Introduction: This study sought to characterize delays and estimate resulting costs during nephrolithiasis surgery. Methods: Independent observers documented delays during ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) procedures. Fifty index cases over a period of three months was considered sufficient to observe the generalizable trends. Operating room staff, excluding the surgeons, were blinded. Time-related metrics and delays preventing case progression were recorded using a smartphone-accessible data collection instrument. Delays were categorized as: 1) missing equipment; 2) missing personnel; 3) equipment malfunction; or 4) delay due to case complexity. The first two categories were regarded as preventable and the latter two non-preventable. Results: Forty URS and 18 PCNL cases were included. There was a total of 56 delays in 35 (65%) cases. Twelve (67%) PCNLs and 23 (58%) URSs had delays (p=0.57). The mean cumulative delay per case was 3.5±3.2 minutes. Pre-start delays (n=17) were 4.5±3.5 minutes on average while intraoperative delays (n=39) were 3.1±2.9 minutes (p=0.167). Delays were evenly spread among the four categories. Thirty-one (55%) delays were preventable (mean 3.7±3.2 minutes) while 25 (45%) were non-preventable (mean 3.2±3.2 minutes) (p=0.58). This translates to $137 per case in preventable costs. Conclusions: Preventable operative delays are encountered frequently in nephrolithiasis surgery, translating to significant additional charges and costs. We demonstrate a rationale for the development of improved communication and workflow protocols to increase efficiency in endourological surgeries. Key limitations are the observational nature of the study and sample size.

Errors during research can occur not only at the stage of planning, data collection and statistical analysis, but also at the stage of filling in spreadsheets. In most cases they can be easily corrected, otherwise results may be distorted. These errors can be categorized into invalid format and input errors. In the first case, the mixing of the absence of data and the zero values is especially dangerous, since it can lead to systematic errors: overestimation (if the zero values are filled in as the absence of data) or underestimation (if the absence of data is filled in as zero values) of the mean or the prevalence. Input errors are most often random, and their effect decreases with increasing sample size, but for the better analysis they should also be corrected as much as possible. The article provides an algorithm that allows you to find input errors and correct them before statistical analysis.

Background The organizational climate in the operating room is special due to the specific conditions of the patient, and the ethical climate may affect moral distress of the operating room staff. Objective This study determined the relationship between ethical climate and moral distress from staff working in operating rooms of hospitals affiliated to Mashhad University of Medical Sciences. Method This analytical study was performed on 169 operating room staff in Mashhad, Iran. The operating room staff was selected using stratified random sampling. The data were collected via Olson's Hospital Ethical Climate Survey and the Corley Moral Distress Scale and analyzed with IBM Statistical Package for the Social Sciences (SPSS) software version 21. Results The results showed no relationship between the ethical climate, the frequency, and intensity of moral distress of the operating room staff ( p > 0.05). In addition, the mean score of the ethical climate was 3.32 ± 0.48, indicating the average ethical climate in the operating room. The mean frequency and intensity of moral distress were 36.36 ± 11.68 and 48.8 ± 15.92, showing a moderate rate. There was a significant inverse relationship between the dimensions of ethical climate, the relationship with physicians, and the intensity of moral distress ( p <0.05). A significant relationship was found between the intensity of moral distress, the level of education, and field of study ( p <0.05). Conclusion The results of the current study showed that interventional programs should be implemented to reduce moral distress and improve the ethical climate in the operating room.

Objectives To determine the prevalence of nail-biting among children in Karachi and its association with behavioral disorders.                           Methodology Sample size was parents of 171 children between the ages 4-10 selected by convenience sampling. Data collection was conducted with a use of questionnaire in two hospitals of Karachi. All participants of the study were explained the purpose of the study and written consent was obtained. Results The overall prevalence of nail-biting in the sample was 39.2%. The prevalence in boys and girls was not statistically significant (P = 0.06). The mean total SDQ score was 15.3 (SD = 5.3) and the mean prosocial score was 6.8 (SD = 2.2). The comparison of the effect of a child’s schooling neither showed any significant effect on nail-biting frequency (P = 0.093) nor on SDQ score (P = 0.845). Conclusion To conclude more research should be done on the importance of nail biting in children, parents and pediatricians alike should pay special attention to children that bite their nails.

Abstract The efficiency of a Markov chain Monte Carlo algorithm for estimating the mean of a function of interest might be measured by the cost of generating one independent sample, or equivalently, the total cost divided by the effective sample size, defined in terms of the integrated autocorrelation time. To ensure the reliability of such an estimate, it is suggested that there be an adequate sampling of state space— to the extent that this can be determined from the available samples. A sufficient condition for adequate sampling is derived in terms of the supremum of all possible integrated autocorrelation times, which leads to a more stringent condition for adequate sampling than that simply obtained from integrated autocorrelation times for functions of interest. A method for estimating the supremum of all integrated autocorrelation times, based on approximation in a finite-dimensional subspace, is derived and evaluated empirically.

Floriculture is an age-old farming activity in India having immense potential for generating selfemployment and income to farmers. However, the cost of cultivation of flower is high as compared to cereal crop. Level of mechanization for different field operations is one but foremost reason for the higher cost of cultivation. As most of the Indian farmers are marginal and small, a need for manually operated gladiolus planter was felt. The geometric properties of gladiolus corm were determined for designing the seed metering system and seed hopper of the planter. The planter was evaluated in the field when pulled by two persons as a power source and guided by a person. The coefficient of variation and highest deviation from the mean spacing was observed as 12.93% and 2.65cm respectively. The maximum coefficient of uniformity of 90.59% was observed for a nominal corm spacing of 15cm at 0.56 kmh-1 forward speed. An average MISS percentage was observed as 2.65 and 2.25 for nominal corm spacing of 15 and 20 cm. The multiple index was zero for two levels corm spacing and forward speed of operation. The QFI was found in the range of 97.2 and 97.9 percent. The average field capacity of the planter was observed as 0.02 hah-1.The average draft requirement of the planter was found as 821 ± 50.3 N.
