MAINTAINING TRADITIONAL CULTURAL COMMUNICATION IN DIGITAL MEDIA (STUDY ON THE MAINTENANCE OF THE SORONG SERAH AJI KRAMA TRADITION ON COMMUNITY SOCIAL INTERACTION IN BAYAN, NORTH LOMBOK)
Sorong serah aji krama tradition is one of the wedding ceremonies series by the Sasak tribe that has been preserved to this day. This tradition is a form of traditional cultural expression of society represented through symbols on the means used that can influence the social interaction of the societies in Bayan in daily life, given that the symbols in the tradition are closely linked with how humans should act in society. Therefore, the issue discussed in this research is: (1) how does the process of sorong serah aji krama tradition in Bayan. (2) how is the symbolic interaction in the sorong serah aji krama tradition in Bayan? (3) What are the implications of symbolic interaction in the Sorong serah tradition over the social interaction of the societies in Bayan? This research object is a tradition of solid serah aji krama in Bayan, north Lombok, that will be researched using qualitative descriptive methods through observations, interviews, and documentation techniques of data collection. This research tries to find the symbolic form of interaction and the implication of symbolic interaction to the social interaction of society by using the symbolic interaction theory. The conclusion is this tradition begins with memulang, sejati selabar, tekang pengeraos, sorong serah aji krama, and ends with tekang pengeraos. Symbols that appear consist of gegawan, language, and behavior. The whole aspect of the symbol in the traditions relating to the godhead, nature, and social relations implicates the social interaction of indigenous societies
Is transperitoneal laparoscopic adrenalectomy for pheochromocytoma really more challenging? A propensity score-matched analysis
Purpose Minimally invasive surgery is the gold standard treatment for adrenal masses, but it may be a challenging procedure in the case of pheochromocytoma (PHEO). The aim of the present study is to report the results of transperitoneal laparoscopic adrenalectomy (TLA) in cases of PHEO in comparison to other types of adrenal lesions. Methods From 1994 to 2021, 629 patients underwent adrenalectomy. Twenty-two and thirty-five patients, respectively,
were excluded because they underwent bilateral and open adrenalectomy, leaving 572 patients for inclusion. Of these, 114 patients had PHEO (Group A), and 458 had other types of lesions (Group B). To adjust for potential baseline confounders, a propensity score matching (PSM) analysis was conducted. Results After PSM, 114 matched pairs of patients were identified from each group. Statistically significant differences were not observed when comparing the median operative time (85 and 90 min in Groups A and B, respectively, p = 0.627), conversion rate [6 (5.3%) in each group, p = 1.000], transfusion rate [4 (3.5%) and 3 (2.6%) in Groups A and B, respectively, p = 1.000], complication rate [7 (6.1%) and 9 (7.9%) in Groups A and B, respectively, p = 0.796), median postoperative hospital stay (3.9 and 3.6 days in Groups A and B, respectively, p = 0.110), and mortality rate [1 (0.9%) in each group, p = 1.000]. Conclusions Based on this analysis, the results of TLA for PHEO are equivalent to those of TLA for other types of adrenal
lesions, but the fundamental requirements are multidisciplinary patient management and adequate surgeon experience. Further prospective studies are required to draw definitive conclusions
ZrO2 Based materials as photocatalysts for 2-propanol oxidation by using UV and solar light irradiation and tests for CO2 reduction
Bare ZrO2, Ce doped ZrO2 and Er doped ZrO2 samples have been prepared by a hydrothermal process and have been used as photocatalysts for 2-propanol oxidation reaction in gas solid regime. Moreover, some preliminary tests have been carried out for CO2 reduction. The samples were physico-chemically characterized and both bare and doped ZrO2 based materials resulted active for oxidation and reduction reactions by using UV and solar irradiation. The reactivity results have been correlated with the compositional, structural and morphological features of the photocatalysts
Vis-NIR luminescent lanthanide-doped core-shell nanoparticles for imaging and photodynamic therapy
