    Blastocystis is a ubiquitous waterborne parasite that has been implicated in some disease conditions including colorectal cancer and irritable bowel syndrome, and its surface coat characteristics have been associated with its pathogenicity. Although the morphology of Blastocystis isolates from human and animal sources have been studied, there is a paucity of data on the surface ultrastructure of Blastocystis isolated from water sources. Therefore, this study aimed to determine the occurrence and the ultrastructural surface of Blastocystis isolates from several water sources in Kedah and Penang, Malaysia. A total of 12 water samples were collected, namely, Pinang River and USM Harapan Lake all in Penang, whereas Lata Bayu Waterfall in Baling and UniSHAMS Lake, Kuala Ketil in Kedah. These were examined for Blastocystis by centrifugation and in vitro cultivation. Scanning electron microscopy (SEM) and light microscopy were employed to study the morphological characteristics and the surface ultrastructure of the parasite. Polymerase chain reaction (PCR) was carried out to obtain the subtypes (ST) of the positive Blastocystis isolates. The result revealed 25.0% (3/12) contamination with Blastocystis in which ST1, ST2, and an unknown ST (with a high similarity to ST1) were detected in water samples from the upstream, downstream, and midstream, respectively of Pinang River. Our study also revealed similarities in the sizes of the isolates from different river points, which were notably more diminutive compared to the sizes of the parasites observed in existing data from human and animal isolates. The surface characteristics showed a collection of single and dividing cells with smooth, folded surfaces enclosed in a film-like layer. Additionally, there were roundish, irregularly shaped cells with rough surfaces, and a woolly appearance. This study has added to our knowledge of the surface ultrastructure of Blastocystis and its possible contribution to the pathogenicity of the parasite.

    Current strategies for tick control have led to the development of resistance and environmental contamination. Consequently, there is an urgent need for research into new and effective acaricides for tick control. The aim of this study was to fabricate and characterize Linalool loaded zinc oxide nanoparticles (Lin@ZNP), and to assess the acaricidal, larvacidal, and repellent activities of Lin@ ZNP against Hyalomma anatolicum, a prevalent tick species infesting cattle in Saudi Arabia. Lin@ ZNP was synthesized using an ethanolic solution of polyvinyl alcohol. The adult immersion, the larval packet, and the assessment of vertical movement behavior of tick larvae assays were utilized to examine the acaricidal, larvicidal, and repellent activities of Lin@ZNP against H. anatolicum, respectively. Furthermore, the impact of Lin@ZNP on acetylcholinesterase and oxidant/antioxidant enzyme activities was investigated. Exposure of adult H. anatolicum to different concentrations of Lin@ZNP resulted in noticeable (p<0.001) reductions in the viability rate of adults and the mean number, weight, and hatchability of eggs, compared to the control group. Lin@ZNP demonstrated significant repellent effects on H. anatolicum larvae after 60, 120, and 180 minutes of exposure. Lin@ZNP, particularly at all concentrations, markedly suppressed the acetylcholinesterase activity of the larval stage of H. anatolicum (P<0.001); but increase in malondialdehyde (MDA) levels (P<0.001) and a decrease in glutathione-S-transferase (GST) levels in H. anatolicum larvae (P<0.001). Lin@ZNP exhibited considerable acaricidal, larvicidal, and repellent effects against H. dromedarii adults and larvae in a manner dependent on the dosage. Additionally, Lin@ZNP notably reduced AChE levels and antioxidant activity, while inducing oxidative stress in H. anatolicum larvae. Nevertheless, further research is necessary to elucidate the precise mechanisms and practical efficacy of Lin@ZNP.

