RESUMO
SLC18B1 is a sister gene to the vesicular monoamine and acetylcholine transporters, and the only known polyamine transporter, with unknown physiological role. We reveal that Slc18b1 knock out mice has significantly reduced polyamine content in the brain providing the first evidence that Slc18b1 is functionally required for regulating polyamine levels. We found that this mouse has impaired short and long term memory in novel object recognition, radial arm maze and self-administration paradigms. We also show that Slc18b1 KO mice have altered expression of genes involved in Long Term Potentiation, plasticity, calcium signalling and synaptic functions and that expression of components of GABA and glutamate signalling are changed. We further observe a partial resistance to diazepam, manifested as significantly lowered reduction in locomotion after diazepam treatment. We suggest that removal of Slc18b1 leads to reduction of polyamine contents in neurons, resulting in reduced GABA signalling due to long-term reduction in glutamatergic signalling.

Background: Previous differences in guideline recommendation strength for CYP2C19 intermediate metabolizers may have limited genotype (PGx)-optimal post-percutaneous coronary intervention antiplatelet prescribing. Results: In this single-center retrospective observational cohort study of CYP2C19 intermediate metabolizers, patients prescribed PGx-optimal therapy were younger and less likely on anticoagulation (2 vs 12%; p = 0.006). More patients prescribed PGx-optimal therapy possessed commercial insurance (36 vs 7%; p < 0.001), which was a predictor for PGx-optimal selection (OR: 6.464; 95% CI: 2.386-17.516; p < 0.001). Conclusion: Anticoagulation use was significantly associated with clopidogrel use (OR: 0.138; 95% CI: 0.026-0.730; p = 0.020). No statistical difference in composite major adverse cardiovascular events (5 vs 14%; p = 0.173) or bleeding (8 vs 6%; Not significant) was observed between PGx-optimal and PGx-suboptimal therapy.
Not all CYP2C19 intermediate metabolizers undergoing PCI are prescribed genotype-optimal P2Y12 antiplatelet therapy. Commercial insurance and no anticoagulant were found to be associated with ticagrelor and prasugrel prescribing in this population.
RESUMO
BACKGROUND: There is a wide range of commercial and custom-made devices available for the treatment of trismus (restricted jaw opening). They are used often in conjunction with a prescribed exercise program with the aim of improving maximal inter-incisal opening (MIO). This study compared the efficacy (MIO and patient reported outcome results), adverse events, consumer experience and cost of the different types of devices available. METHODS: Four databases were searched between the years 2001-2021 using the terms 'trismus' and 'device'. Two independent authors assessed each paper for inclusion, then conducted a quality analysis. RESULTS: Thirty-two studies met the criterion required for inclusion. The majority (n = 27) were in the context of established trismus, where the remaining five used the device preventatively. The trismus device improved MIO in 23 of the rehabilitation programs (pooled mean MIO increased by 9.5 mm in the intervention arm compared to 2.4 mm for controls; p = 0.0001). Improved MIO was not observed in the prevention studies. The Therabite ® was the most common trismus device investigated and with a mean increase in MIO of 10.0 mm and cost of $499AUD. Forces applied by trismus devices were regulated by the perception of pain experienced by the patient, rather than a prescribed force by the treating health professional. Despite this guidance, several adverse events occurred (n = 8), including mandibular and molar fractures. Barriers experienced by consumers included pain, ill-fitting mouthpiece, adverse events, exercise adherence and cost. CONCLUSION: Trismus devices which use the application of force to the jaw can improve the MIO of patients with established trismus. However, their role is unproven in the setting of trismus prevention during radiotherapy and several significant barriers such as cost, exercise adherence and safety concerns have been demonstrated for the intervention setting.

