RESUMEN
Prevention and treatment of complications after liver transplantation play a significant role in maintaining liver graft function and improving clinical prognosis of the recipients. Neutrophil extracellular trap (NET) are fibrous net-like structures composed of DNA as the skeleton and histones and granular proteins released by activated neutrophils. Studies have shown that the activation of neutrophils and the release of NET in donor liver after liver transplantation are involved in the incidence of multiple liver transplantation-related complications including ischemia-reperfusion injury, acute rejection, acute liver failure and recurrence of hepatocellular carcinoma, etc. In this article, the effect of NET on the complications after liver transplantation was mainly assessed, and research progress on NET as a potential target for the prevention and treatment of complications after liver transplantation was reviewed, aiming to provide reference for the prevention and treatment of complications after liver transplantation, enhance clinical efficacy of liver transplantation and improve clinical prognosis of the recipients.

OBJECTIVE@#To explore the effectiveness of hairpin shaped incision combined with cover-lifting flap in plastic surgery of huge fat pad on nape and back.@*METHODS@#Between March 2019 and March 2023, 10 patients with huge fat pad on the nape and back were treated. There was 1 male and 9 females with an average age of 52 years (range, 39-57 years). All patients had soft tissue bulge on the nape and back. Preoperative MRI showed the subcutaneous fat thickening. The length of the longitudinal axis of the fat pad ranged from 10.0 to 25.0 cm (mean, 14.1 cm), the length of the transverse axis ranged from 6.0 to 15.0 cm (mean, 10.8 cm); the thickness of the fat pad ranged from 2.5 to 5.1 cm (mean, 3.9 cm). Under general anesthesia, the patient was placed in a prone position and a hairpin shaped incision was made. The flap was lifted to remove the fat pad according to the marked area. The dressing was changed every 2 days after operation.@*RESULTS@#The operation time was 35-110 minutes (mean, 72 minutes). The intraoperative blood loss was 35-80 mL (mean, 49.5 mL). The drainage tube was removed at 2-5 days after operation (mean, 3.4 days). All incisions healed by first intention without incision dehiscence, infection, subcutaneous bruising, hematoma, or other related complications. All patients were followed up 2-24 months (mean, 12 months). All patients had a good shape of the nape and back and no noticeable scar on the incision. According to the Vancouver Scar Scale evaluation criteria, the incision scar score was 3-5 (mean, 3.7) at 2 months after operation. Patients had good neck movement with no recurrence.@*CONCLUSION@#For the huge fat pad on the nape and back, the plastic surgery using hairpin shaped incision and cover-lifting flap has the advantages of fully exposing the fat pad, concealed incision, simple operation, and natural shape of the nape and back after operation.

RESUMEN
Background: India accounts for a quarter of the world cervical cancer burden. Cervical cancer is highly preventable. However, low level of participating women in screening is one of the major issues. The aim of this work was to study the factors that influence women to participate in cervical cancer screening by providing menstrual pads for human papillomavirus (HPV) testing. Methods: Menstrual clothes were collected from two different populations from the rural areas of Maharashtra state for HPV testing to screen for cervical cancer. For this study, out of 945 participated women, 557 (58.9%) provided their menstrual pads. Multivariate logistic regression was applied to calculate the odds ratio (OR) and 95% confidence interval (95% CI). Results: The probability of providing the menstrual pads was high among the women who were highly educated compared to those with less education (OR: 1.4; 95% CI: 1.0–1.9), having mobile phone facilities as compared to those with no mobile phones (OR: 1.4; 95% CI: 1.0–2.0), who were using new cloths as menstrual pads compared to those who did not use the same (OR: 8.5; 95% CI: 5.0–14.3), who did not have tobacco habit as compared to those who had tobacco habit (OR: 1.4; 95% CI: 1.1–1.9) and in the village where health worker was stationed as compared to the village where health worker was not stationed (OR: 1.8; 95% CI: 1.4–2.5). Conclusion: Factors including health worker availability, using mobile phones for communication and high education level facilitate women’s participation. To improve the participation, there is need to apply special strategies for older age group, less educated women and women having tobacco habit.

