PARP1 promotes tumor proliferation in lenalidomide-resistant multiple myeloma via the downregulation of microRNA-192-5p-AKT signaling.

Background: Lenalidomide-based therapies are recommended as first-line treatment for multiple myeloma (MM) patients, regardless of the transplant eligibility. Resistance to lenalidomide is a clinical problem that urgently needs to be addressed. The expression of poly(ADP-ribose) polymerase 1 (PARP1) is abnormally high in a variety of tumor tissues including MM.

Diagnostic Performance of Clinical and Routine Laboratory Data in Acute Mesenteric Arterial Occlusion-An International Multicenter Study.

Background: There are no clinical or laboratory markers that can diagnose acute mesenteric ischemia (AMI) accurately. This study aimed to find differences in clinical and laboratory markers between arterial occlusive AMI and other acute abdominal diseases where AMI was initially suspected.

Methods: This was a post hoc study of an international prospective multicenter study where data on patients with suspected AMI were collected.

An MRI-Derived Formula for Estimating the Native Joint Line Position in the Presence of Distal Femoral Bone Loss.

Background  In the presence of distal femoral condyle bone loss, estimation and restoration of the joint line (JL) position can be guided by extraarticular bony landmarks with the aid of mathematical formulas that rely on the innate correlations between periarticular measurements. To prevent JL elevation, the formula should incorporate the thickness of distal femoral articular cartilage. The aim of this study was to derive a formula to estimate native JL position.

False-positive dengue non-structural protein 1 in pregnancy.

Dengue is a vector-borne infection, which contributes to significant morbidity and mortality in endemic areas. It manifests rapidly within 2 wk from febrile, critical to recovery phase. The point-of-care test (POCT) comprises the non-structural protein 1 (NS1) antigen, IgM and IgG, which aids rapid diagnosis, leading to timely treatment.

Endoscopic ultrasound with bronchoscope-guided transesophageal cryobiopsy: A case series with technical insights, key enablers, and review of literature.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an established technique for lung cancer staging and the diagnosis of mediastinal diseases. Recently, the paradigm of EBUS guided mediastinal sampling with conventional cytology has shifted over to histology specimens through the use of cryobiopsy. This case series explores the novel technique, key enablers, and potential advantages of endoscopic ultrasound with bronchoscope-guided transesophageal cryobiopsy (EUS-B-TEC).

Development and validation of the Newborn Clubfoot Screening Checklist to improve the detection of postnatal congenital talipes equinovarus among newborns by non-orthopaedic-trained healthcare workers in Sarawak General Hospital: A cross-sectional prospective study.

Introduction: Non-orthopaedic-trained healthcare professionals face challenges in identifying postnatal clubfoot deformities due to the lack of suitable assessment tools, resulting in misdiagnosis. Therefore, this study aimed to develop and validate the Neonatal Clubfoot Screening Checklist (NCSC) to assist non-orthopaedic-trained healthcare professionals in postnatal clubfoot assessment.

Methods: The NCSC development involved five phases: conceptual understanding of deformity components, creation of pictorial representations, tool structure design, content and face validation, pilot study and field study.

Enhancing Diagnosis: The Role of Point-of-Care Ultrasound in Early Detection of Pericardial Effusion in Post-Radioactive Iodine Hypothyroidism.

Pericardial effusion is a relatively common classical pericardial syndrome that poses a diagnostic challenge for clinicians. There are varying clinical presentations of pericardial effusion, ranging from asymptomatic incidental findings on chest X-ray (CXR) or point-of-care ultrasound (POCUS) to hemodynamic instability in cardiac tamponade. Pericardial effusion is a notable cardiac manifestation of severe and long-standing hypothyroidism.

Take C.A.R.E of patient safety: A call to action.

In a dynamic healthcare environment, patient safety is crucial. A "Conscious Actions Reduce Errors" (C.A.

A multicentre, retrospective study of epidemiology and outcome of aplastic anaemia among adult population in Sabah and Sarawak from year 2006 to 2017.

Introduction: Aplastic anaemia (AA) is a rare disorder of bone marrow failure, characterized by bone marrow hypocellularity with pancytopenia. The annual incidence rates of AA in Asia are observed to be two to three times higher than Europe and North America. Since the introduction of immunosuppressive therapy (IST) and of allogenic stem cell transplant (SCT), the outcome of severe AA has significantly improved.

The impact of body mass index on mortality in COPD: an updated dose-response meta-analysis.

Background And Objective: The obesity paradox is a well-established clinical conundrum in COPD patients. This study aimed to provide an updated analysis of the relationship between body mass index (BMI) and mortality in this population.

Methods: A systematic search was conducted through Embase, PubMed, and Web of Science.

Tuberculosis treatment interruption: a qualitative exploration of barriers, challenges, coping strategies and facilitators in Malaysia.

Tuberculosis (TB) treatment interruption undermines the effectiveness of TB medications and jeopardizes treatment outcomes. This study aimed to explore barriers, challenges, coping strategies and facilitators of TB treatment interruption to understand the treatment pathway in achieving successful outcomes. In-depth interviews were conducted at public health clinics in Sarawak, Malaysia, utilizing a phenomenological approach.

Total Knee Replacement as Treatment for Hemophilic Arthropathy: A Case Series.

Background and objectives Hemophilic arthropathy is a known complication of patients with hemophilia, with the knee as the commonest joint affected. Patients with this condition have severe pain and restricted joint mobility, affecting their activities of daily living. Total knee replacement can increase these patients' quality of life.

A Review of Surgical Outcomes of Management of Sinonasal Malignancies: A 8-Year of Clinical Experience (2013-2021) at the Tertiary Centre, Sarawak.

Sinonasal carcinoma, a rare and challenging malignancy, originating in the nasal cavity and paranasal sinuses, poses diagnostic and management complexities. This 8-year retrospective analysis at Sarawak General Hospital aims to elucidate demographic trends, histopathological entities, and management outcomes, shedding light on this multifaceted malignancy. Emphasizing the significance of accurate histopathological classification, the study explores the impact on prognostication and treatment strategies.

Ceruminous Adenoma: A Case Report and Review of Literature.

Ceruminous adenoma is a rare and benign tumor of the external auditory canal and present with a nonspecific symptom. Biopsy with histopathology examination is required to establish the diagnosis. Wide local excision of tumour shows favourable outcome with a low recurrence rate.

Dry Medical Thoracoscopy with Artificial Pneumothorax Induction Using Veress Needle.

Background: In the absence of, or minimal-volume pleural effusion, conventional medical thoracoscopy (MT) is often precluded by the risk of lung injury. Dry medical thoracoscopy (dry MT) aims to ameliorate these dangers by inducing an artificial pneumothorax via needle insufflation or blunt dissection. Veress needle is a device used by surgeons to induce pneumoperitoneum before laparoscopic surgeries, but is not commonly reported in dry MT.

Live Fish in the Throat Causing Upper Airway Obstruction and Esophageal Perforation.

Having a large live fish stuck in the throat is rare and prompts the urgent need to secure a definitive airway. Such sizeable foreign body (FB) in the aerodigestive tract also poses a constant threat of hollow viscus perforation, and the removal process can be complex. This report describes a fishing mishap causing the impaction of a large live fish in the laryngopharynx and esophagus, leading to respiratory distress and upper esophageal perforation.
