Cardiopulmonary effects of prolonged surgical abdominal retractors application during general anesthesia: a prospective observational comparative study

Abstract Introduction: Increasing abdominal pressures could affect pulmonary compliance and cardiac performance, a fact based on which the aim of the present study to detect the cardiopulmonary burden of multiple retractors application during supine versus lateral abdominal surgeries. We hypothesized that surgical ring multiple retractors application would affect the pulmonary and cardiac functions during both lateral and supine abdominal surgeries. Methods: Prospective observational comparative study on forty surgical patients subdivided into two groups twenty each, comparing pulmonary compliance and cardiac performance before, during and after retractors application, group (S) supine position cystectomy surgery, and group (L) lateral position nephrectomy surgery under general anesthesia, Composite 1ry outcome; dynamic compliance C-dyn and cardiac index CI and Other outcome variables ICON cardio-meter were also recorded. Results: C-dyn and C-stat were significantly decreased late during retractor application in lateral compared to supine surgery with significant decrease compared to basal values all over the surgical time. CI was significantly increased after retractor removal in both of the study groups compared to basal values. PAW P was significantly increased in -lateral compared to supine surgery -with significant increase compared to basal value all over the surgical time in both of the study groups. significant increase in DO2I compared to basal value during both supine and lateral positions. Conclusion: Surgical retraction results in a short-lived significant decreases in lung compliance and cardiac output particularly during the lateral-kidney position than the supine position compliance.

Vibration sensation associated with motor function has specific frequency characteristics in community-dwelling older Japanese adults / 体力科学

Vibration sensation is related to motor function. However, it is unclear which vibration frequencies are associated with motor function. Therefore, in this cross-sectional study, we investigated whether a specific frequency of vibration sensation could explain motor functions. Thirty-two community-dwelling Japanese healthy older adults aged 70 years or older participated in the present study. Grip strength, one-leg standing time, and 10-m walking time were evaluated as indicators of motor function. Vibratory (40, 128, and 256 Hz) and tactile sensory tests were examined as sensory functions. Grip strength per body weight was significantly correlated with sex, body mass index, falls efficacy scale, vibration sensation with 40 and 128 Hz, and 10-m walking time (P < 0.05). Furthermore, one-leg standing time showed a correlation between vibration sensation (128 and 256 Hz) and fall history (P < 0.05). However, 10-m walking time was significantly correlated with only the grip strength to body weight ratio. Multiple regression analysis showed that vibration sensation with 128 Hz (β = 0.427) and sex (β = -0.335) (P < 0.05) were significant independent variables associated with grip strength to body weight ratio. Vibration sensation with 256 Hz (β = 0.465) and age (β = -0.343) (P < 0.05) were significant independent variable associated with one-leg standing time. No significant variables were identified for the 10-m walking time. Vibration sensation associated with motor function shows specific frequency characteristics in community-dwelling older Japanese adults.

Research status and progress on limb preservation technology / 器官移植

Limb replantation and transplantation is the optimal treatment for traumatic limb amputation. Safe and effective limb preservation is the key factor to determine the success of limb replantation and transplantation. Currently, static cold storage is the gold standard of limb preservation. However, the preservation time is short, which may no longer meet clinical requirements. With rapid development of organ preservation in recent years, novel preservation technologies, such as ultra-low temperature preservation, supercooling preservation and mechanical perfusion preservation, have successively emerged. However, at present, these techniques are primarily applied to the preservation of solid organs rather than composite tissue allografts with blood vessels including limbs. In this article, research status and progress on the application of static cold storage and mechanical perfusion preservation in limb preservation were reviewed, aiming to provide reference for clinical application of limb preservation technology and promote the development of limb replantation and transplantation.

