ABSTRACT
BACKGROUND: The global need for palliative care (PC) is increasing, especially as the population ages. The diagnosis of a life-threatening illness triggers numerous decisions by healthcare professionals (HCPs). How these professionals understand and deal with PC influences the quantity and quality of care provided to patients. This systematic review aimed to compare perceptions of PC among HCPs around the world. METHODS: The databases (MEDLINE/PubMed, Embase, LILACS, and EBSCO) were searched systematically. Articles reporting on the perception of HCPs, published between January 2012 and December 2022, were included. Texts that reported the perceptions of family members and patients were excluded to avoid the risk of bias. Those included were organized by country/region and continent for later analysis. RESULTS: Of the 2,063 articles initially retrieved 32 were included and provided relevant information from four continents (America, Asia, Europe, and Oceania). Most of this was done through interviews and questionnaires. All HCPs consulted in the studies recognized the importance of PC. The perception of these professionals was influenced by cultural factors (such as religion), difficulties perceived in each country/region (such as inadequate knowledge, conceptual confusion, etc.), diseases, and the age range of patients served. The acceptance and preparation of professionals to deal with this topic in their routine also influenced their perceptions of HCPs. The limitation of this research is the lack of eligible studies from Africa and the small number of participants in some studies. CONCLUSIONS: It can be concluded that HCPs' perceptions of PC are similar, regardless of their country of origin.

Advancements in medical science and digital access made it easier for individuals to seek appropriate treatment. Despite living in the current information era, the practice of quackery has continued worldwide. The current scoping review was planned to explore different definitions and laws related to quackery, and the acceptance of allied healthcare services in traditional, cultural and legal contexts. The review examined a total of 3,327 published studies and 400 pieces of grey literature, including existing laws, regulatory authority websites, news articles and reports. A total of 56 studies and 21 excerpts were shortlisted for analysis. The definitions of quackery varied significantly across regions, but a general consensus is that unauthorised healthcare practices constitute quackery. Legal perspectives differed worldwide, with Europe, North America and Oceania discouraging allied healthcare services, such as homeopathy, naturopathy and traditional methods, considering them quackery. In contrast, Asian and African regions endorsed allied healthcare and established provider registration and licensing systems.

AIM: We aim to determine the evolutionary origins and population genetics of mallard-like ducks of Oceania, greater Indonesia, and the Philippines. LOCATION: Oceania, greater Indonesia, and the Philippines. TAXON: Mallard (Anas platyrhynchos), Pacific black duck (A. superciliosa spp.), and Philippine duck (A. luzonica) METHODS: Thousands of nuclear ddRAD-seq loci and the mitochondrial DNA control region were assayed across individuals representative of each species' range. We assessed population structure and phylogenetic relationships, as well as estimated demographic histories to reconstruct the biogeographical history of each species. RESULTS: Philippine and Pacific black ducks represent unique genetic lineages that diverged from the mallard 1-2 million years ago. We find no support for the Philippine duck representing a hybrid species as once posited; however, their low levels of genetic diversity requires further attention. We find a lack of substructure among Philippine ducks. However, we found pronounced differentiation between subspecies of Pacific black ducks, especially between A. s. superciliosa from New Zealand and A. s. rogersi from Australia, Papua New Guinea, and Timor-Leste, Indonesia. Anas superciliosa pelewensis gave mixed results; individuals from the Solomon Islands were differentiated from the other subspecies, but those from the island of Aunu'u, American Samoa, were genetically more similar to A. s. rogersi than A. s. pelewensis samples from the Solomon Islands. Finally, we find limited evidence of interspecific gene flow at evolutionary scales, and mallard introgression among contemporary samples. MAIN CONCLUSIONS: Mallard-like ducks radiated across Oceania, greater Indonesia, and the Philippines within the last 2 million years. Only the Pacific black duck showed unique sub-structuring that largely followed known sub-species ranges, except for A. s. pelewensis. We posit that the high interrelatedness among Solomon Island samples suggests that their genetic distinctiveness may simply be the result of high levels of genetic drift. In contrast, we conclude that mainland Australian Pacific black ducks were the most likely source for the recent colonization of American Samoa. As a result, our findings suggest that either the A. s. pelewensis subspecies designations and/or its geographical range may require re-evaluation. Continued re-evaluation of evolutionary and taxonomic relationships is necessary when attempting to reconstruct and understand biogeographical histories, with important implications towards any attempts to implement conservation strategies.

