RESUMEN
Diabetic retinopathy (DR), which can cause vision loss, may progress faster with poor glycemic control and oxidative stress. This study aims to examine how dietary patterns and glycemic control biomarkers relate to retinopathy risk in type 2 diabetes patients. In this study, we enrolled diabetic patients with retinopathy (DR) (n = 136) and without retinopathy (no DR) (n = 466) from a cohort of participants in the "Blood Pressure Control to Reduce the Risk of Type 2 Diabetic Nephropathy Study". Hemoglobin A1c (HbA1c) and malondialdehyde were defined as elevated when their levels reached ≥8.5% and ≥2/3 (16.2 µm), respectively. Dietary data were collected by a food frequency questionnaire. Dietary patterns were identified by factor analysis. Elevated HbA1c was significantly correlated with increased risk of DR (OR: 2.12, 95% CI: 1.14-3.93, p = 0.017). In subjects with a high animal protein and processed food dietary pattern (≥highest tertile score) or a low vegetable intake pattern (Asunto(s)

RESUMEN
Objective To analyze the current situation of dietary diversity and caregiver self-efficacy for complementary feeding among infants and young children aged 6 to 23 months in rural Nanchong city,Sichuan province,and to explore the relationship between dietary diversity and caregiver self-efficacy. Methods Multi-stage randomized cluster sampling method was used to select infants and young children aged 6 to 23 months and their caregivers in rural areas of Nanchong city,Sichuan province as the subjects.A structured questionnaire was designed to collect the basic information of the subjects,dietary diversity,and caregiver self-efficacy for complementary feeding.Multivariate Logistic regression was adopted to analyze the relationship between the dietary diversity and caregiver self-efficacy for complementary feeding of infants and young children. Results A total of 770 pairs of infants and young children and their caregivers were included.The minimum pass rate of dietary diversity was 61.56%(474/770) for all the infants and young children and 45.00%(108/240),69.16%(287/415),and 68.70%(79/115) for the infants and young children aged 6 to 11,12 to 17,and 18 to 23 months,respectively.The results of regression analysis showed that the caregiver self-efficacy of complementary feeding was a contributing factor for qualified dietary diversity of infants and young children in the case of other confounders being controlled(OR=1.42,95%CI=1.17-1.73,P<0.001). Conclusion The dietary diversity for infants and young children in rural Nanchong city,Sichuan province needs to be improved,and caregivers with higher self-efficacy of complementary feeding are more likely to provide diversified complementary feeding for infants and young children.

Objective To understand the current situation and explore the influencing factors of delay in seeking medical treatment for common symptoms of residents in the rural areas of Sichuan province. Methods In July 2019,multi-stage random sampling was carried out in Zigong city,Sichuan province,and the data were collected by face-to-face questionnaire interview.The residents who had lived at hometown for more than half a year in the past year and had seen a doctor in the most recent month were surveyed.Logistic regression was adopted to predict the influencing factors of delay in seeking medical treatment. Results A total of 342 subjects were enrolled,and the incidence of delay in seeking medical treatment was 13.45%(46/342).Compared with the young and middle-aged(<65 years)people,the elderly(≥65 years)people were more likely to have delay in seeking medical treatment (OR=2.187,95%CI=1.074-4.457,P=0.031).The rural residents who gave higher score of the overall quality of township health centers were less likely to have delay in seeking medical treatment (OR=0.854,95%CI=0.735-0.992,P=0.039). Conclusions The occurrence of delay in seeking medical treatment for common symptoms of rural residents in Sichuan province is low.Age and the overall quality evaluation of township health centers affect the occurrence of delay in medical treatment among the rural residents in Sichuan province.Efforts should be made to improve the awareness of disease prevention among the elderly in rural areas.The investment in health resources in township health centers should be increased to strengthen the introduction and training of talents.These measures can improve the health services in township health centers,guide residents to make timely use of health resources,and reduce the occurrence of delay in seeking medical treatment.

