Studiul Ć®Či propune reevaluarea
atitudinii terapeutice Ć®n cazul ulcerului gastroduodenal hemoragic, cu stabilirea unor criterii de gravitate Ć®n care intervenČia chirurgicalÄ se impune.
Material si metode: Studiul analizeazÄ retrospectiv un numÄr de 337 de pacienČi cu diagnosticul de ulcer gastroduodenal hemoragic, internaČi Či
trataČi Ć®n Clinica Chirurgie a Spitalului Clinic de UrgenČÄ āSf. Pantelimonā, Ć®n decurs de 3 ani, Ć®n perioada ian. 2008 ā dec. 2010. S-au analizat datele
din foile de observaČie, protocoale operatorii, rezultate histopatologice. Rezultate: Majoritatea hemoragiilor digestive superioare de cauzÄ ulceroasÄ au
fost rezolvate cu tratament medicamentos (278 bolnavi). La restul de 59 de pacienČi a fost necesar un tratament chirurgical, dintre care la 43 pacienČi
intervenČia a fost impusÄ de pierderea de sĆ¢nge ce ameninČÄ viaČa, iar la 16 pacienČi intervenČia a fost impusÄ de criteriile de gravitate/criteriile prognostice: repetarea sĆ¢ngerarii la scurt timp, criterii endoscopice de gravitate, grupa de sĆ¢nge rarÄ, etc. La 32 de bolnavi s- au practicat rezecČii gastrice
subtotale cu diferite tipuri de anastomozÄ iar Ć®n 27 de cazuri s-a practicat ulceroexcizie Či hemostaza in situ. Concluzii: EvoluČia ascendentÄ a terapiei
farmacologice Či endoscopice a scÄzut semnificativ necesitatea intervenČiilor chirurgicale. IntervenČia chirurgicalÄ rÄmĆ¢ne mijloc terapeutic util Ć®n

development of criteria recommending surgery. Material and methods: The study evaluates 337 patients diagnosed with gastroduodenal ulcer, complicated
with bleeding, between January 2008 and December 2010. Data was collected from patient charts, operative recordings, histopathological results. Results: The
majority of upper GI bleeding, following the development of an ulcer was managed with medical therapy (278 patients). The remaining 59 patients required
surgery, imposed in 43 cases by life threatening blood loss, and in 16 by gravity/prognostic criteria: frequent recurrence of bleeding, endoscopic gravity criteria,
rare blood group, etc. Subtotal gastrectomy with various types of anastomosis was performed in 32 cases while in the remaining 27 cases we performed the
excision of the lesion and in situ hemostasis. Conclusions: The evolution of pharmacological and endoscopic management significantly reduced the necessity
for surgery. Surgery remains a useful therapeutic tool in cases with massive bleeding and in neglected cases
Leveraging HPC Profiling & Tracing Tools to Understand the Performance of Particle-in-Cell Monte Carlo Simulations
Large-scale plasma simulations are critical for designing and developing
next-generation fusion energy devices and modeling industrial plasmas. BIT1 is
a massively parallel Particle-in-Cell code designed for specifically studying
plasma material interaction in fusion devices. Its most salient characteristic
is the inclusion of collision Monte Carlo models for different plasma species.
In this work, we characterize single node, multiple nodes, and I/O performances
of the BIT1 code in two realistic cases by using several HPC profilers, such as
perf, IPM, Extrae/Paraver, and Darshan tools. We find that the BIT1 sorting
function on-node performance is the main performance bottleneck. Strong scaling
tests show a parallel performance of 77% and 96% on 2,560 MPI ranks for the two
test cases. We demonstrate that communication, load imbalance and
self-synchronization are important factors impacting the performance of the
BIT1 on large-scale runs.Comment: Accepted by the Euro-Par 2023 workshops (TDLPP 2023), prepared in the

Hydrocephalus of King Charles II of Spain, the Bewitched King.