AIM: We aimed to assess the global implications of low physical activity (LPA) on type 2 diabetes mellitus (T2DM) by utilizing data from the Global Burden of Disease (GBD) 2019. METHODS: The analysis was conducted by examining the age-standardized disability-adjusted life years (DALYs) rates over a 30-year period. To assess the trends, we utilized estimated annual percentage changes (EAPCs). RESULTS: The study revealed a notable increase in the burden of DALYs attributable to T2DM resulting from LPA, with an EAPC of 0.84 (95% confidence interval 0.78-0.89). Among the regions examined, Oceania showed the highest burden, whereas Eastern Europe exhibited the lowest burden. Specifically, within the Central Asia region, a considerable increase in T2DM-LPA DALYs was observed, with an EAPC of 3.18 (95% confidence interval 3.01-3.36). The burden associated with T2DM-LPA DALYs was found to be similar between genders and increased across all age groups, peaking in the 80-84 years. Furthermore, there was a clear association between the socio-demographic index (SDI) and the age-standardized DALYs rate. Regions categorized as low-middle and middle SDI experienced a substantial rise in burden. CONCLUSION: This study highlights a substantial increase in the T2DM-LPA DALYs in low-middle and middle SDI regions, as well as among individuals aged 80-84 years. These findings emphasize the importance of implementing comprehensive global health interventions that promote physical activity, particularly targeting high-risk populations and regions.

Background: As the health status of a population is influenced by a variety of health determinants, we sought to assess their impact on health outcomes, both at the global and regional levels. Methods: This ecological study encompassed all 194 member countries of the World Health Organization (WHO) from 2000 to 2018. We first identified all health determinants and then retrieved the related data from various global databases. We additionally considered three indicators - disability-adjusted life years (DALYs), years of life lost (YLL), and years lived with disability (YLD) - in evaluating health outcomes; we extracted their data from the Global Burden of Disease (GBD) 2019 study. We then applied econometric analyses using a multilevel mixed-effects linear regression model. Results: The analysis using the DALY indicator showed that the variables of sexually transmitted infections, injuries prevalence, and urbanisation had the highest effect size or regression coefficients (ß) for health outcomes. The variables of sexually transmitted infection (ß = 0.75, P < 0.001) in the African region; drinking water (ß = -0.60, P < 0.001), alcohol use (ß = 0.20, P < 0.001), and drug use (ß = 0.05, P = 0.036) in the Americas region; urbanisation (ß = -0.34, P < 0.001) in the Eastern Mediterranean region; current health expenditure (ß = -0.21, P < 0.001) in the Europe region; injuries (ß = 0.65, P < 0.001), air pollution (ß = 0.29, P < 0.001), and obesity (ß = 0.92, P < 0.001) in the South-East Asia region; and gross domestic product (ß = -0.25, P < 0.001), education (ß = -0.90, P < 0.001), and smoking (ß = 0.28, P < 0.001) in the Western Pacific region had the most significant role in explaining global health outcomes. Except for the drug use variable in regional findings, the role of other variables in explaining the YLL indicator was greater than that of the YLD indicator. Conclusions: To address global health disparities and optimise resource allocation, global and interregional policymakers should focus on determinants that had the highest ß with health outcomes in each region compared to other regions. These determinants likely have a higher marginal health product, and investing in them is likely to be more cost-effective.

People with schizophrenia die prematurely, yet regional differences are unclear. PRISMA 2020-compliant systematic review/random-effects meta-analysis of cohort studies assessing mortality relative risk (RR) versus any control group, and moderators, in people with ICD/DSM-defined schizophrenia, comparing countries and continents. We conducted subgroup, meta-regression analyses, and quality assessment. The primary outcome was all-cause mortality. Secondary outcomes were suicide-, /natural-cause- and other-cause-related mortality. We included 135 studies from Europe (n = 70), North-America (n = 29), Asia (n = 33), Oceania (n = 2), Africa (n = 1). In incident plus prevalent schizophrenia, differences across continents emerged for all-cause mortality (highest in Africa, RR=5.98, 95 %C.I.=4.09-8.74, k = 1, lowest in North-America, RR=2.14, 95 %C.I.=1.92-2.38, k = 16), suicide (highest in Oceania, RR=13.5, 95 %C.I.=10.08-18.07, k = 1, lowest in North-America, RR=4.4, 95 %C.I.=4.07-4.76, k = 6), but not for natural-cause mortality. Europe had the largest association between antipsychotics and lower all-cause mortality/suicide (Asia had the smallest or no significant association, respectively), without differences for natural-cause mortality. Higher country socio-demographic index significantly moderated larger suicide-related and smaller natural-cause-related mortality risk in incident schizophrenia, with reversed associations in prevalent schizophrenia. Antipsychotics had a larger/smaller protective association in incident/prevalent schizophrenia regarding all-cause mortality, and smaller protective association for suicide-related mortality in prevalent schizophrenia. Additional regional differences emerged in incident schizophrenia, across countries, and secondary outcomes. Significant regional differences emerged for all-cause, cause-specific and suicide-related mortality. Natural-cause death was homogeneously increased globally. Moderators differed across countries. Global initiatives are needed to improve physical health in people with schizophrenia, local studies to identify actionable moderators.