The preparation of smart Ln:ZrO2@SiO2 nanoplatforms with grafted photosensitizer (Rose Bengal) which couple optical imaging with photo-dynamic therapy (PDT) is presented. A careful control of the lanthanide dopant loading is considered to enhance the photoemission properties of the lanthanide ions (Er, Pr, Yb) inside the ZrO2 crystal structure. The nanosystem with the lowest lanthanide loading maintains the size, phase and morphology of pristine ZrO2 nanoparticles and exhibit the best performances in term of the overall luminescence properties. Upon functionalization with a silica shell to covalently bound Rose Bengal, a theranostic platform is prepared which is very efficient in singlet oxygen generation, as demonstrated by EPR and UV\u2013vis spectroscopy studies. Preliminary cell viability tests show that while both pristine and Ln doped ZrO2 nanoparticles do not exert cytotoxicity, neither upon illumination nor in dark condition, Rose Bengal grafted samples are able to significantly reduce cell viability under light exposure, thus confirming the high potential of these nanoparticles as PDT tools
The Overlap Between Binge Eating Behaviors and Polycystic Ovarian Syndrome: An Etiological Integrative Model
Studies indicate that Polycystic Ovarian Syndrome (PCOS) features (e.g. insulin instability, food cravings,overproduction of androgens and menstrual irregularities) are associated with increased appetite, impairedimpulse control and feelings of body dissatisfaction. Counter intuitively, binge eating behaviors have been shownto reinforce PCOS symptomatology, precipitating concurrently body dissatisfaction, weight gain, insulin instabilityand overproduction of androgens. The present systematic literature review aspires to investigate the relationshipbetween binge eating, in the broader context of eating disorder behaviors, and Polycystic Ovarian Syndrome(PCOS), taking into account shared characteristics between EDs (Eating Disorders) and PCOS. To address thisaim, the PRISMA guidelines are adopted. A total of 21 studies, which investigated the presence of binge eating inPCOS population and the presence of PCOS in EDs population, were synthesized. Findings suggested that anincreased prevalence of binge eating has been reported in women with Polycystic Ovarian Syndrome (PCOS);and that women suffering from BN (Bulimia Nervosa) and BED (Binge Eating Disorder) are more likely to displaypolycystic ovaries. Further research on their shared liability is required in order to inform more efficientprevention and treatment initiatives for populations presenting with comorbid features
Predicting postoperative hypocortisolism in patients with non-aldosterone-producing adrenocortical adenoma: a retrospective single-centre study
Background: Limited information exists on postoperative hypocortisolism and hypothalamus–pituitary–adrenal axis recovery in patients with adrenal incidentaloma following unilateral adrenalectomy. We evaluated frequency of postoperative hypocortisolism and predictors for recovery in non-aldosterone-producing adrenocortical adenoma patients after unilateral adrenalectomy. Methods: A retrospective analysis of 32 adrenal incidentaloma patients originally included in the ITACA trial (NCT04127552) with confirmed non-aldosterone-producing adrenocortical adenoma undergoing unilateral adrenalectomy from September 2019 to April 2023 was conducted. Preoperative assessments included adrenal MRI, anthropometrics, evaluation of comorbidities, adrenal function assessed via ACTH, urinary free cortisol, and 1 mg dexamethasone suppression test. ACTH and serum cortisol or Short Synacthen test were performed within 6 days, 6 weeks, 6 months, and a year after surgery. Results: Six days postoperative, 18.8% of patients had normal adrenal function. Among those with postoperative hypocortisolism, 53.8% recovered by 6 weeks. Patients with earlier adrenal recovery (6 weeks) had lower preoperative 1 mg dexamethasone suppression test (median 1 mg dexamethasone suppression test 76.2 [61.8–111.0] nmol/L vs 260.0 [113.0–288.5] nmol/L, p < 0.001). Univariate analysis showed preoperative 1 mg dexamethasone suppression test negatively related with baseline ACTH levels (r = − 0.376; p = 0.041) and negatively associated with the 6-week baseline (r = − 0.395, p = 0.034) and 30-min cortisol levels during Short