RESUMEN

ß-thalassemia major is an inherited hemoglobinopathy that requires lifelong red blood cell transfusions and iron chelation therapy to prevent complications due to iron overload. Traditionally, ß-thalassemia has been more common in certain regions of the world such as the Mediterranean, Middle East, and Southeast Asia. However, the prevalence of ß-thalassemia is increasing in other regions, including Northern Europe and North America, primarily due to migration. This review summarizes the available data on the changing incidence and prevalence of ß-thalassemia as well as factors influencing disease frequency. The data suggest that the epidemiology of ß-thalassemia is changing: Migration has increased the prevalence of the disease in regions traditionally believed to have a low prevalence, while, at the same time, prevention and screening programs in endemic regions have reduced the number of affected individuals. Various approaches to prevention and screening have been used. Region-specific prevention and treatment programs, customized to align with local healthcare resources and cultural values, have been effective in identifying patients and carriers and providing information and care. Significant challenges remain in universally implementing these programs.

RESUMEN

Until treatment and vaccine for coronavirus disease-2019 (COVID-19) becomes widely available, other methods of reducing infection rates should be explored. This study used a retrospective, observational analysis of deidentified tests performed at a national clinical laboratory to determine if circulating 25-hydroxyvitamin D (25(OH)D) levels are associated with severe acute respiratory disease coronavirus 2 (SARS-CoV-2) positivity rates. Over 190,000 patients from all 50 states with SARS-CoV-2 results performed mid-March through mid-June, 2020 and matching 25(OH)D results from the preceding 12 months were included. Residential zip code data was required to match with US Census data and perform analyses of race/ethnicity proportions and latitude. A total of 191,779 patients were included (median age, 54 years [interquartile range 40.4-64.7]; 68% female. The SARS-CoV-2 positivity rate was 9.3% (95% C.I. 9.2-9.5%) and the mean seasonally adjusted 25(OH)D was 31.7 (SD 11.7). The SARS-CoV-2 positivity rate was higher in the 39,190 patients with "deficient" 25(OH)D values (<20 ng/mL) (12.5%, 95% C.I. 12.2-12.8%) than in the 27,870 patients with "adequate" values (30-34 ng/mL) (8.1%, 95% C.I. 7.8-8.4%) and the 12,321 patients with values ≥55 ng/mL (5.9%, 95% C.I. 5.5-6.4%). The association between 25(OH)D levels and SARS-CoV-2 positivity was best fitted by the weighted second-order polynomial regression, which indicated strong correlation in the total population (R2 = 0.96) and in analyses stratified by all studied demographic factors. The association between lower SARS-CoV-2 positivity rates and higher circulating 25(OH)D levels remained significant in a multivariable logistic model adjusting for all included demographic factors (adjusted odds ratio 0.984 per ng/mL increment, 95% C.I. 0.983-0.986; p<0.001). SARS-CoV-2 positivity is strongly and inversely associated with circulating 25(OH)D levels, a relationship that persists across latitudes, races/ethnicities, both sexes, and age ranges. Our findings provide impetus to explore the role of vitamin D supplementation in reducing the risk for SARS-CoV-2 infection and COVID-19 disease.

RESUMEN

BACKGROUND: The Lancet Commission on Global Surgery proposed that population access to essential surgical care within 2 h is a core indicator of health system preparedness. Little evidence exists to characterise access to surgical care for island nations, including Vanuatu, a lower middle-income country in the Western Pacific. METHODS: A descriptive, facility-based, survey of surgical inpatients was undertaken over a 6-month period at Northern Provincial Hospital (NPH), Espiritu Santo, Vanuatu. This evaluated demographics, access to surgical care using the 'three delays' framework and clinical outcomes. RESULTS: A total of 121 participants were surveyed (60% of all surgical admissions), of which 31% required emergency surgery. Only 20% of emergency surgical cases accessed care within 2 h. There were no emergency cases from Torba or Malekula. The first delay (delay in seeking care) had the biggest impact on timely access. There was a geographic gradient to access, gender preponderance (males), and a delay in seeking surgical care due to a preference for traditional healers. CONCLUSION: There is urgent need to improve access to surgical care in Vanuatu, particularly for Torba and Malekula catchments. Demographic, geographic, sociocultural, and economic factors impact on timely access to surgical care within the northern regions of Vanuatu and support the notion that addressing access barriers is more complex than ensuring the availability of surgical resources. Future priorities should include efforts to reduce the first delay, address the role of traditional medicine, and review the geographic disparities in access.