Liver graft preservation and functional maintenance accelerate the development of liver transplantation / 器官移植

As an effective treatment for end-stage liver disease, liver transplantation has been widely carried out worldwide and gradually captivated widespread recognition. With the advancement of liver transplantation techniques, the incidence of postoperative complications has been gradually declined, and the short-term and long-term prognosis of recipients have been constantly improved. However, a huge gap has existed between the supply and demand of donor organs, which is a major factors restricting the development of liver transplantation. The amount of liver transplantation operation in China is increasing year by year, the shortage of donor liver is becoming more and more prominent, and marginal donor liver is increasingly used in clinic. In recent years, the selection criteria of donor organs, organ preservation and functional maintenance have been continuously improved. In this article, the application and development trend of different techniques were reviewed from the perspectives of donor liver preservation and functional maintenance, and recent technical development and research results were summarized, aiming to provide reference for further enhancing the survival rate of grafts and recipients and promoting the development of liver transplantation in China.

Effect of hypothermic machine perfusion on expression levels of inflammatory cytokines in rat kidney / 器官移植

Objective To evaluate the effect of hypothermic machine perfusion (HMP) on the expression levels of inflammatory cytokines in rat kidney. Methods Thirty male rats were randomly divided into the control (Control group), static cold storage group (SCS group) and HMP group, with 10 rats in each group. The velocity, intrarenal resistance and pH value of perfusion effluent were recorded during HMP. The expression levels of CXC chemokine ligand (CXCL)1, CXCL2, interferon (IFN)-β1, IFN-α4, CC chemokine ligand (CCL)2, CCL20, interleukin (IL)-17α, IL-17C and tumor necrosis factor (TNF)-α messenger RNA (mRNA) in renal tissues were evaluated by reverse transcription polymerase chain reaction (RT-PCR). Pathological changes of the kidney were observed by hematoxylin-eosin (HE) staining. Results During HMP, the velocity and intrarenal resistance remained stable, and the pH value of perfusion effluent was decreased slowly. RT-PCR showed that the relative expression levels of CXCL1, CXCL2, CCL2, CCL20, IL-17α, IL-17C and TNF-α mRNA in the SCS and HMP groups were higher compared with those in the Control group. Compared with the SCS group, the relative expression levels of CXCL1, CXCL2, CCL2, CCL20, IL-17α and TNF-α mRNA were up-regulated in the HMP group (all P<0.05). HE staining revealed that the morphology of renal cells was normal in the Control group, whereas evident epithelial necrosis, cytoplasmic vacuolation, brush border loss and epithelial shedding were observed in the SCS group. Compared with the SCS group, pathological changes in the HMP group were alleviated. Conclusions HMP may activate renal inflammation, and inhibiting the activation of inflammation during HMP is expected to further improve the effect of allograft preservation.

A Case of Laryngeal Venous Malformation Successfully Treated with Keishibukuryogan and Daiokanzoto / 日本東洋医学雑誌

Laryngeal venous malformation has a risk of airway obstruction due to its enlargement or bleeding. It requires treatment such as sclerotherapy, laser treatment or surgery. However, adult-type laryngeal venous malformation occurs frequently in the upper part of the glottis, and causes almost no symptoms except when it occurs in the vocal cords. So some patients do not wish to undergo surgery. This time, we describe a case of an asymptomatic laryngeal venous malformation patient who did not wish to receive laser treatment, and was significantly improved by Kampo medicine. The patient was a 69-year-old man. He consulted us because of an accidental laryngeal mass on upper gastrointestinal endoscopy during a medical examination, but he had no particular pharyngeal symptoms. A venous malformation was found in the upper part of the right glottis, and we recommended him laser treatment. But he did not wish it because he had no symptoms. We considered the condition of static blood (oketsu), and administered keishibukuryogan for 7 weeks, but there was no change. Since he had constipation, we administered daiokanzoto together with keishibukuryogan, and his bowel movement improved. Thirteen weeks after the beginning of the combined use, the venous malformation also remarkably reduced.

