Impacts of a Mindful Eating Intervention on Healthy Food-related Behaviors and Mindful Eating Practices among Elementary School Children

Background and Purpose: Mindful eating approaches encourage paying purposeful attention on purpose to body sensations, thoughts and emotions related to food and eating. The current study examined the impact of Foodie U, a mindful-eating intervention, among elementary school children and their families. Methods: A total of 178 third- through fifth grade children and their parents in rural northern California participated in Foodie U. The quasi-experimental intervention included two parent workshops, six monthly in-class mindful eating lessons and activities, and mindful eating activities to complete at home. Outcomes included food consumption, mindful-eating practices, emotional eating, and cue-elicited food craving among children. Results: T-tests and linear regression results revealed that students who received the intervention reported significantly less intense craving responses, especially among female and Hispanic students. The impact of the intervention on food craving was significant after controlling for gender and ethnicity. Fruit consumption significantly increased among intervention students. The mindful eating awareness score significantly increased among female intervention students. Conclusions: Foodie U had a positive impact on some food-related behaviors among elementary school-aged students. Further research is needed to examine the effectiveness of each element of the intervention.
Association between the usage of Smartphone as the risk factor for the prevalence of upper extremity and neck symptoms among University students: A cross - sectional survey based study.

Background: The usage of smartphone played a significant role in everyday life especially among students. Concern has risen universally of possible musculoskeletal symptoms among smartphone users due to excessive use. Objective: To determine the prevalence of neck and upper extremity symptoms among University students who were using a smartphone. Methods: A cross – sectional survey using self – administered questionnaires were conducted on 250 undergraduate students from one of the leading university in Malaysia. Six out of 250 participants (2.4%) were excluded as they were not a smartphone user. The number of participants from two faculties, namely Faculty of Medical and Health Sciences (FMHS) and Faculty of Accountancy and Management (FAM) were determined with stratified random sampling using Kish Leslie sample size formula. Results: The frequency of six measures of smartphone use was ranked from highest to lowest in order: Internet browsing and E – learning (85.20%), making phone calls (78.30%), texting and emails (77.00%), music, video, and pictures (75.40%), gaming (51.20%) and scheduling (32.80%). Out of 244 participants, 49 (20.1%) of the smartphone users were found to have developed some degree of upper extremity and neck symptoms. The prevalence of neck symptoms was the highest with 44 (18.03%) sufferers, followed by right shoulder symptoms (13.93%) and left shoulder symptoms (11.07%). Despite the symptoms experienced, only 5 (10.20%) participants received treatment while 30 participants (61.22%) claimed that they continued using the smartphone during these episodes. Conclusion: It is postulated that there is a positive relationship between smartphone usage and prevalence of upper extremity and neck symptoms. Recommendation: It is high time to disseminate the basic education on proper usage related to ergonomics is warranted to the university students to increase their awareness.

An 18 × 18-cm2 prototype has been fabricated and tested, showing a good matching with the simulations. The measured gains are 28.5 dBi at 20 GHz and 32.25 dBi at 30 GHz.
Factors Influencing the Fear of Needles among Students of Medicine and Pharmacy

Summary Fear of needles can significantly limit professional and social functioning of a person, and is highly prevalent in general population (4%). The aim of our study was to reveal risk factors that are associated with fear of needles among healthy university students of medicine and pharmacy. The study was of a cross-sectional type. In total, 301 students of medicine or pharmacy (82% female and 18% male) attending from 1st to 5th year of study were surveyed at the Faculty of Medical Sciences, University of Kragujevac, Serbia. The students were surveyed using a questionnaires (scales) for assessing the fear of needless, a visual analog scale for self-assessment intensity of the fear of needless, and a general questionnaire with questions about socio-demographic characteristics of the participants. Using a score on the scales as out-come variables, multiple regressions were employed to reveal factors that may influence the fear of needles. Average values of Blood/Injection Fear Scale, Injection Phobia Scale-Anxiety and Medical Avoidance Survey scores were 7.89 ± 9.48, 4.46 ± 5.18 and 89.95 ± 12.73, respectively. The following factors affected significantly the score of the scales: course of study, chronic disease in the family, fear of a dentist, smell of the room phobia, sound phobia, score on the Beck’s anxiety scale and fear of a situation when medical staff give an injection. The presence of chronic disease in the family was a protective factor, while the other six factors were contributing to the fear of needles. Fear of needles is more prevalent among the students of pharmacy than among the students of medicine. It is less frequent among students with chronic disease in their family, while fear of dentist, smell of the room phobia, sound phobia, general anxiety and fear from the situation when medical staff give an injection are all factors that predispose students of medicine or pharmacy to develop fear of needles.
Case Report: Angiomyolipoma of the cervix – report of a rare entity

Angiomyolipoma (AML) is a mesenchymal neoplasm seen usually in the kidney. Few cases of extra renal AML have been documented in various organs including the female genital tract, where the uterus is the most common site. To the best of our knowledge, only 4 cases of AML in the cervix have been reported in the literature. Association of AML with tuberous sclerosis is well known. Presently AML is included in the spectrum of disease entities called PEComa. We report a case of AML without tuberous sclerosis arising from the uterine cervix, which has to be differentiated from lipoleiomyoma. Keywords: Angiomyolipoma; Uterine cervix; PEComas; Uterine tumor
Evaluation of Genetic and Biochemical Factors in Patients with Acute Coronary Syndrome