Objective: To evaluate the status of information communication concerning micronutrient powders (MNP), or yingyangbao in Pinyin, the Chinese Romanization system, in areas covered by the Child Nutrition Improvement Project in a province in southwest China, and to investigate the effect of different communication channels and message communicated on the feeding behaviors of different generations of caregivers. Methods: In October 2019, 6 counties, including two counties with predominantly Han population, two counties with substantial Tibetan population, and two counties with substantial Yi population, were selected from a province in southwest China through multistage random cluster sampling. A total of 816 pairs of babies and their caregivers from 108 villages in 36 townships were enrolled for the study. The age of the babies ranged between 6 months to 24 months. A structured questionnaire concerning the demographic data of the babies and their caregivers, the communication channel of information on MNP and the message communicated, and the caregivers' MNP feeding behaviors was designed to collect data through face-to-face interviews. Logistic regression was done to analyze the effect of MNP information communication on the feeding behaviors of caregivers from different generations. Results: Caregivers acquired information on MNP from village and township physicians (85.66%), surrounding populations (15.81%), and brochures and mass media (4.78%). The messages they received included the free availability of MNP (37.50%), feeding methods (49.26%), and the benefits of giving babies MNP (57.84%). Among the caregivers, 89.95% knew about the availability of MNP, 69.73% were aware of the benefits, and 84.07% actually received MNP. The correct feeding rate was 68.26% and the total effective feeding rate was 49.14%. The effective feeding rate of caregivers of the grandparents' generation (59.07%) was higher than that of the caregivers of the parents' generation (45.08%) ( P<0.05). Logistic regression analysis suggested that, for caregivers of the parents' generation, information communication channel of village and township physicians (odds ratio [ OR]=2.20, 95% confidence interval [ CI]: 1.13-4.31) and communication messages on feeding methods ( OR=1.80, 95% CI: 1.19-2.73) and benefits of MNP ( OR=2.40, 95% CI: 1.61-3.57) facilitated their effective feeding behavior, while communication message concerning the free availability of MNP ( OR=0.58, 95% CI: 0.38-0.87) inhibited their effective feeding behavior. For caregivers of the grandparents' generation, information communication channel of village and township physicians ( OR=2.95, 95% CI: 1.12-7.76) and communication messages on the feeding methods ( OR=2.86, 95% CI: 1.34-6.09) were facilitating factors of their effective feeding behaviors. Conclusion: The main channel of MNP information delivered to caregivers from the areas covered by the study was face-to-face explanation by doctors. The message communicated mainly involved three aspects--the administration method, the benefits and free availability of MNP. The channel and message of MNP information communnication had different effects on the feeding behaviors of caregivers of the parents' and grandparents' generations. Future research should focus on developing targeted information communication strategies according to the characteristics of populations from different generations, so as to improve the caregivers' feeding behavior.

Objective We used standardized patients to evaluate the accuracy and explore the influencing factors of the diagnosis of unstable angina pectoris and type 2 diabetes by primary healthcare providers in Sichuan rural areas,aiming to provide a scientific basis for improving the diagnosis accuracy of primary healthcare providers for the two chronic diseases. Methods A multi-stage stratified random cluster sampling method was adopted to select 100 villages from 50 townships in 5 districts/counties in Zigong city,Sichuan province. General and internal medicine practioners who were on duty on the survey day were enrolled in the survey.Two rounds of data collection were conducted.In the first round,the basic information of providers from township health centers and village clinics was collected.One month after the the first survey,standardized patients were used to collect the information related to the diagnosis of unstable angina pectoris and type 2 diabetes by rural primary providers.Logistic regression was carried out to analyze the factors influencing the diagnosis accuracy. Results A total of 172 rural primary healthcare providers were enrolled in the survey,who completed 186 standardized patient visits and showed the correct diagnosis rate of 48.39%.Specifically,the correct diagnosis rates of unstable angina pectoris and type 2 diabetes were 18.68%(17/91) and 76.84%(73/95),respectively.The providers with medical practitioner qualifications were more likely to make correct diagnosis(OR=4.857,95%CI=1.076-21.933, P=0.040).The providers who involved more necessary consultation and examination items in the diagnosis process had higher probability of correct diagnosis(OR=1.627,95%CI=1.065-2.485, P=0.024).Additionally,the providers were more likely to make a correct diagnosis for type 2 diabetes than for unstable angina pectoris(OR=6.306,95%CI=3.611-11.013, P<0.001). Conclusions The overall diagnosis accuracy of unstable angina pectoris and type 2 diabetes was relatively low among primary healthcare providers in Sichuan rural areas.The training of diagnosis process can be taken as a key for improving providers' practice ability so as to increase the diagnosis accuracy of chronic diseases.