OBJECTIVES: To calculate the case fatality rates (CFR) of COVID-19 during epidemic periods of different variants of concern (VOC) by continents. METHODS: We systematically searched five authoritative databases (Web of Science, PubMed, Embase, Cochrane Library, and MedRxiv) for epidemiological studies on the CFR of COVID-19 published between January 1, 2020, and March 31, 2023. After identifying the epidemic trends of variants, we used a random-effects model to calculate the pooled CFRs during periods of different VOCs. This meta-analysis was conducted following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and registered with PROSPERO (CRD42023431572). RESULTS: There were variations in the CFRs among different variants of COVID-19 (Alpha: 2.62%, Beta: 4.19%, Gamma: 3.60%, Delta: 2.01%, Omicron: 0.70%), and disparities in CFRs also existed among continents. On the whole, the CFRs of COVID-19 in Europe and Oceania were slightly lower than in other continents. There was a statistically significant association between the variant, HDI value, age distribution, coverage of full vaccination of cases, and the CFR. CONCLUSIONS: The CFRs of COVID-19 varied across the epidemic periods of different VOCs, and disparities existed among continents. The CFR value reflected combined effects of various factors within a certain context. Caution should be exercised when comparing CFRs due to disparities in testing capabilities and age distribution among countries, etc.

Abstract: We aimed to investigate some of the medical ethics issues that characterize the COVID-19 vaccination phase in pregnancy and breast-feeding. A literature search was conducted using PubMed, Scopus, Web of Science, focusing mainly on the countries of East Asia and Oceania. Vaccination during pregnancy and breastfeeding appears to help protect babies from COVID-19 by enabling antibodies to pass from mother to baby. However, individual countries of the same continent may adopt conflicting policy positions. Not only that, indications on the type of vaccine sometimes vary, depending on whether a woman is pregnant or breastfeeding. In this review we have taken into considerationp the policy positions on pregnancy and lactation by country and type of Covid-19 vaccine in East Asia and Oceania. Ten out of the 18 countries considered (representing more than two thirds of the population of East Asia and Oceania) provide different vaccine indications for pregnant and breastfeeding women. Can this diversity of recommendations be seen as a form of optimal protection for women in these categories, or does it suggest that some countries have taken a defensive position to avoid compensation claims in the event of complications? Is it ethically correct to leave questions concerning informed consent open? Misin-formation during a health crisis leaves people without protection and with increased vaccine hesitancy, especially for vulnerable populations in hard-to-reach areas of East Asia and Oceania.

PURPOSE: Human papillomavirus (HPV) is the most commonly transmitted sexually transmitted infection. HPV infections have been on the rise among males, especially in the form of oropharyngeal cancer. Despite this, there is a gap in healthcare guidelines to increase HPV vaccine administration among males. In this study, we focus on the Indigenous population of North America and Oceania to determine existing barriers resulting in low HPV vaccination rates among the population. METHOD: We surveyed peer-reviewed literature on the awareness of HPV infection among Indigenous males in North America and Oceania. Using keywords HPV plus male, men or boy, and ethnical filters such as Indigenous, Aboriginal or First Nations, we retrieved 54 articles based on titles, of which 15 were included after reading the abstracts. RESULTS: Reported HPV awareness was generally low in Indigenous males in North America, with no peer-reviewed data from Oceania. The lower understanding by males compared to females was largely attributable to misconceptions about HPV-related diseases, their transmission, and prevention. Lack of awareness and concern toward the risk of contracting HPV infection in Indigenous males suggests an impediment in disseminating health information about this cancer-causing virus. CONCLUSION: Culturally sensitive education, with emphasis on Indigenous males, is needed to improve this group's HPV knowledge. Researchers should also engage meaningfully with Indigenous communities by building rapport to achieve a positive change in attitude.

