal empathic communication and reminders to report negative emotional responses during the interaction (scaffolded); and the other with no such instructions or reminders (non-scaffolded). Both conditions provided pre-interaction instructions and post-interaction feedback aimed at improving clinicians' empathic communication and management of negative emotions. Sixty-two clinicians participated in three virtual human interaction sessions under one of the two conditions. Linear mixed models were utilized to evaluate the impact on clinicians' negative emotional responses, verbal empathic communication, and clinical efficacy; and to determine changes in these outcomes over time, as moderated by the training conditions. RESULTS: Clinician participants' negative emotional responses decreased after two training sessions with virtual human interactions in both conditions. Participants in the scaffolded condition exhibited enhanced empathic communication after one training session, while two sessions were required for participants in the non-scaffolded condition. Surprisingly, after two training sessions, clinical efficacy was improved in the non-scaffolded group, while no similar improvements were observed in the scaffolded group. CONCLUSION: Lower clinical efficacy after virtual human interaction training in clinicians with higher verbal empathic communication suggests that nonverbal expressions of empathy are critical when interacting with suicidal patients. Future work should explore virtual human interaction training in both nonverbal and verbal empathic communication.

[Comparison of Clinical Effects of Cortical Bone Trajectory Screws and Traditional Pedicle Screws in Posterior Lumbar Fusion]. / è °æ¤ŽåŽè·¯èžåˆæœ¯ä¸­çš®è´¨éª¨è½¨è¿¹èžºé’‰å’Œä¼ ç»Ÿæ¤Žå¼“æ ¹èžºé’‰çš„ä¸´åºŠæ•ˆæžœæ¯”è¾ƒ.

Objective: To compare the clinical effects of cortical bone trajectory screws and traditional pedicle screws in posterior lumbar fusion. Methods: A retrospective study was conducted to analyze lumbar degeneration patients who underwent surgical treatment at our hospital between January 2016 and January 2019. A total of 123 patients who met the inclusion criteria were enrolled. The subjects were divided into two groups according to their surgical procedures and the members of the two groups were matched by age, sex, and the number of fusion segments. There were 63 patients in the traditional pedicle screws (PS) group and 60 in the cortical bone trajectory screws (CBTS) group. The outcomes of the two groups were compared. The primary outcome measures were perioperative conditions, including operation duration, estimated intraoperative blood loss (EBL), and length-of-stay (LOS), visual analog scale (VAS) score, Oswestry Disability Index (ODI) score, and interbody fusion rate. The secondary outcome measures were the time to postoperative ambulation and the incidence of complications. VAS scores and ODI scores were assessed before operation, 1 week, 1 month, 3 months, and 12 months after operation, and at the final follow-up. The interbody fusion rate was assessed in 1 year and 2 years after the operation and at the final follow-up. Results: The CBTS group showed a reduction in operation duration ([142.8±13.1] min vs. [174.7±15.4] min, P<0.001), LOS ([9.5±1.5] d vs. [12.0±2.0] d, P<0.001), and EBL ([194.2±38.3] mL vs. [377.5±33.1] mL, P<0.001) in comparison with the PS group. The VAS score for back pain in the CBTS group was lower than that in the PS group at 1 week and 1 month after operation and the ODI score in the CBTS group was lower than that in the PS group at 1 month after operation, with the differences being statistically significant (P<0.05). At each postoperative time point, the VAS score for leg pain and the interbody fusion rate did not show significant difference between the two groups. The VAS score for back and leg pain and the ODI score at each time point after operation in both the CBTS group and the PS group were significantly lower than those before operation (P<0.05). No significant difference was found in the time to postoperative ambulation or the overall complication incidence between the two groups. Conclusion: The CBTS technique could significantly shorten the operation duration and LOS, reduce EBL, and achieve the same effect as the PS technique does in terms of intervertebral fusion rate, pain relief, functional improvement, and complication incidence in patients undergoing posterior lumbar fusion.

Comparison of the clinical effects of dual-modality endoscopy and traditional laparotomy for the treatment of intra- and extrahepatic bile duct stones.