    Cold-active enzymes have recently gained popularity because of their high activity at lower temperatures than their mesophilic and thermophilic counterparts, enabling them to withstand harsh reaction conditions and enhance industrial processes. Cold-active lipases are enzymes produced by psychrophiles that live and thrive in extremely cold conditions. Cold-active lipase applications are now growing in the detergency, synthesis of fine chemicals, food processing, bioremediation, and pharmaceutical industries. The cold adaptation mechanisms exhibited by these enzymes are yet to be fully understood. Using phylogenetic analysis, and advanced deep learning-based protein structure prediction tool Alphafold2, we identified an evolutionary processes in which a conserved cold-active-like motif is presence in a distinct subclade of the tree and further predicted and simulated the three-dimensional structure of a putative cold-active lipase with the cold active motif, Glalip03, from Glaciozyma antarctica PI12. Molecular dynamics at low temperatures have revealed global stability over a wide range of temperatures, flexibility, and the ability to cope with changes in water and solvent entropy. Therefore, the knowledge we uncover here will be crucial for future research into how these low-temperature-adapted enzymes maintain their overall flexibility and function at lower temperatures.

    The 13-item Body Acceptance by Others Scale-2 (BAOS-2) measures generalised perceptions of body acceptance by others. Here, we examined the psychometric properties of a novel Italian translation of the BAOS-2. Studies 1 (N = 401) and 2 (N = 393) supported a unidimensional model of the Italian BAOS-2 with all 13 items retained through exploratory and confirmatory factor analysis, respectively. Study 2 also supported measurement invariance of the Italian BAOS-2 across gender identity, with the gender difference in observed scores not reaching significance. In Study 3 (N = 365), we supported the construct validity of the Italian BAOS-2. Specifically, we found evidence of convergent validity (significant associations with indices of positive body image), criterion-related validity (significant associations with pressure to conform to appearance ideals and psychological well-being), and incremental validity (body acceptance predicted body appreciation over-and-above appearance-related pressure). These results suggest that the psychometric properties of the Italian BAOS-2 are robust and that this instrument can be confidently utilised in future research with Italian adults.

    Nipah virus disease is a bat-borne zoonosis with person-to-person transmission, a case-fatality rate of 38-75%, and well recognised potential to cause a pandemic. The first reported outbreak of Nipah virus disease occurred in Malaysia and Singapore in 1998, which has since been followed by multiple outbreaks in Bangladesh and India. To date, no therapeutics or vaccines have been approved to treat Nipah virus disease, and only few such candidates are in development. In this Review, we aim to assess the safety and efficacy of the therapeutic options (monoclonal antibodies and small molecules) for Nipah virus disease and other henipaviral diseases to support prioritisation of drug candidates for further evaluation in clinical trials. At present, sufficient evidence exists to suggest trialling 1F5, m102.4, and remdesivir (alone or in combination) for prophylaxis and early treatment of Nipah virus disease. In addition to well designed clinical efficacy trials, in-vivo pharmacokinetic-pharmacodynamic studies are needed to optimise the selection and dosing of therapeutic candidates in animal challenge and natural human infection.

    BACKGROUND: Diabetes can be detected at the primary health-care level, and effective treatments lower the risk of complications. There are insufficient data on the coverage of treatment for diabetes and how it has changed. We estimated trends from 1990 to 2022 in diabetes prevalence and treatment for 200 countries and territories.

    METHODS: We used data from 1108 population-representative studies with 141 million participants aged 18 years and older with measurements of fasting glucose and glycated haemoglobin (HbA1c), and information on diabetes treatment. We defined diabetes as having a fasting plasma glucose (FPG) of 7·0 mmol/L or higher, having an HbA1c of 6·5% or higher, or taking medication for diabetes. We defined diabetes treatment as the proportion of people with diabetes who were taking medication for diabetes. We analysed the data in a Bayesian hierarchical meta-regression model to estimate diabetes prevalence and treatment.

