We compared the Essential Features section of the ICD-11 Clinical Descriptions and Diagnostic Guidelines (CDDG) with the DSM-5 criteria sets for 103 diagnostic entities that appear in both systems. We rated 20 disorders (19.4%) as having major differences, 42 disorders (40.8%) as having minor definitional differences, 10 disorders (9.7%) as having minor differences due to greater degree of specification in DSM-5, and 31 disorders (30.1%) as essentially identical. Detailed descriptions of the major differences and some of the most important minor differences, with their rationale and related evidence, are provided. The ICD and DSM are now closer than at any time since the ICD-8 and DSM-II. Differences are largely based on the differing priorities and uses of the two diagnostic systems and on differing interpretations of the evidence. Substantively divergent approaches allow for empirical comparisons of validity and utility and can contribute to advances in the field.
Malaria is an endemic infection in tropical circles. selleckchem It can be transmitted from mosquitoes bite, but exceptional cases have been attributed to multiorgan transplantation.
This is a 34-year-old woman who received a heart transplant for final-stage dilated cardiomyopathy. Over the hospitalization, she developed fever, cephalalgia, and tonic-clonic seizures with MRI findings compatible with posterior reversible encephalopathy. A thick blood smear revealed hemoparasitic forms of Plasmodium vivax. Afterward, malaria was also diagnosed in recipients of one kidney and liver of the same organ donor. First-line treatment with artesunate was prescribed for 3days and chloroquine with primaquine thereafter for 14days. The patient was discharged and returned to the emergency department 5days later, complaining of gastrointestinal symptoms and developed multiorgan failure that led to death.
We report a case of malaria transmission through heart transplantation. Despite adequate and supervised treatment, it can be related to a fatal outcome. Malaria screening in organ donors should be considered in regions where endemicity can lead to rare cases of transmission by transplantation.

Exploring the mechanisms of herbicide resistance in weeds is an important part of designing resistance management strategies and rationalizing herbicide use. Beckmannia syzigachne is one of the most important agricultural weeds in China. Long-term use of acetyl-CoA carboxylase (ACCase)-inhibiting herbicides has led to the evolution of herbicide resistance in B. syzigachne. ACCase-inhibiting herbicides comprise three chemical families aryloxyphenoxypropionates (APPs), cyclohexanediones (CHDs) and phenylpyraxoline (DENs).
Based on whole-plant dose-response experiments, a B. syzigachne population (BS-R) was confirmed to be 12- and 20-fold resistant to the APP herbicides quizalofop-P-ethyl and clodinafop-propargyl, and 2.2-, 2.8- and 2.8-fold resistant to fenoxaprop-P-ethyl, the CHD herbicide sethoxydim and the PPZ herbicide pinoxaden, respectively, compared with its susceptible counterpart (BS-S). Resistance to clodinafop-propargyl in the BS-R population could not be reversed by the known cytochrome P450 (CY, this study demonstrates that the Ile-2041-Val mutation in BS-R population confers resistance to certain ACCase-inhibiting APP, CHD and PPZ herbicides in B. syzigachne. © 2021 Society of Chemical Industry.
Decreased expression of HLA-DR on monocytes (mHLA-DR) is a reliable indicator of immunosuppression in patients with sepsis and is correlated with increased risk of secondary infection and mortality. A flow cytometry-based laboratory developed test for the measurement of mHLA-DR in whole blood was validated for clinical trial enrollment, which is considered medical decision-making, for patients with severe sepsis or septic shock.
The BD Quantibrite™ anti-HLA-DR/anti-monocyte reagent measures antibodies bound per cell of HLA-DR on CD14+ monocytes. The mHLA-DR assay was planned to support inclusion/exclusion of patients for a clinical trial and was validated according to New York State Department of Health (NYSDOH) requirements for a new non-malignant leukocyte immunophenotyping assay.
Normal, healthy donor and sepsis patient samples were stable up to 72 h post-collection in Cyto-Chex BCT phlebotomy tubes. Pre-determined acceptance criteria were met for precision parameters (average %CV ≤ 20%) and global laboratory-to-laboratory comparisons (average %Δ ≤ 20%). The approaches taken to evaluate and report accuracy, analytical specificity and sensitivity, reportable range, reference interval, and the proposed multi-level quality control were accepted by NYSDOH.
In this study, the validation strategy necessary when the intended use of assay results changes from exploratory to medical decision making (patient enrollment), which successfully resulted in regulatory approval, is described.

Studies of pattern separation in humans rely on mnemonic discrimination tasks, which have been shown to tax hippocampal-dependent pattern separation. Although previous neuroimaging research has focused on hippocampal processing, little is known about how other brain regions, known to be involved in recognition memory performance, are involved in mnemonic discrimination tasks. Conversely, neuroimaging studies of pattern separation with whole-brain coverage lack spatial resolution to localize activation to hippocampal subfields. In this study, 48 healthy young adult participants underwent whole-brain high-resolution functional MRI (fMRI) scanning while completing a mnemonic discrimination task. A priori region-of-interest analyses revealed activation patterns consistent with pattern separation in distinct hippocampal subregions, particularly in the subiculum. Connectivity analyses revealed a network of cortical regions consistent with the memory retrieval network where fMRI activation was correlated with hippocampal activation.
