A cross-sectional descriptive study was conducted to assess the level of caring behaviour among clinical nurses in Southern China and explore its influencing factors. The study was carried out in the Sixth Affiliated Hospital, South China University of Technology, Guangdong, China, from December 2022 to February 2023. A total of 537 nurses participated, and the mean scores for caring behaviour, responsibility perception, and inclusive leadership were examined. The mean score for caring behaviour among clinical nurses was 125.25 ± 18.31. The mean responsibility perception score was 21.38 ± 3.36, while the mean inclusive leadership score was 38.04 ± 6.56. Notably, the inclusive leadership questionnaire and responsibility perception showed significant positive correlations with caring behaviour (p <0.01). Furthermore, regression analysis indicated that inclusive leadership and responsibility perception exerted significant influences on nurses' caring behaviour (p <0.01). These findings underscore the importance of creating an inclusive leadership environment that enhances nurses' sense of responsibility perception in order to promote and improve nursing caring behaviour.

Fenestrated and branched endovascular aortic aneurysm repair (f-EVAR, b-EVAR, respectively) are technically challenging procedures that have evolved over the last decade for complex aortic aneurysms. They are alternatives to surgical repair for suprarenal and juxtarenal aortic aneurysms. A Pubmed database was reviewed by searching keywords related to f-EVAR, b-EVAR, and juxta renal abdominal aortic aneurysm (AAA) from the last five years to see current indications, contemporary techniques, and results of these techniques for juxtarenal aneurysms. Over the years, f-EVAR and b-EVAR have improved, with high technical success (>95%) and mortality rates of 1-5% for pararenal and 5-10% for thoracoabdominal aortic aneurysms.

Objective: To establish the diagnostic utility of immunohistochemistry markers p16 along with MDM2 and CDK-4 in confirming the diagnosis of well-differentiated and de-differentiated liposarcoma while taking Fluorescent in situ Hybridisation (FISH) as a gold standard.

Study design: A cross-sectional study. Place and Duration of the Study: Department of Histopathology, Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from 30th January 2022 to 30th June 2023.

Methodology: A standard panel of three immunohistochemistry markers p16, MDM2, and CDK4 were applied to 36 cases of atypical lipomatous tumours, well-differentiated liposarcoma (WDLPS), and de-differentiated liposarcoma (DDLPS), on which the gold standard FISH was already performed. The sample size was calculated with the help of a WHO calculator taking prevalence 1-2% in Pakistani population. Qualitative variables such as gender and site of tumour were presented by calculating frequency and percentages and comparison of Immunohistochemistry results with FISH was done by using a 2x2 table.

Results: The sensitivity and specificity of this triple marker panel for detecting WDLPS/DDLPS were 43.47% and 15.38%, respectively. The sensitivity and specificity of CDK4 for detecting WDLPS / DDLPS were 82.6% and 15.4%, those of MDM2 were 73.9% and 61.5 %, and those of p16 were 60.9% and 53.8%, respectively.

Conclusion: Among all three markers, CDK4 was the most sensitive and MDM2 was the most specific marker for detecting WDLPS-DDLPS. It also showed that a combination of these three markers improves the diagnostic credibility of the immunohistochemistry in diagnosing DDLPS and WDLPS but FISH is the most reliable and confirmatory method.

Objective: To evaluate the early detection of vascular obstruction in microvascular flaps using a thermographic camera.

Study design: A cross-sectional study. Place and Duration of the Study: Department of Plastic Surgery, Jinnah Burn and Reconstructive Surgery Centre, Lahore, Pakistan, from July to December 2023.

Methodology: Microvascular flaps with cutaneous islands were monitored postoperatively with a thermographic camera in addition to conventional clinical methods. The decision to re-explore was based on conventional methods, and confirmation was achieved through intraoperative findings of vascular obstruction during re-exploration.

Results: Thirty-one patients who underwent microvascular surgery were monitored postoperatively with a thermographic camera. There were 20 (64.5%) anterolateral thigh flaps, 4 (12.9%) radial forearm flaps, 3 (9.7%) scapular-parascapular flaps, 1 (3.2%) medial plantar flap, 1 (3.2%) myocutaneous gracilis flap, 1 (3.2%) latissimus dorsi (LD) flap, and 1 (3.2%) chimeric adductor longus and gracilis flap. Three (9.7%) flaps developed postoperative vascular obstruction. The thermographic camera detected complications two to four hours earlier than conventional methods, with a statistically significant difference (p >0.109).

Conclusion: A thermographic camera is a valuable, non-invasive, and simple tool for monitoring microvascular flaps. It can detect complications several hours earlier and has the potential to be a practice-changing modality.

Objective: To compare oral pregabalin with oral sertraline for treatment of uraemic pruritus.