RESUMEN
Objective:To study the inter-fraction setup errors, intra-fraction movement of patients and its influence on dosimetry, position repeatability of the supraclavicular area, and the plastic stability of the vacuum cushion and styrofoam when one of the three fixation method are applied in the clinical radiotherapy of breast cancer. The three fixation method include acuum negative pressure pad (VP), acuum negative pressure pad combined with a breast bracket (VB), and polyurethane styrofoam combined with a breast bracket (PB).Methods:A total of 96 breast cancer patients who received radiotherapy at Jiangsu Cancer Hospital during 2019-2021 were collected prospectively for study. They were randomly divided into three groups (VP, VB, and PB). Cone-Beam CT and a planning system were used to obtain inter-fraction setup errors, intra-fraction movement of patients and its influence on dosimetry, position repeatability of supraclavicular area, and the plastic stability of vacuum pad and polyurethane tyrofoam.Results:In the left-right (LR) direction, there were no statistical differences in the inter-fraction setup errors among the three groups. In the superior-inferior (SI) direction, inter-fraction setup errors of the PB group were smaller than those of the VB group (3.02 ± 2.04, 3.65 ± 2.64, t=2.35, P=0.031). In the anterior-posterior (AP) direction, the inter-fraction setup errors of both the VB and PB groups were smaller than those of the VP group (3.36 ± 2.93, 3.14 ± 0.98, 4.03 ± 2.55, t=2.29, 3.11, P< 0.05). In the AP direction, the intra-fraction movement of patients of the VP and PB groups were less than that of the VB group (1.31 ± 0.95, 1.24 ± 0.89, 1.88 ± 1.33, t=-2.04, -2.31, P< 0.05). Moreover, the intra-fraction movement of patients had no statistical effect on the dosimetric distribution ( P> 0.05), and the breast bracket did not improve the position repeatability of the supraclavicular region ( P>0.05). In addition, the plastic stability of polyurethane styrofoam was significantly better than that of the acuum negative pressure pad ( t=2.43-5.63, P< 0.05). Conclusions:The inter-fraction setup errors and intra-fraction movement of patients with breast cancer can be reduced by using PB. Compared to an acuum negative pressure pad, polyurethane styrofoam can keep plastic stability throughout the treatment of the patients.

Objective:To explore the setup errors of vacuum pad combined with breast bracket in linear accelerator intensity-modulated radiotherapy for breast cancer.Methods:The clinical data of 72 patients who received linear accelerator intensity-modulated radiotherapy after breast conserving surgery in Hai'an Hospital of Traditional Chinese Medicine from July 2017 to March 2022 were retrospectively analyzed. According to the radiotherapy fixation schemes, they were divided into vacuum pad group (24 patients), breast bracket group (27 patients) and vacuum pad combined with breast bracket group (21 patients). Cone-beam CT was used to analyze the setup errors of the fixation, and the mean value of the overall errors and the standard deviation of the system errors were calculated. The relative factors affecting the fixed setup errors were analyzed.Results:There were statistical differences among vacuum pad group, breast bracket group and vacuum pad combined with breast bracket group in the level of forward and backward (Z) direction translation error (2.11±0.41, 2.67±0.26 and 1.79±0.21) and Z direction rotation error (1.14±0.24, 1.05±0.21 and 0.91±0.22) ( F values were 45.86 and 6.21, both P < 0.05). The level of Z direction translation error in vacuum pad group was higher than that in vacuum pad combined with breast bracket group, and the difference was statistically significant ( t = 12.37, P = 0.001). The level of Z direction rotation error in breast bracket group was higher than that in vacuum pad combined with breast bracket group, and the difference was statistically significant ( t = 3.41, P = 0.001). In the breast bracket group, the planning target volume (PTV) extension boundary values in the left and right (X), up and down (Y), and Z directions were 2.02, 2.09 and 1.97; the PTV release boundary values in X, Y and Z directions of the vacuum pad group were 1.81, 2.07 and 2.25; the external boundary values of PTV in X, Y and Z directions of the vacuum pad combined with breast bracket group were 1.13, 1.51 and 1.49. The result of multifactor analysis showed that body mass index (BMI) ( OR = 4.208, 95% CI 1.438-12.312) and breast volume ( OR = 4.023, 95% CI 1.375-11.769) were the independent influencing factors of fixed setup errors (both P < 0.05). Conclusions:The application of vacuum pad combined with breast bracket in the fixed setup of linear accelerator intensity-modulated radiotherapy of breast cancer is helpful to reduce the fixed setup errors, but at the same time, the fixed setup errors is affected by the patient's BMI, breast volume and other factors.