RESUMEN

Nusinsersen is now available in Italy for all SMA types. We describe the experience with intrathecal treatment with nusinersen in 50 patients with SMA at the NEMO Center (NEuroMuscular Omniservice Clinical Center) in Milan, a neuromuscular patient-centered clinic hosted within Niguarda Hospital, a National Public General Hospital. Our results indicate that the pathway of care described outweighs the burden due to the repeated intrathecal injections. Irrespective of age and severity, the treatment is feasible, accessible, and replicable provided that there is a multidisciplinary team having experience and training in SMA.

RESUMEN

OBJECTIVE: To determine the effect of clinical, socio-demographic, and contextual characteristics on treatment retention in an opioid treatment program (OTP). METHODS: A retrospective longitudinal review of 851 clients who received methadone at the only state-funded OTP in Spokane County, Washington between 2015 and 2017. A time variable (the number of days in treatment) and a status indicator (to distinguish between clients who dropped out or censored) worked together to define retention in treatment. Our hypothesized covariates included: area deprivation, distance to the OTP, availability of cannabis retail outlets, availability of on-premise and off-premise alcohol outlets, methadone dosage, age, gender, race, and years on treatment. Cox regression within the family of survival analysis was used to model time-to-event data in the presence of censored cases. RESULTS: The median duration of retention was 394 (95%CI = 324-464) days. In the multivariable Cox regression, factors predicting treatment retention were area deprivation (HR = 1.79, 95%CI = 1.02-3.15, p = 0.04), age (HR=0.99, 95%CI=0.98-.99, p = 0.008), dosage of methadone (HR=0.98, 95%CI=0.98-0.98, p < 0.001), and the number of years on treatment (HR=1.12, 95%CI=1.06-1.18, p < 0.001). CONCLUSIONS: The findings of this study showed age and methadone dosage were protective factors and area deprivation and years on treatment were risk factors for treatment retention. After dichotomizing methadone dosage, a unique finding of this study was that higher dosage of methadone did not lead to increasingly smaller HRs for dropping out of treatment. Considering that opioid use disorder is a chronic condition, efforts need to be made to target factors associated with retention.

RESUMEN

The increasing technological effectiveness has undoubtedly produced an improvement in clinical parameters of dialysis patients, but this satisfactory therapeutic result did not follow an adequate improvement in mortality or in the perception of quality of life as per patients. Furthermore, dialysis treatment is often associated with "inapparent charges" that reduce the perception of well-being, independently of clinical changes. Thirty years ago, we carried out a national survey on inapparent charges, which represent frustrating aspects that negatively affect patients' perception of their quality of life. Thirty years later, it seemed important for us to repeat the survey to understand if Italian legislative remodeling have introduced changes in procedures and social aspects of dialysis, as preservation of quality of life is an important aspect of the replacement treatment.

RESUMEN

Schizophrenia risk has been linked to urbanization, but the underlying mechanism remains unknown. Green space is hypothesized to positively influence mental health and might mediate risk of schizophrenia by mitigating noise and particle pollution exposure, stress relief, or other unknown mechanisms. The objectives for this study were to determine if green space are associated with schizophrenia risk, and if different measures of green space associate differently with risk. We used satellite data from the Landsat program to quantify green space in a new data set for Denmark at 30×30m resolution for the years 1985-2013. The effect of green space at different ages and within different distances from each person's place of residence on schizophrenia risk was estimated using Cox regression on a very large longitudinal population-based sample of the Danish population (943,027 persons). Living at the lowest amount of green space was associated with a 1.52-fold increased risk of developing schizophrenia compared to persons living at the highest level of green space. This association remained after adjusting for known risk factors for schizophrenia: urbanization, age, sex, and socioeconomic status. The strongest protective association was observed during the earliest childhood years and closest to place of residence. This is the first nationwide population-based study to demonstrate a protective association between green space during childhood and schizophrenia risk; suggesting limited green space as a novel environmental risk factor for schizophrenia. This study supports findings from other studies highlighting positive effects of exposure to natural environments for human health.

