MATERIALS AND METHODS: A prospective, observational crosssectional survey was conducted from 1st May 2022 to 31st December 2022 at the University of Malaya Medical Centre, Kuala Lumpur. This survey included all neurosurgical patients aged 18 and above requiring urgent and semiemergency surgery. The next of kin were interviewed using a standardised questionnaire to obtain their perspectives on the effectiveness of the current consenting process, as well as to explore potential alternative methods for obtaining consent. Data were analysed using IBM SPSS Statistics.

RESULTS: The survey had 103 responses. The analysis revealed that the most common semi-emergency surgical procedures were craniotomy (22 cases) and external ventricular drain insertion (18 cases), followed by burr hole and drainage (14 cases). The most common primary diagnosis that needed urgent intervention was acute hydrocephalus. Interestingly, more than half of the patients (58 cases, 56.3%) had to wait for over 30 minutes to obtain consent from their next of kin prior to surgery. The next of kin interviewed had an age range of 25 to 72 years. The relationships of the next of kin were children (33 subjects), spouses (26 subjects), siblings (25 subjects), and parents (16 subjects) of the patients. Additionally, 96.1% of the respondents owned a smartphone with a mobile internet data connection, and 85.4% had internet connectivity at home. The most preferred method of telecommunication for this exercise was via WhatsApp. An interesting finding was the association between the level of trust in medical professionals and the preferred consent method. It was discovered that individuals who preferred physical consent had lower trust in the hospital and doctors, while those who preferred remote consent had higher trust.

Methods: One hundred and eighty-eight healthy subjects aged between 18 and 50 years with varying oral hygiene status who gave consent to participate were included in this cross-sectional study. The subjects were recruited from primary oral health care of MAHSA University. Oral hygiene of all the participants was measured using Oral Hygiene Index-Simplified (OHI-S). Stimulated saliva collected using paraffin wax was analyzed for salivary statherin, aPRP, and calcium. The relationship between salivary statherin, aPRP, and calcium levels with OHI-S was assessed using Spearman's Rank correlation coefficient; the strength of relationship was assessed by multiple linear regression analysis.

DESIGN: Observational study.

SETTING: A single-centre study in which eligible patients were recruited from T2DM clinic. Following consent, patients completed a questionnaire and underwent physical examinations. Patients had blood drawn for laboratory investigations and had a transthoracic echocardiography.

PARTICIPANTS: A total of 305 patients who were not known to have CVD were recruited. Patients with deranged liver function tests and end stage renal failure were excluded.

MAIN OUTCOME MEASURES: Echocardiographic parameters such as left ventricular ejection fraction, left ventricular mass index (LVMI), left ventricular hypertrophy, left atrial enlargement and diastolic function were examined.

RESULTS: A total of 305 patients predominantly females (65%), with mean body mass index of 27.5 kg/m2 participated in this study. None of them had either a history or signs and symptoms of CVD. Seventy-seven percent of patients had a history of hypertension and 83% of this study population had T2DM for more than 10 years. Mean HbA1c of 8.3% was recorded. Almost all patients were taking metformin. Approximately, 40% of patients were on newer anti-T2DM agents such as sodium-glucose cotransporter-2 and dipeptidyl peptidase 4 inhibitors. Fifty-seven percent (n=174) of the study population had SBHF at the time of study: diastolic dysfunction, increased LVMI and increased left atrial volume index (LAVI) were noted in 51 patients (17%), 128 patients (42%) and 98 patients (32%), respectively. Thirty-seven patients (12%) had both increase LVMI and LAVI.