BACKGROUND: Bile duct stones (BDSs) may cause patients to develop liver cirrhosis or even liver cancer. Currently, the success rate of surgical treatment for intrahepatic and extrahepatic BDSs is not satisfactory, and there is a risk of postoperative complications. AIM: To compare the clinical effects of dual-modality endoscopy (duodenoscopy and laparoscopy) with those of traditional laparotomy in the treatment of intra- and extrahepatic BDSs. METHODS: Ninety-five patients with intra- and extrahepatic BDSs who sought medical services at Wuhan No.1 Hospital between August 2019 and May 2023 were selected; 45 patients in the control group were treated by traditional laparotomy, and 50 patients in the research group were treated by dual-modality endoscopy. The following factors were collected for analysis: curative effects, safety (incision infection, biliary fistula, lung infection, hemobilia), surgical factors [surgery time, intraoperative blood loss (IBL) volume, gastrointestinal function recovery time, and length of hospital stay], serum inflammatory markers [tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-8], and oxidative stress [glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), malondialdehyde (MDA), and advanced protein oxidation products (AOPPs)]. RESULTS: The analysis revealed markedly better efficacy (an obviously higher total effective rate) in the research group than in the control group. In addition, an evidently lower postoperative complication rate, shorter surgical duration, gastrointestinal function recovery time and hospital stay, and lower IBL volume were observed in the research group. Furthermore, the posttreatment serum inflammatory marker (TNF-α, IL-6, and IL-8) levels were significantly lower in the research group than in the control group. Compared with those in the control group, the posttreatment GSH-Px, SOD, MDA and AOPPs in the research group were equivalent to the pretreatment levels; for example, the GSH-Px and SOD levels were significantly higher, while the MDA and AOPP levels were lower. CONCLUSION: Dual-modality endoscopy therapy (duodenoscopy and laparoscopy) is more effective than traditional laparotomy in the treatment of intra- and extrahepatic BDSs and has a lower risk of postoperative complications; significantly shortened surgical time; shorter gastrointestinal function recovery time; shorter hospital stay; and lower intraoperative bleeding volume, while having a significant inhibitory effect on excessive serum inflammation and causing little postoperative oxidative stress.

Evaluation of the efficacy of autogenous tibial periosteal bone grafting in the treatment of osteochondral lesions of the talus and analysis of three-dimensional factors in the necrotic zone.

PURPOSE: This study aims to explore the clinical value of autogenous tibial periosteal bone grafting in the treatment of osteochondral lesions of the talus (OLT) and analyze the three-dimensional factors in the necrotic zone of the talus. METHODS: A retrospective analysis was performed on 36 patients who underwent autogenous tibial periosteal bone grafting in the Foot and Ankle Surgery Department of our hospital between September 2018 and September 2022. The American Orthopaedic Foot and Ankle Society (AOFAS), Visual Analogue Scale (VAS), and Chinese Short-Form 36 Health Survey (SF-36) were used to evaluate treatment efficacy prior to surgery and at the last follow-up. Furthermore, Mimics 21.0 software was employed to measure the three-dimensional data of the necrotic area, including surface area, volume, and depth, in order to investigate their potential impact on patient prognosis. RESULTS: Among the 36 OLT patients who obtained complete follow-up, there were 22 males and 14 females. No complications such as surgical site infection, non-union of cartilage, post-traumatic arthritis, or donor site pain were observed. The AOFAS, VAS, and Chinese SF-36 scores of all patients at the last follow-up showed significant improvement compared to preoperative values. There was no significant correlation between the AOFAS, VAS, and Chinese SF-36 scores at the last follow-up and the depth, surface area, and volume of the necrotic zone. CONCLUSION: The use of autogenous tibial periosteal bone grafting can safely and effectively treat Hepple V OLT. Additionally, there is no significant correlation between the three-dimensional factors of the necrotic area and the prognosis of the patients.

Assessment of disease control rate and safety of sorafenib in targeted therapy for advanced liver cancer.

