Evaluating the effects of using plastic, silicone, and glass on time of sous vide cooking of gravy

Background: Sous vide cooking is popular method of cooking involving a water bath with immersion circulator or a steam convection oven. This process is also known as low-temperature long-time method (LTLT), where food is held at a lower temperature over extended time for cooking (1). Plastic is the more commonly used medium with sous vide cooking. Glass and silicone are an environmentally alternative to plastic, since they are reusable mediums. These alternative mediums have not been studied and may affect the time to reach pasteurization. The purpose of this experiment is to determine how plastic, silicone, and glass influence time in sous vide cooking of gravy to 56.5°C. Methods: Four of each medium: plastic, silicone, and glass containing 500 mL of gravy with SmartButton data loggers at 4°C were introduced into a 56.5 °C water bath for 150 minutes. The data loggers recorded the temperature at one minute intervals. The data was used to run a One-Way Analysis of Variance (ANOVA) to analyze if there were any statistically significant differences between the three mediums and time, and a Scheffe’s test to compare the mean time of each of the mediums. Results: There was a difference in time of sous vide cooking for gravy at 56.5°C between the mediums: plastic, glass, silicone. The p-value was 0.00, therefore rejecting Ho and accepting there is a difference in time of sous vide cooking gravy at 56.5°C between the different mediums: plastic, glass, silicone. Comparing the mediums among each other, it showed that there was a difference between glass and silicone, glass and plastic and no significant difference between plastic and silicone medium. Conclusion: The results indicate that there is a statistically significant difference in time that it took for gravy to reach 56.5°C between the mediums: plastic, silicone, and glass. The mean time for each medium to reach 56.5°C differed; 65 minutes for plastic, 68 minutes for silicone, and 129 minutes for glass. This shows that a more environmentally friendly alternative to plastic sous vide pouches can be used. Silicone pouches show to be the best alternative, least compromising of the come-up and pasteurization time. If sous vide users opt to use glass, the come-up time almost doubles in time.

Background: There is a conflict in the superiority of each of the vasopressin and epinephrine compared to the other. Vasopressin has a vasoconstrictive action that results in an increase of the coronary perfusion pressure. Due to the expensive and sometimes scarce of vasopressin in most hospitals, this study aims to evaluate the response rate of vasopressin compared with epinephrine, in return of ROSC. Methods: In this descriptive-analytical study all patients in the emergency medicine department were enrolled in the study suffered a cardiopulmonary arrest and resuscitation will be done instantly for them (According to the guidelines AHA 2010). Their data were extracted from the hospital records and the success rate of recovery, 3-month survival and complications in patients recovering from the drug used during the CPR were analyzed. Results: A total of 61 patients record were analyzed. 31 patients had received epinephrine alone and 30 patients received a combination of epinephrine and vasopressin. No significant difference was observed between the two groups in terms of sex, sepsis, hypovolemia, renal failure, cancers, drug toxicity, brady, dysrhythmia, PEA, VT, VF, defibrillator, duration of CPR and three month outcome. The mean time of CPR in combination of epinephrine and vasopressin group was 27.26±12.72 and the mean time of CPR in epinephrine group was 27.24±13.510 (p-value= 0.99).Conclusion: Among patients with in-hospital cardiopulmonary arrest in this study no statistically significant difference was obtained between the results of treatment with epinephrine alone and combination of epinephrine and vasopressin.

Abstract BACKGROUND: Neuronavigation is a very beneficial tool in modern neurosurgicalpractice. However, the neuronavigation is not available in most of the hospitals in our country raising the question about its importance in localizing the clavarial extra-axial lesions and to what extent it is safe to operate without it.METHODS: We studied twenty patients with clavarial extra-axial lesions who underwent surgical interventions. All lesions were preoperatively located with both neuronavigation and the usual linear measurements. Both methods were compared regarding the time consumed to localize the tumor and the accuracy of each method to anticipate the actual center of the tumor.RESULTS: The mean error of distance between the planned center of the tumor and the actual was 6.50±1.762 mm in conventional method, whereas the error was 3.85±1.309 mm in IGS method. Much more time was consumed during the Neuronavigation method including booting,registration, positioning. A statistically significant difference was found between the mean time passed in the conventional method and IGS method (2.05±0.826, 24.90±1.334, respectively), P-value<0.001.CONCLUSION: in the setting of limited resources, the linear measurement localization method seems to have an accepted accuracy in localization of clavarial extra-axial lesions and it saves more time than neuronavigation method.