Synacthen test (r = − 0.534, p = 0.023). Logistic regression analysis demonstrated preoperative 1 mg dexamethasone suppression test as the only biochemical predictor for 6-week adrenal recovery: ROC curve identified a 1 mg dexamethasone suppression test threshold of 131 nmol/L predicting 6-week recovery with 89.5% sensitivity and 72.7% specificity (AUC 0.87; 95% CI 66.9–98.7, p < 0.001). Other preoperative assessments (tumor size, ACTH levels and anthropometrics) were not associated with postoperative hypothalamus–pituitary–adrenal axis function, but the presence of diabetes was associated with a lower probability of recovery (OR = 24.55, p = 0.036). ACTH levels increased postoperatively in all patients but did not predict hypothalamus–pituitary–adrenal axis recovery. Conclusions: The preoperative 1 mg dexamethasone suppression test cortisol value and presence of diabetes are the only relevant predictor of hypothalamus–pituitary–adrenal axis recovery in patients with non-aldosterone- producing adrenocortical adenoma undergoing surgery, regardless other clinical and biochemical variables. Notably, pre- and postoperative ACTH levels did not predict hypothalamus–pituitary–adrenal axis recovery. These findings point towards the potential for saving resources by optimizing their allocation during follow-up assessments for patients with non-aldosterone-producing adrenocortical adenoma undergoing unilateral adrenalectomy
Data filtering in the readout of the CMS Electromagnetic Calorimeter
For an efficient data taking, the Electromagnetic Calorimeter (ECAL) data of the CMS experiment must be limited to 10\% of the full event size (1MB). Other requirements limit the average data size to 2kB per data acquisition link. These conditions imply a reduction factor of close to twenty on the data collected. The data filtering in the readout of the ECAL detector is discussed. Test beam data are used to study the digital filtering applied in the readout channels and a full detector simulation allows to estimate the energy thresholds to achieve the desired data suppression factor
Measurements of the and parameters of the matrix and perspectives
A review of the current status of the Cabibbo-Kobayashi-Maskawa matrix
() is presented and a special emphasis is put on the determination of
the and parameters. From this study it follows that, in the
Standard Model, the - oscillation frequency, ,
has to lie, with 68% C.L., between 6.5 ps and 15 ps, and is below
21 ps at 95% C.L. If the interest of measuring is
underlined, the importance of a precise determination of the B meson decay
constant, , is also stressed. It is proposed to obtain a precise value for
this parameter from an accurate measurement of , the D meson decay
constant, using results from lattice QCD to relate D and B hadrons. A future
Tau-Charm factory could accomplish this task. It is also shown that from the
present measurements, assuming the validity of the Standard Model, an already
accurate value of is obtained. Sofar no
constraint can be obtained on . The interest of having a direct
measurement of and at B-factories or at other
facilities is reminded. Finally constraints on SUSY parameters, in the
framework of a given model, obtained from a precise measurement of the CKM
matrix elements are analyzed.Comment: 32 page
Negotiated reorienting: a grounded theory of nurses’ end-of-life decision-making in the intensive care unit
Background
Intensive care units (ICUs) focus on treatment for those who are critically ill and interventions to prolong life. Ethical issues arise when decisions have to be made regarding the withdrawal and withholding of life-sustaining treatment and the shift to comfort and palliative care. These issues are particularly challenging for nurses when there are varying degrees of uncertainty regarding prognosis. Little is known about nurses’ end-of-life (EoL) decision-making practice across cultures.
Objectives
To understand nurses’ EoL decision-making practices in ICUs in different cultural contexts.
Design
We collected and analysed qualitative data using Grounded Theory.
Settings
Interviews were conducted with experienced ICU nurses in university or hospital premises in five countries: Brazil, England, Germany, Ireland and Palestine.
Participants
Semi-structured interviews were conducted with 51 nurses (10 in Brazil, 9 in
