Elevated peripheral blood monocyte count is associated with prolonged postoperative hospitalization and functional decline in patients with interstitial lung diseases undergoing surgical lung biopsy.

OBJECTIVE: Monocyte count and red cell distribution width (RDW) have shown prognostic potential in patients with fibrotic lung diseases. Their kinetics and prognostic usefulness of peripheral blood indices in patients with interstitial lung diseases (ILDs) undergoing surgical lung biopsy for diagnostic reasons have not been studied. PATIENTS AND METHODS: We retrospectively included consecutive patients with ILD who underwent surgical lung biopsy for diagnostic purposes Between 07/11/2019 and 11/10/2022. RESULTS: Fifty-five (n=55) patients were included in the study. Median age was 65.0 years (95% CI: 63.0 to 66.0). Postoperative peripheral blood monocyte count on Day 1 was significantly higher compared to preoperative, perioperative, and postoperative values on Day 90 (repeated measures ANOVA, p<0.0001). Patients in the high postoperative monocyte count group had significantly increased length of postoperative hospital stay [Mann-Whitney test, p=0.007] and significantly lower Forced Vital Capacity (FVC)% predicted 3 months after surgery [Mann-Whitney test, p=0.029] compared to patients in the low postoperative monocyte count group. Postoperative RDW on Day 90 was significantly higher compared to preoperative, perioperative and postoperative-Day 1 RDW (repeated measures ANOVA, p=0.008, p=0.006, p<0.0001, respectively). Patients in the high postoperative RDW group did not have increased hospital stay (Mann-Whitney test, p=0.49) or decreased FVC% predicted at 3 months compared to patients in the low postoperative RDW group (Mann-Whitney test, p=0.91). CONCLUSIONS: Peripheral blood monocyte count could be a prognostic biomarker for patients with ILDs undergoing diagnostic surgical lung biopsies. RDW does not seem to represent an acute phase biomarker but seems to increase over time following disease progression. Larger studies are urgently required.

Contrasting patterns of deficits in visuospatial memory and executive function in patients with major depression with and without ECT referral.

BACKGROUND: The pretreatment neuropsychological profile of drug-resistant patients with major depressive disorder (MDD) referred for electroconvulsive therapy (ECT) may differ from that of their drug-respondent MDD counterparts. Such differences could help in identifying distinct MDD subtypes, thus offering insights into the neuropathology underlying differential treatment responses. METHOD: Depressed patients with ECT referral (ECTs), depressed patients with no ECT referral (NECTs) and non-psychiatric Controls (matched groups, n=15) were assessed with memory and executive function tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB). RESULTS: ECTs scored significantly lower than NECTs in the Mini-Mental State Examination (MMSE; p=0.01). NECTs performed worse than Controls in the Paired Associates Learning (PAL) task (p<0.03; Control/NECT p<0.01) and the Spatial Recognition Memory (SRM) task (p<0.05; Controls/NECTs p<0.05); ECTs performed between Controls and NECTs, not differing from either. In the Intra/Extradimensional (IED) set-shifting task, ECTs performed worse that Controls and NECTS (IED: p<0.01; Controls/ECTs p<0.01), particularly in the shift phases, which suggests reduced attentional flexibility. In Stockings of Cambridge (SOC), ECTs abandoned the test early more often than Controls and NECTs (H=11, p<0.01) but ECTs who completed SOC performed comparably to the other two groups. CONCLUSIONS: A double dissociation emerged from the comparison of cognitive profiles of ECT and NECT patients. ECTs showed executive deficits, particularly in attentional flexibility, but mild deficits in tests of visuospatial memory. NECTs presented the opposite pattern. This suggests predominantly frontostriatal involvement in ECT versus temporal involvement in NECT depressives.

Current evaluation of the dysphagic patient.

Dysphagia is a symptom so common and diverse that is often considered as a disease in its own right. Its severity can range from a trivial problem to a lethal condition. It can seriously compromise the quality of life of affected patients, therefore management should be prompt. The implications of dysphagia in healthcare costs are immense. Assessment of dysphagic patients is based on a comprehensive history and thorough examination. In the present review we discuss physiology, aetiology, diagnosis and management emphasizing the role of a multidisciplinary team approach. We also focus on the role of fibreoptic endoscopic evaluation of swallowing which revolutionized over recent years the assessment of the dysphagic patient.