RESUMEN

BACKGROUND: The aim of this study was to investigate the prevalence of epidemiologic and physician-diagnosed pollen-induced AR (PiAR) in the grasslands of northern China and to study the impact of the intensity and time of pollen exposure on PiAR prevalence. METHODS: A multistage, clustered and proportionately stratified random sampling with a field interviewer-administered survey study was performed together with skin prick tests (SPT) and measurements of the daily pollen count. RESULTS: A total of 6043 subjects completed the study, with a proportion of 32.4% epidemiologic AR and 18.5% PiAR. The prevalence was higher in males than females (19.6% vs 17.4%, P = .024), but no difference between the two major residential and ethnic groups (Han and Mongolian) was observed. Subjects from urban areas showed higher prevalence of PiAR than rural areas (23.1% vs 14.0%, P < .001). Most PiAR patients were sensitized to two or more pollens (79.4%) with artemisia, chenopodium, and humulus scandens being the most common pollen types, which were similarly found as the top three sensitizing pollen allergens by SPT. There were significant regional differences in the prevalence of epidemiologic AR (from 18.6% to 52.9%) and PiAR (from 10.5% to 31.4%) among the six areas investigated. PiAR symptoms were positively associated with pollen counts, temperature, and precipitation (P < .05), but negatively with wind speed and pressure P < .05). CONCLUSION: Pollen-induced AR (PiAR) prevalence in the investigated region is extremely high due to high seasonal pollen exposure, which was influenced by local environmental and climate conditions.

RESUMEN

Background: Invasive Mucorales infections (IMI) lead to significant morbidity and mortality in immunocompromised hosts. The role of season and climatic conditions in case clustering of IMI remain poorly understood. Methods: Following detection of a cluster of sinopulmonary IMIs in patients with hematologic malignancies, we reviewed center-based medical records of all patients with IMIs and other invasive fungal infections (IFIs) between January of 2012 and August of 2015 to assess for case clustering in relation to seasonality. Results: A cluster of 7 patients were identified with sinopulmonary IMIs (Rhizopus microsporus/azygosporus, 6; Rhizomucor pusillus, 1) during a 3 month period between June and August of 2014. All patients died or were discharged to hospice. The cluster was managed with institution of standardized posaconazole prophylaxis to high-risk patients and patient use of N-95 masks when outside of protected areas on the inpatient service. Review of an earlier study period identified 11 patients with IMIs of varying species over the preceding 29 months without evidence of clustering. There were 9 total IMIs in the later study period (12 month post-initial cluster) with 5 additional cases in the summer months, again suggesting seasonal clustering. Extensive environmental sampling did not reveal a source of mold. Using local climatological data abstracted from National Centers for Environmental Information the clusters appeared to be associated with high temperatures and low precipitation. Conclusions: Sinopulmonary Mucorales clusters at our center had a seasonal variation which appeared to be related to temperature and precipitation. Given the significant mortality associated with IMIs, local climatic conditions may need to be considered when considering center specific fungal prevention and prophylaxis strategies for high-risk patients.