King of the Spanish Habsburg dynasty and sovereign of the overseas Spanish Empire, Charles II of Spain, was physically disabled, disfigured, mentally retarded, and he proved impotent. He is known in history as El Hechizado (the Bewitched) because both him and the people believed that his mental and physical incapacity were due to a "witchcraft act." Although several authors speculated about different diseases, most of them genetic such as pituitary hormone deficiency, distal renal tubular acidosis, Klinefelter syndrome, fragile X syndrome, or male XX hermaphroditism, the hypothesis of hydrocephalus was not taken into account. We don't have clear elements to hypothesize a certain etiology of Charles II' hydrocephalus; however, we think the herpetic infection he suffered of after his birth should not be ignored
Tritiation of amorphous and crystalline silicon using T <inf>2</inf> gas
Incorporation of tritium in hydrogenated amorphous silicon (a-Si:H) and crystalline silicon (c-Si) at 250 Ā°C using tritium (T 2) gas at pressures of up to 120 atm is reported. The tritium is stored in a surface layer which is approximately 150 and 10 nm for a-Si:H and c-Si, respectively. The concentration of tritium occluded in planar and textured c-Si is linearly dependent on the total surface area. The tritium is stable and the dominant tritium evolution occurs at temperatures above 300 Ā°C. The concentration of tritium locked in a-Si:H and c-Si was 20 and 4 at. %, respectively. Self-catalysis appears to be important in the tritiation process. Ā© 2006 American Institute of Physics
Extradural autologous temporal muscle graft mimicking a meningioma: Case report
Meningiomas are the most common dural tumour, but there are also many other dural masses which mimic their appearances, such as neoplastic and non-neoplastic lesions. In this paper we report another mass which may mimic a dural lesion, namely a muscle graft harvested from the temporal site and left in situ, used to achieve haemostasis in a posttraumatic temporal extradural hematoma in a young male patient. Solid knowledge of differentiating neuroimaging characteristics of dural masses, as well as its corroboration with the patientās medical history are extremely helpful in establishing an accurate diagnostic
Current management of abdominal stab wounds
Spitalul Clinic de UrgenČÄ āSfĆ¢ntul Pantelimonā, BucureČti, RomĆ¢nia, Al XI-lea Congres al AsociaČiei Chirurgilor āNicolae Anestiadiā din Republica Moldova Či cea de-a XXXIII-a Reuniune a Chirurgilor din Moldova āIacomi-RÄzeČuā 27-30 septembrie 2011CunoscĆ¢nd faptul cÄ atitudinea de management selectiv non-operativ a devenit un standard pentru plÄgile Ć®njunghiate, studiul nostru Či-a propus
validarea atitudinii diferenČiate faČÄ de plÄgile Ć®njunghiate ale abdomenului anterior. Materiale Či metodÄ: Studiul este descriptiv, retrospectiv, analiza
fiind centratÄ pe o experienČÄ de 11 ani (2000-2010) cuprinzĆ¢nd 64 cazuri de plÄgi abdominale anterioare. Media de vĆ¢rstÄ a lotului studiat a fost de
32 ani (17-65), lot alcÄtuit din 41 bÄrbaČi, 23 femei. Etiologia a fost la toate cazurile reprezentatÄ de agresiune fizicÄ cu armÄ albÄ. Rezultate: 48 cazuri
(75%) au fost supuse laparotomiei exploratorii immediate datoritÄ semnelor de iritaČie peritonealÄ, instabilitÄČii hemodinamice sau semnelor paraclinice
(hemogramÄ, biochimie, ecografie abdominalÄ, CT) ce sugerau leziuni de organ. 16 cazuri (25%) au fost monitorizate clinic Či imagistic, laparotomia
exploratorie fiind necesarÄ Ć®n 3 cazuri. Mortalitatea a fost nulÄ, morbiditatea de aproximativ 18% a inclus supuraČii parietale, 1 relaparotomie pentru
hemostazÄ suplimentarÄ Ć®ntr-o plagÄ hepaticÄ. Durata spitalizÄrii fost similarÄ la pacienČii operaČi Či la cei trataČi non- operativ. Concluzii: Studiul relevÄ
cÄ nu s-a Ć®nregistrat morbiditate majorÄ prin acest abord selectiv, pacienČii supuČi laparotomiei tardive fiind fÄrÄ risc vital. Aceste observaČii confirmÄ
concluziile din literaturÄ, Či anume faptul cÄ o perioadÄ de observaČie de 24 ore este adecvatÄ pentru aceastÄ patologie.Selective, non-operative management is now a standard for the management of abdominal stab wounds. Our study wishes to validate the differentiated
approach to stab wounds of the anterior abdomen. Materials and method: Our study is descriptive and retrospective, centering on an eleven year
