Besides offering a tribute to Hrayr Terzian, this article provides a brief historical overview of the different clinical pictures caused by bilateral temporal lesions from the first animal observations by Sanger Brown (1852-1928) and sir Edward Albert Sharpey-Schäfer (1850-1935), later confirmed and expanded upon by Heinrich Klüver (1897-1979) and Paul C. Bucy (1904-1992), to the first cases of bitemporal lesions in humans, including that of the famous patient H.M. (Henry Gustav Molaison, 1926-2008).
Previous studies have shown that Aβ-amyloid (Aβ) likely promotes tau to spread beyond the medial temporal lobe. However, the Aβ levels necessary for tau to spread in the neocortex is still unclear.

Four hundred sixty-six participants underwent tau imaging with [18F]MK6420 and Aβ imaging with [
F]NAV4694. Bavdegalutamide clinical trial Aβ scans were quantified on the Centiloid (CL) scale with a cut-off of 25 CL for abnormal levels of Aβ (A+). Tau scans were quantified in three regions of interest (ROI) (mesial temporal (Me); temporoparietal neocortex (Te); and rest of neocortex (R)) and four mesial temporal region (entorhinal cortex, amygdala, hippocampus, and parahippocampus). Regional tau thresholds were established as the 95%ile of the cognitively unimpaired A- subjects. Bavdegalutamide clinical trial The prevalence of abnormal tau levels (T+) along the Centiloid continuum was determined.

The plots of prevalence of T+ show earlier and greater increase along the Centiloid continuum in the medial temporal area compared to neocortex. Prevalence of T+ was low but associated with Aβ level between 10 and 40 CL reaching 23% in Me, 15% in Te, and 11% in R. Between 40 and 70 CL, the prevalence of T+ subjects per CL increased fourfold faster and at 70 CL was 64% in Me, 51% in Te, and 37% in R. In cognitively unimpaired, there were no T+ in R below 50 CL. link2 The highest prevalence of T+were found in the entorhinal cortex, reaching 40% at 40 CL and 80% at 60 CL.

Outside the entorhinal cortex, abnormal levels of cortical tau on PET are rarely found with Aβ below 40 CL. Above 40 CL prevalence of T+ accelerates in all areas. Moderate Aβ levels are required before abnormal neocortical tau becomes detectable.

Tendency is to moderate the injected activity and/or reduce acquisition time in PET examinations to minimize potential radiation hazards and increase patient comfort. This work aims to assess the performance of regular full-dose (FD) synthesis from fast/low-dose (LD) whole-body (WB) PET images using deep learning techniques.

Instead of using synthetic LD scans, two separate clinical WB
F-Fluorodeoxyglucose (
F-FDG) PET/CT studies of 100 patients were acquired one regular FD (~ 27 min) and one fast or LD (~ 3 min) consisting of 1/8
of the standard acquisition time. A modified cycle-consistent generative adversarial network (CycleGAN) and residual neural network (ResNET) models, denoted as CGAN and RNET, respectively, were implemented to predict FD PET images. The quality of the predicted PET images was assessed by two nuclear medicine physicians. Moreover, the diagnostic quality of the predicted PET images was evaluated using a pass/fail scheme for lesion detectability task. Quantitative analysis usinges present almost similar performance in terms of lesion detectability, qualitative scores, and quantification bias and variance.
Peptide-based prostate-specific membrane antigen (PSMA) targeted radionuclide therapy (TRT) agent [
Lu]-PSMA-617 has emerged as leading TRT candidate for treatment of castration-resistant prostate cancer (mCRPC). [
Lu]-PSMA-617 and other small molecule-based PSMA ligands have shown efficacy in reducing the tumor burden in mCRPC patients but irradiation to the salivary gland and kidneys is a concern and dose-limiting factor. Therefore, methods to reduce non-target organ toxicity are needed to safely treat patients and preserve their quality of life. Herein, we report that addition of cold PSMA ligand PSMA-11 can aid in reducing the uptake of [
Lu]-PSMA-617 in the salivary glands and kidneys.

Groups of athymic nude mice (n = 4) bearing PC3-PIP (PSMA+) tumor xenografts were administered with [
Lu]-PSMA-617 along with 0, 5, 100, 500, 1000, and 2000 pmoles of PSMA-11 and biodistribution studies were performed at 1 h.

Biodistribution studies at 1 h post-administration revealed that [
Lu]-PSMA-617 uptake in PC3-PIP tumors was 21.71 ± 6.13, 18.7 ± 2.03, 26.44 ± 2.94, 16.21 ± 3.5, 13.52 ± 3.68, and 12.03 ± 1.96 %ID/g when 0, 5, 100, 500, 1000, and 2000 pmoles of PSMA-11 were added, respectively. Bavdegalutamide clinical trial Corresponding uptake valuesin kidney were 123.14 ± 52.52, 132.31 ± 47.4, 84.29 ± 78.25, 2.12 ± 1.88, 1.16 ± 0.36, and 0.64 ± 0.23 %ID/g, respectively. Corresponding salivary gland uptake values were 0.48 ± 0.11, 0.45 ± 0.15, 0.38 ± 0.3, 0.08 ± 0.03, 0.09 ± 0.07, and 0.05 ± 0.02 % ID/g, respectively.

The uptake of [
Lu]-PSMA-617 in the salivary gland and kidney can be substantially reduced without significantly impacting tumor uptake by adding cold PSMA-11.

