The current management of acute diverticulitis of the left colon (ADLC) requires tests with high prognostic value. This paper analyzes the usefulness of ultrasonography (US) in the initial diagnosis of ADLC and the validity of current classifications schemes for ADLC.
This retrospective observational study included patients with ADLC scheduled to undergo US or computed tomography (CT) following a clinical algorithm. According to the imaging findings, ADLC was classified as mild, locally complicated, or complicated. We analyzed the efficacy of US in the initial diagnosis and the reasons why CT was used as the first-line technique. We compared the findings with published classifications schemes for ADLC.
A total of 311 patients were diagnosed with acute diverticulitis; 183 had ADLC, classified at imaging as mild in 104, locally complicated in 60, and complicated in 19. The diagnosis was reached by US alone in 98 patients, by CT alone in 77, and by combined US and CT in 8. The main reasons for using CT as the first-line technique were the radiologist's lack of experience in abdominal US and the unavailability of a radiologists on call. Six patients diagnosed by US were reexamined by CT, but the classification changed in only three. None of the published classification schemes included all the imaging findings.
US should be the first-line imaging technique in patients with suspected ADLC. Various laboratory and imaging findings are useful in establishing the prognosis of ADLC. Sovleplenib New schemes to classify the severity of ADLC are necessary to ensure optimal clinical decision making.

Delayed graft function (DGF) is a frequent complication after kidney transplantation affecting long-term outcome.
A total of 525 consecutive recipients (age 54.2 ± 13.4 years, 33% female) of kidneys from deceased donors transplanted between 2005 and 2012 were retrospectively examined. DGF was defined as the need of dialysis within the first week after transplantation.
DGF developed in 21.1% (n= 111). Factors associated with DGF (P≤ .035, respectively) were recipient body mass index, C-reactive protein of the recipient, residual diuresis, cold ischemia time, donor age, and diuresis in the first hour after transplantation. Median duration of DGF was 16 (2-66) days. Patients after DGF had a significantly lower GFR compared with recipients without DGF either after 3 (32.9 ± 16.5 vs 46.3 ± 18.4 mL/min/1.73 m
) or after 12 months (38.9 ± 19.3 vs 48.6 ± 20.4 mL/min/1.73 m
, P< .001, resp.). During DGF, 12.4% developed BANFF II and 18.0% BANFF I rejection, 20.2% had signs of transplant glomerulitis (first biopsy), and 16.2% (n= 18) remained on dialysis.
DGF affects 1 out of 5 kidney transplants from deceased donors. Minimizing modifiable risk factors, in particular immunologic risk, may ameliorate the incidence and outcome of DGF. The outcome of DGF depends mainly on the diagnosis of any rejection and worsens upon detection of transplant glomerulitis and pronounced interstitial fibrosis and tubular atrophy (IFTA).

The aim of the present work was to assess the knowledge and attitudes of different health care workers and laypeople toward the donation and transplantation procedure.
A survey consisting of questions regarding brain death diagnosis, legal organization or organ donation, and the transplantation procedure were sent to participants 56 intensive care unit (ICU) doctors, 76 ICU nurses, 188 sixth-year medical students, and 320 general practitioners (GPs). Laypeople were also asked to complete the survey.
The majority of participants reported being aware of legal regulations for organ donation in Hungary (88.5%). Roughly 25% of GPs and 60% of laypeople were unaware of the opt-out system effective in the country. Less than one-third of ICU physicians (26.9%) and nurses (34.7%) were able to list the organs that may be transplanted from a deceased donor; GPs (22.4%) and medical students (20%) performed even worse on this item. The willingness of ICU specialists (57%) and ICU nurses (45%) to support donating their own organs was moderate.
The results of this survey indicate a need for graduate and postgraduate education and regular teaching programs regarding organ donation and transplantation. More active use of modern media is proposed to improve public awareness and acceptance of organ donation.