This study aims to investigate whether the use of six selected short stories throughout the duration of a 14-week course could enhance students’ reading comprehension achievement at the end of the semester. Out of the six short stories read, three were chosen as in-class assignments known as ‘Personal Reading Logs’ (hereafter, PRLs). One group of semester two Diploma students taking a reading skills course was selected through a convenience sampling method. A pre-test was conducted by having the students answer a past semester reading quiz of which the results would then be compared to their post-test (final reading exam) results. A paired samples t-test revealed no significant difference in the reading scores of the pre-test and the post-test, t (17) = -.265, p > .05. Since the p-value was bigger than 0.05, this indicated that the mean reading score of the post-test (M = 50.556) was not significantly higher than the mean reading score of the pre-test (M = 49.722). Therefore, the null hypothesis which stated that there was no difference in the mean score of the pre-test and post-test was retained. Overall, the result refuted the findings of other studies promoting the effectiveness of using short stories to enhance L2 reading comprehension achievement.

Abstract Background Chronic rhinosinusitis (CRS) is a common inflammation of the nose and the paranasal sinuses. Intractable CRS cases are generally treated with endoscopic sinus surgery (ESS). Although the effect of ESS on CRS symptoms has been studied, the pattern of symptom improvement after ESS for CRS is yet to be investigated. The aim of this study was to determine the magnitude and sequence of symptom improvement after ESS for CRS, and to assess the possible preoperative factors that predict surgical outcomes in CRS patients. Methods This was a longitudinal prospective study of 68 patients who had CRS (with or without nasal polyps). The patients underwent ESS at King Fahd Hospital of the University, Al Khobar, Saudi Arabia. The Sino-nasal Outcome Test-22 (SNOT-22) questionnaire was used for assessment at four time points during the study: pre-ESS, 1-week post-ESS, 4 weeks post-ESS, and 6 months post-ESS. Results The difference between the mean scores recorded for the five SNOT-22 domains pre-ESS and 6 months post-ESS were as follows: rhinologic symptoms (t-test = 7.22, p-value = < 0.001); extra-nasal rhinologic symptoms (t-test = 4.87, p-value = < 0.001); ear/facial symptoms (t-test = 6.34, p-value = < 0.001); psychological dysfunction (t-test = 1.99, p-value = 0.049); and sleep dysfunction (t-test = 5.58, p-value = < 0.001). There was a significant difference between the mean scores recorded for the five domains pre-ESS and 6 months post-ESS. Rhinologic symptoms had the largest effect size (d = 1.12), whereas psychological dysfunction had the least effect size (d = 0.24). The only statistically significant difference in the SNOT-22 mean scores recorded 4 weeks post-ESS was observed between allergic and non-allergic patients (t = − 2.16, df = 66, p = 0.035). Conclusion Understanding the pattern of symptom improvement following ESS for CRS will facilitate patient counselling and aid the optimization of the current treatment protocols to maximize surgical outcomes and quality of life. Level of evidence Prospective observational.

Introduction: A novel virus, SARS-CoV-2, has caused a fatal global pandemic which particularly affects the elderly and those with comorbidities. Hip fractures affect elderly populations, necessitate hospital admissions and place this group at particular risk from COVID-19 infection. This study investigates the effect of COVID-19 infection on 30-day hip fracture mortality. Method: Data related to 75 adult hip fractures admitted to two units during March and April 2020 were reviewed. The mean age was 83.5 years (range 65–98 years), and most (53, 70.7%) were women. The primary outcome measure was 30-day mortality associated with COVID-19 infection. Results: The COVID-19 infection rate was 26.7% (20 patients), with a significant difference in the 30-day mortality rate in the COVID-19-positive group (10/20, 50%) compared to the COVID-19-negative group (4/55, 7.3%), with mean time to death of 19.8 days (95% confidence interval: 17.0–22.5). The mean time from admission to surgery was 43.1 h and 38.3 h, in COVID-19-positive and COVID-19-negative groups, respectively. All COVID-19-positive patients had shown symptoms of fever and cough, and all 10 cases who died were hypoxic. Seven (35%) cases had radiological lung findings consistent of viral pneumonitis which resulted in mortality (70% of mortality). 30% ( n = 6) contracted the COVID-19 infection in the community, and 70% ( n = 14) developed symptoms after hospital admission. Conclusion: Hip fractures associated with COVID-19 infection have a high 30-day mortality. COVID-19 testing and chest X-ray for patients presenting with hip fractures help in early planning of high-risk surgeries and allow counselling of the patients and family using realistic prognosis.