Indigenous populations have higher substance use than non-indigenous populations. Current evidence on indigenous substance use is largely derived from national household surveys, while there are no specifically designed, culturally specific methodological studies available to determine the prevalence of substance abuse among the indigenous tribes. The present study examined the prevalence and predictors of alcohol use, smoking, and betel quid chewing among indigenous tribes in South India.

We conducted a cross-sectional population-based random survey of 2186 tribal households in the Wayanad District, Kerala. A self-prepared, pilot-tested structured interview schedule was used to collect information on sociodemographic variables and substance use. Multivariate logistic regression models were used to examine the sociodemographic predictors of substance use.

The overall prevalence of current alcohol use, current smoking and daily betel quid use was 17.2%, 18.8% and 47.6% respectively. link2 Consistently, male gespecific de-addiction policies and programmes, alongside a consideration of the critical sociodemographic predictors.The emerging technique of microfluidics offers new approaches for precisely controlling fluidic conditions on a small scale, while simultaneously facilitating data collection in both high-throughput and quantitative manners. link3 As such, the so-called lab-on-a-chip (LOC) systems have the potential to revolutionize the field of biotechnology. But what needs to happen in order to truly integrate them into routine biotechnological applications? In this chapter, some of the most promising applications of microfluidic technology within the field of biotechnology are surveyed, and a few strategies for overcoming current challenges posed by microfluidic LOC systems are examined. In addition, we also discuss the intensifying trend (across all biotechnology fields) of using point-of-use applications which is being facilitated by new technological achievements.The primary aim of this study was to describe the use of primary anti-infective prophylaxis (AP) in common clinical practice in patients affected by immune thrombocytopenia (ITP) and treated with RTX. Population studied consisted of patients affected by ITP (age ≥ 18 years) who had received at least one dose of RTX from January 2008 to June 2018. Five Italian haematology centres participated in the current study. Data were retrospectively collected demographic data (age, gender), concomitant comorbidities and previous therapies for ITP, characteristics of AP, the occurrence of infections and their management. The ITP cohort consisted of 67 patients sub-grouped into two categories according to the administration of AP (1) treated with AP (N= 34; 51%) and (2) not treated with AP (N=33, 49%). link3 AP consisted of combined trimethoprim/sulfamethoxazole (TMP/SMX) and acyclovir (AC) in half of patients. TPM/SMX as a single agent was adopted in 32% patients and one patient received only AC. Overall, infections were experienced in 15% of patients during follow-up with a similar proportion in the 2 groups (treated and not treated) of patients (14.7% vs 15%). Clinical course of infections was however, less severe in patients treated with AP, where all infections were grade 2 and did not require hospitalization. In neither group of patients was reported Pneumocystis pneumonia. In conclusion, despite the absence of clear evidence, our analysis shows that AP in patients with ITP receiving RTX is frequently adopted, even if in the absence of well-defined criteria. Prophylaxis administration is quite consistent within the same haematological Center; thus, it seems related to clinicians' experience.The BCL2 inhibitor venetoclax is transforming the management of patients with chronic lymphocytic leukemia (CLL), given its high efficacy in relapsed/refractory CLL as observed in both early-phase and randomized clinical trials. The present study aimed to determine whether venetoclax is effective and well tolerated in patients with CLL or Richter's syndrome (RS) in a real-world setting and to highlight factors impacting survival. Data from a venetoclax French compassionate use program were collected for 67 patients (60 with CLL and 7 with RS). link2 Most patients presented adverse genetic features, such as TP53 disruption (74%) or complex karyotype (58%). Tumor lysis syndrome was observed in 14 (22%) patients, and 16 (24%) patients were hospitalized for grade III/IV infection. In the CLL cohort, ORR was 75 %, 1-year PFS was 61% (95% CI = 47-72%) and 1-year OS 70% (95% CI = 56-80%). No impact of TP53 disruption was noted while complex karyotype was identified as a predictor of both inferior PFS (HR = 3.46; 95% CI = 1-12; log-rank p = 0.03) and OS (HR = 3.2; 95% CI = 0.9-11.4, log-rank p = 0.047). Among the seven patients with RS, two achieved an objective response to venetoclax; however, the median OS was only 1.1 month. The well-balanced safety/efficacy profile of venetoclax is confirmed in this real-world setting. Complex karyotype should be evaluated as a predictive factor of survival for patients treated by venetoclax.There has been an increase in the use of acetylsalicylic acid (ASA, Aspirin®) among patients with stroke and heart disease as well as in aging populations as a means of primary prevention. link3 The potentially life-threatening consequences of a postoperative hemorrhagic complication after neurosurgical operative procedures are well known. In the present study, we evaluate the risk of continued ASA use as it relates to postoperative hemorrhage and cardiopulmonary complications in patients undergoing cerebral aneurysm surgery. We retrospectively analyzed 200 consecutive clipping procedures performed between 2008 and 2018. Two different statistical models were applied. The first model consisted of two groups (1) group with No ASA impact - patients who either did not use ASA at all as well as those who had stopped their use of the ASA medication in time (> = 7 days prior to operation); (2) group with ASA impact - all patients whose ASA use was not stopped in time. The second model consisted of three groups (1) No ASA use; (2) Stopped ASA use (> = 7 days prior to operation); (3) Continued ASA use (did not stop or did not stop in time, less then 7 days prior to operation).