RESUMEN
Background:In transfusion service,it is very important to carry out blood group with perfection. Blood grouping is a fast and easy way to ensure that you receive the right kind of blood for right patient.There are many methods we usefor blood grouping like Slide method,test tube method,column agglutination method anderythrocyte magnetic technique. Test tube method is gold standard method for blood grouping. We need to verify donor blood groupin blood bank or at camp site, for patients at bed side, at the time of issue of blood unit or at the time of dire emergency so to verifythe blood group in Blood centres we require the results of blood grouping urgently. ABD PAD® is a new device for the quick confirmation of the ABO blood group. Materials And Methods:In this Pilot study,200 samples were taken of which 100 were donor samples and 100 were patient samples. Blood grouping was performed on the ABD PAD, and results were compared with conventional tube technique and automate platform, Qwalys 3 (Diagast) EMT technique.Results:All 200 tests performed on the ABD PAD were concordant with other standard methods, namely the Test Tube technique and automated platform, Qwalys 3 (Diagast).The results of ABD PAD were quicker(within 30 seconds) and easy to interpret.Discussion:The manual confirmation of the ABO group and RH-rhesus is a repetitive and time consuming task. It requiresfollowing a procedure handling several reagents. In this context, the ABD pad is a ready to use device using the latex technology M-TRAP, facilitating the procedure intendedfor the confirmation of ABO/Rh. The only drawback is that we are not able to perform reverse grouping. Conclusion:ABD PAD is very useful for blood grouping in donors in the blood bank as well as in outdoor blood donation camp and at the time of issue of blood unit when we want to re-check the blood group of the issue bag. It is easy to interpret, fast, reliable and results are comparable with standard methods.
RESUMEN
Objective:To retrospectively analyze the setup errors of thermoplastic head and shoulder molds alone or combined with vacuum pad in hypofractionated stereotactic radiotherapy (HFSRT) for non-small cell lung cancer (NSCLC) with brain metastases.Methods:Fifty-four NSCLC patients with brain metastases who received HFSRT from 2017 to 2019 were enrolled in this study. Twenty-four patients were fixed with thermoplastic head and shoulder molds (group A), and 30 patients were fixed with thermoplastic head and shoulder molds plus vacuum pad (group B). The interfraction and intrafraction setup errors were acquired from cone-beam CT online image registration before and after the HFSRT. Optical surface system was applied in monitoring the intrafraction setup errors. The setup errors in each direction between two groups were analyzed by independent samples t-test. Results:For the interfraction setup errors of the whole group, the proportion of the horizontal setup errors of ≥3mm was 7.0% to 15.4% and 7.0% to 12.6% for the rotation setup errors of ≥2°. In group A, the anteroposterior setup error was (1.035±1.180)mm, significantly less than (1.512±0.955)mm in group B ( P=0.009). In group A, the sagittal rotation setup error was 0.665°±0.582°, significantly less than 0.921°±0.682° in group B ( P=0.021). For the intrafraction setup errors of the whole group, the proportion of horizontal setup errors of ≥1mm was 0% to 0.7%, whereas no rotation setup error of ≥1° were observed. In group B, bilateral, anteroposterior and sagittal rotation setup errors were (0.047±0.212)mm, (0.023±0.152)mm and 0.091°±0.090°, significantly less compared with (0.246±0.474)mm, (0.140±0.350)mm and 0.181°±0.210° in group A ( P=0.004, P=0.020, P=0.001), respectively. Optical surface monitoring data were consistent with the obtained results. Conclusions:Thermoplastic head and shoulder molds (with or without vacuum pad) combined with online image registration and six-dimensional robotic couch correction can be applied in HFSRT for brain metastases from NSCLC. The intrafraction setup errors in group B are smaller than those in group A. Optical surface system has certain value in monitoring the intrafractional movement.
