Sports Tourism In Post Conflict Peace Building: Evidence From Swat, Pakistan

Taliban uprising in Swat followed by military operations and floods severely damaged the tourism industry of Swat. Skiing festival in Malamjabba and Aman Festival in Kalam were instrumental in bringing tourists back to Swat in post conflict scenario. The study focused on the contribution of Skiing at MalamJabba in revival of tourism and post conflict peace building. Mixed method approach was used to collect data from fifty respondents that included tourists, tourism service providers and representatives of relevant stake holders from government and private organizations. Questionnairs followed by in depth interviews were used to collect the data. Findings of the study indicated that skiing played a very important role in the revival of tourism. Most of the tourist whose primary motivation was skiing at Malamjabbaalso visited or had intentions to visit other areas of Swat. Local communities are engaged in the industry at different levels constituting about 91 percent of the total labor force. Winter sports and increasing range of tourism products means increasing tourist season in the area that provides sustainable source of livelihoods for local community. Engagement of youth in sports and income generating activities provides an important tool for the peace building in the area

In Silico Modelling to Assess the Electrical and Thermal Disturbance Provoked by a Metal Intracoronary Stent during Epicardial Pulsed Electric Field Ablation

[EN] Background: Pulsed Electric Field (PEF) ablation has been recently proposed to ablate cardiac ganglionic plexi (GP) aimed to treat atrial fibrillation. The effect of metal intracoronary stents in the vicinity of the ablation electrode has not been yet assessed. Methods: A 2D numerical model was developed accounting for the different tissues involved in PEF ablation with an irrigated ablation device. A coronary artery (with and without a metal intracoronary stent) was considered near the ablation source (0.25 and 1 mm separation). The 1000 V/cm threshold was used to estimate the PEF-zone¿. Results: The presence of the coronary artery (with or without stent) distorts the E-field distribution, creating hot spots (higher E-field values) in the front and rear of the artery, and cold spots (lower E-field values) on the sides of the artery. The value of the E-field inside the coronary artery is very low (~200 V/cm), and almost zero with a metal stent. Despite this distortion, thePEF-zone contour is almost identical with and without artery/stent, remaining almost completely confined within the fat layer in any case. The mentioned hot spots of E-field translate into a moderate temperature increase (<48 _C) in the area between the artery and electrode. These thermal side effects are similar for pulse intervals of 10 and 100 _s. Conclusions: The presence of a metal intracoronary stent near the ablation device during PEF ablation simply `amplifies¿ the E-field distortion already caused by the presence of the vessel. This distortion may involve moderate heating (<48 _C) in the tissue between the artery and ablation electrode without associate Background: Pulsed Electric Field (PEF) ablation has been recently proposed to ablate cardiac ganglionic plexi (GP) aimed to treat atrial fibrillation.

A review of biophysiological and biochemical indicators of stress for connected and preventive healthcare

Stress is a known contributor to several life-threatening medical conditions and a risk factor for triggering acute cardiovascular events, as well as a root cause of several social problems. The burden of stress is increasing globally and, with that, is the interest in developing effective stress-monitoring solutions for preventive and connected health, particularly with the help of wearable sensing technologies. The recent development of miniaturized and flexible biosensors has enabled the development of connected wearable solutions to monitor stress and intervene in time to prevent the progression of stress-induced medical conditions. This paper presents a review of the literature on different physiological and chemical indicators of stress, which are commonly used for quantitative assessment of stress, and the associated sensing technologies

Calcium levels and metabolic disturbance in renal disease patients receiving hemodialysis: a cross sectional study highlighting its association in dialysis patients

