Abstract:
Energy efficiency is a major concern for mesh nodes with limited power supply. So STDMA(spatial time division multiple access) is applied to reduce node’s power consumption in mesh networks. However, the energy cost was still high for solar panel applying with STDMA, due to the fixed slots and numerous start times of nodes. A VF-STDMA(variable frame in STDMA) is proposed based on STDMA protocol. The VF-STDMA dynamically changes the frame size and assigns timeslots to each link according to the network data flows. The start times are reduced by recombining slots. Finally, the optimum routing is obtained through a cross-layer mechanism covering physical layer, MAC layer and network layer. The results show that the algorithms improve energy efficiency as well as decrease energy consumption of solar panel.

Abstract:
Abstract Traffic safety applications using vehicle-to-vehicle (V2V) communication is an emerging technology and promising area within the ITS environment. Many of these applications require real-time communication with high reliability; to meet a real-time deadline, timely and predictable access to the channel. The medium access method used in 802.11p, CSMA with collision avoidance, does not guarantee channel access before a finite deadline. The well-known property of CSMA is undesirable for critical communications scenarios. The simulation results reveal that a specific vehicle is forced to drop over 80% of its packets because no channel access was possible before the next message was generated. To overcome this problem, we propose to use STDMA for realtime data traffic between vehicles. The real-time properties of STDMA are investigated by means of the highway road simulation scenario, with promising results.

Abstract:
Recently, Ad Hoc network is adapted widely in military, agriculture, and disaster rescue owing to the character flexible and fast deployment without infrastructure itself. However, the omnidirectional Ad Hoc cannot fulfill the requirements from people of increasing the capacity and the bandwidth of network caused by drastic explosion of information. By contrast, the directional antenna is more advantage than the omnidirectional one, which have the capability to improve the performance of Ad Hoc including more transmission range, less interference, spatial reuse, more capacity and tactical silence. Based on the existing lecture, a novel directional MAC found on STDMA(Spatial Time Division Multiple Access)is raised and provide high throughput, high transmission rate and low delay to network system which contribute to share massive information and improve the performance of the network.

Abstract:
The angiosperm flower is a complex integrated phenotype, but within this structure there are partly independent units or modules. The interconnections among floral organ traits are hypothesized to be mostly generated by pollinatormediated selection. In this study, we explore whether floral dry mass per area (DMA) in an insect-pollinated herb, Iris pumila, exhibits a modular correlation pattern as has been reported for some size-related traits. We found that the overall pattern of floral organ integration with regard to DMA was uneven in the offspring of Iris pumila derived from a sunexposed and a shaded natural population. Since principal component analysis (PCA) showed that most of the eigenvalue variance was explained by the first two principal components (PCs), these PCs were considered as two floral modules. The greatest factor loadings on the first PC axis was that of the perianth and style arm DMA (PSDMA) and perianth tube DMA (PTDMA),while on the second PC axis, the greatest factor loading was that of stamen DMA (STDMA). The results indicate that the function of the first module would be to attract a pollinating vector, while the second one would reflect male functions. Selection analyses revealed that the targets of phenotypic selection were both intra-floral integration and individual floral traits. Both PSDMA and PC1DMA were under strong linear selection, while PTDMA experienced direct stabilization selection. The level of integration in floral organ DMA expressed in the term of relative eigenvalue variance appeared to be rather low, as was documented for other angiosperm taxa.