Objective To understand the growth and dietary diversity status of children in multi-ethnic areas of Sichuan province,and to explore the associations of dietary diversity with growth and development indicators. Methods Children of 18-36 months old and their primary caregivers were selected with multi-stage cluster random sampling method from rural areas of Han,Tibetan,and Yi ethnic groups in Sichuan province. The sociodemographic information of children and their caregivers was collected using self-designed questionnaire.The dietary diversity score(DDS)was calculated according to the criteria in the Guidelines for Measuring Household and Individual Dietary Diversity released by the Food and Agriculture Organization of the United Nations.The body height(length)and body weight of each child were measured by standard equipment for anthropological measurement,and the height for age Z score(HAZ),weight for age Z score(WAZ),and weight for height Z score(WHZ) were calculated.Multivariate linear regression was performed to analyze the relationship between dietary diversity and growth indicators of children. Results A total of 1092 children were enrolled in this study,and the prevalence of stunting(HAZ<-2),underweight(WAZ<-2),and wasting(WHZ<-2)was 21.1%,4.9%,and 2.5%,respectively.The children had the mean DDS of 4.8±1.7,and 45.3% of children had poor dietary diversity(DDS≤4).The children of Han ethnic group(5.8±1.4)had higher DDS than those of Tibetan ethnic group(4.9±1.6)and Yi ethnic group(3.9±1.6)(P<0.001).The results of multivariate linear regression indicated that DDS was positively correlated with HAZ(ß=0.206,95%CI=0.158-0.254,P<0.001)after adjustment of sex,age,birth weight,preterm birth,and parental body height.After further adjustment of family fixed assets,ethnic group,caregiver's type,and caregiver's education background,the correlation between DDS and HAZ remained significant(ß=0.077,95%CI=0.026-0.128, P=0.003). Conclusions The children in the multi-ethnic rural areas of Sichuan province showed troublesome growth and development status and low dietary diversity,which were conspicuously different between ethnic groups,especially in the rural areas of Yi ethnic group.The dietary diversity was positively associated with HAZ.It is recommended to carry out nutrition and health education according to the local dietary characteristics and thus improve the growth and development of children in multi-ethnic rural areas in Sichuan.

OBJECTIVE: Although the provision of nutrition helps minimize adverse outcomes in most patients in intensive care units (ICUs), little is known about the relative effect of energy and protein delivered on mortality in ICU patients with different ranges of body mass index (BMI). The aim of this study was to examine the relationships between adequacy of dietary energy and protein intakes separately and simultaneously, and short-term mortality in medical ICU patients across four BMI categories. METHODS: We enrolled 1693 patients admitted to a medical center ICU in Taiwan during the period of 2005 to 2011, subcategorizing them by BMI levels: <18.5(n = 418), 18.5-24.9 (n = 889), 25-29.9 (n = 289), and ≥30 kg/m2 (n = 97). Dietary energy and protein intake (DEI and DPI) were defined by the percent of prescribed dosages that each patient actually received: highly adequate (>80%), moderately adequate (60-80%), and inadequate (<60%), during the first 10 d in the ICU. RESULTS: Mean DEI was 1237 kcal/d and DPI 47 g protein/d. Analyzed separately in our multiple regression models, moderately and highly adequate DEI (Ptrends = 0.003-0.026) and DPI (Ptrends = 0.001-0.004) were both significantly correlated with reduced mortality in patients with BMI <18.5, 18.5-24.9, and 25-29.9 kg/m2 but not in those with BMI levels ≥30 kg/m2. With DEI and DPI analyzed simultaneously, only APACHE II scores and DPI levels remained significantly related to reduced mortality in patients with BMI <30 kg/m2. CONCLUSION: Although the adequacy of delivery of prescribed DEI or DPI dosages appeared to be important for reduced risks for mortality in ICU patients with BMI <30 kg/m2 when analyzed separately, DPI had a stronger effect on decreases in ICU mortality when the two were analyzed simultaneously. Further investigation may be needed to study the role of increased protein in improving clinical outcomes.