Introduction: The cardiovascular diseases are the principal cause of death worldwide and a public health problem in Colombia. From the cardiac related illnesses, the most frequent is the Acute Coronary Syndrome (ACS). One of its risk factor is high plasma levels of homocysteine. The enzyme Paraoxonase 1 (PON1) hydrolyzes Homocysteine-thiolactone, producing homocysteine, avoiding damage to endothelium related to Homocysteine-thiolactone. Two genetic variants in PON1 gene have been associated with levels of homocysteine and acute coronary syndrome. Objective: to determine the relationship between the polymorphisms Q192R and L55M from gene PON1 and the levels of homocysteine, HDL, apo A-1 and the enzymatic activity of Paraoxonase I in patients who suffered acute coronary syndrome. Methods: sixteen unrelated patients with Acute Coronary Syndrome (ACS) and sixteen healthy controls were enrolled. The paraoxonase activity, levels of homocysteine, HDL and apo A-1 were assessed. The DNA polymorphism analysis was performed using Polymerase Chain Reaction (PCR) and digestion with restriction enzymes. Results: levels of homocysteine are higher in cases (p<0.0001) and the genotypes 192RR and QR are associated with higher levels of homocysteine (p=0.0234). Conclusion: polymorphisms in PON1 gene could be related to homocysteine levels in Acute Coronary Syndrome patients.

Interaction of anaesthetics with the carotid body glomus cell and the background potassium channel response to hypoxia

This thesis investigates the role anaesthetics play in the depression of the acute hypoxic and hypercapnic ventilatory response. Particular attention is paid to TASK (TWIK related acid sensitive potassium) channels that are known to be sensitive to both hypoxia and the volatile anaesthetics. After chapters relating to a general introduction and methods, chapter 3 describes studies into the hypoxic and hypercapnic responses of mice with genetic ablation of TASK 1 and/or TASK 3. By using whole animal unrestrained plethysmography, it was demonstrated that any loss of TASK channels resulted in a depression of ventilatory responses to hypoxia and hypercapnia. In isocapnic hypoxia, there is a genotype specific depression by anaesthetics of the remaining AHVR, depending on whether halothane or isoflurane is inspired. Chapter 4 establishes that propofol depresses the chemosensory responses of carotid body glomus cells. Using ratiometric flurimetry to measure the intracellular calcium concentration in isolated neonatal rat glomus cells, it was demonstrated that propofol depresses the normal cellular response to both hypoxia and hypercapnia. Using pharmacological modulators of GABA and nAChR, and single channel patch clamp electrophysiology of TASK, it is apparent that this depression is independent of these candidate mechanisms. Chapter 5 describes the effects of the anaesthetic dexmedetomidine at two levels of the hypoxic chemoreflex arc in rodents. Neither isolated rat glomus cells, nor unrestrained mice show significant depression of hypoxic responses when dexmedetomidine is present. Chapter 6 illustrates the potential role for specific antagonism of TASK channels in stimulating the carotid body. Two TASK channel blockers, A1899 (TASK 1 antagonist) and PK-THPP (TASK 3 antagonist) are shown to cause a significant influx of calcium into isolated glomus cells, and an augmentation in the glomus cell response to hypoxia, which persists in the presence of isoflurane. Overall, this thesis provides evidence that both TASK 1 and TASK 3 channels are essential for normal hypoxic chemosensitivity. It has extended the knowledge that anaesthetics depress glomus cell chemosensation, by demonstrating that propofol too causes this effect. It also proposes that dexmedetomidine may have greater utility in sparing of ventilatory reflexes. By selectively blocking TASK channels, glomus cells can be stimulated, and exploiting this mechanism would be useful in minimising anaesthetic-induced depression of ventilation.
What is Real and What is Not in the Global FDI Network?

Macro statistics on foreign direct investment (FDI) are blurred by offshore centers with enormous inward and outward investment positions. This paper uses several new data sources, both macro and micro, to estimate the global FDI network while disentangling real investment and phantom investment and allocating real investment to ultimate investor economies. We find that phantom investment into corporate shells with no substance and no real links to the local economy may account for almost 40 percent of global FDI. Ignoring phantom investment and allocating real investment to ultimate investors increases the explanatory power of standard gravity variables by around 25 percent.
Thwarting Adversaries with Randomness and Irrationality