Background: The aim of this study was to determine the disturbances in Calcium and other mineral levels in patients on hemodialysis at Tabba Kidney Institute, Karachi, Sindh, Pakistan.Methods: A cross sectional observational study through convenient sampling technique was conducted from January 2017 to August 2017 at Tabba Kidney Institute, Karachi after obtaining ethical approval. 255 patients, all above 18 years of age and on hemodialysis were included in the study. Multi-organ failure patients on dialysis, other systemic diseased patients on hemodialysis were excluded. Demographic variables, mineral levels, symptoms and supplementations were recorded. SPSS version 20.0 was used for data analysis.Results: A total of 255 patients on hemodialysis were selected and divided into groups depending upon median years of hemodialysis below and above 5 years of hemodialysis. Median and IQR of calcium were 8.8 and 8.2-9.1 mg/dl for below 5 years, 8.6 and 8.1-9.1 mg/dl for above 5 years (P value=0.44). Median and IQR of phosphate were 4.9 and 3.9-5.7 mg/dl for below 5 years and 4.6 and 3.7-5.5 mg/dl for above 5 years (P value=0.21). Median and IQR of parathyroid hormone were 393 and 212-699 pg/ml for below 5 years and 329 and 128-657 pg/ml for above 5 years. (P value=0.13) Median and IQR of albumin were 4.0 and 3.6-4.2 mg/dl for below 5 years and 4.0 and 3.8-4.3 for above 5 years (P value=0.30). Total of 18 (10.9%) had para thyroidectomy.Conclusions: Present study showed that significant difference in mineral levels did not exist in patients on hemodialysis as regards to the duration of dialysis. However clinical features had a tendency to decrease as duration of dialysis increased to above 5 years. Para thyroidectomy and itching were two main significant findings in this study

Renal bone disease in patients on hemodialysis: an observational study focusing on the variation of calcium metabolism

Background: The aim of this study was to determine the disturbances in the levels of mineral in the body due to hemodialysis at different levels of parathormone levels and to assess its association with the calcium levels.Methods: Study was a cross sectional for the period of 6 months taking ethical approval. Total 255 cases were registered in this study after taking their informed consent. The cases were divided into three groups according to PTH level. Group 1 has 87 subjects with PTH level &lt;250, group 2 has 102 subjects with PTH level 250-650 and group 3 has 66 cases with PTH level &gt;650. The cases were taking hemodialysis for greater than 6 months and have the ages more than 18 years were included in this study. The demographic data includes age, sex dialysis related data like duration of hemodialysis, levels of calcium, phosphorus, albumin, PTH, ALP were observed.Results: Hemodialysis duration were recorded in respective three groups as 7.28±5.71, 6.26±5.56 and 6.15±4.30 days respectively  (P=0.319). Calcium was found in group 1, 8.70±0.81, in group 2, 8.39±0.89 and in group 3, 8.76±0.82 (P=0.01). PTH level in three respective group were recorded to be 123.46±74.15, 418.47±115.49 and 1314.67±1188.63 (P &lt;0.001).Conclusions: Present study showed that significant difference was found in mineral levels in patients on hemodialysis with PTH level as well as with alkaline phosphatase level. Nevertheless, no significant difference was found with duration of dialysis and with parameter of albumin

Management of Fournier’s Gangrene; A Randomized Controlled Trial at High Volume Center Comparing the Efficacy of Honey and Eusol Dressing in Wound Healing

OBJECTIVE: To assess the effectiveness of honey dressing in Fournier’s Gangrene against conventional Edinburgh University solution of lime (EUSOL) dressing. METHODOLOGY: This was a prospective experimental study conducted in Liaquat National Medical College and Hospital Karachi for duration of 5 and half years. Total 44 patients having gangrene and no co morbid conditions were included in this study. Patients who had co-morbid conditions like deranged coagulation profile and CVA, who were not willing to participate or loss to follow up were excluded from the study. After getting baseline blood workup (i.e. CBC, S. Creatinine, S. Electrolytes, Urine D/R, C/S and Diabetic workup) done and taking consent, the patients were immediately shifted to operation theatre, the incision and drainage was performed, and the necrotic tissues were debrided. Pus cultures were sent, and patients were started on routine intravenous antibiotics (3rd generation Cephalosporin and metronidazole). A Dressing of wound was done randomly by honey in Group A and by Eusol in Group B. Patients were discharged after wound was completely healed. The data were obtained and analyzed by using SPSS version 20. Mann-Whitney U-test and chi-square test was applied to find out the significance. RESUTS: The patients in Group A got slough cleared in4.82±0.96 days, on average requiring 3.22±0.75 number of debridement’s, complete wound healing and duration of hospital stay being 9.54±0.74 days. The patients in Group B got slough cleared in 8±0.87 days, requiring 5.32±0.72 number of debridement’s, complete wound healing and duration of hospital stay 13.68±1.09 days.There was a significant difference in slough clearance, number of debridement’s required, time taken for complete wound healing and hospital stay between Group A and Group B (P-value <0.001). CONCLUSION: This study predicted that honey is very valuable in the management of Fournier’s gangrene as it ensured early clearance of slough, required lesser number of debridement’s, had early wound healing and had relatively shorter duration of stay in hospital than those treated with conventional EUSOL as dressing material