Abstract:
The aim of this systematic review is to evaluate and compare the efficacy and safety of temporary tube stoma and conventional loop stoma for the protection of a low anastomosis in colorectal cancer. A systematic literature search was performed using PubMed, EMBASE, Science Citation Index, and Cochrane Central Register of Controlled Trails. Primary outcome measures were anastomotic leakage rate, the reoperation rate for anastomotic leakage, and stoma-related complications. Secondary outcome measures were operation time, length of hospital stay, time to stoma closure, and permanent stoma rate. Four studies were carried out and 642 patients (332 with temporary tube stoma and 310 with conventional loop stoma) met the inclusion criteria. The incidences of anastomotic leakage and reoperation rate were statistically similar in tube stoma and loop stoma groups. In comparison with conventional loop stoma, temporary tube stoma was associated with a significantly less stoma-related complications (odds ratio = 0.20; 95% confidence interval [CI]: 0.08–0.50), and shorter operation and hospital stay time (weighted mean difference = -47.28 minutes, 95% CI: -74.68 to -19.88; and weighted mean difference = -5.22 days, 95% CI: -10.32 to -0.13, respectively). Time to stoma closure was significantly shorter in the temporary tube stoma groups (weighted mean difference = -114.58 days, 95% CI: -148.38 to -80.77). Patients receiving temporary tube stoma had lower rates of stoma-related complications, shorter operation and hospital stay time, and stoma closure time. Tube can be easily removed without second surgery in most cases. Therefore, temporary tube stoma is a feasible and effective alternative to conventional loop stoma for the protection of a low colorectal anastomosis.

Abstract:
Background: Temporary stoma formation for fecal diversion is commonly performed in surgery. The rate of stoma-related complications is high, and the risk increases in patients with prolonged time to closure. Thus, identifying factors that influence the time to stoma closure and the rate of its complications would aid in implementing preventive measures. We aimed to determine predictors affecting the time to stoma closure and to identify risk factors for developing complications following stoma reversal.Methods: A retrospective review including all adult patients who underwent stoma closure from 2012-2018 at our institution was conducted. Multivariate regression analysis was used to determine risk factors affecting time to stoma closure and developing complications after reversal surgery.Results: A total of 63 patients were included. Of those, 50.8% were diagnosed with malignancy. The median time to stoma closure was 222.5 days (interquartile range i.e. IQR 12-2228).Having an American society of anesthesiologists (ASA) class IV was the only significant predictor of prolonged time to closure. For cancer patients, developing complications following stoma formation surgery, and receiving adjuvant therapy significantly increased the time to stoma reversal. In contrast, cancer patients who underwent multi-organ resection had shorter time to closure. The rate of complications following stoma reversal was 30.2%. Having a colostomy and requiring readmission after stoma formation surgery increased the risk of developing complications related to stoma reversal.Conclusions: Multiple factors can impact the time to stoma closure and increase the risk of developing complication related to stoma closure. Awareness about these factors and development of preventive strategies is recommended.

Abstract:
The most common occurred long-term stoma complication is parastomal hernia (PH). The incidence of this complication reaches 50% and, according to Goligher1, the parastomal hernia is an inevitable consequence in a certain percentage of all cases of stoma formation. The factors that may affect the incidence of parastomal hernia include the site of stoma, particularly its position relative to the rectus muscle of abdomen, preoperative mapping out of the stoma site, stoma diameter, intraperitoneal or extraperitoneal bringing out of the intestine and its fixation to fascia, closing of the area around the stoma opening, the mode of operation - planned or emergency, and finally the kind of stoma - ileostomy, colostomy, end stoma and loop stoma. None of these factors, however, has been identified to have the key importance in parastomal hernia formation. It seems that the only factor that significantly increases the incidence of parastomal hernia is the length of post-operative period.

