Pig Tales: Forensic Taphonomy in Cozine Creek

The medicolegal community relies heavily upon determining the postmortem interval (PMI), the knowledge of how much time has elapsed since the person has died. Forensic taphonomy is the study of postmortem changes caused by outdoor environmental conditions that play a crucial role in decomposition rates. These include local temperatures, humidity, soil, plants, and insect and other scavenger activity. Minimal research exists examining the rate of surface decomposition in the Pacific Northwest climate. The purpose of this pilot study is to analyze the rate of decomposition in the microclimate of McMinnville, Oregon. A deceased juvenile pig (Sus scrofa) was placed in a secure cage in Cozine Creek on February 17, 2019. Data collection continues until May 2019 and includes daily observations, photographs, weather data, and insect collection for entomological assessment. Statistical analysis will be performed once all data is collected. Preliminary results suggest weather fluctuations and insect activity significantly influence decomposition rates. During the first four weeks, cold weather conditions did not favor decomposition: snow, low temperatures, and few insects. Once temperatures reached 13℃, a dramatic increase in insect activity and intensity was observed. Dermestid beetles, maggot masses, and blowflies were present, and within days a substantial increase in decomposition occurred

Synthèse de complexes de platine(II) avec des ligands mixtes amines et pyrimidine et caractérisation par spectroscopies infrarouge de résonance magnétique multinucléaire

Les complexes disubstitués du Pt(II) avec des ligands azotés sont connus depuis assez longtemps, mais la chimie de coordination du platine est encore peu développée. Il y a plusieurs publications sur la chimie des dérivés de la pyrimidine, à cause de l'importance biologique de ces molécules. Cependant, il y a peu de travaux dans la littérature sur la chimie de coordination de la pyrimidine non substituée. Quelques nouvelles méthodes ont été développées dans ce projet pour la préparation de complexes contenant des ligands mixtes, amine et pyrimidine. Plusieurs amines aliphatiques et cycliques possédant un encombrement stérique différent ont été choisies pour l'étude. Les nouveaux complexes de types cis- et trans- \ud Pt(amine)(pyrimidine)X₂ (X = Cl et I) et des dimères à pont pyrimidine de type trans, trans- X₂(amine)Pt(µ-pm)Pt(amine)X₂ ont été synthétisés et caractérisés par différentes techniques spectroscopiques. Les composés diiodo ont été synthétisés via l'intermédiaire du dimère à ponts iodo, I(amine)Pt(µ-I)₂Pt(amine)I et peut être utilisée pour la plupart des amines. La formation du dimère est très longue, car le produit initial \ud Pt(amine)₂I₂ est insoluble dans l'eau, tout comme le dimère. La réaction entre le dimère à ponts iodo et la pyrimidine en milieux aqueux dans les proportions 1 : 2 donne des composés de type Pt(amine)(pm)I₂ d'isomérie cis. Si les ligands sont encombrés, il y aura une isomérisation cis-trans. La deuxième méthode (X = Cl) implique la formation de l'intermédiaire K[Pt(amine)CI₃], qui a été préparé par 2 méthodes différentes, dont une est limitée à des amines encombrées. Le composé ionique réagit avec la pyrimidine dans les proportions 1 : 2 pour produire Pt(amine)(pm)CI₂. Le premier produit formé est l'isomère cis, mais il peut y avoir isomérisation si l'amine est encombrée. La même réaction dans des proportions 2 : 1 a conduit à des dimères à pont pyrimidine Cl₂(amine)Pt(µpm)Pt(amine)Cl₂ de géométrie trans,trans. Les complexes ont été caractérisés à l'état solide par spectroscopie infrarouge et en solution dans l'acétone par résonance magnétique multinucléaire (¹H, ¹³C et

Patients’ experiences and satisfaction with health care in the Salah Azaiez Institute of Cancer in Tunisia in 2020

Measurement of patient-centered care is a key step to ensure quality of care improvement. The aims of this study were to evaluate the experience of hospitalized patients of Salah Azaiez Institute (SAI) of Cancer of Tunisia in 2020 and to analyze factors associated to the global satisfaction. It was a cross-sectional study. The used questionnaire was derived from the Picker patient questionnaire. Factors associated to the global satisfaction were assessed using Chi-squared and Fisher’s exact tests. The present study concerned 200 inpatients of the SAI. The Cronbach’s α of the patient experience test (PPE-15) was of 0.82 indicating a good internal consistency. According to results of this study, only 38.5% of the patients were satisfied with their hospitalization. Perception of the quality of the received treatment was good to excellent for 57.0%. Regarding the global organization, 56.5% of the patients found it intermediate and 21.5% perceived it as bad. The highest scores among patient experience dimensions concerned the coordination of healthcare, the respect for patient preference and the physical comfort. However, lowest scores were attributed to the involvement of family and friends, the information and patient education and the emotional support. Unlike socio-demographic factors, patient experience and its dimensions was strongly associated to the global satisfaction. Further studies are recommended to explore patient experience dimensions and other determinants of patient satisfaction in Tunisia.