RESUMEN

Toxoplasmosis, caused by Toxoplasma gondii, has traditionally been considered an important water and foodborne protozoonosis with important public health considerations. Although felids play a well-established role as definitive hosts, canine epidemiological involvement in the parasite's life cycle remains questionable and controversial. The increasing closeness of the human-dog bond, particularly seen in urban settings, has been recognized as a historically unprecedented worldwide movement. Sharing daily lives in the same households, dogs may be exposed to similar associated risks of T. gondii infection as their owners. Thus, epidemiological assessment of the intra-domiciled environment, especially among socio-economically different human populations, may provide novel information regarding the actual role of dogs in animal and human toxoplasmosis. Despite spatial approaches being recently used for other water and foodborne diseases, no study has been conducted on the simultaneous spatial seroprevalence of both human and animal IgG anti-T. gondii antibodies in urban areas of major cities. Accordingly, the aim of the present study was to assess the seroprevalence and associated variables of Toxoplasma infection in owners and their domiciled dogs in Londrina, southern Brazil. Human and canine seroprevalence rates and variables associated with seroprevalence were investigated through representative random sampling among 564 households, which included 597 owners and 729 dogs. Overall, statistically significant differences between the seroprevalence of human and dog anti-T. gondii antibodies were found by Immunofluorescence Antibody Testing in 248/597 (41.54%) owners and 119/729 (16.32%) dogs. Through multiple analysis, significant concomitant variables for seropositivity of household individuals (people and dogs) were determined, including public sewer service, yard cleaning frequency, and having a dirty yard. Although no statistically significant multiple logistic model was observed among owners, univariate analysis detected associations with monthly income, soil contact, and occupation. Among dogs, the absence of other dogs and the absence of a dirty yard were concomitant significantly protective associated factors. Age differences between seropositive and seronegative individuals was significant only for human beings, with the median age of negative individuals significantly higher than positive individuals. Although no spatial clusters were identified for humans or residences, a significant cluster was identified for dogs. In conclusion, characteristics of urban toxoplasmosis may include significantly higher owner seroprevalence than their owned dogs, with canine seroprevalence directly associated with having more dogs and a dirty backyard, and spatial differences in both human and dog exposures. Although not a good indicator for human foodborne diseases, dogs may be a reliable sentinel for environmental infection. Moreover, such a holistic approach may provide crucial information for more focused prevention and monitoring programs, particularly in households with multiple pets and trash-filled backyards.

RESUMEN

BACKGROUND: Associations between environmental factors and spatial disparity of mortality rates of Alzheimer's disease (AD) in the US are not well understood. OBJECTIVE: To find associations between 41 trace elements, four common risk factors, and AD mortality rates in the48 contiguous states. METHODS: Isopleth maps of AD mortality rates of the 48 states and associated factors were examined. Correlations between state average AD mortality rates and concentrations of 41 soil elements, wine consumption, percentage of current smokers, obesity, and diagnosed diabetes of the 48 states between 1999 and 2014 were analyzed. RESULTS: Among 41 elements, soil selenium concentrations have the most significant inverse correlations with AD mortality rates. Rate ratio (RR) of the 6 states with the lowest product of soil selenium and sulfur concentrations is 53% higher than the 6 states with the highest soil selenium sulfur product in the 48 states (RR = 1.53, CI95% 1.51-1.54). Soil tin concentrations have the most significant inverse correlation with AD mortality growth rates between 1999 and 2014, followed by soil sulfur concentrations. Percentages of obesity, diagnosed diabetes, smoking, and wine consumption per capita also correlate significantly with AD mortality growth rates. CONCLUSIONS: High soil selenium and sulfur concentrations and wine consumption are associated with low AD mortality rates. Given that average soil selenium and sulfur concentrations are indicators of their intakes from food, water, and air by people in a region, long-term exposure to high soil selenium and sulfur concentrations might be beneficial to AD mortality rate reduction in a region.

RESUMEN

Iodine nutrition is a result of geological conditions, iodine fortification and monitoring strategies within a country together with the dietary habits of the population. This review summarizes the basis for the current iodine situation in the Scandinavian countries in order to identify gaps in knowledge, determine necessary future steps, highlight landmarks in Scandinavian iodine research and consider ongoing studies in Scandinavian countries with high international impact. Historically, iodine deficiency disorders such as goiter were common in Norway and Sweden, but not in Denmark. Different strategies have been used in Scandinavia to improve iodine nutrition. The major source of iodine is iodized salt in Sweden and from milk and dairy products in Norway. In Denmark, drinking water, milk, dairy products and iodized salt used in commercial production of bread are the important sources of iodine. The current iodine status in Scandinavia is not optimal and action is ongoing to increase iodination in Denmark, where there is mild iodine deficiency in the general population. Data from all three countries indicate insufficient iodine nutrition during pregnancy and there is a need for data from children, adolescents and young women. Monitoring a population's iodine status and dietary iodine sources is necessary to secure iodine nutrition in Scandinavia. Ongoing studies in Scandinavia will contribute significantly to the knowledge about the effects of mild to moderate iodine deficiency.