Abstract:
Aim: To determine the effect of pre-operative stoma-site marking (siting) on ostomates' peristomal skin health and quality of life (QoL). Methods: The Uses and Attitudes in Ostomy (U&A Ostomy) study was conducted across 148 stoma units in Spain. Specialist stoma care nurses personally assessed each ostomate and collected demographic and clinical data. This included whether the stoma was sited before surgery, the stoma's characteristics, the type of appliance used, any stoma-related complications and frequency of leakage. Participants were also assessed using the Discolouration, Erosion, Tissue overgrowth (DET) Ostomy Skin Tool (0–15), Global Wellbeing scale (0–10) and Stoma-QoL scale (0–100). Findings: The study included 871 ostomates. Of these, 64% were male and 36% were female, the mean age was 64±13 years and the mean BMI was 26.5±11; 57.5% had a colostomy, 28.6% had an ileostomy and 13.9% had a urostomy. A stoma site had been pre-operatively marked and respected in 53.1%, marked but not respected in 2.1% and not marked in 44.8% of the cases. The proportion of new ostomates whose stoma had been sited was seen to have increased in recent years. Stoma siting was associated with a permanent ostomy (p=.0001), absence of effluent leakage (p=.008), absence of complications (p<.0001), lower DET score (p.0007), higher Stoma-QoL score (p=.018) and higher global wellbeing score (p=.0018). Multivariate analysis revealed that pre-operative stoma siting (p<.0001) and type of ostomy (p<.0001) were independent predictors of optimal peristomal skin (DET score 0). The Stoma-QoL score was higher in ostomates with pre-operative stoma siting (58.3±10.2 vs 57±10.3; p=.018). Global wellbeing was also higher in those with pre-operative stoma siting (7.6±1.8 vs 7.19±1.9; p=.0018). Conclusions: In Spain, pre-operative stoma siting is not yet consistently applied in practice, despite the educative efforts made by health professionals. Stoma siting is a first-line opportunity to reduce the occurrence of peristomal skin complications (PSCs), and thus it is associated with fewer PSCs and greater self-perceived QoL. More effort is needed to extend this practice to the majority of patients undergoing stoma-forming surgery.

An improper stoma creation can cause many complications, varying from minor to life-threatening ones. Conversely, a good functioning stoma, at the ideal site improves patient’s quality of life. Most of the stoma complications occur in the early postoperative period and all clinicians must be familiar to these complications. All measures before and during operation must be taken to avoid these complications. Careful follow up after post operative period can help early diagnosis, proper treatment quick recovery of the patient. This review focus on common complications and treatment options of stoma creation.

Abstract:
AbstractWhen created properly, an ileostomy or colostomy can dramatically improve a patient's quality of life. Conversely, when a patient develops complications related to their stoma, the impact on physical and mental health can be profound. Unfortunately, significant morbidity is associated with stoma creation conveying high rates of both early and late-term complications. Early complications include stomal ischemia/necrosis, retraction, mucocutaneous separation, and parastomal abscess. Late complications include parastomal hernia, prolapse, retraction, and varices. This review will discuss commonly occurring nondermatological stoma complications and detail management strategies for the ostomate and the surgeon.

Abstract:
Background: There are more than 1 million patients with a permanent colostomy and the number is increasing by the rate of 100 000 per year. Clients with a new stoma must master multiple psychomotor skills to remove their pouch, clean the stoma and peristomal skin and empty and dispose of effluent from the pouch. Stoma care self-efficacy has been positively related to ostomy adjustment.Objective: To assess knowledge and practice of stoma care among ostomates.Method: This is a simple descriptive cross sectional study. A total of 94 ostomates who met eligible criteria were purposively sampled. Stoma self care efficacy scale and semi-structured questionnaire was used and face to face interview was done. Data were analyzed using SPSS version 16 program. T test was used to see the mean difference.Result: The knowledge of ostomates on normal stoma and complication of stoma was adequate (61.7%). Majority (92.6%) respondents had good daily care practice like emptying pouch, hand washing before and after procedure and cleaning stoma. Majority of the ostomates suffered from physical problem (89.4%). Of which maximum 72.3% had peristomal skin irritation, then came leakage and odour. More than half (64.9%) of ostomates had higher efficacy.Conclusion: On the basis of findings, it is concluded that there was significant difference in mean knowledge of ostomates with variables pre-operative teaching, training on stoma care, living with stoma for more than 12 months. There was significant difference in mean self care efficacy with variables duration of living with stoma and training on stoma care. Thus training on stoma care should be provided frequently to further improve self care efficacy.Journal of Nobel College of Medicine Vol.4(1) 2015: 36-45