OBJECTIVE: The clinical efficacy and safety of sorafenib in patients with advanced liver cancer (ALC) were evaluated based on transarterial chemoembolization (TACE). METHODS: 92 patients with ALC admitted to our hospital from May 2020 to August 2022 were randomly rolled into a control (Ctrl) group and an observation (Obs) group, with 46 patients in each. Patients in the Ctrl group received TACE treatment, while those in the Obs group received sorafenib molecular targeted therapy (SMTT) on the basis of the treatment strategy in the Ctrl group (400 mg/dose, twice daily, followed by a 4-week follow-up observation). Clinical efficacy, disease control rate (DCR), survival time (ST), immune indicators (CD3+, CD4+, CD4+/CD8+), and adverse reactions (ARs) (including mild fatigue, liver pain, hand-foot syndrome (HFS), diarrhea, and fever) were compared for patients in different groups after different treatments. RESULTS: the DCR in the Obs group (90%) was greatly higher to that in the Ctrl group (78%), showing an obvious difference (P < 0.05). The median ST in the Obs group was obviously longer and the median disease progression time (DPT) was shorter, exhibiting great differences with those in the Ctrl group (P < 0.05). Moreover, no great difference was observed in laboratory indicators between patients in various groups (P > 0.05). After treatment, the Obs group exhibited better levels in all indicators. Furthermore, the incidence of ARs in the Obs group was lower and exhibited a sharp difference with that in the Ctrl group (P < 0.05). CONCLUSION: SMTT had demonstrated good efficacy in patients with ALC, improving the DCR, enhancing the immune response of the body, and reducing the incidence of ARs, thereby promoting the disease outcome. Therefore, it was a treatment method worthy of promotion and application.

Reactive cutaneous capillary endothelial proliferation following camrelizumab monotherapy or combination therapy for multi-cancers: a large-scale pooled analysis of 10 studies in China.

Background: Skin toxicities are the most common adverse events related to immunotherapy, such as reactive cutaneous capillary endothelial proliferation (RCCEP) following treatment with the anti-programmed cell death-1 antibody camrelizumab. Objective: This study aimed to comprehensively analyze the clinical features and prognostic value of RCCEP in patients with malignancies who received camrelizumab alone (Camre) or in combination with the angiogenesis-targeted agent apatinib (Camre-Apa) or chemotherapy (Camre-Chemo). Design: A large-scale pooled analysis. Methods: Individual patient-level data were derived from 10 clinical trials of camrelizumab monotherapy, camrelizumab plus apatinib, or camrelizumab plus chemotherapy (n = 1305). Results: RCCEP occurred in 77.0% (516/670) of patients with Camre, 23.6% (70/296) with Camre-Apa, and 67.8% (230/339) with Camre-Chemo. Most RCCEP lesions were grade 1 or 2 in severity. The median time to onset was 0.8 months [interquartile range (IQR), 0.6-1.2] with Camre, 5.0 months (IQR, 2.7-8.0) with Camre-Apa, and 1.6 months (IQR, 1.0-4.2) with Camre-Chemo; and the median duration was 4.8 months (IQR, 2.6-8.8), 4.4 months (IQR, 1.7-8.9), and 7.2 months (IQR, 4.1-14.3), respectively. In all the three groups, patients with RCCEP showed significantly better clinical outcomes compared with those without [objective response rate: 23.8% versus 1.9% with Camre, 48.6% versus 21.2% with Camre-Apa, and 78.7% versus 54.1% with Camre-Chemo; median progression-free survival: 3.2 versus 1.7 months (hazard ratio (HR) = 0.36), 10.2 versus 4.5 months (HR = 0.39), and 12.7 versus 7.3 months (HR = 0.38); median overall survival: 13.3 versus 3.8 months (HR = 0.34), 29.2 versus 13.5 months (HR = 0.46), and not reached versus 12.8 months (HR = 0.19); all p < 0.0001]. Conclusion: Although RCCEP occurred frequently with camrelizumab, most lesions were mild and self-limiting. The occurrence of RCCEP was strongly associated with the antitumor activity and survival of camrelizumab, both as monotherapy and in combination therapy.

Impact of attaining aggressive vs. conservative PK/PD target on the clinical efficacy of beta-lactams for the treatment of Gram-negative infections in the critically ill patients: a systematic review and meta-analysis.