    FINDINGS: In 2022, an estimated 828 million (95% credible interval [CrI] 757-908) adults (those aged 18 years and older) had diabetes, an increase of 630 million (554-713) from 1990. From 1990 to 2022, the age-standardised prevalence of diabetes increased in 131 countries for women and in 155 countries for men with a posterior probability of more than 0·80. The largest increases were in low-income and middle-income countries in southeast Asia (eg, Malaysia), south Asia (eg, Pakistan), the Middle East and north Africa (eg, Egypt), and Latin America and the Caribbean (eg, Jamaica, Trinidad and Tobago, and Costa Rica). Age-standardised prevalence neither increased nor decreased with a posterior probability of more than 0·80 in some countries in western and central Europe, sub-Saharan Africa, east Asia and the Pacific, Canada, and some Pacific island nations where prevalence was already high in 1990; it decreased with a posterior probability of more than 0·80 in women in Japan, Spain, and France, and in men in Nauru. The lowest prevalence in the world in 2022 was in western Europe and east Africa for both sexes, and in Japan and Canada for women, and the highest prevalence in the world in 2022 was in countries in Polynesia and Micronesia, some countries in the Caribbean and the Middle East and north Africa, as well as Pakistan and Malaysia. In 2022, 445 million (95% CrI 401-496) adults aged 30 years or older with diabetes did not receive treatment (59% of adults aged 30 years or older with diabetes), 3·5 times the number in 1990. From 1990 to 2022, diabetes treatment coverage increased in 118 countries for women and 98 countries for men with a posterior probability of more than 0·80. The largest improvement in treatment coverage was in some countries from central and western Europe and Latin America (Mexico, Colombia, Chile, and Costa Rica), Canada, South Korea, Russia, Seychelles, and Jordan. There was no increase in treatment coverage in most countries in sub-Saharan Africa; the Caribbean; Pacific island nations; and south, southeast, and central Asia. In 2022, age-standardised treatment coverage was lowest in countries in sub-Saharan Africa and south Asia, and treatment coverage was less than 10% in some African countries. Treatment coverage was 55% or higher in South Korea, many high-income western countries, and some countries in central and eastern Europe (eg, Poland, Czechia, and Russia), Latin America (eg, Costa Rica, Chile, and Mexico), and the Middle East and north Africa (eg, Jordan, Qatar, and Kuwait).

    INTERPRETATION: In most countries, especially in low-income and middle-income countries, diabetes treatment has not increased at all or has not increased sufficiently in comparison with the rise in prevalence. The burden of diabetes and untreated diabetes is increasingly borne by low-income and middle-income countries. The expansion of health insurance and primary health care should be accompanied with diabetes programmes that realign and resource health services to enhance the early detection and effective treatment of diabetes.

    To shed light on the importance of tick-borne diseases, especially in farm animals that often contact with farm workers, this study aimed to identify ticks and tick-borne pathogens in ruminants in Malaysia. Accordingly, specimen collection was conducted across Peninsular Malaysia yielded a total of 1241 ticks collected from 674 farm ruminants. Among these, four tick species were identified, with Rhipicephalus microplus being the most prevalent, constituting 99.03 % of the total tick population. Analysis of 130 tick pools revealed three positives for Borrelia. BLAST analyses of the flaB and 16S rRNA genes revealed high similarities to Borrelia theileri, ranging from 98.78 to 100 % for flaB and 99.23-99.45 % for 16S rRNA. These results align with the phylogenetic trees, where sequences from both genes clustered together with B. theileri, further supporting this identification. No Rickettsia and Bartonella bacteria were detected. This study represents the first occurrence of B. theileri in R. microplus in Malaysia.

    BACKGROUND: Older adults with Benign Paroxysmal Positioning Vertigo (BPPV) may present with unsteadiness that affects gait patterns.

    OBJECTIVE: This study investigated the spatiotemporal gait parameters and indicators of turning difficulty during the Timed Up and Go (TUG) test in older adults with BPPV.

    METHODS: This case-controlled study collected data from older adults aged 65 and above with BPPV, young adults with BPPV and older adults without BPPV. Postural stability and self-perception of stability were measured using the Functional Gait Analysis and the Malay version of the Dizziness Handicap Inventory, respectively. The spatiotemporal gait parameters were recorded using a camera. The one-way ANOVA test was used for statistical analysis.

