Dopaminergic drug treatment remediates exaggerated cingulate prediction error responses in obsessive-compulsive disorder.

Rationale: Patients with obsessive-compulsive disorder (OCD) have been found to show exaggerated error responses and prediction error learning signals in a variety of EEG and fMRI tasks, with data converging on the anterior cingulate cortex as a key locus of dysfunction. Considerable evidence has linked prediction error processing to dopaminergic function.

Objective: In this study, we investigate potential dopaminergic dysfunction during reward processing in the context of OCD.

Low Breast Conserving Surgery (BCS) rates in public hospitals in Malaysia: The effect of stage and ethnicity.

Introduction: Breast-conserving surgery (BCS) with radiation therapy is the procedure of choice for early-stage breast cancer. Survival and locoregional recurrence is non-inferior to mastectomy, with superior cosmetic and psycho-social outcomes. Differing health systems have demonstrated a wide variation in the rate of BCS.

Ten-Year Average Full Follow-up and Evaluation of a Contoured Focal Resurface Prosthesis (HemiCAP) in Patients in the United Kingdom.

A significant number of patients are affected by localized articular damage that is appropriate neither for traditional arthroplasty nor for biological repair. A focal resurfacing system using a matched contoured articular prosthetic (HemiCAP) has been introduced for the treatment of such cases. Independent long-term results of these implants are limited.

Optimal management of postoperative parenchymal air leaks.

Air leaks are the most common complication after pulmonary resection. Enhanced recovery after surgery (ERAS) programs must be designed to manage parenchymal air leaks. ERAS programs should consider two components when creating protocols for air leaks: assessment and management.

Digital Air Leak Monitoring for Lung Resection Patients: A Randomized Controlled Clinical Trial.

Background: Digital chest drainage devices objectively measure airflow to guide chest tube management. There are contradictory results regarding their utility in reducing length of stay and chest tube duration. The objective of this study was to compare digital and analog devices in patients undergoing anatomic lung resection.

Management of adults with diabetes on the haemodialysis unit: summary of guidance from the Joint British Diabetes Societies and the Renal Association.

Diabetic nephropathy remains the principal cause of end-stage renal failure in the UK and its prevalence is set to increase. People with diabetes and end-stage renal failure on maintenance haemodialysis are highly vulnerable, with complex comorbidities, and are at high risk of adverse cardiovascular outcomes, the leading cause of mortality in this population. The management of people with diabetes receiving maintenance haemodialysis is shared between diabetes and renal specialist teams and the primary care team, with input from additional healthcare professionals providing foot care, dietary support and other aspects of multidisciplinary care.

Esomeprazole and aspirin in Barrett's oesophagus (AspECT): a randomised factorial trial.

Background: Oesophageal adenocarcinoma is the sixth most common cause of cancer death worldwide and Barrett's oesophagus is the biggest risk factor. We aimed to evaluate the efficacy of high-dose esomeprazole proton-pump inhibitor (PPI) and aspirin for improving outcomes in patients with Barrett's oesophagus.

Methods: The Aspirin and Esomeprazole Chemoprevention in Barrett's metaplasia Trial had a 2 × 2 factorial design and was done at 84 centres in the UK and one in Canada.

S093: pneumatic balloon dilation for palliation of recurrent symptoms of achalasia after esophagomyotomy.

Background: Achalasia is a chronic disease affecting the myenteric plexus of the esophagus and lower esophageal sphincter. Treatment is aimed at palliating symptoms to improve quality of life. Treatment options for symptom relapse after esophagomyotomy include botox injection, repeat myotomy, per-oral endoscopic myotomy, or pneumatic balloon dilation (PBD).

Prevalence, clinical correlates, and outcomes of anaemia in multi-ethnic Asian patients with heart failure with reduced ejection fraction.

Aims: Recent international heart failure (HF) guidelines recognize anaemia as an important comorbidity contributing to poor outcomes in HF, based on data mainly from Western populations. We sought to determine the prevalence, clinical correlates, and prognostic impact of anaemia in patients with HF with reduced ejection fraction across Asia.

Methods And Results: We prospectively studied 3886 Asian patients (60 ± 13 years, 21% women) with HF (ejection fraction ≤40%) from 11 regions in the Asian Sudden Cardiac Death in Heart Failure study.

Is perceived force an accurate method of regulating exercise load for the neck?

Objective: Patient perceived level of force is commonly used to regulate exercise load. This study determined the accuracy of perceived force as a method of regulating exercise load for the cervical flexors and extensors.

Methods: Thirty healthy individuals performed submaximal isometric cervical flexion and extension exercise at perceived intensities (25%, 50%, and 75%) of their maximal voluntary contraction (MVC) with no feedback in a neck dynamometer.