The aim of this study was to evaluate the effect of implant surface treatment with carboxyethylphosphonic acid and fibroblast growth factor 2 on the bone–implant interface during the osseointegration period in vivo using an animal model. The present research was carried out in six minipigs, in whose left tibia implants were inserted as follows: eight implants with a standard surface treatment, for the control group, and eight implants with a surface treatment of carboxyethylphosphonic acid and immobilization of FGF-2, for the test group. At 4 weeks after the insertion of the implants, the animals were sacrificed for the histomorphometric analysis of the samples. The means of the results for the implant–bone contact variable (BIC) were 46.39 ± 17.49% for the test group and 34.00 ± 9.92% for the control group; the difference was not statistically significant. For the corrected implant–bone contact variable (BICc), the mean value of the test group was 60.48 ± 18.11%, and that for the control group, 43.08 ± 10.77%; the difference was statistically significant (p-value = 0.035). The new bone formation (BV/TV) showed average results of 27.28 ± 3.88% for the test group and 26.63 ± 7.90% for the control group, meaning that the differences were not statistically significant (p-value = 0.839). Regarding the bone density at the interthread level (BAI/TA), the mean value of the test group was 32.27 ± 6.70%, and that of the control group was 32.91 ± 7.76%, with a p-value of 0.863, while for the peri-implant density (BAP/TA), the mean value of the test group was 44.96 ± 7.55%, and that for the control group was 44.80 ± 8.68%, without a significant difference between the groups. The current research only found a significant difference for the bone–implant contact at the cortical level; therefore, it could be considered that FGF-2 acts on the mineralization of bone tissue. The application of carboxyethylphosphonic acid on the surface of implants can be considered a promising alternative as a biomimetic coating for the immobilization of FGF-2. Despite no differences in the new bone formation around the implants or in the interthread or peri-implant bone density being detected, the biofunctionalization of the implant surface with FGF-2 accelerates the mineralization of the bone–implant interface at the cortical level, thereby reducing the osseointegration period.

Objective The purpose of this study was to determine the effect of three-dimensional (3D) binocular, stereoscopic, and two-dimensional (2D) monocular visualization on robotics-assisted mitral valve annuloplasty versus conventional techniques in an ex vivo animal model. In addition, we sought to determine whether these effects were consistent between novices and experts in robotics-assisted cardiac surgery. Methods A cardiac surgery test-bed was constructed to measure forces applied during mitral valve annuloplasty. Sutures were passed through the porcine mitral valve annulus by the participants with different levels of experience in robotics-assisted surgery and tied in place using both robotics-assisted and conventional surgery techniques. Results The mean time for both the experts and the novices using 3D visualization was significantly less than that required using 2D vision (P < 0.001). However, there was no significant difference in the maximum force applied by the novices to the mitral valve during suturing (P = 0.7) and suture tying (P = 0.6) using either 2D or 3D visualization. The mean time required and forces applied by both the experts and the novices were significantly less using the conventional surgical technique than when using the robotic system with either 2D or 3D vision (P < 0.001). Conclusions Despite high-quality binocular images, both the experts and the novices applied significantly more force to the cardiac tissue during 3D robotics-assisted mitral valve annuloplasty than during conventional open mitral valve annuloplasty. This finding suggests that 3D visualization does not fully compensate for the absence of haptic feedback in robotics-assisted cardiac surgery.

Background & Method: We conducted a double blinded study at Index Medical College Hospital & Research Centre, Indore. The sample size was determined to be minimum of 120 cases as based upon previous years admission due to acute bronchiolitis. Initially, 146 cases were included in the study out of which 23 cases dropped out of the study after giving consent by guardian for participation in the study as they left against medical advice from the hospital. Result: The mean difference of CSS between 0 minutes to 60 minutes of nebulisation between groups in all cases was 0.4 ± 0.6, between 60 minutes and 4 hours was 0.8 ± 0.6, between 4 to 8 hours was 0.7 ± 0.6, between 8-12 hours was 0.6 ± 0.4, between 12-24 hours was 1.6 ± 0.9 and between 24-48 hours was 1.9 ± 0.9.The mean values and resultant p-value of ANOVA of various nebulising agents used for improvement in CSS shows significant association between various nebulising agents used along with improvement in CSS at the end of assessment at 48 hours of treatment. Conclusion: This study was conducted to establish the efficacy of each nebulisation agent (i.e. adrenaline, 3% hypertonic saline and normal saline) currently used and compare the outcomes as there is not enough evidence amongst Indian population on level of efficacy of each drug in causing improvement in symptoms and signs in various severities of bronchiolitis in early childhood. Comparison of significant improvement in mean difference in CSS at various intervals in all cases compared between groups by post hoc test revealed non-significant difference (p-value 0.700) between 3% hypertonic saline and normal saline.