BACKGROUND: The coronavirus disease (COVID-19) has been identified as the cause of an outbreak of respiratory illness in Wuhan, Hubei Province, China beginning in December 2019. As of 31 January 2020, this epidemic had spread to 19 countries with 11 791 confirmed cases, including 213 deaths. The World Health Organization has declared it a Public Health Emergency of International Concern. METHODS: A scoping review was conducted following the methodological framework suggested by Arksey and O'Malley. In this scoping review, 65 research articles published before 31 January 2020 were analyzed and discussed to better understand the epidemiology, causes, clinical diagnosis, prevention and control of this virus. The research domains, dates of publication, journal language, authors' affiliations, and methodological characteristics were included in the analysis. All the findings and statements in this review regarding the outbreak are based on published information as listed in the references. RESULTS: Most of the publications were written using the English language (89.2%). The largest proportion of published articles were related to causes (38.5%) and a majority (67.7%) were published by Chinese scholars. Research articles initially focused on causes, but over time there was an increase of the articles related to prevention and control. Studies thus far have shown that the virus' origination is in connection to a seafood market in Wuhan, but specific animal associations have not been confirmed. Reported symptoms include fever, cough, fatigue, pneumonia, headache, diarrhea, hemoptysis, and dyspnea. Preventive measures such as masks, hand hygiene practices, avoidance of public contact, case detection, contact tracing, and quarantines have been discussed as ways to reduce transmission. To date, no specific antiviral treatment has proven effective; hence, infected people primarily rely on symptomatic treatment and supportive care. CONCLUSIONS: There has been a rapid surge in research in response to the outbreak of COVID-19. During this early period, published research primarily explored the epidemiology, causes, clinical manifestation and diagnosis, as well as prevention and control of the novel coronavirus. Although these studies are relevant to control the current public emergency, more high-quality research is needed to provide valid and reliable ways to manage this kind of public health emergency in both the short- and long-term.

OBJECTIVE: To determine the transmission characteristics of Cysticercuscellulose infections from a social network perspective in Tibetan school children in Sichuan. METHODS: A cluster sampling strategy was adopted to select two primary schools with high level of Cysticercuscellulose infections in the Tibetan agriculture areas of Liangshan prefecture, Sichuan province. All of the students from the selected schools were enrolled in the study. Their social network data, including classroom seating, dormitory roommates, best playmates, and those who shared meals and snacks etc, were collected by trained investigators. Stool and blood samples of the students were collected for parasite detection. The transmission network of Cysticercuscellulose infections and the overall social network of school children were analysed. RESULTS: A total of 644 children participated in the study. Taenia solium were found in 6.11% of the stool samples and 13.25% blood samples returned with seropositive. The transmission was centered around the sources of infections: dormitory-clustering in the boarding school and playmate-clustering in the day school. The overall social network analysis revealed "core people" (more relationships), "information disseminators" (closer to other nodes) and "information hubs" (between two nodes) in both schools. CONCLUSION: Close contacts in dormitories and playgrounds are the main sources of transmission of cysticercosis in the Tibetan schools. The "core people" "information disseminators" and "information hubs" are critical for the prevention and control of cysticercosis in the future.