Effect of couch rotation angle on non-coplanar static intensity-modulated radiotherapy plan for gastric cancer / 中国辐射卫生

Objective To investigate the effect of couch rotation angle on non-coplanar static intensity-modulated radiotherapy (IMRT) plan for gastric cancer and to provide a reference for clinical planning. Methods A retrospective analysis was conducted on patients who recently underwent postoperative IMRT for gastric cancer. Twenty patients who received radiotherapy in the centre of Radiation Oncology of Huanggang Central Hospital from August 2022 to January 2023 were selected. That were selected to receive a seven-field coplanar static IMRT plan based on a couch rotation angle of 0° as the control group. Then, based on the coplanar IMRT plan, only the couch rotation angle of gantry angles 30° and 330° was changed to 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, and 90°, respectively, and nine different non-coplanar plans were established. The homogeneity index (HI), conformity index (CI) of the target volume, and monitor unit (MU), as well as Dmean, V20, and V30 of the left and right kidneys, Dmax, Dmean, V10, V20, and V30 of the spinal cord, and Dmax, Dmean, V10, V20, V30, and V40 of the small intestine and liver were compared among the 10 plans. The MU and the dosimetric parameters of the target volumes and When the couch rotation angle was 60°, the minimum HI and maximum CI of the target volume were 0.0714±0.0089 and 0.9271±0.0108, respectively, and the minimum MU was 438±26, with the best homogeneity and conformity in the target volume and the shortest machine treatment time (P＜0.05). When the couch rotation angle was 10°, the Dmax of the small intestine was lowest, being (4620.73±99.27) cGy. When the couch rotation angle was 60°, the Dmean of the left and right kidneys was lowest, being (1246.30±130.35) cGy and (1001.52±103.33) cGy, respectively; the V20 of the left and right kidneys was lowest, being 22.87±6.29 and 19.69±1.84, respectively; the V10 and V30 of the spinal cord were lowest, being 40.08±4.92 and 1.68±0.34, respectively (P＜0.05). Conclusion The couch rotation angle has some influence on the postoperative treatment planning for patients with gastric cancer. In the design of non-coplanar plan for gastric cancer, the couch rotation angle of 60° contributes to establishing a better radiotherapy plan.

Research status of machine perfusion of heart / 器官移植

High-quality donor heart is the prerequisite and fundamental guarantee for successful heart transplantation. Reasonable donor heart preservation technique plays a key role in improving the quality of donor heart and the prognosis of heart transplantation. Static cold storage (SCS) is currently the standard preservation technique for cardiac allograft. However, it is prone to cause severe cold ischemia injury to the donor heart, and it is impossible to evaluate heart function during SCS. As an important emerging technique of organ preservation, machine perfusion better matches with physiological conditions compared with SCS, which may remove metabolic wastes and provide basic substances for metabolic needs during organ preservation, prolong the preservation time and improve the preservation effect to a certain extent. Besides, it may also effectively evaluate organ function and improve clinical prognosis of heart transplantation. Meantime, it can also repair organ damage, significantly optimize organ quality and improve the utilization rate of donor organs. In this article, research status of machine perfusion of donor heart was reviewed.

Development status and new challenges of heart transplantation / 器官移植

Heart transplantation is the primary therapeutic option for patients with end-stage heart failure. The shortage of donors has been the main limiting factor for the increasing quantity of heart transplantation. With persistent updating and introduction of novel technologies, the donor pool has been increasingly expanded, such as using the heart from older donors, donors infected with hepatitis C virus, donors dying from drug overdose or donation after cardiac death (DCD) donors, etc. Meantime, the proportion of recipients with advanced age, multiple organ dysfunction, mechanical circulatory support and human leukocyte antigen antibody sensitization has been significantly increased in recent years. The shortage of donors, complication of recipients' conditions, individualized management of immunosuppressive therapy and prevention and treatment of long-term cardiac allograft vasculopathy are all challenges in the field of heart transplantation. In this article, novel progresses on donor pool expansion, improving the quality of recipients, strengthening the diagnosis and treatment of rejection, and preventing cardiac allograft vasculopathy were reviewed, aiming to prolong the survival and enhance the quality of life of patients with end-stage heart failure on the waiting list or underwent heart transplantation.