Abstract:
Abstract Background Diverting stoma is often performed in rectal cancer surgery for reducing the consequences of possible anastomotic failure. Closing of stoma follows in most cases after a few months. The aim of our study was to evaluate morbidity and mortality after diverting stoma closure and to identify risk factors for complications of this procedure. Patients and methods At our department, we have performed a retrospective cohort analysis of data for 260 patients with diverting stoma closure from 2003 to 2015. Age, stoma type, patient’s preoperative ASA score, surgical technique and time to stoma closure were investigated as factors which could influence the complication rate. Results 218 patients were eligible for investigation. Postoperative complications developed in 54 patients (24.8%). Most common complications were postoperative ileus (10%) and wound infection (5%). Four patients died (1.8%). There was no effect on complication rate regarding type of stoma, closing technique, patient’s ASA status and patient age. The only factor influencing the complication rate was the time to stoma closure. We found that patients which had the stoma closed prior to 8 months after primary surgery had lower overall complication rate (p<0. 05). Conclusions To reduce overall complication rate, our data suggest a shorter period than 8 months after primary surgery before closure of diverting stoma. As diverting stoma closure is not a simple operation, all strategies should be taken to reduce significant morbidity and mortality rate.

Abstract:
Background and Aims: Stoma-related complications and problems in stoma care are common after gastrointestinal surgery requiring the construction of a stoma. The frequency and types of such complications and problems were evaluated in a patient cohort operated on in Oulu University Hospital. Material and Methods: A detailed questionnaire concerning clinical problems and stoma care was mailed to 163 stoma patients operated on during the years from 1995 to 2001 in Oulu University Hospital. One hundred and nineteen patients (70 percent) answered the questions adequately. The clinical variables concerning stoma complications and the patients' symptoms, problems with stoma care and adaptation to the situation were recorded. Special attention was paid to the patients' general wellbeing and social problems. Results: Thirty-five patients (30%) had stoma complications, most commonly parastomal hernias (18 cases). Patients with an ileostomy had more difficulties with stoma handling more often than the patients with a colostomy. Seventy-eight patients (66%) were well adapted to their stoma, including 49 (72%) of the patients with a colostomy and 25 (56%) of the patients with an ileostomy. Of the 41 non-adapted patients, 12 did not accept their altered body image, ten had problems in social life and nine had difficulties because of faecal leakage. The quality of life analysis of 114 patients showed that their physical condition was better than before the operation in 55 cases (48%), unchanged in 16 (14%) and worse in 43 (38%). General mental health was better than before the operation in 52 cases (46%), unchanged in 23 (20%) and worse in 39 (34%) patients. Social functioning had improved after stoma surgery in 38 cases (34%), remained unchanged in 27 (24%) and deteriorated in 46 (42%) patients after stoma surgery. Patients with a colostomy reported worse subjective physical condition, mental health and social functioning than the patients with an ileostomy. Conclusions: Two-thirds of the patients had adapted to their stoma. The patients with an ileostomy had difficulties in stoma handling and the patients with a colostomy reported their physical, mental and social wellbeing to be affected.

Abstract:
Introduction Stoma formation following colorectal resection is often anticipated prior to surgery. Becoming independent with stoma handling can sometimes delay discharge beyond achievement of discharge criteria. The aim of this study was to assess the impact of preoperative stoma training on length of stay. Methods Patients undergoing colorectal resection within an enhanced recovery after surgery (ERAS) programme were prospectively entered into a database. Retrospective analysis was performed of those who received a stoma as part of their operation. Patients who underwent preoperative stoma training were compared with those who had conventional postoperative training. The primary outcome measure was length of hospital stay. Secondary outcome measures included overall morbidity, stoma related morbidity, ERAS milestone achievement and readmission rates. Results The median length of stay was improved in the patients receiving preoperative stoma training (8 days [interquartile range: 6–10] vs 9 days [interquartile range: 7–19.5], p=0.025). No statistically significant difference was observed in overall morbidity rates, stoma specific morbidity, ERAS milestones or readmission rates. Conclusions Preoperative stoma training can reduce length of stay and could be employed routinely for patients who are planned to have colorectal surgery. Such training can be incorporated within ERAS pathways.