    RESULTS: Older adults with BPPV presented with alteration in gait parameters (time and number of steps) compared to older adults without BPPV and adults with BPPV during the TUG test (p

    Skin ageing results in wrinkling. In this study, we discuss four types of facial wrinkles: Crow's Feet wrinkles, forehead wrinkles, glabellar frown wrinkles, and nasolabial folds. These four phenotypes can be assessed either with a photo-numeric scale developed and validated on Caucasian skin (i.e., Caucasian scale) or with a photo-numeric scale developed and validated on Chinese skin (i.e., Chinese scale). As Caucasian and Chinese skin have inherent differences, the main objective of this study is to determine whether these inherent differences affect the suitability of evaluating facial wrinkles on ethnic Chinese skin with a Caucasian scale. Three trained assessors studied four types of wrinkles on the faces of 1,081 ethnic Chinese young adults from the Singapore/Malaysia Cross-sectional Genetics Epidemiology Study (SMCGES). We found that Caucasian scales and Chinese scales are concordant (Spearman's Rank Correlation (ρ) values: 0.53-0.80) and the level of agreement between the Caucasian scales and Chinese scales is moderately high (Cohen's Kappa (κ) values: 0.40-0.49). When tested on ethnic Chinese skin, both the Caucasian scale and the Chinese scale are largely consistent in showing presence or absence of a given facial wrinkle (Area under curve (AUC) values: 0.79-0.90). All assessors are highly internally consistent (Weighted Kappa (κw) values: 0.686-0.992). Our results build confidence that four types of facial wrinkles on ethnic Chinese faces can be assessed with Caucasian scales. To the best of our knowledge, Chinese scales for facial wrinkles beyond the four types discussed here have yet to be developed. Caucasian scales for these other facial wrinkles will also need to be tested for their suitability to be used on ethnic Chinese skin as and when more Chinese scales are developed.

    BACKGROUND: The growing use of telerehabilitation within the healthcare community has garnered substantial attention. In congruence with other healthcare fields, examining perceptions, barriers, and facilitators assumed paramount significance in the continuation and fortification of telerehabilitation practices among physiotherapists.

    OBJECTIVE: In this scoping review, we aimed to systematically map the literature on the perceptions of physiotherapists as well as the barriers and enablers of telerehabilitation in their daily practice.

    METHODS: The five-stage methodological framework recommended by Arksey and O'Malley (2005) was used for this scoping review. In the framework, eight databases were searched using key search terms such as "telerehabilitation", "physiotherapists", "readiness", "enablers" and "barriers" All findings were organised into perceptions and readiness, enablers, and barriers.

    RESULTS: Fourteen articles met the inclusion criteria and were categorized as: (1) perception and readiness, (2) enablers, and (3) barriers. In the perception and readiness category, new trends in healthcare, advancement in physiotherapy practices and the benefits to clients were identified. The enablers identified included prior training, personal experience, familiarity with technology, functional equipment and space, and client selection. The barriers to the adoption of telerehabilitation in physiotherapy practice are pinpointed to poor technology, communication hurdles, limited availability, lack of familiarity, and client-related concerns.

    CONCLUSION: While initial evidence suggests a generally positive perceptions it is important to consider both facilitators and barriers when understanding adoption. This review's findings revealed a wide research gap, with unequal weightage towards barriers compared to enablers, and highlights the need for further research. Developing telerehabilitation guidelines that cater to both physiotherapists and clients is necessary.

    OBJECTIVE: The administration of local anesthesia in intraperitoneal space as part of the multi-modal analgesic regimen has shown to be effective in reducing postoperative pain. Recent studies demonstrated that intraperitoneal lidocaine may provide analgesic effects. Primary objective was to determine the impact of intraperitoneal lidocaine on postoperative pain scores at rest.

    DESIGN: We carried out a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).

    METHODS: Databases of MEDLINE, EMBASE, and CENTRAL were searched from their inception date until May 2023. Randomized clinical trials (RCT) comparing intraperitoneal lidocaine and placebo in adults undergoing surgery were included.