Few food frequency questionnaires (FFQs) have been developed to assess diet in diabetes patients. This cross-sectional study examined the validity of a 45-item FFQ assessing the intake of macronutrients against three 24-h dietary recalls (24-HDRs) in Taiwan, and compared vegetable and fruit intakes with carotenoid biomarkers. We recruited 126 adults with type 2 diabetes who completed the FFQ and three 24-HDRs administered by a registered dietitian. We measured plasma carotenoids (α-carotene, ß-carotene and lutein) in 71 subjects. Partial Pearson correlation coefficients derived from the FFQs and three 24-HDRs and adjusted for energy were of 0.651, 0.587, 0.639 and 0.664 for protein, fat, carbohydrate and fiber, respectively. Cross-classification analysis revealed that 71.5â»81% of the macronutrients and fiber were categorized into the same or adjacent quartiles by the FFQ and 24-HDRs. Blandâ»Altman plots revealed good agreement for energy/macronutrients/fiber across the range of intakes. Multiple linear regression of backward elimination revealed that tertile levels of dark- or light-colored vegetables obtained by the FFQ were significantly associated with plasma α-carotene and ß-carotene, but not lutein. Fruit consumption did not correlate with carotenoid biomarkers. In conclusion, this short FFQ provided a valid assessment of macronutrients and fiber intake in type 2 diabetes patients. Vegetable consumption estimated by the FFQ corresponded to plasma α-carotene and ß-carotene concentrations.

BACKGROUND: Being overweight is a common problem among chronic schizophrenic patients. However, these patients lack related exercise interventions that are both effective and convenient. PURPOSE: To explore the effects of a biosensing game intervention on the health-related fitness of chronic schizophrenic patients. METHODS: Two rehabilitation wards at a psychiatric hospital in New Taipei City were selected as the study sites. Simple random sampling was used to recruit participants. Participants in the experimental group received a 12-week biosensing game intervention, while participants in the control group received routine nursing care only. The study instruments included a demographic data sheet and anthropometric measurements. In addition, health-related fitness variables including cardiovascular endurance, muscular endurance, flexibility, and body composition (e.g., body mass index (BMI), waist-hip ratio, and body fat) were used as outcome indicators. RESULTS: A total of 35 patients participated in the experimental group and 35 patients participated in the control group. The results showed that the mean differences between the pre-test and post-test values for body weight (t=6.07, p<.01), BMI (t=5.79, p<.01), and waist-hip ratio (t=2.87, p<.05) differed significantly, with the experimental group performing better than the control group on all three indicators. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The results indicate that this 12-week intervention holds the potential to help chronic schizophrenic patients improve their health-related fitness, especially in terms of body weight, BMI, and waist-hip ratio. This study may be used as a reference for the promotion of health-related fitness programs in psychiatric institutes in the future.

Samples of carboxylate-fluorapatite are prepared with citric, tricarballylic, and glutaric acids under hydrothermal conditions. The size of the hexagonal rods differs significantly for the three samples, of which the citric-acid sample exhibits the smallest dimension along the [h00] direction. The solid-state NMR data reveal that all the citrate molecules of citrate-fluorapatite are in direct contact with the fluorapatite surface and that there are at least two binding modes accounting for the interaction between citrate and fluorapatite surface. In addition to the electrostatic interaction between the carboxylate carbons and the calcium ions, some citrate molecules also form hydrogen bond between the hydroxyl group of citrate and the orthophosphate ion of fluorapatite. This hydrogen-bond interaction is highly ordered and may play an important role in the formation of the spherulites.

