Fulltext A meta-analysis on immune checkpoint inhibitor efficacy for advanced non-small cell lung cancer between East Asians versus non-East Asians

Peng S, Ying AF, Tai BC, Soo RA

Transl Lung Cancer Res, 2020 Aug;9(4):1124-1137.
PMID: 32953491 DOI: 10.21037/tlcr-20-246

Background: We conducted a meta-analysis to assess the efficacy of immune checkpoint inhibitors (ICIs) (PD-1/L1 and CTLA-4 inhibitors) in first and subsequent lines in East Asians and non-East Asians.
Methods: We searched PubMed-MEDLINE, Embase and Scopus, from inception to 20 Sep 2019, and reviewed major conferences' abstracts, for randomised controlled trials of ICI in advanced-stage NSCLC (Stage IIIB or IV) without EGFR mutation that reported hazard ratios (HRs) stratified by geographical region including the region "Asia" or "East Asia". The primary outcome measures were overall survival (OS) and progression-free survival (PFS). The pooled HR and its 95% confidence interval (CI) for OS and PFS in East Asians and non-East Asians were calculated using a random effect model and the difference compared using an interaction test.
Results: A total of 5,465 patients from 7 randomised controlled trials involving CTLA-4 and/or PD-1/L1 inhibitors were included, with 1,740 (32%) East Asians and 3,725 (68%) non-East Asians. ICI was associated with an improvement in OS and PFS for both East Asian (OS HR, 0.74; 95% CI, 0.65-0.85; PFS HR, 0.56; 95% CI, 0.40-0.79) and non-East Asian patients (OS HR, 0.78; 95% CI, 0.72-0.85; PFS HR, 0.69; 95% CI, 0.56-0.85), with no significant difference between the two groups (Pinteraction=0.55 for OS; Pinteraction=0.33 for PFS). Subgroup analyses showed a statistically significant superior PFS (but not OS) for East Asians than non-East Asians in trials that used immune checkpoint inhibitor in the first-line treatment (Pinteraction=0.02). No significant regional difference was found in further subgroups of pure ICI and combination of ICI with chemotherapy.
Conclusions: There is no significant difference in response to ICI between East Asians and non-East Asians with advanced stage NSCLC, and the statistically significant subgroup difference in PFS in the first line use of ICI may not be clinically significant.

Malaysian Journal of Medicine and Health Sciences, 2019;15(104):106-106.
MyJurnal

Introduction: Malaysia has been nominated among the top four well-established healthcare system in the world. However, with the status of a developing country, there are still lacking in offering healthcare services and aware-ness among poverty. The objective of this review is to look into the factors hindering healthcare coverage in poverty. Methods: These literature reviews were carried out by using the electronic databases included, Google Scholars, Medline, PUBMED and EBSCOhost. Results: In current economic status, poverty status needs to be revised as the cost of living has markedly increased especially in the urban. Many factors affect the health status, which include the issues in term of rising health expenditure, demography-geography and imbalance workload distribution. Less expo-sure to health and wellness and geographical-demographic profile are the main reasons for the lack of self-awareness in assessing health services. Various actions had been taken by the stakeholders to improve health statuses such as telehealth, referral system and integration between agencies. Suggestion to improve the existing plan with the atten-tion given especially in the rural area which composed of multi-ethnicity and demography-geographical distribution. In Islam, Prophet Muhammad PBUH promotes health through his eating habits, physical activities include prayer and sports, proper sleep habit and through fasting. Conclusion: Poor and lack of awareness of healthcare services and health ownership have been the main reason for low health-seeking in poverty. Factors such as rising health expenditure, demography-geography factors and lack of facilities provided and unbalance workload distribution in the public-private sector contribute to the issue of concern.