BACKGROUND: To perform a systematic review with meta-analysis with the dual intent of assessing the impact of attaining aggressive vs. conservative beta-lactams PK/PD target on the clinical efficacy for treating Gram-negative infections in critical patients, and of identifying predictive factors of failure in attaining aggressive PK/PD targets. METHODS: Two authors independently searched PubMed-MEDLINE and Scopus database from inception to 23rd December 2023, to retrieve studies comparing the impact of attaining aggressive vs. conservative PK/PD targets on clinical efficacy of beta-lactams. Independent predictive factors of failure in attaining aggressive PK/PD targets were also assessed. Aggressive PK/PD target was considered a100%fT>4xMIC, and clinical cure rate was selected as primary outcome. Meta-analysis was performed by pooling odds ratios (ORs) extrapolated from studies providing adjustment for confounders using a random-effects model with inverse variance method. RESULTS: A total of 20,364 articles were screened, and 21 observational studies were included in the meta-analysis (N = 4833; 2193 aggressive vs. 2640 conservative PK/PD target). Attaining aggressive PK/PD target was significantly associated with higher clinical cure rate (OR 1.69; 95% CI 1.15-2.49) and lower risk of beta-lactam resistance development (OR 0.06; 95% CI 0.01-0.29). Male gender, body mass index > 30 kg/m2, augmented renal clearance and MIC above the clinical breakpoint emerged as significant independent predictors of failure in attaining aggressive PK/PD targets, whereas prolonged/continuous infusion administration of beta-lactams resulted as protective factor. The risk of bias was moderate in 19 studies and severe in the other 2. CONCLUSIONS: Attaining aggressive beta-lactams PK/PD targets provided significant clinical benefits in critical patients. Our analysis could be useful to stratify patients at high-risk of failure in attaining aggressive PK/PD targets.

Clinical efficacy of acupuncture therapy combined with core muscle exercises in treating patients with chronic nonspecific low back pain: a systematic review and meta-analysis of randomized controlled trials.

Introduction: This meta-analysis aimed to determine the clinical efficacy of acupuncture combined with core muscle exercises on pain and functional status in patients with chronic nonspecific low back pain. Methods: This study followed the Preferred Reporting Items for Systematic Reviews and meta-analysis criteria for systematic reviews and meta-analyses. Randomized controlled trials published till November 2023 were searched in PubMed, Web of Science, Cochrane, Embase, China National Knowledge Infrastructure, Chinese Biomedical Literature, and Wanfang databases. The search strategy was related to disease type, intervention, and control measures and was structured around the search terms "low back pain," "acupuncture therapy," and "exercise." Two reviewers applied inclusion and exclusion criteria. Sensitivity and fixed effects analyses were performed to determine the primary outcomes. Results: We included 11 randomized controlled trials (n = 727) on acupuncture combined with core muscle exercises in patients with chronic nonspecific low back pain. Compared with controls, clinical efficacy was significant, with improvements in pain scores (visual analog pain scale and numerical rating scale) and Oswestry Disability Index in the intervention group. Discussion: Acupuncture therapy combined with core muscle exercises improved pain and functional status in patients with chronic nonspecific low back pain, with favorable clinical outcomes compared with single-core muscle training. Multicenter large-sample trials are required to obtain more reliable conclusions.

Percutaneous transforaminal endoscopic discectomy for lumbar disc herniation: an efficacy analysis.

OBJECTIVE: This retrospective study evaluated the clinical efficacy of percutaneous transforaminal endoscopic discectomy (PTED) in the treatment of lumbar disc herniation (LDH). METHODS: Data of 107 LDH patients admitted to the People's Hospital of Pingyang between July 2019 and May 2023 were analyzed retrospectively, including 51 cases treated with conventional open discectomy (control group) and 56 cases undergoing PTED (research group). We compared curative effects, operation time, intraoperative blood loss (IBL), incision length, time until ambulation, hospital stay, pre- and post-treatment pain intensity, lumbar function, and complications. Pain intensity was measured using the the Visual Analogue Scale (VAS), and the lumbar function was assessed by the Oswestry Disability Index (ODI). In addition, the factors influencing the efficacy in LDH patients were analyzed. RESULTS: The research group showed a statistically higher overall efficacy (P=0.034, χ2=4.479), longer operation time (P=0.002, t=3.114), less IBL (P<0.001, t=29.725), earlier ambulation (P<0.001, t=8.628), shorter hospital stay (P<0.001, t=8.628), and smaller incision length (P<0.001, t=15.948) than the control group. In addition, the postoperative VAS score (P<0.001, t=5.621) and ODI score (P<0.001, t=4.909) were reduced significantly after treatment and were lower in the research group than in the control group. The research group was also associated with a significantly lower overall complication rate (7.14% vs. 21.57%; P=0.032, χ2=4.608), including reduced incidence of lumbar spinal mobility limitation, incontinence, postoperative infection, and cauda equina syndrome. Furthermore, age, course of disease, and treatment method were strongly associated with the treatment efficacy in LDH patients. CONCLUSIONS: PTED is more effective than conventional open discectomy for LDH treatment. It reduces IBL, shortens incision length, facilitates patient recovery, alleviates postoperative pain, improves lumbar function, and minimizes the risk of postoperative complications.