RESUMEN
Objective:To compare the positioning errors of individual head-rest combined with thermoplastic fixation mask versus thermoplastic fixation mask alone in patients with head and neck tumors. Methods:Twenty-eight patients who received irradiation with helical tomotherapy in Cancer Hospital of the University of Chinese Academy of Sciences (Zhejiang Cancer Hospital) between October 2019 and April 2020 were included in this study. They were randomly assigned to receive position fixation with either individual head-rest combined with thermoplastic fixation mask (N1 group, n = 14) or thermoplastic fixation mask alone (N2 group, n = 14). Megavoltage computed tomography (MVCT) scanning registration was used to obtain the positioning errors in translation and rotation (ROLL) in the left-right (X), head-food (Y), and belly-back (Z) directions. There were a total of 841 CT scans, consisting of 425 scans in group N1 and 416 scans in group N2. Results:The positioning errors in X, Y, Z and ROLL directions in the N1 group were (1.37 ± 1.04) mm, (1.38 ± 1.12) mm, (1.47 ± 1.62) mm and (1.47 ± 1.62) ° respectively, and they were (1.57 ± 1.21) mm, (2.10 ± 1.51) mm, (1.61 ± 1.50) mm and (1.40 ± 1.30) ° respectively in the N2 group. There was significant difference in positioning errors in the Y direction between N1 and N2 groups ( P = 0.013). In the N1 group, the outward expansion boundaries in X, Y and Z directions was 4.15 mm, 4.23 mm and 4.81 mm respectively, and it was 4.77, 6.31 and 5.08 mm, respectively in the N2 group. In the X direction, there was significant difference in positioning errors taking 3 mm as the dividing point between N1 and N2 groups ( χ2 = 10.516, P < 0.001). In the Y direction, there was significant difference in positioning errors taking 1, 2 and 3 mm as the dividing points between N1 and N2 groups ( χ2 = 24.889, P < 0.001; χ2 = 42.202, P < 0.001; χ2 = 46.204, P < 0.001). In the Z direction, there was significant difference in positioning errors taking 2 mm as the dividing point between N1 and N2 groups ( χ2 = 7.335, P = 0.007). In the N1 group, the percentage of positioning errors < 3 mm in the X, Y and Z directions was 92%, 90% and 92%, respectively. Conclusion:Compared with thermoplastic fixation mask alone, individual head-rest combined with thermoplastic fixation mask can better effectively improve the positioning stability and reduce positioning errors in patients receiving irradiation with helical tomotherapy for head and neck tumors. The combined method is of certain innovation.