Zhu CZ, Ting HN, Ng KH, Ong TA

J Cancer, 2019;10(17):4038-4044.
PMID: 31417648 DOI: 10.7150/jca.28989

Background and purpose: Bladder cancer is the most common malignant tumour in the urinary system, with a high incidence and recurrence rate. While the incidence of bladder cancer has been rising in recent years, the prevalence of bladder carcinoma is showing an increasing tendency in the younger age group. There are several methods to detect bladder cancer, but different methods have varying degrees of accuracy which intrinsically depends on the method's sensitivity and specificity. Our aim was to comprehensively summarize the current detection methods for bladder cancer based on the available literature, and at the same time, to find the best combination of different effective methods which can produce a high degree of accuracy in detecting the presence of cancerous cells in the bladder. Materials and Methods: We used key word retrieval method for searching related references in English that had been indexed in PubMed and Medline. Results and Discussion: This paper discussed the different detection methods and their sensitivities/specificities as well as the advantages and disadvantages. We summarized the best identified cancer cell detection methods with higher sensitivity/specificity. Conclusion: The results of this review can positively help to identify accurate methods for detecting bladder cancer and highlight areas to be further improved for future research work.

Fulltext A systematic literature review on technology-enhanced learning in medical education

May Honey Ohn

Borneo Journal of Medical Sciences, 2020;14(1):3-17.
MyJurnal

This systematic review was aimed to evaluate the effectiveness of technology-enhanced learning (TEL) used in medical teaching for undergraduate medical students. The objectives are to (a) identify various teaching modalities which are used to enhance TEL; (b) evaluate whether TEL is more effective than traditional learning (TL) in cognitive and affective learning domain outcome. The empirical studies were searched in the following databases: Google Scholar, MEDLINE, ERIC, ProQuest, Cochrane Library and Scopus. All papers published from 2008 to 2018 were included. From eligible studies, the study design, study field, study population, intervention methods, type of assessment and learning achievement were abstracted and summarized the information. The search results were independently reviewed by two authors. From a pool of 1384 articles, 43 eligible articles were identified, enrolling 7292 undergraduate medical students examining comparative study between TEL and traditional learning. The results showed that there was a high degree of heterogeneity seen amongst the included studies in terms of TEL modalities used. The majority of intervention studies favoured online resources, while the rest used various offline multimedia electronic devices, virtual simulations and blended modes. Overall findings showed promising data that TEL is better than TL with regards to knowledge gain and skill acquisition, as well as providing higher student satisfaction. In all, the findings present blended learning in a positive and promising light in time, particularly where systematic reviews on technology-enhanced learning in the field of the undergraduate medical programme have produced mixed result.REVIEW ARTICLEA Systematic Literature Review on Technology-Enhanced Learning in Medical EducationMay Honey Ohn1*, Bareth Ravindran2, Chan Zhi Wei3, Khin Maung Ohn4, Ng Pey Luen5Borneo Journal of Medical Sciences 14 (1) January, 2020: 3 – 171 Emergency Department, Sandwell & West Birmingham NHS Trust, United Kingdom2 Surgical Department, Hospital Tuanku Ja’afar Seremban, Kuala Lumpur, Malaysia3 Orthopaedics Department, Hospital Sungai Buloh, Kuala Lumpur, Malaysia4 Department of Surgery, Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah, Kota Kinabalu, Sabah, Malaysia5 Radiology Department, Hospital Queen Elizabeth II, Sabah, Malaysia* Corresponding author’s email: mayhoney.ohn@gmail.com Received: 14 July 2019 Accepted: 5 November 2019Borneo Journal of Medical SciencesBJMSKeywords: blended learning, technology-enhanced learning, medical education, hybrid learning, undergraduate medical students

A systematic review of the prevalence of limited health literacy in Southeast Asian countries