Phase transformation between calcite and aragonite is an important issue in biomineralization. To shed more light on the mechanism of this process at the molecular level, we employ solid-state (43)Ca NMR to study the phase transformation from calcite to aragonite as regulated by magnesium ions, with (43)Ca enrichment at a level of 6%. Using the gas diffusion approach, the phase of Mg-calcite is formed initially and the system subsequently transforms to aragonite as the reaction time proceeds. Our (43)Ca solid-state NMR data support the dissolution-recrystallization mechanism for the calcite to aragonite transition. We find that the (43)Ca NMR parameters of Mg-calcite are very similar to those of pure calcite. Under the high-resolution condition provided by magic-angle spinning at 4 kHz, we can monitor the variation of the (43)Ca NMR parameters of the aragonite signals for the samples obtained at different reaction times. Our data suggest that in the presence of a significant amount of Mg(2+) ions, aragonite is the most stable polymorph of calcium carbonate. The initial precipitated crystallites of aragonite have spine-like morphology, for which the (43)Ca spin-lattice relaxation data indicate that the ions in the lattice have considerable motional dynamics. As the crystallinity of aragonite improves further, the (43)Ca T(1) parameter of the aragonite phase changes considerably and becomes very similar to that obtained for pure aragonite. For the first time, the difference in crystal morphologies and crystallinity of the aragonite phase has been traced down to the subtle difference in the motional dynamics at the molecular level.

BACKGROUND & AIMS: We examined associations between the first-week energy and protein intake and clinical outcomes in medical ICU (MICU) patients who survived at least seven days. METHODS: We retrospectively studied 295 patients admitted to a 28-bed MICU between 2005 and 2007. High and low energy delivery (ED) and protein delivery (PD) were defined as having a mean daily intake relative to recommendation at ≥ 60% and <60%, respectively, during the 1st to 7th day of ICU stay. RESULTS: The high and low ED or PD groups did not differ with regard to length of ICU stay, length of hospital stay, or ventilator free time. Patients with low ED or low PD intake were at greater risk of mortality than their high intake counterparts (OR = 3.7 and 3.6; both p < 0.001). After adjusting for confounders, we found patients receiving low ED to be at 2.43 times the risk of ICU mortality than high ED (p = 0.020). Low PD was unrelated to ICU mortality. CONCLUSIONS: Patients receiving less than 60% of recommended energy intake during the first week of critical illness are at greater risk of mortality. There is a need for future randomized trials to investigate optimal energy delivery during critical illness.

This cross-sectional study analyzed the effects of two single nucleotide polymorphisms (SNP) of the adiponectin gene, SNP45 and SNP276, on hyperglycemia in indigenous Taiwanese, and whether central obesity modulates the effects of these SNPs. Overall, 550 indigenous Taiwanese were recruited for this cross-sectional study. The subjects were categorized into a hyperglycemic group if fasting plasma glucose was > 126 mg/dL (n = 88) or the control group if fasting plasma glucose was < 100 mg/dL (n = 462). The SNP276 TT homozygote carried greater hyperglycemia risk than SNP276 GG [odds ratio (OR) = 2.67, 95% confidence interval (CI) = 1.05-6.78], but not heterozygote (OR = 1.54, 95% CI = 0.95-2.50). SNP45 T > G was not associated with hyperglycemia risk. In multivariate-adjusted modeling, we found a significant relationship between SNP276 T carriers (GT + TT) (OR = 2.06, 95% CI = 1.10-3.88) and central obesity (OR = 4.50, 95% CI = 1.91-10.61) with hyperglycemia. Compared with non-central-obese carriers of SNP276 GG, non-central-obese SNP276 T carriers, and central obese subjects with SNP276 GG and SNP276 T carriers had 5.50, 8.31 and 13.76-fold, respectively, higher risks for hyperglycemia; obese carriers of the T-containing variants experienced a combined risk for hyperglycemia. Furthermore, the hyperglycemic risks were more pronounced in leaner (non-central-obese) individuals carrying the T variant than the central-obese individuals. The adiponectin SNP276 T variant and central obesity had independent and additive effects on hyperglycemia risks. These findings may provide valuable information regarding preventive strategies that might be useful to prevent or treat diabetes and its related complications.