Do static and dynamic pupillary parameters differ according to childhood, adulthood, and old age? A quantitative study in healthy volunteers

Purpose: We aimed to evaluate the normative pupillometry values and mean pupil dilatation speed in healthy individuals in different age groups in our study. Methods: The study group included 180 eyes of 90 healthy volunteers in different age groups. Group 1 consisted of 30 participants between the ages of 6 and 18, group 2 consisted of 30 participants aged 19–40, and group 3 consisted of 30 participants aged 41–75. Scotopic, mesopic, photopic, and dynamic measurements were taken with automatic pupillometry of Sirius Topographer (CSO, Firenze, Italy). The mean pupil dilation speed at the 18th second was calculated according to dynamic measurements. Results: Group 1 had a significantly larger pupil diameter than groups 2 and 3 in all static and dynamic parameters, and the mean pupil dilation speed was the highest among the groups (P < 0.001 for all static and dynamic parameters). In addition, group 2 had a significantly larger pupil diameter than group 3 (P < 0.001 for all static and dynamic parameters) and the mean pupil dilation speed was faster than group 3 (P = 0.027). Conclusion: We have presented the static and dynamic parameters and the mean speed of pupil dilatation at the 18th second with automatic pupillometry in healthy individuals in childhood, adulthood, and old age. More studies with higher participants and younger age children are needed.

Muscle pain induced by static contraction is modulated by transient receptor potential vanilloid 1 and ankyrin 1 receptors

Abstract Molecular mechanisms involved in the development of muscle pain induced by static contraction are not completely elucidated. This study aimed to evaluate the involvement of the transient receptor potential vanilloid 1 (TRPV1) and the transient receptor potential ankyrin 1 (TRPA1) receptors expressed in peripheral and central terminals of primary afferents projected to gastrocnemius muscle and spinal cord in muscle pain induced by static contraction. An electrical stimulator provided the contraction of rat gastrocnemius muscle and mechanical muscle hyperalgesia was quantified through the pressure analgesimeter Randall-Selitto. AMG9810 and HC030031 were used. When administered in ipsilateral, but not contralateral gastrocnemius muscle, drugs prevented mechanical muscle hyperalgesia induced by static contraction. Similar results were obtained by intrathecal administrations. We propose that, in an inflammatory muscle pain, peripheral and central TRPV1 and TRPA1 work together to sensitize nociceptive afferent fibers, and that TRPV1 and TRPA1 receptors are potential target to control inflammatory muscle pain.

Relationship between physical activity level and balance in middle-aged and older women / Relação entre o nível de atividade física e equilíbrio em mulheres na meia-idade e idosas

Abstract Introduction: Physical exercise may improve motor skills, such as static standing balance. However, the association between physical activity level based on activities of daily living and static balance is unknown. Objective: To assess the association between the physical activity level and static balance in middle-aged and older women. Methods: This cross-sectional study involved 589 community-dwelling women. Static balance was assessed using the single-leg stance test (SLST) with eyes open and closed. Physical activity level was assessed using the International Physical Activity Questionnaire Short Form and classified as high, moderate, or low. Kruskal-Wallis test compared balance performance between participants with different physical activity levels. Multiple quantile regression analyses assessed the association between variables adjusted for age, family income, educational level, body mass index, comorbidities, and parity. Results: Participants with low physical activity level showed worse SLST performance with eyes open and closed than participants with high physical activity level in the bivariate analysis. However, physical activity level and SLST performance were not associated in the analysis adjusted for covariates. Conclusion: Our results suggested that only being active in daily living activities is not associated with better standing balance in middle-aged and older women. Specific physical exercise programs should be implemented to improve balance in this population.