    RESULTS: Our systematic review included 24 RCTs (n = 1824). The intraperitoneal lidocaine group was significantly associated with lower postoperative pain scores at rest (MD, -0.87, 95% CI, -1.04 to -0.69) and at movement (MD, -0.50, 95% CI, -0.93 to -0.08) among adult patients after surgery. Its administration also significantly decreased morphine consumption (MD, -6.42 mg, 95% CI, -11.56 to -1.27) and lowered the incidence of needing analgesia (OR, 0.22, 95% CI, 0.14 to 0.35). Intraperitoneal lidocaine statistically reduced time to resume regular diet (MD, 0.16 days; 95% CI, -0.31 to -0.01) and lowered postoperative incidence of nausea and vomiting (OR, 0.54, 95% CI, 0.39 to 0.75).

    CONCLUSIONS: In this review, our findings should be interpreted with caution. Future studies are warranted to determine the optimal dose of administering intraperitoneal lidocaine among adult patients undergoing surgery.

    OBJECTIVE: To determine the occurrence of breakthrough COVID-19 infections (BIs) in patients with systemic lupus erythematosus (SLE) compared with patients with other rheumatic autoimmune diseases (rAIDs), patients with non-rheumatic autoimmune diseases (nrAIDs), and healthy controls (HCs).

    METHODS: The study was based on data from 7035 fully vaccinated respondents to the online COVAD questionnaire with SLE (N = 852), rAIDs (N = 3098), or nrAIDs (N = 414), and HCs (N = 2671). BI was defined as COVID-19 infection occurring in individuals vaccinated with ≥ 2 doses (or 1 dose of J&J) ≥ 14 days after vaccination and not after 6 months since the last vaccine dose. Data were analysed using linear and logistic regression models.

    RESULTS: A total of 91/852 (10.7%) SLE patients reported at least one BI. The frequency of BIs in SLE patients was comparable to that among HCs (277/2671; p = 0.847) and patients with nrAID (39/414; p = 0.552) but higher than that among patients with other rAIDs (235/3098; p = 0.005). No demographic factors or treatments were associated with BIs in SLE patients (p ≥ 0.05 for all). Joint pain was more frequent in SLE patients than in HCs (odds ratio [OR]: 3.38; 95% confidence interval [CI]: 1.89-6.04; p

    OBJECTIVE: We conducted a systematic review of all available evidence on the feasibility and safety of minimally invasive coronary artery bypass grafting (MICS CABG) in patients with multivessel coronary artery disease (CAD).

    METHODS: A systematic literature search in PubMed, MEDLINE via Ovid, Embase, Scopus, and Web of Science was performed to identify all relevant studies evaluating outcomes of MICS CABG among patients with multivessel CAD and including at least 15 patients with no restriction on the publication date.

    RESULTS: A total of 881 studies were identified, of which 26 studies met the eligibility criteria. The studies included a total of 7,556 patients. The average patient age was 63.3 years (range 49.5 to 69.0 years), male patients were an average of 77.8% (54.0% to 89.8%), and body mass index was 29.8 kg/m2 (24.5 to 30.1 kg/m2). Early mortality and stroke were on average 0.6% (range 0% to 2.0%) and 0.4% (range 0% to 1.3%), respectively. The average number of grafts was 2.8 (range 2.1 to 3.7). The average length of hospital stay was 5.6 days (range 3.1 to 9.3 days).

    CONCLUSIONS: MICS CABG appears to be a safe method in well-selected patients with multivessel CAD. This approach is concentrated at dedicated centers, and there is no widespread application, although it has potential to be widely applicable as an alternative for surgical revascularization. However, large randomized controlled studies with longer follow-up are still required to compare the outcomes with conventional CABG and other revascularization strategies.

    INTRODUCTION: People with neurodegenerative disorders (ND) frequently face diagnostic delay and misdiagnosis. We investigated blood and cerebrospinal fluid (CSF) neurofilament light chain (NfL) to distinguish ND from primary psychiatric disorders (PPD), a common challenge in clinical settings.

    METHODS: Plasma and CSF NfL levels were measured and compared between groups, adjusting for age, sex, and weight.