Endometrial Receptivity Array (ERA) Test in a 32-Year-Old Female With Refractory Infertility: A Case Report.

We report a successful case for the clinical efficacy of the endometrial receptivity array (ERA) test for a 32-year-old female patient with refractory infertility. After our careful treatment, the patient gave birth to a male baby (3390 g) in November 2021. To our knowledge, though the clinical efficacy of the ERA test is controversial until March 2024, we think that the age of the patients, the number of IVF cycles, and the racial differences may have an impact on the clinical efficacy of the ERA test.

Apatinib beyond first progression is associated with prolonged overall survival in patients with advanced breast cancer: Results from an observational study.

In the present study, the efficacy and safety of a low dose of apatinib in the treatment of patients with advanced breast cancer (ABC) in a real-world setting were assessed, the impact of continuous anti-angiogenic therapy beyond progression was determined and the factors associated with efficacy were evaluated. A total of 63 patients with ABC who were treated with apatinib and for whom several lines of treatment had failed were retrospectively analyzed in Tangshan People's Hospital (Tangshan, China) between January 2016 and October 2022. Apatinib was administered orally combined with chemotherapy, endocrine therapy, targeted therapy or monotherapy at a dose of 250 mg per day. Apatinib administration was continued in certain patients beyond first progressive disease (PD), and these patients were defined as the continued anti-angiogenic treatment beyond first progression (CABF) group, while those who discontinued apatinib were defined as the non-CABF group. In the evaluation of the first efficacy, the objective response rate was 33.3%. A total of 26 patients continued to receive apatinib post-first PD and were allocated to the CABF group. The median overall survival (OS) time of the 63 patients was 16 months. Log-rank univariate analysis revealed that the OS time was significantly associated with molecular subtype (P=0.014), CABF (P=0.004), and the neutrophil-to-lymphocyte ratio (NLR) (P=0.011). Multivariate Cox regression analysis revealed that being in the non-CABF group and a high NLR were independent risk factors for lower OS time (P=0.017 and P=0.041, respectively). These results support the continued administration of low-dose apatinib beyond progression and the use of NLR as an easily accessible prognostic marker in patients with ABC treated with apatinib.

The frictional energy absorber effectiveness and its impact on the pressure ulcer prevention performance of multilayer dressings.

Pressure ulcers including heel ulcers remain a global healthcare concern. This study comprehensively evaluates the biomechanical effectiveness of the market-popular ALLEVYN® LIFE multilayer dressing in preventing heel ulcers. It focuses on the contribution of the frictional sliding occurring between the non-bonded, fully independent layers of this dressing type when the dressing is protecting the body from friction and shear. The layer-on-layer sliding phenomenon, which this dressing design enables, named here the frictional energy absorber effectiveness (FEAE), absorbs approximately 30%-45% of the mechanical energy resulting from the foot weight, friction and shear acting to distort soft tissues in a supine position, thereby reducing the risk of heel ulcers. Introducing the novel theoretical FEAE formulation, new laboratory methods to quantify the FEAE and a review of relevant clinical studies, this research underlines the importance of the FEAE in protecting the heels of at-risk patients. The work builds on a decade of research published by our group in analysing and evaluating dressing designs for pressure ulcer prevention and will be useful for clinicians, manufacturers, regulators and reimbursing bodies in assessing the effectiveness of dressings indicated or considered for prophylactic use.