BACKGROUND: Oceania is a continent, covering more than 8 million km2, with a population of more than 44 million people. In different countries landing in Oceania, various prevalence of MS has been reported, so we designed this systematic review and meta-analysis to estimate the pooled prevalence of MS in Oceania. METHODS: We systematically searched PubMed, Scopus, EMBASE, Web of Science, and Google Scholar. We also searched references of included studies, and conference abstracts. The search was done on January 1, 2023, by two independent researchers. We extracted the name of the first author, country, publication year, prevalence period, number of study participants, total female and male population, disease duration, type of MS, mean duration of the disease, mean age at disease onset, mean Expanded Disability Status Scale (EDSS), and total female and male patients with MS. RESULTS: A literature search revealed 81,044 records; after deleting duplicates, 38,260 records remained. One hundred and six full texts were evaluated, and finally, seventeen studies remained for systematic review. Most studies were done in Newcastle; eight studies were done in 1961, 8 in 1981, 2 in 1996, and 2 in 2001. In all other years, only one study was done. The pooled prevalence of MS in 1961 in Oceania was estimated as 19.85/100,000 (I2=70.3%, p=0.001). The pooled prevalence of MS in 1981 in Oceania was estimated as 39.07/100,000 (I2 =88%, p=0.001). CONCLUSIONS: The result of this systematic review and meta-analysis shows that the prevalence of MS has increased dramatically during the timespan in Oceania.

Ancient DNA (aDNA) has added a wealth of information about our species' history, including insights on genetic origins, migrations and gene flow, genetic admixture, and health and disease. Much early work has focused on continental-level questions, leaving many regional questions, especially those relevant to the Global South, comparatively underexplored. A few success stories of aDNA studies from smaller laboratories involve more local aspects of human histories and health in the Americas, Africa, Asia, and Oceania. In this Review, we cover some of these contributions by synthesizing finer-scale questions of importance to the archaeogenetics field, as well as to Indigenous and Descendant communities. We further highlight the potential of aDNA to uncover past histories in regions where colonialism has neglected the oral histories of oppressed peoples.

BACKGROUND AND PURPOSE: Antibiotic-loaded bone cement (ALBC) and systemic antibiotic prophylaxis (SAP) have been used to reduce periprosthetic joint infection (PJI) rates. We investigated the use of ALBC and SAP in primary total knee arthroplasty (TKA). PATIENTS AND METHODS: This observational study is based on 2,971,357 primary TKAs reported in 2010-2020 to national/regional joint arthroplasty registries in Australia, Denmark, Finland, Germany, Italy, the Netherlands, New Zealand, Norway, Romania, South Africa, Sweden, Switzerland, the UK, and the USA. Aggregate-level data on trends and types of bone cement, antibiotic agents, and doses and duration of SAP used was extracted from participating registries. RESULTS: ALBC was used in 77% of the TKAs with variation ranging from 100% in Norway to 31% in the USA. Palacos R+G was the most common (62%) ALBC type used. The primary antibiotic used in ALBC was gentamicin (94%). Use of ALBC in combination with SAP was common practice (77%). Cefazolin was the most common (32%) SAP agent. The doses and duration of SAP used varied from one single preoperative dosage as standard practice in Bolzano, Italy (98%) to 1-day 4 doses in Norway (83% of the 40,709 TKAs reported to the Norwegian arthroplasty register). CONCLUSION: The proportion of ALBC usage in primary TKA varies internationally, with gentamicin being the most common antibiotic. ALBC in combination with SAP was common practice, with cefazolin the most common SAP agent. The type of ALBC and type, dose, and duration of SAP varied among participating countries.

