Implementation of a "Same Night" Appendectomy (SNAppy) Discharge Protocol: A Quality Improvement Initiative.

Appendectomy is curative for appendicitis and prolonged hospitalization is unnecessary for un-complicated disease. We implemented a protocol to expedite discharge of patients post-appendectomy. Using multiple plan-do-study-act (PDSA) cycles, the protocol functions in three phases of care. Pre-operatively, expectations for discharge are established, antibiotics and acetaminophen are administered. Intra-operatively, a foley catheter is avoided and the maximum dose of local analgesic, routine skin prophylaxis, ondansetron and ketorolac are administered. Post-operatively, patients with stable vital signs, pain controlled, tolerating liquids and able to mobilize are discharged. The primary outcome measured was length of stay (LOS) post-procedure. Counterbalance measures were unexpected return to the emergency department (ED) and in-patient bed utilization. Impact of PDSA cycles was quantified using statistical process control charts and Mann Whitney U test. All statistical tests were 2-sided and P value≤0.05 deemed to be statistically significant. A total of 332 patients were identified over a 2-year period, 147 pre-protocol implementation, 185 afterwards. The median age was 9 years old (IQR:6-11), procedure duration 40min (IQR 29-53). The median post-op LOS pre-protocol was 11.2h (IQR: 7.1-16.2) compared to 1.5h (IQR: 1.1-4.2) after implementation (P<0.00001). There were 10 returns to the ED pre-protocol (6.8%) and 17 after implementation (9.2%), (p=0.65). Pre-protocol, no patients were discharged directly from the OR compared to 68% after implementation. There was no difference in ED LOS (median 9:03 vs 9:14, p<0.48). Implementation of the SNAppy protocol significantly reduced the post-operative LOS and inpatient bed utilization without increasing ED returns. III.

SELECTING AN ADEQUATE MODEL FOR TIME SERIES DECOMPOSITION WHEN THE TREND CURVE IS QUADRATIC

The Buys-Ballot (B-B) approach for the decomposition of additive and multiplicative models in descriptive time series (TS) was examined in this paper. The selection of an adequate model is very important as it shows the underlying structure of the series because the fitted model will be used for future forecasting. Mis-specifying the model characteristics of the data is consequential and can result in biased tests and false predictions The Buys-Ballot method was demonstrated for the selection of an appropriate model and a statistical test that will aid in the selection between additive and multiplicative models was proposed when the trending curve is quadratic. The model identified was used for the forecast. Using the B-B technique, the column variances for the additive model do not contain the seasonal effect while that of the multiplicative model contains the seasonal effect. This distinction was then applied to select between additive and multiplicative models. The chi-square test was proposed for the selection between additive and multiplicative models for the decomposition of TS data. The results when applied to a quadratic trend curve reveal that the appropriate model for the decomposition of the data is the additive model as all calculated chi-square values are within the chi-square acceptance region based on a two-tail test at a 1% level of significance. The additive model identified was then used to decompose the series and the trend analysis model was used for the forecast of the series. The chi-square test was proposed to justify the Buys-Ballot method for...

Memetic-Based Biogeography Optimization Model for the Optimal Design of Mechanical Systems

The science of biogeography was described through mathematical equations in 1967 by Robert MacArthur and Edward Wilson. In 2008, Dan Simon presented an algorithm called biogeography-based optimization, or BBO, which used some of the principles and definitions described in MacArthur and Wilson’s book. The objectives of this work were to study the behavior of the BBO method when it is hybridized with other evolutionary search methods and to analyze the effect of its application to some examples of mechanical engineering systems. The operators considered in the hybridization study are genetic recombination (crossover) and local search, aiming to overcome the limitations and difficulties that arise when using the original BBO. The results of the original BBO were promising in the context of a global search. However, there is a diversity problem that does not allow for good quality increments in the final phase of the evolutionary process. The additional modifications included, such as the concept of blending in migration, the cycle of mutations and the replacement of the worst solutions by injection of new ones, all show positive effects on the method’s performance. However, the biggest increase happened with the implementation of the hybridization processes. Crossover improved the speed and diversity of the population in some cases, while local search helped the algorithm in later generations, allowing it to quickly reach the optimum point. With this mentioned, it is important to note that the best results were all obtained with the fully modified algorithm. Statistical tests were implemented to validate the significance of changes due to modifications included in the original proposal of BBO.

It is important to emphasize that the data collected for the purpose of this research were obtained in the locality of Jerez, in the state of Zacatecas; therefore, its results can only be generalized to locations with similar social, economic, and demographic conditions.

Unraveling the complexity of children’s thinking about poverty: Upper elementary school children’s perspectives on its causes and solutions

This study examines children’s perspectives on the causes and solutions to poverty in upper elementary school. Participants were 248 fourth-grade children (8 to 11 years old) enrolled in public schools in northern Portugal. Children participated in individual interviews. Following a mixed-methods approach, data analysis involved a qualitative phase (thematic analysis) and a quantitative phase (non-parametric statistical tests). Children mentioned naïve or fatalistic, individualistic, and contextual causes and proposed naïve or unrealistic solutions, remediating actions by the individual, remediating actions by others, self-reliance actions, and a call for social change. Children who mentioned contextual causes stated a higher number of causes overall. Children highlighting individualistic causes suggested more individual remediating solutions, while children stating contextual causes proposed more remediating solutions by others. Both were equally likely to offer self-reliance individual solutions. All children advocating for social change identified contextual causes. Results are discussed, shedding light on the complexity of children’s thinking.

