Abstract Two cats from separate households presented to a veterinary referral hospital with signs of fever, malaise and respiratory distress. Both cats underwent thoracic radiography, which revealed multilobar pulmonary nodular changes. To further characterise the pulmonary parenchymal disease, computed tomography was performed, and lung samples were obtained via fine needle aspirates in both cats, as well as an endotracheal wash in one cat. Cytology yielded mixed inflammation, while cultures identified the presence of Neisseria animaloris . Following antibiotic therapy, both cats demonstrated complete resolution of clinical signs, consistent with full recovery. Despite the potential for severe clinical illness and widespread pulmonary involvement marked by sepsis and respiratory compromise, pulmonary Neisseria infections in cats can be successfully treated with medical management. Due to their nodular pulmonary pattern, Neisseria infections may be mistaken for pulmonary neoplasia and can result in euthanasia if necessary diagnostics are not undertaken.

Background: Interventions supporting medical care and enhancing quality of life in neurodegenerative or age-related cognitive decline are strongly needed. Electroencephalographic (EEG) neurofeedback can enable users to modulate their brain activity through real-time feedback. However, evidence for its clinical effectiveness remains inconclusive, partly due to limited personalization and insufficient task relevance in existing protocols. Objective: We tested whether personalized EEG neurofeedback supervised by deep neural networks (DNNs) can enhance cognitive performance in older adults. Methods: Fifty-seven healthy adults aged 41 to 64 (31 women), including a sham-feedback control group, completed a personalized neurofeedback protocol with DNNs fine-tuned to individual EEG patterns. The procedure included pre- and post-training assessments using a transitive reasoning task, three diagnostic sessions to adapt the DNN to each participant, and 10 neurofeedback sessions based on a gamified delayed-match-to-sample paradigm. Results: The training group showed robust gains across all three variants of the reasoning task (each p < .01), whereas the sham group improved only on the easiest variant. Groups did not differ at pretest; however, at posttest the training group outperformed the sham group on all task conditions (each p < .03), showing also a larger neural effort (lower alpha band power) and increased beta and gamma band connectivity (higher phase lag index). Conclusion: Personalized, task-oriented neurofeedback guided by individually fine-tuned DNNs can produce cognitive enhancement after relatively few sessions. The proposed Task-Pretrained, Subject-Finetuned Neurofeedback (TPSF-NF) framework is scalable to other cognitive domains in future research.

Today, Legal issues plays an important role in the field of business management for dynamic environment. This paper explores the importance of legal aspect in the field of business management especially in small scale industries and its impact to resolve dispute mechanisms. The study also addresses the challenges in implementing law and practices in the business administration. Basically, study utilizes secondary data. Findings of the study explores the importance of positive legal risk management and how it helps in decision making process.

We describe a general solution to the problem of determining diagnostic accuracy without the use of a perfect reference standard and in the presence of interpreter variability. The accuracy of a diagnostic test is typically determined by comparing its outcomes with those of an established reference standard. But the accuracy of the standard itself and those of the interpreters strongly influence such assessments. We use our solution to examine the effects of the properties of the standard, the reliability of the interpreters, and the prevalence of abnormality on the measured sensitivity and specificity. Our results provide a method of systematically adjusting the measured sensitivity and specificity in order to estimate their true values. The results are validated by simulations and their detailed application to specific cases are described.

Although depression has been linked with both the irritable bowel syndrome and non-organic abdominal pain, which are common in gastrointestinal outpatients, the prevalence of depression in most surveys of outpatient practice has been low. Use of the Beck Depression Inventory to screen new referrals to a general medical and gastrointestinal clinic and to a minor surgical clinic showed that 50 of 100 medical patients were rated as having some degree of depression, compared with 14 of 75 (19%) of the surgical patients in whom abdominal pain and bowel dysfunction were rare (X2 = 9.6, p less than 0.01). In the medical clinic no organic disorder was detected in 64% of the depressed patients, the majority of whom presented with abdominal pain or irritable bowel syndrome. Depression was significantly commoner in this group of patients than in those with other conditions, (X2 = 6.63, p = 0.01). That depression is common in gastrointestinal outpatients is not always appreciated and its symptoms should be sought in all patients with bowel dysfunction and chronic abdominal pain.