Rajah R, Hassali MAA, Murugiah MK

Public Health, 2019 Feb;167:8-15.
PMID: 30544041 DOI: 10.1016/j.puhe.2018.09.028

OBJECTIVES: Health literacy is increasingly recognized as a public health concern. Most of the literature on health literacy concentrate in the Western countries. Therefore, this study aimed to systematically review and examine the available studies on health literacy in Southeast Asian countries and estimate its prevalence in this region.
STUDY DESIGN: Systematic review.
METHODS: A search for relevant articles was carried out using Cumulative Index to Nursing and Allied Health Literature (CINAHL) and MEDLINE (via EBSCOhost), Scopus, Science Direct, PubMed and Google Scholar with multiple search terms. Inclusion criteria comprised articles published in English language and assessing general health literacy. Risk of bias reduced with the involvement of two independent reviewers in the screening of the literature and the quality assessment process.
RESULTS: A total of 11 studies were included, which only consist of studies from five countries out of 11 making up the Southeast Asian region. The overall prevalence of limited health literacy varied considerably, 1.6%-99.5% with a mean of 55.3% (95% confidence interval [CI]: 35.1%-75.6%). A much higher prevalence was noted in studies conducted in healthcare settings, 67.5% (95% CI: 48.6%-86.3%). The most common factors associated with limited health literacy were education attainment, age, income and socio-economic background. Other factors identified were gender and health behaviours.
CONCLUSIONS: In summary, despite the little evidence available and existences of high heterogeneity among studies, limited health literacy is still prevalent in Southeast Asian countries. Urgent strategies to improve and promote health literacy in the region are highly warranted. Besides, more studies on health literacy with better quality on the methodology aspect are needed.

Fulltext Adiponectin, Leptin and Objectively Measured Physical Activity in Adults: A Narrative Review

Nurnazahiah A, Lua PL, Shahril MR

Malays J Med Sci, 2016 Nov;23(6):7-24.
PMID: 28090175 MyJurnal DOI: 10.21315/mjms2016.23.6.2

The objective of this study was to compile and analyse existing scientific evidences reporting the effects of objectively measured physical activity on the levels of adiponectin and leptin. Articles related to the effects of objectively measured physical activity on the levels of adiponectin and leptin were searched from the Medline and PubMed databases. The search was limited to 'objectively measured' physical activity, and studies that did not objectively measure the physical activity were excluded. Only English articles were included in the search and review. A total of 18 articles encompassing 2,026 respondents met the inclusion criteria. The eligible articles included all forms of evidence (e.g., cross-sectional and intervention). Seventeen and 11 studies showed the effects of objectively measured physical activity on adiponectin and leptin, respectively. Five and four cross-sectional studies showed the effects of objectively measured physical activity on adiponectin and leptin, respectively. Two out of five studies showed a weak to moderate positive association between adiponectin and objectively measured physical activity, while three out of four studies showed a weak to moderate inverse association between leptin and objectively measured physical activity. For intervention studies, six out of 12 studies involving adiponectin and five out of seven studies involving leptin showed a significant effect between the proteins and objectively measured physical activity. However, a definitive conclusion could not be drawn due to several methodological flaws in the existing articles and the acute lack of additional research in this area. In conclusion, the existing evidences are encouraging but yet not compelling. Hence, further well-designed large trials are needed before the effectiveness of objectively measured physical activity in elevating adiponectin levels and in decreasing leptin levels could be strongly confirmed.

Haque S, Alam MK, Arshad AI

Malays J Med Sci, 2015 Jan-Feb;22(1):4-11.
PMID: 25892945 MyJurnal

In the contemporary era, the demand for orthodontic treatment is ever rising. Orthodontic treatment duration can range from a year to a few years. Our aim is to assess the available techniques of categorising treatment effectiveness in patients with cleft lip and palate (CLP) and to study their effect on improvement of treatment outcomes. The electronic databases including Medline-PUBMED, Science Direct, and ISI Web of Knowledge were searched from 1987 to 2013, and 40 311 relevant articles were found. Of these, we identified 22 articles including original articles as well as literature reviews. The different parameters and indices that are applied to speed-up orthodontic treatment outcomes in patients with CLP were identified as the GOSLON Yardstick, 5-year-old index, EUROCRAN index, Huddart Bodenham system, modified Huddart Bodenham system, GOAL Yardstick and, Bauru-Bilateral Cleft Lip and Palate Yardstick. This overview can create better awareness regarding the uses, advantages, and disadvantages of the different indices. It can enable better assessment and provide the impetus needed for a sustained upgrade in the standards of care for CLP in daily orthodontics.

Fulltext An update of the Malaysian Clinical Guidance on the management of glucocorticoid-induced osteoporosis, 2015

Yeap SS, Hew FL, Damodaran P, Chee W, Lee JK, Goh EML, et al.