The Effect of Temulawak and Ginger on Changes in Blood Pressure in Pregnant Women and Pain Reduction in Labouring Women in BPM Suryani North Padang Lawas Regency

Hypertension in pregnancy has a significant impact on maternal and fetal health. It can lead to complications such as placental abruption, organ failure, intravenous coagulation, preeclampsia, preeclampsia to become eclampsia, risk of intrauterine development, premature birth and intrauterine death. The treatment of gestational hypertension may be either pharmacological or non-pharmacological in nature. Non-pharmacological therapy for the treatment of hypertension in pregnancy may employ the use of ginger and temulawak. This study was conducted at BPM Suryani. The population comprised all pregnant women at BPM Suryani, numbering 154. The sample consisted of pregnant women with gestational hypertension, numbering 34. The recommended dose of dried temulawak and ginger is 25 grams, boiled in 200 ml of water until 100 ml of boiled water is obtained. The boiling time is 2-5 minutes. The temulawak and ginger are administered once a day for one week. At the outset of the study, the blood pressure of pregnant women with gestational hypertension was ascertained. Following the administration of temulawak and ginger, the respondents were again subjected to monitoring of their blood pressure. The data were analysed using a statistical test, namely the t-test, which is a paired sample t-test. A significant relationship was observed between systolic and diastolic blood pressure values before and after the administration of temulawak and ginger (p-value &lt;0.05). The average difference in systolic blood pressure before and after the intervention was 5.82 mmHg with a p-value on systolic blood pressure of The p-value was 0.000 (p-value &lt;0.05) for systolic blood pressure and 0.026 (p-value &lt;0.05) for diastolic blood pressure. These findings suggest that the content of temulawak and ginger can be used in reducing blood pressure in pregnant women with gestational hypertension.

Selective Neurectomy with Regenerative Peripheral Nerve Interface Surgery for Facial Synkinesis.

Background: Selective neurectomy (SN) typically leaves cut nerve endings to be either free-floating or buried in facial muscles. Regenerative peripheral nerve interfaces (RPNIs) use autologous skeletal muscle grafts to provide a nonfacial muscle target for reinnervation. Objective: To evaluate the effectiveness of RPNI surgery with SN for improving postoperative facial function through botulinum toxin use and facial movement metrics. Methods: This was a retrospective cohort study comparing patients with synkinesis undergoing SN with and without RPNI surgery. Outcomes included assessing botulinum toxin dosage/frequency and facial movement metrics (margin to reflex distance, brow movement, smile excursion). Statistical tests were applied based on variable distribution. Results: Twenty-four patients were included (12 with RPNI surgery and 12 without; average age, 52.3 and 55.0 years, respectively; p = 0.552). No significant differences were observed in etiology or nerves sacrificed. Patients with RPNI surgery required lower botulinum toxin dosage (72.2 vs. 90.3 units; p = 0.031) and had longer treatment intervals (83.5%, 5.6 months vs. 17.9%, 4.6 months; p = 0.015). No significant differences were observed in facial movement metrics. Conclusion: RPNI surgery with SN may improve facial function as measured by a proxy of reduction in postoperative botulinum toxin dosage and frequency.

Microbiome metabolic capacity is buffered against phylotype losses by functional redundancy.

Diet can affect gut microbiome taxonomic composition and diversity, but its impacts on community-level functional capabilities are less clear. Host health and fitness are increasingly being linked to microbiome composition and further modeling of the relationship between microbiome taxonomic and metabolic functional capability is needed to inform these linkages. Invertebrate animal models like the omnivorous American cockroach are ideal for this inquiry because they are amenable to various diets and provide high replicates per treatment at low costs and thus enabling rigorous statistical analyses and hypothesis testing. Microbiome taxonomic composition is diet-labile and diversity was reduced after feeding on unbalanced diets (i.e., post-treatment), but the predicted functional capacities of the post-treatment microbiomes were less affected likely due to the resilience of several abundant taxa surviving the perturbation as well as many metabolic functions being shared by several taxa. These results suggest that both taxonomic and functional profiles should be considered when attempting to infer how perturbations are altering gut microbiome services and possible host outcomes.

Video-based estimation of blood pressure.

In this work, we propose a non-contact video-based approach that estimates an individual's blood pressure. The estimation of blood pressure is critical for monitoring hypertension and cardiovascular diseases such as coronary artery disease or stroke. Estimation of blood pressure is typically achieved using contact-based devices which apply pressure on the arm through a cuff. Such contact-based devices are cost-prohibitive as well as limited in their scalability due to the requirement of specialized equipment. The ubiquity of mobile phones and video-based capturing devices motivates the development of a non-contact blood pressure estimation method-Video-based Blood Pressure Estimation (V-BPE). We leverage the time difference of the blood pulse arrival at two different locations in the body (Pulse Transit Time) and the inverse relation between the blood pressure and the velocity of blood pressure pulse propagation in the artery to analytically estimate the blood pressure. Through statistical hypothesis testing, we demonstrate that Pulse Transit Time-based approaches to estimate blood pressure require knowledge of subject specific blood vessel parameters, such as the length of the blood vessel. We utilize a combination of computer vision techniques and demographic information (such as the height and the weight of the subject) to capture and incorporate the aforementioned subject specific blood vessel parameters into our estimation of blood pressure. We demonstrate the robustness of V-BPE by evaluating the efficacy of blood pressure estimation in demographically diverse, outside-the-lab conditions. V-BPE is advantageous in three ways; 1) it is non-contact-based, reducing the possibility of infection due to contact 2) it is scalable, given the ubiquity of video recording devices and 3) it is robust to diverse demographic scenarios due to the incorporation of subject specific information.