Purpose@#Patients with cancer are particularly vulnerable to coronavirus disease (COVID). Transportation barriers made travel to obtain medical care more difficult during the pandemic. Whether these factors led to changes in the distance traveled for radiotherapy and the coordinated location of radiation treatment is unknown. @*Materials and Methods@#We analyzed patients across 60 cancer sites in the National Cancer Database from 2018 to 2020. Demographic and clinical variables were analyzed for changes in distance traveled for radiotherapy. We designated the facilities in the 99th percentile or above in terms of the proportion of patients who traveled more than 200 miles as “destination facilities.” We defined “coordinated care” as undergoing radiotherapy at the same facility where the cancer was diagnosed. @*Results@#We evaluated 1,151,954 patients. There was a greater than 1% decrease in the proportion of patients treated in the Mid-Atlantic States. Mean distance traveled from place of residence to radiation treatment decreased from 28.6 to 25.9 miles, and the proportion traveling greater than 50 miles decreased from 7.7% to 7.1%. At “destination facilities,” the proportion traveling more than 200 miles decreased from 29.3% in 2018 to 24% in 2020. In comparison, at the other hospitals, the proportion traveling more than 200 miles decreased from 1.07% to 0.97%. In 2020, residing in a rural area resulted in a lower odds of having coordinated care (multivariable odds ratio = 0.89; 95% confidence interval, 0.83–0.95). @*Conclusion@#The first year of the COVID pandemic measurably impacted the location of U.S. radiation therapy treatment.
RESUMO
Objective@#The current study aims to explore precipitating and social risk factors for internet addiction (IA) in university undergraduate students, and to provide evidence for interventions and the early prevention of IA in different genders. @*Methods@#Four thousand eight hundred and fifty-eight college sophomores completed an online survey on their internet use-related behaviours and social risk factors. @*Results@#We found that more male (8.3%) than female students (5.4%) had moderate and severe IA. The main online activity in the moderate and severe IA groups was online gaming in males and online streaming in females. Roommates engaging in similar internetbased entertainment was a risk factor of IA only for males, while not being in a romantic relationship was a risk factor of IA for females only. Infatuation with the internet before college and adjustment problems for college life were shared risk factors for both genders in the mild and moderate IA groups. @*Conclusion@#IA was a common phenomenon in college students with shared and unique precipitating and social risk factors in males and females. The gender-sensitive risk factors for IA warranted earlier and individualized intervention and prevention strategies for IA in this population.

RESUMO
Purpose@#From the perspective of positive psychology, our study aimed to explore depressive symptomsand psychological well-being among Chinese nurses, as well as analyze the impacts of characterstrengths, self-efficacy and social support on the mental health of nurses. @*Methods@#A cross-sectional and descriptive design using five self-reported questionnaires was used toinvestigate a cohort of 4238 nurses during 2018. A structural equation modeling analysis was used toverify a hypothetical model linking character strengths, self-efficacy, social support, depressive symptoms,and psychological well-being. @*Results@#The prevalence of depression among this cohort of Chinese nurses was 58.1%. The mean scoresfor caring, inquisitiveness, and self-control were 19.93 (SD = 2.82), 15.94 (SD = 3.00), and 16.34(SD = 2.95), respectively. The hypothesized model was a good fit of the data (x2/df = 1.77, p = .183, rootmean square error of approximation = 0.04, goodness of fit index = 1.00, comparative fit index = 1.00,TuckereLewis index = 1.00). Except for the path from self-control to depression, the other hypotheticalpaths investigated were statistically significant. @*Conclusion@#Character strengths were directly and positively associated with psychological well-being.Inquisitiveness was the strongest direct protective factor for depression. In addition, characterstrengths indirectly alleviated depression and increased psychological well-being through mediatingvariables of social support and self-efficacy. This study should alert nurse managers that more attentionshould be paid to the character strengths and mental health of nurses. This study provides evidence forinterventions based on character strengths as a management strategy to support the mental health ofnurses.

RESUMO
BACKGROUND/AIMS: It is now recognised that gastric dysrhythmias are best characterised by their spatial propagation pattern. Hyperglycemia is an important cause of gastric slow wave dysrhythmia, however, the spatiotemporal patterns of dysrhythmias in this context have not been investigated. This study aims to investigate the relationship between hyperglycemia and the patterns of dysrhythmias by employing high-resolution (multi-electrode) mapping simultaneously at the anterior and posterior gastric serosa. METHODS: High-resolution mapping (8 × 16 electrodes per serosal) was performed in 4 anesthetized hounds. Baseline recordings (21 ± 8 minutes) were followed by intravenous injection of glucagon (0.5 mg per dose) and further recordings (59 ± 15 minutes). Blood glucose levels were monitored manually using a glucose sensing kit at regular 5-minute intervals. Slow wave activation maps, amplitudes, velocity, anisotropic ratio, and frequency were calculated. Differences were compared between baseline and post glucagon injection. RESULTS: Baseline slow waves propagated symmetrically and antegrade. The blood glucose levels were increased by an average of 112% compared to the baseline by the end of the recordings. All subjects demonstrated elevated incidence of slow wave dysrhythmias following injection compared to the baseline (48 ± 23% vs 6 ± 4%, P < 0.05). Dysrhythmias arose simultaneously or independently on anterior and posterior serosa. Spatial dysrhythmias occurred before and persisted after the onset and disappearance of temporal dysrhythmias. CONCLUSIONS: Infusion of glucagon induced gastric slow wave dysrhythmias, which occurred across a heterogeneous range of patterns and frequencies. The spatial dysrhythmias of gastric slow waves were shown to be more prevalent and persisted over a longer period of time compared to the temporal dysrhythmias.