Osteoporos Sarcopenia, 2017 Mar;3(1):1-7.
PMID: 30775497 DOI: 10.1016/j.afos.2017.01.001

Objectives: This Clinical Guidance is aimed to help practitioners assess, diagnose and manage their patients with glucocorticoid-induced osteoporosis (GIO), using the best available evidence.

Methods: A literature search using PubMed (MEDLINE) and The Cochrane Library identified all relevant articles on GIO and its assessment, diagnosis and treatment, from 2011, to update from the 2012 edition. The studies were assessed and the level of evidence assigned. For each statement, studies with the highest level of evidence were used to frame the recommendation.

Results: Consider treatment early in all patients on glucocorticoids (GC) as fracture risk increases within 3-6 months of starting GC. The decision to start treatment for GIO depends on the presence of prior fracture, category of risk (as calculated using Fracture Risk Assessment Tool), daily dose and duration of GC treatment, age, and menopausal status. General measures include adequate calcium and vitamin D intake and reducing the dose of GC to the minimum required to achieve disease control. In patients on GC with osteoporotic fractures or confirmed osteoporosis on dual-energy X-ray absorptiometry, bisphosphonates are the first-line treatment. Treatment should be continued as long as patients remain on GC. Algorithms for the management of GIO in both pre- and post-menopausal women and men have been updated.

Conclusions: In post-menopausal women and men above 50 years, bisphosphonates remain the mainstay of treatment in GIO. In pre-menopausal women and men below 50 years, bisphosphonates are recommended for those with a prevalent fracture or at very high risk only.

Fulltext Anterior-Alone Surgical Treatment for Subaxial Cervical Spine Facet Dislocation: A Systematic Review

Lee W, Wong CC

Global Spine J, 2021 Mar;11(2):256-265.
PMID: 32875872 DOI: 10.1177/2192568220907574

STUDY DESIGN: Systematic review.
OBJECTIVE: Anterior-alone surgery has gained wider reception for subaxial cervical spine facets dislocation. Questions remain on its efficacy and safety as a stand-alone entity within the contexts of concurrent facet fractures, unilateral versus bilateral dislocations, anterior open reduction, and old dislocation.
METHODS: A systematic review was performed with search strategy using translatable MESH terms across MEDLINE, EMBASE, VHL Regional Portal, and CENTRAL databases on patients with subaxial cervical dislocation intervened via anterior-alone approach. Two reviewers independently screened for eligible studies. PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) flow chart was adhered to. Nine retrospective studies were included. Narrative synthesis was performed to determine primary outcomes on spinal fusion and revisions and secondary outcomes on new occurrence or deterioration of neurology and infection rate.
RESULTS: Nonunion was not encountered across all contexts. A total of 0.86% of unilateral facet dislocation (1 out of 116) with inadequate reduction due to facet fragments between the facet joints removed its malpositioned plate following fusion. No new neurological deficit was observed. Cases that underwent anterior open reduction did not encounter failure that require subsequent posterior reduction surgery. One study (N = 52) on old dislocation incorporated partial corpectomy in their approach and limited anterior-alone approach to cases with persistent instability.
CONCLUSIONS: This systematic review supports the efficacy and success of anterior reduction, fusion, and instrumentation for cervical facet fracture dislocation. It is safe from a neurological standpoint. Revision rate due to concurrent facet fracture is low. Certain patients may require posteriorly based surgery or in specific cases combined anterior and posterior procedures.

Fulltext Antibacterial-Integrated Collagen Wound Dressing for Diabetes-Related Foot Ulcers: An Evidence-Based Review of Clinical Studies

