Utility of hand-held ultrasound for image acquisition and interpretation by trained Kenyan providers
ConclusionAmong POCUS trainees in rural Kenya, the hand-held ultrasound was found to be non-inferior to the traditional notebook ultrasound for focused obstetric image quality, focused obstetric image interpretation, and E-FAST image interpretation. However, hand-held ultrasound use was found to be inferior for E-FAST image quality. These differences were not observed when evaluating each E-FAST and focused obstetric views separately. The hand-held ultrasound allowed for rapid image transmission for remote review. (Source: Critical Ultrasound Journal)

Monitoring of pulmonary involvement in critically ill COVID-19 patients - should lung ultrasound be preferred over CT?
ConclusionsLUSS correlated with CTSS throughout ICU admission but performed similar or better at agreement between raters and mortality prognostication. Given the benefits of LUS over CT, it should be preferred as initial monitoring tool. (Source: Critical Ultrasound Journal)

Alveolar capillary dysplasia with misalignment of pulmonary veins in a premature newborn: the role of lung ultrasound
ConclusionLU could provide essential information to help diagnose and follow-up the underlying cause of persistent pulmonary hypertension of the newborn in an earlier and more effective way than chest X-ray. LU is suitable for routine monitoring of lung disease in the NICU. (Source: Critical Ultrasound Journal)

Accuracy of linear-probe ultrasonography in diagnosis of infraorbital rim fractures
ConclusionLinear probe ultrasonography is a good diagnostic tool and has better reliability than the plain film X-ray and can be used as alternative to CT in inferior orbital rim fracture. (Source: Critical Ultrasound Journal)

Feasibility of tele-guided patient-administered lung ultrasound in heart failure
ConclusionsIn this feasibility study, patients were able to produce interpretable lung ultrasound exams in more than 90% of remotely supervised sessions in their home environment. Larger studies are needed to determine whether remotely guided lung ultrasound could be useful to detect heart failure decompensation early in the home environment.

“Sponge pattern” of the spleen: a rarely described high-frequency ultrasound pattern in HIV-positive patients
We describe a reticulo-nodular “sponge pattern” in the spleen of an HIV-positive patient with Hodgkin’s lymphoma. Disseminated throughout the spleen, very small (1.5–2.0 mm) hypoechoic lesions having a branching reticulo-nodular distribution were seen. The lesions partly, but not entirely, follow splenic vasculature. Rev iew of stored images of other patients identified 15 more cases showing a similar pattern. All patients were HIV positive, almost all with CD4 counts below 200 cells/mm3. Seven (44%) were additionally diagnosed with HHV-8-associated diseases, but the pattern was seen with various underlying oppor...

Ultrasonographic measurement of the optic nerve sheath diameter to detect intracranial hypertension: an observational study
ConclusionsIn sedated neurocritical patients, with structural Acute Brain Injury, the ONSD measurement correlates with the invasive measurement of ICP. It was observed that with ONSD values less than 5.7 mm, the probability of being in the presence of ICP above 20 mmHg is very low, while for ONSD values greater than 5.7 mm, said probability clearly increases.

Lung ultrasound to evaluate aeration changes in response to recruitment maneuver and prone positioning in intubated patients with COVID-19 pneumonia: preliminary study
ConclusionsIn our investigation, recruitment maneuver and prone positioning demonstrated an enhancement in lung aeration when compared to supine position, as assessed by bedside lung ultrasound.Trial registration:www.clinicaltrials.gov, Number NCT05209477, prospectively registered and released on 01/26/2022.

Left atrial strain is associated with distinct inflammatory and immune profile in patients with COVID-19 pneumonia
DiscussionOur study shows that LA-S may be a more sensitive marker for diastolic dysfunction in severe COVID-19, which could identify patients at risk for a protracted inflammatory state. A differential immune trait in DYS patients at ICU admission, with persistent lymphopenia, enriched CM T-cells, and higher IL-6 may suggest distinct inflammatory states or migration patterns in patients that develop cardiac injury.

Measuring the accuracy of cardiac output using POCUS: the introduction of artificial intelligence into routine care
ConclusionsOur study demonstrates that novel automation-assisted VTI is feasible and can decrease variability while increasing precision in CO measurement. These results support the use of artificial intelligence-augmented image acquisition in routine critical care ultrasound and may have a role for evaluating the response of CO to hemodynamic interventions. Further investigations into artificial intelligence-assisted ultrasound systems in clinical settings are warranted. (Source: Critical Ultrasound Journal)

Optic nerve sheath diameter at high altitude: standardized measures in healthy volunteers
ConclusionsThe median ONSD and ONSD/ETD ratio in the city of Bogot á are similar to those described in other populations; however, approximately 10.8% of the healthy population may present higher values, which would limit the use of ONSD on its own for clinical decision-making, only repeated measurements with significant changes in the ONSD and ONSD/ETD or asymmet ries between the measurements of both eyes linked to clinical findings would allow the diagnosis of hICP.

Interpleural location of chest drain on ultrasound excludes pneumothorax and associates with a low degree of chest drain foreshortening on the antero-posterior chest X-ray
ConclusionAbsence of a CD on CUS post drainage, low CDI on CR and continuous air leak significantly associate with residual occult pneumothorax which may evade diagnosis on an antero-posterior CR. (Source: Critical Ultrasound Journal)