As the first in-person Asia Oceania Human Proteomics Organization (AOHUPO) congress since 2018, the 11th AOHUPO congress was an opportune time for the research community to reconnect and to renew friendships after the long period of restricted travel due to the global pandemic. Moreover, this congress was a great opportunity for the many AO regional proteomics and mass spectrometry scientists to meet in Singapore to exchange ideas and to present their latest findings. Cohosted by the Singapore Society for Mass Spectrometry and the Malaysian Proteomics Society and held in conjunction with the seventh Asia Oceania Agricultural Proteomics Organization Congress and Singapore Society for Mass Spectrometry 2023, the meeting featured both human and agricultural proteomics. Over five hundred scientists from the AO region converged on the MAX Atria @ Singapore EXPO, Changi, Singapore from May 8 to 10 for the main congress. The diverse program was made up of 64 invited speakers and panellists for seven plenary lectures, 27 concurrent symposia, precongress and postcongress workshops, and 174 poster presentations. The AOHUPO society were able to celebrate not only their 20th anniversary but also the outstanding academic research from biological and agricultural proteomics and related 'omics fields being conducted across the Asia-Oceania region.

Objective: Cancer is a major health problem worldwide including Asian-Pacific region. The region hosts over 4.5 billion people, over 60% of the world population and very divergent socioeconomically. The major cancers in the region in male include lung, stomach, liver, colorectal and esophagus and in female breast, lung, cervix, colorectal, and stomach. Over 60% of cancer patients need radiotherapy alone or in combination with surgery and/or chemotherapy, and therefore, radiotherapy is the main and essential modality of cancer treatment. Radiation oncology medical physicists play a pivotal role in efficient implementation of radiotherapy. This study was aimed to assess the status of cancer treatment by radiotherapy and the requirement of radiation oncology medical physicists in the region. Materials and Methods: To access the status and requirement of radiotherapy machines, availability of radiation oncology physicists in the region of Asia Oceania Federation of Organizations for Medical Physics (AFOMP), we have carried out a survey by sending questioners to AFOMP National Medical Physics Organizations (NMO). We received response from 21 countries, 100% response, regarding availability of teletherapy units, number of medical physicists working in radiotherapy and related information. Using GLOBOCAN cancer incidence data and considering 62.5% of cancer patients need radiotherapy treatment and up to 500 cancer patients can be treated in a year on one teletherapy machine, the gap between the available and required teletherapy machine to treat all the cancer patients requiring radiotherapy is estimated. Further, we estimated the gap between radiotherapy medical physicists available and required as per International Atomic Energy Agency and European Society for Therapeutic Radiology and Oncology guidelines. Results: It was observed that availability of teletherapy machines in AFOMP region is 0.21-14.0 teletherapy machine/million population and radiotherapy medical physicist are 0.82-2.43/teletherapy unit.

OBJECTIVES: Pediatric inflammatory bowel diseases (IBDs) are chronic, idiopathic illnesses of the digestive tract, which can impact adversely on children's quality of life and burden health systems. International studies have shown these diseases are increasing. The aim was to describe pediatric IBD epidemiology across Oceania by conducting a systematic review and meta-analysis of incidence and prevalence. METHODS: Medline, EMBASE and Web of Science databases were searched in October 2022 for studies reporting rates of IBD, Crohn disease (CD), or ulcerative colitis (UC) in children (≤19 years). Several data collection methodologies were included and pooled estimates of incidence and prevalence were calculated using a random effects model with I2 measures of heterogeneity. RESULTS: Nineteen articles provided 15 incidence and 7 prevalence studies. Fourteen studies were from Australia, 8 studies from New Zealand, and no studies were found from the Pacific Islands. Study dates ranged from 1950 to 2020 with 11 studies using population-based designs. Pooled estimates for annual incidence were IBD 4.1 (3.4-4.8, I2 = 98.7), CD 2.3 (1.9-2.7, I2 = 98.6), and UC 0.9 (0.6-1.1, I2 = 96.8) per 100,000 person-years. Prevalence rates were IBD 36.0 (23.5-48.5, I2 = 98.4), CD 23.2 (6.6-39.8, I2 = 97.8), and UC 7.6 (2.7-12.5, I2 = 99.6) per 100,000 persons. CONCLUSIONS: Pediatric IBD is prevalent in Oceania with high incidence rates, particularly for CD. Low rates of IBD were observed in indigenous Australian, Maori, and New Zealand Pacific children and there were no studies from the Pacific Islands highlighting this as an area in need of further research.

