Cyberbullying has been an emerging issue in recent years where research has revealed that users generally spend an increasing amount of time in social networks and forums to keep connected with each other. However, issue arises when cyberbullies are able to reach their victims through these social media platforms. There are different types of cyberbullying and like traditional bullying; it causes victims to feel overly self-conscious, increases their tendency to self-harm and generally affects their mental state negatively. Such situations occur due to security issues such as user anonymity and the lack of content restrictions in some social networks or web forums. In this paper, we highlight the existing solutions, which are Intrusion Prevention System and Intrusion Detection System from a number of researchers. However, even with such solutions, cyberbullying acts still occurs at an alarming rate. As such, we proposed an alternative solution that aims to prevent cyberbullying activities at a younger age, e.g., young children. The application would provide an alternative method to preventing cyberbullying activities among the younger generations in the future.

Purpose: We report the results and experience of a tertiary care center in laparoscopic transperitoneal heminephrectomy for the treatment of a non-functioning upper pole moiety of duplex kidney in adults. Materials and Methods: The key point of the technique included the placement of a 6-Fr ureteric catheter in the healthy ureter at the beginning of the procedure under fluoroscopic guidance cystoscopically. A standard laparoscopic 3- to 4-port placement was done after placing the patient in a 45 to 90 degrees lateral decubitus position. The upper pole was mobilized transperitoneally and transected using a harmonic scalpel. Results: A total of 17 patients aged 19 to 44 years underwent laparoscopic upper pole heminephrectomy. All patients had a complete duplicated renal collecting system on the ipsilateral side. Three patients were found to have ureterocele. The average blood loss was minimal (50–150 mL) with a mean of 95 ml. None of the patients required any blood transfusions. The mean operative time was 220 minutes (range, 160–315 minutes). The average length of hospital stay was 3 days (range, 2–4 days). Only 2 patients had Clavien-Dindo grade 3a complications, which were managed by double J stenting and percutaneous aspiration, respectively. Conclusions: Laparoscopic heminephrectomy is playing a cornerstone role in the treatment of the non-functioning moiety of duplex kidneys. The procedure is safe, efficient and offers the typical preoperative and postoperative benefits of laparoscopic surgery. The rate of complications in adults is acceptable and is similar to that reported in pediatric patients.

Objectives: Health systems are shifting from traditional methods of healthcare delivery to delivery using digital applications. This change was introduced at a primary care centre in Chandigarh, India that served a marginalised population. Afterestablishing the digital health system, we explored stakeholders’ perceptions regarding its implementation. Methods: Ethnographicmethods were used to explore stakeholders’ perceptions regarding the implementation of the Integrated Health InformationSystem for Primary Health Care (IHIS4PHC), which was developed as a patient-centric digital health application. Data were collected using focus group discussions and in-depth interviews. Participatory observations were made of day-todayactivities including outpatient visits, outreach field visits, and methods of health practice. The collected information wasanalysed using thematic coding. Results: Healthcare workers highlighted that working with the digital health system was initiallyarduous, but they later realised its usefulness, as the digital system made it easier to search records and generate reports,rapidly providing evidence to make decisions. Auxiliary nurse midwives reported that recording information on computerssaved time when generating reports; however, systematic and mandatory data entry made recording tedious. Staff were apprehensiveabout the use of computer-based data for monitoring their work performance. Patients appreciated that theirprevious records were now available on the computer for easy retrieval. Conclusions: The usefulness of the digital health applicationwas appreciated by various primary healthcare stakeholders. Barriers persisted due to perceived needs for flexibilityin delivering healthcare services, and apprehensions continued because of increased transparency, accountability, and dependenceon computers and digital technicians.

Improving the Diffusion of the Stream Cipher Salsa20 by Employing a Chaotic Logistic Map

Almazrooie, Mishal,Samsudin, Azman,Singh, Manmeet Mahinderjit Korea Information Processing Society 2015 Journal of information processing systems Vol.11 No.2

The stream cipher Salsa20 and its reduced versions are among the fastest stream ciphers available today. However, Salsa20/7 is broken and Salsa20/12 is not as safe as before. Therefore, Salsa20 must completely perform all of the four rounds of encryption to achieve a good diffusion in order to resist the known attacks. In this paper, a new variant of Salsa20 that uses the chaos theory and that can achieve diffusion faster than the original Salsa20 is presented. The method has been tested and benchmarked with the original Salsa20 with a series of tests. Most of the tests show that the proposed chaotic Salsa of two rounds is faster than the original four rounds of Salsa20/4, but it offers the same diffusion level.