Change in the diet of sooty owls (Tyto tenebricosa) since European settlement: from terrestrial to arboreal prey and increased overlap with powerful owls

The current diet of the sooty owl (Tyto tenebricosa) was determined by analysing freshly regurgitated pellets collected beneath their roosting sites in East Gippsland, Victoria. Comparisons were then made with: (i) prehistoric and historic diet from bone deposits found in cave roosts, and (ii) diet of a sympatric owl species, the powerful owl (Ninox strenua). Sooty owls consumed a large array of terrestrial mammal species before European settlement, but only three terrestrial species were detected in their current diet, a reduction of at least eight species since European settlement. To compensate, sooty owls have increased their consumption of arboreal prey from 55% to 81% of their diet. Arboreal species are also a major component of the powerful owl diet and this prey shift by sooty owls has increased dietary overlap between these two species. Predation by foxes (Vulpes vulpes) and other feral species is likely to have reduced the amount of terrestrial prey available to sooty owls since European settlement. Investigation of changes in the diet of sooty owls may offer a unique monitoring system for evaluating the ability of fox-control strategies to influence increases in numbers of critical-weight-range mammals.<br /

The relationship between emotional intelligence, anxiety, and performance in physical education and sport students

Emotional intelligence (EI) has been recently the main target in research on sports psychology. The objectives of this study were to investigate the relation between self-report measures of emotional intelligence, pre-competitive anxiety, and performance among students during the physical education exam of the high school final year. This cross-sectional study was conducted on a sample of 350 students attending the physical education exam in the year 2021–2022. Analysis of the correlations between the scores of Emotional intelligence and anxiety showed that self-confidence was positively correlated with all dimensions of Emotional intelligence (Beta = 0.524; p = 0.000). Multivariate linear regression analysis showed that the most related items to performance were self-confidence in a positive direction (r = 0.56; p = 0.000) and negatively with somatic anxiety (r = −0, 39; p = 0.000). Considering the Emotional intelligence subscales, hetero-emotional management was significantly positively associated with performance (p = 0.000) however emotional perception was negatively correlated with performance (p = 0.003). These results demonstrate the importance of social and emotional learning programs for improving self-confidence and better management of emotions during physical education and sports

Multiple Primary Cancers in North Tunisia, 2000 - 2009

Aim: to evaluate and report the frequency, epidemiologic and antaomo -clinical features of patients who developed MPM from the data of North Tunisia Cancer Registry, during the period 2000-2009.Materials and methods: From a population of 53757 new patients of the North Tunisia National Cancer Registry database presenting new cases of cancers during the period 2000-2009 in North Tunisia, we collected and analyzed those with MPMTs. We used for MPMT the international IARC diagnosis criteria are published in ICD-O Third Edition. Results:  In the 53757 new cancer cases registered from 2000-2009, we collected 528 cases (1.0%) of MPM. Mean age at diagnosis of the 1st cancer was 61 years (22-99) and sex-ratio at  1.08 (275M/253F) while mean age at the 2nd cancer diagnosis was 62 years(29 to 99). Among the 528 cases, the most frequent 1st cancer site was breast in females (147 pts, 58.1%) and urinary tract for males (56 patients, 20.4%). In the 528 MPM cases, 321 (60.8%) were synchronous and 207 cases (39.2%) were metachronous tumors. The median time from 1st to 2nd cancer was 1.98 months (range 0-140). The most associated 1st-2nd cancer sites were breast in 110 patients (43.3%) in females and for males’ urinary tract -prostate cancers (45 patients, 16.3%). Conclusions: The coexistence of a synchronous or metachronous MPM is possible and have to be considered during pretreatment evaluation. A close follow-up should be recommended to detect second malignancies in patients treated for a 1st cancer.Keywords: Multiple primary malignancies , clinical features , North Tunisi