Multinational and multiethnic variations in health-related quality of life in patients with chronic heart failure.

Background: Assessing health-related quality of life (HRQoL) in patients with heart failure (HF) is an important goal of clinical care and HF research. We sought to investigate ethnic differences in perceived HRQoL and its association with mortality among patients with HF and left ventricular ejection fraction ≤35%, controlling for demographic characteristics and HF severity.

Methods And Results: We compared 5697 chronic HF patients of Indian (26%), white (23%), Chinese (17%), Japanese/Koreans (12%), black (12%), and Malay (10%) ethnicities from the HF-ACTION and ASIAN-HF multinational studies using the Kansas City Cardiomyopathy Questionnaire (KCCQ; range 0-100; higher scores reflect better health status).

Obsessive-compulsive disorder in the elderly: A report from the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS).

Introduction: Obsessive-compulsive disorder (OCD) is a highly disabling condition, with frequent early onset. Adult/adolescent OCD has been extensively investigated, but little is known about prevalence and clinical characterization of geriatric patients with OCD (G-OCD≥65years). The present study aimed to assess prevalence of G-OCD and associated socio-demographic and clinical correlates in a large international sample.

Development of a Canadian deceased donation education program for health professionals: a needs assessment survey.

Purpose: The purpose of this survey was to determine how Canadian healthcare professionals perceive their deficiencies and educational requirements related to organ and tissue donation.

Methods: We surveyed 641 intensive care unit (ICU) physicians, 1,349 ICU nurses, 1,561 emergency room (ER) physicians, and 1,873 ER nurses. The survey was distributed by the national organization for each profession (the Canadian Association of Emergency Physicians, the Canadian Association of Critical Care Nurses, and the National Emergency Nurses Association).

Achievements and Future Directions of the APFCB Mass Spectrometry Harmonisation Project on Serum Testosterone.

As an outcome of the 2010 Asian Pacific Conference for Chromatography and Mass Spectrometry in Hong Kong, a collaborative working group was formed to promote the harmonisation of mass spectrometry methods. The Mass Spectrometry Harmonisation Working Group resides under the combined auspices of the Asia-Pacific Federation for Clinical Biochemistry and Laboratory Medicine (APFCB) and the Australasian Association of Clinical Biochemists (AACB). A decision was made to initially focus attention on serum steroids due to the common interest of members in this area; with the first steroid to assess being testosterone.

Paradoxical insomnia in a patient taking zopiclone.

We present a case of a man aged 20 years who was diagnosed with a major depressive disorder and was started on escitalopram and zopiclone. The patient had a significant response to escitalopram except that he developed severe insomnia which dramatically resolved following discontinuation of zopiclone. The patient was recommenced on low dose of zopiclone and unfortunately redeveloped moderate insomnia.

Is "not just right experience" (NJRE) in obsessive-compulsive disorder part of an autistic phenotype?

Objective: Harm avoidance (HA) and "not just right experience" (NJRE) have been proposed to be 2 core motivational processes underlying obsessive-compulsive disorder (OCD). The objective of this study was to explore whether NJRE demarcates a neurodevelopmental OCD subgroup distinct from HA related to autistic traits and/or to a broader phenotype of cognitive rigidity and sensory processing difficulties associated with an earlier age of OCD onset.

Methods: A correlational design investigated whether NJRE and HA are distinct entities in OCD and explored their relationship to autism spectrum disorder (ASD) traits measured by the Autism Quotient (AQ), sensory processing, set-shifting, and age of OCD onset in an OCD sample (N=25).

Risk Factors for Severe Renal Disease in Bardet-Biedl Syndrome.

Bardet-Biedl syndrome is a rare autosomal recessive, multisystem disease characterized by retinal dystrophy, renal malformation, obesity, intellectual disability, polydactyly, and hypogonadism. Nineteen disease-causing genes () have been identified, of which mutations in are most common in North America and Europe. A hallmark of the disease, renal malformation is heterogeneous and is a cause of morbidity and mortality through the development of CKD.

Childhood, adolescent and adult age at onset and related clinical correlates in obsessive-compulsive disorder: a report from the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS).

Objective: Many studies suggest that age at onset (AAO) is an important factor for clinically differentiating patients with juvenile and adult onset of obsessive-compulsive disorder (OCD). The present international study aimed to assess the prevalence of different AAO groups and compare related socio-demographic and clinical features in a large sample of OCD patients.

Methods: A total of 431 OCD outpatients, participating in the ICOCS network, were first categorised in groups with childhood (≤12 years), adolescent (13-17 years) and adult-onset (≥18 years), then in pre-adult and adult onset (≥18 years) and their socio-demographic and clinical features compared.
