Current status of ceramic-based membranes for oxygen separation from air

Hashim SM, Mohamed AR, Bhatia S

Adv Colloid Interface Sci, 2010 Oct 15;160(1-2):88-100.
PMID: 20813344 DOI: 10.1016/j.cis.2010.07.007

There has been tremendous progress in membrane technology for gas separation, in particular oxygen separation from air in the last 20 years. It provides an alternative route to the existing conventional separation processes such as cryogenic distillation and pressure swing adsorption as well as cheaper production of oxygen with high purity. This review presents the recent advances of ceramic membranes for the separation of oxygen from air at high temperature. It covers the issues and problems with respect to the selectivity and separation performance. The paper also presents different approaches applied to overcome these challenges. The future directions of ceramic-based membranes for oxygen separation from air are also presented.
Fulltext Understanding the Turning Point of Patients with Diabetes

Hashim SM, Idris IB, Sharip S, Bahari R, Jahan N

Korean J Fam Med, 2021 Mar;42(2):123-131.
PMID: 32418396 DOI: 10.4082/kjfm.19.0177

BACKGROUND: The patient's intention to engage in diabetes care is the hallmark of role acceptance as a health manager and implies one's readiness to change. The study aimed to understand the process of having the intention to engage in diabetes care.
METHODS: A qualitative study using narrative inquiry was conducted at a public primary care clinic. Ten participants with type 2 diabetes of more than a 1-year duration were selected through purposive sampling. In-depth interviews were conducted using a semi-structured protocol guide and were audio-taped. The interviews were transcribed and the texts were analyzed using a thematic approach with the Atlas.ti ver. 8.0 software (Scientific Software Development GmbH, Berlin, Germany).
RESULTS: Three themes emerged from the analysis. The first theme, "Initial reactions toward diabetes," described the early impression of diabetes encompassing negative emotions, feeling of acceptance, a lack of concern, and low level of perceived efficacy. "Process of discovery" was the second overarching theme marking the journey of participants in finding the exact truth about diabetes and learning the consequences of ignoring their responsibility in diabetes care. The third theme, "Making the right decision," highlighted that fear initiated a decision-making process and together with goal-setting paved the way for participants to reach a turning point, moving toward engagement in their care.
CONCLUSION: Our findings indicated that fear could be a motivator for change, but a correct cognitive appraisal of diabetes and perceived efficacy of the treatment as well as one's ability are essentially the pre-requisites for patients to reach the stage of having the intention to engage.
Fulltext Exploring patients' reasons for participation in a medical education home visit program: a qualitative study in Malaysia

Tan CE, Jaffar A, Tohit N, Hamzah Z, Hashim SM

Perspect Med Educ, 2017 Jun;6(3):182-188.
PMID: 28386758 DOI: 10.1007/s40037-017-0353-1

INTRODUCTION: Direct contact with patients for medical education is essential in healthcare professional training. Patients who were recruited for a medical education home visit program in Malaysia did so on a voluntary basis without remuneration. This paper aims to explore their reasons for participation in this program.
METHODS: An exploratory qualitative study was conducted on patients who had been visited during the 2012/2013 academic session. Purposive sampling was done to select adult participants from varying ethnicities and ages from the list of patients. In-depth interviews were conducted at the participants' homes and were audio recorded. The transcripts of these interviews were analyzed using thematic analysis.
RESULTS: A total of nine in-depth interviews were conducted. Four main themes were identified from thematic analysis: 1) Perceived meaning of the visit; 2) Perceived benefits and risks; 3) Past healthcare experiences; 4) Availability for visits. The home visits meant different things to different participants, including a teaching-learning encounter, a social visit, a charitable deed or a healthcare check-up. The benefits and risks of accepting unknown students to their homes and sharing their health issues with them had been weighed prior to participation. Prior experience with healthcare services such as gratitude to healthcare providers or having a relative in the healthcare profession increased their receptivity for involvement. Lastly, enabling factors such as availability of time would determine their acceptance for home visits.
DISCUSSION: Patients agree to participate in medical education activities on a voluntary basis for various reasons. Providing good healthcare service and sufficient preparation are crucial to increase patient receptivity for such activities.
Bereavement in the elderly: the role of primary care

Hashim SM, Eng TC, Tohit N, Wahab S

Ment Health Fam Med, 2013 Sep;10(3):159-62.
PMID: 24427183

Bereavement in the elderly is a concern to primary care physicians (PCPs) as it can lead to psychological illness such as depression. Most people are able to come to terms with their grief without any intervention, but some people are not. This case highlights the importance of early recognition of bereavement-related depressive illness in elderly people. PCPs need to optimise support and available resources prior to, and throughout, the bereavement period in order to reduce the family members' burden and suffering.
Adolescent pregnancy outcomes and risk factors in Malaysia

Omar K, Hasim S, Muhammad NA, Jaffar A, Hashim SM, Siraj HH

Int J Gynaecol Obstet, 2010 Dec;111(3):220-3.
PMID: 20800837 DOI: 10.1016/j.ijgo.2010.06.023

OBJECTIVE: To assess the outcomes and risk factors of adolescent pregnancies in 2 major hospitals in Malaysia.
METHODS: We conducted a case-control study of pregnant girls aged 10 through 19 years. The controls were women aged 20 through 35 years who did not become pregnant in their adolescence. Cases and controls were matched for parity and place of delivery. Data were collected from questionnaires and the hospitals' medical records.
RESULTS: The study included 102 cases and 102 controls. There were significant associations between adolescent pregnancy and low education level, low socioeconomic status, being raised by a single parent, not engaging in extracurricular school activities, engaging in unsupervised activities with peers after school, and substance abuse (P<0.05 for all); being anemic, being unsure of the expected delivery date, and having few antenatal visits and a late delivery booking; and low Apgar scores and perinatal complications.
CONCLUSION: Adolescent pregnancies are high-risk pregnancies. Better sexual health strategies are required to address the associated complications.
Fulltext Factors influencing late consultation among patients with rectal bleeding in University Kebangsaan Malaysia Medical Centre

PMID: 21198288

BACKGROUND: Patients' delay in the presentation with rectal bleeding had been identified as a factor for late diagnosis of colorectal cancer. This study was conducted to determine the prevalence of delay in consulting a medical practitioner and identifying associated factors.

MATERIALS AND METHODS: A cross-sectional study of 80 patients with rectal bleeding, aged 40 and above, was conducted between December 2008 and June 2009 in the endoscopy unit, University Kebangsaan Malaysia Medical Centre. The self-administered questionnaire included data on sociodemographic, concern of rectal bleeding, whether patients sought initial advice, any self treatment prior to medical consultation and patients' opinion on causes of their own rectal bleeding.

RESULTS: The prevalence of delay in the presentation of rectal bleeding was 60%. Patients who were less worried (OR 9.6; 95% CI 3.3-27.5), who did not seek anyoneandapos;s advice (OR 11.8; 95% CI 3.8-36.8) and took some treatment before seeking medical consultation (OR 5.0; 95% CI 1.0-24.1) were significantly more likely to delay. Multiple logistic regression revealed that less worry of rectal bleeding and not seeking anyoneandapos;s advice were important predictors (p<0.05). The majority of patients attributed their bleeding to benign causes.

CONCLUSION: A high proportion of patients with rectal bleeding in the high risk group delayed in seeking medical advice. Public education needs to focus on interventions to reduce the delay in presenting and diagnosis of colorectal carcinoma.