RESUMEN
A novel paper-based analytical device(PAD)was prepared and applied to determine the xanthine oxi-dase(XOD)inhibitory activity of Salvia miltiorrhiza extracts(SME).First,polycaprolactone was 3D printed on filter paper and heated to form hydrophobic barriers.Then the modified paper was cut according to the specific design.Necessary reagents including XOD for the colorimetric assay were immobilized on two separate pieces of paper.By simply adding phosphate buffer,the reaction was performed on the double-layer PAD.Quantitative results were obtained by analyzing the color intensity with the specialized device system(consisting of a smartphone,a detection box and sandwich plates).The 3D-printed detection box was small,with a size of 9.0 cm x 7.0 cm x 11.5 cm.Color component G performed well in terms of linearity and detection limits and thus was identified as the index.The reaction con-ditions were optimized using a definitive screening design.Moreover,a 10%glycerol solution was found to be a suitable stabilizer.When the stabilizer was added,the activity of XOD could be maintained for at least 15 days under 4℃or-20℃storage conditions.The inhibitory activity of SME was investigated and compared to that of allopurinol.The results obtained with the PAD showed agreement with those ob-tained with the microplate method.In conclusion,the proposed PAD method is simple,accurate and has a potential for point-of-care testing.It also holds promise for use in rapid quality testing of medicinal herbs,intermediate products,and preparations of traditional Chinese medicines.

Background: Menarche is the most dramatic manifestation of puberty in girls; unlike the biometric developmental changes that occur at puberty, menarche requires the personal adjustment and response of an affected girl in order to attain good menstrual hygiene. This study was designed to evaluate how boarding secondary school girls manage their menstruation in school, away from the guidance of their parents.Methods: A cross sectional survey was performed in four public boarding secondary schools in the study area with the aid of structured questionnaires to evaluate how such girls manage their menstruation while in school.Results: The study population was 975 girls whose survey revealed the mean age at menarche of 12.5±1.4 years. Seven hundred and two (72.0%) respondents had received sexuality education before onset of menarche. Respondents who attained good menstrual hygiene were 775(79.5%). Such respondents were those who had received sexuality education (p<0.001) and those who had access to synthetic sanitary pad (p=0.005). Duration of the menstrual period and the volume of menstrual blood loss did not affect (p=0.219) the ability of respondents to attain good menstrual hygiene. Respondents who received sexuality education had about 605 chances of attaining good menstrual hygiene than those who did not receive such education.Conclusions: A vast majority of the respondents had received sexuality education before onset of menarche and a larger proportion attained good menstrual hygiene. Major factors that positively influenced the girls’ capacity to attained good menstrual hygiene were prior sexuality education and access to synthetic sanitary pad.
RESUMEN
Oro-antral communication is a complication associated with extraction of maxillary posterior teeth, surgeries of the maxillary sinus or pathologies associated with the sinus or the posterior maxilla. Such abnormal communications need to be repaired at the earliest, to maintain oral and nasal complex harmony and to prevent undue complications thereafter. These communications can be repaired by various methods, one of those being buccal fat pad pedicled graft technique which will be clinically evaluated and critically discussed in this paper. The pre-operative, immediate and post-operative measures followed, the eligibility criteria chosen, and the duration of follow up period, will formulate the outline for the study. A careful assessment of the criteria, clinical signs and healing is noted, to establish the outcome of the technique.METHODSAn observational study was undertaken to evaluate the effectiveness of a surgical technique to repair oro-antral communications wherein the pedicled buccal fat pad is used as a graft material. 20 patients with OAC, who were presented to the department of Oral & Maxillofacial Surgery, VS Dental College & Hospital, Bangalore, were recruited for the study. The clinical study was conducted in accordance with the protocol and the results were evaluated on the basis of patient’s comfort towards the procedure, ease of technique, healing time, post-operative complications and recurrence rate of the communication. Details of the technique and a review of the previous studies published were discussed in detail, to form a relevant summary.RESULTSThe clinical study utilised buccal pad of fat as a pedicled graft for the closure of oro-antral communication and the study was compared with previous studies published regarding the same. The technique was found to be more effective and convenient than the other methods to both the patient and operator, owing to its ease of performing, minimal risk of complications from the grafted site and the harvest site, and predictable healing.CONCLUSIONSThe technique is easiest among the various methods recommended so far, pertaining to the procedure and predictability. Although, the training and experience of a skilled operator is equally important in achieving the best results.