Distributed systems are ubiquitous today: from the Internet used by billions of people around the world to the small scale IoT devices. With this rapidly increasing need to perform computation at scales larger than ever before, comes the need to ensure resilience to adversarial failures so that these systems can continue to behave as intended even when some malicious tampering happens. In this dissertation, we explore the power of randomness and the difficulty of rationally approximating the Golden Ratio to thwart adversarial behavior in two different problems in distributed computing: interactive communication and robust collaborative search. While randomness helps with unpredictable behavior which protects against adversarial tampering on the communication channels, the Golden Ratio offers uniform spreading which helps locate the target faster. For interactive communication among a group of nodes, we consider an omniscient adversary that flips an unknown number of bits on the channels between the nodes. We first provide an algorithm for only a single message that needs to be sent between two parties. We then extend our result to the general multiparty case, where our algorithm efficiently simulates any asynchronous noise-free protocol into a robust synchronous protocol, sending asymptotically optimal number of bits. Next, we discuss an algorithm for a multi-agent collaborative search on a plane for a target, when the agents can experience adversarial crash failures. This is the vii well-known Ants Nearby Treasure Search (ANTS) problem, introduced by Feinerman et al earlier this decade. While the problem they consider is only for the case of a point target and no failures, we consider foraging for an adversarially placed shape of unknown diameter, located at an unknown distance, where certain agents can experience crash failures at any point during the algorithm. We provide lower bounds for this problem and prove that our solution is optimal for the class of spoke algorithms – ones in which the agents move radially away and back to the nest. Our result is one of the first to provide scalable robustness guarantees in this setting. Our key tool is here to exploit the difficulty in rationally approximating the Golden Ratio to spread out the search trajectories for the agents. This not only ensures that the shape is located faster, but we also obtain resilience against arbitrary many crash failures in the system. Finally, we discuss a problem closely related to the ANTS problem, called Central Place Foraging (CPF). In this problem, the searchers search in a bounded arena around a nest and are allowed communication through pheromones. Moreover, the distribution of food around the nest is assumed to follow some probability distribution, and biological factors like the effects of depletion of food resources and preferential search in areas where food was previously found are important factors. We analyze three well known algorithms for this problem and report their expected runtimes. We validate our claims using experimental simulations in ARGoS.
Planktic Foraminiferal Test Size and Weight Response to the Late Pliocene Environment

Atmospheric carbon dioxide (pCO2atm) is impacting the ocean and marine organisms directly via changes in carbonate chemistry and indirectly via a range of changes in physical parameters most dominantly temperature. To assess potential impacts of climate change on carbonate production in the open ocean, we measured size and weight of planktic foraminifers during the late Pliocene at pCO2atm concentrations comparable to today and global temperatures 2 to 3 °C warmer. Size of all foraminifers was measured at Atlantic Ocean Deep Sea Drilling Project (DSDP) Site 610, Ocean Drilling Program (ODP) Site 999, and Integrated Ocean Drilling Program (IODP) Site U1313. Test size was smaller during the Pliocene than in modern assemblages under the same environmental conditions. During the cold marine isotope stage (MIS) M2, size increased at Site 999, potentially linked to intensified stratification of the surface ocean in response to the closure of the Central American Seaway. At Site U1313, test size tracks the warming throughout the late Pliocene. Size‐normalized weight (SNW) of Globigerina bulloides at Site U1313 decreased during warmer temperature intervals. SNW of Globigerinoides ruber (white) at Site 999 displays high‐frequency variability not correlated to temperature. Yet during the glacial period within MIS M2, test weight was higher during higher temperatures. Our results support studies in the modern ocean, which challenge the view that carbonate chemistry is the primary driver for calcification. To better understand processes driving changes in SNW, computer tomography was used to quantify calcite to volume ratios. During interglacial periods, lower calcite volume but higher test volume suggests less suitable conditions for calcification. As this signal is not evident in SNW, subtle changes in calcification might not be observed by the weight‐based method.
Perineural steroid injections around ilioinguinal, iliohypogastric, and genitofemoral nerves for treatment of chronic refractory neuropathic pain: A retrospective study

ABSTRACT Background: Perineural local anaesthetic and steroid injections around ilioinguinal (II), iliohypogastric (IH), and genitofemoral (GF) nerves are often performed to treat chronic refractory neuropathic pain in the lower abdomen and groin, but there is a lack of published data on outcomes of these interventions. Aims: The objective of this retrospective study was to evaluate analgesic outcomes of ultrasound-guided II, IH, and GF nerve blocks in patients with chronic neuropathic pain in the lower abdominal wall and groin. Methods: Analgesic outcomes were assessed at 6 weeks after injections and patients were classified as “responders” if the numerical rating scale for pain score reduced by 30% or more. Variables analyzed for impact on outcomes included demographics, intensity of pain and duration, etiology, dose of opioid, presence of anxiety, depression, and diabetes mellitus. Results: In this cohort of 54 patients with severe baseline pain who had failed to receive analgesic benefit from recommended first- and second-line medications for neuropathic pain, 30 patients had history of surgery and 24 had pain secondary to visceral inflammatory pathologies. Twenty-five (46.3%) patients were identified as responders. A majority of the patients in this cohort had pain for more than one year. There was a higher incidence of diabetes mellitus in nonresponders compared to responders but the difference was not significant (14% and 0%, respectively; P = 0.115). Conclusions: Ultrasound-guided perineural steroids can ameliorate chronic refractory abdominal wall and groin neuropathic pain in patients who have failed to respond to conventional medical management at 6 weeks after the procedures.