Resumo Introdução: O exercício físico pode melhorar as habilidades motoras, como o equilíbrio estático na posição ortostática; no entanto, a associação do nível de atividade física durante as atividades de vida diária e o equilíbrio estático não é conhecida. Objetivo: Avaliar a associação entre o nível de atividade física e o equilíbrio estático em mulheres de meia-idade e idosas. Métodos: Trata-se de um estudo transversal com 589 mulheres residentes na comunidade. O equilíbrio estático foi avaliado usando o teste de equilíbrio unipodal com os olhos abertos e fechados. O nível de atividade física foi avaliado usando o Questionário Internacional de Atividade Física - versão curta e classificado em alto, moderado e baixo. O teste de Kruskall Wallis comparou o desempenho no teste de equilíbrio unipodal de participantes com diferentes níveis de atividade física. Modelos de regressão quantílica avaliaram a associação entre as variáveis ajustada pelas covariáveis idade, renda familiar, escolaridade, índice de massa corporal, condições crônicas e paridade. Resultados: Na análise bivariada, as mulheres com baixo nível de atividade física mantiveram o equilíbrio em pé com os olhos abertos e fechados por um tempo menor do que aquelas classificadas como alto nível de atividade física. No entanto a associação entre nível de atividade física e performance no teste de equilíbrio estático não foi significativa na análise ajustada para as covariáveis. Conclusão: Os resultados sugerem que apenas ser ativa nas atividades de vida diária não está associado a um melhor equilíbrio em mulheres de meia-idade e idosas. Programas específicos de exercício físico devem ser implementados visando um melhor desempenho do equilíbrio nesta população.

Comparative Analysis on Two Different Algorithms for Estimating Muscle Forces / 医用生物力学

Objective To explore the differences between the result of static optimization (SO) and computational muscle control (CMC) algorithms for estimating muscle forces, so as to provide references for researchers to choose the appropriate algorithm and make horizontal comparison of the results from different studies. Methods Targeting at a single gait cycle running at four different speeds, SO and CMC algorithms were used to calculate forces and activations of the major muscles in lower limbs, and the results were compared and analyzed. Results Among the 10 major muscles participating in running, except for anterior tibial and rectus femoris, muscle forces and muscle activations solved by the two algorithms had similar curves with correlation coefficients more than 0.91, and the peak value of muscle forces solved by SO was higher and the positions of peak muscle activation had a 10 ms delay. Conclusions In movement analysis, if the research focuses on the timing of muscle forces and the contribution ratios among different muscles, there is not too big difference and SO algorithm is recommended for its simplicity and efficiency. For horizontal comparison of muscle forces and muscle activations estimated by SO and CMC algorithms in different studies, the differences between the two algorithms should be considered.

Role of early dynamic PET/CT scan imaging with 18F-PSMA-1007 in staging and restaging prostate cancer in a tertiary private hospital

Introduction@#18F-PSMA-1007 is a novel prostate-specific membrane antigen (PSMA)-based radiopharmaceutical for imaging prostate cancer. The recommended imaging time is 60 minutes post-injection of the radiotracer. However, during this time there is a physiologic accumulation of the radiotracer in the urinary bladder which sometimes may obscure lesions adjacent to it. @*Objective@#This study aims to determine if early dynamic imaging in addition to the recommended 60-minute postinjection static imaging can improve the detection of PSMA-avid lesions in the staging and restaging of prostate cancer. @*Methods@#This is a retrospective cross-sectional study of the detection rate of early dynamic and static imaging using 18F-PSMA-1007 PET/CT scan in patients with prostate cancer (PCa) who were referred for initial staging or restaging. The McNemar test was used to compare the detection rate between the two imaging. Spearman correlation was used to determine the correlation of Gleason score (GS), PSA, and SUVmax values.@*Results@#18F-PSMA-1007 PET/CT scans of 53 patients with prostate cancer, were referred for either staging (22/53) or restaging (31/53), all of whom had undergone both early dynamic and static imaging. Among the 53 patients, 5 had 2 lesions each, for a total of 58 lesions were included in the analysis. There were 48/58 lesions detected on both early dynamic and static imaging, 2/58 lesions were only detected in the early imaging, 1/58 lesions was only detected in the static imaging, and 7/58 were not detected on both imaging. McNemar the test was not statistically significant (p = 1.000) in the detection rate of the two methods. There is a positive correlation between serum PSA levels and SUVmax measurements for all the patients. Only the correlation between the GS and SUVmax in the static imaging of the staging group was statistically significant. @*Conclusion@#Early dynamic imaging may be an adjunctive procedure in detecting PSMA-avid lesions, particularly in the basal segment of the prostate gland near the urinary bladder. However, it is not recommended as a standard component of the comprehensive protocol for imaging using 18F-PSMA-1007 PET/CT in patients with PCa.