BACKGROUND/AIMS: Small intestine motility is governed by an electrical slow wave activity, and abnormal slow wave events have been associated with intestinal dysmotility. High-resolution (HR) techniques are necessary to analyze slow wave propagation, but progress has been limited by few available electrode options and laborious manual analysis. This study presents novel methods for in vivo HR mapping of small intestine slow wave activity. METHODS: Recordings were obtained from along the porcine small intestine using flexible printed circuit board arrays (256 electrodes; 4 mm spacing). Filtering options were compared, and analysis was automated through adaptations of the falling-edge variable-threshold (FEVT) algorithm and graphical visualization tools. RESULTS: A Savitzky-Golay filter was chosen with polynomial-order 9 and window size 1.7 seconds, which maintained 94% of slow wave amplitude, 57% of gradient and achieved a noise correction ratio of 0.083. Optimized FEVT parameters achieved 87% sensitivity and 90% positive-predictive value. Automated activation mapping and animation successfully revealed slow wave propagation patterns, and frequency, velocity, and amplitude were calculated and compared at 5 locations along the intestine (16.4 +/- 0.3 cpm, 13.4 +/- 1.7 mm/sec, and 43 +/- 6 microV, respectively, in the proximal jejunum). CONCLUSIONS: The methods developed and validated here will greatly assist small intestine HR mapping, and will enable experimental and translational work to evaluate small intestine motility in health and disease.

The objective of this project was to study the attitude and general knowledge of Medical students at Khon Kaen University (KKU), Thailand concerning cigarrette smoking. The study examines the relationship between knowledge, attitude to smoking and smoking habits. Certain socio-economic factors known to infulence smoking behaviour were controlled in this study. The population used in this research was the medical students studying in the first and fifth years in the faculty of Medicine, Khon Kaen University, Thailand during the academic year 1987-1988. A total number of 145 responses were returned out of possible 192. The questionnaires were analysed and the chisquared test was used to test the hypothesis. The study shows that most medical students are nonsmokers with less females smoking than males. A relationship was found between knowledge of the effects of smoking and year of study. Fifth year students have greater knowledge than the first years. A relationship was also found between attitude and year of study; the first year medical students had a better attitude than the fifth years. In addition, it was discovered that some specific combinations of attitude and opinion have a relationship with smoking habits (non-smokers, daily and occasionally smokers) at a significance level of P
RESUMO
Biomechanical analysis of the configuration changes of the patella was studied. Normal patellar tracking in the sagittal plane was obtained by recording and digitizing knee extension of six healthy adults with fluoroscopy. Based on the digitized data, the changes of patellar thickness were simulated by translating its axis and its forward and backward tilting by rotation in the sagittal plane. We assumed that the extensor moment remained constant before and after the patellar configuration was changed. Therefore, using a balance beam, model equilibrium was reached, after each simulated change of patellar configuration, of the forces involved in the extensor mechanism: the quadriceps muscle force, tension of patella tendon and patellofemoral joint reaction force. The results revealed that when the patellar thickness decreased, quadriceps force increased but patellofemoral joint reaction force decreased and the reverse was seen when the patella thickened. Backward tilting of the patella decreased quadriceps force and patellofemoral joint reaction force and increased the patella tendon/quadriceps force ratio, which produced a better mechanical advantage of force transmission of patella. The reverse was seen in forward tilting. These results suggest that the patella could be tilted backward for the older patient undergoing total knee replacement. For younger patients with relatively strong quadriceps musculature, we suggest that the patellar thickness could be decreased to reduce the patellofemoral joint reaction force so as to reduce the chance of failure of the patella prosthesis.
RESUMO
OBJECTIVE: To evaluate the role of active and passive muscle forces in the failure mechanism of stimulated muscle. DESIGN: An in vivo rabbit model. BACKGROUND: Eccentric contractions can result in a greater incidence of muscle injury. However, the relative role of the active and passive muscle force in the failure mechanism of the activated muscle is not well elucidated. METHODS: After anaesthesia, New Zealand white rabbits were fixed in a frame on a materials testing machine. The triceps surae muscle-tendon units were passively stretched to rupture with our without continuous nerve stimulation. The force and muscle length were simultaneously recorded. Active muscle force, passive muscle force, and ratio of the active to passive muscle were calculated and depicted against strain. RESULTS: The results showed that the mean maximal passive force of triceps surae muscle was 293.1 N at a strain of 38%. The mean peak active muscle force was 21.5 N at a strain of 21%. The ratio of active to passive muscle force reached its peak first, followed by the active muscle force, and then the passive muscle force. The ratio of active to passive muscle force at the peak total force was only 3.3%. CONCLUSIONS: The stimulated muscle can exert its maximal response at extreme physiological extension. Injury of the stimulated muscle is caused mainly by passive muscle force.
RESUMO
<p><b>OBJECTIVE</b>To investigate the antioxidant and cytotoxic properties of five diarylheptanoids (1-5) isolated from the rhizomes of Zingiber officinale.</p><p><b>METHOD</b>Various models such as scavenging superoxide anions and 1,1-diphenyl-2- picrylhydrazyl (DPPH) radicals, inhibiting lipid peroxidation, as well as protecting of rat pheochromocytoma (PC12) cells induced by hydrogen peroxide (H2O2) were employed to assay the antioxidative effects of the diarylheptanoids.