N Amirrah I, Mohd Razip Wee MF, Tabata Y, Bt Hj Idrus R, Nordin A, Fauzi MB

Polymers (Basel), 2020 Sep 22;12(9).
PMID: 32972012 DOI: 10.3390/polym12092168

Diabetic foot ulcer (DFU) is a chronic wound frequently delayed from severe infection. Wound dressing provides an essential barrier between the ulcer and the external environment. This review aimed to analyse the effectiveness of antibacterial collagen-based dressing for DFU treatment in a clinical setting. An electronic search in four databases, namely, Scopus, PubMed, Ovid MEDLINE(R), and ISI Web of Science, was performed to obtain relevant articles published within the last ten years. The published studies were included if they reported evidence of (1) collagen-based antibacterial dressing or (2) wound healing for diabetic ulcers, and (3) were written in English. Both randomised and non-randomised clinical trials were included. The search for relevant clinical studies (n) identified eight related references discussing the effectiveness of collagen-based antibacterial wound dressings for DFU comprising collagen impregnated with polyhexamethylene biguanide (n = 2), gentamicin (n = 3), combined-cellulose and silver (n = 1), gentian violet/methylene blue mixed (n = 1), and silver (n = 1). The clinical data were limited by small sample sizes and multiple aetiologies of chronic wounds. The evidence was not robust enough for a conclusive statement, although most of the studies reported positive outcomes for the use of collagen dressings loaded with antibacterial properties for DFU wound healing. This study emphasises the importance of having standardised clinical trials, larger sample sizes, and accurate reporting for reliable statistical evidence confirming DFU treatment efficiency.

Fulltext Are Malaysians getting fatter and rounder?: an updated systematic review (2009 – 2015)

Tan, Siew-Tin, Sherina Mohd-Sidik, Rampal, Lekhraj, Normala Ibrahim, Tan, Kit-Aun

Malaysian Journal of Medicine and Health Sciences, 2019;15(1):63-77.
MyJurnal

Overweight and obesity have become a serious health issue in worldwide and Malaysia is no exception. In view that obesity is one of the leading causes of non-communicable diseases, this systematic review aimed to explore whether Malaysian are getting fatter (overweight or obesity) and rounder (abdominal obesity). Searches of the published literature were conducted using 3 databases including EMBASE, MEDLINE, and PubMed. These were limited to cross-sectional or cohort studies in Malaysia. The databases provided the prevalence of overweight, obesity, and abdominal obesity among 15 years old and above Malaysian population from 2009 to 2015. In total, 47 articles were included in this review. Findings exhibit that the prevalence rates of overweight, obesity, and abdominal obesity range from 9.5% to 43.5%, 1.77% to 26.4% and 11.4% to 57.4%, respectively. Overweight is more predominant among males. However, obesity and abdominal obesity are more predominant among females. This means that more females are getting fatter and “rounder” as compared to males in Malaysia. The findings imply a lack of intervention programmes based on proper randomized controlled trials which are needed to adequately address the problem of obesity in Malaysia.

Fulltext Association of ABO blood groups with allergic diseases: a scoping review

Dahalan NH, Tuan Din SA, Mohamad SMB

BMJ Open, 2020 02 12;10(2):e029559.
PMID: 32051294 DOI: 10.1136/bmjopen-2019-029559

OBJECTIVE: The objective of this study was to map evidence of the association of ABO blood groups with allergic diseases such as allergic rhinitis (AR), atopic dermatitis (AD) and asthma.
DESIGN: A scoping review.
DATA SOURCES: PubMed, Scopus, Direct Open Access Journal, Medline, Cumulative Index to Nursing and Allied Health Literature, ScienceDirect and SpringerLink were searched from October 2017 until May 2018.
ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We selected all types of studies including case-control studies, prospective or retrospective cohort studies, cross-sectional studies and experimental studies, and we included reviews such as literature reviews, systematic reviews with or without meta-analysis and scoping reviews that were published in English and associated the ABO blood group with the three allergic diseases (asthma, AR and AD) in humans of all age groups.
DATA EXTRACTION AND SYNTHESIS: Two reviewers independently screened the titles and abstracts and assessed the full-text articles of the abstracts that met the eligibility requirements. Data from the included studies were extracted, evaluated and reported in the form of narrative synthesis.
RESULTS: Of the 10 246 retrieved titles, only 14 articles were selected for a scoping review based on the eligibility criteria. The majority of the studies demonstrated a significant association between ABO blood groups and allergic diseases. We found that blood group O is prominent in patients with AR and asthma, while a non-O blood group is common in patients with AD.
CONCLUSION: This scoping review serves as preliminary evidence for the association of ABO blood groups with allergic diseases. Further studies need to be conducted so that the relationship between ABO blood groups and allergic diseases can be fully established. This could be helpful for clinicians and health professionals in consulting and managing patients who suffer from allergic diseases in the future.