Static balance and limits of stability in patients with cervical vertigo / 中国康复理论与实践

@#Objective To analyze the characteristics of static balance and limits of stability (LOS) in patients with cervical vertigo (CV). Methods From January, 2020 to August, 2021, 30 CV patients in our hospital (vertigo group) and 30 healthy people (control group) were selected and tested with PRO-KIN system, under the conditions of eyes open and closed. The standard deviation of the vertical and horizontal amplitude, the mean of vertical and horizontal sway velocities, the area of the movement, the length of the movement, and LOS at eight directions, The Romberg ratios of the area and the length were caculated. Results All the indicators of the static balance were higher under eyes closed than under eyes open in both groups (|Z| > 2.138, P < 0.05); whether under the eyes open or closed, the static balance indicators were higher in the vertigo group than in the control group (|Z| > 2.004, P < 0.05), except for the mean of horizontal sway velocities (|Z| < 1.026, P > 0.05). The LOS and total LOS completion percentage in the front (upper right, right above, upper left) were lower in the vertigo group than in the control group (|Z| > 2.240, P < 0.05). Conclusion The static balance abilities decrease for CV patients, and the balance control depends on visual compensation. The range of LOS reduces, means a higher risk of falling.

Evaluation Method of Static Balance Ability Based on Human Pelvic Center Measurement / 中国医疗器械杂志

This study evaluates the static balance ability of human body based on lower limb rehabilitation robot.According to the balance parameters obtained from the movement trajectory of the center of human pelvis, SPSS statistical software was used to verify that there was significant difference between the two groups (P<0.01). Principal component analysis is used to allocate the weight of each parameter and establish the comprehensive evaluation value. The comprehensive evaluation value of the control group was 0.383±0.038, and the experimental group was 0.875±0.136. When the subject's comprehensive evaluation value is between 0.739 and 1.011, it indicates the presence of balance dysfunction, and when it is between 0.345~0.421, it indicates that the balance of the lower limbs of the subject is normal. Experimental results show that this evaluation method can objectively and quantitatively reflect the static equilibrium state of human body.

Normothermic machine perfusion of kidney and ischemia-free kidney transplantation / 器官移植

To increase the utilization rate of expanded criteria donor (ECD) kidney, the kidney preservation methods have been ever advancing in recent years. The application of normothermic machine perfusion (NMP) promotes the preservation, evaluation and repair of ex vivo donor kidneys and accelerates the innovation of surgical approaches of kidney transplantation. Ischemia-free kidney transplantation (IFKT), which initiated by Organ Transplantation Center of the First Affiliated Hospital of Sun Yat-sen University, keeps the blood flow and oxygen supply of the donor kidney with NMP machine during the entire process of acquisition, preservation and transplantation, thereby fundamentally avoiding ischemia-reperfusion injury (IRI) of the donor kidney and reducing the risk of delayed graft function (DGF) and acute rejection after surgery. In this article, recent progresses upon the kidney NMP, surgical procedures and short-term outcomes of IFKT were reviewed, aiming to provide reference for enhancing the utilization rate of ECD donor kidney and resolving the issue of organ shortage.