experience (2000-2010), comprising of 64 abdominal stab wounds. The studied population was made up of 41 male and 23 female, with a median age of 32. All wounds were produced by stabbing. Results: 48 cases (75%) were subjected to immediate surgery because of the presence of peritonitic
signs, hemodynamic instability or explorations that suggested organ injury (CBC, biochemistry, abdominal ultrasound, computed tomography). 16
cases (25%) were monitored clinically and by imaging studies, exploratory laparotomy being needed in only 3 of these cases. We recorded no fatalities,
and overall morbidity was around 18% (surgical site infections, and one reintervention for supplementary hemostasis in a liver laceration). Duration
of hospital stay was constant. Conclusions: Our study shows that the selective approach did not lead to major morbidity, the patients subjected to late
laparotomy presenting no major or life threatening complications. Our observations confirm the recent consensus, stating that a 24 hour surveillance
period is adequate for this pathology

To be or not to be a neurovascular conflict: importance of the preoperative identification of the neurovascular conflict in the trigeminal neuralgia
The trigeminal neuralgia caused by neurovascular compression is a neurosurgical pathology requiring the preoperative identification as exact as possible of the neurovascular conflict. In this case, neuroimaging is very useful, as it allows not only the determination of the neurovascular conflict of the trigeminal nerve, but also the correct indication of an adequate surgical approach
The tumour volume influence on tumour recurrence and progression-free survival in the case of atypical meningiomas: Our experience on a series of 81 cases
Objective: The objective of our study was to evaluate a possible relation between the volume of atypical meningiomas (AMs) and the risk of tumour recurrence, as well as progression-free survival (PFS).
Material and methods: We evaluated 81 patients diagnosed with AMs (WHO grade II meningioma) who have undergone surgery at the "Prof. Dr. N. Oblu" Emergency Clinical Hospital Iasi between January 1, 2010, and December 31, 2019. The recorded data were demographic and imagistic (MRI, contrast-enhanced T1WI). We calculated the tumour volume prior to the surgery and evaluated the tumour recurrence using MRI at 12, 24, 36, 48 and 60 months after the surgery.
Results: 50.6% of patients had meningioma volume < 26.4 cm3. Women had larger tumour volumes than men (52.6%). Patients of age ? 60 years old, had tumour volumes ? 26.4 cm3 in 58.5% of cases and meningiomas with volumes ? 26.4 cm3 recurred earlier (p=0.010). Also, patients who had tumour volumes ? 26.4 cm3, had a shorter PFS (40.976 months), compared to patients with tumour volumes < 26.4 cm3, who had better PFS (53.4 months).
Conclusions: the tumour volume of AMs ? 26.4 cm3 represents a negative prognostic factor for both early tumour recurrence and reduced PFS
The employee as 'Dish of the Dayā:human resource management and the ethics of consumption
This article examines the ethical implications of the growing integration of consumption into the heart of the employment relationship. Human resource management (HRM) practices increasingly draw upon the values and practices of consumption, constructing employees as the āconsumersā of ācafeteria-styleā benefits and development opportunities. However, at the same time employees are expected to market themselves as items to be consumed on a corporate menu. In relation to this simultaneous position of consumer/consumed, the employee is expected to actively engage in the commodification of themselves, performing an appropriate organizational identity as a necessary part of being a successful employee. This article argues that the relationship between HRM and the simultaneously consuming/consumed employee affects the conditions of possibility for ethical relations within organizational life. It is argued that the underlying āethosā for the integration of consumption values into HRM practices encourages a self-reflecting, self-absorbed subject, drawing upon a narrow view of individualised autonomy and choice. Referring to Levinasā perspective that the primary ethical relation is that of responsibility and openness to the Other, it is concluded that these HRM practices affect the possibility for ethical being