The Effect of Unintended Facet Arthrodesis on the Treatment Outcome of Dynamic Neutralization System for Lumbar Degenerative Diseases.

Purpose: This study aimed to examine the influence of unintended facet arthrodesis on the therapeutic effectiveness of the dynamic neutralization system (Dynesys). Methods: This retrospective study enrolled consecutive patients who underwent posterior decompression and dynamic stabilization for lumbar spondylosis or spinal stenosis. Follow-up assessments included lumbar radiography, lumbar vertebral computerized tomography (CT), visual analog scale (VAS), and Oswestry disability index (ODI). Patients were classified into the facet fusion and non-fusion groups. The differences in the VAS scores for back pain and leg pain, ODI, intervertebral range of motion (ROM) at the surgical segments, and upper adjacent segments were assessed before and after treatment. Results: A total of 49 patients (29 males and 20 females) aged 31-65 years were enrolled and followed-up for over 40 months. Among the patients, 16 (32.7%) experienced unintended facet arthrodesis and were assigned to the fusion group, whereas the remaining patients were assigned to the non-fusion group. There was a significant increase in the incidence of facet arthrodesis in the surgical segments over time post-surgery (χ2 = 6.2, p < 0.05). The ROM of the surgical and upper adjacent segments, VAS scores for back pain and leg pain, and ODI were all significantly different before and after the operation (p < 0.05), but not between the fusion and non-fusion groups (p > 0.05). Conclusion: Although unintended facet arthrodesis is common after Dynesys procedure, the presence of facet arthrodesis does not significantly affect the efficacy of Dynesys in treating lumbar degenerative diseases.

Progress in the treatment of advanced hepatocellular carcinoma with immune combination therapy.

Advanced hepatocellular carcinoma (HCC) is a severe malignancy that poses a serious threat to human health. Owing to challenges in early diagnosis, most patients lose the opportunity for radical treatment when diagnosed. Nonetheless, recent advancements in cancer immunotherapy provide new directions for the treatment of HCC. For instance, monoclonal antibodies against immune checkpoint inhibitors (ICIs) such as programmed cell death protein 1/death ligand-1 inhibitors and cytotoxic t-lymphocyte associated antigen-4 significantly improved the prognosis of patients with HCC. However, tumor cells can evade the immune system through various mechanisms. With the rapid development of genetic engineering and molecular biology, various new immunotherapies have been used to treat HCC, including ICIs, chimeric antigen receptor T cells, engineered cytokines, and certain cancer vaccines. This review summarizes the current status, research progress, and future directions of different immunotherapy strategies in the treatment of HCC.

[Estimation of gammaaminobutyric acid intake from the human diet].

Gamma-aminobutyric acid (GABA) is an endogenous bioactive compound with essential properties for the normal functioning of the human nervous system. As a potent neurotransmitter, it plays an important role in modulating synaptic transmission by exerting phasic inhibition of neurons. This and other effects of GABA provide the phenomenon of neural tissue plasticity underlying learning, memory, maturation and repair of neural tissue after damage. It also has a wide range of biological actions, including antihypertensive, anti-diabetic, antioxidant, and anti-inflammatory. In this regard, GABA is increasingly used in the composition of food for special dietary uses and dietary supplements. However, its adequate intake levels have not yet been assessed and its dietary intake has not been characterized. The aim of the review was to estimate the level of GABA intake under balanced consumption of foods, corresponding to rational norms that meet modern requirements of a healthy diet. Material and methods. The existing literature on the problem in recent years was reviewed using the databases RISC, CyberLeninka, Pubmed, and ResearchGate. Results. Based on the analysis of scientific literature, we evaluated the content of GABA in the average daily diet, compiled on the basis of the rational norms of food consumption that meet modern requirements for healthy nutrition (Order of the Ministry of Healthcare of the Russian Federation dated August 19, 2016. No. 614). The balanced diet can provide about 740 mg of GABA per day, mainly due to vegetables (potatoes - 419 mg/day, beet - 49 mg/day, pumpkin - 41 mg/day), fruits (apple - 15 mg/day, grapes - 3.8 mg/day), as well as low-fat dairy products (92 mg/day). Conclusion. The presented data may be useful in assessing the adequacy of enrichment of foods for special dietary uses and dietary supplements with GABA.