    RESULTS: A total of 337 participants were included: 136 ND, 77 PPD, and 124 Controls. Plasma NfL was 2.5-fold elevated in ND compared to PPD and had strong diagnostic performance (area under the curve, [AUC]: 0.86, 81%/85% specificity/sensitivity) that was comparable to CSF NfL (2-fold elevated, AUC: 0.89, 95%/71% specificity/sensitivity). Diagnostic performance was especially strong in younger people (40-

    BACKGROUND: The COVID-19 comorbid population is at higher risk of developing severe health issues like acute respiratory distress syndrome, coagulation syndrome, metabolic acidosis, and septic shock, potentially leading to patient death. Patients' knowledge, attitudes, and practices (KAP) significantly influence their response to the pandemic and aid in enhancing health policy implementation.

    OBJECTIVE: To identify and evaluate the pattern and associated factors to COVID-19 knowledge, attitude, and practice among individuals with comorbidities.

    METHODOLOGY: The systematic review followed the PRISMA guidelines. Relevant studies assessing the KAP of comorbid patients were retrieved by carefully searching the PubMed and Google Scholar databases. The appraisal tool for cross-sectional studies was used to determine the quality of the included studies and the risk of biases.

    RESULTS: Eighteen studies met the inclusion criteria and were included in the review. The pooled sample size of the included studies was 9,104. Different comorbidities reported in the studies include hypertension, diabetes, psychological disorders, and cancer. Pooled analysis showed that 65% of patients showed good knowledge, 57% of patients showed a positive attitude and 51% of patients followed good practices to manage the COVID-19 in presence of their comorbid condition. Significant factors impacting knowledge, attitude and practice in COVID-19 comorbid patients were ethnicity OR 1.78 [95% CI 1.35-2.32]; educational status 3.2 [2.79-3.58]; urban residence 2.43 [1.65-3.02]; employment Status 1.67[1.34-2.12]; financial Status 4.02[3.66-4.38]; occupation 3.65[3.31-4.25]; information Source 2.64[2.19-3.26]; comorbidity 3.28[2.78-3.61]; and duration of chronic illness 1.59[1.31-2.04].

    CONCLUSION: Comorbid COVID-19 patients showed good knowledge, positive attitude and good practice towards the management of the disease.

    BACKGROUND: Dementia leads to progressive cognitive decline, and represents a significant health and societal burden. Its prevalence is growing, with Alzheimer's disease as the leading cause. There is no cure for Alzheimer's disease, but there are regulatory-approved pharmacological interventions, such as galantamine, for symptomatic relief. This review updates the 2006 version.

    OBJECTIVES: To assess the clinical effects, including adverse effects, of galantamine in people with probable or possible Alzheimer's disease or mild cognitive impairment, and to investigate potential moderators of effect.

    SEARCH METHODS: We systematically searched the Cochrane Dementia and Cognitive Improvement Group's Specialised Register on 14 December 2022 using the term 'galantamine'. The Register contains records of clinical trials identified from major electronic databases (including CENTRAL, MEDLINE, and Embase), trial registries, grey literature sources, and conference proceedings. We manually searched reference lists and collected information from US Food and Drug Administration documents and unpublished trial reports. We imposed no language restrictions.

    SELECTION CRITERIA: We included double-blind, parallel-group, randomised controlled trials comparing oral galantamine with placebo for a treatment duration exceeding four weeks in people with dementia due to Alzheimer's disease or with mild cognitive impairment.

    DATA COLLECTION AND ANALYSIS: Working independently, two review authors selected studies for inclusion, assessed their quality, and extracted data. Outcomes of interest included cognitive function, change in global function, activities of daily living, functional disability, behavioural function, and adverse events. We used a fixed-effect model for meta-analytic synthesis, and presented results as Peto odds ratios (OR) or weighted mean differences (MD) with 95% confidence intervals. We used Cochrane's original risk of bias tool (RoB 1) to assess the risk of bias in the included studies.