<p><b>OBJECTIVE</b>To determine the benefit of carotid endarterectomy (CEA) for stroke prevention by reviewing the early and late outcomes of Hong Kong Chinese patients undergoing CEA who have a high reported incidence of intracranial atherosclerotic disease (IAD).</p><p><b>METHODS</b>Fifty-nine Chinese patients underwent 62 CEA. There were 48 males and 11 females, with a mean age of 70 +/- 7 years (range: 52 - 86 years). Twenty-one CEA (34%) were performed for asymptomatic disease. Duplex scan was the primary tool of evaluation prior to surgery. Preoperative angiography was done in 36 instances (58%). All CEA were performed under general anaesthesia with routine intraoperative shunting. The arteriotomy was closed primarily in all patients except three. Patients were followed up regularly with six-monthly Duplex scan surveillance.</p><p><b>RESULTS</b>There were 2 perioperative neurological events consisting of one transient ischemic attack and one minor stroke. There was no operative mortality or major morbidity such as bleeding or cranial nerve injury. Mean hospital stay was 6.5 +/- 4 days (range: 3 - 26 days). The patients were followed up for a mean interval of 24 +/- 17 months (range: 1 - 57 months). Seven patients died during follow-up and subsequent neurological events occurred in 5 patients, including 2 fatal strokes. The 3-year survival, freedom from stroke and stroke free survival were 86%, 87% and 83%, respectively. One recurrent stenosis of 80% was detected on follow-up Duplex scan.</p><p><b>CONCLUSIONS</b>Despite a high incidence of IAD, CEA in Hong Kong Chinese patients is associated with acceptable perioperative morbidity and mortality with satisfactory long-term efficacy in stroke prevention.</p>

This retrospective study evaluated the outcomes of patients who underwent unprotected left main coronary artery [ULMCA] percutaneous coronary intervention [PCI] with different types of drug-eluting stents [DES]. The standard of care for patients with ULMCA is coronary artery bypass surgery. However, current guidelines recommend PCI in clinical conditions where there is an increased risk of adverse surgical outcomes. Clinical outcomes of patients undergoing ULMCA PCI with different types of drug-eluting stents [DES] are unknown. Data from a multicenter international registry, which included 239 consecutive patients from four institutions who ULMCA PCI with DES, were collected. There were 42 patients receiving paclitaxel-eluting stent [PES], 158 patients receiving sirolimus-eluting stent [SES], and 39 patients receiving everolimus-eluting stent [EES]. There was no statistical difference in major adverse cardiovascular events, cardiac death, myocardial infarction, target lesion revascularization, and stent thrombosis among PES, SES, and EES at 30 days and 1 year. There are no differences in clinical events among patients receiving PES, SES, and EES for ULMCA disease

Although there has been much discussion on inclusive practices, there is a need for more research on the perceptions of educators and parents about inclusive educational placements for intellectually disabled [ID] children. In this study, the perceptions of parents and teachers about the quality of educational services ID children receive; the benefits of inclusion practices and the treatment and acceptance of ID students were surveyed. A total of 750 parents and teachers from both special education and mainstream schools participated. All respondents indicated that there may be mutual benefits for ID and non-ID children arising from inclusion practices. However, the respondents' perceptions differed regarding the quality of educational services that ID children were receiving and the treatment and acceptance of these students in regular classrooms. Implications for the development and implementation of inclusive educational placements are discussed