Fulltext Augmentation of the Female Reproductive System Using Honey: A Mini Systematic Review

Ismail NH, Ibrahim SF, Jaffar FHF, Mokhtar MH, Chin KY, Osman K

Molecules, 2021 Jan 27;26(3).
PMID: 33513715 DOI: 10.3390/molecules26030649

Phytochemical contents of honey are presumed to be beneficial to the female reproductive system (FRS). However, the biological effects of honey supplementation (HS) in vivo on the FRS remain unclear. This review aims to investigate the current literature on the effects of HS on the FRS, particularly on the sex hormone profile and reproductive organs (uterus and vagina). A systematic literature search using Scopus, MEDLINE via Ovid and Cochrane Library databases was conducted. Records were screened and identified for preclinical and clinical studies addressing the effects of HS on the FRS. Data on populations, interventions, outcomes and methodological quality were extracted. Studies were synthesised using tables and written summaries. Of the 198 identified records, six fulfilled the inclusion criteria. All six records were used for data extraction: two experimental studies using rats as the model organism and four human clinical studies of honey on female reproductive health. HS elevated the progesterone levels, restrained body weight increase, prevented uterine and vaginal atrophies in ovariectomised rats, attenuated symptoms of candidiasis and improved oxidative status in patients. Current evidence shows that short-term HS following surgical or physiological menopause exerts an oestrogenic, antioxidant and anti-inflammatory effect on the FRS. However, insufficient long-term studies preclude any definitive conclusions.

Fulltext Averrhoa bilimbi Linn.: A review of its ethnomedicinal uses, phytochemistry, and pharmacology

Alhassan AM, Ahmed QU

J Pharm Bioallied Sci, 2016 Oct-Dec;8(4):265-271.
PMID: 28216948 DOI: 10.4103/0975-7406.199342

Averrhoa bilimbi Linn. is principally cultivated for medicinal purposes in many tropical and subtropical countries of the world. Literature survey about this plant shows that A. bilimbi is mainly used as a folk medicine in the treatment of diabetes mellitus, hypertension, and as an antimicrobial agent. The prime objective of this review is to accumulate and organize literature based on traditional claims and correlate those with current findings on the use of A. bilimbi in the management of different ailments. Through interpreting already published scientific manuscripts (1995 through 2015) retrieved from the different scientific search engines, namely Medline, PubMed, EMBASE, and Science Direct databases, published articles and reports covering traditional and scientific literature related to A. bilimbi's potential role against various ailments have been thoroughly evaluated, interpreted, and discussed. Several pharmacological studies have demonstrated the ability of this plant to act as antidiabetic, antihypertensive, thrombolytic, antimicrobial, antioxidant, hepatoprotective, and hypolipidemic agent. A. bilimbi holds great value in the complementary and alternative medicine as evidenced by the substantial amount of research on it. Therefore, we aimed to compile an up-to-date and comprehensive review of A. bilimbi that covers its traditional and folk medicine uses, phytochemistry, and pharmacology. Hence, this paper presents an up-to-date and comprehensive review of the ethnomedicinal uses, different chemical constituents, and pharmacological activities of A. bilimbi. So far, the biologically active agents have not been isolated from this plant and this can be a good scientific study for the future antidiabetic, antihypertensive, and antimicrobial implications. Hence, this review targets at emphasizing the diverse traditional claims and pharmacological activities of A. bilimbi with respect to carrying out more scientific studies to isolate active principles through advanced technology.

Biological activities of Anastatica hierochuntica L.: A systematic review

Zin SRM, Kassim NM, Alshawsh MA, Hashim NE, Mohamed Z

Biomed Pharmacother, 2017 Jul;91:611-620.
PMID: 28486192 DOI: 10.1016/j.biopha.2017.05.011