RESUMEN

Based on the living times, native places and medical works of Xin'an TCM physicians described in the Xin an ming yi kao(Textual Research of Famous Physicians of Xin'an Region), the geographical distribution of ancient TCM physicians was analyzed by using Excel software. It is found that Xin'an medicine was originated from the Eastern Jin Dynasty and highly developed in the Qing Dynasty, and the number of its TCM physicians in the Ming and Qing Dynasties was large than the summation of those from the Eastern Jin Dynasty to the Ming Dynasty. In regard to the district, the distribution of Xin'an TCM physicians was characterized by more in the southeastern and less in the northwestern parts, forming a distribution area concentrated in the three counties of Shexian, Wuyuan and Xiuning. The reasons of such concentration of Xin'an TCM physicians are closely related to the economic growth, the influence of Neo-Confucianism and the density of population.

RESUMEN

We describe the epidemiology, clinical features, and molecular characterization of enterohemorrhagic Escherichia coli (EHEC) infections caused by the singular hybrid pathotype O80:H2, and we examine the influence of antibiotics on Shiga toxin production. In France, during 2005-2014, a total of 54 patients were infected with EHEC O80:H2; 91% had hemolytic uremic syndrome. Two patients had invasive infections, and 2 died. All strains carried stx2 (variants stx2a, 2c, or 2d); the rare intimin gene (eae-ξ); and at least 4 genes characteristic of pS88, a plasmid associated with extraintestinal virulence. Similar strains were found in Spain. All isolates belonged to the same clonal group. At subinhibitory concentrations, azithromycin decreased Shiga toxin production significantly, ciprofloxacin increased it substantially, and ceftriaxone had no major effect. Antibiotic combinations that included azithromycin also were tested. EHEC O80:H2, which can induce hemolytic uremic syndrome complicated by bacteremia, is emerging in France. However, azithromycin might effectively combat these infections.

RESUMEN

Our health depends on where we currently live, as well as on where we have lived in the past and for how long in each place. An individual's place history is particularly relevant in conditions with long latency between exposures and clinical manifestations, as is the case in many types of cancer and chronic conditions. A patient's geographic history should routinely be considered by physicians when diagnosing and treating individual patients. It can provide useful contextual environmental information (and the corresponding health risks) about the patient, and should thus form an essential part of every electronic patient/health record. Medical geology investigations, in their attempt to document the complex relationships between the environment and human health, typically involve a multitude of disciplines and expertise. Arguably, the spatial component is the one factor that ties in all these disciplines together in medical geology studies. In a general sense, epidemiology, statistical genetics, geoscience, geomedical engineering and public and environmental health informatics tend to study data in terms of populations, whereas medicine (including personalised and precision geomedicine, and lifestyle medicine), genetics, genomics, toxicology and biomedical/health informatics more likely work on individuals or some individual mechanism describing disease. This article introduces with examples the core concepts of medical geology and geomedicine. The ultimate goals of prediction, prevention and personalised treatment in the case of geology-dependent disease can only be realised through an intensive multiple-disciplinary approach, where the various relevant disciplines collaborate together and complement each other in additive (multidisciplinary), interactive (interdisciplinary) and holistic (transdisciplinary and cross-disciplinary) manners.

RESUMEN

PURPOSE: Acute dysbarism is a potentially lethal injury associated with environmental medicine. Therefore, prompt treatment, including transportation of victims, is important for the best prognosis. The aim of this study was to examine transportation routes of patients with acute dysbarism for the best prognosis in Korea. METHODS: Geography of South Korea was analyzed using the geographic information system (GIS). The study examined two scenarios using transportation analysis, which relies on a GIS base and pressure variation during air and ground transportation. Given the practical assumptions, we propose some heuristic transportation routes based on the simulation of altitude, transportation time, and availability of related factors. RESULTS: Currently, transportation by ground to the treatment facilities always passes high altitude areas above 152 feet. Also, available helicopters for air transportation could not approach the treatment facilities due to the limitation of flying distance and insufficiency of medical staff and treatment equipment. Altitude variation and delayed time were identified during the period of transportation by ground from Ganneung or Incheon to Tongyoung. Heuristic algorism through the above facts recommends air transport along coasts as the best method for transportation from Ganneung or Incheon to Tongyoung. CONCLUSION: In Korea, transportation by ground was not expected to result in the best prognosis for patients with acute dysbarism. Transportation by air should be considered first as the method of transportation. Also, for the best treatment of patients with acute dysbarism, additional treatment facilities need to be established in the west coast region.