BACKGROUND: Criticisms have emerged that cancer medicines offer modest benefits at increasingly high prices. Reimbursement decisions made by health technology assessment (HTA) agencies have become a complex endeavour for cancer medicines. Most high-income countries (HICs) use HTA criteria to identify high-value medicines for reimbursement under public drug coverage plans. We compared HTA criteria specific for cancer medicines in economically similar HICs, to understand how these criteria contribute to reimbursement decisions. METHODS: We did an international, cross-sectional analysis in collaboration with author investigators across eight HICs, from the Group of Seven (known as G7; Canada, England, France, Germany, Italy, and Japan) and Oceania (Australia and New Zealand). Publicly available data from HTA agency reports and official documentation were extracted and analysed between Aug 15, 2021, and July 31, 2022. We collected data pertaining to the decision-making criteria used by the national HTA agency; HTA reimbursement status for 34 medicine-indication pairs corresponding to 15 unique US top-selling cancer medicines; and HTA reimbursement status for 18 cancer medicine-indication pairs (13 unique medicines) with minimal clinical benefit (score of 1 on the European Society of Medical Oncology Magnitude of Clinical Benefit Scale). Descriptive statistics were used to compare HTA decision criteria and drug reimbursement recommendations (or for Germany and Japan, final reimbursement status) across the eight countries. FINDINGS: Therapeutic impact related to clinical outcomes of the new medicine was a uniform criterion across the eight countries, whereas quality of evidence (under the remit of therapeutic impact assessment) and equity were infrequently cited criteria. Only the German HTA agency mandated that surrogate endpoints be validated in therapeutic impact assessment. All countries except Germany included formal cost-effectiveness analyses within HTA reports. England and Japan were the only countries that specified a cost-effectiveness threshold. Of the 34 medicine-indication pairs corresponding to US top-selling cancer medicines, Germany reimbursed the maximum (34 [100%]), followed by Italy (32 [94%] recommended for reimbursement), Japan (28 [82%] reimbursed), Australia, Canada, England, and France (27 [79%] recommended for reimbursement), and New Zealand (12 [35%] recommended for reimbursement). Of the 18 cancer medicine-indication pairs with marginal clinical benefit, Germany reimbursed 15 (83%) and Japan reimbursed 12 (67%). France recommended nine (50%) for reimbursement, followed by Italy (seven [39%]), Canada (five [28%]), and Australia and England (three [17%] each). New Zealand did not recommend any medicine-indications with marginal clinical benefit for reimbursement. Considering the overall cumulative proportion across the eight countries, 58 (21%) of 272 indications for the US top-selling medicines and 90 (63%) of 144 marginally beneficial medicine-indications were not recommended for reimbursement or reimbursed. INTERPRETATION: Our findings indicate discordance in public reimbursement decisions across economically similar countries, despite overlapping HTA decision criteria. This suggests a need for improved transparency around the nuances of the criteria to ensure improved access to high-value cancer medicines, and deprioritisation of low-value cancer medicines. Health systems have opportunities to improve their HTA decision-making processes by learning from the systems in other countries. FUNDING: None.

BACKGROUND AND OBJECTIVES: Amyotrophic lateral sclerosis (ALS) is a rare neurodegenerative disorder affecting upper and lower motor neurons. Due to its rarity and rapidly progressive nature, studying the epidemiology of ALS is challenging, and a comprehensive picture of the global burden of this disease is lacking. The objective of this systematic review was to describe the global incidence and prevalence of ALS. METHODS: We searched MEDLINE, Embase, Global Health, PsycInfo, Cochrane Library, and CINAHL to identify articles published between January 1, 2010, and May 6, 2021. Studies that were population based and reported estimates of prevalence, incidence, and/or mortality of ALS were eligible for inclusion. This study focuses on the incidence and prevalence. Quality assessment was performed using a tool developed to evaluate methodology relevant to prevalence and incidence studies. This review was registered with PROSPERO, CRD42021250559. RESULTS: This search generated 6,238 articles, of which 140 were selected for data extraction and quality assessment. Of these, 85 articles reported on the incidence and 61 on the prevalence of ALS. Incidence ranged from 0.26 per 100,000 person-years in Ecuador to 23.46 per 100,000 person-years in Japan. Point prevalence ranged from 1.57 per 100,000 in Iran to 11.80 per 100,000 in the United States. Many articles identified cases with ALS from multiple data sources. DISCUSSION: There is variation in reported incidence and prevalence estimates of ALS across the world. While registries are an important and powerful tool to quantify disease burden, such resources are not available everywhere. This results in gaps in reporting of the global epidemiology of ALS, as highlighted by the degree of variation (and quality) in estimates of incidence and prevalence reported in this review.