Anastatica hierochuntica L. (A. hierochuntica) is a desert plant consumed by people across the globe to treat various medical conditions. This review is aimed at providing a summary of the scientific findings on biological activities of A. hierochuntica and suggests areas in which further research is needed. This systematic review was synthesized from the literature obtained from the following databases; PubMed, Science Direct, Web of Science, Ovid Medline, Scopus, Google Scholar and WorldCat. Previous studies have indicated that the methanolic and aqueous extracts of this plant have antioxidant, antifungal and antimicrobial activities. It was shown to have the ability to activate phagocytes and to possess microbicidal activity, thereby causing increased resistance to infection. Both methanolic and aqueous extracts of this plant were also demonstrated to have a hypoglycaemic property, whilst the methanolic extract significantly exhibited hypolipidaemic effects in diabetic rats. Moreover, the methanolic extract of A. hierochuntica has been suggested to have hepatoprotective properties. This is supported by its ability to significantly decrease transaminase and alkaline phosphatase activities in alloxan-induced diabetic rats. Besides, this desert plant exhibited anti-inflammatory, anti-melanogenic and gastroprotective activities. Even though A. hierochuntica is widely used, studies on this plant are still scarce, thus its reputed biological activities and medical benefits require critical evaluation. Before A. hierochuntica can be used clinically, further studies need to be conducted to increase our understanding of the effects of this plant, its constituents, and possible mechanisms of action.

Nutr Neurosci, 2020 Dec 14.
PMID: 33314992 DOI: 10.1080/1028415X.2020.1853411

OBJECTIVE: Several studies have been conducted on the relationship between breakfast consumption and mental health with conflicting results. Therefore, the present systematic review and meta-analysis was undertaken to summarize evidences on the association between skipping breakfast and mental health.
METHODS: We searched online databases for all related papers through the comprehensive international data bases of Institute of PubMed/ MEDLINE, ISI/WOS and Scopus up to December 2019, using relevant keywords. Overall, 14 studies were included in this systematic review and meta-analysis.
RESULTS: The total sample size of all selected studies was 399,550 individuals with age range of 6 to ≥65 years old. We found a significant positive association between skipping breakfast and Odds Ratio (OR) of depression (pooled OR: 1.39; 95% CI: 1.34-1.44), stress (pooled OR: 1.23; 95% CI: 1.04-1.43) and psychological distress (pooled OR: 1.55; 95% CI: 1.47-1.62). In contrast, there was no significant association between skipping breakfast and anxiety in all age cohort (pooled OR: 1.31; 95% CI: 0.97-1.65). However, subgroup analysis based on age stratification showed that there was a significant positive association between skipping breakfast and anxiety in adolescences (pooled OR: 1.51; 95% CI: 1.25-1.77).
CONCLUSION: In conclusion, skipping breakfast was positively associated with odds of depression, stress and psychological distress in all age groups and anxiety in adolescence, underlining impact of breakfast on mental health.

Fulltext Cannabis sativa subsp. sativa's pharmacological properties and health effects: A scoping review of current evidence

Lim XY, Tan TYC, Muhd Rosli SH, Sa'at MNF, Sirdar Ali S, Syed Mohamed AF

PLoS One, 2021;16(1):e0245471.
PMID: 33465140 DOI: 10.1371/journal.pone.0245471

INTRODUCTION: Hemp (Cannabis sativa subsp. sativa), commonly used for industrial purposes, is now being consumed by the public for various health promoting effects. As popularity of hemp research and claims of beneficial effects rises, a systematic collection of current scientific evidence on hemp's health effects and pharmacological properties is needed to guide future research, clinical, and policy decision making.
OBJECTIVE: To provide an overview and identify the present landscape of hemp research topics, trends, and gaps.
METHODS: A systematic search and analysis strategy according to the preferred reporting items for systematic review and meta-analysis-ScR (PRISMA-ScR) checklist on electronic databases including MEDLINE, OVID (OVFT, APC Journal Club, EBM Reviews), Cochrane Library Central and Clinicaltrials.gov was conducted to include and analyse hemp research articles from 2009 to 2019.
RESULTS: 65 primary articles (18 clinical, 47 pre-clinical) were reviewed. Several randomised controlled trials showed hempseed pills (in Traditional Chinese Medicine formulation MaZiRenWan) improving spontaneous bowel movement in functional constipation. There was also evidence suggesting benefits in cannabis dependence, epilepsy, and anxiety disorders. Pre-clinically, hemp derivatives showed potential anti-oxidative, anti-hypertensive, anti-inflammatory, anti-diabetic, anti-neuroinflammatory, anti-arthritic, anti-acne, and anti-microbial activities. Renal protective effects and estrogenic properties were also exhibited in vitro.
CONCLUSION: Current evidence on hemp-specific interventions are still preliminary, with limited high quality clinical evidence for any specific therapeutic indication. This is mainly due to the wide variation in test item formulation, as the multiple variants of this plant differ in their phytochemical and bioactive compounds. Future empirical research should focus on standardising the hemp plant for pharmaceutical use, and uniformity in experimental designs to strengthen the premise of using hemp in medicine.