RESUMEN

BACKGROUND: Climate factors and pollen counts may play a role in hay fever. OBJECTIVE: We sought to determine the impact of specific climate factors and pollen counts on the US prevalence of hay fever and statewide variation in prevalence. METHODS: We used a merged analysis of the 2007 National Survey of Children's Health from a representative sample of 91,642 children aged 0 to 17 years and the 2006-2007 National Climate Data Center and Weather Service measurements of relative humidity (%), indoor heating degree days, precipitation, Palmer Hydrological Drought Index, clear sky and issued ultraviolet indices, stratospheric ozone levels, and outdoor air temperature and National Allergy Bureau total pollen counts. Multivariate survey logistic regression models controlled for sex, race/ethnicity, age, household income, and birthplace. RESULTS: The US prevalence of hay fever in childhood was 18.0% (95% CI, 17.7% to 18.2%), with the highest prevalence in southeastern and southern states. Hay fever prevalence was significantly lower with second and third quartile mean annual relative humidity (logistic regression, P ≤ .01 for both), fourth quartile mean annual Palmer Hydrological Drought Index (P = .02), third and fourth quartile mean annual heating degree days (P < .0001 for both), and third and fourth quartile mean annual stratospheric ozone levels but increased with second, third, and fourth quartile mean annual temperature (P ≤ .02 for both), fourth quartile mean annual precipitation (P = .0007), mean total pollen counts (P = .01), and second, third, and fourth quartile issued ultraviolet index (P ≤ .0001 for all). Principal-component analysis was also used to determine the combined effects of correlated climate variables and pollen counts. CONCLUSIONS: This study provides evidence of the influence of climate on the US prevalence of childhood hay fever.

RESUMEN

Radix Angelica sinensis (Danggui, DG), derived from the dry root of Angelicae sinensis, is popularly used for its antioxidant, hematinic and immuno-enhancement. However, DG from different origins possess different quality, and difficult to identity. In this study, we used electronic nose technique to investigate DG from different producing areas for monitoring the correlation of origin and quality. The electronic nose was employed to establish classification model of DG originated from four main producing areas of Gansu, Yunnan, Sichuan and Hubei in China. Principal component analysis (PCA) and discriminant function analysis (DFA) were performed to differentiate DG samples from four main producing areas. The content of phthalides of DG were determined to confirm the quality changes and investigate its correlation with the odor response values by Gas Chromatography-Mass Spectrometer (GC-MS). The results of PCA and DFA analysis showed that the electronic nose could accurately distinguish DG from four main producing areas. The method of electronic nose for identification could be verified by GC-MS technology, and the main ingredient content was consistent with its odor of DG. In conclusion, electronic nose could effectively identify different origins of DG, and could be applied for rapid identification and quality control of genuine Angelica herbs.

RESUMEN

The concept of therapeutic landscapes, as introduced by Gesler, has had a significant impact on what has become a reformed geography (or geographies) of health. Research in this field has developed the number and type of sites that have been characterised as therapeutic landscapes. A wide range of environments have now been explored through the analytical lens of the 'therapeutic landscape'. This research further expands current descriptions of such environments by exploring Edgelands as therapeutic micro landscapes. Edgelands refer to the neglected and routinely ignored interfacial zone between urban and rural that are a routine characteristic of the urban fringe resulting from dynamic cycles of urban development and decay. Using a hybrid method of thematic analysis incorporating both inductive and deductive approaches, this research explores Richard Mabey's seminal work on this topic, The Unofficial Countryside. Previous examinations of the features of therapeutic environments are therefore scrutinised to explore both scale and the possibility of further extending the kind of environments that may be described as therapeutic to include Edgelands. This approach is informed, in part, by principles of mindfulness, a historically Eastern, but increasingly Western approach to exploring oneself and the environment. This research identifies that these overlooked and neglected landscapes are in fact vibrant, resilient and enthralling environments teeming with life, renewal and re-birth. Examination reveals that there are three crucial outcomes of this research. The first relates to the issue of scale. Mabey's book provides evidence of the importance of micro environments in providing a therapeutic environmental focus. Secondly, this research explores the potential of mindfulness as an approach in Geography. Lastly, this research also identifies Edgelands as therapeutic sites and calls for an increased understanding and appreciation of their potential.
