Th aim of this study is to explore the diagnostic accuracy of smartphone-based D-EYE ophthalmoscopy in the diagnosis of optic nerve head (ONH) abnormalities and screening for glaucoma.

This is a prospective clinical-based validation study performed on 90 patients recruited from a tertiary teaching hospital. Patients underwent dilated fundus examination by slit-lamp and smartphone-based D-EYE fundoscopy operated by two experienced ophthalmologists.

The diagnostic accuracy of smartphone-based D-EYE ophthalmoscopy of normal vertical cup-to-disc ratio (VCDR) was acceptable (sensitivity 85.8%-96.4%; specificity 51.4%-96.4%). The D-EYE would often underestimate VCDR values as mean VCDR was significantly lower among overall and glaucoma cohorts (all p-value <0.001) for D-EYE in comparison with slit-lamp. In terms of ONH abnormalities, the D-EYE adequately demonstrated high sensitivity in the identification of only margins-related abnormalities (sensitivity 92.5%-96.6%). Overall, the diagnostic accuracy and agreement between expert ophthalmologists using the D-EYE and the reference slit-lamp examination were significantly poor.

We demonstrated that the D-EYE is a highly specific tool for VCDR within the normal range but not in patients with glaucoma. Despite being an easy and portable tool to measure VCDR, it is limited in terms of diagnosing ONH and blood vessel abnormalities.

The main objective of this study was to determine the sensitivity of abdominal ultrasonography (US) in patients with isoattenuating pancreatic carcinoma and to compare the frequency of secondary signs on abdominal US and endoscopic ultrasonography (EUS) in these tumours.

Twenty-four patients with histologically or cytologically verified isoattenuating pancreatic carcinoma who underwent abdominal US, contrast-enhanced CT and EUS of the pancreas as part of the diagnostic workup were included in this retrospective study. The sensitivity of abdominal US in detecting the isoattenuating pancreatic carcinoma was investigated and the frequency of secondary signs of isoattenuating pancreatic carcinoma on abdominal US and EUS was compared.

In 5 of 24 patients (21%) with isoattenuating pancreatic carcinoma, a hypoechogenic pancreatic lesion was directly visualised on abdominal US. Secondary signs were present on US in 21 patients (88%). These included dilatation of the common bile duct and/or intrahepatic bile ducts in 19/24 (79%), dilatation of the pancreatic duct in 3/24 (13%), abnormal contour/inhomogeneity of the pancreas in 1/24 (4%), and atrophy of the distal parenchyma in 1/24 (4%). Pancreatic duct dilatation was observed more frequently on EUS than on abdominal US (P=0.002). For other secondary signs, there was no significant difference in their detection on abdominal US and EUS (P=0.61-1.00).

Abdominal US is capable of detecting secondary signs of isoattenuating pancreatic carcinoma with high sensitivity and has the potential to directly visualise these tumours.

Anti-cancer medicine shortages are advancing challenges for patients and hospitals. This study aims to evaluate anti-cancer and supportive medicine shortages in a tertiary hospital in Pakistan and propose solutions.

A retrospective observational research was performed in a tertiary care hospital in Pakistan from 2016 to 2020. Data was retrieved from the hospital database using a questionnaire regarding short medicines' generic name, brand, dosage, source, total source, frequency, causes, impact, management, and analyzed by Microsoft Excel 2013.

Between January 2016 and December 2020, 43 individual medicine shortages were observed, with an average of 8.6 shortages per year. There were shortages of 22 medicines, including 8 anti-cancer (36.4%) and 14 supportive agents (63.6%). Total shortage days were 27,100, with an average of 1232 days (SD 757) per medicine. Supportive medicines' shortages were frequent, but oncology agents' shortages were constant. The most affected dosage form was injection. Cardiovas very few sources of supply, so it imports these drugs on a need basis to manage the shortages. But it is still concerning because of the huge financial burden on patients and institutions due to expensive import, and therapy become delayed as the import process takes time. Moreover, the most affected drug class was alkylating agents, and dosage was both injectable and oral medicines.
To assess the performance of the 'separation sign' as a predictor of normal placental separation in a large cohort of women at risk for placenta accreta spectrum (PAS) and in a high-risk subgroup with placenta previa or anterior low-lying placenta and at least one previous Cesarean delivery.

This was a prospective study of women at risk for PAS referred to a specialist clinic at between 22 and 38 weeks' gestation. All women underwent ultrasound assessment for the presence of the separation sign, which detects the difference in elasticity between the myometrium and the placenta, characterized by different rates of rebound after an ultrasound probe is used to apply pressure over the uteroplacental interface. When the sign is positive, the placenta appears to move relative to the myometrium, leading to the appearance or enhancement of the clear zone. The predictive performance of the separation sign for normal spontaneous placental separation at delivery was assessed.