MyJurnal

Objective: To conduct a systematic review of identifying the clinical efficacy of caries preventive interventions in community-dwelling elders. Background: As the human lifespan increases, the elders are known to retain their teeth for longer. Therefore, the need to uncover effective ways of preventing caries among this age group is relevant. Methods: A search was conducted using four databases: Cochrane, MEDLINE, EMBASE and Web of Science using the keywords (caries OR demineralization) AND prevention AND (adult OR aged). The titles and abstracts were initially screened for the use of caries prevention interventions. Studies were excluded based on the predetermined criteria. The full texts of the remaining studies were then evaluated. Results: Of 6952 articles identified from the search, fifty full texts were evaluated. Finally, ten studies were analyzed. One study found rinsing with 0.05% of NaF twice daily resulted in lower coronal caries increment. Another study reported the use of 1,100 ppm of NaF dentifrice twice daily showed lower percentage of coronal and root caries. A reduction of root caries was observed from using 5,000 ppm fluoridated toothpaste twice daily, annual professional 38% SDF solution application, six-monthly professional cleaning and APF gel application. The use of 0.12% CHX rinse and xylitol chewing gum did not show reduction of caries incidence. Conclusion: Toothbrushing with 5,000 ppm of NaF dentifrice, rinsing with 0.05% NaF, professional application of 38% SDF solution and APF gel may be effective at preventing caries among the elders.

Cognitive behavioural therapy can be effective in treating anxiety and depression in persons with dementia: a systematic review

Tay KW, Subramaniam P, Oei TP

Psychogeriatrics, 2019 May;19(3):264-275.
PMID: 30548731 DOI: 10.1111/psyg.12391

Dementia is a neurocognitive disorder that affects a person's abilities in daily functioning. Anxiety and depression symptoms are common among persons with dementia. Cognitive behavioural therapy (CBT) has been tested to manage their depression and anxiety symptoms. However, the purpose of CBT in managing these symptoms is unclear. Therefore, this paper aims to clarify whether CBT can be used to reduce depression and anxiety symptoms in persons with dementia. The electronic databases PubMed, PsycINFO, MEDLINE, and CINAHL were used to locate relevant studies. Eleven studies, which involved a total of 116 older adults, were identified. The findings suggest that CBT can be effective in reducing depression and anxiety symptoms. Based on our current review, the findings from previous studies form a promising foundation on which to conduct a major randomized controlled trial with a larger sample size. This review discusses some of the most important considerations in applying CBT to persons with dementia, and these may be beneficial for future studies that explore this area and seek more conclusive evidence on the use of CBT.

Facial anthropometric data has significant ethnic variation. East Asia, comprised of fourteen countries, represents a significant proportion of the global population. This systematic review presents the facial anthropometric data collected from these countries. The systematic review was conducted in accordance with PRISMA guidelines. An electronic search of the MEDLINE database returned 3054 articles. Twenty articles were considered eligible for inclusion. Nine studies were conducted in China, 1 in Indonesia, 2 in Japan,3 in Korea, 4 in Malaysia, and 1 was a multicentre study conducted in China, Japan, Thailand, and Vietnam. Qualitative and quantitative parameters were extracted from the20 studies. No data was found for the other East Asian countries. There is a paucity of facial anthropometric data for East Asian countries despite their high burden of craniofacial anomalies and a strong demand for cosmetic facial surgery, both of which would benefit from the collection of robust craniofacial norms. It is in the interest of both the craniofacial surgeon and the East Asian patient to collect baseline facial anthropometric data for this population.