Several ANNs are trained to replicate an SDRE controller developed for a satellite attitude dynamics simulator (SADS) to display the technique's efficacy. The neural controllers have reduced computational complexity compared with the original SDRE controller, allowing its execution at a significantly higher rate. One of the neural controllers was validated using the SADS in a practical experiment. The experimental results indicate that the training error is sufficiently small for the neural controller to perform equivalently to the original SDRE controller.An issue regarding security synchronization is addressed for a class of interval type-2 (IT2) fuzzy stochastic multiplex complex networks with fuzzy hybrid control under deception attacks. Firstly, some complicated facts are considered in a unified network framework, such as multiplex, multiple delays, and stochastic disturbances, etc. In particular, different from the traditional hypothesis, the uncertainty is taken into consideration for the membership functions and along with the strategy of upper and lower bound and the correlative tradeoff functions to overcome this uncertainty. Secondly, malicious data are injected into channels between sensor and controller that may lead to undesired system performance. Then, based on Lyapunov stability theory and comparison principle, a novel IT2 fuzzy hybrid controller, containing a state feedback controller and a network-based impulsive controller, is designed to ensure a mean-square bounded synchronization so that the error states can converge below error thresholds. Finally, impulsive effects including both positive and negative roles are considered simultaneously in the security synchronization strategy, and the feasibility of the designed scenario is demonstrated by two numerical examples.For the safe working of rolling bearing, this paper presents a fault severity assessment method through optimized multi-dictionaries matching pursuit (OMMP) and Lempel-Ziv (LZ) complexity. To solve the redundancy problem of over-complete dictionary, the OMMP is proposed by introducing the quantum particle swarm optimization into matching pursuit for best representing the original vibration signal. And then, LZ complexity is calculated as an index of fault severity assessment by reconstructed signal. The performance of assessment method is verified through the measured signals of three bearing tests, and the comparisons with various methods are specifically described. The results indicate that the OMMP method averagely takes the shortest running time for the vibration signal decomposition. The assessment method is able to effectively evaluate different fault sizes of rolling bearing, and has a great applicability to in the condition-based maintenance of rotating machineries.
The aim of this study was to describe the potential advantages of the 3D endoscope-assisted anterior tonsillar fossa approach to elongated styloid process.
A 58years-old woman was reported to our Department with one-year history of odynophagia, latero-cervical pain on the left side, and ipsilateral foreign body sensation. Pain was dull and intermittent in nature. The patient had visited different clinics, she had a physiatric and maxillo-facial evaluation with two dental extraction without any relief of the symptoms. On physical examination a hard-bony consistency area was palpated over left-sided tonsillar fossa, evocating severe pain. Three-dimensional computed tomography (CT) confirmed an anomalous length of the left styloid process and a diagnosis of Eagle's syndrome (ES) was made. After careful surgical and anesthesiology evaluation, we decided to proceed with the partial excision of the styloid process with a 3d endoscope-assisted transoral anterior tonsillar fossa approach (Reddy et al., 2020).
Tgreat didactic tool. In our opinion is not necessary to remove all the styloid process, as other authors suggest (Lisan et al., 2019 [3]), but is sufficient a partial styloidectomy after cutting the stylohyoid ligament.
To present a technique of temporary uterine artery clamping before laparoscopic surgery for prevention of blood loss in cornual ectopic pregnancy.
Step-by-step explanation of the entire surgical procedure using video and still images (Canadian Task Force classification III).
Tertiary university-based hospital.
A 37-year-old woman who presented with amenorrhea of 55 days and extremely high β-hCG level of 281,400 mIU/mL. Transvaginal ultrasound examination revealed a 7 cm mass with ample blood supply invading the muscularis layer around the right uterine cornua.
Institutional Review Board and Ethics Committee approval was obtained. After pelvic adhesiolysis, retroperitoneum was dissected and the bilateral uterine arteries were exposed. To reduce the possibility of massive hemorrhage, titanium clips were used to temporarily block the bilateral uterine arteries. Laparoscopic inspection showed the mass as dark and blue, consistent with the diagnosis of cornual pregnancy. After removal of the cornual lesi blockage of the uterine artery during surgery could prevent heavy blood loss, especially in difficult surgeries such as myomectomy for complex uterus fibromas or adenomyomectomy. Moreover, this technique would be feasible for emergent cases, including conservative surgery for cesarean scar pregnancy, and could also replace traditional uterine artery embolization for treating cornual pregnancy.
To assess Indonesian dentists' knowledge of risk factors and diagnostic procedures related to oral cancer (OC) and to determine the factors that influenced their level of knowledge.
A modified version of a questionnaire that had been used to assess dentists' knowledge regarding OC in Canada was used. A total of 816 dentists were invited to participate in the study.
The total response rate was 49.2%; however, the number of dentists from 5 regions in Jakarta were equally represented. Use of tobacco or alcohol and history of previous OC were the top 3 risk factors that were answered correctly by dentists, but there was a high proportion of dentists who considered some without any evidence as risk factors. Almost half of the dentists did not know the early signs of OC and that erythroplakia and leukoplakia were associated with increased risks of developing OC. Only about 27% of dentists had a high level of knowledge of risk factors and fewer dentists demonstrated a good knowledge of diagnostic procedures. Dentists' age group, year of graduation, and experience of continuing education significantly influenced the level of knowledge of diagnostic procedures (P < .