Of the 194 included women, 163 had a pstetrics and Gynecology.
The separation sign could be a useful tool in women considered to be at risk for PAS, as it can facilitate the prediction of normal placental separation at delivery. This may prevent overtreatment, the associated iatrogenic morbidity and unnecessary allocation of clinical resources. © 2022 The Authors.

Ankle fracture displacement is an important outcome in clinical research examining the effectiveness of surgical and rehabilitation interventions. However, the assessment of displacement remains subjective without well-described or validated measurement methods. The aim of this study was to assess inter- and intrarater reliability of ankle fracture displacement radiographic measures and select measurement thresholds that differentiate displaced and acceptably reduced fractures.

Eight fellowship-trained orthopaedic surgeons evaluated a set of 26 postoperative ankle fracture radiographs on 2 occasions. Surgeons followed standardized instructions for making 5 measurements coronal displacement (3) talar tilt (1), and sagittal displacement (1). Inter- and intraobserver interclass correlations were determined by random effects regression models. Logistic regression was used to determine the optimal sensitivity and specificity for the measurements with the highest correlation.

Three of the 5 measures had excely reduced fractures. These measurement criteria can be used for the design and conduct of clinical research studying the impact of surgical treatment and rehabilitation interventions.
Current clinical classifications of olfactory function are based primarily upon a percentage of correct answers in olfactory identification testing. This simple classification provides little insight into etiologies of olfactory loss, associated comorbidities, or impact on the quality of life (QOL).

Community-based subjects underwent olfactory psychophysical testing using Sniffin Sticks to measure threshold (T), discrimination (D), and identification (I). The cognitive screening was performed using Mini-Mental Status Examination (MMSE). Unsupervised clustering was performed based upon T, D, I, and MMSE. Post hoc differences in demographics, comorbidities, and QOL measures were assessed.

Clustering of 219 subjects, mean age 51 years (range 20-93 years) resulted in 4 unique clusters. Tenalisib concentration Cluster 1 was the largest and predominantly younger normosmics. Cluster 2 had the worst olfaction with impairment in nearly all aspects of olfaction and decreased MMSE scores. This cluster had higher rates of smoking, heart disease, and cancer and had the worst olfactory-specific QOL. Cluster 3 had normal MMSE with relative preservation of D and I, but severely impaired T. This cluster had higher rates of smoking and heart disease with moderately impaired QOL. Cluster 4 was notable for the worst MMSE scores, but general preservation of D and I with moderate loss of T. This cluster had higher rates of Black subjects, diabetes, and viral/traumatic olfactory loss.

Unsupervised clustering based upon detailed olfactory testing and cognitive testing results in clinical phenotypes with unique risk factors and QOL impacts. These clusters may provide additional information regarding etiologies and subsequent therapies to treat olfactory loss.

Evolocumab has more potent lipid-lowering properties than statins. Aims The aims of this study were to investigate whether evolocumab pretreatment on top of statin therapy could prevent periprocedural microvascular dysfunction. Methods This study included 100 patients with stable coronary artery disease who were scheduled to undergo PCI and had high low-density lipoprotein cholesterol (LDL-C) under statin therapy. Patients were randomised to receive evolocumab 140 mg every 2 weeks for 2 to 6 weeks before PCI (evolocumab group N=54) or not (control group N=46). The primary endpoint was the index of microvascular resistance (IMR) after PCI. Troponin T was measured before and 24 hours after PCI. Results Geometric mean LDL-C was 94.1 (95% confidence interval [CI] 86.8-102.1) mg/dl and 89.4 (95% CI 83.5-95.7) mg/dl at baseline, and 25.6 (95% CI 21.9-30.0) mg/dl and 79.8 (95% CI 73.9-86.3) mg/dl before PCI, in the evolocumab group and in the control group, respectively. PCI was performed 22.1±8.5 days after allocation. Geometric mean IMR was 20.6 (95% CI 17.2-24.6) in the evolocumab group and 20.6 (95% CI 17.0-25.0) in the control group (p=0.98). There was no significant difference in the geometric mean of post-PCI troponin T (0.054, 95% CI 0.041-0.071 ng/ml vs 0.054, 95% CI 0.038-0.077 ng/ml; p=0.99) and in the incidence of major periprocedural myocardial infarction between the 2 groups (44.4% vs 44.2%; p=1.00). Conclusions Evolocumab pretreatment did not prevent periprocedural microvascular dysfunction in patients on modern medical management with statins.