Effectiveness of PD1/PD-L1 combined with anti-angiogenic drugs in patients with advanced nonsmall cell lung cancer: A systematic review and meta-analysis.

Background: Protein-1 (PD-1) and programmed cell death 1 ligand 1 (PD-L1) therapy have become an important treatment approach for patients with advanced nonsmall cell lung cancer (NSCLC), but primary or secondary resistance remains a challenge for some patients. PD-1/PD-L1 combined with anti-angiogenic drugs (AAs) in NSCLC patients have potential synergistic effects, and the survival benefit may vary based on a treatment order. To investigate the efficacy of PD-1/PD-L1 combined with AAs as the treatment for patients with advanced NSCLC. Materials and Methods: We comprehensively searched EMBASE, PubMed, Web of Science, CNKI, VIP, and Wanfang databases from January 2017 to September 2022. The Cochrane risk bias tool evaluated the quality of included randomized clinical trials. Newcastle-Ottawa-Scale score was used to evaluate the quality of retrospective studies. Publication bias was evaluated by funnel plot, Begg's test, and Egger's test. Results: Seventeen articles were finally selected, involving 5182 patients. Meta-analysis results showed that PD1/PD-L1 combined with AAs therapy significantly improved progression-free survival (PFS) (hazard ratio [HR] = 0.61, 95% confidence interval [CI]: 0.50-0.75, P < 0.00001), overall survival (OS) (HR = 0.79, 95% CI: 0.71-0.88, P < 0.00001), and objective response rate (ORR) (risk ratio = 0.88, 95% CI: 0.81-0.96, P = 0.004), with the statistically significant difference. The sensitivity analysis demonstrated the robustness of the PFS, ORR, and OS. Conclusion: The combination of PD-1/PD-L1 inhibitors with AAs in treating advanced patients has exhibited notable therapeutic advantages when contrasted with monotherapy. Specifically, the administration of PD-1/PD-L1 inhibitors in conjunction with AAs, or sequential treatment involving PD-1/PD-L1 followed by AAs, has shown enhanced therapeutic efficacy in this patient population.

The influence of anterior cervical discectomy and fusion surgery on cervical muscles and the correlation between related muscle changes and surgical efficacy.

BACKGROUND: Anterior cervical discectomy and fusion surgery (ACDF) is a common technique in treating degenerative cervical spondylosis. This study is to evaluate the changes of cervical muscles after ACDF and analyze the correlation between related muscle changes and clinical efficacy. METHODS: Sixty-five postoperative patients (single-level ACDF) with cervical spondylotic myelopathy from January 2013 to December 2022 were analyzed. The measured parameters include: the axial section of longus colli cross-sectional area (AxCSA), the volume of cervical longus, the ratio of long and short diameter line (RLS), the cervical extensor cross-sectional area (CESA), the vertebral body area (VBA), and the CESA/VBA. The visual analog scale (VAS), modified Japanese Orthopedic Association score (mJOA), and neck disability index (NDI) were evaluated. The changes in muscle morphology were analyzed, and the correlation analysis was conducted between morphological changes and function scores. RESULTS: The postoperative AxCSA of surgical segment (3rd month, 12th month, and the last follow-up) was decreased compared to preoperative (141.62 ± 19.78), and the differences were significant (P < 0.05). The corresponding data reduced to (119.42 ± 20.08) mm2, (117.59 ± 19.69) mm2, and (117.41 ± 19.19) mm2, respectively (P < 0.05). The RLS increased, and the volume of cervical longus decreased significantly after surgery (P < 0.05). Negative correlation was found between postoperative volume of cervical longus and VAS at the 3rd month (r = - 0.412), 12th month (r = - 0.272), and last follow-up (r = - 0.391) (P < 0.05). Negative correlation existed between postoperative volume of cervical longus and NDI at the 3rd month (r = - 0.552), 12th month (r = - 0.293), and last follow-up (r = - 0.459) (P < 0.05). CONCLUSION: The volume of cervical longus decreased and its morphology changed after ACDF surgery. The mainly affected muscle was the cervical longus closing to the surgical segment. Negative correlation was found between the postoperative volume of cervical longus and function scores (VAS and NDI).