    MAIN RESULTS: We included 21 studies with a total of 10,990 participants. The average age of participants was 74 years, and 37% were male. The studies' durations ranged from eight weeks to two years, with 24 weeks being the most common duration. One newly included study assessed the effects of galantamine at two years, and another newly included study involved participants with severe Alzheimer's disease. Nineteen studies with 10,497 participants contributed data to the meta-analysis. All studies had low to unclear risk of bias for randomisation, allocation concealment, and blinding. We judged four studies to be at high risk of bias due to attrition and two due to selective outcome reporting. Galantamine for dementia due to Alzheimer's disease We summarise only the results for galantamine given at 8 to 12 mg twice daily (total galantamine 16 mg to 24 mg/day), assessed at six months. See the full review for results of other dosing regimens and assessment time points. There is high-certainty evidence that, compared to placebo, galantamine improves: cognitive function, as assessed with the Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-cog) (MD-2.86, 95% CI -3.29 to -2.43; 6 studies, 3049 participants; minimum clinically important effect (MCID) = 2.6- to 4-point change); functional disability, as assessed with the Disability Assessment for Dementia (DAD) scale (MD 2.12, 95% CI 0.75 to 3.49; 3 studies, 1275 participants); and behavioural function, as assessed with the Neuropsychiatric Inventory (NPI) (MD -1.63, 95% CI -3.07 to -0.20; 2 studies, 1043 participants) at six months. Galantamine may improve global function at six months, as assessed with the Clinician's Interview-Based Impression of Change plus Caregiver Input (CIBIC-plus) (OR 1.58, 95% CI 1.36 to 1.84; 6 studies, 3002 participants; low-certainty evidence). Participants who received galantamine were more likely than placebo-treated participants to discontinue prematurely (22.7% versus 17.2%) (OR 1.41, 95% CI 1.19 to 1.68; 6 studies, 3336 participants; high-certainty evidence), and experience nausea (20.9% versus 8.4%) (OR 2.89, 95% CI 2.40 to 3.49; 7 studies, 3616 participants; high-certainty evidence) during the studies. Galantamine reduced death rates at six months: 1.3% of participants in the galantamine groups had died compared to 2.3% in the placebo groups (OR 0.56, 95% CI 0.33 to 0.96; 6 studies, 3493 participants; high-certainty evidence). Galantamine for mild cognitive impairment We summarise results, assessed at two years, from two studies that gave participants galantamine at 8 to 12 mg twice daily (total galantamine 16 mg to 24 mg/day). Compared to placebo, galantamine may not improve cognitive function, as assessed with the expanded ADAS-cog for mild cognitive impairment (MD -0.21, 95% CI -0.78 to 0.37; 2 studies, 1901 participants; low-certainty evidence) or activities of daily living, assessed with the Alzheimer's Disease Cooperative Study - Activities of Daily Living scale for mild cognitive impairment (MD 0.30, 95% CI -0.26 to 0.86; 2 studies, 1901 participants; low-certainty evidence). Participants who received galantamine were probably more likely to discontinue prematurely than placebo-treated participants (40.7% versus 28.6%) (OR 1.71, 95% CI 1.42 to 2.05; 2 studies, 2057 participants) and to experience nausea (29.4% versus 10.7%) (OR 3.49, 95% CI 2.75 to 4.44; 2 studies, 2057 participants), both with moderate-certainty evidence. Galantamine may not reduce death rates at 24 months compared to placebo (0.5% versus 0.1%) (OR 5.03, 95% CI 0.87 to 29.10; 2 studies, 2057 participants; low-certainty evidence). Results from subgroup analysis and meta-regression suggest that an imbalance in discontinuation rates between galantamine and placebo groups, together with the use of the 'last observation carried forward' approach to outcome assessment, may potentially bias cognitive outcomes in favour of galantamine.

    AUTHORS' CONCLUSIONS: Compared to placebo, galantamine (when given at a total dose of 16 mg to 24 mg/day) slows the decline in cognitive function, functional ability, and behaviour at six months in people with dementia due to Alzheimer's disease. Galantamine probably also slows declines in global function at six months. The changes observed in cognition, assessed with the ADAS-cog scale, were clinically meaningful. Gastrointestinal-related adverse events are the primary concerns associated with galantamine use in people with dementia, which may limit its tolerability. Although death rates were generally low, participants in the galantamine groups had a reduced risk of death compared to those in the placebo groups. There is no evidence to support the use of galantamine in people with mild cognitive impairment.