Abstract:
Background: Transverse colostomy is commonly performed to create temporary stoma in rectal cancer patients after neoadjuvant chemoradiotherapy. Conventional methods are either difficult to implement or to care for. To resolve these problems, we herein describe a modified transverse colostomy method. Material and Methods: Two sutures of peritoneum were made as “bridges” to support the stoma. Absorbable sutures were utilized to reinforce the stoma. Once the stoma was created, the stoma bag was immediately placed on the skin. 120 patients who received conventional or modified transverse colostomy between 2008 and 2014 were selected. Then, the two groups of patients were compared for stoma-related complications. Results: The operation time of stoma construction was 34±10 minutes for the conventional method and 28±7 minutes for the modified method (P= 0.009). There were no significant differences between the two groups with respect to postoperative bleeding, bowel obstruction or stoma retraction. Patients with conventional transverse colostomy were remarkably more likely to experience parastoma hernia (P= 0.048) and stoma prolapse (P= 0.038). Conclusion: In comparison with conventional methods, the modified transverse colostomy is a safe and effective diverting technique. It can be readily performed by all kinds of surgeons, especially those in underdeveloped areas. The technique represents a preferred method for constructing temporary stoma in rectal cancer patients treated with neoadjuvant chemoradiotherapy.

Abstract:
AbstractCreating an intestinal stoma is commonly the final aspect of an often emergent and complicated operation under difficult circumstances. While creation of a protruding, tension-free, and well-vascularized stoma is often straightforward, one must be prepared for challenging situations such as a thick abdominal wall and short, thickened mesentery. A successful stoma starts with attentive preoperative planning including site marking, thoughtful consideration of alternatives, and attention to technical detail. The tips provided in this article should facilitate the process of selecting the appropriate intestinal segment, identifying the correct stoma site, and creating a functional stoma even in the most challenging situations. Constructing a high-quality stoma will decrease complications and improve the patient's quality of life. Stoma creation is frequently the only component of an operation that the patient will have to live with for the remainder of his/her life.

Abstract:
<p>Ekstraksi fitur adalah proses pengambilan ciri sebuah objek yang dapat menggambarkan karakteristik dari objek tersebut. Pada penelitian ini, dua buah metode ekstraksi fitur digunakan, yaitu Principal Component Analysis (PCA) dan histogram untuk melakukan deteksi stoma pada gambar penampang daun Freycinetia. Penelitian ini menggunakan frame berjalan yang melakukan pengolahan bagian citra dan melakukan deteksi kemunculan stoma pada bagian citra tersebut. Untuk memodelkan kemunculan stoma, dibuat tiga kelas frame, yaitu frame dengan kemunculan stoma penuh, frame dengan kemunculan sebagian stoma, dan frame tanpa kemunculan stoma. Untuk proses klasifikasi, digunakan pemodelan menggunakan Jaringan Saraf Tiruan (JST) Backprogragation. Hasil percobaan menunjukkan bahwa ekstraksi fitur menggunakan PCA menghasilkan akurasi yang lebih baik dibandingkan dengan metode histogram. Nilai F1-measure yang terbaik yang didapatkan menggunakan ekstraksi fitur PCA ialah 0.9091.</p><p>Kata kunci: deteksi stoma, ekstraksi fitur, Freycinetia, histogram, PCA</p>

Abstract:
Background: The present study is designed to study the indications of intestinal stoma formation, type of stoma formation, complications of intestinal stoma made in patients under emergency or elective setting and postoperative care of the intestinal stomas.Methods: The study was carried out in Department of surgery at J. L. N. Medical College, Ajmer from January 2016 to September 2017. In this study only >12 years age patient were included. The data were collected prospectively and analysed.Results: It was observed that most patients were operated in emergency (90%) as compare to elective (10%) setting for the formation of intestinal stomas. The stoma was formed more in male (58%) as compared to female (42%). There were two peak age group 31-45 year and 45-60 years in which more stoma formation occur. The common indications for stoma were found to be ileal perforation with gangrenous ileum. The common stoma formed was ileostomy (64%) in compared to colostomy (34%). The loop stomas were formed in compared to end stoma and temporary stoma (84%) more formed compared to permanent stoma (16%). The most common complications were found to be skin excoriation (64%) as compared to other complications.Conclusions: Despite increasing surgical expertise, complications of intestinal stomas still occur frequently in all setups and result in high morbidity. Meticulous skin care with regular follow-up, early detection of complications with their timely management along with education and counselling can decrease morbidity.