Study design: Randomised controlled trial. Place and Duration of the Study: Department of Nephrology, Pak Emirates Military Hospital Rawalpindi, Pakistan, from October 2023 to January 2024.

Methodology: Patients with end-stage renal disease having pruritus for at least 6 weeks were included. Exclusion criteria comprised other dermatological or systemic diseases associated with pruritus, mental health issues, thrice-a-week haemodialysis schedule, and use of other treatments for uraemic pruritus. They were randomised to receive either pregabalin 75mg daily or sertraline 50mg daily for six weeks using computer-generated sequences. The Urdu version of the 5-D Itch scale was used to document the severity of pruritus at the baseline and at the end of therapy. Side effects to the treatment were also monitored.

Results: There were 8 (16.67%) females and 40 (83.33%) males, with a mean age of 52.19 ± 12.19 years. The baseline 5-D Itch scale scores were equal in both groups. Mean improvement in 5-D Itch scale scores was 3.75 ± 1.26 and 2.08 ± 1.18 with pregabalin and sertraline, respectively (p <0.001). Side effects were reported by 2 (8.33%) patients on pregabalin and none using sertraline (p = 0.489).

Conclusion: Pregabalin was found to be more effective than sertraline in treating uraemic pruritus, though with a statistically insignificant trend towards a higher frequency of side effects.

Objective: To determine the role of dexmedetomidine in potentiating the local anaesthetic efficacy of a low dose of bupivacaine when used as an adjuvant.

Study design: A prospective, double-blind, randomised study. Place and Duration of the Study: Department of Anaesthesia, Sindh Institute of Urology and Transplantation, Karachi, Pakistan, from July 2021 to February 2022.

Methodology: One hundred and eight patients of ASA physical class I-III undergoing transurethral resection of the prostate (TURP) under sub-arachnoid block (SAB) were enroled and distributed into two equal groups. Group BUPIPURE (BP) was given 7.5 mg of pure 0.5% hyperbaric bupivacain whereas group BUPIDEX (BD) was given 6 mg of 0.5% hyperbaric bupivacain with 3 μg dexmedetomidine intrathecally. The effects in Both groups were compared using chi-square and unpaired t-tests. A significance level of p <0.05 was used to evaluate the statistical significance.

Results: Both groups demonstrated a steady decrease in mean heart rate (mean HR 98.9-62.7 per minute as compared to 79.1-59.4 per minute in groups BP and BD, respectively), however, no patient reached to HR <50/min. Group BP had a higher HR variability than group BD. The two groups' median peak sensory levels were similar. However, a statistically significant difference was revealed in the time taken for 2-segment regression (87.5 ± 11.3 min vs. 115.5 ± 6.2 min p <0.001 in BP and BD), as well as the time to reach T10 sensory level (13.56 ± 2.5 min vs. 10.9 ± 3.0 min p <0.001).

Conclusion: In patients having TURP, intrathecal dexmedetomidine combined with low-dose bupivacaine results in a quicker start, extended sensory and motor block, and a decreased need for rescue analgesics.

Objective: To evaluate the efficacy and prognostic significance of reperfusion therapy in patients with Trousseau syndrome-related cerebral infarction.

Study design: Descriptive study. Place and Duration of the Study: Department of Neurology, Zhongshan Hospital of Xiamen University, School of Medicine, Xiamen University, Xiamen, China, and The Second Affiliated Hospital of Xiamen Medical College, Xiamen, China, between January 2017 and December 2023.

Methodology: Patients with Trousseau-associated cerebral infarction who were treated at two hospitals were included in the study. Clinical outcomes, including early neurological deterioration, intracranial haemorrhage, in-hospital mortality, 90-day modified Rankin scale (mRS) score, 90-day mortality, initial and discharge National Institutes of Health Stroke Scale (NIHSS) score, and ΔNIHSS (difference between the initial and discharge NIHSS score), were compared between the reperfusion-treated group (n = 9) and the conventionally treated group (n = 23).

Results: Patients who received reperfusion therapy demonstrated significant neurological improvement at discharge, with a statistically significant difference in their ΔNIHSS scores compared to those of the conventionally treated group (p <0.001). No significant differences were observed in early neurological deterioration (11.10% vs. 13.00%, p = 1.000), intracranial haemorrhage (33.33% vs. 8.70%, p = 0.121), in-hospital mortality (22.20% vs. 26.10%, p = 1.000), 90-day mortality (55.60% vs. 87.00%, p = 0.076), or 90-day mRS score (p = 0.052) between the two groups.

Conclusion: Despite the high mortality rate within 90 days, reperfusion therapy has the potential to improve the quality of life of surviving cancer patients with Trousseau-associated cerebral infarction.