The majority of the children experience milder coronavirus disease 2019 (COVID-19) symptoms. Children represent a significant source of community transmission. Children under 18 years of age account for an estimated 4.8% of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections globally. However, no conclusive statements pertaining to the multi-fold aspects of the virus in children could be drawn due to the lower prevalence of pediatric cases. The present study was conducted to identify the indirect impact of SARS-CoV-2 infections on developing herd immunity among children in the age group 3 to 18 years by investigating their antibody levels. In the study, 240 children aged 3∼18 years were recruited by the Department of Pediatrics, Government Medical College and Hospital, Amritsar, India, and quantification of the antibodies was performed at the Viral Research and Diagnostic Laboratory (VRDL), Government Medical College (GMC), Amritsar, India. Out of the 240 serum samples, 197 (82.08%) showed seropositivity, while 43 (17.92%) were seronegative. When stratified, it was observed that in the age group 3∼6 years, 22.33% of children were found to have anti-SARS-CoV-2 antibodies while in the age groups 7∼10 years, 11∼14 years, and 15∼18 years, respectively, 37.06%, 30.46%, and 10.15% were seropositive. Although there was seroconversion among children which was useful for predicting the next wave, no differences in seropositivity were observed between adults and children.

Purpose: To compare patients with sepsis due to obstructive urolithiasis (Sep-OU) and underwent drainage by percutaneous nephrostomy (PCN) or a double-J (DJ)-ureteral stent and to identify predictive risk factors of DJ stent failure in these patients. Materials and Methods: We reviewed our records from January 2013 to July 2018 and identified 286 adult patients with Sep-OU out of which 36 had bilateral involvement, thus total 322 renal units were studied. Urologic residents in training carried out both ureteral stenting and PCN tube placement. Demographic data and stone characteristics were recorded along with Charlson comorbidity index. For predicting risk factors of DJ stent failure, those variables that had a p-value <0.1 in univariate analysis were combined in a multinomial regression analysis model. Results: The patients with PCN placement were significantly older than those with DJ stent placement (p=0.001) and also had significant number of units with multiple calculi (p=0.018). PCN was also placed more frequently in those patients with a upper ureteric calculi (p<0.05). On multinomial regression analysis multiple calculi (p=0.014; odds ratio [OR], 4.878; 95% confidence interval [CI], 1.377–17.276) and larger calculi size (p=0.040; OR, 0.974; 95% CI, 0.950–0.999) were the significant predictors of DJ stent failure. Conclusions: In patients with sepsis from obstructive urolithiasis due to larger and multiple calculi a PCN placement might be better suited although this data requires further prospective randomized studies to be extrapolated.

Purpose: A prospective study evaluating impact of percutaneous nephrolithotomy (PCNL) on renal function following PCNL using ethylenedicysteine (EC) renal scan. Does multiplicity of access tracts play a role?Materials and Methods: A prospective observational study was done and patients undergoing PCNL for renal calculi at our urology department were selected. Renal Tc99m EC scan was done pre-surgery and at 3 months follow-up. An assessment was done on decline in glomerular filtration rate (GFR) in postoperative period based on number of access tracts required. Results: A total of 110 patients were enrolled in the study. The total number of punctures was 170 with 141 being supra-costal puncture and 29 infra-costal. The total number of single punctures were 60 and classified as Group I whereas patients with double puncture and triple puncture (40 and 10 patients, respectively) were classified as Group II. Mean postoperative split renal function (in Tc99m EC scans) of patients of Group I (40.93±19.62%) was found to be higher than that of Group II (32.82±16.98%). Mean change (decline) in GFR for single, double and triple tracts were 2.68 mL/min, 3.80 mL/min, and 4.2 mL/min, respectively. Conclusions: PCNL used for stone removal can improve renal function by eradicating obstruction; however, this procedure may itself negatively impact the functions of the targeted kidney. Our study showed post PCNL decrease in GFR which worsens with an increasing number of accesses.
